Missouri City Goes 100% Wind Power

Following the opening of a new 5 MW four-turbine wind farm last week, Rock Port, a town of 1,395 in North West Missouri, has become the first U.S. town to get all its electricity from wind power. The $90 million Loess Hills Wind Farm, was built by St. Louis-based Wind Capital Group and the John Deere Corp.

When fully operational, the four Suzlon 1.25 MW S-64 wind turbines will have the capacity to generate 16 million kilowatt hours a year. Historically, Rock Port electrical customers use approximately 13 million KwH annually.

Missouri Joint Municipal Utilities will buy excess power from the farm, expected to eventually generate 16 million kilowatt hours of electricity per year. As part of this powerpurchase agrreement  MJMU will supply Rock Port's power needs when the wind turbines are not generating at capacity.

Optisolar to Build Largest Solar Farm in North America

OptiSolar, Hayward, California, is developing a 550 megawatt photovoltaic (PV) solar farm, the largest in North America, covering over 6,000 acres, in San Luis Obispo County, California.

OptiSolar intends to submit an application to San Luis Obispo County for a Conditional Use Permit (CUP) in May. Construction is targeted to begin in 2010, after completing the local approval process. Installation of panels will occur over a period of up to three years.

OptiSolar is a vertically intigrated company manufacturing its own solar cells and panels and claims its amorphous silicon thin-film solar PV panels combine proprietary manufacturing processes and innovative design to yield affordable, durable panels that significantly reduce the cost of clean solar power. Their thin-film design requires only about 1% of the silicon used in crystalline systems, thus not being affected by the availability of crystalline silicon. The companies technology enables low-profile solar panels to be placed on simple concrete and steel ballasts with minimal grading.

Although photovoltaic solar panels are currently less efficient than solar thermal systems, OptiSolar claims that its solar cells are significantly more cost effective as they require less expensive silicon during manufacture, consume little water, and require far less maintenance than turbine based systems. In addition they avoid the need for large structures that turbine-based systems require, and do not result in the noise associated with such systems.

OptiSolar Farms Canada has 21 solar project  in Canada under various phases of development including the 60-megawatt "Sarnia Solar" park, which will be broken into six construction phases with the first 10-megawatt phase expected to be completed by year's end and the balance competed in 2009.

EPRI Analysis Finds Utility Based Energy Efficiency Programs Could Cut Energy Consumption 7-11 %

Energy efficiency improvements in the U.S. electric power sector could reduce electric consumption by 7 to 11 percent more than currently projected over the next two decades if key barriers can be addressed, according to a preliminary analysis of potential energy savings released recently by the Electric Power Research Institute (EPRI) and the Edison Electric Institute (EEI) during an Edison Foundation conference which examined strategies to meet the growing demand for electricity which is expected to soar 30 percent by 2030, according to the U.S. Energy Information Administration.

“This study demonstrates the potential of energy efficiency to offset some of the projected need for new electric generation as cutting-edge technologies become available and are adopted. We think a 7-percent efficiency improvement is realistic – and gains of 11 percent or more are technologically feasible – depending on the degree to which various obstacles can be overcome.”

-- Dr. Michael Howard, senior vice president at EPRI

That demand growth projection would be even higher without the implementation of existing building codes, appliance standards and market-driven consumer incentives, which will shave electricity consumption by 23 percent, according to the EPRI-EEI study. However, additional efficiency gains could be achieved only by overcoming major market, regulatory and consumer barriers, the analysis found.  . . .

Essential steps include increased consumer education; adoption and enforcement of aggressive building codes and appliance standards; creation of utility business models that promote increased efficiency within the power sector; and adoption of electricity pricing policies that more accurately reflect the cost of providing electricity to consumers – and give them the information they need to use it wisely.  . . .

