The Anonymous Widower

There’s A Hole In The Bus

If you’re musical, you can sing it to the tune of the famous Harry Belafonte song.

If you not, then give us a rest, or take singing lessons.

I took this picture of the seat in front of me on the new BYD battery-electric bus this morning.

 

Has the stop button been nicked or has it just fallen out?

Or it could be the centuries old problem of finding good, reliable slaves?

A Nightmare Coming Home

I nearly always come home via Moorgate station, as it has good train and bus connections and I can get both the 141 and 76 buses to near my house.

  • The 76 bus is my preference as it is a reliable New Routemaster.
  • But the 141 bus takes me all the way home. Unfortunately, it is generally a Chinese BYD battery-electric bus.

Coming home, I arrived at the Northchurch Road in a 76 bus.

  • The time was 11:29 and a text said that 141 buses were due in 1, 8, 19 and 20 minutes.
  • A second text at 11:39 said that buses were due at 4 and 12 minutes.

Eventually, I got on a 141 bus at 11:44.

This is typical, as the buses don’t seem to synchronise with Transport for London’s bus reporting system.

But today in the cold weather, they have been particularly unreliable.

So I asked Google AI, if hydrogen buses are more reliable in the cold and received this answer.

Yes, studies show hydrogen fuel cell buses generally outperform battery-electric buses (BEBs) in cold weather, experiencing less range reduction because their fuel cells generate waste heat that helps warm the cabin, while BEBs must draw significant energy from the battery for heating, drastically cutting range. While BEB range can drop significantly (over 30%), hydrogen buses see a smaller dip (around 23%), making them more reliable for cold climates.

Sixty years ago, I was using nickel-cadmium batteries to make portable instruments in a chemical factory and I think that they hated the cold, but that lithium-ion solved the problem. Obviously, it doesn’t!

But I do have my suspicions about the design and build quality of these BYD buses!

E.ON, Superdielectrics Develop Polymer-Based Battery Tech For Residential Storage Applications

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

These two introductory paragraphs outline the deal.

Energy supplier E.ON and energy storage technology firm Superdielectrics have joined forces to promote and develop a new battery technology for stationary storage applications.

The new BESS technology takes a unique approach by using a polymer-based technology, with the main component being a membrane similar to contact lens materials. According to the two companies, these polymer batteries are both more affordable and more environmentally friendly than their lithium-ion counterparts.

I believe that this battery could be a game-changer. Especially, for those like me, who have solar panels on their roofs.

Check out the Superdielectrics web site for more details.

I First Spotted Superdielectrics In 2019

I wrote about them in Is Cambridge Going To Save The World From Global Warming? in 2019.

This was my conclusion in that post.

I have been observing technology since the 1960s.

This is either one of those scientific curiosities , like cold fusion, that appear from time-to-time and then disappear into the scientific archives or become a game-changer.

I suspect we’ll know in a couple of years.

But even if it is isn’t the solution to affordable and massive energy storage,, that will save the world, I believe that one of the teams of men and women in white coats, somewhere in the world will crack the problem.

It looks like they’ve taken longer than I thought they would.

Note though, that in the linked post, they have a link-up with Rolls-Royce.

Conclusion

This is one of the great energy breakthroughs of my life-time.

DOE Funds Research Into Long-Duration Energy Storage Using Lead-Acid Batteries

The title of this post, is the same as that of this article on Best Magazine.

This is the sub-heading

US federal cash is on its way to fund research into long-duration energy storage using lead-acid batteries.

These two paragraphs give more details.

A consortium backed by industry bodies Battery Council International and the Consortium for Battery Innovation, will conduct pre-competitive research aimed at improving lead battery performance. Companies participating in the consortium include Advanced Battery Concepts, C&D/Trojan, Clarios, Crown Battery, East Penn Manufacturing, EnerSys, Gridtential and Stryten Energy. The collaborating national laboratories are Argonne, Oak Ridge and Pacific Northwest (PNNL).

The $5 million award from the US Department of Energy, announced on 27 September, will support work to develop lead batteries capable of 10+ hours of storage with a pathway to $0.05/kWh levelised cost of storage by 2030.

Note.

