In order to implement the new climate regime and transition to a carbon-neutral society, it is essential to develop an economical large-capacity energy storage system (ESS) that can alleviate the volatility of renewable energy and secure the flexibility of the power system. Blue Battery is an economical, eco-friendly, large-capacity, future-oriented ESS technology that can solve the problem of renewable energy curtailment. Blue Battery uses seawater to separate salts into acids and bases, stores energy, and then produces electricity through a neutralization reaction between acids and bases. To verify the design, assembly, and performance of the Blue Battery, pH durability and long-term performance stability must be examined. Based on the performance evaluation, the energy density was measured to be approximately 3.0 Wh/L with the power density over 3.0 W/m2.