At the same time, consumers’ ever-increasing appetite for electricity-hungry devices – even with continuing efficiency improvements – will keep electricity demand on a steady upward trajectory. A 42-inch plasma television consumes two and a half times more energy (250 watts) than a standard 27-inch TV (100 watts). And while many large household appliances have become more efficient over the years, many smaller devices have not. Two 30-watt set-top television boxes, for example, may consume as much electricity as a large refrigerator.

eSolar Receives Funding for 33MW Modular Solar Power Plants

From a 4/21 press release:

eSolar™, a producer of modular solar thermal power plants, announced (pdf) that is has closed $130 million in funding from Idealab, Google.org, Oak Investment Partners, and other investors for the construction and deployment of pre-fabricated power plants. Their distributed solar thermal plants achieve economies of scale at 33 MW, and are modularly scaled to fit the needs of large and small utilities.

"The eSolar™ power plant is based on mass manufactured components, and designed for rapid construction, uniform modularity, and unlimited scalability. Rather than over-engineering the solution, eSolar’s smart scalable solar architecture targets what we see as the four key business obstacles facing the sector: price, scalability, rapid deployment, and grid impact."

-- Asif Ansari, CEO of eSolar.

. . . Centering on eSolar’s 33 MW pre-fab form-factor, the company’s modular design translates to minimal land requirements. The company’s solar power plant solutions are tailored to fit local resources and produce a low environmental footprint, favoring a straightforward siting and permitting process.

. . . eSolar has secured land rights in the southwest United States to support the production and transmission of over 1 GW of power. eSolar will have a fully operational power plant later this year in southern California.

From their website:

The economic tipping point, for solar power, occurs when the capital cost of the solar field is less than the capital costs and fuel costs of the traditional system. To address this issue, eSolar has developed a modular power plant architecture designed to take advantage of mass manufactured components at every level.

Order your Tesla Roadster Now, TH!NK City Coming to North America in 2009

On Earth Day it is appropriate to feature one of the most sustainable products of the future, the electric car. High gas prices and growing environmental consciousness could finally usher in a new era for electric cars. The Tesla Roadster and the TH!NK City, represent the two extremes in electric vehicle choices and they are among the first, if not the first, electric cars scheduled to go into production.

With the announcement, on March 17, that Tesla Motors had achieved their goal of starting regular production of the Tesla Roadster, the company claimed that the modern era of the electric car had begun.

While this is an important milestone for the company and a watershed for the new era of electric vehicles, we still have a lot of work to do. Our key focus with the Roadster will be on gradually ramping up our production in a deliberate and controlled manner reaching a rate of over 100 Roadsters per month early next year.

Ze'ev Drori, President and CEO, Tesla Motors

With a 0 to 60 mph acceleration of 3.9 seconds, a 13,000 rpm redline, the Roadster has the fastest top gear acceleration of any production car tested by Car & Driver magazine in 2007, With an EPA rating of 135 MPG equivalent, the Roadster provides super car performance at twice the energy efficiency. The batteries provide a range of more than 200 miles (333 km) between charges. The Roadster runs on 6,831 laptop computer batteries stuffed in a car, assembled by Britain's Lotus.

More than 1,000 customers have ordered the $98,000 2008 Roadster, according to the company. The estimated base price for the 2009 Roadster is $109,000. Final pricing will be announced just prior to the start of 2009 production.Tesla started production, making one or two cars a week, but it says it will steadily increase production  to around 100 cars a month by early next year. Tesla had to delay production by about six month primarily due problems with the transmission.  The company is now involved with lawsuits with both suppliers and competitors.

Think Global, the Norwegian electric car producer, along with RockPort Capital Partners and Kleiner Perkins Caulfield & Byers, announced this Monday plans to introduce the TH!INK City to the North American Market in 2009. 

The TH!NK city is currently produced in Norway and international sales are scheduled to begin in Scandinavia, with Switzerland and France also being the initial focus areas. Sales, other than initial trial and demonstration projects, will begin in the North American market in 2009.

"The TH!NK city is the world's only crash-tested and highway-certified electric vehicle and is ideal for markets such as California where we will initiate demonstration projects offering an exceptionally safe and fun car to drive."

-- Jan-Olaf Willums, CEO of Think Global

Study Develops More Accurate CO2 Data

Purdue University press release: - A new, high- resolution interactive map of U.S. carbon dioxide emissions from fossil fuels has found that the emissions aren't all where we thought.

