Our gas boilers are a leading cause of climate change.
Burning natural gas to rut our homes and hot water releases carbon into the atmosphere. And this is a leading cause of climate change. So to tackle this, the government is planning to plough to hydrogen. Information technology can be added to the current gas network and sent to our homes in the same way as natural gas only called-for it doesn't produce carbon. This makes it a possible alternative to natural gas.
Let'southward accept a look at whether hydrogen is a good option for home heating.
What is hydrogen?
Hydrogen, nitrogen and oxygen make upwards 75% of the universe and form the foundation of much of our planet's life.
Hydrogen is found in almost all institute thing and h2o. The sun is too made up of a lot of hydrogen, simply it is and then calorie-free that it evaporates from the surface of the earth through the heat of the lord's day's rays.
Hydrogen is the virtually unproblematic of all our elements being made up of only i proton and one electron. This ways that in virtually scenarios it doesn't be by itself but is combined with other elements (e.thousand. h2o or Water is 2 parts hydrogen to one role oxygen). All the same, hydrogen is a clean source of energy which, if nosotros can extract information technology from water, natural gas or biomass, can be used to ability and heat our homes.
How hydrogen is made
There are two methods used to extract hydrogen: electrolysis (light-green hydrogen) or steam-methane reforming(grayness or blue hydrogen).
Electrolysis involves passing a high current of electricity through h2o to split the oxygen and hydrogen atoms.
It sounds simple enough, only this is a plush procedure due to the amount of electricity needed. And to create the electricity, fossil fuels (e.yard. natural gas, oil or coal) are burned which produces carbon emissions. If the electricity used in electrolysis comes via solar panels, wind farms or hydropower then we can avert these carbon emissions.
Steam-methyl hydride reforming is the process of separating carbon and hydrogen in methane. It is the method used near unremarkably at the moment because hydrogen can be extracted in large quantities, but it results in the emission of carbon dioxide and carbon monoxide. Both of these gases are harmful to our atmosphere and will contribute to global warming.
Even so, it is possible to capture the carbon emitted during the process of producing hydrogen with Carbon Capture Utilisation Storage (CCUS) systems which would prevent the carbon from being released into the atmosphere.
Advantages of hydrogen energy
Hydrogen is renewable
Hydrogen is a renewable energy source which means we cannot run out of it, at to the lowest degree non on a human timescale. It's a rich source of energy which is all around us.
Hydrogen is a make clean energy source
When nosotros burn hydrogen no harmful byproducts are released into the atmosphere. In fact, in one case hydrogen has been used as an energy source, information technology tin can exist converted to drinking water for astronauts.
Information technology's non toxic
Hydrogen doesn't crusade harm to homo health unlike nuclear energy or natural gas.
Highly efficient
Hydrogen is incredibly dense in free energy and is able to provide a lot of power. It is 3 times more powerful than most fossil based fuel sources so less hydrogen is required to perform the same tasks. This is why hydrogen is used in space exploration to fuel spaceships, aeroplanes, boats, cars and fuel cells.
Information technology would speed up the use of renewables
For hydrogen to be truly carbon neutral any electricity used to brand information technology must come from renewable energy sources.
In the government's Hydrogen Strategy, it's stated that off-shore wind generation will be making 4x more energy by 2030 to back up demand for hydrogen.
Create thousands of jobs
Turning to hydrogen would create thousands of new job opportunities. The regime has estimated that turning to hydrogen for home heating would create 9,000 jobs by 2030 and 100,000 by 2050.
Will cost the same as gas boilers
A business with moving to depression-carbon heating is that homeowners will have to pes the bill. But the biggest boiler manufacturers: Baxi, Platonic Vaillant and Worcester Bosch have all promised to proceed hydrogen-prepare boilers at the same price equally gas boilers.
Disadvantages of hydrogen energy
Hydrogen is volatile
Because of its high energy content, hydrogen gas is a highly flammable and volatile substance which makes it a risky fuel to work with.
Hydrogen energy is expensive to produce
Both steam-methane reforming and electrolysis are expensive processes which prevents a lot of countries from committing to mass production. Inquiry and trials are in process to try and detect a inexpensive and sustainable way to produce plenty hydrogen without contributing more than carbon into the atmosphere.
