Computer chip giants Intel regularly utilize three trucks fitted with these hydrogen fuel injected (HFI) systems. They are used for transporting trade-show materials across North America between shows such as the aforementioned CES and the IDF (Intel developer Forum). The journeys span huge distances, the likes of Florida to Canada. A normal non-HFI truck would average somewhere between 5 and 6 miles per gallon. A truck fitted with an HFI system typically averages around 6.3 mpg. One HFI truck journey across California averaged 7.2 mpg offering a much improved mpg rate and a significant reduction in terms of its carbon footprint.
