Grønt brint i krise: Skepsis til dyre teknologier vokser!

Boxberg, Deutschland - I de senere år har diskussionen om grønt brint spillet en central rolle i energiovergangen. However, there is currently skepticism compared to this technology, such as oekonews.at reports. The production of green hydrogen (H2) is carried out using electrolysis from green electricity, whereby the high costs of around 3 to 6 €/kg compared to fossil hydrogen, which costs only € 1.5 to € 2/kg, are often considered a hindrance. Kritikere hævder, at ressourcerne skal investeres bedre i mere praktiske alternativer til energiovergangen.

Et konkret eksempel på dette er de mislykkede brintprojekter i kulgruppen Leag i Lusatia. Denne udvikling har allerede ført til politikere og repræsentanter for fossile grupper i stigende grad afværger sig fra brintprojekter. I denne sammenhæng diskuteres SMR -atomstyrke også som en mulig alternativ teknologi.

teknologiske udfordringer og perspektiver

Grønt brint betragtes ikke desto mindre som en nøgleteknologi for en klima -neutral industri. The company Thyssenkrupp Nucera, leader in the area of electrolysers, has announced that it will provide significant amounts of green hydrogen by 2025. The development of scalable 20 MW electrolysis modules (SCALUM®) could help to significantly reduce the production costs, as techzeitgeist.de. Et 300 MW -system er allerede udviklet til CEPSA -energileverandøren, som antages at producere 47.000 ton grønt brint årligt.

The various electrolysis technologies, including alkaline electrolysis (AEL) with efficiency of 65–70 % and proton exchange membrane electrolysis (PEM) with up to 80 %, offer different approaches to improve efficiency in hydrogen production. Furthermore, high-temperature electrolysis (SoEC technology) promises efficiency over 80 %, which could reduce electricity requirements by up to 30 %.

markedsforhold og statsstøtte

For at fremme udviklingen af markedet for grønt brint er betydelig statsstøtte vigtig. The Federal Ministry of Economics is planning to set up an electrolysis capacity of 40 GW in Germany by 2030 and invests over 6 billion euros in corresponding programs. The EU aims to generate at least 10 million tons of green hydrogen by 2030, while the challenges by raw materials and a shortage of skilled workers should not be underestimated (bundeswirtschaftsministry.de).
