Bio-sketch

Robert H. Williams is a Senior Research Scientist at the Princeton Environmental Institute (PEI), Princeton University, where he heads the Energy Systems/Policy Analysis Group. Under PEI’s BP/Ford-supported Carbon Mitigation Initiative (CMI), he also leads the Carbon Capture Group. He (and colleague Eric Larson) are also involved in an intensive research collaboration with a group in the Thermal Engineering Department at Tsinghua University in Beijing that is exploring clean energy technologies and strategies for China based on coal and biomass gasification.
 
Trained as a physicist (BS, physics, Yale, 1962; PhD, theoretical plasma physics, UC Berkeley, 1967), Williams joined the Physics Department, U. of Michigan, Ann Arbor, in 1970, where he shifted his research from basic physics to energy and environmental analysis. In 1972 he became Chief Scientist with the Ford Foundation's Energy Policy Project, where he was responsible for environmental and energy efficiency research. He joined Princeton University’s Center for Energy and Environmental Studies in the fall of 1975 and PEI in 2001.

Lead Author (2008-2009) for Knowledge Module on Fossil Energy Systems (Conventional and Advanced) for the Global Energy Assessment
 
Technical Advisor (2007-2008) to the National Energy Technology Laboratory for its
Coal/Biomass to Liquids study  
 
Member (2007), Working Group on Coal to Liquids of the Transportation Fuels Initiative of the Western Governors Association (WGA), and coauthor of Coal-to-Liquids Report to the WGA
 
Advisor (2006) to the International Energy Agency in the preparation of a chapter of World Energy Outlook 2006 on the need to bring about a shift from biomass and coal to clean fluid fuels for cooking.
 
Lead Author for the IPCC Special Report on CO2 Capture and Storage of the Intergovernmental Panel on Climate Change (IPCC), December 2005. 
 
Member (1998-2004), Editorial Board of the World Energy Assessment (WEA). The WEA was a joint project of the UN Development Programme, the UN Department of Economic and Social Affairs, and the World Energy Council. The WEA was initiated in response to the outcome of the Special Session of the UN General Assembly in 1997 ("Rio Plus Five" meeting) that reviewed progress in addressing the Agenda 21 goals established at the 1992 UN Conference on Environment and Development in Rio de Janeiro. That 1997 meeting declared that the ninth session of the Commission on Sustainable Development (CSD-9) in 2001 should focus specifically on energy and transport issues. The book Energy and the Challenge olf Sustainability—The World Energy Assessment (2000) was prepared to inform discussion and debate about sustainable energy as an input to both CSD-9 and the "Rio Plus Ten" meeting of the UN General Assembly in 2002. In 2002 WEA sponsors requested that an updated Overview of the World Energy Assessment be prepared, and this was published in 2004. As a member of the WEA Editorial Board and Convening Lead Author of the Advanced Energy Supply Technologies Chapter (Chapter 8 of the WEA), Williams participated in the preparation of this revised overview.
 
International Member (1993-2003), Working Group on Energy Strategies and Technologies (WGEST) for Phases I and II of the China Council for International Cooperation on Environment and Development (CCICED). For Phase III of the CCICED (begun in 2002), working groups were replaced by task forces, and Williams was an international member of the Task Force on Energy Strategies and Technologies (TFEST), which for the period through 2003 focused on policies for advancing polygeneration (co-production of synthetic fuels, chemicals, and electricity from coal via gasification) in China.
 
Member (1992-   ), Board of Directors, International Energy Initiative (IEI).
 
Member, Energy R&D Panel of the President’s Committee of Advisors on Science and Technology (PCAST, 1997) and Chair of the Panel’s Renewable Energy Task Force.
 
Member, PCAST Panel on International Cooperation in Energy Research, Development, Demonstration, and Deployment (1999) and Chair of the Panel’s Energy Supply Task Force.
 
Member (1995-1998), Scientific and Technical Advisory Panel (STAP) of the Global Environment Facility (GEF) and Chair of the STAP Climate and Energy Working Group.
 
Lead Author (1994-1995), IPCC Working Group IIa (Energy Supply Mitigation Options) for the IPCC’s Second Assessment Report.
