Diesel has dominated heavy-duty trucking for a reason.
It is energy-dense, widely available, familiar to fleets, and supported by a massive fueling and service network. But it is not the only option.
Natural gas semi trucks have been used in commercial fleets for years, especially in refuse, regional haul, port drayage, delivery, and return-to-base operations. They run on either compressed natural gas (CNG), liquefied natural gas (LNG), or renewable natural gas (RNG), offering a lower-emissions alternative to diesel for certain heavy-duty applications.
They are not perfect. They are not a drop-in answer for every fleet. But they are also not experimental.
Natural gas trucks are one of the more mature alternative-fuel options available for heavy-duty commercial transportation today.
Natural gas semi trucks can reduce emissions and fuel-cost volatility in the right application, especially for fleets with predictable routes and access to CNG, LNG, or RNG fueling. The biggest limitations are fueling infrastructure, onboard fuel storage, upfront cost, range planning, and application fit.
