Alternative fuel vehicle[edit]
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[edit]
‘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.[1]
Green hydrogen[edit]
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.
