In 2020, pilot projects began using green hydrogen in metal refining processes to reduce carbon emissions in iron and steel production. This innovative approach aims to address environmental concerns associated with traditional methods that rely on fossil fuels. The adoption of green hydrogen represents a significant step towards sustainable industrial practices and highlights the ongoing efforts to combat climate change in heavy industries.

The pilot projects for green hydrogen in metal refining in 2020 inspired contemporary poetry focused on sustainable futures. Poets began to explore themes of environmental responsibility and innovation, reflecting the urgent need for climate action and the potential for technology to address ecological challenges.
