Aviation is a significant contributor to the global economy, and has become increasingly popular in recent years due to the emergence of low-cost carriers and the surge in leisure travel. Despite efforts to decrease its environmental footprint, the air travel industry has seen an annual rise in pollution emissions – apart from in 2020 when the sector was forced to a halt due to the pandemic.<\/p>\n

Air transport is a major contributor to greenhouse gas emissions, accounting for 3.8% of total European Union (EU) emissions according to the European Environment Agency. This ranks it as the third most polluting mode of transport after land transport<\/a> (20,5 %) and\u00a0 maritime transport<\/a> (4 %).<\/p>\n

According to the International Civil Aviation Organization, commercial flights emitted approximately 900 million tonnes of CO2<\/sub> in 2019. Given that this industry is projected to grow worldwide, there is a commitment from leading players to undertake a process of decarbonisation.<\/p>\n

The search for sustainable alternative fuels<\/strong><\/h2>\n

The aviation industry has embarked on a path of no return towards sustainability through efficiency and emissions reduction.<\/p>\n

Significant progress has been made recently in engine technology, air traffic management and the use of sustainable fuels. All of this is necessary to achieve goals such as the European Union\u2019s target to make 63% of jet fuel sustainable by 2050 or IATA\u2019s target to reduce the sector\u2019s emissions by 50% by 2050.<\/p>\n

The aviation industry has embarked on an irreversible trajectory towards sustainability, focusing on increasing efficiency and reducing emissions<\/p>\n<\/blockquote>\n

There are several types of fuels that are considered sustainable for aviation, such as Biojet, a biofuel made from biological waste, or E-Jet, a synthetic fuel made from CO2<\/sub> removed from the atmosphere and industry, along with renewable hydrogen.<\/p>\n

Although these proposals make progress towards reducing emissions, it is also important to develop other alternatives in the medium and long term. And here renewable hydrogen is one of the most important options for two reasons:<\/p>\n
