Alternative fuel vehicle
Comparative assessments of conventional fossil and alternative fuel vehicles inform policy-making and consumer choice against the objectives and rationale for alternative fuel vehicles for their potential environmental, health, cost and security benefits.

Hydrogen economy
‘Blue’ hydrogen, made using SMR with carbon capture, amounted to 0.6% of global production. ‘Green’ hydrogen, produced using electrolysis of water using renewable power, comprised 0.2% in 2021.

The extent to which hydrogen will be used to decarbonise appropriate applications in heavy industry, long haul transport and long-term energy storage is likely to be determined by the evolving production costs of low- and zero-carbon hydrogen.

A 2022 Goldman Sachs analysis anticipates that globally blue and green hydrogen will achieve cost parity with grey hydrogen by 2030, earlier if a global carbon tax is placed on gray hydrogen.

Green hydrogen
The International Energy Agency has estimated that hydrogen, and hydrogen-based fuels such as green ammonia could comprise 10% of global final energy demand by 2050, consistent with meeting the goals of the Paris Agreement on limiting global warming to 1.5C.
