Sunrise brief: It’s time to combat utility opposition to solar
Also on the rise: U.S. Army builds further resilience with flow battery pilot project at Fort Carson. Cooling down solar modules by increasing space between panel rows. And more.
U.S. Army builds further resilience with flow battery pilot project at Fort Carson
The redox flow battery dubbed GridStar Flow is intended to help protect the installation during emergency situations.
Semi-solid flow battery tech promises to lower production costs by up to 40%
While still using conventional lithium-ion raw materials, 24M’s technology is said to reduce the number of steps required to manufacture battery cells and thereby the cost by up to 40%. The US company’s SemiSolid design is also said to deliver improved energy density, safety and recyclability.
South Carolina electric co-op pursues batteries and other alternatives to a proposed gas unit
Utility-scale batteries are being pursued by many utilities, the generation and transmission co-op utility said in explaining its decision, while aggregated distributed resources “can be counted on as predictable generation capacity.”
Sunrise brief: Georgia Power proposes to apply $200 rooftop solar interconnection fee to its customers
Also on the rise: Distributed resources to earn compensation from Texas grid operator ERCOT. Vertical solar on high-rise building to produce 58 MWh annually. And more.
Colorado utility agrees to low-income solar program in nearly $100 million settlement
In a settlement agreement with the Environmental Justice Coalition, Xcel Energy agreed to boost equitable access to rooftop solar, community solar, and battery storage. It will set aside $33 million for environmental justice communities and $53 million for community solar.
Distributed resources to earn compensation from Texas grid operator ERCOT
ERCOT’s pilot project, designed in less than a year, will support grid reliability and is expected to be ongoing. Some other grid operators have already launched or announced similar programs.
Non-flammable, graphene-based lithium-ion batteries approaching stationary storage market
Nanotech Energy’s graphene battery uses proprietary electrodes with a thermally stable separator, and non-flammable electrolyte that is said to be inexpensive to manufacture. The technology is said to be superior in terms of safety and competitive in terms of cell performance.
Quinone flow battery for grid-scale renewables storage now close to commercial viability
Startup Quino Energy has raised more than $7.8 million to scale up its quinone redox flow battery technology. Harvard University and University of Cambridge researchers came up with the initial research for the battery design.
Sunrise brief: Proposed regional clean hydrogen hubs to compete for $7 billion in DOE funding
Also on the rise: Renewable PPA price relief from the Inflation Reduction Act may take time. Salient Energy zinc-ion battery passes UL safety testing. And more.
