Hexagon Agility's natural gas fuel system and related hardware were some of the biggest stars of this year's ACT Expo in Anaheim, California.

Why? Because fleets who are aiming to lower their greenhouse gas (GHG) emissions want a reliable and proven replacement for traditional diesel.

But it's not only trucking fleets that recognize the immediate benefits of natural gas as a fuel, whether it be renewable natural gas (RNG) or compressed natural gas (CNG).
Transit bus manufacturer GILLIG recently placed an order with Hexagon for CNG fuel systems that'll power 476 new buses for Dallas, Texas. According to city officials, over 30 million passengers utilize the Dallas Area Rapid Transit (DART) annually, more than enough justification to invest in safer, cleaner, and more efficient public transport.

The city is currently gearing up to host the FIFA World Cup in spring of 2026, and it promises the new CNG-powered bus fleet will be up and running by then. In fact, the first fuel system deliveries will get underway this business quarter.
"We’re proud to continue our collaboration with GILLIG in delivering industry-leading CNG fuel systems for transit fleets," said Ian MacDonald, head of fuel systems at Hexagon Agility. "As cities like Dallas invest in upgrading their transit systems, CNG stands out as a proven long-term solution because it cuts emissions, lowers fuel and maintenance costs, and improves fleet reliability."
Alternatives to traditional diesel in public transit buses is nothing new. Some cities have opted for pure battery-electric buses while others, mostly overseas, have been experimenting with hydrogen-powered buses, though the results have been mixed, at best.
