Japan team evaluates battery-assisted low-cost hydrogen production from solar energy

Green Car Congress

Researchers from Japan’s NIMS (National Institute for Materials Science), the University of Tokyo and Hiroshima University have jointly conducted a techno-economic analysis for hydrogen production from photovoltaic power generation (PV) utilizing a battery-assisted electrolyzer. This approximately converts to US$1.92 to US$3.00/kg

Expert panel report finds achieving 1M plug-in vehicles in US by 2015 would require concentrated action to overcome barriers

Green Car Congress

A new study sponsored by Indiana University concludes that President Obama’s vision of one million plug-in electric vehicles (PEVs) on US roads by 2015 will require concentrated efforts action from all stakeholders— the auto industry, federal government, the scientific community, and consumers—to be realized.

Why the Next Microgrids Will Be Well Connected

Cars That Think

The winds had barely died down when electric-power specialists and others began calling for a radical overhaul of Puerto Rico’s electricity networks, one that would emphasize renewable energy, distributed generation, and, critically, microgrids. A microgrid is like a miniaturized, tightly controlled version of a power grid.

Opinion: Debunking the mythsWhy fuel cell electric vehicles (FCEVs) are viable for the mass market

Green Car Congress

Despite the recent progress, a number of myths around the use, power efficiency and cost of fuel cells still exist. Hydrogen is the most abundant element in the Universe but, on earth, it must normally be extracted from water or organic compounds. The cost of making fuel cell vehicles has recently dropped dramatically.
