Differences Between Geothermal Energy and Shale Gas Stimulation Explained
An article from Philippe Dumas and Luca Angelino of the European Geothermal Energy Council explains differences between Enhanced Geothermal Systems (EGS) and shale gas operations. The article on Renewableenergyworld.com explains that both industries use stimulation techniques based on high-pressure injection of water, however, the target is different, either heat or gas. “Shale gas is locked in rocks, typically with low permeability in sedimentary basins, in a dispersed form without fluid. Geothermal power production targets semi-permeable rocks, so the pressure of the required injection is lower,” the experts explain.

Biomass MATOC Awards Announced for Defense Contracts
The final technology for renewable and alternative energy Multiple Award Task Order Contract (MATOC) awardees under the U.S. Army Corps of Engineers was biomass, and the 13 qualified biomass companies will now be considered for future Defense department Requests for Proposals. Awards for geothermal, solar, and wind were announced previously. “We look forward to continuing to build strong relationships with industry and our defense communities, which will help us remain a strong Army,” said Katherine Hammack, assistant secretary of the Army for installations, energy and environment in a Armyeitf.com press release.
