Aviation is undergoing a transformation. If earlier it was a question of propeller-driven or jet-propelled aircraft, now more and more often we are talking about aircraft powered by electricity. This has found more application in drones, including industrial ones. Gradually, several large companies approached the development of air taxi. It is assumed that in the future it can replace the traditional.
However, the implementation of such projects is complicated by the fact that the batteries for powering the power plant have significant weight. HyPoint developers are confident that the future is not for lithium-ion batteries, but for hydrogen cells. The latter have a lot of advantages – a higher energy density and a short refueling time. Startups have found a way to significantly improve the parameters of existing hydrogen elements.
Their system uses an air cooling system, which made it lighter and eliminated additional elements. In addition, hydrogen elements are placed in an air channel blown by compressed air. Also, air with a high oxygen content is supplied to the system. All this led to the fact that the energy density increased by three, reaching a value of 2000 W / kg.
Startups assembled a prototype installation, which worked in the laboratory for about 20,000 hours. A prototype with a capacity of 15-20 kW may appear already this year, and a commercial even more powerful installation will be presented in 2022. The startup has already entered into agreements with several large companies from different countries operating on the VTOL field.
