Weekend Read: Light weight
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.
Gravitricity to deploy prototype underground hydrogen storage system
Gravitricity, an Edinburgh-based storage specialist, aims to develop the first full-scale demonstration of its underground hydrogen storage solution by working with structural engineering contractor VSL Systems UK.
Storing wind and solar with new gravity-based system
Scottish start-up Gravitricity is planning a project to store surplus power from renewables at Port of Leith. A 250 kW, grid-connected prototype facility will have its ability to stabilize the network tested. The system involves a 16m rig over a 150-1500m shaft.
