Researchers in Japan propose a more efficient method to reduce radioactive waste; fast reactor system shortens the lifetime of LLFPs

Green Car Congress

A team of scientists at Tokyo Institute of Technology (Tokyo Tech) working in collaboration with Tohoku University, Tokyo City University and the Japan Atomic Energy Agency has proposed a novel, more efficient method to reduce radioactive waste. The team showed that support ratios of more than 1.0

Space-based Solar Power: A Great Idea Whose Time May Never Come

Cars That Think

A decade ago we featured a project at the Japan Aerospace Exploration Agency that aimed to launch a 1-gigawatt solar station by 2031. A space solar project would “waste capital that could be better spent improving less risky ways to shore up renewable energy, such as batteries, hydrogen, and grid improvements.”

Hydrogen Production from Waste Tires Using a Catalytic Pyrolysis-Gasification Process

Green Car Congress

A team at the University of Leeds (UK) is investigating hydrogen production from waste tires using a two-stage pyrolysis-gasification reactor and Ni-Mg-Al (1:1:1) catalyst. The generation rate of waste tires is increasing, especially with the continued increase in production of cars and trucks, the authors note.

Startup offers EV firms greener graphite in alternative to China – ET Auto

Baua Electric

It also expects to set up facilities in Korea, Japan and Europe. An alternative energy startup in Malaysia is ready to help electric-vehicle makers source a key ingredient outside of China — using agriculture waste to create graphite. It also expects to set up facilities in Korea, Japan and Europe. this month.

NEC, NEC TOKIN and Tohoku University develop spin-Seebeck thermoelectric device w/ 10x better conversion efficiency

Green Car Congress

Thermoelectric conversion technology that converts energy abandoned as waste heat back to electric power is strongly anticipated to be used for saving energy and reducing greenhouse gas emissions. This is a phenomenon in which a temperature gradient applied in a magnetic material produces a spin current along the temperature gradient.

Old empires could be the key to a new car future – ET Auto

Baua Electric

An alternative to electrolysis is to use organic waste by extracting hydrogen from rotting food or sewage. All three automakers are part of larger business empires — called chaebol in South Korea and keiretsu in Japan. Such facilities could be tacked onto existing gas stations, but needn’t be.

New LLNL membrane bridges operational gap between low- and high-temperature PEM fuel cells; potential for lower cost systems

Green Car Congress

Low-temperature PEM fuel cells that use Nafion are at present being commercialized in fuel cell vehicles, but these cells can operate only at relatively low temperatures and high hydration levels; therefore, they require humidified inlet streams and large radiators to dissipate waste heat.
