Looking to get in a hybrid for cheap? Used Toyota Prius 1.5 HSD 2004-2009 Review

Green Car Congress

I knew I wanted something for her that was cheap to maintain, had a reliable automatic transmission, came with cruise control, AC. On the way there, I made a pit stop at a gas station to buy a bottle of champagne as a gift, hoping to start out a conversation with a stranger on the right foot. It was time to buy our first car.

Researchers use chemical looping process to produce hydrogen from hydrogen sulfide gas

Green Car Congress

Researchers at The Ohio State University have used a chemical looping process to produce hydrogen from hydrogen sulfide gas—commonly called “sewer gas”. Hydrogen sulfide is emitted from manure piles and sewer pipes and is a key byproduct of industrial activities including refining oil and gas, producing paper and mining.

IIASA study proposes solid air hydrogen liquefaction as efficient addition to hydrogen liquefaction supply chain

Green Car Congress

At standard temperature and pressure, air is a gas, but under certain conditions, it can become a liquid or solid. The hydrogen is liquefied where electricity is cheap. —Julian Hunt Resources Hunt, J., One option is to liquefy hydrogen, which requires cooling to 20 Kelvin (-253 °C). Montanari, P., Schneider, P.,

PNNL team develops electrolyte for high-voltage sodium-ion battery with extended longevity

Green Car Congress

Cheap and abundant, sodium is a promising candidate for new battery technology. We also measured the production of gas vapor at the cathode. We found very minimal gas production. However, the limited performance of sodium-ion batteries has hindered large-scale application. —Phung Le.
