They favor CNG instead of hydrogen fuel cells, which they say are still unreliable. After developing three generations of hydrogen-powered cars, Fiat says that it is still too difficult for states to implement a hydrogen infrastructure that can […]

Natural gas vehicles, especially heavy duty trucks and buses, are gaining momentum in the marketplace. Extraction of natural gas and tightening emissions regulations are making these vehicles both more attractive […]

One way is to improve fuel economy, including engine design and partial or full electrification. These methods are helpful, but with the increasing availability of natural gas, perhaps a change in fuel is worth looking into. Since compressed natural gas […]

Natural gas is being used in power plants, which are much cleaner than coal-fired plants, as well as in vehicles. Increasing the number of vehicles that run on compressed natural gas [CNG] might seem like a […]

Yet methane, even if it's a sibling of petrol, got its way through the alternative fuels industry, and it is more widely used nowadays, as fuel prices oscillate between skyscrapers and small houses. Methane is also one of the cleanest burning fuels, and that makes it viable for a while. Methane reservoirs still exist all around the world, and there's plenty of it to help make a clean transition to hydrogen.
