- Hydrogen is seen as a viable long-term solution that can reduce emissions in the most carbon-intensive sectors
Decarbonising the global economy by mid-century is crucial in the fight against climate change, which requires a major overhaul in the world’s energy systems.
Hydrogen has emerged as a viable long-term solution that can reduce emissions in the most carbon-intensive sectors, including power generation, ground, sea and air transport and steel and cement.
To make the zero-emission fuel commercially viable, much work and investment lies ahead to enhance efficiency, reduce costs and scale up deployment.
