Exploring electrolysis for energy storage

(Kyushu University, I2CNER) A research team at Kyushu University's International Institute for Carbon-Neutral Energy Research (I2CNER) developed a flow-type polymer electrolyte cell for power storage. The cell reduces oxalic acid (OX) to glycolic acid, which has a higher volumetric energy-storage capacity than hydrogen gas. Newly fabricated TiO2 cathode enhanced the speed and efficiency of OX reduction. This competitive energy-storage device could be used to balance out the fluctuations in renew
