Hydrogen strategies and drought are both high on Europe's agenda, and where they meet a question keeps coming up: will hydrogen production drain water supplies? Mostly not, according to a report published by the European Commission's Joint Research Centre…

Hydrogen is the most abundant element in the universe and has long been seen as one of the most promising clean energy carriers – using it produces only water and heat, not carbon dioxide. The flaw is that about 95% of the hydrogen produced today still comes…

This is the third article in our four-part series on hydrogen. In the first part we introduced the basics of hydrogen and mapped the global race; in the second we examined production technologies. This part looks at what hydrogen is really good for – where it…

…Zeewolde, a 322 MW facility in the province of Flevoland made up of 222 turbines. A hydrogen-iron flow battery with a capacity of 20 MW (200–800 MWh) will be installed at Zeewolde, considered Europe's largest onshore wind farm. The project shows both…

Hydrogen is one of the most talked-about players in energy debate. Strategy documents, EU regulations, oil company press releases and decades of promises from research institutes all suggest that hydrogen is the fuel of the future. Yet in 2024 less than 1% of…

In the first part of our series we outlined why hydrogen has become one of the key elements of the energy transition and how the global race to use it stands. But one question remained open: if 83% of hydrogen is grey – that is, fossil-based – what can it have…

…article opens a new four-part series. The series takes you through the whole world of hydrogen: from production technologies and the role of water to its applications, all the way to why this element, which could solve so much, has not yet become part of…

Dosing iron into the digester is one of a biogas plant's main defences against hydrogen sulphide, but iron chloride, iron hydroxide and iron oxide behave very differently – and reactivity matters more than the price per kilo.

…Europe programme, has shown that a microwave-heated fluidised reactor can produce hydrogen from raw biogas almost three times more efficiently than electrolysis – while the solid carbon by-product can be locked away in soil for the long term.

…would be excluded. The approach is technology-neutral on paper. Biomethane, green hydrogen and synthetic methane could all count towards the gas quota, and biodiesel and synthetic liquid fuels towards the oil quota, as long as they meet the…
