Researchers developing DC micro smart grid for charging EV fleets; Li-ion, redox flow batteries and renewables

Green Car Congress

The aim of charge@work is to design a micro smart grid (MSG) capable of supplying the EV fleet with electricity produced exclusively from renewable sources. A 30-meter-tall wind turbine delivers 10 kW. Since it operates on a vertical rather than a horizontal axis, it does not have to be oriented to wind direction. — Dipl.-Ing

Panasonic to begin mass-production of long-life Li-ion battery system for solar-powered homes in Europe

Green Car Congress

In Germany and other European countries, governments are cutting purchase prices for solar power in order to rein in the expansion of solar power generation, which led to increases in energy prices, Panasonic noted. Through field tests in Germany, Panasonic is ready to mass-produce the lithium-ion battery system.

Shipping industry eyeing hydrogen fuel cells as possible pathway to emissions reduction; work by Germanischer Lloyd and DNV

Green Car Congress

The GL design concept proposes using wind energy to produce LH 2. A 500 MW wind farm could produce up to 10,000 tonnes of liquid hydrogen from surplus power it is unable to feed into the gird. The ship’s electric propulsion system therefore consume fuel cell power equivalently to power provided by the main generators.

Lean Software, Power Electronics, and the Return of Optical Storage

Cars That Think

Goldstein: Everything you need to know about the EV transition can be yours for the low, low price of free. As I say, these power adapters that convert AC to DC, they get more efficient. Your power supplies in your computer get more efficient, and your power supplies in your grid center. And it bundles up.
