Hydrogen Tourist Transport Network Trialled In The Peak District
The title of this post, is the same as that of this article on Fleet News.
This paragraph outlines the trial.
A trial is taking place in the Peak District National Park where hydrogen fuel cell electric vehicles (FCEVs) and electric vehicles (EVs) will run together between multiple destinations and attractions.
Note.
- Toyota will provide the buses.
- Air Products is providing hydrogen.
- The services appear to be centred on Chesterfield station.
It looks like one of the objectives is to test the two types of buses against the terrain.
I can see hydrogen-powered buses being used extensively in tourist areas all over the world.
The New Generation Of Pumped Storage Systems
This excellent article on GreenTechMedia is entitled The 5 Most Promising Long-Duration Storage Technologies Left Standing.
One of the technologies the article discusses is pumped storage, which in the UK is used at the massive Electric Mountain in Snowdonia, which can hold 9.1 GWh of electricity and supply up to 1,800 MW of electricity when needed. That’s not bad for 1970s engineering!
The GreenTechMedia article introduces pumped storage like this.
Midcentury modern design is hot again, so why not midcentury storage technology? This gravity-based concept physically moves water from a low to a high reservoir, from which the water descends, when needed, to generate electricity. This dates from way before lithium-ion’s heyday and still provides some 95 percent of U.S. grid storage, according to the U.S. Department of Energy.
The largest pumped storage system in the US is Bath County Pumped Storage Station, which is described as the biggest battery in the world. With a storage capacity of 24 GWh of electricity and a generating capacity of 3,003 MW, it dwarfs Electric Mountain. But then the Americans have bigger mountains.
Pumped storage is a good partner for intermittent renewables like wind and solar, but in a country like the UK, the US and other countries with strong planning laws getting permission to build a large pumped storage system is not easy. We tried to build one on Exmoor, but that was abandoned.
Note that the country building the most new pumped storage systems is China, where they have mountains and planning laws, that would not be acceptable anywhere else.
But engineers have come up with a new design, described in this paragraph from the GreenTechMedia article.
The new school of pumped hydro focuses on isolated reservoirs that don’t disrupt river ecosystems; this simplifies permitting, but projects still face a decade-long development timeline and billion-dollar price tags.
It then gives two examples of proposed systems.
Gordon Butte Pumped Storage Project
The operation of the Gordon Butte Pumped Storage Project is described like this in Wikipedia.
Gordon Butte will be located on a 177 acres (0.72 km2) site, and will have access to water from Cottonwood Creek, a tributary of the Musselshell River. The facility will operate as a closed system, without actively drawing or discharging water into the watershed. It will have a 4,000 acre-foot capacity reservoir, located 1,000 feet (300 m) above the base, with a power generation capacity of about 400 MW
The smaller size must make it easier to get it built.
How much energy will Gordon Butte hold in GWh?
- A 4,000 acre-foot reservoir has a capacity of 4,933,927.42128 cubic metres.
- As a cubic metre of water weighs a tonne, the reservoir can hold 4,933,927.42128 tonnes of water at an altitude of 300 metres.
- Using Omni’s Potential Energy Calculator, this gives a potential energy of 4,032,108 KWh.
This is just over 4 GWh.
Ths facility could supply 400 MW for ten hours or 4 MW for a thousand hours!
It should be noted that Electric Mountain has an efficiency of 74-76%.
Eagle Mountain Pumped Storage Facility
Eagle Mountain Pumped Storage Facility is introduced like this on its web site.
The pumped storage hydropower project at Eagle Mountain, CA will transform a scarred brownfield site into a 1,300 Megawatt generator of green electricity that can light one million homes. The site is in a remote part of the Mojave Desert, more than 50 miles from the nearest city, Blythe, CA, and more than 60 miles from Palm Springs and the Coachella Valley. The construction of the project will create thousands of jobs and add millions of dollars to the local economy while adhering to the most rigorous environmental standards.
Note that it is turning an eyesore of the worst kind into a pumped storage facility. It’s surely better than using it for landfill!
Conclusion
Systems like these may have applications in the UK!
Could some of those massive quarries in the Peak District be converted into pumped storage systems, using the technology of my two examples?
This Google Map shows the quarries surrounding the town of Buxton.
Note.
- The white areas looking almost like clouds are quarries.
- Buxton has an altitude of three hundred metres, which is the altitude of the Gordon Butte Storage Project.
- The vast Tunstead Quarry, which is four kilometres East of Buxton has an area of over one square mile.
- Tunstead Quarry has a red arrow above it marked Buxton Lime and Cement.
Could we not extract as much limestone as is possible from Tunstead and then convert it into a pumped storage system like Gordon Butte? It could have an area of 2.5 square kilometres and an altitude of nearly a thousand feet. A rough estimate, based on Gordon Butte, indicates it could store over 10 GWh.
Hopefully, better hydro-electric power engineers than myself, are looking at the quarries in the Peak District, with eyes flashing like cash registers.
There is one pumped storage project under development in the UK at the present time; Snowdonia Pumped Hydro, which obtained planning permission in 2017.
These are some characteristics.
- Situated in Snowdonia in old slate quarries at Glyn Rhonwy.
- 99.9 MW of power
- 700 MWh of storage capacity.
- 2 reversible turbines
- Start to full power in 12 seconds
- Cycle efficiency of around 81%
- Project lifespan of 125 years
- Estimated carbon saving of 50,000 tonnes per year
It is under a tenth the size to Electric Mountain, but every little helps.
I would also feel that with a 125 year life, it could be the sort of investment, that would appeal to a Pension Fund.
Derby To Manchester The Midland Way
I was trying to find out about two stations; Miler’s Dale and Monsal Dale, which are both on the Manchester, Buxton, Matlock and Midland Junction Railway.
I found this article in the Derby Telegraph, which is entitled 50 years on, as passengers return to railways, in a few quiet corners, Beeching’s cuts are being reversed.
It says a lot about the Midland’s spectacular route from Derby to Manchester.
As a result, some of the lines and stations axed in the Beeching Report are being brought back to life. One of these is the Midland Railway, a route which once linked Derby and Manchester.
It is regarded as one of the most spectacular lines ever built. Cutting through the Peak District, numerous tunnels and other impressive civil engineering features, including magnificent viaducts at Millers Dale and Monsal Dale, had to be constructed because of the terrain.
In 1967, the Beeching Report brought about the end of passenger services on the line with the closure of stations at Millers Dale, Bakewell, Rowsley, Darley Dale and Matlock Bath. Now a three-and-a-half-mile section of the line has since been reopened and brought back into use by Peak Rail.
Today, the company operates both a steam and heritage diesel service for tourists and visitors to both the Peak District and the Derbyshire Dales. The preserved railway line operates trains from Matlock station via Matlock Riverside and Darley Dale to Rowsley South.
Peak Rail has ambitions to reopen more of the line in the future. The first stage would be to relay track to the site of Rowsley station, extending to a total of 4.25 miles. There are also plans to extend the line all the way to Bakewell, which would involve the restoration of both the Haddon tunnel and Coombs Road viaduct as well as the reinstatement of numerous bridges along the way.
It certainly seems to be worth a visit.
It sounds to me though to get trains running all the way will need a friendly billionaire.
