NPL novel reference electrode shows that cathode, not anode, is source of potential decay in PEM water electrolyzers

Green Car Congress

Scientists from the National Physical Laboratory (NPL) in the UK have developed a novel reference electrode for polymer electrolyte membrane water electrolyzers (PEMWEs) and used it to measure the electrochemical surface area (ECSA) of Pt catalysts in situ for the first time. Reference electrode configuration. Source: NPL.

GWU team suggests C2CNT carbon nanotube composites could amplify reduction of GHG emissions

Green Car Congress

Stuart Licht reports that the addition of carbon nanotubes (CNTs) produced from CO 2 by low-energy C2CNT (CO 2 to CNT) molten electrolysis ( earlier post ) to materials such as concrete or steel not only forms composites with significantly better properties, but amplifies the reduction of CO 2. A) Carbon mitigation with CNT-cement. (B)

Oxford team directly converts CO2 to jet fuel using iron-based catalysts

Green Car Congress

The catalyst shows a carbon dioxide conversion through hydrogenation to hydrocarbons in the aviation jet fuel range of 38.2%, with a yield of 17.2%, and a selectivity of 47.8%, and with an attendant low carbon monoxide (5.6%) and methane selectivity (10.4%).

BNEF report finds hydrogen promising decarbonization pathway, but carbon prices and emissions policies required

Green Car Congress

Note: Clean hydrogen refers to both renewable and low-carbon hydrogen (from fossil-fuels with CCS). Renewable hydrogen can be made by splitting water into hydrogen and oxygen, using electricity generated by cheap wind or solar power. Renewable energy has paved the way to carbon-free electricity.

C-Zero raises $11.5M Series A to produce clean hydrogen from natural gas via methane pyrolysis

Green Car Congress

C-Zero’s technology, which was initially developed at the University of California, Santa Barbara, uses innovative thermocatalysis to split methane into hydrogen and solid carbon in a process known as methane pyrolysis. The methane decomposition reaction is moderately endothermic; the energy requirement per mole of hydrogen produced (8.9

Twelve produces first batch of E-Jet fuel from CO2 electrolysis; partnership with USAF; electrifying fuel, not planes

Green Car Congress

Carbon transformation company Twelve (formerly Opus 12, earlier post ) has produced the first fossil-free jet fuel—called E-Jet—from CO 2 electrolysis, demonstrating a scalable, energy-efficient path to the de-fossilization of global aviation. Global aviation produces 1.2 —Twelve Co-Founder and CEO Nicholas Flanders.
