Hydrogen’s Role in Singapore’s Aviation Decarbonization

Our Bureau - : Feb 22, 2024 - : 6:15 pm

Singapore, Feb. 22, 2024 – The Singapore Hydrogen Cooperation Committee acknowledges hydrogen fuel’s potential in the state’s aviation decarbonization efforts.

Formed after the Cooperation Agreement signing by Airbus, Changi Airport Group, Civil Aviation Authority of Singapore (CAAS), and Linde in Feb. 2022, the committee has assessed regional and local hydrogen demand and supply, supply chain and infrastructure needs, and potential considerations for establishing a hydrogen ecosystem for aviation in the city-state.

The technology to use liquid hydrogen for aircraft is under development and will be applied to future large commercial aircraft. Early technical feasibility studies ensure Singapore’s readiness for incorporating liquid hydrogen in its aviation decarbonization strategy.

“Stakeholders in the Asia-Pacific region are increasingly taking greater interest in making significant investments into hydrogen, developing new technologies and establishing supply chains. Together with our partners, we recognise the potential of hydrogen becoming a longer-term decarbonisation pathway for aircraft operations, complementing sustainable aviation fuel, in support of our transition towards net zero by 2050,” said Sabine Klauke, Chief Technology Officer, Airbus.

As part of the study, infrastructure scenarios supporting the progressive deployment of liquid hydrogen at Changi Airport were identified. Singapore’s aviation sector may consume up to 50 tonnes of liquid hydrogen daily from the 2040s, and up to 600 tonnes per day beyond 2050.

Mr Han Kok Juan, Director-General of CAAS, said, “The International Civil Aviation Organization Member States have adopted a collective long-term global aspirational goal of net-zero carbon emissions by 2050. While the near-term focus is on the wider adoption of sustainable aviation fuels in aircraft operations, hydrogen can potentially play a complementary role as a sustainable energy fuel in the longer term. CAAS has shared some of the key findings from the study with relevant government agencies for longer-term national planning for demand of hydrogen and will continue to monitor signposts around the development of hydrogen technology for aircraft operations.”

Ms Poh Li San, Senior Vice President, Terminal 5 Specialised Systems, Changi Airport Group said, “Hydrogen technology is still in its nascency, with many uncertainties and the industry is working hard to study aspects such as operations, safety, regulation and economics. These need to be examined further. As the aviation industry progresses on its sustainability journey, it is prudent to take a phased approach  as air hubs study how best to support the use of hydrogen by aircraft.”

“Hydrogen has a key role to play in the global clean energy transition. In aviation, hydrogen shows promise on two fronts: reducing aircraft emissions in the air, and decarbonising airside ground activities,” said John Panikar, EVP and CEO APAC, Linde. “Linde has over 100 years of experience with hydrogen. Our business spans the entire global hydrogen value chain and we look forward to leveraging our capabilities to further develop the promise of hydrogen in aviation.”

The committee agreed to monitor hydrogen technology development around key signposts to enable hydrogen-powered aviation when technology, regulations, infrastructure, and supply chains are ready.
