Commercial aviation is among the worst offenders when it comes to contributing to climate change through carbon dioxide emissions.
Naturally, the situation has changed since last year, when the
COVID-19 outbreak forced the cancellation of several commercial flights. But the issue still exists.
Hydrogen-powered aircraft are one of the solutions that have attracted a lot of interest from those working to achieve zero-carbon flying.
Commercial-scale hydrogen planes are moving closer to becoming a reality,
but the road there is not without its difficulties.
