RayGen officially opens 4 MW ‘solar hydro’ power plant
Australian energy technology startup RayGen has officially opened a 4 MW solar and long-duration energy storage project in Victoria, describing it as the world’s “highest efficiency PV project” operating at utility scale.
MIT, NREL researchers develop 40%-efficient thermophotovoltaic cell for grid-scale thermal batteries
The device is described as a heat engine with no moving parts that is able to produce power from a heat source of between 1,900 to 2,400 C. This concept is known as thermal energy grid storage (TEGS) and consists of a low-cost, grid-scale storage technology that uses thermophotovoltaic cells to convert heat to electricity above 2,000 C.
What’s going on in the world of thermal energy storage?
Can this technology be commercialized? A partnership between Siemens Energy and EnergyNest to develop thermal storage solutions together is the latest development in an industry with lots of potential, but little practical application thus far.
