Ongoing innovation: electrolysis, hydrogen and oxygen creation from seawater and sun

At Smithsonian.com  Could Giant “Solar Rigs” Floating On the Ocean Convert Seawater To Hydrogen Fuel?  Scientists at Columbia University have designed a device that could make the process economically viable (Courtesy Flickr user Austin Valley) By Randy Rieland SMITHSONIAN.COM  JANUARY 11, 2018  Usually, when we think about energy production at sea, we imagine giant oil rigs, or perhaps rows of towering wind turbines.  Recently, though, …

Natural gas is 30% of US energy consumption. Home heating, commercial usage, and industry natural gas usage is greater than power plants

Single-cycle gas turbines generally convert the heat energy from combustion into electricity at efficiencies of 35 to 40 percent. Higher efficiencies of 50 percent or more are possible in natural gas “combined-cycle” (NGCC) plants. NGCC plants first use the combustion gases to drive a gas turbine, after which the hot exhaust from the gas turbine is used to boil water into …

Making hydrogen from curtailed wind and solar energy

December 16th, 2017 by Steve Hanley on Clean Technica: SoCalGas Partners With UC Irvine To Design “Advanced Energy Community” For you renewable energy fans out there, count this as a “half a loaf is better than none” story. Southern California Gas is partnering with researchers at the University of California Irvine’s Advanced Power & Energy Program to design an “Advanced Energy Community” in …
