As with any technology, the key to cost reduction is the rate at which the technology is deployed, but the hydrogen economy is moving forward slowly
More use of hydrogen in energy systems is increasingly held up as important to the transition away from use of fossil fuels, but it is important to analyse exactly where hydrogen is genuinely needed as a clean energy solution and how the necessary technological advances will be funded
LITTLE FUNDING
Despite plenty of hype about its potential as a solution to help the world decarbonise, green hydrogen has received relatively little funding compared to other renewable energy solutions. Only about 4% of the energy research budgets of International Energy Agency members was spent on hydrogen and fuel cells in 2018. Over 20% went to nuclear energy and around 16% to renewables
FUTURE GROWTH
Increasing volumes of cheap renewables, falling costs of electrolysers and new solutions are likely to boost hydrogen’s role in the clean energy transition, though only for specific uses. Some forms of transport, in particular trains and ferries, could be key beneficiaries as they struggle to decarbonise
KEY FIGURE
At a typical cost of €50 a megawatt hour for wind and solar in Europe feeding an electrolyser costing €900 a kilowatt hour, the hydrogen produced would cost around €90 a megawatt hour, far from competitive with the price of European natural gas at €12/MWh in January 2020. The levelised cost of electricity from onshore wind in Europe ranges from around €50/MWh to $100/MWh ...

The huge scale of offshore wind farms being built in northern Europe is bringing a new understanding of how much electricity can be gleaned from the wind on land and at sea
Much as in the energy transition debate, the big question is who pays for carbon removal
Questions around definitions, targets and the funding of green hydrogen in Europe still need answering
Europe’s offshore wind revolution requires a more integrated approach
Efficiency measures have cut greenhouse gas emissions in the shipping industry, but if the sector is to be part of the climate solution, radical action to adopt new cleaner fuels is the only answer
Trucks and ships could be two means of transport running on hydrogen gas, produced using electricity, in the coming years
The Northern Netherlands has won a €20 million EU grant to become Europe’s flagship green hydrogen project. The former natural gas region will lead Europe — and the rest of the world — in the energy revolution required by the Paris climate agreement, says Nienke Homan, regional minister in the Province of Groningen
