Stanford faculty awarded $2.2 million for innovative energy research; fuel cells, hybrids, splitting CO2
October 30, 2013
Stanford University’s Precourt Institute for Energy, the Precourt Energy Efficiency Center and the TomKat Center for Sustainable Energy have awarded 11 seed grants totaling $2.2 million to Stanford faculty for promising new research in clean technology and energy efficiency.
The seed funding supports early work on concepts that have the potential for very high impact on energy production and use. Through a competitive process, two committees of faculty and senior staff awarded the grants to Stanford researchers from a broad range of disciplines, including engineering, physics, economics, business, communication and education.
NRL researchers optimizing two-step process for synthesis of jet-fuel-range hydrocarbons from CO2
September 09, 2013
Researchers at the US Naval Research Laboratory (NRL) are investigating an optimized two-step process for the synthesis of liquid hydrocarbons in the jet fuel range from CO2 and hydrogen. The process, reported in the ACS journal Energy & Fuels, could leverage a recently reported process, also developed by NRL, to recover CO2 from sea water.
CO2 is 140 times more concentrated in seawater than in air on a weight per volume basis (g/mL), the authors note. With scaling and optimization of this CO2 recovery technology already underway, NRL researchers and others are working on new and improved catalysts for the conversion of CO2to useful hydrocarbons.
246th ACS National Meeting symposium on CO2 conversion to fuels
Converting CO2 to usable fuels was the topic of a symposium—CO2 Conversion: Thermo-, Photo- and Electro-Catalytic—on Sunday at the 246th National Meeting & Exposition of the American Chemical Society in Indianapolis, Indiana. (ACS is the world’s largest scientific society.)
Converting CO2 into a renewable energy sources would involve capturing the gas from the smokestacks of coal-fired electric power generating stations, for instance, and processing it with catalysts or other technology into fuels and raw materials for plastics and other products.
CAAFI R&D team releases critical challenges position paper and white papers for alternative jet fuel industry
August 06, 2013
The Commercial Aviation Alternative Fuels Initiative (CAAFI) R&D team released its current position paper on critical R&D challenges facing the alternative jet fuel industry, highlighting near-, mid-, and long-term priorities. The Position Paper is supported by a series of white papers describing the path forward on these key topics.
The position paper is the result a meeting last fall at which more than 80 members of the CAAFI R&D team—comprising a range of stakeholders from the aviation and alternative fuels industries, academia, and government—identified and discussed key immediate and longer-term needs for targeted funding to maximize the efficacy of the incipient alternative jet fuels industry. Critical enablers requiring immediate development are:
New inexpensive catalyst for conversion of CO2 to CO could help with storage of renewable energy
June 23, 2013
Researchers at the University of Delaware have developed an inexpensive bismuth−carbon monoxide evolving catalyst (Bi-CMEC) that can be used in conjunction with ionic liquids to convert CO2 to carbon monoxide (CO) using electricity. CO can then be reacted with H2O via the water−gas shift to generate H2, and this CO/H2 mixture (syngas) can be used to generate synthetic petroleum and liquid fuels using Fischer−Tropsch methods.
The combination, suggests the team in paper published in the Journal of the American Chemical Society, could integrate into energy storage and distribution networks to provide a means for renewable energy storage.
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.
UGA/NCSU team engineers hyperthermophilic bacterium to produce industrial chemical building blocks from CO2 and H2; ARPA-E project
March 26, 2013
Researchers at the University of Georgia and North Carolina State University have used a unique temperature-dependent approach in engineering a hyperthermophilic archaeon, Pyrococcus furiosus to be able to use CO2 and hydrogen to produce 3-hydroxypropionic acid, one of the top 12 industrial chemical building blocks.
The research, reported in the Proceedings of the National Academy of the Sciences (PNAS), was supported by the Department of Energy as part of the Electrofuels Program of the Advanced Research Projects Agency-Energy (ARPA-E) under Grant DE-AR0000081. (Earlier post.)
DOE launches Clean Energy Manufacturing Initiative; awards $23.5M to 5 more manufacturing R&D projects
The US Department of Energy (DOE) launched the Clean Energy Manufacturing Initiative (CEMI), which will focus on growing US manufacturing of clean energy products and boosting US competitiveness through major improvements in manufacturing energy productivity. The initiative includes private sector partnerships, new funding from the Department, and enhanced analysis of the clean energy manufacturing supply chain that will guide DOE’s future funding decisions.
As a part of its increased focus on manufacturing research and development, DOE also awarded $23.5 million to 5 innovative manufacturing research and development projects. This new funding for advanced manufacturing—as well as the $54 million invested in 13 projects during the first round of selections in June of 2012 (earlier post)—is to serve as a ground floor investment in CEMI.
UNSW team develops bio-inspired catalytic approach to chemical reduction for production of fuels and chemicals
March 25, 2013
Scientists at the University of New South Wales (Australia) have developed a new bio-inspired method for carrying out chemical reduction—an industrial process used to produce fuels and chemicals. A report on their work is published in the journal Angewandte Chemie.
Chemical reduction involves the addition of electrons to a substance, and is the basis of making many fuels, including the sugars that plants produce during photosynthesis. The catalyst designed by the team led by Associate Professor Stephen Colbran of the UNSW School of Chemistry mimics the activity of naturally occurring metallo-(de)hydrogenase enzymes that catalyse reduction, such as alcohol dehydrogenase in yeast, that helps produce alcohol from sugar.
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.
