The Department of Energy announced, last night (August 11) 15 projects aimed at creating secure CO2 underground storage

However, this morning one of the schemes The FutureGen Coal Project has reportedly pulled out of the deal.

Bosses behind Illinois based FutureGen said that Government changes to the scheme were a’ deal breaker’.

The US government believes more than 1100 years of CO2 storage potential in its geologic formations.

To benefit from this US energy secretary, Steven Chu, announced the selection of 15 projects to develop technologies aimed at safely and economically storing carbon dioxide in geologic formations.

Funded with $21.3 million over three years the schemes will develop the technology and infrastructure to implement large-scale CO2 storage in different geologic formations across the nation.

“The projects announced today are part of this Administration’s commitment to leading the world in carbon capture and storage technology,” said Mr Chu.

“These projects will reduce greenhouse gas emissions, develop clean energy innovation and help produce jobs for Americans across the nation.”
