    Why hydrogen could be the future of

    green energy

    Hydrogen’s potential
    Hydrogen has the potential to decarbonise
    electricity generation, transport and heat.
    That’s because when produced by
    electrolysis - using electricity to split water (H2O) into hydrogen and oxygen - hydrogen does
    not produce any pollutants.
    Perhaps the best-known use for hydrogen currently is in transportation. With electric
    vehicles, drivers are often concerned about their range and the time it takes to recharge.
    Fuel cell electric vehicles, which run on hydrogen, avoid these concerns, as they have a
    longer range, a much faster refuelling time and require few behavioural changes.
    Hydrogen can also be used to heat our homes. It can be blended with natural gas or burned
    on its own. The existing gas infrastructure could be used to transport it, which would avoid
    the grid costs associated with greater electrification of heat.

    Once produced, hydrogen could also act as both a short and long‐term energy store.
    Proponents suggest that surplus renewable power – produced, for example, when the wind
    blows at night – can be harnessed and the hydrogen produced using this electricity can be
    stored in salt caverns or high-pressure tanks. Earlier this month a report by the Institution of
    Mechanical Engineers called for more demonstration sites and a forum in which to discuss
    hydrogen’s long-term storage potential.
    Research challenges
    Hydrogen clearly has several potential uses, but more research, particularly in production
    and safety, is needed before we can use it at scale.
    Currently, almost all of global hydrogen (96%) is produced by reforming methane (CH4), a
    process which ultimately produces carbon dioxide. To be sustainable, this production
    method would need to be deployed with carbon capture and storage, which is itself in need
    of further development.
    Electrolysis produces no carbon emissions. Yet the amount of hydrogen that can be
    produced using this method depends on the cost and availability of electricity from
    renewable sources. A report by the Royal Society suggests that electrolysis may be better
    suited for vehicle refuelling and off-grid deployment rather than for large-scale, centralised
    hydrogen production.
    Concerns about the safety of using hydrogen also need to be addressed. A report by the
    UK’s National Physical Laboratory noted two priority safety issues when transporting
    hydrogen in the grid and combusting it for heat. When hydrogen is combusted, you can’t see
    the flame, so there needs to be a way of detecting whether it is lit. Hydrogen would be
    transported and stored at high pressures, so we need to find an odorant that works with
    hydrogen so that people can detect leaks.
    On the horizon
    The appetite to explore hydrogen as an energy vector is growing at pace, but reports need to
    be followed up with action.
    The research challenges that hydrogen poses re not unique to one country or company, so
    collaboration in developing and trialling technologies will be critical. Both businesses and
    governments seem to recognise this. Last year the Hydrogen Council, a group of
    multinational companies with a ‘with a united vision and ambition for hydrogen to foster the
    energy transition’, was launched at the World Economic Forum in Davos. And earlier this
    year governments have also agreed to collaborate on the topic, launching a new theme
    under the Mission Innovation partnership focussed on bringing hydrogen technologies closer
    to market.
    Hydrogen is not the panacea - but then neither is solar PV, offshore wind or battery storage.
    We need several and varied technologies if we are to decarbonise successfully. Hydrogen
    looks very likely to be one of them
