Hydrogen-burning internal combustion engines offer great promise in the fight against climate change because they are powerful without emitting any earth-warming carbon.
Hydrogen-burning internal combustion engines offer great promise in the fight against climate change because they are powerful without emitting any earth-warming carbon.
They can power heavy-duty trucks and buses and are suited for off-road and agricultural equipment and backup power generators, providing cleaner alternatives to diesel engines.
Yet they are not entirely clean. They emit nitrogen oxides during the high-temperature combustion process. Nitrogen oxides react with other compounds in the atmosphere to form harmful ozone and fine particulate matter, which aggravate our lungs and lead to long-term health problems.
