The North County Transit District is transitioning from buses powered by natural gas to hydrogen to meet state environmental mandates. But the closest hydrogen fuel source is located in Ontario and Is 10x more expensive than natural gas. To get around this higher cost and distance, NCTD is building its own hydrogen fueling station so that they can truck in cheaper, liquified hydrogen and convert it to gas on site. How does the liquified hydrogen get transported to NCTD for conversion into fuel?
