British firm to unveil technology for zero-carbon emission flights at Cop26
A British company being launched at the Cop26 summit on Friday will unveil technology it claims could enable zero-carbon emission flights running on liquid ammonia by 2030.
It aims to build lightweight reactors to “crack” the chemical to produce hydrogen to burn as fuel, a design it says could allow existing planes to be modified to store liquid ammonia rather than paraffin.
Hydrogen is currently seen as the only possible “clean” fuel for future long-haul aviation, but the difficulty of safely storing it in fuel tanks, either as a gas or highly cooled liquid, means aerospace manufacturers have argued that vastly different planes would be needed.
Small reactors could be retrofitted into passenger planes to allow the hydrogen to be obtained from
