France wants to be a leader in green hydrogen by 2030 and build new, smaller nuclear reactors as part of a 30 billion euro ($35 billion) investment plan to foster industrial champions and innovation, President Emmanuel Macron said on Tuesday.

Speaking six months before the presidential election, Macron said his long-term road map, dubbed "France 2030," would ensure the country massively decarbonizes its industry and brings industrial production in key areas closer to home.
