Hydrogen Islands
I found this concept on the ITM Power web site.
This was the sub-title.
Islands tend to have abundant renewable resources yet they rely heavily upon importing fossil fuels, often at relatively high cost.
And this was the body of the page.
The integration of renewables into an island’s power grid soon creates substantial balancing and curtailment problems. These can be overcome by deploying controllable rapid response electrolysers to produce green hydrogen for the island’s transport, heat and power sectors. Projects such as BigHit are demonstrating how this may be achieved.
It would create a zero-carbon island for an Internet tycoon or a Bond villain.
I’m certain that the concept would work for somewhere like a farm or even a small village, which is effectively a landlocked island, with perhaps wind turbines or solar panels.
ITM Power and Ørsted: Wind Turbine Electrolyser Integration
The title of this post is the same as that of this press release from ITM Power.
This is the introductory paragraph.
ITM Power (AIM: ITM), the energy storage and clean fuel company, is pleased to share details of a short project sponsored by the Department for Business, Energy & Industrial Strategy (BEIS), in late 2019, entitled ‘Hydrogen supply competition’, ITM Power and Ørsted proposed the following: an electrolyser placed at the wind turbine e.g. in the tower or very near it, directly electrically connected to the DC link in the wind turbine, with appropriate power flow control and water supplied to it. This may represent a better design concept for bulk hydrogen production as opposed to, for instance, remotely located electrolysers at a terminal or platform, away from the wind turbine generator, due to reduced costs and energy losses.
Some points from the remainder of the press release.
- Costs can be saved as hydrogen pipes are more affordable than underwater power cables.
- The proposed design reduces the need for AC rectification.
After reading the press release, it sounds like the two companies are performing a serious re-think on how wind turbines and their links to get energy on-shore are designed.
Will they be using redundant gas pipes to bring the hydrogen ashore?
I think, that they could go further than that!
- Imagine a very large wind farm built over a cluster of redundant gas-fields that are suitable for the storage of gas.
- The wind farm will produce hydrogen, which could be either sent to an onshore terminal or stored in one of the redundant fields.
- When hydrogen is needed onshore, it can come from the turbine/electrolysers in the wind-farm or from offshore storage.
- The pipeline to the shore would probably also be reversible and used to take carbon dioxide offshore for storage.
- If more electricity is needed onshore, the hydrogen is used as fuel for a gas-fired power station.
It sounds complicated, but hydrogen gives a lot of flexibility, as it is easily converted to and from electricity.
Controlling this network is a classic problem for Control Engineers and sophisticated computers will make sure, there is both enough electricity and gas.
The other application for combined wind turbines and electrolysers is where there is a need for moderate amounts of gas in the middle of nowhere.
Uses could include.
- Large farms all over places like East Anglia, much of North America, Australia and Serbia, where it would be used for motive power and heating.
- Islands like the Orkneys to decarbonise heating and transport and especially aviation and small ships like tugs and ferries.
- Hydrogen filling stations for trucks and other vehicles in places like the Mid West and large parts of Africa and Asia.
- Large transport depots, that switch from diesel to hydrogen might install their own combined wind turbine and electrolyser.
- Ports of all sizes will switch to hydrogen and smaller ports may well use combined wind turbines and electrolysers.
- Will isolated villages and small towns have their own combined wind turbines and electrolyser to bring a much needed gas supply?
I used to own a farm and I would certainly have looked at the technology to see, if it was worth installing.
It is my view, that combined wind turbines and electrolysers are one of those enabling technologies, that will find lots of different applications.
HyDeploy
I could have called this post; What Do You Do With Surplus Electricity?.
Believe it or not, one thing you can do is inject it into the gas main, by converting it into hydrogen first.
The Project
The concept is being tested in a project called HyDeploy at Keele University.
- The project has its own web site, from where I have obtained much of the information on this post.
- Keele University has its own gas network.
- Keele has a campus population similar to a small town.
- Keele University has a reputation for research excellence.
This paragraph outlines the project.
HyDeploy is a pioneering energy demonstration to establish the potential for blending hydrogen, up to 20%, into the normal gas supply so that we can reduce carbon dioxide (CO2) emissions.
A 10 month live demonstration of blended gas is taking place on part of the Keele gas network and will finish in August 2020.
HyDeploy will help to determine the level of hydrogen which can be used by customers safely and with no changes to their existing domestic appliances.
The HyDeploy project has been split into the following phases.
- Phase One will be live test using the Keele University gas network to learn about injecting hydrogen into a natural gas network.
- Phase Two will move to a larger demonstration on public network in the North East.
- Phase Three will be another large demonstration in the North West.
Once the evidence has been submitted to Government policy makers, we very much expect hydrogen to take its place alongside other forms of zero carbon energy in meeting the needs of the UK population.
The Electrolyser
ITM Power are providing the 0.5 MW electrolyser to turn electricity into hydrogen.
It’s only a small one, but this is about proving the technology.
Walking To Liverpool Street Station
I took these pictures yesterday, as I walked from my home to Liverpool Street station.
