    What is hydrogen?


    A guide to hydrogen energy

    For those who remember school science lessons, you’ll know hydrogen as the first element on the periodic table. Hydrogen itself is never found on its own, rather as part of more complex molecules, like water.

    The great thing about hydrogen is that when it’s burned, no carbon emissions are released. And it can be used for heat, power and even fuel for large vehicles like HGVs. Hydrogen holds a lot of energy so it’s great for transporting large amounts of energy to where it’s needed.

    But hydrogen isn’t found naturally on its own, it has to be made either through electrolysis or through reforming methane. Both methods can be used in a way that keeps carbon emissions to a minimum.

    With much of the UK looking to switch to greener, sustainable energy in the future, we’ve put together some important information to answer your hydrogen questions and explain how we’re playing our part to achieve the UK government's ambition of net zero by 2050.


    The many uses of hydrogen: what is hydrogen used for?

    When it comes to energy, hydrogen is one of the cleanest forms you can find; when it's burned or used in a fuel cell for a vehicle, no carbon emissions are released. This means that increased use of hydrogen as a fuel will mean cutting down on carbon emissions produced from conventionally used fossil fuels such as gas and coal. In fact, using a hydrogen fuel cell in an electric vehicle is two to three times more efficient than using a combustion engine.


    Why hydrogen energy for the UK?

    In 2019, the UK emitted 351.5 million tonnes of carbon dioxide from the use of fossil fuels, accounting for 81% of the UK’s greenhouse gas emissions.

    It's widely accepted now that this needs to stop and soon. The way we heat our homes, run our vehicles and power our industries have all contributed to climate change. We're looking for solutions that balance environmental targets with customer needs.

    In order to supply the increasing energy demands of the UK, we will need a combination of approaches. Renewable electricity from wind and solar can do a lot. But to reach 100% net zero we will certainly need hydrogen as well, alongside better insulated homes and smarter use of energy. We aim to see electricity and green gas working together in partnership.

    What to keep in mind

    To achieve net zero, most homes will need new or different heating systems as well being much better insulated with controls for energy use. There are a number of options available including heat pumps, district heating systems, hybrid solutions and hydrogen. The Government has yet to set out how much of each is needed and where.

    Every energy choice means change

    Whatever the government decides to do about future energy choices, there will need to be a great deal of change eventually. Increasing the capacity of the electricity grid or building hydrogen production facilities are both large projects but the gain will be a sustainable future for us all.

    What will the green recovery cost you?

    How the investment we've talked about above is reflected in utility bills or income taxes is something that the Government will decide. It is clear, though, that this investment has to be made if we are to have a sustainable future.

    We need ALL types of energy

    Finding the right solution for a greener future is not a competition between electricity and gas. We will need both (and nuclear and other options) to supply customer needs and reach net zero. While renewable electricity will play a massive role, experts now agree that hydrogen will also be needed to get us to net zero.

    Our Future of Gas projects

    We are involved in projects looking at all aspects of using hydrogen in future - from billing and pipelines to blending and customer attitudes.

    What are we doing?

    We’re involved in several hydrogen projects in partnerships with the energy sector.

    The three main areas we lead on are blending, industrial power and decarbonising heavy transport.

    Blended Hydrogen
    Industrial Decarbonisation
    Decarbonising heavy transport
    Making our network green gas ready

    What is hydrogen blending and why do we need it?

    As the UK works towards reaching net zero carbon emissions by 2050, it’s important to take action as soon as possible, starting to decarbonise heating and replace natural gas with a greener alternative. At Cadent, we believe the best option for this is hydrogen.
