Energy efficiency instead of long-term storage

As more communities plan to eventually rely on 100% renewable energy, the researchers offer a strategy that could guide their paths — one that shifts away from long-duration storage.

“Minimizing long-duration storage is a key element in trying to achieve the target cost-effectively,” said Sammy Houssainy, co-author with William Livingood of a new paper that outlines an approach to 100% renewables. The research paper, “Optimal Strategies for a Cost-Effective and Reliable 100% Renewable Electrical Grid,” appears in the Journal of Renewable and Sustainable Energy.

The researchers considered solar and wind as the source of renewable energy, given that most plans for meeting the 100% target take those into account. They also used the Department of Energy’s EnergyPlus and OpenStudio building energy modeling tools to simulate energy demand, considering such factors as building size, age, and occupancy type. Data from the U.S. Energy Information Administration informed the scientists about the existing building stock characteristics and energy load used by the buildings.
