Researchers develop earth-abundant photocatalyst for conversion of ammonia into hydrogen

Green Car Congress

and Princeton University’s Andlinger Center for Energy and the Environment have created a scalable photocatalyst that can convert ammonia into hydrogen fuel. This result demonstrates the potential for highly efficient, electrically driven production of hydrogen from an ammonia carrier with earth-abundant transition metals.

Stanford researchers make ammonia from air and water microdroplets

Green Car Congress

Water (H 2 O) microdroplets are sprayed onto a magnetic iron oxide (Fe 3 O 4 ) and Nafion-coated graphite mesh using compressed N 2 or air as the nebulizing gas. This gas–liquid–solid heterogeneous catalytic system synthesizes ammonia in 0.2 The conversion rate reaches 32.9 ± 1.38 —Song et al.

Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Sandia National Laboratories researchers recently delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. The system uses heated supercritical carbon dioxide instead of steam to generate electricity and is based on a closed-loop Brayton cycle.

Blue World Technologies starting production of methanol fuel cells

Green Car Congress

Methanol fuel cell developer and manufacturer Blue World Technologies ( earlier post ) is starting limited production—the first step in commercializing its methanol fuel cell technology. Methanol reforming is a relatively simple process that converts a mix of methanol and water into a hydrogen-rich gas.
