Abstract(s)
O uso do hidrogénio na aeronáutica é promissor devido aos benefícios ambientais, como
emissões zero de carbono, resultantes da sua combustão. A utilização de hidrogénio requer
avanços em tecnologia e normas, incluindo armazenamento seguro, adaptação de aeronaves e
infraestrutura, bem como a certificação dos sistemas e organizações que vão utilizar H2.
A transição da propulsão convencional de aeronaves para a propulsão a hidrogénio
representa uma mudança significativa para uma fonte de energia mais limpa e sustentável. Essa
transição implica a substituição dos combustíveis tradicionais por hidrogénio, atendendo aos
benefícios ambientais. No entanto, essa mudança requer avanços tecnológicos, como o
desenvolvimento de motores e sistemas adaptados ao hidrogénio, além de normas rigorosas para
garantir a segurança, o armazenamento eficiente e a certificação de aeronaves movidas a
hidrogénio.
Embora ainda em fase de desenvolvimento, a propulsão a hidrogénio representa uma
abordagem promissora para reduzir o impacto ambiental da aviação, com isto concluímos que vai
ser necessário superar desafios tecnológicos, alcançar viabilidade económica e resolver questões
logísticas e regulatórias. O progresso dependerá da colaboração entre setores, governos, empresas
e organizações de pesquisa.
The use of hydrogen in aeronautics is promising due to environmental benefits, such as zero carbon emissions resulting from its combustion. The use of hydrogen requires the improvement of technology and standards, including storage safety, aircraft structures adaptation, infrastructure, and certification of the systems and organizations using H2. The transition from conventional aircraft propulsion to hydrogen propulsion represents a significant shift toward a cleaner and more sustainable energy source. This transition involves replacing traditional fuels with hydrogen, regarding environmental benefits. However, this change requires technological progress, such as the development of engines and systems adapted to hydrogen, along with rigorous standards to ensure safety, efficient storage, and certification of hydrogen-powered aircraft. Although still in the development phase, hydrogen propulsion represents a promising approach to reduce the environmental impact in aviation. It is concluded that overcoming technological challenges, achieving economic viability, and resolving logistical and regulatory issues will be necessary. Progress will depend on collaboration among sectors, governments, businesses, and research organizations.
