OVERVIEW
At the October 2006 Workshop the BEA examined the advantages and opportunities for Clean Coal Technologies to help close the electricity supply gap. Recent UK and EU Reviews have recognised that CCT can increase security of supply, reduce power plant emissions, offer low and stable electricity costs and set a global example on CO2 emissions. As a natural follow-on to that discussion, we will now address some of the more interesting technologies that CCS is likely to promote.
Solid fuel gasification has, of course, been practiced over very many years. Latterly, a number of IGCC power plants have been built and generally have done little to enhance the reputation of this technology. The introduction of CCS using Pre-Combustion Capture for hydrogen production and power generation brings impetus to the development of clean and effective gasification and syngas processing technologies. Nicolás Ximénez Bruidegom, General Manager for Shell's clean coal business in Europe, examined some of the technical advances taking place in this area.
Will large-scale gas turbines actually run on hydrogen? If so, what modifications to the standard design are needed? What are the issues in the balance of plant? Can existing plant be modified? Can they run on hydrogen-enriched gas? Terry Raddings of GE International addressed these questions and more.
When CCS becomes a parameter in new power plant design it causes a fundamental re-think of principles. Rather than separate CO2 from the flue gas, why not separate the O2 from air to produce a pure CO2 Stream for compression and storage. Vince White (Air Products), outlined the principles, the economics and the opportunities that come with Oxyfuel Combustion.
SPEAKERS
| Clean Coal Energy - Gasification and CCS |
Nicolás Ximénez Bruidegom, of Spanish nationality but born and raised inThe Netherlands, joined Shell in 1995 following a degree in aeronautical engineering. He started his career as a mechanical engineer in gasification technologies and spent 2 years in the Buggenum IGCC facility as project manager and operations manager. Following a series of assignments in NL, UK and Germany in commercial roles, he returned to the field of gasification early in 2006, as General Manager Clean Coal Energy Europe of Shell Gas & Power International BV.

| Oxyfuel Power Generation - Technical Development and Opportunities |
Vince White started work at Air Products over 10 years ago after completing a PhD in Chemical Engineering at Imperial College. He is currently responsible for the development of CO2 capture technologies for Air Products in Europe, particularly oxyfuel. He has been involved in several CO2 capture studies, and was Air Products' main contributor to the recent IEA GHG study on oxyfuel CO2 capture from coal power stations, as well as the current UK DTI funded projects on CO2 capture from coal power plants. |