"For example, we've been attributing too many emissions to the northeastern United States, and it's looking like the southeastern U.S. is a much larger source than we had estimated previously.

"When you compare the old inventories to Vulcan, the new data show atmospheric CO2 differences that are as large as five parts per million in some U.S. regions in the late winter. The levels in the global atmosphere only rise one and a half part per million every year, so this is the equivalent of three years of global emissions in the atmosphere that isn't where we thought it was. This will be important for policy-makers and is enormous from a scientific point of view. It's shocking."

-- Kevin Gurney, Project leader and assistant professor of earth and atmospheric science at Purdue University.

The maps and system, called Vulcan, show CO2 emissions at more than 100 times more detail than was available before. Until now, data on carbon dioxide emissions were reported, in the best cases, monthly at the level of an entire state. The Vulcan model examines CO2 emissions at local levels on an hourly basis.

Largest Laser Beam in the World to Create Fusion

This video is about the National Ignition Facility, more details in previous post, at Lawrence Livermore National Laboratory, employing the largest bank of laser beams in the world, to be used in an experiment designed to create fusion ignition, a potential clean energy source for the 21st century. The $3.5 billion complex is under construction and expected to start full operations in 2009.

Scientists are creating a system to replicate fusion by using lasers to create the high heat and pressure needed for fusion. At the center of the project is a gold cylinder the size of a dime. This gold cylinder, called the hohlraum, houses a capsule containing the hydrogen isotopes – the fuel for the fusion reaction. NIF scientists will blast the hohlraum with 192 laser beams simultaneously (containing a total of 1.8 million joules of energy, about 500 trillion watts) for a few billionths of a second. The cylinder will produce x-rays that compress and heat the capsule resulting in a nuclear fusion reaction.

This experiment is not a continuous fusion reactor, it is an experimental device designed to determine whether scientists can create a fusion reaction for an instant of time, using this method. It does not produce any continuous output as ITER is designed to, It is one of the first major steps designed to see if lasers can be used to create fusion.

The ITER Tokamak, a $13 billion magnetic containment device, is based on totally different technology and would be the first fusion device to produce thermal energy at levels equivalent to conventional electricity power plants.

Several other containment devices are being tested throughout the world, in an attempt to develop a device that is superior to that used in ITER. The technology used in ITER is the most advanced and thus was selected for use in that ground breaking experiment.

Pickens Wind Farm to Get Underway

Texas oil man T. Boone Pickens is commencing action, with plans for his company, Mesa Power, to build, over the next four years, the previously announced $10 billion wind farm, the world's largest, that will eventually generate 4,000 megawatts of electricity - the equivalent of building two commercial scale nuclear power plants - enough power for about 1 million homes.

Next month Mesa Power, will begin buying land and ordering the first 500 wind turbines of the 2,700 turbines required for the project, at about $2 million each, to be located across 200,000 acres of the Texan panhandle.

"Don't get the idea that I've turned green. My business is making money, and I think this is going to make a lot of money."

-- Pickens in the Guardian

Pickens grand plan, not to be built by him, for resolving the energy needs of the US. is to build wind farms on a corridor of land running north to south through the middle of the US - along the great plains and to harvest solar energy from a corridor running east to west from Texas to southern California.

Pickens certainly thinks big, and somebody has to, as the U.S. government is doing little to resolve our compounding needs for new power sources. I assume thermal solar power would be used for the solar part of his plan as it currently is much less expensive than PV solar and thermal solar power can be quite easily adapted to thermal storage, although that brings the price up to where the total cost is quite expensive.

The only other comment I have is on Pickens grand scheme, and that would be to utilize geothermal power in addition to solar and wind.   Conventional geothermal would be used in the northwestern part of the U.S., primarily in California, Nevada, Idaho and Oregon, Hawaii and along parts of the New England coast. Hot dry rock or deep geothermal/EGS can be used in almost all of the U.S. and would serve the southern and eastern parts of the country, where solar and wind are not particularly applicable. The current cost of geothermal is comparable to natural gas power and thus is very attractive. Geothermal has the advantage of being a baseload power source, whereas wind and solar are not particularly suited for this application.  Thermal storage can be added to thermal solar but that would be more costly than geothermal. Significantly improved utilization of wind and solar can be obtained by tying geographically diverse sources together with an extensive grid. However, that is costly and would have to be studied in detail.

