Hydrogen-powered planes hold the potential to address aviation's emissions problem, offering a zero-emission alternative to fossil fuels.
Hydrogen's high energy density and emission-free properties make it a promising fuel for aviation, as it is 3-4 times lighter than jet fuel by energy basis.
The aviation industry aims for net zero emissions by 2050 due to aircraft being responsible for 2.5% of global CO2 emissions, and hydrogen is seen as a key solution.
Electric planes face range limitations due to battery weight, while hydrogen's energy density could enable longer flights without emissions.
Airbus, ZeroAvia, and Universal Hydrogen are notable players exploring hydrogen aviation technology, with successful test flights on small aircraft.
Challenges include hydrogen storage, fuel cell durability, and regulatory approval, potentially limiting hydrogen's application to smaller and medium-sized aircraft initially.
Hydrogen's cost advantage over fossil fuels and advancements in renewable energy production contribute to its potential economic viability.
Despite hurdles, experts believe hydrogen remains a promising option for decarbonizing aviation in the long run.
However, challenges in technology, infrastructure, and regulation must be overcome.
