U.S. Congress Tells EPA to Study Hydraulic Fracturing and Drinking Water

Five years ago the U.S. Environmental Protection Agency assured the nation that the technology credited with opening vast new natural gas supplies was safe. Now Congress has ordered the agency to take another look.

As part of the $32 billion Interior and Environment Appropriations Bill recently signed by President Obama, lawmakers asked the EPA to re-visit hydraulic fracturing, the process where copious amounts of water and sand mixed with toxic chemical additives are furiously pumped underground to break up gas-bearing rock thousands of feet below.

DOE’s Arpa-e Pumps $151 Million Into Innovative Energy Research Projects

written by Yale Environment 360

The U.S. Department of Energy will pump $151 million into 37 innovative energy-related research projects through a new federal agency modeled after the Defense Department program that helped commercialize microchips and the Internet.

The Advanced Research Projects Agency-Energy, or Arpa-e, created in 2007 to support innovative and often-experimental projects, selected the first round of grant recipients from 3,600 proposals.

While many of the ideas may never lead to practical breakthroughs, Energy Secretary Steven Chu said some could have a “transformative impact.”

Among the first grant recipients are University of Minnesota researchers attempting to develop an organism that uses sunlight to convert carbon dioxide to sugars and diesel fuel; a Massachusetts Institute of Technology team developing an all-liquid metal battery that could better manage the output from intermittent energy sources such as wind and solar; and a United Technologies effort to capture carbon emissions from power plant stacks using enzymes.
