The adoption of renewable energy on a large scale by utilities has been on hold, waiting for a breakthrough to solve the biggest problem for large-scale use: how to store energy produced by wind and solar power for those times when the wind doesn’t blow and the sun doesn’t shine? Without the ability to store excess energy from variable renewable generators during peak production times, utilities have been unable to deploy them on a commercial, financially viable scale. Grid-sized batteries have been tried, but they are expensive and have a short life span.

Now, two new companies have come up with distinct innovations that might resolve this energy storage issue. SustainX uses a patented foamy material to maintain an even temperature for compressed-air storage of renewable energy. LightSail has developed water-cooled compressed air storage systems. In a sign that these technologies may be answers to solving the renewable energy storage problem, the companies have attracted significant support. SustainX has received $43 million from the Department of Defense and the National Science Foundation, as well as funds from venture capital firms Polaris Partners and RockPort. LightSail has raised $42 million from Bill Gates and other investors. So promising are these tech innovations that the industry’s revenue is projected to rise from $37 million last year to $1.6 billion by 2016. That’s a powerful bottom line argument for renewably sourced power.
