Singapore is aiming to peak carbon emissions by 2030 and achieve net-zero emissions by 2050, with a focus on decarbonizing the energy supply in the power sector. Hydrogen is being explored as a low-carbon alternative to transform the fuel mix. Despite being a clean fuel that produces water as a by-product when combusted, challenges exist in using hydrogen for power generation. The article discusses the history of hydrogen usage in various industries and countries like China and Japan. The production and transportation of clean hydrogen face hurdles such as high costs, energy intensity, and infrastructure requirements. While currently more expensive than natural gas, clean hydrogen holds promise for decarbonization efforts. Singapore is investing in developing a legislative framework, research projects, and technological capabilities to harness hydrogen's potential. Initiatives include exploring ammonia supply chains, inviting companies to build hydrogen-compatible power plants, and awarding funds for low-carbon energy research. Singapore's vision includes hydrogen playing a significant role in its energy mix towards a net-zero future, contingent on technological advancements and international cooperation.
