As renewable energy technologies like wind and solar power become more prevalent, the need for large-scale electricity storage becomes increasingly important. One of the biggest challenges of these technologies is their intermittency; the power they generate is dependent on the weather and time of day, which means it can't always be used when it's needed. To address this, researchers and companies are developing new innovations in grid-scale electricity storage that can last for an entire season.
One of the most promising approaches is called flow battery technology. Flow batteries store energy in a liquid electrolyte, which is pumped through an electrochemical cell to generate electricity. These batteries can be charged and discharged repeatedly without degradation, and their capacity can be easily increased by adding more electrolyte. This makes them ideal for large-scale energy storage applications. Recently, researchers at Harvard University developed a flow battery that can operate for more than a decade with minimal maintenance, and has the potential to store renewable energy on a massive scale.
