The Problems with Hydrogen-Powered Aircraft
“What are the barriers to the deployment of hydrogen aircraft?”
Aircraft powered by hydrogen fuels could have the potential to be a massive boon for deep decarbonization in aviation. Being able to be powered by a carbon-free energy source that is also mass-dense gives it an immense advantage over battery electric aircraft. Although Hydrogen is one of the most dense substances by mass, it is one of the least dense by volume. This means that it will take up a significant share of an aircraft’s space, hampering flying opportunities. And just like in hydrogen-powered cars, directly burning hydrogen can be incredibly dangerous. These are The Problems with Hydrogen-Powered Aircraft.
