For such a small island state, Singapore is thinking big about the expansion of Changi Airport. A project to create a fifth passenger terminal and a third runway will cost an estimated $10 billion. Developers have prepared a total area of 1,080 hectares for the project. When completed, the Changi East development will boost the airport’s capacity by 50 million passengers per annum to a total 140 million.
Plans call for the two-phase development to become operational in the mid-2030s. Construction paused for two years during the pandemic, allowing for a design review, according to the government-owned Changi Airport Group (CAG). Design features include substantial employment of robotics, fixed ground power, and provision for sustainable aviation fuel. It could feature hydrogen fueling as well, as CAG has partnered with Airbus, the Civil Aviation of Singapore, and gas company Linde to study the subject.
