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. 100% wind and solar is not feasible on its own.

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.

Study links air pollution and cyclone intensity in Arabian Sea; suggested solutions include diesel filters and two-stroke engines running on LPG fuel

Green Car Congress

Pollution is making Arabian Sea cyclones more intense, according to a study in the journal Nature. Historically, prevailing wind shear patterns prohibit cyclones in the Arabian Sea from becoming major storms. Gonu produced category 5-strength winds in excess of 250 kilometers per hour (156 miles per hour).

EPA finalizes Cross-State Air Pollution Rule (Transport Rule)

Green Car Congress

The US Environmental Protection Agency (EPA) has finalized the new Cross-State Air Pollution Rule (CSAPR) (also called the Transport Rule). Carried long distances across the country by wind and weather, power plant emissions of sulfur dioxide (SO 2 ) and nitrogen oxide (NO x ) continually travel across state lines. Source: EPA.
