Berkeley Lab nanoscale imaging study yields key insights into photo-electrochemical water splitting

Green Car Congress

In the quest to realize artificial photosynthesis to convert sunlight, water, and carbon dioxide into fuel—just as plants do—researchers need to not only identify materials to efficiently perform photoelectrochemical water splitting, but also to understand why a certain material may or may not work.

Argonne study compares life cycle emissions of battery-grade lithium carbonate and lithium hydroxide from brines and ores

Green Car Congress

Researchers at Argonne National Laboratory have conducted life cycle analyses (LCAs) for battery-grade lithium carbonate (Li 2 CO 3 ) and lithium hydroxide monohydrate (LiOH•H 2 O) produced from Chilean brines (Salar de Atacama) and Australian spodumene ores. This information will help us achieve our goal of being carbon neutral by 2030.

Researchers provide insight into OER electrocatalyst

Green Car Congress

The process involves subjecting methane to pressurized steam in the presence of a catalyst, creating a reaction that produces hydrogen and carbon monoxide, as well as a small amount of carbon dioxide. In the last step, pressure-swing adsorption, carbon dioxide and other impurities are removed, leaving behind pure hydrogen.

Insight into benzene formation could help development of cleaner combustion engines

Green Car Congress

The researchers say that their findings, recently published in an open-access paper in the journal Science Advances , are key to understanding how the universe evolved with the growth of carbon compounds. That insight could also help the car industry make cleaner combustion engines. This work was supported by the DOE Office of Science.

New photochemical diode artificial photosynthesis system doubles efficiency of solar water splitting

Green Car Congress

Researchers in Canada have demonstrated a new photochemical diode artificial photosynthesis system that can enable efficient, unassisted overall pure water splitting without using any sacrificial reagent. overall water splitting reaction. The device could also be reconfigured to turn carbon dioxide back into fuel.

Haldor Topsoe to build large-scale SOEC electrolyzer manufacturing facility to meet customer needs for green hydrogen

Green Car Congress

With efficiencies above 90%, Topsoe’s proprietary SOEC electrolyzers offer superior performance in electrolysis of water into hydrogen—e.g., SOECs can be used for direct electrochemical conversion of steam (H 2 O), carbon dioxide (CO 2 ), or both into hydrogen (H 2 ), carbon monoxide (CO), or syngas (H 2 +CO), respectively.

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. We knew it was unstable—but we were surprised to learn just how unstable it really is.
