Air-Powered Energy Storage Knocks Out Coal & Gas — Wait, What?
The title of this post, is the same as that of this article on CleanTechnica.
After reading, this must read article, it could have had a title with Knocks Out Coal, Gas and Nuclear.
It makes a passionate article for Highview Power’s long term air-powered energy storage and other systems with a similar energy profile like Form Energy.
It also showed this good graphic from Highview Power, which shows how their system works.
This paragraph gives Highview’s view on what their CRYObatteries will do.
Grid operators are turning to long-duration energy storage to improve power generation economics, balance the grid, and increase reliability. At giga-scale, CRYOBatteries paired with renewables are equivalent in performance to – and could replace – thermal and nuclear baseload power in addition to supporting electricity transmission and distribution systems while providing additional security of supply,” enthuses Highview.
The author then chips in with the attitude of the US Department of Energy.
Don’t just take their word for it. The US Department of Energy is eyeballing long duration energy storage for the sparkling green grid of the future despite all the hot air blowing out of 1600 Pennsylvania Avenue.
In an interesting twist, the Energy Department’s interest in long duration storage was initially connected to its interest in at least preserving, if not growing, the nation’s aging fleet of nuclear power plants.
Will renewables be able to see off nuclear in a country with plenty of sun and/or wind like the United States?
Conclusion
With a lot of help from their friends in the long term energy storage business, the answer must be yes!
World First As Liquid-Air Energy Storage Makes Commercial Debut Near Manchester United Ground
The title of this post is the same as that of this article on Recharge.
I can add some extra information starting with this picture from Highview Power, which shows a visualisation of the CRYObattery.
Unfortunately, it doesn’t show any objects, which can give an idea of the size of the plant.
Levelised Cost Of Energy
LCOE or Levelised Cost Of Energy will be a term, that will be increasing used, when electricity generation is discussed. This is Wikipedia’s definition of the term.
The levelized cost of energy (LCOE), or levelized cost of electricity, is a measure of the average net present cost of electricity generation for a generating plant over its lifetime. The LCOE is calculated as the ratio between all the discounted costs over the lifetime of an electricity generating plant divided by a discounted sum of the actual energy amounts delivered. The LCOE is used to compare different methods of electricity generation on a consistent basis. The LCOE “represents the average revenue per unit of electricity generated that would be required to recover the costs of building and operating a generating plant during an assumed financial life and duty cycle.” Inputs to LCOE are chosen by the estimator. They can include cost of capital, “fuel costs, fixed and variable operations and maintenance costs, financing costs, and an assumed utilization rate.
Make sure, when comparing different LCOE values for different methods of energy generation, that the same method was used to calculate LCOE.
Comparative Costs
The article quotes the following costs on an LCOS or Levelised Cost Of Storage basis, which enables comparison to be made according to the same rules.
- A 200 MW/2 GWh CRYObattery will cost £110/MWh
- Pumped storage/hydro will cost £123-150/MWh
- Lithium-ion will cost £231-470/MWh
I have converted some from dollars.
I do think that a 2 GWh CRYObattery could be very good value!
Income
The article says this about how the CRYObattery will earn us keep.
Income will come through grid balancing, ancillary services such as frequency response and voltage support, and arbitrage — buying electricity when wholesale prices are low and selling it when prices are high.
I suspect that if a company like Carlton Highview Power had several large batteries around the country, this would be an advantage to the company.
15 More Fuel Cell Electric Buses For UK Roads
The title of this post, is the same as that of this article on H2 View.
This is the introductory paragraph.
A further 15 fuel cell electric buses (FCEBs) are planned for the UK this year, as the country works towards its goal of deploying 4,000 zero emission buses over the next five years.
These futher points are made.
The fuel cells are 85KW heavy-duty FCveloCity®-HD fuel cell modules from Ballard Power Systems.
This will take Wrightbus’s order book for hydrogen-powered buses to fifty. all of which will be delivered this year.
Twenty buses are for London and fifteen are for Aberdeen.
I have some thoughts on the 85KW heavy-duty FCveloCity®-HD Fuel Cell Module.
