Plans To Turn Czech Coal Mine Into Storage, Hydrogen And Solar Hub
The title of this post, is the same as that of this article on Power Engineering International.
This is the sub-heading.
Mine is also going to be the site of an experimental greenhouse project called Eden Silesia
This paragraph outlines Eden Silesia.
The site will also be home to an experimental greenhouse project called EDEN Silesia, managed by the Silesian University of Technology and based on the concept of the Eden Project in Cornwall, England.
It does seem that the Czechs are creating a comprehensive facility around a Gravitricity energy store.
This Gravitricity system is only a 4MW/2 MWh system, but there is also this quote from the company.
Future multi-weight systems could have a capacity of 25MWh or more.
If the concept works, this could be imitated in several countries around the world?
Have We Missed The Boat On Fracking?
I have just re-read my post from October 2019, which was entitled Fracking Hell…Is It The End?, where these were my conclusions.
- Fracking for hydrocarbons is a technique that could be past its sell-by date.
- The use of natural gas will decline.
- INEOS could see hydrogen as a way of reducing their carbon footprint.
- The heating on all new buildings should be zero carbon, which could include using hydrogen from a zero-carbon source.
- There are reasons to think, that electricity from wind-farms creating hydrogen by electrolysis could replace some of our natural gas usage.
So will the Government’s lifting on the ban on fracking make any difference?
The announcement is detailed in this article on the BBC, which is entitled Fracking Ban Lifted, Government Announces.
These are my thoughts.
Fracking Is Not A Quick Fix
My personal view is that to achieve any significant amounts of gas from fracking will take some years, so it is not something that will be available in the short term.
Opposition To Fracking Won’t Help
There are very few inhabitants of the UK, who are enthusiastic about fracking.
Opposition to fracking will make it less likely to be the feasible short term fix we need in the UK.
Suppose There Was An Earthquake Near To A Fracking Site
Fracking also has the problem, that if there were to be a small earthquake near to a site, even if it was very likely to have not been caused by fracking, it would result in massive public uproar, which would shut down all fracking in the UK.
This to me is a big risk!
Would The Jackdaw Oil And Gas Field Be A Medium Term Solution?
- In Shell’s Jackdaw Gas Field Given Go-Ahead By Regulators, I wrote about Shell’s Jackdaw field, which has been given the go-ahead.
- It could be able to provide 6 % of North Sea gas production.
- It should be fully operational by 2025.
I believe that with other gas field developments and imports, Jackdaw could keep us supplied with enough gas until the end of the decade.
Future Renewable Electricity Production
In Will We Run Out Of Power This Winter?, I summarised the likely yearly additions to our offshore wind power capacity in the next few years.
- 2022 – 3200 MW
- 2023 – 1500 MW
- 3024 – 2400 MW
- 2025 – 6576 MW
- 2026 – 1705 MW
- 2027 – 7061 GW
Note.
- Ignoring 2022 as it’s going, this totals to 19.2 GW.
- Hopefully, by the end of 2027, Hinckley Point C will add another 3.26 GW
- According to Wikipedia, there are currently 32 active gas fired combined cycle power plants operating in the United Kingdom, which have a total generating capacity of 28.0 GW.
I think it is not unreasonable to assume that some of the electricity will enable some of our gas-fired power stations to be stood down and/or mothballed.
Gas consumption would be reduced and some power stations would be held in reserve for when the wind was on strike!
Using Hydrogen To Eke Out Our Gas
Consider.
- In Lime Kiln Fuelled By Hydrogen Shown To Be Viable, I wrote about how hydrogen can be used instead of or with natural gas to fuel a lime kiln.
- There are other processes, where hydrogen can be used instead of or with natural gas.
- Using more hydrogen will reduce the amount of carbon dioxide emitted.
Perhaps we should strategically build a few huge hydrogen electrolysers, so that some large industrial users can cut back on their natural gas.
Will Energy Storage Help?
Energy storage’s main use is to mop up all the surplus electricity when demand is low at a low price and sell it back, when demand is high.
If we waste less energy, we will use less gas.
Will District Heating Schemes Help?
Consider.
- In Eden Project: Geothermal Heat Project ‘Promising’, I wrote about the Eden Project’s plan to extract heat from a borehole.
- In ‘World-First’ As Bunhill 2 Launches Using Tube Heat To Warm 1,350 Homes, I wrote about a district heating scheme in Islington, that uses heat from the London Underground.
- In Exciting Renewable Energy Project for Spennymoor, I wrote about a district heating scheme, that uses heat from abandoned coal mines.
More schemes like this should be developed, where there is a readily-available source of heat or electricity
Conclusion
As we add more renewables to our energy generation, it appears to me, that our gas usage will decline.
If we were to go fracking, we should have done it a lot earlier, so we can bridge the short term gap.
Eden Project: Geothermal Heat Project ‘Promising’
The title of this post, is the same as that of this article on the BBC.
This is the first paragraph.
A three mile-deep (4.8km) borehole has shown “promising” prospects for a geothermal heat plant in Cornwall.
Eden estimates the borehole can produce enough heat for 35,000 homes.
Geothermal energy is only at the beginning in the UK, but just because we don’t have any active volcanoes, we shouldn’t discount it.
On the other hand, we do have a lot of water-filled abandoned coal mines, which in former mining areas of the UK can and will provide a substantial amount of district heating, as I wrote in Exciting Renewable Energy Project for Spennymoor.
And then there’s one-off project’s like Bunhill 2 in Islington, which I wrote about in ‘World-First’ As Bunhill 2 Launches Using Tube Heat To Warm 1,350 Homes.
Conclusion
The UK may not be an Iceland, Indonesia, Italy, New Zealand, Philippines or the USA, but according to Wikipedia we have a good potential.
- Deep geothermal resources could provide 9.5GW of baseload renewable electricity.
- Deep geothermal resources could provide over 100GW of heat.
I think my most significant post on geothermal energy is Schlumberger New Energy And Thermal Energy Partners Form Geothermal Development Company STEP Energy.
Schlumberger and the other oilfield services companies have a very serious problem.
With countries abandoning oil and gas, they have lots of engineers, geologists and other staff, who will not be needed by the oil and gas industry.
But their expertise and skills can be transferred to the geothermal heat and power industry. This will benefit the staff, the companies and the world!
The other place there expertise can be used is in the storage of captured carbon dioxide.
