According to a new report by Polaris Market Research, the global hydrogen aircraft market was valued at USD 679.60 million in 2025 and is projected to reach USD 6,372.35 million by 2034, expanding at a CAGR of 28.23% over the forecast period. Growth is underpinned by rising emission regulations, increasing jet fuel prices, growing air travel demand, and expanding hydrogen infrastructure.

What Is Driving Hydrogen Aircraft Market Growth?

Demand is climbing as strict global emission regulations converge with volatile, rising jet fuel prices. Jet fuel prices rose from USD 1 per gallon to USD 4 per gallon between April 2020 and April 2022, pushing airlines toward hydrogen as a more price-stable alternative fuel. Under the EU ETS, airlines operating in Europe must monitor, report, and verify their emissions and surrender corresponding allowances, making hydrogen aircraft's zero-emission profile a compelling compliance path. Polaris analysts note that IATA reported total air traffic, measured in revenue passenger kilometers, rose 36.9% in 2023 compared to 2022, positioning hydrogen aircraft for sustained growth through 2034, with the commercial segment emerging as the leading application and military & defense posting the fastest incremental gains.
