In terms of energy efficiency, Thailand has implemented amendments to the "Energy Management Act", mandating large industrial enterprises to conduct energy audits and setting a target to reduce energy intensity by 30% by 2030. Additionally, Thailand has introduced carbon pricing mechanisms, imposing carbon taxes on high-carbon enterprises starting from 2026, with an initial tax rate of 100 Thai baht per ton of CO2 equivalent, which will be increased annually.
Notably, the Thai government has also introduced the "Energy Transformation Promotion Act", providing tax incentives, land use facilitation, and financial support for energy transformation projects. The bill particularly emphasizes supporting the transformation of traditional energy enterprises, with state-owned enterprises like PTT Public Company Limited required to develop detailed decarbonization roadmaps and gradually increase the proportion of renewable energy investments.
Technological Breakthroughs and Innovative Projects
In terms of technological innovation, Thailand's energy transformation sector has achieved a series of breakthroughs. Floating solar technology utilizes water resources such as reservoirs and lakes, saving land resources while improving power generation efficiency, and has been successfully applied in many regions such as Sukhothai and Chiang Mai. In the first half of 2026, Thailand announced the construction of the world's largest floating solar power plant with a capacity of 1.2GW, expected to be connected to the grid in 2027.
Energy storage technology has become a key support for Thailand's energy transformation. To address the intermittency of renewable energy, Thailand is accelerating the development of multiple technology paths including battery energy storage, pumped hydro storage, and compressed air energy storage. The government has launched the "Energy Storage Demonstration Project Program", supporting the construction of energy storage demonstration projects with a total capacity of 2GWh, exploring energy storage solutions suitable for Thailand's national conditions.
In the hydrogen energy sector, Thailand has formulated the "National Hydrogen Energy Strategy Roadmap", aiming to build a green hydrogen production capacity of 500,000 tons/year by 2030. In 2026, Thailand, in cooperation with countries like Japan and South Korea, launched the first large-scale green hydrogen demonstration project in Southeast Asia, utilizing Thailand's abundant solar resources to produce green hydrogen and exploring applications of hydrogen in industry, transportation, and power generation.
