Once energy users receive 80% of their energy from renewable sources, it becomes very challenging to decarbonise the final 20%, said Vibrant Clean Energy founder George Harvey. Processes like manufacturing cement and powering large passenger aircraft are extremely difficult to run with carbon-free fuels. However, a range of natural carbon-based fuels made from biomass or natural gases could be used to replace oil, gasoline or plastics. Additionally, carbon-free fuels including compressed air, liquid nitrogen, hydrogen and ammonia can be used as an alternative to fuel if handled correctly.
