The interest in hydrogen has resurged due to technological advancements and the need to combat climate change. Europe, in line with the European Green Deal, sees hydrogen as a crucial element in achieving carbon neutrality by 2050. While hydrogen usage is currently modest and often based on fossil fuels, there is a push to decarbonize its production and expand its applications in industries like steel and chemicals. The EU envisions clean hydrogen as a key component in reaching its climate goals, with substantial investments expected in the coming decades. However, challenges such as cost-competitiveness and energy efficiency need to be addressed. Countries like Finland, the Netherlands, Belgium, Germany, and the U.K. are actively investing in green hydrogen production to meet targets and transition to a low-carbon economy.
