Improved water splitting method: A green energy innovation
30 Aug 2021 at 1:39pm
Hydrogen is a promising clean energy source with great potential to replace greenhouse gas-emitting fossil fuels. While total water (H2O) splitting is the easiest way to obtain hydrogen (H2), this reaction is slow and not yet commercially feasible. Now, scientists have developed a novel electrocatalyst that significantly improves hydrogen production from water splitting in an energy and cost-efficient way.

Green hydrogen: Focus on the catalyst surface
24 Aug 2021 at 10:53am
Hydrogen produced from renewable energy sources with the help of electric power is deemed a key to the energy transition: It can be used to chemically store wind and solar energy in a CO2-neutral way. Researchers have studied water electrolysis processes on the surface of an iridium oxide catalyst.
How do wind turbines respond to winds, ground motion during earthquakes?
24 Aug 2021 at 9:10am
Wind power has experienced fast growth within China during the past decade, but many wind farms are being built within regions of high seismic activity. Researchers are now exploring the dynamic behaviors of wind turbines subjected to combined wind-earthquake loading. The group discovered that changes in the wind increase and decrease the response amplitude of the wind turbine under weak and strong earthquakes, respectively.
Effect of ?eddy killing? in oceans is no longer a matter of guesswork
19 Aug 2021 at 4:50pm
Applying a new coarse-graining, spatial method of analysis to satellite imagery, scientists provide a direct measure of the impact of wind driven eddy-killing on the kinetic energy of ocean currents -- a continual loss of 50 gigawatts, equivalent to the detonation of a Hiroshima nuclear bomb every 20 minutes, year round.
