Rice U team creates low-cost, high-efficiency integrated device for solar-driven water splitting; solar leaf

Green Car Congress

Rice University researchers have created an efficient, low-cost device that splits water to produce hydrogen fuel. The current flows to the catalysts that turn water into hydrogen and oxygen, with a sunlight-to-hydrogen efficiency as high as 6.7%. It utilizes water and sunlight to get chemical fuels.

Argonne-led team develops new low-cost cobalt-based catalyst for PEM electrolysis

Green Car Congress

A multi-institutional team led by the US Department of Energy’s (DOE) Argonne National Laboratory (ANL) has developed a low-cost cobalt-based catalyst for the production of hydrogen in a proton exchange membrane water electrolyzer (PEMWE). volts (Nafion 212 membrane) and low degradation in an accelerated stress test.

Heliogen and Bloom Energy demonstrate production of low-cost green hydrogen; concentrated solar and high-temp electrolysis

Green Car Congress

When combined with Bloom’s proprietary solid oxide, high-temperature electrolyzer, hydrogen can be produced 45% more efficiently than low-temperature PEM and alkaline electrolyzers. Electricity accounts for nearly 80% of the cost of hydrogen from electrolysis. Source: Heliogen.

PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

By using a water-lean post-combustion capture solvent, (N-(2-ethoxyethyl)-3-morpholinopropan-1-amine) (2-EEMPA), they achieved a greater than 90% conversion of captured CO 2 to hydrocarbons—mostly methane—in the presence of a heterogenous Ru catalyst under relatively mild reaction conditions (170 °C and 2 pressure).

EPFL team develops low-cost catalyst for splitting CO2

Green Car Congress

EPFL scientists have developed an Earth-abundant and low-cost catalytic system for splitting CO 2 into CO and oxygen—an important step towards achieving the conversion of renewable energy into hydrocarbon fuels. Using only Earth-abundant materials to catalyze both reactions, this design keeps the cost of the system low.
