PTT Plc, a key player in Thailand's energy sector, is delving into green initiatives at its gas-fired power plant in Map Ta Phut, Rayong. The company is keen on utilizing hydrogen fuel to curb carbon dioxide emissions within its businesses. In a bid to combat global warming, PTT is eyeing collaborations with Mitsubishi Heavy Industries to study hydrogen's potential as a fossil fuel alternative and with Sunyo Petrochemical Industries to develop eco-friendly raw materials. Mitsubishi's technology advancements in hydrogen usage for electricity generation, such as the co-firing technique, showcase a promising future. While hydrogen's benefits in emission reduction are acknowledged, challenges like high costs and extensive investments remain. PTT's strategic partnerships with Japanese firms signal a commitment to environmental sustainability and innovation in the petrochemical industry. The envisioned shift towards hydrogen-based machinery and raw materials signifies a proactive step towards achieving carbon neutrality and fostering greener practices in the region.
