The article discusses the rising importance of green hydrogen in the global energy landscape, particularly in Europe. While hydrogen currently plays a limited role in the energy mix, efforts are being made to transition towards carbon-free hydrogen production, mainly utilizing renewable sources. The decreasing costs of renewables are facilitating the growth of green hydrogen, aligning with the goals of energy independence and reduced greenhouse gas emissions. The European Commission's REPowerEU plan highlights the ambition to achieve 10 million tonnes of renewable hydrogen production by 2030, aiming to lessen dependence on Russian fossil fuels. However, the green hydrogen sector is still in its early stages, with the need for further projects and infrastructure development. The article emphasizes the wide-ranging applications of hydrogen in industrial decarbonization, including sectors like oil refining, chemical production, and steel manufacturing. The use of hydrogen presents an opportunity to transform existing industries and infrastructure towards a low-carbon future. Overall, the article portrays a positive sentiment towards the potential of green hydrogen in fostering sustainability, energy transition, and circular economy practices.
