Cambridge researchers develop standalone device that makes formic acid from sunlight, CO2 and water

Green Car Congress

Researchers at the University of Cambridge, with colleagues at the University of Tokyo, have developed a standalone device that converts sunlight, carbon dioxide and water into formic acid, a carbon-neutral fuel, without requiring any additional components or electricity.

Researchers develop new stable artificial photosynthesis device to produce ethylene and hydrogen from sunlight and CO2

Green Car Congress

A research team has developed a new artificial photosynthesis device component with remarkable stability and longevity as it selectively converts sunlight and carbon dioxide into two promising sources of renewable fuels: ethylene and hydrogen. The device produced ethylene and hydrogen with unprecedented selectivity and for more than 24 hours.

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.

SOLAR-JET project demonstrates solar-driven thermochemical conversion of CO2 and water to jet fuel

Green Car Congress

SOLAR-JET concentrated thermochemical reactor. The EU-funded SOLAR-JET project has demonstrated the production of aviation kerosene from concentrated sunlight, CO 2 captured from air, and water. The solar reactor consists of a cavity-receiver containing a porous monolithic ceria cylinder. Click to enlarge.

New highly efficient catalyst for photoelectrochemical CO2 reduction toward methane

Green Car Congress

The work, presented in a paper in Proceedings of the National Academy of Sciences (PNAS), offers a unique, highly efficient, and inexpensive route for solar fuels synthesis. The solar-powered catalyst is made from abundant materials and works in a configuration that could be mass-produced. 1 under air mass 1.5 —Zhou et al.

RPI researchers to develop novel porous material for air capture of CO2

Green Car Congress

In those areas, we can use this technology to capture CO2 from the air and then combine that with the hydrogen generated from solar energy in order to produce liquid fuel. In his previous work, he’s developed membranes capable of capturing CO 2 while filtering-out other molecules like water. —Miao Yu.

PSI team demonstrates direct hydrocarbon fuel production from water and CO2 by solar-driven thermochemical cycles

Green Car Congress

Solar-driven thermochemical cycles offer a direct means of storing solar energy in the chemical bonds of energy-rich molecules. By utilizing a redox material such as ceria (CeO 2 ) as a reactive medium, STCs can produce hydrogen and carbon monoxide—i.e., syngas—from water and CO 2. —Lin et al.
