long-duration energy storage

Hyme Energy has awarded Semco Maritime an engineering, procurement, and construction (EPC) contract for services for the 1.6 MWh Molten Salts Storage (MOSS) Project in Esbjerg, Denmark. The long-duration energy storage plant will charge from the grid and be used to demonstrate and test the molten hydroxide storage technology in a practical setting.

When it comes to gravity batteries, pumped-hydro storage is the gold standard, but its cost and topography-specific limitations are driving innovations ranging from freight-train braking to super-dense liquids. We consider whether any of the new technologies can punch above their weight.

Long-duration energy storage (LDES) is essential for decarbonizing the grid but gigawatt-hour scale systems continue to be tricky for companies with big ideas. Here are some of the latest innovations across a flourishing array of new – and old – ideas.

The deployment of a vanadium flow battery at a fire station run by Native Americans illustrates the role that the energy storage technology can play in ensuring that nobody is disadvantaged by the shift away from fossil fuels.

Chinese scientists have analyzed reports of thermal issues with vanadium redox flow batteries (VRFB) and existing thermal management methods. They say the operating temperature should be maintained in the range of 10 C to 40 C to ensure VRFBs with high efficiency, weak side reactions, high electrolyte stability, and low crossover.

Edinburgh-based energy storage solutions specialist StorTera has developed a long-duration, energy-dense, lithium-sulfur-based single liquid flow battery (SLIQ). The tech is said to last for 30 years with minimal degradation.

This year has witnessed upheaval in the global energy system as inflation, geopolitical conflict, and the reality of a changing climate continue to drive the transition to cleaner energy. Next year, these trends are likely to continue and accelerate as renewable energy adoption continues to grow and the inextricable link between energy security and national security is increasingly recognized. Alan Greenshields, of US-based iron-salt flow battery maker ESS Inc, offers four predictions for 2023.

Southwest Research Institute (SwRI) has commissioned a first-of-its-kind pilot plant pumped heat energy storage demonstration facility with tech from US startup Malta. Its 10-150+ hour energy storage technology is said to be applicable in a range of grid-scale applications.

A report from Wood Mackenzie predicts lithium-iron-phosphate will overtake lithium-manganese-cobalt-oxide as the dominant stationary energy storage chemistry within the decade.
