Andy from GENI gives a short presentation about energy storage technologies and how renewable energies are becoming more and more of an important aspect of today's energy grid. But with the fluctuating output of solar and wind energies, new ways need to be found to store energy and maintain a safe and reliable energy supply.
Researchers at the Massachusetts Institute of Technology (MIT) have combined a liquid catalyst with photovoltaic cells to achieve a super efficient (nearly 100%) electrolysis.
This becomes a very effective storage system. One obvious extension of this would be the cost-effective storage of daytime solar energy for night-time use. Excess capacity during the day could be stored as hydrogen and oxygen, then used in fuel cells at night when needed.