This pdf file on the Ballard web site is the data sheet and this is selected data.
- The net power is 85 kW
- The fuel cell weighs 256 Kg.
- It needs a coolant sub-system that weighs 44 Kg.
- It needs an air sub-system that weighs 61 Kg.
- It is a true zero-emission product.
It is worth looking at the power train of a New Routemaster bus, which although very different will probably give clues as to the weight that can be carried and the power and battery size needed for a full-size bus.
- The Cummins ISBe diesel engine develops 138 kW and weighs 499 Kg.
- The engine is mounted half-up the back stairs.
- The Microvast Lithium Titanate battery has a capacity of 18 kWh.
- The battery is placed under the front stairs.
- The braking on the New Routemaster bus is regenerative.
These are some of my observations.
- If you sit at the back of a New Routemaster bus, you can hear the engine, when it is running. On most routes in Central London, it certainly isn’t running all the time.
- The battery doesn’t seem very large at 18 kWh.
- The fuel cell with its sub-systems would appear to be lighter than the diesel engine, but of less power.
- The fuel-cell won’t need the generator of the diesel bus.
I very much feel getting all the components into a standard double-decker bus will be a tight squeeze, but none of the individual components are that large or heavy.
Conclusion
I can’t wait to have my first ride in a hydrogen-powered double-decker bus.
Will BALDIES Save The World?
I just had to use this new acronym, I’ve just found on the Internet.
BALDIES are Build-Anywhere-Long-Duration-Intermittent-Energy-Storage.
Atheists Less Likely To Die From Covid-19 Than Believers, Research Finds
The title of this post, is the same as that of this article in The Times.
This is the introductory paragraph.
People without religious faith are less likely to die from Covid-19 than believers, according to the first analysis of its kind from the Office for National Statistics (ONS).
This paragraph gives some actual statistics.
For Muslims the figures were 198.9 deaths per 100,000 males and 98.2 deaths per 100,000 females. Among Christians, the death rates were 92.6 for men and 54.6 for women, and among Jewish people 187.9 for men and 94.3 for women.
These are my observations.
The Average Death Rate
The average death rate of these religious groups is 121 per 100,000 people or 1 in 826 people.
The Number Of Coeliacs In The UK Population
This page on the NHS web site says this about the number of coeliacs in the UK population.
Coeliac disease is a condition that affects at least 1 in every 100 people in the UK.
But some experts think this may be underestimated because milder cases may go undiagnosed or be misdiagnosed as other digestive conditions, such as irritable bowel syndrome (IBS).
Reported cases of coeliac disease are around 3 times higher in women than men.
I hadn’t known the last point, but all my coeliac friends and acquaintances, with two exceptions are female! The two male exceptions are both chefs!
Thinking about the last point, I do wonder if women are more likely to have coeliac disease as the disease can affect their natural functions, so they are likely to go to the doctor with a problem, that could be a coeliac symptom, like the inability to conceive.
Diagnosed Coeliacs On A Gluten-Free Diet And Cancer
It has been shown by Joe West at Nottingham University, that diagnosed coeliacs on a gluten-free diet are less likely to get cancer, than the general population.
Does this mean, that this group of people have a strong immune system?
Diagnosed Coeliacs On A Gluten-Free Diet And COVID-19
Various doctors have said, that COVID-19 attacks people with compromised immune systems.
So do diagnosed coeliacs ona gluten-free diet get a measure of protection from COVID-19 from their strong immune systems?
Ashkenazi Jews And COVID-19
My coeliac disease comes from my great-great-great-grandfather, who was from Konigsberg in East Prussia.
In those far-off days at the start of the Nineteenth Century, if you were a Jewish male in East Prussia, you had to leave at eighteen, unless you were from one of the privileged Jewish families.
As my ancestor wasn’t a nenver of a privileged family, he hopped on a boat and ended up in Bexley.
Luckily, I was diagnosed as a coeliac at Addenbrooke’s hospital at the age of 50. My health, which had been poor off-and-on improved immediately and considerably, once I was no longer eating gluten.
