Ramya Swaminathan is the CEO of Malta Inc, a company that spun out of Google’s moonshot factory in 2018 to work on an energy storage solution using the existing power grid. One thing holding the world back from a transition to clean energy: electricity generated from sources like the sun and wind has to be used right away or it disappears…but one possible answer might be—salt.

This week on How I Built This Lab, Ramya recounts how she got into the renewable energy industry with two previous companies focused on hydropower. She also explains how molten salt and coolant might be better than batteries as a low-cost, long-duration and job-preserving energy storage solution.
