want to join you as a mamber,whats the procedure


I understand NRG Energy will be building a igcc plant in tonawanda ny. Is this project still on or is NRG just talking big with no action
Please post any findings


IGCC for Afsin Elbistan lignite Fields in Turkey

Dear Energy Professional, Dear Colleagues
On 31st October, 2007, we were in Afsin Elbistan coal mine and thermal power plant premises to participate "Clean Coal Technologies" for 3-day workshop, which was organized by Chambers of Mining, Mechanical, Chemical and Electrical Engineers of Turkey. The existing power plants (Groups A and B) are based on pulverized coal firing technology which need relatively higher calorific value plus less moisture. Indirect type Pulverized coal firing technique can be successful only if you lower the moisture content and hence with higher the calorific value. Available coal has a challenging content with very poor Low calorific value at about average 1150 kcal per kg, and 55% moisture, 20% ash, 1.5-4% sulphur. The thermal power plants, named A and B each had with 1400 MWe installed electric generating capacity at full load. There is another new tender for Units C&D. It is our sincere feeling that IGCC could be a good choice for the new units. IGCC (Integrated Gasification combined cycle) firing technology could be employed. Here in this technology you build a sort of refinery to generate "Synthetic gas" from poor lignite then you fire this synthetic gas in the combined cycle power plants similar to natural firing. Seems to be logical but we doubt if it is applicable for our lignite. It was successful in North Dakota as built by “General Electric” and funded by “USA Department of Energy”. Here in our country who will decide to move on and who will finance?? These researches are prepared and presented to decision-makers of Ministries. These are to be shared by the public in order to reach "Common Wisdom" and to be directed accordingly for the best interest of our country. Clean Coal Technologies Workshop in Elbistan will create a great opportunity for all interested local parties to enable them to learn from past mistakes, to investigate the possible/ applicable technologies, to investigate and assess the available intellectual capability of the local human resources. Thank you & best regards

Panel on "Clean Coal Technologies" in ODTU Alumni in Ankara

Dear Energy Professional, Dear Colleagues,

We had a meeting on Saturday afternoon 23rd February 2008 at the main conference room of "Chamber of Engineers" head office in Ankara Thessalonica Street. The meeting was held with participation of leading senior/ retired members of local energy business, former General Managers, former operation managers, senior researchers of various public enterprises, as well as senior local energy experts.

The subject was "Clean Coal Technologies" which is actually the code name for Integrated Gasification Combined Cycle technology. IGCC is a new technology to answer global warming.

This new technology produces synthetic gas from coal. Synthetic gas has almost one fourth of the heating value of average natural gas.

IGCC technology is first innovated by Germans during WW2 to produce gas and/or liquid fuel for the fighting war vehicles in an environment with no petroleum resources, and further developed in South Africa during world embargo against their apartheid practices in their domestic politics.

Since the equivalent cost per barrel is/was around 50 US Dollars for the synthetic fuel, it was not feasible in the past to apply "clean coal technologies" since it had no chance of competition against low petroleum prices then. However the time has changed and petroleum now costs more than 100 US Dollars per barrel, therefore IGCC technology is now an attractive fuel option.

Our guest speaker, Dr Iskender Gokalp is a Turkish national scientist, Directeur in ICARE, Institut de Combustion, Aérothermique, Réactivité et Environnement, UPR3021 du Centre National de Recherche Technologique, "Propulsion du Futur" in 1c, Av. de la Recherche Scientifique, 45071 Orléans cedex 2, France, http://www.cnrs-orleans.fr/icare/

He comes to Turkey, to his homeland, one week for each month to pursue and execute a project to grand PhD scholarships to young Turkish engineers/ scientists in France on coal utilization, combustion technologies, supported by Turkish Coal Board and European Union under current FB7 program.

He created many scientific publications, and also had great influence in international scientific circles. He recommends us to carry out more research on "Clean Coal Technologies" on local Turkish Lignite specifically on low heating value coal mines, to justify its application and competitiveness.

He advises that local lignite coal could be the best option for application of integrated gasification. Your humble writer sincerely feels that Dr.Iskender GOKALP has all reason to advise on application of "Clean Coal Technologies" in local lignite reserves.

It is also our sincere feeling that clean-coal technology is a must. Energy tops the agenda of all local winter meetings. Next-generation coal is going to need to continue to be part of our energy future for our country. It is abundant, it is locally available, in the sense that we control the supply.

Next-generation coal typically refers to capturing and somehow sequestering or storing the carbon that coal produces. It also envisions reducing or eliminating emissions as coal is burned. It is possible to continue relying on the fossil fuel while minimizing its impact on the environment.

