Compressed-air energy storage A pressurized air tank used to start a diesel generator set in Paris Metro Compressed-air-energy storage (CAES) is a way to store energy for later use using compressed air. At a utility scale,
Gases like compressed air increase in pressure as temperatures increase, meaning the heated wells could potentially store more energy, according to Taleghani. When electricity is needed, the heated, compressed air is released, driving a turbine to produce power.
Repurposing depleted oil and gas wells may also help mitigate potential environmental impacts of abandoned wells and potentially provide new job opportunities in areas with rich energy industry traditions, the researchers said. In Pennsylvania alone, regulators estimate there are hundreds of thousands of orphaned and abandoned wells.
Energy storage options like CAES are particularly important in the transition to clean energy, according to the researchers, because they help address the intermittent nature of renewable sources. By storing excess renewable energy and releasing it when needed, energy storage contributes to grid stability and reliability.
The researchers recently published their findings in the Journal of Energy Storage. CAES plants compress air and store it underground when energy demand is low and then extract the air to create electricity when demand is high. But startup costs currently limit commercial development of these projects, the scientists said.
