How Good Is ‘Freezing Air’ The Solution For Electricity?

The title of this post is the same as that for this article on Energy News 24.

The article discusses Highview Power’s proposed 400 MWh installation in Vermont, where they are installing lots of renewable power sources and need a way to store the energy, which is partly wasted.

Read the article and especially the last sentence.

Vice President Jason Burwen Energy Storage Association said the capacity of the plant would be “on par with today’s largest grid energy storage projects under construction.” He said it would be the equivalent electricity needed “to power maybe 50,000 homes for eight hours.”

Are the British coming?

The Highview Power system to me is a blindingly obvious simple idea, based on proven technology, that has been used for many decades. Add in clever computing technology to control it and blend it with renewable energy and every wind or solar farm, tidal power station and sizeable town or city should have one, where there is a site the size of a football pitch.

Could Modern Energy Systems Have A Secondary Role?

Close to where I live is a small heat and power system, that I wrote about in The Bunhill Energy Centre.

I first went over the centre during Open House.

Several of these modern systems are very good demonstrations of the principles of maths, physics and engineering.

So do these innovative energy systems do their bit in educating the next generation of scientists and engineers?

Some of the modern systems, that are in development like Highview Power’s energy storage using liquid air would be ideal for a secondary education role!

Most too, are very safe, as there are no dangerous processes or substances.

And in the next few years, there will be more systems all over the country and many in the hearts of towns and cities. Some schools, colleges and especially universities, will have their own innovative energy sources.

Liverpool University already has a system, which is described here.

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.

Gore Street Contracts NEC For 100 MW Of Storage

The title of this post is the same as that of this article on the Solar Power Portal.

This is the introductory paragraph.

Gore Street Energy Storage Fund has awarded NEC Energy Solutions both EPC and long-term O&M contracts for 100MW of storage in Northern Ireland.

What I find most comforting, is the matter-of-fact tone of the article.

Although, the author does seem to think that MW and MWh are the same, when in fact MW is used to define the rate of energy used or transferred and MWh the quantity.

If you use one MW for an hour, that is one MWh.

Gore Street appear to have needed two 50 MW energy storage systems for Drumkee and Mullavilly in Northern Ireland to back up a solar farm investment.

And they appear to have just ordered them off the shelf from NEC, in much the way, an individual might buy a Tesla Powerwall for their house.

According to this article on OVO Energy, the average European house uses 3,600 kWh per year.As there are 8760 hours in a year, the average consumption for a year is 0.4 kW per hour.

So if we assume that these two energy storage systems can deliver 50 MW for an hour, the following can be said.

  • The total capacity of each system is 50 MWh.
  • Each system can supply  125,000 houses for an hour or 25,000 houses for five hours.
  • As each housing unit has an average occupancy of 2.66 people, this means that a 50 MWh battery could supply a town of 66,500 people, for five hours.

Note that Lowestoft in Suffolk has a population of 71,000.

These batteries are not small.

Trump And Flight PS572

What puzzles me about all this is Trump’s reaction.

If he were true to his past persona, he would be very much angrier and vowing vengeance, but his reaction seems almost calm and very measured.

Perhaps, he knows for certain, that it was a tragic accident. After all the UK, US, Canada and Ukraine seem to be saying similar things.

Someone or something, seems to have got Trump to see sense!

Melania, Justin, Boris, Emmanuel, Dominic or Angela? Or was it the Italian guy, who does his hair?

Walking Between Blackfriars And Hungerford Railway Bridges

These pictures were taken as I walked between Blackfriars and Hungerford railway bridges.

I was walking along the South Bank of the Thames.

The Times Had A Hydrogen Saturday

The Times had a feature on Saturday about converting our gas grid to hydrogen and especially about using hydrogen boilers in our homes.

I believe that perhaps in ten years, our gas grid will be full of hydrogen and our central heating boilers will be powered by hydrogen.

The carbon emissions saved with be massive

I don’t know about cooking, but my Michelin-starred Scottish friend and chef, says that we’ll all cook on an electric induction hob.

A Large Collateral Benefit?

I think there will be a large collateral benefit.

At present there are only two feasible methods to power a vehicle without producing carbon emissions; battery or hydrogen.

  • Battery vehicles need to be recharged and we need an enormous number of charging stations.
  • Hydrogen vehicles need to be filled up from a hydrogen filling station.

It should be noted that the current Hyundai ix35 FCEV has a range of 369 miles on hydrogen.

But as you have a hydrogen gas supply to your house, could you fit a compressor in your garage to pump up your car’s hydrogen tank, when it needs it?

The technology is well-proven.

The only problem, that I can see, is that how will the Government tax it?

The future’s not orange it’s hydrogen.

Are The British Going To Rescue Vermont?

This article on the Scientific American is entitled To Store Renewable Energy, Try Freezing Air.

This is the sub-title of the article.

Such energy storage technology could help relieve congested transmission lines in places like Vermont.

It certainly is a must read, about the possibilities of energy storage and Highview Power in particular.

Qassem Soleimani

Yesterday, The Times had an article, which was entitled Rising stars: Twenty faces to look out for in 2020.

I read the article on my phone and it was a good read.

One of those people mentioned was Qassem Soleimani

He was certainly somebody to look out for and I wondered what he would get up to next!

I don’t have to wonder anymore.

This article on the BBC is entitled Qasem Soleimani: US kills Iran Quds Force leader, Pentagon confirms.

Apparently, the killing was on the direct orders of President Trump.

He obviously hasn’t read about the Greek Monster, where when Heracles cut off one head another appeared.

I certainly fear for the hostages caught up in this Iranian mess!

Trump is staggering blindly towards a disaster!

A First For Christmas Day

I am reading today’s copy of The Times on my computer.

I’ve never read a newspaper published on Christmas Day before.

They’ve even published a set of their puzzles as an alternative to Happy-Clappy Television

But I’m sure other papers have published digital editions.
