No one expects to burn hydrogen in ICE, all future hydrogen cars will use fuel cell. Under current energy and power rules fuel cell should produce constant 300 kW and battery buffer will take care for peak power and KERS. The major problem will obviously be weight and space (aero). A hydrogen fuel tank alone with 5 kg (710 MJ ~7 LeMans laps) of fuel capacity currently weights 90 kg.
