Drax Secures £500,000 For Innovative Fuel Cell Carbon Capture Study

The title of this post, is the same as that of an article on the Drax web site, that was published in June 2019.

This is the first paragraph.

Drax Group will explore the feasibility of using molten carbonate fuel cells as a technology for capturing carbon dioxide (CO2) having secured £500,000 of funding from the UK Government.

These objectives are listed.

  • Fuel cell FEED study to assess the feasibility of building a second carbon capture pilot at Drax Power Station will help position the UK as a world leader in the fight against climate change
  • The technology used will produce power at the same time as capturing carbon dioxide from Drax’s flue gases.
  • Neighbouring horticultural site will use the COto improve yields and demonstrate how businesses working together in clusters can deliver climate solutions

I am glad to see, that the Government is supporting initiatives like this.

The Drax Paradox

I have seen strawberries in a supermarket, labelled as coming from a farm at Drax in Yorkshire.

Were they grown using carbon dioxide from the power station?

They probably weren’t labelled as organic, but can you grow organic strawberries in a carbon-dioxide-rich atmosphere and label them as Organic?

Conclusion

I don’t think these and other technologies will lead to any massive revival of coal-fired power stations, as mining coal is a very disruptive and dangerous process compared to extracting gas or growing bio-mass.

But I do think that they are needed for application to the following plants, that produce a lot of carbon dioxide.

  • Gas-fired power stations.
  • Biomass power stations.
  • Cement-making
  • Steel-making

The two last processes are probably the most important, as improvement in renewable energy generation, should make the first two redundant.

The Mathematics Of Fast-Charging Battery Trains Using Third-Rail Electrification

In Vivarail Unveils Fast Charging System For Class 230 Battery Trains, I talked about how Vivarail are proposing to fast-charge their Class 230 trains.

  • The trains are fitted with special high-capacity third rail shoes.
  • Third-rail electrification is laid in stations.
  • The third rail is powered by a bank of bstteries, that are trickle-charged from the mains or perhaps even solar power.
  • When the train connects to the rail, the rail is made live and a fast transfer takes place between third-rail and train.

So how much electricity could be passed to a train during a stop?

The most powerful locomotive in the UK, that can use 750 VDC third-rail electrification is a Class 92 locomotive.

According to Wikipedia, it can produce a power output of 4 MW or 4,000 kW, when working on third-rail electrification.

This means, that in an hour, four thousand kWh will be transferred to the train using conventional third-rail electrification.

Or in a minute 66.7 kWh can be transferred.

In Vivarail’s system, because they are transferring energy between batteries, enormous currents can be passed.

To illustrate how batteries can can deliver enormous currents here’s a video of  a guy using two car batteries to weld things together.

These currents are possible because batteries have a low impedance and when the battery on the train is connected to the battery bank on the station, the two batteries will equalise their power.

If we take the example of the Class 92 locomotive and conventional electrification, this would be able to transfer 200 kWh in three minutes or 400 kWh in six minutes.

But I believe that battery-to-battery transfers could be at a much higher current

Thus in a typical one or two minute stop in a station, upwards of 200 kWh could be transferred to the train.

On this page of their web-site, Vivarail say this.

Due to the high currents required for the train Vivarail uses a carbon ceramic shoe able to withstand the heat generated in the process – without this shoe the charge time would make operational running unfeasible.

The devil is always in the details! From what I’ve seen and heard about the company, that would fit!

The Shape Of Solar Farms To Come

This article on Renew Energy is entitled Gannawarra Battery-Integrated Solar Farm – Australia’s Largest – Officially Opened.

These are the first two paragraphs.

The Gannawarra solar and energy storage project near Kerang in western Victoria has had its official launch on Friday, to mark the largest pairing of a solar farm and a grid-scale battery system in Australia.

State energy minister Lily D’Ambrosio officially anointed the landmark project, which has combined 60MW of PV panels and a 25MW/50MWh battery system – Tesla’s second-biggest battery in the country so far.

Form the video in the areticle, it appears that there are 120 hectares of solar panels and the farm provides enough electricity for 25,000 homes.

It is an interesting concept and I’m sure it will be repeated around the world.

