P2G (Power-to-Gas) is one of the next-generation energy storage technologies. It utilizes surplus electricity that cannot be accommodated by the power grid—such as renewable energy from solar and wind—to produce hydrogen (H₂) through water electrolysis. The produced hydrogen can be further reacted with carbon dioxide (CO₂) to synthesize methane (CH₄). This process enables the recycling of CO₂ emitted from sources such as thermal power plants, making P2G a key technology for achieving carbon neutrality and establishing a circular energy system.

1) Successfully executed the entire process—including permitting and licensing, risk assessment, and construction—of Korea’s first P2G plant

2) Performed BOP (Balance of Plant) design and construction for the Ulsan P2G plant (500 kW) and PEM water electrolysis system (1 MW)

3) Completed the design and construction of Korea’s largest P2G plant (2 MW) in Naju