  1. The companies involved have names that indicate they could be battery makers.
  2. The collaborating national laboratories are world-class Premier League players.
  3. Over the nearly fifty years, that I drove cars, lead-acid batteries improved a lot and there might be more to come.
  4. The last paragraph is ambitious, unless they know more than I do about lead-acid batteries. Which is likely!

This is also said in one of Highview Power’s news items.

Highview Power, the global leader in long-duration energy storage solutions, is pleased to announce that it has developed a modular cryogenic energy storage system, the CRYOBattery, that is scalable up to multiple gigawatts of energy storage and can be located anywhere. This technology reaches a new benchmark for a levelized cost of storage (LCOS) of $140/MWh for a 10-hour, 200 MW/2 GWh system. Highview Power’s cryogenic energy storage system is equivalent in performance to, and could potentially replace, a fossil fuel power station. Highview Power’s systems can enable renewable energy baseload power at large scale, while also supporting electricity and distribution systems and providing energy security.

The battery researchers are saying $0.05/kWh levelised cost of storage by 2030 and Highview Power are saying $0.14/kWh for the same parameter.

Could Elon Musk’s Relationship With Donald Trump Be The Fly In The Ointment?

Would Musk want research to go on, that might weaken the use of his lithium-ion batteries for stationary applications?

Would You Buy A Battery Energy Storage System From Rolls-Royce?

I don’t often click on adverts that appear in web pages.

But I had to click on one from Rolls-Royce mtu, which advertised Battery Energy Storage Systems.

I wonder what the Honourable Charles Rolls would have thought of adverts on the Internet for the company he jointly founded?

I suspect he would have liked the idea, as Rolls was very much a promoter of motoring and aviation and opened one of the first car dealerships in the UK, according to his Wikipedia entry.

The Wikipedia entry for his business partner; Sir Henry Royce starts with this sentence.

Sir Frederick Henry Royce, 1st Baronet, OBE (27 March 1863 – 22 April 1933) was an English engineer famous for his designs of car and aeroplane engines with a reputation for reliability and longevity.

He is also described as a perfectionist.

This sentence from the Wikipedia entry, describes how he started the design of the legendary “R” engine.

In October 1928, he began design of the “R” engine while walking with some of his leading engineers on the beach at West Wittering, sketching ideas in the sand. Less than a year later, the “R” engine, designed in his studio in the village, set a new world air speed record of 357.7 miles per hour and won the Schneider Trophy of 1929.

Later with help from the maddest person my father ever met (his words, not mine!) ; Lady Houston, the Supermarine S.6B won the trophy in 1931 and then broke the world speed record at over 400 mph. Not bad for a seaplane. Take the floats off an S.6B and you almost have a Spitfire.

The Wikipedia entry also describes how the “R” engine was developed into what many engineers believe was the finest internal combustion engine of all time; the Rolls-Royce Merlin.

Following the success of the “R” engine, it was clear that they had an engine that would be of use to the Royal Air Force. As no Government assistance was forthcoming at first, in the national interest they went ahead with development of what was called the “PV-12” engine (standing for Private Venture, 12-cylinder). The idea was to produce an engine of about the same performance as the “R”, albeit with a much longer life. Rolls-Royce launched the PV-12 in October 1933 and the engine completed its first test in 1934, the year after Royce died. The PV-12 became the Rolls-Royce Merlin engine.

Where would we have been in the Battle of Britain without the Merlin engine?

Since 1969, the engineers at Rolls-Royce have followed Sir Henry’s example of perfection and developed the revolutionary RB-211 into the modern day Trent, which is now about to take a big leap into a low-carbon future with the UltraFan.

If the quality of Rolls-Royce mtu’s Battery Energy Storage System matches the levels of perfection Rolls-Royce achieved with the Merlin and the Trent, then I suspect that Sir Henry would have given his approval.

This picture is shown on the web page for the Battery Energy Storage System.

These two paragraphs introduce, what Rolls-Royce mtu are calling the mtuEnergyPack.

In today’s world of economic growth and increasing populations, the demand for electricity is soaring. Governments and industries globally shift to distributed renewable energy, challenging centralized grids. To adapt to this changing energy landscape, the mtuEnergyPack offers an ideal solution.

