Rolls-Royce has tested its hydrogen-powered jet engine

The British manufacturer claims to be the world’s first in nature. He tested a hydrogen-powered jet engine on the ground. Although this news gives hope to really see hydrogen as the zero fuel of the future, doubts remain.

Rolls-Royce offers hope

In recent years, the famous company Rolls-Royce has distinguished itself with many of its projects. However, this is about it launch of autonomous and connected cargo shipsa flying taxi concept or will of breaking the world speed record in an electric plane. Now Rolls-Royce is focusing on hydrogen, touted as a clean energy source that is highly capable help with energy transition in many sectors.

In an article published by Guardian on November 28, 2022, the British manufacturer explains that it tested an underground mill running on 100% hydrogen.. These tests, which would be the first according to Rolls-Royce, took place within the brand’s facilities in Boscombe Down (Wiltshire). In the heart of the test, we find the AE 2100 turboprop. Usually, the latter flies medium-sized aircraft.

According to Rolls-Royce, this test is very important for the supporters of hydrogen, that is to say those who believe that this source of energy can include zero fuel aviation of the future. However, you should know that the method of hydrogen production is very important. In fact, this could be very disappointed in fossil fuels. However, Rolls-Royce has shown that its approach is entirely based on renewable energy from tidal turbines.

Doubts are still there

Note, however, that hydrogen emits just water vapor – however contributing to the greenhouse effect. However, this same hydrogen represents a very strong candidate for the decarbonization of the commercial aviation sector. The latter continues to expand, as well as increasing its ecological footprint. However, the will of making the arrival of hydrogen a reality in the future the aviation market raises questions, despite encouraging attempts from Rolls-Royce. Of course, hydrogen will not be used in all cases.

More than that, hydrogen storage in aircraft it will be quite difficult, since it will be a question of combining temperature (freezing) and pressure (high). Therefore, manufacturers will have to rethink the interior of aircraft and tanks, especially since the amount of fuel will be greater than that of current kerosene. According to Michael Liebreich, founder of Bloomberg New Energy Finance, aircraft such as the Boeing 747 it will require a million liters of hydrogen to cover the distance he could cover with “only” 250,000 liters of kerosene.
