Electric vehicles have the advantage of being able to depend on an existing power generation and distribution system—the electrical grid.They produced over 900,000 new vehicles in 2021 and have installed a global fast charging network of 35,000 superchargers to support them.The cost of developing hydrogen refueling stations and scaling up hydrogen production will also be extensive.Investment in technologies to bring public transport systems to cities in developed nations at the turn of the 20th century, to fight wars, and to power modern economies all emerged at a time when governments took responsibility for the need to invest, plan and control production and consumption in the national interest.The proactive planning and construction of such systems has always been underpinned by the idea that national interests are at stake."
