Comparison of costs and MSPs for the DHH pathway with the direct hydrogenolysis pathway. The hydrogenation of 5-HY-Val in the presence of the 2-HY-THP monomers and dimers with a Ru catalyst results in 97% overall yield of 1,5-PD from DHP.The researchers refer to this routeas the dehydration, hydration, and hydrogenation (DHH) pathway.

EPIC: state-level renewable electricity mandates increase electricity prices up to 17% over 12 years; cost more expensive than benefit

Green Car Congress

As states take the lead in confronting climate change, a flagship policy is often Renewable Portfolio Standards (RPS). RPS programs, which require that a certain percentage of the state’s electricity come from renewable sources, currently cover 64 percent of the electricity sold in the United States.

Ricardo forms company to commercialize cryogenic split-cycle engine: CryoPower

Green Car Congress

The Ricardo CryoPower split-cycle engine concept redefines the processes of internal combustion to enable significantly improved internal thermal efficiency in comparison with today’s state-of-the-art engines. The compression process is carried out isothermally, cooled via the injection of a small amount of liquid nitrogen.
