Energy Storage

Duke is planning to construct or acquire up to 1.1GW of renewable energy generation, as well as up to 1.3GW of non-intermittent generation, like natural gas combustion turbines, combined-cycle units and stand-alone battery storage.

Southern California Gas Company is submitting an application to build a 10 to 20GW electrolyzer and 25 to 35GW of new and curtailed wind and solar, along with 2GW of energy storage, to deliver green hydrogen to the Los Angeles Basin.

The Moss Landing Energy Storage Facility Phase II set off fire alarms that activated a fault water suppression system, which – again – set off a cascading set of events that resulted in roughly ten battery packs melting down.

Also on the rise: Oregon-based Powin Energy announced major supply deals covering a 5.8GWh pipeline of energy storage projects in the US and Taiwan. Trade groups raise concerns over interconnection queues. CleanCapital acquires a 39-project, 65.3MW portfolio of solar assets spanning 12 states. Enphase Energy enters agreement to participate in Swell Energy’s virtual power plant (VPP) program in Hawaii, New York, and California. First in the nation green bank surpasses $2 million total investment. PECO releases RFP seeking Pennsylvania solar energy credits. A look at mounting systems for PV on metal roofs.

Golden Fields Solar will be constructed with union labor using a Project Labor Agreement and will include pollinator-friendly habitats throughout the project site.

Since July 2011, the nation’s first Green Bank mobilized $288.4 million in public dollars to attract $1.85 billion in private investment, a leverage ratio of $7.40 for every $1.

The US battery specialist has signed framework agreements with four developers to deliver systems for multiple projects.

Also on the rise: Solar growth occurred despite more than a year of price increases. Interconnection delays and costs plague utility-scale developers. Affordable hydrogen-based system for seasonal energy storage could be achieved at a hydrogen price lower than $3. California PUC raises renewable energy target. Impending 3G shutdown may affect inverters: there’s an app for that.

Winter storm Uri that brought a deep freeze to Texas is also bringing insight into grid vulnerabilities, the need for more renewables, and the potential of solar-plus-storage.

Researchers from the United States have investigated how fuel cells and electrolyzers may be able to operate under intermittent availability provided by both wind and solar and have found that an affordable hydrogen-based system for seasonal energy storage could be achieved at a hydrogen price lower than $3, produced from inexpensive renewable electricity at $0.02/kWh.
