Efficiency decreases for small internal combustion engines. A 67 ml 4-stroke engine converted to hydrogen and tested with a dynamometer at the best operating point (3000 rpm, 14 NLM (normal liters per minute), 2.5 times stoichiometric air/fuel ratio) achieved 520 W and 21% efficiency. In order to measure the vehicular efficiency an also ...
Hydrogen internal combustion engine cars are different from hydrogen fuel cell cars. The hydrogen internal combustion car is a slightly modified version of the traditional gasoline internal combustion engine car. These hydrogen engines burn fuel in the same manner that gasoline engines do; the main difference is the exhaust product.

The California Air Resources Board has projected that more than 10% of new cars sold in 2035 will be fuel cell vehicles, growing to more than 20% annually by 2045.
A major component of California's hydrogen hub ... of 5.5 million gas-powered cars, according to the DOE. Hydrogen can be produced from a variety of sources including natural gas, nuclear power ...
The journey took 19 hours 40 minutes with hydrogen consumption of 0.9 kg per 100 km (16.1 kg of hydrogen consumed). [ 102 ] The second generation Mirai was awarded in May 2021 by the Hispanic Motor Press for 'Car Technology of the Year', noting the commitments towards zero emissions and Toyota Safety Sense.
In September 2006, California Senate Bill 1505 required 33% of hydrogen to come from renewable energy sources, [3] [4] and other initiatives followed. [5] As of 2007, 25 stations were in operation. [6] Some of these hydrogen fueling stations completed the terms of their government-funded research demonstration project and were decommissioned. [7]
