Hardware to Save a Planet

In this episode of Hardware to Save a Planet, host Dylan Garrett sits down with Curtis VanWalleghem, Co-Founder and CEO of Hydrostor, to discuss how compressed air energy storage can revolutionize renewable energy. Hydrostor's innovative underground caverns store air and water to provide long-duration, cost-effective energy storage—solving the intermittency challenge in renewable grids. The conversation dives into engineering breakthroughs, economic advantages over batteries, and the policy shifts needed to enable 100% renewable energy.
