Stakeholders in the zero emission field are advocating for green hydrogen to replace fossil fuels, with pathways like electrolysis, biomass-to-hydrogen, and plastic waste-to-hydrogen being explored. Research on converting brown seaweed into green hydrogen shows its potential as an economical and carbon-neutral source. Studies on seaweed growth rates and alkaline thermal treatments are improving hydrogen production efficiency. Water electrolysis for green hydrogen production is gaining traction, with industrial use cases like green ammonia supporting ventures shielded from global fuel market disruptions. Battery-electric vehicles are expected to dominate the road freight sector, while hydrogen fuel cell transport plays a complementary role in specific applications like long transport routes or regions with insufficient charging infrastructure. Ventures like Ballard, Bosch RexRoth, Clean Energy Fuels Corp., and Hyroad Energy are making strides in fuel cell buses, advanced pumping systems, hydrogen fueling stations, and hydrogen refueling stations for commercial truck fleets.
