Sarawak, Malaysia is intensifying its renewable energy efforts with ambitious plans to expand its electricity capacity to 10 gigawatts by 2030 and 15 gigawatts by 2035, solidifying its position as a green energy hub in Southeast Asia. Premier Datuk Patinggi Tan Sri Abang Johari Tun Openg highlighted Sarawak's vision to become the 'Battery of ASEAN' during a lecture in Singapore. The state's strategy involves developing hydropower, enhancing cross-border electricity connectivity through the ASEAN Power Grid project, and ramping up green hydrogen production in collaboration with key Asian partners. Despite the focus on hydrogen, Sarawak recognizes the need for additional measures for full decarbonization, leading to the integration of Carbon Capture, Utilization, and Storage (CCUS) technology to curb emissions in challenging industries. The state is also actively engaged in Malaysia-Japan cooperation on low-carbon ammonia production, emphasizing the shift towards cleaner energy solutions. Moreover, Sarawak is advancing in low-carbon fuel initiatives, with projects like the Sarawak Methanol Complex and the development of a Green Methanol Plant aimed at supporting sustainable fuel production for various industries. This aligns with the broader decarbonization strategy that includes leveraging renewable energy sources and optimizing natural gas utilization while focusing on industrial decarbonization. The state's commitment to sustainable energy extends to biomass energy production, where agricultural waste is transformed into biofuels, biogas, and syngas to aid in industrial decarbonization efforts. Research into microalgae-based Sustainable Aviation Fuel (SAF) also offers promising avenues to reduce emissions in the aviation sector. Sarawak's green energy transformation spans beyond energy production, encompassing urban development and digital transformation to foster smart and eco-friendly cities. Through these holistic initiatives, Sarawak continues to lead ASEAN's transition towards sustainable energy and industrial decarbonization, setting a noteworthy example for the region.
