Faced with increasing pressure to reduce emissions in the aviation sector, a study published in the Brazilian Journal of Civil Aviation and Aeronautical Sciences points to hydrogen as one of the main technological bets to transform the aviation energy matrix. In a scenario of accelerated recovery of air transport in the post-pandemic period, and with projections of significant expansion of the global fleet, the search for sustainable fuels has become imperative to mitigate the environmental impact of one of the most carbon-intensive sectors.
Technical challenges and innovation in engines redefine the future of aeronautical propulsion
The analysis highlights relevant advances in the development of hydrogen engines that explore adaptations of conventional turbofans to operate with this energy vector. However, large-scale adoption still faces significant technological barriers, especially related to the storage of hydrogen in liquid state, which requires cryogenic tanks, new aircraft architectures and more complex distribution systems.
In addition, hydrogen presents logistical and economic challenges that impact the entire aviation value chain. Nevertheless, the study highlights that the combination of technological innovation, global commitments to carbon neutrality by 2050, and industry investments can accelerate the transition. In this context, hydrogen not only positions itself as a viable alternative to fossil fuels, but also as a catalyst for a structural reconfiguration of aeronautical engineering in the coming decades.
