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.

Siluria and Wood launch Modus: process technology to convert low-value offgas into high-octane, low-sulfur gasoline blendstock

Green Car Congress

The Modus process is based on a commercially proven catalyst system that converts light olefins, such as ethylene and propylene—often contained in refinery offgas streams—to high-quality gasoline blendstock with a 90+ octane rating and ultra-low sulfur content. Modus expands revenue sources and ultimately increases profitability.
