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.

"We must wage the battle of innovation and industrialization at the same time," he told a group of entrepreneurs, adding: "We need a country that produces more."
