This year’s edition of the Advanced Clean Transportation Expo featured a more balanced range of driveline technologies, from battery and fuel cell electric at one end of the scale to propane, natural gas, and hydrogen combustion at the other. However, decarbonising the internal combustion engine is not as simple as replacing diesel with a different fuel; the different combustion characteristics of natural gas and hydrogen require alterations be made to the engine so that it works optimally with the new fuel type. One company which has thought long and hard about how to make these necessary tweaks is Eaton Corp. Scott Adams, who is senior vice president of technology and global products for Eaton’s Mobility Group, guided Truck & Bus Builder through the company’s portfolio, showing cutting-edge prototypes as well as its established range of power management technologies.

After attending the Advanced Clean Transportation Expo in the past two years, we were of the view that the USA may catch up with Europe to become the world’s largest electric vehicle market after China. Following the 2025 edition of the ACT Expo – held between 28 April and 1 May in Anaheim, California – I now have serious doubts about how long it will take for America to overtake Europe, if it happens at all. There was a palpable shift away from electric vehicles in favour of alternatives such as natural gas, propane, and hybrid vehicles. Once the stars of the show, these options faded into the background when California’s zero emission vehicle mandate passed into law. Now, the progressive state has repealed the mandate, after the Environmental Protection Agency in January 2025 withdrew the waiver which allowed California to enforce zero emission quotas on fleets; consequently, the low-emission alternatives to diesel and electric are enjoying a revival of interest from many kinds of customer.
