Sage enters land use agreement to build first Geopressured Geothermal System

ThinkGeoEnergy

“Once operational, our EarthStore facility in Christine will be the first geothermal energy storage system to store potential energy deep in the earth and supply electrons to a power grid,” said Cindy Taff, CEO of Sage Geosystems. In addition, water losses are targeted to be less than 2 percent.

How Siemens Energy Is Targeting the US Green Hydrogen Opportunity

GreenTechMedia

Green hydrogen is both an untested and a potentially vital way for renewable-energy-powered grids to store their intermittent power for later use, not just for hours at a time, but for days, weeks or even seasons ahead. That project envisions turning excess solar into hydrogen to augment the natural-gas supply for FPL’s 1.75-gigawatt

Clean energy and markets are the solution (not scapegoat) for California’s blackouts

GreenBiz

Forced outages are a tool of last resort, employed in circumstances of incredible stress to the grid and done to protect against more widespread outages. Record heat for several days across parts of the state strained the power grid so much that it started rationing electricity, for the first time in almost 20 years.

Dominion Targets 24GW of Renewables and Storage in Move Toward Virginia’s Clean Energy Goals

GreenTechMedia

Under the law, Dominion Virginia and the smaller Appalachian Power Co. must supply 30 percent of their power from renewables by 2030, and Dominion must close all carbon-emitting power plants by 2045. Major boosts for solar, offshore wind and energy storage. Retreat from natural gas not enough for environmental advocates.

Report Cites Planning, Market Failures at Root of California’s Rolling Blackouts

GreenTechMedia

California’s two days of rolling blackouts in August were the result of disconnects between its existing grid reliability constructs and the needs of an increasingly solar-powered grid, and its failure to prepare for a Western U.S.-wide wide heatwave that undermined its reliance on out-of-state resources.

How to Build a Green Hydrogen Economy for the US West

GreenTechMedia

Out in Utah, a coal-fired power plant supplying electricity to Los Angeles is being outfitted with natural-gas-fired turbines that will eventually be able to run on hydrogen, created via electrolysis with wind and solar power and stored in massive underground caverns for use when that clean energy isn’t available for the grid.
