Renewable natural gas produced by OPAL Fuels is utilized primarily within the heavy-duty commercial transportation sector across North America. It serves as a clean, low-carbon drop-in replacement for traditional diesel fuel, powering large commercial vehicle fleets such as municipal transit buses, refuse and waste collection trucks, and long-haul freight transport carriers. The fuel is dispensed through a specialized network of compressed natural gas and renewable natural gas fueling stations owned, operated, or serviced by the company. By adopting this fuel, commercial fleet operators can drastically reduce their greenhouse gas emissions while meeting strict corporate sustainability goals and complying with regional low-carbon fuel standards.
