In the medium to long term, centralised fossil fuel-based production of hydrogen, with the capture and storage of CO2, could be the technology of choice. However, the capture and storage of CO2 is not yet technically and commercially proven. Further R&D on the processes of absorption and separation are required.
Storage strategies encompass compressed gas, liquid, and solid-state methods, each with unique characteristics and use cases. Mainstream hydrogen applications involve fuel cells, hydrogen combustion, and hydrogen-powered engines, demonstrating substantial potential for enhanced energy efficiency and reduced environmental pollution.
