This paper analyses the current development status of hydrogen production technologies and projects global demand growth through 2050. Production costs and CO2 emissions per kilogram of hydrogen are identified as key factors influencing the adoption of hydrogen technologies. While fossil-based methods currently offer cost advantages, electrolysis and biological processes demonstrate superior performance regarding CO2 emissions. Provided that sufficient investments are made, the cost of renewable energy production ...

In light of the pressing need to achieve climate neutrality in the energy sector, the European Union seeks to identify strategies that will enhance and diversify its green energy supplies. As a renewable energy source, green hydrogen promises to offer a viable alternative to fossil fuels where green electricity may be insufficient or inaccessible. This is why the production and supply of this innovative energy carrier is becoming a significant focus in EU politics and research. This article examines and compares p...