Ausralia has lots of sun, but there is no reason, why a similar system can’t be developed with tidal, wave or wind power.

A Different Energy Storage Technology

Recently, two articles on the web have been caught in my Google alerts.

Both articles are about energy storage using a Vanadium Redox Flow Battery.

This is a paragraph from the Bushveld article.

The project will be implemented in two phases for a total of 1 400 MWh of energy storage capacity – 800 MWh in Phase 1 and an additional 600 MWh in Phase 2.

When you consider that with lithium-ion technology battery capacity is normally talked about in kWH, these are impressive amounts of stored energy.

Reading the Wikipedia post shows that the batteries rely on toxic chemicals like sulphuric acid and vanadium oxide, which would probably rule out mobile applications.

Conclusion

Having read all the two articles and the Wikipedia entry, I wouldn’t be surprised to see some form of technology like this emerge for large scale energy storage to back up intermittent power sources like solar, wind and wave.

UK Listed Energy Storage Fund Seeks 182MW Battery Project Pipeline

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

This is the first paragraph.

UK investment management firm Gresham House has confirmed it is to launch a fresh fund raising drive as it sets its sights on a new, 182MW pipeline of battery storage projects.

It is my belief as a Control Engineer, that if we move to renewable energy, like geothermal, hydro, solar, tidal, wave and wind, that the generating capacity must be backed up with large massive of energy storage.

  • The energy storage captures excess electricity when nobody needs to use it and feeds it back when consumption exceeds supply.
  • I suspect that the National Grid have done extensive simulations of the UK’s energy needs and that they have a model of how much energy storage is needed to support particular mixes and capacities of renewable energy.
  • Most of the storage will be lithium-ion or perhaps some of the newer developments, that are creeping into the renewable dictionary.
  • The cost of storage, its working life and performance must be well-known, which means that the investors can get a return, that satisfies their needs to fund pensions and insurance policies.

So it would appear that Gresham House have done their sums and come up with a mathematical model, where all are winners.

  • UK industry and consumers get enough electricity for their needs.
  • Insurance companies and pension funds get a return to fulfil their contractual commitments.
  • UK pensioners get a reliable pension.
  • UK taxpayers don’t have to fund the much-needed energy storage.
  • Our electricity will increasingly be generated by renewables.
  • I do suspect that Gresham House will take an appropriate fee.

There may even be an opportunity for the public to invest directly in the future.

For all these winners, there will be losers.

  • Oil companies. In Writing On The Wall For Oil Say Funds, I wrote about the opinion of fund managers on oil companies.
  • Despots, dictators and religious maniacs, who control much of the world’s oil resources.

I shall cry not one tear for the second group!

I’ll be very interested to see the way that these energy storage funds develop!

Conclusion

These funds will develop in parallel with renewable energy and the energy storage it needs.

As the demand for energy storage will grow significantly, these funds will grow as well to provide the capacity needed to keep the lights on.

Battery Storage Backers Energized By Prospect Of New Tax Credit

The title of this post is the same as that of this article on Bloomberg Tax

  • Thirty percent tax relief would be provided for energy storage.
  • It might also stand a chance of becoming law in the US.

Read the article and question as I did, that tax relief may be the best way to get investors to build energy storage to keep the lights on, when the wind’s not blowing and the sun’s not shining.

Whitehaven Deep Coal Mine Plan Moves Step Closer

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

This is the first three paragraphs.

The first new deep coal mine in the UK for decades has moved a step closer after councillors unanimously backed the plans.

The West Cumbria Mining Company wants to mine next to the site of the former colliery in Whitehaven that shut three decades ago.

The Woodhouse Colliery could create 500 jobs, but objectors have said mining will contribute to global warming.

I am not normally a friend or supporter of coal, but there might be a different agenda behind this mine.

The coal that will be mined at Woodchurch Mine, will not be burnt in a power station or steam engine, as it is being mined for a different purpose. It is high-quality metallurgical coal, Wikipedia says this about metallurgical coal.

