Sodium Energy Storage-Key Clean Energy for the Future World

Abstract

Long-term energy storage is a bottleneck in the large-scale development of renewable energy, addressing the mismatch between renewable energy utilization and electricity demand. Sodium exhibits significant advantages in energy density, storage cost, and energy release efficiency, enabling large-scale storage and convenient transportation. Its production and usage processes do not generate greenhouse gases, making it a viable substitute for fossil fuels to meet the seasonal adjustment needs of renewable energy. The article designs a device and method for sodium combustion in steam, efficiently releasing energy and producing hydrogen. Establishing a sodium-centered energy system interconnects renewable energy, electricity, and hydrogen, supporting the decoupling of terminal energy consumption and carbon emissions. This meets the growing energy demands for human economic development while avoiding environmental harm caused by carbon dioxide emissions contributing to global climate change. Such a system holds immense potential for applications and is in urgent demand.
