An MIT concept would connect deep-water wind turbines to concrete spheres at the seafloor that would take advantage of hydrostatic pressure to store energy.
A researcher offers a new possibility for grid-scale energy storage – a lithium-polysulfide flow battery that could be cheap and long-lasting.
The all-renewables future will require energy storage. Here we explore both current possibilities and technologies that might one day be practical.
A pumped hydro project at a former iron ore mine near Joshua Tree National Park is touted as a way to get more renewable energy on the grid.
Blending hydrogen into natural gas pipelines could be a way to increase output from renewable energy production facilities, a U.S.-commissioned report says.
A wind turbine without a generator? A Wyoming company says not only can it produce energy, but it can also store it.
Researchers say a new technique to scale up fabrication of graphene micro-supercapacitors could have them replacing batteries, with vastly faster charging.
