The Mysterious 150-hour Battery That Can Guarantee Renewables Output During Extreme Weather
The title of this post, is the same as that of this article on Recharge.
The article talks starts by talking about Form Energy, who I wrote about in 150 Hours Of Storage? Company Says That’s True To Form.
As to Form Energy’s technology, they say that there is speculation, that sulphur is the main ingredient.
The article, then lists other technologies, that are under development to store energy.
- Zinc8 – The headline on their web-site is Zinc8 is redefining long-term energy storage.
- Highview Power – Who seem to be close to commercial operation.
- Siemens Gamesa ETES – Hot rock storage now under test in Hamburg.
- Stiesdal Storage Technology GridScale – Under development
- Malta’s molten salt system – See Malta Energy Storage System Is Looking Forward To First Pilot
There’s certainly no lack of entrants for the contest to provide long-term energy storage.
The article is a summary of both Form Energy and the others in the field.

Maybe the sulphur is used as a phase change medium (PCM). It melts at 115 degrees Celsius, so steam at minimal pressure would do the trick for charging, and the output could be steam to drive a turbine. Once charged, the core will stay at 115 until the whole medium has gone solid again. Sulphur is cheap, and an underground store could hold a massive amount of heat as sulphur has a high latent heat.
