The 37th America's Cup in Barcelona 2024 is witnessing a significant technological advancement with the introduction of hydrogen as a fuel source for support boats. Emirates Team New Zealand has developed 'Chase Zero', a hydrogen-powered chase boat equipped with foils, promoting sustainable energy use in the nautical sector. The vessel, powered by hydrogen fuel cells generating 440 kW of power, offers impressive speed capabilities and a range of 93 to 111 miles. Toyota, ETNZ's longstanding partner, played a crucial role in providing essential fuel cells. The construction of 'Chase Zero' began in 2021, incorporating innovative technology for enhanced performance. The collaboration between multiple companies, such as Air Products and ACCIONA Energía, underscores the joint effort in promoting green hydrogen use at the America's Cup. The integration of hydrogen and lithium battery propulsion aims to reduce emissions and carbon footprint while enhancing speed and efficiency in the competition.
