Most conversations about decarbonizing heavy transport are stuck in a childish binary: batteries good, hydrogen bad. Luijten gives a concrete operational reason fleets start with battery-electric and then add hydrogen as the second pillar: predictability. They got to a couple of dozen battery-electric trucks and then hit a wall. Build a station where trucks actually return every day, lock in baseline demand, then connect those islands into corridors. Electrolyzers can act as grid balancers, soak up excess generation, stabilize the system, and convert electricity into something storable and movable.