Metallurgical coal is a grade of low-ash, low-sulfur and low-phosphorus coal that can be used to produce high grade coke. Coke is an essential fuel and reactant in the blast furnace process for primary steelmaking. The demand for metallurgical coal is highly coupled to the demand for steel. Primary steelmaking companies will often have a division that produces coal for coking, to ensure stable and low-cost supply

Currently, there is a shortage of this product and Europe import several million tonnes a year.

It also appears that the Cumbrian metallurgical coal is of a high quality and low in impurities.

In Wikipedia, there is an entry for the HIsarna ironmaking process.

This process is being developed by the Ultra-Low Carbon Dioxide Steelmaking (ULCOS) consortium, which includes Tata Steel and the Rio Tinto Group. Reduction in carbon-dioxide produced by the process compared to traditional steel-making are claimed to be as high as fifty percent.

This figure does not include carbon-capture to reduce the carbon-dioxide still further.

However, looking at descriptions of the process, I feel that applying carbon-capture to the HIsarna steelmaking process might be a lot easier, than with traditional steelmaking.

If you are producing high quality steel by a process like HIsarna, you want to make sure that you don’t add any impurities from the coal, so you have a premium product.

So is Cumbrian metallurgical coal important to the HIsarna process?

I obviously don’t know and it is not even certain that HIsarna will eventually become a mainstream way of producing high-quality steel.

But you can be assured that there are other companies trying to find the Holy Grail of producing high quality steel with low impurities and without creating masses of carbon-dioxide.

The company or organisation, who cracks this one will make a fortune ethically, as we’ll always need lots of high quality steel.

Conclusion

Mining coal in Cumbria may seem a retrograde step, but it could be central to cutting carbon-dioxide emissions in high-quality steel-making.

I’ll be watching this development with interest.

Government Turns Up Power On Offshore Wind

The title of this post, is the same as that of an article in yesterday’s copy of The Times.

This is the first paragraph.

A third of British electricity will be generated by offshore wind farms by 2030 under government plans.

Although Jeremy Corbyn said he would reopen coal mines a couple of years ago, I can’t see a change of Government stopping this.

A few other points from the article.

  • Last year offshore wind produced about eight percent of our electricity needs.
  • The offshore wind energy industry has said it will raise UK content from 48 to 60 percent.
  • The industry has promised to invest £250million in the supply chain.
  • There are 1,900 turbines in British waters, which can generate 8GW.
  • Another 6GW will come on stream by 2022-23.
  • Another 16GW are in the planning stage.

The author feels that as costs are reducing, this is driving the investment.

Conclusion

We have a very windy future.

Ovo Partners With Glen Dimplex To Deliver Smart Heating

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

If you read the article, you will find out how the humble electric storage heater could be joining the smart electricity grid.

This is a paragraph.

It says the facility to store excess energy can lower the cost of electrification by reducing the need for backup generation and investment in the power grid to increase its peak capacity. Analysis by Imperial College London has indicated that deploying smart flexible heating could cut decarbonisation costs by £3.9 billion per year.

This is going to be technology to watch.

Especially, if your heating needs are best met by some form of electric storage heaters.

Wind Farms Sale Is Breath Of Fresh Air After Merger Setback

The title of this post, is the same as that as an article in the Business pages of The Times.

This is the first paragraph.

Selling stakes in two wind farms for £635million will provide funds to reduce debt and to launch up to £200million of share buybacks, SSE said yesterday.

Amongst the purchasers of the stake in the wind farms is an unnamed British pension fund.

So yet again, we’re seeing pension funds investing our future in wind farms.

It is a trend that will continue, as pension funds look for safe places to put the massive funds they have under management.

  • We need the electricity the farms produce.
  • The engineering of wind farms will get better, and farms will be more reliable and produce electricity economically for years longer.
  • The farrms will probably get the best of maintenance, as pension funds will protect their investment.

In addition to wind, I suspect pension funds and insurance companies will invest in other large renewable energy schemes like solar and wave power and energy storage.

Schemes, such as those I mentioned in Exciting Renewable Energy Project for Spennymoor, will surely be ones that will appeal to the funds.

Conclusion

Pension funds and insurance companies with their massive funds are becoming a major force in vutting carbon emissions.

I suspect that this is not just a UK trend, but one with a world-wide dimension, that includes a lot of the EU, the Far East, North American and Australia.