I personally think that a part of this plan would have to be to use generation III+ nuclear reactors and clean coal with sequestration to compliment the renewable power portions of this plan. This will be required to improve the baseload properties of the grid and provide the required power we need until the renewable power providers have built up sufficient capability. If Pickens, through his companies, can finance a $10 billion project that will supply 4 gigawatts of power, I would think that there would be several other companies, utility companies in particular, that could spend that much and supply all the incremental needs for power. Companies like Glitner and Chevron are capable of very large geothermal plants. Other diversified oil companies could get into the act as the supplies of oil get even more expensive and the world turns to electrictity as a larger and larger share of its power supply.

Trina Solar Cancels $1 Billion Polysilicon Plant

China-based Trina Solar (NYSE: TSL) announced that it has canceled plans to build a $1 billion polysilicon plant that was revealed in December of 2007, with a target completion date by the end of 2012. Favorable changes in the polysilicon market has led Trina to believe that it can now obtain sufficient polysilicon on the open market to meet its production requirements. 21 new firms started manufacturing polysilicon during 2007.

Trina also announced on 4/2/08 that it has entered an eight-year polysilicon supply agreement with GCL Silicon Technology Holdings Ltd.for enough polysilicon to produce about 2.6 gigawatts worth of solar modules. Trina has now secured about 95 percent of its estimated polysilicon requirements for 2008.

Trina previously had said that it was targeting solar module production capacity of 350 megawatts of annual capacity by the end of this year. Trina announced in late October 2007, that it had launched production on its new multicrystalline module line, complimenting its monosilicon module line.

In a somewhat related announcement Fluor Corporation said that it has been awarded the contract for engineering, procurement and construction management (EPCM) services by LDK Solar for its $1 billion, 15,000MT polysilicon plant in Xinyu City, Jiangxi, China.

High purity silicon ("Polysilicon") is the key feedstock for almost all solar cells and modules produced today. The solar PV industry and semiconductor manufacturers are the two main consumers of polysilicon. In 2000 the solar industry consumed only 10% of the world's silicon supply. In 2006 the PV industry consumed more than half of the world's available supply of polysilicon for the first time ever.

So Trina sees that it can obtain enough silicon from the open market, such that its own production facility is not needed.  Its recent agreement with GCL will supply nearly all of its silicon needs for the next eight years.  Meanwhile silicon suppliers such as LDK Solar continue to expand production. Does this mean that the silicon supply shortage is over?  My opinion is that, at this moment, there is not enough silicon production to allow the much needed expansion of the PV solar cell industry, but that facilities under construction will probably allow for some expansion.  The trend to use more thin film silicon PV and non-silicon PV will reduce requirements for silicon. How much is enough? This will depend on whether solar PV modules can reach the price target of under $1.00 per Wp that have been promised by some. In the meantime there is a market demand for more modules than can currently be produced at relatively high prices (Solarbuzz currently lists $3.74/Wp (€2.36/Wp) as the lowest price for thin film solar modules).

Climate Change Confirmed but Global Warming is Cancelled

I ran across an article, in The National Business Review (NZ), that (attempts to) explain why the climate is not highly sensitive to CO2 warming.

In December last year .  . . (the author) heard   . . . a paper . . . that showed while the IPCC models predict that greenhouse gases would produce an extensive "hot spot" in the upper troposphere over the tropics, the satellite measurements show no such hotspots have appeared.  . . .

a large part of this discrepancy is the result of some basic errors in the IPCC's assessment of the Stefan-Boltzmann equation. When they applied their revised factor to the effect of greenhouse gases, the temperature rise was about a third of that predicted by the IPCC.  . . .

