The aviation industry is facing a critical juncture in its history with the urgent need to achieve net zero emissions by 2050. Aviation currently contributes around 2.5% of global CO2 emissions, which could rise to 22% by 2050 as other sectors decarbonize. To combat this, hydrogen fuel cells combined with electric engine technology are being heralded as the most viable and scalable solution to drastically cut carbon emissions while reducing operational costs. Efforts in 2025 will focus on leveraging hydrogen fuel in aviation, with four key areas identified for success: hydrogen infrastructure, regulation, policy, and investment. Robust infrastructure is vital to scale up hydrogen production and enable safe storage and refueling at airports. Initiatives are underway to integrate hydrogen infrastructure with existing energy systems and grid operations. Regulation is another critical aspect, with standards groups and regulators actively addressing gaps in the regulatory landscape for hydrogen as aviation fuel. The FAA's Hydrogen-Fueled Aircraft Safety and Certification Roadmap outlines strategies for introducing hydrogen-powered aircraft safely. Policy and investment are also key pillars for success. The industry is witnessing a shift towards hydrogen, with many airports preparing for the transition. Collaboration among regulators and countries will facilitate international trade and boost the industry's global reach. Overall, the future of hydrogen in aviation looks promising, with concerted efforts across infrastructure, regulation, policy, and investment paving the way for a more sustainable and efficient aviation sector.