We cannot ignore coal, we should find better ways to utilize local lignite coal. That is important because electricity demand will ever increase in the future.

We all know that Coal has a CO2 problem, Wind has a reliability problem, Solar has a price problem, Nuclear power plants have price, radiation and unsafe disposal problem, so all of those technologies have opportunities and they all have problems.

What we can say about coal, is that we have it locally. We have it in a greater supply.

Synthetic gas production could be a bid expensive but the rest of the system is well-known combined cycle power plant.

Prevailing overall market price is around 1200- 1500 US dollars per KW installed capacity for 600-1000 MWe power plant test sizes. By localizing the technology, we can substantially reduce that first installations cost.

On the other hand local low LHV lignite has current fuel cost less than 2 (two) US Dollars per million BTU gross, whereas imported coal cost is 6- 8 US Dollars gross, Natural gas cost is around 8-10 US Dollar, and imported LNG price in spot market is around 17-18 USD per million BTU.

Senior experts have an ideefixe for application of IGCC on high heating value bituminous coal or steam coal. On the other hand, Dr Gokalp says that IGCC has potential application on low heating value lignite. It is for sure that we do not know if IGCC is perfect match for our lignite. All we have to do is to allocate more funds for more research on local lignite.

We shall have a panel on "Clean Coal Technologies" in ODTU Alumni Association Visnelik premises in Ankara on 10th March 2008 Monday at 1900 hours.

Dr Iskender Gokalp will be one of four distinguished panelists. The other panelists are Prof Dr Bekir Zuhtu UYSAL, Director of Clean Energy Institute of Gazi University, Dr Selahaddin ANAÇ GM of Turkish Coal Board, and Mr. Orhan Baybars ME'79, former site construction manager of Afsin Elbistan-B thermal power plant.

Panel will be conducted in Turkish, and it is open for all interested parties. Entrance is free-of-charge. We have free coffee/ tea services. Please do participate if you would be in Ankara on that day. Your comments are always welcome.

Thanks for a nice, straightforward post on IGCC.

I've tried using the link in the gasification section to view the EPRI presenation, but unfortunately seems to no longer work. I was surprised by some of the statements there.

The gasification section makes no mention of BGL gasifier. Basically a recent development on dry ash gasifiers, it has many of the positive features of entrained flow gasifiers such as dry coal feed, cooled refractory lining, and continuous removal of ash in the form of slag rather than dry ash.

Unlike the entrained flow gasifiers the gas/coal flow is countercurrent, resulting in much cooler gas exit temperatures - hence lower capital costs as specialised heat-resistant materials are not needed. Due to the longer coal residence times, the BGL gasifiers use less oxygen and steam, but also achieves a higher efficiency rate in converting coal to gas, giving lower operating costs. The potential drawback of the BGL gasifier is the amount of methane produced - a drawback for Fischer Tropsch synthesis of hydrocarbon liquids, but a positve advantage for production of syngas. For simply burning the gasifier product in an IGCC turbine, the methane content is unlikely to be a crucial issue.

More info on the BGL gasifier can be found on http://www.gl-group.com

How do plants dispose of the oxygen they generate? Like, you know how everyone is like "plants are good because they breath in carbon dioxide and breath out oxygen?" Well where exactly does it "breath out" the oxygen? Then what happens to the glucose that the plant produces by breathing in the Carbon Dioxide? Thanks!

There are a bunch of chemicals that can kill plants. I would assume a lot of different cleaning chemicals and even household salt could kill a plant.


On the other hand local low LHV lignite has current fuel cost less than 2 (two) US Dollars per million BTU gross, whereas imported coal cost is 6- 8 US Dollars gross, Natural gas cost is around 8-10 US Dollar, and imported LNG price in spot market is around 17-18 USD per million BTU.

IGCC Power Plant is useful because it can be found in abundance of America and many other countries and because the price of it has remained relatively constant in recent years. These non-utility plants have recognized the need to treat the gasification system.


The type of exercise you do all depends on you and what you like to do. What you hate doing, paying membership fees, and whether or not to buy equipment are all things you need to consider as well as answer.


Many very good recommendations in here by the people. My own tips for weightless: Do lots of physical exercise and consume lots of water for weight control remedy.

The third level is more "conceptual" and seems to require some "thinking". But this is not necessarily an exclusively human ability: indeed, when a dog learns that bringing back the stick will get him a stroke, this is also some kind of induction.

interesting! although I have no expert, but I want to have to know more and more, on your blog just a myriad of interesting and useful information. Keep it up!
