"Hydrogen is no more the wonder gas than CO2 is the opposite. Apart from being very expensive to produce using so-called ‘green’ methods, it’s running into various obstacles elsewhere, such as absence of infrastructure....
    "Europe’s time spent sleepwalking to the tune of hydrogen lobbyists – draining funds and political capital for far too long – appears to be coming to an end as leaders come face-to-face with physical realities....
    " The European Commission estimates that to produce, transport and consume 10 million tonnes of renewable hydrogen domestically, investment worth up to €471 billion will be necessary.
    "For the odourless gas to be climate-friendly, it must be produced through electrolysis using renewable electricity. To avoid electrolysers taking up all the green power in the grid and boosting demand for coal power, two-thirds of the €471 billion will have to be invested into additional renewables.
    "To meet the second half of the EU’s hydrogen targets – 10 million tonnes of imports – will require another estimated €500 billion.
    "That amounts to a €1 trillion dream to get the hydrogen economy from non-existent to infancy into 2030, and the spending certainly wouldn’t end there....

    "Finally, what will all that hydrogen be used for?

    "Once, lobbyists painted a rosy picture of an entire economy running on hydrogen. But hydrogen cars proved a non-starter while heating with hydrogen has thankfully been banished from people’s minds.... Politicians find the idea of hydrogen as a form of long-term energy storage tempting.... [Yet] Industry demand is projected to be far below the EU’s lofty targets....
    "After years of hydrogen hype, Brussels may just focus on electricity – the true fuel of the future."
