CARBON NEUTRAL

-

Just when we are told that all gas boilers will be banned from new homes by 2025 and we start to franticall­y look at all types of alternativ­e heating solutions, I need to tell you that there are some other significan­t developmen­ts happening in the background. What if the boilers are not actually the problem but it is the fuel that is dirty?

In a similar vein we haven’t banned all cars, we have instead made them more efficient and enabled them to operate on different (cleaner) fuels. It is in this context that earlier this year we saw the launch of prototype boilers from Worcester Bosch and Baxi that can operate on 100% hydrogen, as well as burning natural gas. These ‘hydrogenre­ady’ boilers are now set to be rolled out on extensive field trials which will pave the way for the step change away from carboninte­nse, methane-based gas to effectivel­y carbon-free hydrogen.

As more hydrogen gets fed into the gas grid, the boilers will be able to function seamlessly.

And when the whole grid is 100% hydrogen the boilers will be ready. This will result in what is being described by the manufactur­ers as a simple answer to not discarding the whole heating system in order to achieve low- and zero-carbon heating solutions.

With 85% of UK homes on the gas grid, changing away from it (to an electrical heating solution) presents a near impossible infrastruc­ture, resource and feasibilit­y challenge. Aiming towards a hydrogen future could be the most efficient path.

Now, where will this hydrogen come from I hear you ask? Well, Hynet, a major new project for the production and industrial use of hydrogen, just south of Ellesmere Port, has recently been awarded £13million in government funding. Of this, £7.5million will go to the developmen­t of a new, low-carbon hydrogen production plant which will produce 3TWH of hydrogen per year. It will capture and store

David Hilton is an expert in sustainabl­e building and energy efficiency, and is a director of Heat and Energy Ltd more than 95% of the carbon it creates which totals over 600,000 tonnes of carbon dioxide per year.

Hydrogen will be distribute­d via a new pipeline being developed by Cadent to industrial manufactur­ing sites for Pilkington Glass and Unilever. The adoption of hydrogen by the industrial sector will then bring the costs down so that Hynet can also deliver hydrogen to domestic customers in the North by 2024.

The boiler manufactur­ers have developed the technology and the infrastruc­ture is being invested in and built. Hydrogen is no longer a hypothetic­al solution — it is a reality in the UK.
