Hyzon's first liquid hydrogen-fuelled truck travels 870km without refuelling in 16-hour test run
Liquefied H2 is ‘economical’ option for heavy-duty vehicles due to higher fuel density, says zero-emission truck maker’s CEO — despite risk of boil-off
Hyzon has completed its first commercial trial of a liquid hydrogen fuel cell electric vehicle, making eight deliveries in Texas over more than 540 miles (870km) without refuelling in a single 16-hour run.

“With increased range and no added weight in comparison to our gaseous hydrogen trucks, we believe this liquid hydrogen demo run has demonstrated potential viability for the future of liquid hydrogen in commercial trucking,” said Hyzon’s CEO Parker Meeks.
“The results we captured in the strenuous demo through Central Texas’s diverse terrain and summer heat make us optimistic that, once commercialized, our liquid hydrogen vehicle powered by our proprietary 200kW fuel cell system should be able to provide long distance range between 650 and 800 miles, on par with many diesel truck range requirements,” he added.
Cryogenic storage tanks were provided by Chart Industries, which effectively maintain extremely cold temperatures passively with a vacuum seal between two walls.
“Simply put, we see liquid hydrogen as the economical approach to long range zero emission trucking,” Meeks added.
Hyzon is currently in the midst of being investigated by the US Securities and Exchange Commission over allegations of fake customers and exaggerated orders in its financial statements.
And an internal investigation admitted in March this year that more than half of its 87 vehicles delivered in 2021 were not operable or required post-delivery repairs, prompting a revision of recognised revenue in its reports.
While at the time, stock exchange Nasdaq threatened to delist the company due to delays in filing the new reports and shares trading below $1 for ten consecutive days, Hyzon has regained compliance on both these points.
