CIMC Enric’s Linggang Steel-Coke Integration Project Marks China’s First 100% Coke Oven Gas Conversion Facility

Breakthrough clean energy project in Liaoning produces LNG, blue hydrogen and synthetic ammonia, signalling a new phase in industrial decarbonisation

HONG KONG, November 25, 2025 – CIMC Enric Holdings (Stock Code: 3899.HK) has announced the official commencement of production at its Linggang Steel-coke Integration Project — China’s first facility capable of fully converting coke oven gas into clean-energy products. Jointly developed with Angang Steel Energy Technology, the landmark project forms a central pillar of Lingyuan Iron & Steel Group’s broader push to modernise its coke oven systems and advance green transformation.

Located in Lingyuan, Chaoyang City, the project represents a major milestone for Northeast China’s industrial base. Designed to produce 140,000 tonnes of LNG, 24 million cubic metres of blue hydrogen, and 60,000 tonnes of synthetic ammonia annually, the facility demonstrates how traditionally high-emission industries can generate high-value clean fuels for regional use. These outputs will support greener transport, industrial production and chemical applications — reflecting a step-change in how steel industry by-products are utilised.

A Proven Model for Industrial Green Transition

The Linggang project is the second large-scale collaboration between CIMC Enric and Angang Steel Energy Technology in Liaoning, following the successful 2024 launch of a similar steel-coke integration project in Bayuquan, Yingkou. With over a year of stable operation, that earlier project provided a strong foundation for scaling the model across the province.

While Northeast China has long emphasised solar, wind, biomass and other renewable projects, core heavy industries such as steelmaking have largely been viewed as emissions challenges, rather than contributors to clean-energy generation. CIMC Enric’s integration model overturns this narrative by converting coke oven gas — a common steelmaking by-product — into LNG, hydrogen and liquid ammonia for local industrial and mobility use.

The company says this approach creates a direct link between the traditional steel sector and regional clean-energy ecosystems, accelerating Liaoning Province’s industrial green transition while demonstrating replicability for other steel clusters.

Significant Emissions Reductions and Industry-Leading Execution

Spanning nearly 28 hectares, the Linggang facility is equipped with advanced processing technologies. Its hydrogen output reaches 99.9999% purity, meeting fuel-cell standards, while its LNG will replace diesel in heavy-duty trucks, vessels and locomotives, and substitute coal for industrial and power-sector consumers.

The environmental upside is substantial. Annual emissions reductions are expected to include – 402,500 tonnes of CO₂, 226.3 tonnes of SO₂, 1,747.2 tonnes of NOₓ.

CIMC Enric Engineering Technology, a Group subsidiary, executed the project using a full turnkey model — delivering process design, installation and construction. Completed in just 10 months, the project sets a new benchmark for construction efficiency in the sector. Key equipment, including LNG storage tanks, was manufactured within the Group’s supply chain, underscoring CIMC Enric’s end-to-end capabilities across the clean-energy value chain.

Digital Integration for Full-Lifecycle Carbon Management

A standout feature of the Linggang project is its integration with CIMC Enric’s intelligent digital platform, which uses AI, IoT and cloud technologies to track and optimise energy flows from production to utilisation. The system captures real-time Scope 1, 2 and 3 emissions data across upstream, midstream and downstream activities, enabling full-lifecycle carbon management for project partners.

Building on the hydrogen transport “closed-loop” created at the Yingkou project — where hydrogen-powered heavy-duty trucks are already in daily operation — the platform acts as an intelligent command centre to enhance safety, efficiency and decarbonisation across the energy system.

Expanding a Scalable, Exportable Model

With Linggang now operational, CIMC Enric aims to expand the steel-coke integration model across Liaoning and other major steel-producing regions in China. The Group also sees strong potential to scale the approach internationally, particularly in markets seeking rapid pathways to industrial decarbonisation.

Backed by CIMC Enric’s global manufacturing network and leadership in LNG, hydrogen and cryogenic technologies, the company says the project provides a viable template for steelmakers and policy planners pursuing cleaner, circular energy solutions.

As China accelerates heavy-industry transformation and global markets push for deep emissions cuts, the Linggang project demonstrates how cross-sector collaboration can turn industrial emissions into green-energy opportunities — and how traditional manufacturing clusters can anchor the next wave of low-carbon innovation.
