Researchers at Tampere University and Tampere University of Applied Sciences in Finland are at the forefront of developing innovative solutions for sustainable hydrogen production. Hydrogen, as the world's lightest element, poses challenges in production and storage due to its energy-intensive processes and high flammability. Despite these challenges, there is a growing recognition of hydrogen's potential as a clean energy carrier to combat climate change and reduce fossil fuel consumption. Experts highlight the importance of transitioning to electric alternatives powered by renewable energy and utilizing green hydrogen in sectors like long-distance transportation and heavy industry. The article discusses two primary uses of hydrogen in energy production: burning for immediate energy or producing e-fuels like e-methanol and e-methane. By utilizing renewable energy sources for hydrogen production, carbon dioxide emissions can be minimized, making the consumption of hydrocarbon-based e-fuels carbon-neutral. Finland stands out as a potential global leader in the hydrogen economy due to its favorable conditions for wind farms, robust power grid, and expertise in hydrogen technologies. The researchers at Tampere University are involved in diverse and multidisciplinary research, focusing on enhancing hydrogen production efficiency, developing new materials for storage and transportation, and exploring artificial photosynthesis for chemical production. Additionally, the geopolitical perspective on hydrogen research addresses potential threats to critical infrastructure. Education is also emphasized alongside research, with Tampere University of Applied Sciences investing in hydrogen research and planning a large-scale project on hydrogen safety in collaboration with other institutions and energy companies.
