EPA announces 2016 Presidential Green Chemistry Challenge Award winners

June 14, 2016

The US Environmental Protection Agency (EPA) has announced the Presidential Green Chemistry Challenge Award winners. The annual awards recognize landmark green chemistry technologies developed by industrial pioneers and leading scientists that turn climate risk and other environmental problems into business opportunities, spurring innovation and economic development.

The Presidential Green Chemistry Challenge Award winners were honored at a ceremony in Portland, Ore. on 13 June. The winners and their innovative technologies are:

DOE selects 2 projects to demonstrate feasibility of enhanced water recovery; producing usable water from CO2 storage sites

June 05, 2016

The US Department of Energy (DOE) has selected two projects that will test emerging enhanced water recovery (EWR) technologies for their potential to produce useable water from CO2storage sites. The two projects were competitively selected from the five Brine Extraction Storage Test (BEST) projects awarded in September 2015.

The two projects will receive a total of $31 million in funding from the Department to implement their field plan to validate their proposed approaches. Of the total funding $5 to $6 million will be used to test EWR technologies.

New $30M ARPA-E program to produce renewable liquid fuels from renewable energy, air and water

April 26, 2016

The US Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) announced up to $30 million in funding for a new program for technologies that use renewable energy to convert air and water into cost-competitive liquid fuels. (DE-FOA-0001562)

ARPA-E’s Renewable Energy to Fuels through Utilization of Energy-dense Liquids (REFUEL) program seeks to develop technologies that use renewable energy to convert air and water into Carbon Neutral Liquid Fuels (CNLF). The program is focused in two areas: (1) the synthesis of CNLFs using intermittent renewable energy sources and water and air (N2 and CO2) as the only chemical input streams; and (2) the conversion of CNLFs delivered to the end point to another form of energy (e.g. hydrogen or electricity).

Argonne LCA study finds many alternative fuels consume more water than petroleum and natural gas fuels

March 09, 2016

Researchers at Argonne National Laboratory have analyzed the water consumption for transportation fuels in the United States using an extended lifecycle system boundary that includes the water embedded in intermediate processing steps.

In a paper published in the RSC journal Energy & Environmental Science, they compared the water consumed per unit energy and per km traveled in light-duty vehicles. They found that many alternative fuels consume larger quantities of water on a per km basis than traditional petroleum and natural gas pathways. The authors concluded that it will be important to consider the implications of transportation and energy policy changes on water resources in the future.
