New Solar Energy Conversion Process Could Boost Efficiency

Green Car Congress

Stanford engineers have developed a process—photon-enhanced thermionic emission, PETE—that simultaneously uses the light and heat of the sun to generate electricity in a way that could make solar power production more than twice as efficient as existing methods. (a) a) Energy diagram of the PETE process. b) One possible implementation.

Berkeley Lab solar-to-fuel system for CO2 to ethanol and ethylene; light-powered production of fuel via artificial photosynthesis

Green Car Congress

Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have harnessed the power of photosynthesis to convert carbon dioxide into fuels and alcohols at efficiencies far greater than plants. Solar to chemical energy conversion could provide an alternative to mankind's unsustainable use of fossil fuels.

DOE announces $100M for artificial photosynthesis research to two major partnerships

Green Car Congress

The Liquid Sunlight Alliance (LiSA) , led by the California Institute of Technology in close partnership with Lawrence Berkeley National Laboratory, is pursuing an approach called “co-design,” which is an effort to make the many complex steps in converting sunlight to fuels work more efficiently both individually and in concert with each other.

Lux Research: cost of electrofuels remains far from viable

Green Car Congress

The cost of electrofuels—fuels produced by catalyst-based systems for light capture, water electrolysis, and catalytic conversion of carbon dioxide and hydrogen to liquid fuels—remains far away from viable, according to a new analysis by Lux Research. Biotech Fuels Solar' Hydrogen-to-fuels.

Tunable high-yield catalytic approach converts pyrolysis oil to bio-hydrocarbon chemical feedstocks including fuel additives

Green Car Congress

Pyrolysis bio-oils are produced by the thermal decomposition of biomass by heating in the absence of oxygen at more than 500 °C; fast pyrolysis of biomass is much less expensive than biomass conversion technologies based on gasification or fermentation processes. —Vispute et al.
