How to Succeed in Bringing New Green Energy Technologies to Market

submitted by: RASEIBoulder
Summary: In our work at E Source we analyze lots of energy efficiency, renewable energy, and demand response technologies. The first thing we do is determine whether or not they are technically capable of providing the benefits that their vendors claim. That’s the easy part.

Carbon Capture and Storage: What Are the Big Issues and Opportunities for Future Energy Resources?

submitted by: RASEIBoulder
Summary: Carbon Capture and Storage (CCS) can make significant cuts in Greenhouse Gas emissions and will need to be part of the forward planning for developing future global energy resources. CCS technology comprises a number of steps: 1) CO2 is captured at the source (e.g., a power plant or gas production facility); 2) the captured CO2 is compressed to a supercritical state and transported, typically via pipeline, from the source to the geologic storage site; 3) the CO2 is injected via...
