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. —senior author Professor Erwin Reisner.

New system for more efficient CO2 electrolysis to hydrocarbon products

Green Car Congress

The researchers combined a copper electrocatalyst with an ionomer [polymers that conduct ions and water] assembly that intersperses sulfonate-lined paths for the H 2 O with fluorocarbon channels for the CO 2. By applying this design strategy, we achieved CO 2 electroreduction on copper in 7 M potassium hydroxide electrolyte (pH ?

SLB introduces low-carbon alternative for well construction cement that eliminates up to 85% of embodied CO2

Green Car Congress

The technology fits within standard oilfield cementing workflows without major changes to the design process, onsite execution, or postjob evaluation. This barrier also protects fresh water aquifers and helps prevent the inflow of undesirable hydrocarbons. million cars from the road each year.

New highly efficient catalyst for photoelectrochemical CO2 reduction toward methane

Green Car Congress

Experimentally, the designed CuFe catalyst exhibits a high current density of ?38.3 The design of the catalyst is critical to the success of the reaction. The copper and iron hold onto molecules by their carbon and oxygen atoms, buying time for hydrogen to make the leap from the water molecule fragments onto the carbon atom.

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

Green Car Congress

By understanding how materials and devices transform under operation, we can design approaches that are more durable and thus reduce waste. Electron microscopy experiments at the Molecular Foundry confirmed that cuprous oxide quickly oxidizes or corrodes within minutes of exposure to light and water. Zheng, F.,

Berkeley Lab team validates bio-analogous technique for converting CO2 into liquid acetate

Green Car Congress

Based on those previous studies, Yang and his team reasoned that artificial photosynthesis devices equipped with a copper catalyst should be able to convert CO 2 and water into methyl and carbonyl groups, and then turn these products into acetate. Researchers from Berkeley Lab and UC Berkeley participated in the study.

DOE selects 2 projects to demonstrate feasibility of enhanced water recovery; producing usable water from CO2 storage sites

Green Car Congress

The US Department of Energy (DOE) has selected two projects that will test emerging enhanced water recovery (EWR) technologies for their potential to produce useable water from CO 2 storage sites. Once treated, the clean water could be re-used for beneficial purposes, including supplemental cooling water at a power station.
