White-Space Opportunities for Natural Gas-Powered School Buses and Alternative-Fuel Fleet Transportation

In February 2026, the U.S. Environmental Protection Agency (EPA) identified a significant opportunity in natural-gas-powered school buses and alternative-fuel fleet transportation by considering a greater share of the approximately USD 2 billion remaining under the Clean School Bus Program for buses powered by natural gas, biofuels, or hydrogen. 

The largest investment opportunity is therefore in school-bus replacement and procurement, where the Bipartisan Infrastructure Law established a USD 5 billion five-year Clean School Bus Program, of which EPA had already allocated about USD 3 billion for 8,500 buses, with roughly 90% of those buses being battery electric. The remaining USD 2 billion could provide greater opportunities for compressed natural gas (CNG) and liquefied natural gas (LNG) buses, while other investment areas include natural-gas powertrains, CNG/LNG fueling infrastructure, vehicle conversion and fleet maintenance.

The potential funding shift is expected to create opportunities for companies across the natural-gas school-bus and fueling value chain, with Cummins positioned to benefit through the supply of CNG/LNG engines for medium- and heavy-duty buses, while Blue Bird Corporation and Thomas Built Buses can benefit through the manufacturing and deployment of alternative-fuel school-bus platforms. 

Hexagon Agility can benefit from increased demand for CNG/LNG onboard fuel-storage and delivery systems, while Clean Energy Fuels can benefit from additional demand for natural-gas and renewable-natural-gas fueling infrastructure and fleet fueling services. Love's Travel Stops, through its Clean Energy Fuels-related natural-gas fueling network, can also benefit as school and commercial fleets require additional CNG/RNG fueling access.

Volatility in natural gas and LNG prices is increasing fuel-cost uncertainty and reducing the economic attractiveness of natural gas engines

Volatility in prices of natural gas and LNG is causing uncertainties with respect to the operating economics of natural gas engines, especially for power producers, industries, and commercial fleets which compete with diesel, electricity, or any other fuel technologies. As the cost of fuel is a regular cost element within the total cost of operation, any sudden changes in natural gas prices may cause an erosion in the economic benefit that may favor changing from diesel to natural gas engines. It is especially true with respect to LNG-based economies due to the volatility in spot prices and supply chain interruptions.

The increasing volatility of gas markets is creating greater uncertainties regarding the cost of fuel for natural gas engines and the economics of gas-fired power generation. In September 2026, according to Reuters, the prices of benchmark natural gas in Europe reached approximately €75 (USD 86.96)/MWh, rising more than twice as high as one year ago and reaching the highest point since late 2022. Reuters also stated that gas reserves in Europe were only at 66%, which is 12 percentage points lower than one year before, while exports of LNG from the Gulf declined by more than 85% in March through August 2026 relative to the same period one year before. Despite an increase in production of LNG in regions outside the Gulf by 18%, or approximately 27 billion cubic meters, during the year to June 2026, it compensated only around 75% of the lost supply from the Middle East.
