Shifted stores electricity by combining pumped hydro and compressed air to solve the intermittency of Wind and Solar PV. The solution provides electricity at half the cost of lithium-ion batteries, can be deployed anywhere, and does not rely on critical materials. The system is a perfect fit for wind and solar PV producers, and companies servicing the electricity grid. The team brings 60 years of collective experience from startups, big corporations and academic research at Harvard and Princeton.
