Abstract: This analysis aims to prove the irreversibility of the energy transition to clean energy system without emissions and the key role of 'green' hydrogen in this transition. Catastrophic global warming associated with greenhouse gas (GHG) emissions threatens the continued existence of our civilisation and obliges humanity to make the necessary global decisions as soon as possible. Today, in order to solve important environmental and energy problems and reduce the risk associated with the enrichment of the atmosphere with carbon dioxide, the world is increasingly using 'green' hydrogen as a universal environmentally friendly energy source. The use of 'green' hydrogen for Ukraine is urgently needed as it allows large-scale use of renewable energy sources (RES) instead of obsolete and inefficient existing traditional generating capacities. It is better to start implementing hydrogen technologies as soon as possible, recognising that an imperfect start is likely better that adopting 'wait and see' approach, which could worsen the situation in the energy sector, and above all, environmental issues.

Keywords: hydrogen; 'green' hydrogen; 'blue' hydrogen; renewable energy; fossil fuels; climate changes; greenhouse gas emissions; strategy; roadmap; storage; technology; fuel cell; Ukraine.