It integrates renewable sources like solar and wind power, paving the way for future-ready sustainable power systems. The mtu EnergyPack is a scalable, all-in-one solution for autonomous off-grid facilities. It ensures reliable power through peak shaving, load-shifting, and grid stabilization, making it suitable for various applications.

These are my thoughts.

What Is The Output And The Storage Capacity?

This paragraph on this page gives this answer.

It efficiently stores electricity from distributed sources and delivers on demand. The mtu EnergyPack is available in different sizes: The QS and the QL, ranging from 200 kVA to 2,000 kVA, and from 312 kWh to 2,084 kWh, and the QG for grid scale storage needs, ranging from 4,400 kVA and 4,470 kWh to virtually any size.

It seems that you specify your requirements and Rolls-Royce mtu should be able to satisfy it.

What Devices Can Be Connected?

This paragraph on this page gives this answer.

The mtu EnergyPack serves as a key component in enhancing the reliability and profitability of microgrids and energy systems. It stores electricity generated by distributed power sources, including gensets, wind turbines, or solar panels, and delivers it when needed.

In the 1970s, when I was working at ICI, others in the section were working on a system called MEDIA, where every sensor on a chemical plant was connected to the central computer, through its own analog-to-digital computer. It would now be called plug-and-play by some.

I believe that Rolls-Royce mtu are using similar ideas to connect equipment to the control computer.

These are my thoughts about connecting various equipment.

I don’t see why every device can’t work to the same protocol.

What Is The Power Density Like?

This paragraph on this page gives this answer.

The mtu EnergyPack’s compact battery system designs suit projects with limited space and logistical restrictions.

In ‘Spirit of Innovation’ Stakes Claim To Be The World’s Fastest All-Electric Vehicle, I talked about Rolls-Royce’s record-breaking electric plane called Spirit of Innovation.

Has what has been learned about energy storage in the confined spaces of an aeroplane been applied to a Battery Energy Storage System?

What Do Rolls-Royce mtu Consider To Be Important Features?

On this page, they list these features.

  • Power Density
  • Digitally Connected
  • Multilevel Safety
  • Black Start Capability
  • Scalability
  • Ultra-Fast Response
  • Flexible Use
  • Plug-And-Play Installation

The design seems to have everything covered.

Can Similar Systems Be Designed By Others?

I would expect that similar systems can be designed, as technology like batteries is available to all and the operation is only as good as the software controlling the various components of the system.

But similar systems will be without the famous Rolls-Royce logo.

Could One Of These Systems Decarbonise A Village?

I once lived in a village with about fifty houses and perhaps a hundred inhabitants.

I suspect an mtuEnergyPack could control all these inputs and provide the village with the following.

  • Enough electricity to power all the needs of the inhabitants, businesses and their vehicles.
  • If an electrolyser were to be provided, it could probably produce enough hydrogen to power every boiler and hydrogen-powered vehicle.

Note.

  1. Farmers would like the local availability of hydrogen, as it will be ideal for tractors and agricultural machinery.
  2. I actually believe that if a village had a reliable and affordable hydrogen supply, that a large proportion of the inhabitants would switch to hydrogen-powered vehicles.

There would still be the National Grid there for backup.

Conclusion

If I needed an mtuEnergyPack, I’d certainly give one a close look.

BAE To Produce Batteries For Electric Passenger Plane

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

This is the first paragraph.

BAE Systems is stepping back into the world of passenger aircraft manufacturing by partnering with a Swedish electric planemaker.

I must admit, that I’m not surprised about BAE Systems’s decision.

Aviation needs batteries for many purposes including drones, starting aircraft and auxiliary power sources, so I wouldn’t be surprised that BAE Systems know their batteries.

In The Big Beast In Your Electric Bus, I described the company’s involvement in providing batteries for electric buses in the United States.

As a former private pilot, I’m watching electric aviation with interest.

I am also an applied mathematician and control engineer and feel that electric aviation will always be playing catch up against planes powered by hydrogen and sustainable aviation fuel.

Look at some of Airbus’s ZeroE designs, which use hydrogen fuel.

Discover the three zero-emission concept aircraft known as ZEROe in this infographic. These turbofan, turboprop, and blended-wing-body configurations are all hydrogen hybrid aircraft.

Although saying that there are large numbers of orders for electric airliners like this Swedish design and the Eviation Alice.
