Hydrogen will be the 'only viable economic choice for zero-emission long-haul trucking': US freight body
But battery electric vehicles will be a better option for shorter journeys, says new report from North American Council for Freight Efficiency
Both battery electric and hydrogen trucks for zero-emission road freight in North America, with the latter required for long distances, according to a new report by the North American Council for Freight Efficiency (NACFE).
Hydrogen: hype, hope and the hard truths around its role in the energy transition
“Battery electric vehicles will inherently be the most economical and efficient choice for shorter distance zero-emission duty cycles, and hydrogen will be the only viable economic choice for long-haul zero-emission duty cycles.”
“Duty cycle” is an industry phrase describing how much a vehicle is used, including the frequency and length of journeys and the weight of the payloads.
“There really are no viable alternatives to hydrogen for hauling freight 600+ miles per day with zero emissions,” the report explains. “While it is technically viable for a battery electric truck to go 800+ miles in a day with en-route charging and carrying equivalent freight weight to a diesel, the situations where this is feasible are limited.”
However, as the numbers above suggest, there is some overlap between the two drivetrains for mid-range and mid-weight journeys. “Ultimately, fleets in the market will make decision on which technology succeeds for which duty cycles.”
The study does, however, point out that “the cost of hydrogen production, transportation storage and dispensing will not be cost competitive with diesel without significant assistance from tax credits and other subsidy mechanisms”.
“Significant cost reduction across all cost elements is needed” for fuel-cell trucks to be cost effective, it adds.
“Supply chain companies from shippers, to carriers, to fuel suppliers and others along with government assistance, must share in higher costs for the benefits of zero emissions.”
It adds that the future acceleration of hydrogen fuel-cell trucks “is likely not about the vehicles or the fueling, but more about the creation and distribution of the hydrogen itself” — despite pointing out that they will be more expensive to buy and run than battery electric equivalents.
Industry agreement is also needed on whether hydrogen trucks and infrastructure will be based on gaseous or liquid hydrogen, the report says.
The report also says that internal combustion engines burning hydrogen and bio-based natural gas and “renewable diesel” (produced from green hydrogen and biofeedstocks) “will be required to support the transition in the next two decades to help make progress toward zero-emission goals, while in parallel ramping up the hydrogen and battery electric infrastructure and manufacturing base”.
NACFE describes itself as “an unbiased and fuel-agnostic organization… [that] “works to drive the development and adoption of efficiency enhancing, environmentally beneficial, and cost-effective technologies, services and methodologies in the North American freight industry”.
