Prowling for Solutions To Unleash Renewable Energy

The title of this post, is the same as this article on Toolbox.

It is a good summary of the best methods of storing renewable energy without using chemical batteries.

Gravitricity, Energy Vault and Highview Power are all mentioned.

This last paragraph, explains some of the philosophy behind Vermont looking seriously at Highview Power.

Vermont may well be tempted by liquid air energy storage because of its flexibility — simply requiring a two-acre site anywhere. One possible location could be near an abandoned power station. That’s a beautiful solution because the transmission lines that once transported the electricity from the plant are built and ready to use in the renewable era.

Note that a two-acre site is slightly smaller than a football pitch.

It is rather elegant to replace a coal- or gas-fired power-station with an environmentally-friendly energy storage system on the same site, which effectively does the same job of providing energy.

The article doesn’t mention employment, but surely many of the existing workforce can be easily retrained for the new technology.

Energy Vault Receives $110 Million From SoftBank For Gravity-Assisted Power Storage

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

Energy Vault is a company, that is developing gravity-assisted power storage.

You don’t invest £110million in a company, even if you are as rich as Softbank, unless you are certain, that you’ll get a return!

So I suspect Energy Vault may have a working system for storing energy

Read the article and see what your think! It also links to a video.

This is an interesting quote from the company.

We knew we needed to be around three to four cents levelized cost per kWh ($30 – $40 per MWh) to add to PV or wind in order to be competitive below fossil.  This took a lot of innovation.

I shall be following the company.
