Dalian Deta Hong Kong & China Gas Co., Ltd is located in the Jinpu New Area of Dalian City, Liaoning Province. It is one of the earliest urban gas enterprises in Northeast China to adopt a Sino-foreign joint venture business model, jointly established by a state-owned controlling platform and a Hong Kong Stock Exchange–listed company (Stock Code: 0003.HK). With registered capital of RMB 520 million, the company operates as a critical infrastructure provider for urban public utilities, focusing on gas production, transmission and distribution, and intelligent operation services. Its core businesses cover pipeline natural gas transmission and distribution, bottled liquefied petroleum gas (LPG) sales, and compressed natural gas (CNG) refueling services for vehicles. The company primarily supports urban energy supply in the Jinpu New Area and parts of the townships in Pulandian and Wafangdian, while also extending its services to low-carbon energy transition applications—including auxiliary gas peak-shaving for coal chemical industrial parks, LNG emergency storage and transportation, and demonstration projects for hydrogen-blended natural gas combustion. Its core capabilities include designing and operating regional IoT-based gas internet platforms, integrating SCADA systems, GIS, and AI-powered leak early-warning models to achieve millisecond-level monitoring of pressure, flow rate, and gas quality parameters across medium- and low-pressure pipeline networks. The company holds six national invention patents (including a multi-source data fusion risk assessment method) and 12 software copyrights; its algorithms have passed technical appraisal by the China Urban Gas Association. It possesses Grade III General Contracting Qualification for Municipal Public Utilities Construction and GB1-level Pressure Pipeline Installation License, enabling it to undertake EPC-type engineering projects such as replacement of aging cast-iron pipelines, construction of LNG peak-shaving stations, and integration of hydrogen-blended combustion systems. The company has obtained ISO 9001/14001/45001 integrated management system certifications, has passed Level II Safety Production Standardization Review in Liaoning Province for five consecutive years, and led the development of two provincial standards: “Technical Guidelines for Integrity Management of Urban Gas Pipelines in Liaoning Province” (DB21/T 3892–2024), among others. Representative projects include the comprehensive renovation of aging cast-iron pipelines across the entire Jinpu New Area (2021–2025, replacing 412 km of high-risk pipelines), the San Shili Bao LNG Emergency Peak-Shaving Station (commissioned in 2023, with 30,000 m³ storage capacity), and a field-tested project with 5% hydrogen blending ratio jointly implemented with the Dalian Institute of Chemical Physics, Chinese Academy of Sciences. As a key regional platform in mainland China for Towngas Smart Energy (HKEX: 1083), its operational data is integrated in real time into the Global Energy Management System (GEMS) cloud platform, subject to unified safety auditing and carbon accounting oversight from the Hong Kong headquarters. Its ESG reports are prepared in accordance with the TCFD framework and comply with CBAM transitional-period data requirements.
