Solar is now the cheapest source of bulk electricity in most sunny countries. We don’t need a technology breakthrough or subsidies to achieve massive adoption — just a grid connection and/or permission to sell electricity

Oct 2020: We’ll see solar & wind farms with capacity much larger than the grid connection, some with batteries…Solar curtailment is a feature not a bug. Solar’s probably the easiest source of generation to curtail quickly, so can really contribute to grid stability. And sometimes curtailment is a price worth paying for using a grid connection more fully. Hydrogen is …

Road to lowest cost grid is paved with distributed solar+storage: 247 GW of local rooftop and community solar and 160 GW of local energy storage is most cost-effective path. Local solar can power 25% of US homes

What would the grid look like, and cost, if we stopped ignoring the benefits of DERs and optimized the integration of these resources through a better modeling process? We found that when you use better planning models and scale both local solar and storage, as well as utility-scale solar and wind, you maximize cost savings and unlock the path to …

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 …