But in the Jewish population, there are a lot of undiagnosed coeliacs, who probably have poor immune systems due to their diet.
Are they like targets in a shooting gallery for the evil COVID-19 virus?
Christians And COVID-19
I do wonder about communion rituals.
Especially, as some churches insist that wheat must be used. Even if you’re coeliac.
Surely, your health is more important.
Why Are Women Less Likely To Die Of Covid-19?
If undiagnosed coeliac disease is an explanation, as the disease is three times more common in women could explain it, if all coeliacs are on protective gluten-free diets.
Muslims And COVID-19
Most Muslims come from areas, where coeliac disease is rare and are probably on a gluten-free anyway.
But they do appear to suffer high levels of other diseases like diabetes, that compromise your immune system.
East Midlands Railway Class 170 Trains To Get New Emissions Technology
The title of this post, is the same as that of this article on Rail Advent.
These two paragraphs introduce the article.
Porterbrook has announced that it has received funding for the trial fitment of technology to reduce emissions on its fleet of Class 170 DMU trains.
The £400,000 funding will see the Class 170 ‘Turbostar’ trains, which are in operation with East Midlands Railway, fitted with Eminox SCRT technology.
The trial will be for three months, after which a decision will be made, as whether Porterbrook’s share of the over 120 Class 170 trains will be upgraded.
Two UK GDNs Considering New Fleet Of Zero-Emission Hydrogen Vehicles
This title of this post, is the same as that of this article on Hydrogen Fuel News.
This is the introductory paragraph.
Two UK gas distribution networks (GDNs) are investigating the potential of operating fleets of zero-emission hydrogen vehicles. The goal would be to use H2 fuel to shrink the carbon output from their fleet, aligning with the UK government’s Net Zero 2050 targets.
This surely is a good idea, as it says all the right things to their customers.
Climate Emission Killer: Construction Begins On World’s Biggest Liquid Air Battery
The title of this post, is the same at that of this article in the Guardian.
This is the introductory paragraph.
Construction is beginning on the world’s largest liquid air battery, which will store renewable electricity and reduce carbon emissions from fossil-fuel power plants.
These are a few points from the Guardian and other articles on other web sites, including Wikipedia.
- The size of the battery is 250 MWh.
- It can delivery up to 50 MW of power. which translates to five hours at full power, if the battery is full.
- If it was already working, it would be the ninth biggest battery of all types, except for pumped storage, in the world.
- It will be built at Trafford Energy Park near to Carrington power station.
- It will be double the size of the largest chemical battery, which was built by Tesla in South Australia.
- It is being built by a company call Carlton Highview Storage, which is a joint venture between Carlton Power and Highview Power.
- It should start commercial operation in 2022.
- The installation of the battery is an £85million project.
- The Government have chipped in with a £10million grant.
Some reports say, this could be one of four of Highview Power’s 250 MWh CRYObatteries to be developed by the joint venture.
I will add some observations of my own.
Carrington Power Station
This Google Map shows the site of Carrington Power station.
Note.
- Flixton station is in the North-East corner of the map.
- Irlam station is on the Western edge of the map.
- South of the railway between the two stations, there is a large industrial site, that sits in a bend in the River Mersey.
This second Google Map shows an enlargement of the site.
Note.
- Carrington power station in the middle of the site.
- Large amounts of brownfield land.
- The Manchester Ship Canal passing to the West of the site.
Wikipedia says this about the design of Carrington power station.
The station is a Combined-Cycle Power Plant (CCPP), using natural gas to generate 884MW of electricity. The CCPP uses both a gas and a steam turbine together, to produce up to 50 percent more electricity from the same fuel than a traditional simple-cycle plant. The waste heat from the gas turbine is routed to the nearby steam turbine, which generates additional power. Carrington consists of two CCPP KA26-1 units. At operating design conditions, each CCPP unit generates 442.3 MW net output. The station generates enough power to meet the electricity needs of one million homes in the UK and began commercial operation on 18 September 2016.
Wikipedia also says the following.
