New photocatalytic system converts carbon dioxide to valuable fuel more efficiently than natural photosynthesis

Green Car Congress

The new system mimics a natural chloroplast to convert carbon dioxide in water into methane, very efficiently using light. Photosynthesis is the process by which chloroplasts in plants and some organisms use sunlight, water and carbon dioxide to create food or energy.

Zhejiang team develops photo-chemo-biocatalytic pathway to convert triolein to biogasoline

Green Car Congress

Researchers from Zhejiang University in China have developed a photo-chemo-enzymatic multi-step combination pathway for the highly efficient and environmentally friendly preparation of biogasoline from cheap and sustainable triolein using solar energy and atmospheric O 2 under mild conditions.

New process uses localized surface plasmons for room-temperature conversion of CO2 to CO

Green Car Congress

Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have demonstrated a room-temperature method that could significantly reduce carbon dioxide levels in fossil-fuel power plant exhaust, one of the main sources of carbon emissions in the atmosphere.

Researchers use chemical looping process to produce hydrogen from hydrogen sulfide gas

Green Car Congress

The process uses relatively little energy and a relatively cheap material—iron sulfide with a trace amount of molybdenum as an additive. The team first used chemical looping on coal and shale gas to convert fossil fuels into electricity without emitting carbon dioxide into the atmosphere.

Global Bioenergies plans to acquire Dutch start-up Syngip; gaseous carbon feedstocks for renewable isobutene process

Green Car Congress

Global Bioenergies, the developer of a process to convert renewable resources into light olefin hydrocarbons via fermentation (with an initial focus on isobutene) ( earlier post ), signed a contribution agreement with the shareholders of Syngip B.V. to transfer all Syngip shares to Global Bioenergies S.A.

China researchers synthesize high-density aviation fuel with cellulose

Green Car Congress

Scientists in China have developed a process for converting cellulose from plant waste from agriculture and timber harvesting into high-density aviation fuel: a polycycloalkane mixture. Li and his team found that cellulose can be selectively converted to. 2,5-hexanedione using hydrogenolysis.

New nanolithia cathodes may address technical drawbacks of Li-air batteries; scalable, cheap and safer Li-air battery system

Green Car Congress

Further, the cathode is automatically protected from O 2 gas release and overcharging through the shuttling of self-generated radical species soluble in the carbonate electrolyte. You need large auxiliary systems to remove the carbon dioxide and water, and it’s very hard to do this.” It also displays stable cycling performance (only 1.8%
