While clean energy is not a new area for Alphabet’s X, the moonshot division has previously only focused on energy creation. With a new “exploration” called Malta, Alphabet is now looking at cost-effective energy storage solutions.

“Explorations” are X’s “early-stage attempts to investigate new moonshots.” Energy storage is increasingly falling into that category as companies like Tesla are building battery-centered solutions to capture energy from renewable resources.
X is instead “developing a thermal storage system that uses salt to store renewable energy at scale.” Malta is specifically tackling the “mismatch” between the abundance of renewable energy from wind and solar and the lack of cost-effective technologies to store it, especially during peak power usage:
If there’s more energy produced than the electric grid needs, the capacity of wind and solar farms is simply wasted.
With no clean, cost-effective technology for storing renewable energy to serve these peaks, the amount of renewable energy the grid can handle could be capped, and the growth of renewable energy over the next decade could stagnate.
Malta’s solution is to contain just captured electricity as thermal energy. The work behind it comes from Nobel prize-winning Stanford physics professor Robert Laughlin who created as “theoretical system that stores electricity as heat (in high temperature molten salt) and cold (in a low temperature liquid similar to the antifreeze you have in your car).”
