Doosan Enerbility Wins Contract to Build LNG Storage Tanks in South Korea

The Korea Gas Corp. (KOGAS) awarded Doosan Enerbility KRW 560 billion to build three LNG storage tanks and ancillary facilities, each with 270,000-kiloleter capacity, for the Dangjin LNG Terminal Phase 2 project in South Chungcheong, South Korea. Construction will begin in September 2025, with completion anticipated by December 2029.

“Our track record of having successfully carried out numerous LNG storage tank projects in the Korean domestic market played a role in our recent project win,” said Hyeonho Lee, CEO of Doosan Enerbility’s Plant EPC Business Group. “We will carry out the Phase 2 work, as we did for Phase 1, to contribute to the supply and demand balancing of natural gas.”

Building out the Dangjin LNG storage tank infrastructure falls under the broader LNG Production Base Project at the Dangjin Seokmun National Industrial Complex, which intends to improve South Korea’s LNG supply-demand balance. During Phase 1 in 2021, Doosan Enerbility completed roof air-raising work for four LNG tanks and is currently executing internal construction work.

Following the Phase 2 award, the company is building seven LNG storage tanks for the Dangjin LNG terminal, with additional construction work secured and/or completed for the Incheon, Pyeongtaek, and Samcheok terminals.

Gas Turbine Components

In early May 2025, Doosan Enerbility and HD Hyundai Marine Engine signed a two-part memorandum of understanding to develop precision-casting manufacturing technologies for gas turbines and prototype blade materials, i.e., rotating airfoils connected to the rotor. According to the MoU:

• Doosan Enerbility will design and conduct quality assessments for each gas turbine blade
• HD Hyundai Marine Engine will develop and manufacture precision-casting materials

Doosan Enerbility, with this partnership, intends to strengthen South Korea’s domestic supply chain for gas turbine components and, as a result, will meet the increasingly high global demand for gas turbines. The contract to develop prototype blade materials aims to increase Korean suppliers’ gas turbine parts capacity, allowing global users to tackle the energy addition and gas turbine supply challenge.

Waste-to-Energy Plant

In mid-February 2025, under a contract with PAPREC ENGINEERING, Doosan Škoda Power agreed to supply a DST-G10 steam turbine, generator, gearbox, and additional auxiliary equipment for the new Pierrefonds waste-to-energy (WtE) plant on Réunion Island—a French territory. The contract also includes technical advisory services for construction and commissioning.

The Pierrefonds WtE plant, expected to be operational by 2026, will process up to 148,000 tons of waste and generate 121,000 MWh of electricity per year—the annual power equivalent of 83,000 inhabitants, or 10% of Réunion’s population. The facility will also reduce the dependency on landfills, recovering 130,000 tons of household waste to avoid burial. The single-casing, 19-MW DST-G10 steam turbine is designed for mounting on a frame containing an oil tank, gearbox, insulation, and other requisite instrumentation and equipment.
