Clean fuel supplier Ryze has entered into a partnership with ZeroAvia to supply hydrogen for engine and flight testing at Cotswold Airport in Cirencester, UK. This collaboration highlights the increasing infrastructure developments in the hydrogen sector, particularly in aviation. Sergey Kiselev, Chief Business Officer at ZeroAvia, emphasized the importance of cost-effective clean hydrogen in achieving their goals of zero-emission flight. The partnership with Ryze is seen as a crucial step towards advancing testing and certification processes. Alex Webster, Head of Business Development at Ryze, expressed the significance of this partnership in driving progress towards a hydrogen economy, both locally and globally. The consistent delivery of hydrogen to ZeroAvia's testing site will aid in the advancement of the company's flight test program to meet certification requirements for their ZA600 engine, intended to power a 20-seat aircraft. Ryze's tube trailer fleet, known as the largest in the UK by capacity, will play a vital role in providing the necessary flexibility to support ZeroAvia as they scale up their research and testing activities on the hydrogen-electric powertrain.
