British engine manufacturer Rolls-Royce is currently developing turbogenerator technology in order to extend the range of hybrid-electric aircraft. 

According to the company, turbogenerator technology will be scaled to serve a power range between 500 kW and 1200 kW. This means that more passengers will be able to travel further on low to net zero emissions aircraft in the future, the company said. 

The new turbogenerators “will recharge batteries after take-off or power propellers directly, enabling aircraft to switch between power sources in flight”.  

According to Rolls-Royce, the new system will also be used with sustainable aviation fuels (SAF) and hydrogen combustion. 

“As part of our strategy, we are looking at offering the complete sustainable solution for our customers. This means extending routes that electric flight can support through our turbogenerator technology,” Rob Watson, president of Rolls Royce Electrical, said. 

Rolls-Royce says that it is committed to ensuring its new products will be compatible with net zero by 2030 and all its products will be compatible with net zero by 2050.
