What is Hydrogen?
Hydrogen is an energy carrier which can be created at volume. Both blue and green hydrogen offer zero carbon heat at the point of use.
Blue Hydrogen - Is produced from natural gas, usually via Steam Methane Reforming (SMR) or Auto-Thermal Reformation (ATR), with carbon capture and storage.
Green Hydrogen - Is produced using renewable energy (such as wind or solar) for electrolysis to separate water into its component parts (Hydrogen and Oxygen). Using this process means that there are no carbon emissions, plus there is the opportunity to use inter-seasonal storage to make best use of surplus electricity from constrained renewable sources in summer months.
What will the transition to Hydrogen look like?
It is unlikely that 100% hydrogen deployment will role out much before 2030, and this will vary from region to region. As a result, stepwise developments will be required:
Step 1 - 20% Hydrogen Blend - It is expected that the first step will be to introduce a blend of up to 20% hydrogen into the gas network. 20% hydrogen blends have been successfully demonstrated using current natural gas boilers.
Step 2 - 'Hydrogen Ready' Boilers - The next phase is the introduction of 'hydrogen ready' boilers, which will be the bridging solution to the energy transition. 'Hydrogen ready' is defined as a boiler that can operate on natural gas at the point of installation and can then be converted to run on 100% hydrogen with a conversion kit, during its service life.
Step 3 - 100% Hydrogen Boilers - The last step will be boilers that are able to operate on 100% hydrogen at the point of installation.
Will I need to change my boiler?
You won’t need to upgrade your existing boiler until it comes to the end of its natural life. Hydrogen for widescale home heating is still a long way off so if you need to upgrade your boiler in the near future, you can be sure it will continue to work for it’s entire life before hydrogen fully replaces natural gas.
New boilers will however be needed for homes to use 100% hydrogen in the future. The benefit of a hydrogen-ready boiler is, it will fit in the same spot as your old one and manufacturers have committed to ensuring they will be the same price as a traditional boiler.
Manufacturers, including BAXi, are already making and testing hydrogen-ready boilers, which can be easily converted to use 100% hydrogen in the future.
Will Hydrogen cost most than natural gas?
Figuring out the cost of hydrogen gas when the technology is in its infancy is difficult at this stage. We do know it will fall as efforts across the industry to develop new technology ramp up. New technology always takes time to adapt. For example, the cost of harnessing wind power used to be unaffordable but today it is one of the cheapest forms of energy in the UK following years of investment and development. We see the same happening with hydrogen. We also know that developing a hydrogen economy right here in the UK will protect households from some of the fluctuating energy costs we’ve seen in recent months because the country will have control over its supply.
Once it’s up and running, domestic hydrogen will become more affordable over time. We are not the only country looking at hydrogen. The UK Government is already working with countries across Europe, the US, Australia and Chile to make sure hydrogen can be affordable to households with an aim of it costing around the same price as natural gas before the recent energy price crisis.
