Energy efficiency is said to be "the cheapest form of energy we can get" and a great opportunity towards sustainability and environmental protection. Efficient and clean technology is many times available and needs to be leveraged.

The objective of this project is to allow easy access to knowledge and to facilitate the development of new initiatives developing, delivering or promoting energy efficient technology.

Carbon Capture and Storage (CCS) at any price?

Submitted by Hans Nilsson on Thu, 2007-05-24 07:00.

The cost of CCS-technology is high (as with all new technologies for that matter) and may have drawbacks. Standard and Poor, more known for credit-rating, has announced figures between 450 and 900 USD/kW to be added to the plant cost in the area of 2500-3000 USD/kW. On top of that, there will be a power loss of 15-25% per annum for the operation. Furthermore, there are legal risks for the storage leakage.

It is easy to see the interest from S&P if they should advise on financing for such technologies. Their point that energy efficiency is important, and utilities should perhaps be more rewarded for that than just selling more energy, is well taken, but how?