The findings that the predicted "tropical hot spots" do not exist are important because the IPCC models assume these hot spots will be formed by increased evaporation from warmer oceans leading to the accumulations of higher concentrations of water vapour in the upper atmosphere, and thereby generating a positive feedback reinforcing the small amount of warming that can be caused by CO2 alone.  . . .

The Beginning of the End for Coal

A post on Earth Policy Institute describes the difficulty power companies are having in getting coal fired power plants approved. There first paragraph sums up the difficulty they are having:

With concerns about climate change mounting, the era of coal-fired electricity generation in the United States may be coming to a close. In early 2007, a U.S. Department of Energy report listed 151 coal-fired power plants in the planning stages in the United States. But during 2007, 59 proposed plants were either refused licenses by state governments or quietly abandoned. In addition, close to 50 coal plants are being contested in the courts, and the remaining plants will likely be challenged when they reach the permitting stage.

The post goes on to outline 18 events that have occurred in the last year that have contributed to this dilemma.  The latest action was the introduction of a bill in the House of Representatives that would block the EPA and states from issuing permits to new coal-fired power plants that lack state-of-the-art carbon capture and storage, CCS, technology. A comment added to this item was: Since this technology is at least a decade away from commercial viability, if this bill passes it would essentially place a near-term moratorium on new coal-fired power plants.

We have an urgent need for more power production and some way of providing this power must be provided. If the bill introduced in house should pass, as proposed, we would be dependent on renewable energy, nuclear power and conservation to provide the power in the near term. Since these options would not be sufficient, we could only hope that this bill would not pass or it would be modified before passage.

I disagree that CCS technology is at least a decade from commercial viability -- I believe that at least one technology will be successfully demonstrated in 5-7 years. We have at least four CCS technologies in the testing stage and I would propose that coal fired power plants be allowed to be built, 1) under more stringent conditions that the power is needed, 2) that they be located where carbon sequestration can take place and 3) that they be built so that the emerging CCS technologies can be easily adapted to the plant. Their are two ammonia based systems and two amine based systems that I am aware of. It may be necessary to pick one of these technologies or it may be possible to provide (perhaps massive) piping connections that would allow any process to be connected.

While many will say that conservation of electricity is the answer, it is only part of the solution. It will take many years before a structured plan could be put in place.  It may be possible that certain industries could be found where conservation could be mandated, if that can be done constitutionally. Higher prices for electricity may end up being the the greatest force causing conservation. Practices that reduce electrical consumption in the home have been written about by many and these should receive more widespread availability. A simple search on your favorite search engine using the search words "home electricity efficiency" brings up several sources including this one, How to Save Electricity in Your Home from the Edison Electric Institute.

Nuclear and Renewable energy simply cannot be brought up to speed fast enough to meet all our needs, although I think they should be accelerated as fast as possible.  Incentives for renewables should be maintained until the industries are fully sustainable. Geothermal energy has become my favorite renewable energy because it is a baseload power provider, and with new, hot dry rock, HDR, technology can be located in almost all areas of the world, as such it should receive much more funding for demonstration plants from the government. At least four geothermal projects, two funded by DOE and one in France and one in Germany using HDR technology are already underway. Although a large number of HDR plants could be built with existing technology, it might take 10 or 15 years before this technology can be applied universally.

An exception could be made on my, and the US governments, stand that only a few generation III+ nuclear plants can be be built until they have demonstrated that they can operated safely.  If it could be shown that the AP1000 and AREVA plants, and any other that meet US criteria, have been safely and successfully operated in a foreign country, the requirement for operation in the US could be waived.

FYI: Nanomaterial Turns Radiation Directly into Electricity

According to an article in New Scientist, materials that directly convert radiation into electricity could produce a new era of spacecraft and even Earth-based vehicles powered by high-powered nuclear batteries, say US researchers.  . . .

The materials they are testing would extract up to 20 times more power from radioactive decay than thermoelectric materials, they calculate.  . . .

Tests of layered tiles of carbon nanotubes packed with gold and surrounded by lithium hydride are under way.  . . .

