zeroemission

The transport sector has been fighting for some years against a great enemy: its own CO₂ emissions. According to the European Environment Agency, this sector was the responsible of approximately 30% of emissions. And, of the total of these emissions, civil aviation represented 13.4%. The answer? The electrification in the case of land transportsomething that has been evolving at a good pace. In the case of commercial aviation, electricity was not opted for, but for hydrogen. The European Airbus was one of the companies that first jumped into the pool with a commitment to achieve the decarbonization goals with which the European Union seems to be very committed. Your proposal: hydrogen-powered zero-emission aircraft. That was the proposal in 2020 with a view to being achieved by 2035, and the prototypes of some companies they seemed hopeful. However, hydrogen has not done as well as many expected and the consequences are there: where it said “I say”, it says “Diego”, and now Airbus is not so clear that your zero-emission plane arrives on schedule. Airbus, its “green” plane and the turnaround of the industry Airbus’s proposal was extremely ambitious, since its hydrogen-powered aircraft would mark the greatest aeronautical revolution since the appearance of the jet engine. The idea was have hydrogen planes in the air by 2035for which presented three concepts: A turbofan for 200 passengers and 3,704 kilometers of range. A turbofan mixed wing model also for 200 passengers and 3,704 autonomy. A turboprop for 100 passengers and 1,852 kilometers of range. Its roadmap included the design of gas turbines with fuel injectors for hydrogen combustion to occur, but also models with completely electric systems powered by hydrogen fuel cells. They invested 1.7 billion dollars in the projectbut things began to go wrong both for Airbus and for the hydrogen industry as a vehicle “engine.” Germany is a good example of the difficulties of hydrogen as a fuel, at least for private vehicles. By the end of 2024, the main hydrogen station operator began to close facilities because there was no demand. The German Association of Energy and Water Industries itself revealed in a report that planned storage projects were significantly behind projected demand. For the private car, it seems that electrification has won the game, but in other types of vehicles such as trucks, buses or airplanes themselves, this fuel seemed to continue to be a valid option. At the beginning of this year, however, Reuters reported that Airbus was having problems obtaining green hydrogen. There is many types of hydrogen and their colors indicate how they have been obtained. What the sector needs is the so-called green hydrogen, which is produced thanks to renewable energies such as solar or wind. It is a process that needs a lot of investment and the company’s CEO doubted that enough could be produced to make commercial flights with hydrogen aircraft profitable. They did not shelve the project and, in fact, at the Airbus 2025 Summit reaffirmed their engagement, but soon after it seems they thought better of it. As we read in The Wall Street Journalthe company cut the budget allocated to green hydrogen airplane research by a quarter. Citing “technical challenges,” the company has reassigned staff other departments and the engineers responsible for the project appear to have gone back to the planning table. It is not a “never will arrive”, but it does seem to represent a slowdown in the plans that would imply that they would not arrive with that plane by 2035. In fact, in TWSJ they comment that Airbus defends that the money has not been thrown away and that delaying the project will allow the technology to be perfected. “Our destiny has not changed, but we need to adjust to reality to get there,” commented Bruno Fichefeux, head of future aeronautics programs. But it is not only Airbus that has taken a turn in its green policy. At the beginning of this year we saw that large oil companies began to stop or cut investment in their renewable energy programs to refocus on fossil fuel production. In this case it is not because the technology is green, but because there is an entity that has appeared on the board that requires large amounts of energy immediately: the data centers for AI training. Returning to hydrogen aircraft, although Airbus has put the brakes on its strategy, assuming a delay of five yearsthere are other companies that had a similar roadmap. For example, ZeroAviawhat’s next committed with hydrogen-powered flight and that has several models programmed in its roadmap, with 200-seat aircraft by 2040.
