MIT researchers devise simple catalytic system for fixation and conversion of CO2
March 05, 2014
Researchers at MIT have devised a simple, soluble metal oxide system to capture and transform CO2 into useful organic compounds. More work is needed to understand and to optimize the reaction, but this approach could offer an easy and inexpensive way to recapture some of the carbon dioxide emitted by vehicles and power plants, says Christopher Cummins, an MIT professor of chemistry and leader of the research team.
The new reaction, described in an open access paper in the RSC journal Chemical Science, transforms carbon dioxide into a negatively charged carbonate ion, which can then react with a silicon compound to produce formate, a common starting material for manufacturing useful organic compounds. This process relies on the simple molecular ion molybdate: an atom of the metal molybdenum bound to four atoms of oxygen.
DOE soliciting projects in advanced coal gasification for high carbon-capture power production and/or liquid fuels
February 26, 2014
The US DOE is soliciting (DE-FOA-0001051) projects for up to $10 million in awards to target technological advancements to lower the cost of producing hydrogen and/or high-hydrogen syngas from coal for use in 90% carbon capture power generation and/or gasification-based liquid (transportation) fuel production: methanol or diesel. Liquid fuel production must be GHG equivalent to conventional petroleum-based processes.
The work is also designed to assure significant reduction in the cost of coal conversion and environmental impacts, enabling coal resources to both improve US economic competitiveness and provide environmental benefits over the globe, according to the DOE.
DOE proposing $100M in FY2014 for 2nd round of funding for Energy Frontier Research Centers
October 01, 2013
US Energy Secretary Ernest Moniz announced a proposed $100 million in FY2014 funding for Energy Frontier Research Centers; research supported by this initiative will enable fundamental advances in energy production and use.
The Department of Energy (DOE) currently funds 46 Energy Frontier Research Centers (EFRCs), which were selected for five-year funding in 2009. (Earlier post.) With support for those centers set to expire in July 2014, DOE has announced a “re-competition” for a second round of funding (DE-FOA-0001010).
Kawasaki Heavy to build first ocean-going liquid hydrogen tanker with demo in 2017; H2 for transport, industry, power in Japan

The Nikkei reports that Kawasaki Heavy Industries Ltd. (KHI) will build the first ocean-going ships to carry liquefied hydrogen (LH2), with plans for a demonstration test by 2017 in which liquefied hydrogen will be shipped from the state of Victoria in Australia to Japan. The project will cost ¥60 billion (US$610 million), according to the report.
As part of Japan’s WE-NET (World Energy Network) research program of the New Sunshine Project begun in 1993, Kawasaki and its other industrial colleagues in Japan have been considering the large-scale marine transportation of liquid hydrogen for some time (e.g., Abe et al., 1998). KHI has previously discussed the concept of such a hydrogen-carrying vessel as part of its Business Vision 2020.
UMTRI survey explores receptivity of drivers to on-board carbon capture technology
September 17, 2013
Researchers at the University of Michigan Transportation Research Institute (UMTRI) recently conducted an online survey of driver option to determine how receptive drivers would be to adopting—and how much they might pay for—in-vehicle technology that reduce carbon emissions.
The driver survey is the team’s second study on this topic; the first, published in 2012, provided a general review of the area, with a primary focus on post-combustion technologies for light vehicles: absorption; membrane separation; and adsorption. The first study concluded that factors that might affect driver acceptance of in-vehicle carbon capture included the added initial cost of the technology; the probable on-board storage required; possible impact on fuel economy; and changes in the routine tasks involved in vehicle upkeep. The researchers—John M. Sullivan, Michael Sivak, and Brandon Schoettle—developed the second study, the driver survey, directly to probe drivers on these issues.
DOE releases draft of $8B loan guarantee solicitation for advanced fossil energy projects
July 03, 2013
The US Department of Energy (DOE) released a draft for comment of an $8-billion loan guarantee solicitation for innovative and advanced fossil energy projects and facilities that substantially reduce greenhouse gas and other air pollution. The program is part of President Obama’s climate action plan. (Earlier post.)
The Advanced Fossil Energy Projects solicitation, authorized by Title XVII of the Energy Policy Act of 2005 through Section 1703 of the Loan Guarantee Program, will be open for comments from industry, stakeholders, and the public until early September.
USGS assessment finds mean CO2 storage potential of 3,000 gigatonnes in US

The United States has the potential to store a mean of 3,000 gigatonnes of carbon dioxide in geologic basins throughout the country, according to the first detailed national geologic carbon sequestration assessment released today by the US Geological Survey (USGS). The assessment comes on the heels of a national climate action plan announced by President Obama. (Earlier post.)
The US Energy Information Administration (EIA) estimates that in 2011, the United States emitted 5.5 metric gigatons of energy-related CO2, while the global emissions of energy-related CO2 totaled 31.6 metric gigatons.
New LLNL technique for CO2 capture also produces green hydrogen and alkalinity to offset ocean acidification
May 28, 2013
Researchers at Lawrence Livermore National Laboratory (LLNL) have discovered and demonstrated a new technique to remove and store atmospheric carbon dioxide while generating carbon-negative hydrogen and producing alkalinity, which can be used to offset ocean acidification. A paper on their work appears this week in the Proceedings of the National Academy of Sciences.
The team demonstrated, at a laboratory scale, a system that uses the acidity normally produced in saline water electrolysis to accelerate silicate mineral dissolution while producing hydrogen fuel and other gases. The resulting electrolyte solution was shown to be significantly elevated in hydroxide concentration that in turn proved strongly absorptive and retentive of atmospheric CO2.
Stanford GCEP awards $6.6M to 7 projects; focus on combining energy conversion with carbon-neutral fuel production
March 13, 2013
Stanford’s Global Climate and Energy Project (GCEP) is awarding $6.6 million to seven research teams—six from Stanford and one from Carnegie Mellon University—to advance research on technologies for renewable energy conversion to electricity or fuels and for capturing CO2 emissions and converting CO2 to fuels.
The 7 awards bring the total number of GCEP-supported research programs to 104, with total funding of approximately $125 million since the project’s launch in 2002.
