The alternative power choice that has made the deepest inroads into trucking and will remain a key player for years to come is natural gas. Whether in its more popular compressed (CNG) or liquefied (LNG) form, natural gas is proving to have staying power, even in the face of reasonably low and fairly steady diesel fuel prices.
Of course, natural gas did not roll onto the scene aimed at being a cheaper-than-diesel fuel choice. Rather, it was adopted as a practical alternative for all types of truck fleets that need to cut tailpipe emissions of greenhouse gases, either to comply with environmental regulations or to meet corporate and/or customer sustainability requirements.
