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.

Mercedes-Benz wins landmark road monitoring program in the Netherlands; connected vehicle data

Green Car Congress

Mercedes-Benz has been awarded a far-reaching contract for road monitoring through vehicle data by the Netherlands’ Ministry of Infrastructure and Water Management (Min I&W). The raw material for this is anonymized data from car-to-X or other systems from intelligent, connected Mercedes-Benz vehicles.

First reference installation of Opcon Waste Heat Recovery technology for ships; potential for 5–10% fuel savings

Green Car Congress

Opcon, in collaboration with Wallenius Marine, recently completed the first reference installation of its Waste Heat Recovery technology for ocean-going vessels in a project supported by the Swedish Energy Agency. Waste heat is used by a heat exchanger to vaporize a working fluid with a boiling point lower than water. The MV Figaro.

Monash study on solar-driven electrolysis for green hydrogen production cautions on life-cycle emissions and EROI

Green Car Congress

of hydrogen is currently produced via water electrolysis and only a fraction of this production is powered by renewable energy. Taking IRENA’s REmap scenario as a reference, renewable hydrogen could deliver 5% of total final energy demand in 2050. According to the IEA, less than 0.1% solar generation exceeding electrolyzer capacity).

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

Green Car Congress

Twelve has developed an efficient polymer-electrolyte membrane (PEM) CO 2 electrolyzer that uses proprietary CO 2 -reducing catalysts to split CO 2 with just water and renewable electricity as inputs, syngas (CO and hydrogen) as the output, and pure oxygen as the only byproduct. Formerly Opus 12, Twelve is based in Berkeley, California.

NREL researchers capture excess photon energy to produce solar fuels; higher efficiency water-splitting for H2

Green Car Congress

The advancement could significantly boost the production of hydrogen from sunlight by using the cell to split water at a higher efficiency and lower cost than current photoelectrochemical approaches. A salt bridge connects the two compartments and transports H + and Na +. The research is outlined in a paper in Nature Energy.