Hydrogen energy is hard to shop
Hydrogen is a much lighter gas than gasoline which makes it hard to store and transport. To exist able to store it we demand to compress it into a liquid and store information technology at a low temperature. The loftier amounts of force per unit area needed to store hydrogen makes it a difficult fuel to transport in big quantities.
Hydrogen can be unsafe
Hydrogen is incredibly flammable which makes information technology a dangerous fuel if not handled correctly. There is also no smell to hydrogen so sensors are required to observe leaks.
Making hydrogen tin can produce carbon
In that location are many ways of making hydrogen. And some of the produce carbon.
In the Britain, nosotros're likely to use Steam Methan Reforming (SMR) where steam reacts with metane to make hydrogen. But as well carbon.
Fortunately, it is possible to capture this cabron through Carbon Capture Utilisation and Storage (CCUS). Then once captured information technology can be used by other industries – like calculation fizz to drinks.
This method is known every bit blue hydrogen – find out nigh all the colours of the hydrogen rainbow.
Unproven technology
Hydrogen holds a lot of the right answers when it comes to cleaning up home heating. However, we can't switch to putting hydrogen in the gas network overnight.
Earlier we tin can start using hydrogen, the engineering needs to be tested. And then hydrogen trials are being set in areas across the country.
The government has said at that place will exist a neighbourhood trial by 2023, large hydrogen hamlet by 2025 and possibly a town pilot by 2030.
Can emit nitrous oxide when burned
When hydrogen is burned in a particular way (based on temperature, size of the flame and airflow) nitrogen oxide (NOx) can be emitted. This is gas causes air pollution.
However, the same can be said of our current gas boilers which have been designed to produce depression NOx emissions. So the same would need to be the case for hydrogen boilers.
Could hydrogen exist used in dwelling house heating?
At the moment the vast majority of UK homes rely on fossil-fuels for heating. Mainly natural gas and oil boilers.
To reduce carbon emissions in line with government targets and fight climatic change, we need to change the way we heat our homes. And hydrogen is a strong contender.
Moving from natural gas to hydrogen would let us to keep heating our homes with boilers. Saving usa from the mammoth task of replacing them all with renewable heating systems like air source heat pumps.
Gradually nosotros could increase the levels of hydrogen supplied to homes. So we'd begin with a hydrogen blend of twenty% hydrogen with natural gas. This would then be increased to 100% hydrogen over time.
The main benefits existence:
- Hydrogen is highly efficient (1kg of hydrogen can produce as much energy as two.8kg of natural gas)
- There would be no carbon emissions from hydrogen boilers (only produce water vapour and heat)
- Hydrogen could be used in existing gas grid infrastructure
- Boilers are a familiar heating system for homeowners, unlike renewable heating systems (rut pumps and solar)
So when could it happen?
The earliest we could run into hydrogen added to the gas network is 2026. But no decisions have been made nonetheless.
If we are to move to a hydrogen future and so nosotros'll all need hydrogen-ready boilers. Most condensing gas boilers can run on a hydrogen blend of xx% hydrogen but not 100% hydrogen.
Worcester Bosch and Baxi have adult prototypes of hydrogen boilers. These boilers still piece of work with natural gas but after a short visit from a heating engineer they can piece of work on a 100% supply of hydrogen.
Find out which boilers are certified to run on a hydrogen blend in our guide to Hydrogen Boiler Manufacturers.
So, is hydrogen heating a feasible pick?
There is a strong instance for hydrogen playing a big office in the futurity of habitation heating.
However, which switching from natural gas to hydrogen may sound elementary plenty it's far from it. Producing hydrogen is currently expensive and the procedure can emit carbon. Which defeats the object of swapping to a hydrogen network somewhat.
Co-ordinate to industry experts, hydrogen has a major function to play in the futurity of home heating. Hydrogen heating trials are already taking place in the Britain where a combination of hydrogen gas and natural gas is already in utilize in some areas. The authorities is planning more trials over the side by side decade: neighbourhood trial by 2023; large hydrogen hamlet by 2025 and perhaps a hydrogen town past 2030.
