Following on from its webinar held on 8th April 2020, the California Fuel Cell Partnership (CaFCP) has shared some of them questions asked.
Titled, Update on Network Development Status in California, the webinar had a focus on station progression, projections, and future developments across California and other states.
Some of the questions asked and answered in the webinar included:
Fuelling: What is H70 and H35?
Hydrogen is dispensed as a pressurised gas, and the numbers refer to the pressure at which hydrogen is dispensed. The H70 designation indicates a dispensing pressure of 70 Megapascals (MPa) or approximately 10,000 psi. H35 indicates a dispensing pressure of 35 MPa or approximately 5,000 psi.
Locations: How can I find out where and when the new stations are to open?
The H2 Stations List provides information about the status of stations in development and can be found of CaFCP’s resource page. The document is updated monthly and relies on information provided by station developers.
Will stations built for the heavy-duty trucks be restricted only to trucks or will passenger vehicles be allowed to full up at those stations?
In general, being able to provide hydrogen fuel to light-, medium- and heavy-duty vehicles at a single location depends on several factors, including the footprint of the station and site, station developer strategy and business models, along with other factors.
Today’s conventional fuelling locations rarely co-locate light- and heavy-duty fuelling, with the exception being interstate travel plazas. Nikola Motor, however, has indicated they will offer fuel to various categories.
What is the expected lifetime of a fuel cell stack for light duty/passenger cars, and heavy-duty buses and trucks?
Generally, automakers of cars, buses and trucks aim for a fuel cell stack lifetime that matches the longevity of a typical vehicle engine in that category.
For example, many automakers of passenger cars aim for a fuel cell stack lifespan of at least 5,000 hours or approximately 150,000-200,000 miles. In the heavy-duty category, bus fuel cell stacks have reached lifetimes of 20,000 hours and more, with a goal of 30,000 hours by 2030.
2020 seemed to be shaping up as a pivotal year for hydrogen station development. Can you estimate the impact from COVID-19 on any reduction efforts?
The COVID-19 pandemic has slowed, in some cases, but not stopped the rollout of hydrogen stations. Hydrogen stations that were open for retail commerce before the shelter-in-place are still open and considered essential businesses, much like gas stations and charging stations.
Some activities related to station network expansion, including funding and planning, are continuing. The CEC released a grant funding opportunity for light-duty stations in late December and the deadline to submit is late May. It is expected to fund 40 to 50 stations, pushing California past the 100-station milestone and toward the state goal of 200 hydrogen stations by 2025.
