Lieutenant Isaac Wade, a marine engineer officer, is championing the integration of hydrogen technology for ship propulsion in the New Zealand Defence Force (NZDF) and Royal New Zealand Navy (RNZN). Wade's publication on Applications of Hydrogen Technology to the NZDF and RNZN highlights the potential uses of hydrogen technology in Defence, emphasizing its sustainability and the possibility of enhancing New Zealand's fuel independence. In collaboration with Hyundai NZ, a portable power generation system with Electrical Vehicle charging capability, powered by two fuel cells producing 160 kilowatts of power, was demonstrated. This system is deemed suitable for remote applications and could replace traditional diesel generators. Wade envisions the system's utility in Humanitarian and Disaster Relief scenarios, proposing its integration with renewable energy sources like wind and solar to produce hydrogen. He also suggests the Navy's adoption of hydrogen technology in various forms, such as dual-fuel systems, pure hydrogen fuel cell ships, and potential replacements for existing vessels. LT Wade's advocacy stems from his belief in the transformative potential of hydrogen technology, noting New Zealand's historical leadership in this field and the promising opportunities it presents for the future.
