Storing Renewable Energy for a Clean Energy Future

Storing renewable energy at utility scale for availability on demand is a central component of a clean energy future. Various forms of storage, such as pumped hydroelectric energy storage, batteries, thermal energy storage, and others, offer solutions. However, challenges remain, especially in integrating stored energy into the grid and the costs of new storage methods. Government agencies, like the Department of Energy (DOE), are supporting storage technology research and innovation and the Government Accountability Office (GAO) is actively involved in developing energy storage policies. In its evaluation of utility scale energy storage technologies, the GAO points out the need to tackle issues like planning and regulation. On a global scale, the World Bank recognizes the significance of energy storage in moving towards a clean energy future and makes note of the testbed in Morocco, where research efforts are underway to address this. California is leading the way in energy storage, reaching the capacity to store enough electricity to power 6.6 million homes for up to four hours. The State of New Jersey has one of the most ambitious clean energy programs in the nation, with storage targets mandated to achieve 2,000 megawatts (“MW”) of installed energy storage by 2030. Addressing the technology challenges and policy options is crucial for making the most of energy storage and creating a cleaner, more sustainable future.
