The document proposes a strategic commercialization path for fuel cells and hydrogen (H2) that avoids the need for immediate, massive bulk-supply infrastructure. The strategy relies on the development of "Hypercars"—ultralight, high-efficiency vehicles—and the integration of fuel-cell deployment between buildings and vehicles. By first establishing fuel cells in buildings for co- or trigeneration and using decentralized "hydrogen appliances" for production, the market can build the volume necessary to reduce fuel-cell costs to levels competitive for vehicles. Ultimately, the strategy envisions a transition from decentralized production to bulk supply, including wellhead reforming of natural gas with carbon sequestration and the conversion of hydroelectric dams into "Hydro-Gen" plants.
