MIT Researchers Unveil Breakthrough in Liquid Air Energy Storage
MIT and Norwegian scientists have demonstrated that liquid air energy storage (LAES) offers a cost-effective, scalable, and clean solution for storing renewable energy, potentially outperforming lithium-ion batteries and pumped hydro systems.
A collaborative study by MIT and the Norwegian University of Science and Technology reveals that liquid air energy storage (LAES) is a promising method for storing surplus renewable energy. The process involves liquefying air when energy supply exceeds demand and later reheating it to generate electricity, all without the need for rare materials or specific geographical conditions. Economic analyses indicate that LAES can deliver energy at approximately $60 per megawatt-hour, making it more affordable than traditional storage methods like lithium-ion batteries and pumped hydro. The research highlights regions such as Texas and Florida as optimal markets for LAES deployment, suggesting that this technology could play a pivotal role in advancing a sustainable energy future.
