The Prague Post - Denmark inaugurates rare low-carbon hydrogen plant

Using eight electrolysers powered by solar and wind energy, the HySynergy project will produce around eight tonnes of hydrogen a day in its first phase, to be transported to a nearby refinery and to Germany.

Hydrogen has been touted as a potential energy game-changer that could decarbonise industry and heavy transport.

Unlike fossil fuels, which emit planet-warming carbon, hydrogen simply produces water vapor when burned.

But producing so-called "green hydrogen" remains a challenge, and the sector is still struggling to take off in Europe, with a multitude of projects abandoned or delayed.

Originally scheduled to open in 2023, the HySynergy project, based in Fredericia in western Denmark, has suffered from delays.

According to the International Energy Agency (IEA), only four plants currently produce low-carbon hydrogen in Europe, none with a capacity greater than one megawatt.

HySynergy will initially produce 20 megawatts, but "our ambitions grow far beyond" that, said Jakob Korsgaard, founder and CEO of Everfuel, which owns 51 percent of the project.

"We have power connection, we have land, we have utilities starting to be ready for expansions right here, up to 350 megawatts," he told AFP.

With the technology not yet fully mature, hydrogen often remains far too expensive compared to the gas and oil it aims to replace, mainly due to the cost of electricity required for its production.

Outside of China, which is leading the sector, the "slower-than-expected deployment" is limiting the potential cost reductions from larger-scale production, the IEA said in recent report.

It added that "only a small share of all announced projects are expected to be operative by 2030."

"The growth of green hydrogen depends on the political momentum," Korsgaard said, urging European Union countries and politicians to push for ambitious implementation of the EU's so-called RED III renewable energy directive.

The directive sets a goal of at least 42.5-percent renewable energy in the EU's gross final consumption by 2030, and highlights fuels such as low-carbon hydrogen.