I had intended to buy the latest edition of Modern Railways at W H Smith’s in the station, but it was shut.
A Design Crime – The Average Smoke Detector
On Saturday Evening, the smoke detector in my bedroom decided to go off.
I was able to silence it about three times, but it refused to go off permanently.
I then decided to take it down, by standing on the bed.
Unfortunately, I slipped and broke the detector.
It is not the first altercation, I have had with the cheap and nasty smoke detectors in this house, which were probably bought in Istanbul market for a few pence.
- In my view, there is a need for a superior type of smoke detector wired into a building in a better way.
- It should be possible to replace a failed detector, like I had on Saturday in a simple operation without any tools.
- There should also be a master switch in the house, that switches off all the smoke detectors.
- Instructions on how to deal with the smoke detectors in case of failure should be in an obvious place in the house, like on the door of the meter cupboard.
Smoke detectors are too important, to be designed down to the cheapest possible station and most are a true design crime.
Marks And Spencer In Dalston Was On The Ball
This morning, I walked to Marks and Spencer in the Kingsland Road for essential supplies.
I got more than I needed and now have enough food in the fridge and my cupboards for the next ten days.
The hold-up in the store were the tills, but one of the assistants had taken control of the situation, by marshalling customers to spare self-service tills, scanning goods and helping to get the customers out of the store as fast as possible.
It was real East End spirit in action.
Remember that the BBC soap, was nearly shot in a real square close to Dalston and in some ways the chivvying and banter could have been transposed.
Is EastEnders dealing with COVID-19? I doubt it!
This Is My Second Lockdown
I can’t be the only person, but in the 1970s, I has locked myself away for nearly a year before. I did it to write the first version of the Project Management software; Artemis.
There are some differences between my situation then and my situation now.
- My wife was alive then and we saw each other for perhaps two days a week.
- I could drive and I occasionally went down the Clopton Crown for the odd pint and meal!
- I hadn’t been diagnosed as a coeliac, as that happened in 1997.
- There was no Internet or social media.
- There was no Radio 5 Live.
- I am a better cook now, than I was then.
- I am within walking distance of a Marks and Spencer Simply Food store.
I think the rules for surviving are as follows.
- Eat and drink enough.
- Have entertaining radio or television on.
- Break the day up with a bit of exercise.
- Get a good night’s sleep.
- Arrange good weather.
Let’s hope this lockdown turns out as well as the last.
Proudly South African Hydrogen Breakthrough With Shell’s Backing
The title of this post, is the same as that of this article on Creamer Media’s Mining Weekly.
This is the introductory paragraph.
At this time of huge coronavirus uncertainty, the chests of a group of engineers here must surely be bulging with pride following their major Proudly South African world breakthrough that could speed up the global deployment of hydrogen as a competitive universal and environment-friendly energy carrier.
I think it got a bit jumbled in the typing.
Reading the article it does seem that various developments are coming together in South Africa.
- A much simple electrolyser to produce hydrogen.
- South Africa’s platinum for catalysts.
- Large amounts of renewable energy.
The aim is to produce hydrogen at a comparable price with petrol.
This paragraph stands out.
South Africa has the combined solar and wind potential to produce competitive hydrogen, which can meet the world’s new environmental requirements.
The article talks about exporting hydrogen to Japan.
Conclusion
South Africa is a country that needs all the good news it can get.
This looks like it could be some of the best.
But how many other hot countries can take advantage of what looks like a breakthrough in the electrolysis of water to produce hydrogen for a fuel?
My Daily Exercise
My father always said I was born lucky!
When I bought this house in Dalston after my stroke, I bought it because of the location.
- There are four London Overground stations within walking distance.
- Four bus stops are within a hundred metres, which are served by five bus routes, one of which goes to King’s Cross, St. Pancras and Euston
- There are more than ten bus routes within walking distance.
- I have three bus routes to and from the Angel for the shops and Chapel Market, where my paternal grandmother, used to shop before the First World War.
- If I walk the other way, there was the rather run down Kingsland Road with a Sainsbury’s and lots of unhealthy takeaways.
But then Marks and Spencer opened a Simply Food store in the Kingsland Road by Dalston Kingsland station.
- It is about a fifteen minute walk from my house.
- It has a full range of their gluten-free food.
- It stocks everything I need regularly.
It was certainly my luck, that they opened this store.
Today, I took my daily exercise by walking to the store and bringing home enough food for a couple of days.
- Is this killing two birds with one stone?
- The walk along the Balls Pond Road was notable because there was only little traffic and few pedestrians on one of East London’s main arteries.
- A sizeable proportion of the shops were shut.
It was also very breezy and was this good to protect me from COVID-19, by blowing it away?
Walking Through De Beauvoir Town
I took these pictures as I walked through de Beauvoir Town, as I walked through today on my way to and from the doctor’s to get my hand dressed.
There wasn’t many people about and I perhaps only got within three metres to one person and her dog.
What would help would be a few seats, so that elderly people like me could take a break.
