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.

Mærsk, Wallenius Wilhelmsen, BMW Group and others partner to explore blend of lignin and ethanol for sustainable shipping fuel

Green Car Congress

Shipping requires bespoke low-carbon fuel solutions which can make the leap from the laboratory to the global shipping fleet. Lignin is a structural bio-polymer which contributes to the rigidity of plants. The marine sector has very different fuel requirements than automotive or aviation.

Startup New Oil Resources commercializing hydrothermal process for conversion of biomass to gasoline-range hydrocarbons

Green Car Congress

320-390 °C, 200-420 bar) aqueous phase process which converts biomass containing cellulose, hemicellulose and lignin into a high-octane gasoline fraction. New Oil Resources’ process uses near-critical water to treat the biomass in a process commonly referred to as hydrothermal liquefaction or thermal depolymerization.

Volkswagen to produce XL1 diesel plug-in hybrid at Osnabrück; 261 mpg US

Green Car Congress

Operating at 220 volts, the power electronics manage the flow of high voltage energy from and to the battery or E-motor and converts direct current to alternating current. The body electrical system of the XL1 is supplied with the necessary 12 Volts via a DC/DC converter and a small auxiliary battery. Equipped in this way, the 0.8

ICCT study concludes no technical barriers to use of higher blends of ethanol

Green Car Congress

This in turn raises temperatures inside the catalytic converter, and over time, this can accelerate catalyst deterioration. In addition, excess oxygen in the exhaust can inhibit proper functioning of the catalytic converter and lead to increased emissions of NO x. Phase separation of water and ethanol from gasoline.

XL1 dive and drive: Volkswagen aggressively optimizes for efficiency in its sleek diesel plug-in hybrid

Green Car Congress

The XL1 is aggressively optimized for efficiency in all areas of its design and technology—from materials (carbon fiber reinforced polymer monocoque); to powertrain (0.8L XL1 represents the third evolutionary stage of Volkswagen’s 1-liter car strategy, referring to the goal set by Prof. Earlier post.).
