According to the Institution of Mechanical Engineers in London, UK, liquid air energy is now able to compete with batteries and hydrogen through the process of stored excess energy, generated from renewables at places like the CryoEnergy System (CES).
In 2011, it was common knowledge that key renewables could produce a limited amount of intermittent power. This left the United States struggling to store excess energy, looking at "solar and wind providing only a modest percentage of future U.S. power."
Former Energy Secretary, James Schlesinger, and former senior energy program adviser for Science Applications International Corporation and Senior Energy Advisor at MISI and a consultant in energy, technology, and management, Robert L. Hirsch, were published at Yale University article as saying to the Washington Post, "Why are we ignoring things we know? We know that the sun doesn’t always shine and that the wind doesn’t always blow.”
