Thailand is undergoing a significant energy transition towards clean and sustainable sources, as outlined in the country's Power Development Plan. With a focus on renewable energy, particularly solar power, Thailand aims to introduce hydrogen energy into electricity production by 2030. The plan also includes the deployment of small modular nuclear reactors to diversify energy sources. Challenges such as ensuring energy security and affordability are being addressed by gradually transitioning to natural gas as a primary energy source. Advanced technologies like battery energy storage systems are seen as crucial for stabilizing the energy grid. Leading corporations in Thailand, including Bangchak Group and PTT, are actively promoting hydrogen fuel adoption and carbon capture projects to reduce carbon emissions and achieve net zero by 2065. Industry experts emphasize the importance of clean hydrogen energy, AI advancements, and the potential of nuclear energy in Thailand's sustainable development. Though initial costs pose a challenge, significant investments from both the public and private sectors are expected to drive the commercialization of clean hydrogen energy by 2040.
