cars, trucks, and buses around the world, and more than 30,000 forklifts. In Paris, a fleet of more than 100 former diesel taxis are now fuelled by hydrogen, with another 600 soon to switch to green H.2 Previously Air Liquide, a partner in the Paris taxi project, completed construction of the world’s largest Proton Exchange Membrane electrolyzer, powered entirely by renewables to generate green hydrogen. Sited in Canada, its capacity has doubled to produce up to 8.2 tonnes per day from the 20MW facility. Scaling up is essential. Only with high volumes – of electrolysis, vehicles, and other hydrogen applications – will it be possible to achieve reasonably competitive price levels. Only when scale is achieved can hydrogen become a new energy vector to transfer surplus renewable power to importing countries in the form of liquid hydrogen or ammonia, replacing – in the second part of decade – what LNG has done for the past 40 years. Only when hydrogen alternatives are affordable will take-up be sufficient to reach Net Zero. An article by These goals require us to act on our ambitions through PIERRE-ÉTIENNE FRANC development of projects on a realistic and replicable scale, each backed by a sustainable business model. By carefully CEO at FiveT Hydrogen planning and executing the next major projects, we will show and Hy24 tangible results before 2030 and sooner, creating the impetus to carry on scaling up. 65
