In the current global environment where self-sufficiency is gaining importance, Singapore, a country with limited land mass and natural resources, is focusing on strengthening its energy security through diversification and innovation. By importing over 90% of its food from various sources and relying on multiple water supply methods, Singapore has demonstrated the power of diversification in ensuring resilience. In terms of energy, the country heavily relies on natural gas currently but is actively expanding into renewable sources like solar, hydrogen, and nuclear power to achieve its net-zero ambitions by 2050. Singapore's National Hydrogen Strategy aims to have hydrogen meet up to half of the country's power needs by 2050. The upcoming hydrogen-blended gas facility at Pulau Seraya Power Station is a significant step in this direction. Grid investments are crucial for Singapore's energy security strategy, as they enable the integration of various energy sources, ensure uninterrupted electricity supply, and manage the growing demand driven by factors like digitalization and electric vehicles. The country's grid infrastructure, supported by advanced technologies like AI and high-voltage direct current transmission, plays a vital role in balancing supply and demand efficiently. Grid investments not only support decarbonisation efforts but also enhance national security by reducing exposure to price volatility and geopolitical risks. Overall, Singapore's emphasis on diversification, renewable energy sources, and grid infrastructure investments showcases a positive and proactive approach towards ensuring national resilience and sustainability.
