The shift of renewable energy from times of oversupply to those of over-demand is maximizing the demand for long-term storage.

FREMONT, CA: The diffusion of renewable energy into the electric grid expands generation from low-carbon energy sources, sustainable, which dramatically increases the demand for energy storage at various scales for constant grid security, power supply, and cost mitigation for ratepayers. Long-duration and long-term energy storage can integrate the intermittency of renewable sources and alleviate the uncertainties incurred by decreased fossil-fuel baseload generation. An article published in Greentech Media talks about some tangible advances for long-duration energy storage. Here are a few long-duration energy storages with the value-added technologies.

Safety has always been a concern for the industry. Several examples of fire and explosion are seen where operators experience combustible events at their plants. Industries have embraced the alternatives to lithium-ion. Flow battery keeps the safety benefits up for years and has a good enough reason to stay in the industry. The renewed emphasis on safe storage facilities hence creates an opening, which upstart companies take benefit of. 

Compressed air energy storage helps in managing the supply of electricity in the grid. Compressed air energy storage comprises converting electrical energy into high-pressure compressed air that can be released later to fuel a turbine generator to generate electricity. This signifies that it can work alongside technologies like wind turbines to offer and store electricity 24/7.

Various energy storage strategies subsist, with electrochemical, thermal, and mechanical methods either currently being implemented or under development. Enduring storage may further bolster chemical fuels, while progressing reduction in renewable expenses along with lessening of excess wind and solar generation, creating affordable electricity. This will, in turn, provide an opportunity for transforming renewable power to chemicals or fuel when integrating hydrogen with sequestrated or recycled carbon dioxide.
