Researchers at the Pacific Northwest National Laboratory (PNNL) are exploring innovative ways to store and release clean hydrogen energy, inspired by the chemistry of baking soda. As global demand for zero-carbon energy sources increases, hydrogen presents a promising solution due to its abundance and non-toxic properties. Current hydrogen storage methods are costly and inefficient, prompting PNNL to investigate the bicarbonate-formate cycle—a mild, non-toxic, and environmentally friendly method using formate ions to carry hydrogen in water. This approach could enable energy storage over long durations, addressing seasonal demand fluctuations in renewable energy sources. PNNL’s research is part of the Department of Energy’s Hydrogen Shot initiative, which aims to reduce hydrogen production costs significantly. The bicarbonate-formate cycle could become a feasible option for hydrogen storage, functioning at moderate temperatures and low pressures compared to traditional methods like liquid hydrogen. However, challenges remain in enhancing the cycle’s efficiency and scalability. The team is also exploring the use of palladium catalysts to optimize the process. Overall, the baking soda-inspired research is seen as a significant advancement in developing sustainable hydrogen storage solutions, opening possibilities for improved energy infrastructure.
