So, What Exactly Is Long-Duration Energy Storage?

The title of this post is the same as that of this article on Greentech Media.

This is the sub-title.

Everyone’s talking about it, and Californians are buying in. Here’s what you need to know about this emerging grid sector.

It describes what California is doing and the sector, with particular reference to Hydrostor, Form Energy and Highview Power.

The article finishes with a section entitled What’s The Catch?

This is the first two paragraphs.

The obvious barrier to a thriving long-duration storage industry is convincing generally conservative power plant customers that emerging technologies quite unlike anything the grid currently uses are safe bets for decades of operation.

Lab tests can reduce the risk, but nothing beats operational, megawatt-scale installations for proving that something works. That’s why the Form deal with Great River Energy is so crucial, as are early projects by Highview Power and Hydrostor. The big exception to technology risk is pumped hydro, which has been used at scale for decades. Those projects grapple instead with high capital expense and environmental concerns.

The article is a must-read and hopefully, this and more articles like it, will convince conservative energy company owners, regulators and governments, that long duration energy storage is the missing link between renewable power and electricity consumers.

At least, the current UK Government has backed two of the most promising British long duration energy storage companies; Gravitricity and Highview Power.