The tiles would be best used to create electricity using a radioactive material, says Liviu Popa-Simil, former Los Alamos National Laboratory nuclear engineer and founder of private research and development company LAVM , because they could be embedded directly where radiation is greatest. But they could also harvest power directly from a fission reactor's radiation.

Devices based on the material could be small enough to power anything from interplanetary probes to aircraft and land vehicles, he adds.

Volt Status Update

GM released some more information on the status of the Chevy Volt plug-in hybrid last week in meeting with journalists and analysts at its battery research labs and design studio near Detroit. No real news to those of you who are following the Volt closely.

A Reuters article summarized the information quite well, also see this post in GCC. The main points are:

• Executives are still committed to launching the Volt by November 2010, calling it the "No. 1 priority project"
• GM has started testing of two 16 kWh, 170 kg battery packs, one from a subsidiary of Korea's LG Chem and the 2nd suppled by Continental AG using A123 Systems technology.
• The goal for the battery is to  be able to run at least 150,000 miles, last 10 years, provide 60-mph acceleration in less than 9 seconds and provide an all electric range of 40 miles.
• Testing some Volt-like technology in a 2005 Chevrolet Malibu began last year and battery testing in the Malibu will begin this month.
• Relatively small aerodynamic improvements have increased the electric range by more than half a mile.

Largest Tidal Stream System Installed

Marine Current Turbines, has successfully completed the first installation phase of the 1.2MW SeaGen Tidal System, previous post, the world’s largest grid-connected tidal stream system, into the fast-flowing waters of Strangford Narrows off the coast of Northern Ireland.

A crane barge safely positioned the 1000 ton structure onto the seabed in the early hours of Wednesday morning, 2 April, and released its four moorings on 3 April. SeaGen’s location is roughly 1km south of the ferry route between Strangford and Portaferry, approximately 400m from the shoreline.

When fully operational later in the summer, its 16m diameter, twin rotors, one shown above, will operate for up to 18-20 hours per day to produce enough clean, green electricity, equivalent to that used by a 1000 homes, four times greater than any other tidal stream project so far built.

“SeaGen is a hugely exciting project, as well as an historic achievement for both Marine Current Turbines and for renewables in the UK and Ireland. Tidal energy has the great advantage of being predictable and no other system can harness the power of the tidal currents in the way this one can. We take great pride and see enormous potential in the technology and hope it will eventually make a significant contribution to the future energy needs of the British Isles, Ireland and beyond.”

Skeptics Speak Out on Global Warming

Aqua satellite data suggests there are reasons why we should be skeptical to the extent to which carbon dioxide drives warming, that CO2-driven increases in water vapor actually cool the earth, not magnify warming, and with equal interest the latest data from Argos float buoy data in the ocean could suggest the ocean is cooling since 2003 when they became operational.

In a report posted on Australia’s ABC National on March 17th entitled “Climate Change,” Jennifer Marohasy of the Australian Environment Foundation comments on data from the NASA Aqua satellite:

“The satellite was only launched in 2002 and it enabled the collection of data, not just on temperature but also on cloud formation and water vapour. What all the climate models suggest is that when you’ve got warming from additional carbon dioxide this will result in increased water vapour, so you’re going to get a positive feedback. That’s what the models have been indicating. What this great data from the NASA Aqua satellite…and the first time this data has been able to be collected is 2002 so we’ve got a little bit of data now, it’s actually showing just the opposite, that with a little bit of warming, weather processes are compensating, so they’re actually limiting the greenhouse effect and you’re actually getting a negative rather than a positive feedback.”

DesignLine Orders 150 Capstone Turbines for HEV Buses

Capstone Turbine Corporation (NASDAQ: CPST), announced that it has received a 150 unit order for C30 Capstone MicroTurbines(R) to be deployed in ECOSaver IV hybrid electric buses manufactured by DesignLine International. This is the largest order to date for Capstone products in a Hybrid Electric Vehicle (HEV) application.

