The article discusses Equinor's scenario outlooks on the role of clean hydrogen in global energy systems by 2050. The Walls scenario projects a substantial demand increase for clean hydrogen, with a focus on industry and transport but limited application in the power sector. Europe advocates for hydrogen, while North America and Asia-Pacific show potential as hydrogen leaders. In the Bridges EP23 scenario, clean hydrogen becomes a key player in decarbonisation efforts, especially in eliminating emissions from gas-fired power generation. China emerges as a significant market for hydrogen, with a shift towards green hydrogen production using renewable energy. The article emphasizes the challenges of clean hydrogen adoption, including high costs, infrastructure hurdles, and competition for renewable resources. Despite the potential benefits in decarbonising hard-to-electrify sectors, the trajectory of hydrogen adoption remains uncertain due to economic, technical, and policy factors. Overall, the outlook is positive on the role of hydrogen in the energy transition, highlighting its importance in achieving global decarbonisation goals.
