U of Melbourne team demonstrates direct hydrogen production from air; direct air electrolysis (DAE)

Green Car Congress

Researchers at the University of Melbourne (Australia) have demonstrated a method of direct hydrogen production from air— in situ capture of freshwater from the atmosphere using hygroscopic electrolyte and subsequent electrolysis powered by solar or wind with a current density up to 574 mA cm ?2.

Opinion: Reinventing fuel-based power for a more secure and resilient grid

Green Car Congress

It is, however, a challenge that is being made all the greater as we continue to decentralize power generation with more distributed, variable and inflexible sources, such as wind and solar. Increasingly, wind and solar are replacing fossil fuels as our principle source of energy.

IPG to demo Flameless Ceramic Turbine for clean, off-grid power in EV charging

Green Car Congress

Grid access and capacity issues, as well as the infeasibility of on-site solar and wind, is a barrier for EV charging in many locations. Not only can IPG’s technology deliver low-emission, pollutant-free energy on today’s cleaner fuels. —IPG CEO Toby Gill.

IRENA report finds renewable power costs at parity or below fossil fuels in many parts of world

Green Car Congress

The report, “ Renewable Power Generation Costs in 2014 ”, concludes that biomass, hydropower, geothermal and onshore wind are all competitive with or cheaper than coal, oil and gas-fired power stations, even without financial support and despite falling oil prices. Report highlights include: Cape Wind’s troubles. —Adnan Z.