Hybrid electric buses equipped with Capstone microturbines, have been operating in various parts of the world for approximately 10 years. DesignLine buses are constructed with advanced extruded aluminum technology making them lightweight and very strong. The end result is the most fuel efficient vehicle available. In recent product demonstrations the ECOSaver IV hybrid buses equipped capstone turbines have seen up to a 100% improvement in fuel economy over a traditional diesel bus which equates to fuel savings of up to 6,000 gallons per year according to DesignLine.

The bus has a serial drive, running on batteries all the time, the turbine being only used to charge the batteries  The buses are also equipped with regenerative braking. In urban driving the buses get about seven miles per gallon. The buses were tested by the New York Metropolitan Transportation Authority for two month beginning in October 2007.

Standard nominal specification are: Top speed: 62 mph, Max gradient: 15%, Max Power: 250 KW, Max Torque: 2500 NM which may change depending on configuration selected.

FYI: TransAlta and Alstom Develping CCS Facility in Alberta

TransAlta Corporation (NYSE: TAC) and Alstom (EPA: ALO) signed an agreement to work together to develop a large scale CO2 capture and storage (CCS) facility in Alberta, Canada.

The project will pilot Alstom’s proprietary Chilled Ammonia Process.  TransAlta considers the Chilled Ammonia Process as one of the more promising and potentially lowest cost solutions for CCS. TransAlta’s plan with Alstom is to test the technology at one of TransAlta’s coal-fired generating stations west of Edmonton and reduce current CO2 emissions by one million tons per year. . . . more

A similar article can be found on Bloomberg.com

Every CCS project that is built is a step foreword in controlling CO2 emissions and brings us a step closer to being able to require CCS on all coal fired power plants. Alberta already has regulation that require companies to reduce their greenhouse gas emissions.

Waste Hydrogen Used to Power Vehicles and Car Wash

CBCnews (Canada) has an interesting story about how the Integrated Waste Hydrogen Utilization Project (IWHUP) uses hydrogen from two chemical plants to power pickup trucks, shuttle buses and a car wash.

The chemical plants produce more than 1000 kg/hr of hydrogen resulting form the production of sodium chlorate and clor-alkali by electrolysis of salt water. The waste hydrogen contains "chlorine, water vapor and other nasties," which have to be removed before it can be used.

Sacré-Davey Engineering saw that the hydrogen was being wasted by venting the hydrogen to the atmosphere and designed a C$18.3 million facility to treat, compress and deliver the hydrogen to two fueling stations— one in North Vancouver and the other in Port Coquitlam, a nearby suburb.

MIT Spin-off Developing Solar Cells That are 27% More Efficient, No more Expensive to Make

1366 Technologies claims that its small multicrystalline solar cells are 27% more efficient than conventional cells while keeping costs about the same.  It also announced its first round of funding of $12.4 million from Venture capitalists co-led by North Bridge Venture Partners and Polaris Venture Partners.

The company's efficiency and cost claims are based on results from small solar cells (about two centimeters across) made in the lab of professor of mechanical engineering Emanuel Sachs, who is one of the company's founders.

1366 Technologies is building a pilot-scale manufacturing plant that will make full-sized solar cells (about 15 centimeters across) that should yield results in about a year.

Sachs says that current solar cells cost about $2.10 per watt generated. When manufactured at a commercial scale, the first cells incorporating his new technology will cost $1.65 per watt while planned improvements will reduce the cost to about $1.30 a watt.

The company's solar cells include three key innovations to improve efficiency:

1. A method for adding texture to the surface of the cells that allows the silicon to absorb more light.
2. A method for making the current collecting wires as small as one-fifth the width of the wires that are typically used, while improving their conductivity.
3. A new Light-Capturing Ribbon that increases the efficiency of a solar module by reflecting light back onto the surface of the cell. This grooved ribbon replaces the traditional wires used to interconnect solar cells.

Professor Sachs previously invented the String ribbon™ wafer technology being commercialized at Evergreen Solar, a leading developer of solar energy products. Sachs is joined by 1366 Technologies co-founder and investor, Frank van Mierlo, who serves as the company’s president. Harvard Business School professor Joseph Lassiter rounds out the board of directors, all of whom hold degrees from MIT.