- The plant has an efficiency of 58%. Is that good for this type of gas-fired Combined Cycle Gas Turbine power station? 64% seems to be about the best but Carrington is better than the about 50% possible with a conventional gas turbine plant.
- Much of the heavy equipment for the power station was brought by barge along the Manchester Ship Canal.
- The station is also a combined heat and power plant, capable of providing nearby businesses with steam, if they require a supply. This could be useful to a Highview Power CRYObattery, as a low-grade heat-source is needed to recovery the stored energy by warming the liquid air.
Given the following.
- There is space available near to the power station.
- A 250 MWh CRYObattery would probably fit in a size smaller than two football pitches.
- Carlton have permission to build another CCGT at the site.
- Carrington has a very good electrical connection to the grid, as nearly all power stations do.
- Heavy components can be brought in by barge on the canal.
, it would appear that the area would be a good place to site the first gr-scale CRYObattery.
Conclusion
I think siting the first grid-scale CRYObattery close to Carrington power station at the Trafford Energy Park, fits together well and I could see more CRYObatteries being installed in the following types of location.
- At existing power stations.
- On the sites of demolished power stations, that still have good grid connections.
- Where interconnectors and power from offshore wind connects to the grid.
I wouldn’t be surprised to see Drax Group install a system at one of their sites, as a CRYObattery could help cut their carbon-emissions.
Who Needs Offices? Zopa Doesn’t!
opa’s update to all their investors yesterday.
It had a sub-heading of At Zopa!
Finally, a quick update on where we’re at as a company. All of our staff are still working remotely. Our diligent preplanning for a situation in which we could lose access to our offices has meant we’ve been able to continue to serve our customers throughout the pandemic, while also implementing new solutions to adapt to this unprecedented situation. Like other businesses, we’ve been planning for what a return to our offices looks like. But as we’ve been able to keep serving your needs while operating from home, we are in no rush. Being in this position allows us to stay focused on supporting your needs during this challenging moment.
How many companies after we are through the COVID-19 pandemic will decide to downsize their office requirements considerably?
The World’s First Bi-Mode Hydrogen-Electric Train
This news page on the University of Birmingham web site is entitled HydroFLEX Secures Funding For Hydrogen-Powered Train Design.
The page is mainly about the new funding from Innovate UK, that I wrote about in First Of A Kind Funding Awarded For 25 Rail Innovation Projects, but it also includes this significant paragraph.
As well as being the UK’s first hydrogen-powered train, HydroFLEX is also the world’s first bi-mode electric hydrogen train. It will be undergoing mainline testing on the UK railway in the next few weeks.
One of my disappointments in the design of the Alstom Coradia iLint, is that, it is designed as a hydrogen-power only train, where it could surely have had a pantograph fitted, for more efficient working.
Consider.
- I suspect many hydrogen-powered trains will only be doing short distances, where electrification is not available, so daily distances under hydrogen power could be quite short.
- In the UK, a smaller hydrogen tank would certainly ease the design problems caused by a large fuel tank.
- There have been improvements in hydrogen storage in recent years.
The funding award to the project talks about raft production, so are the engineers, aiming to design a hydrogen power-pack on rafts, that could be fitted underneath the large fleets of retired electric multiple units, that are owned by Porterbrook.
Now that would be a game changer.
- Porterbrook have thirty-seven Class 350 trains, that will be replaced in the next few years by new trains. The electric trains are less than a dozen years old and Porterbrook have been talking about fitting batteries to these trains and creating a battery/FLEX train. Would making these trains bi-mode hydrogen-electric trains be better?
- Birmingham wants to open up new rail routes in the city on lines without electrification. What would be better than a hydrogen powered train, designed in the city’s premier university?
- Routes from Birmingham to Burton-on-Trent, Hereford, Leicester, Shrewsbury, Stratford-on-Avon and Worcester would be prime candidates for the deployment of a fleet of bi-mode hydrogen-electric trains.
- Birmingham have already asked ITM Power to build a hydrogen filling station in the city for hydrogen buses.
