Abstract
In 2008, The Boeing Fuel Cell Demonstrator achieved straight - level flight on a manned A hydrogen powered aircraft is an airplane that uses hydrogen as a power source In aircraft hydrogen can either be based in some kind of jet engine, or other kind of internal combustion engine, or can be used to power a fuel cell to generate electricity to power a propeller. Being an alternative to jet fuel, hydrogen has a higher energy density per unit mass but a lower energy density per unit volume, and containing the hydrogen at high pressure would require a heavy container. In aircraft heavy containers are not an option, and therefore regular carbon fiber tanks are often used, which can only sustain a pressure of 350 bar. When compared to steel hydrogen containers (used in cars and ships), this is 500 to 700 bar. This decreases the amount of energy that can be spent on the propulsion by half. Alternatively, as with some rockets, cryogenic liquid hydrogen could be employed. If hydrogen were available in quantity from renewable energy sources, its use in aircraft would produce fewer greenhouse gases (water vapor and a small amount of nitrogen) than current aircraft. Currently, very little hydrogen is produced using renewable energy sources, and there are several serious obstacles to the use of hydrogen in aircraft and other vehicles. will probably not enter service until closer to 2040.
