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 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?

If undiagnosed coeliac disease is an explanation, as the disease is three times more common in women would explain it, as they’d all be 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.
