Focus on the "China Natural Gas Development Report 2025"

Guoke Hanhai's Laser Technology Safeguards Safe and Low-Carbon Development of the Natural Gas Industry

According to the official announcement on the website of the National Energy Administration on August 29, the "China Natural Gas Development Report (2025)" (hereinafter referred to as the "Report") was officially released. It comprehensively sorts out the development trends of the domestic and international natural gas industry in 2024 and clarifies the reform direction and development prospects for the future. Against the backdrop of medium-to-high speed growth in natural gas consumption, continuously consolidated supply capacity, and accelerated low-carbon transformation, Guoke Hanhai, with laser monitoring technology as the core, provides precise sensing solutions for the entire natural gas industry chain from three dimensions—safety assurance, low-carbon emission reduction, and digital-intelligent upgrading—to support the high-quality development of the industry.

Consumption Growth and Structural Optimization: Laser Guards Gas Safety in Multiple Scenarios

In 2024, China's natural gas consumption increased by 7.3% year-on-year, accounting for 8.8% of primary energy consumption. Urban gas, industrial fuel, and power generation gas have become the core growth drivers. The record-high sales of LNG heavy trucks drove the growth of transportation gas, industrial equipment upgrades boosted fuel gas demand, and the demand for gas-fired power peak regulation led to a 9.5% year-on-year increase in power generation gas. The upgraded gas demand in different scenarios has put forward higher requirements for "full-chain safety monitoring."

Targeting the risk characteristics of each link in the natural gas industry chain, Guoke Hanhai provides customized laser monitoring solutions:

Urban gas sector: In residential and commercial gas usage scenarios, wall-mounted passive laser monitoring terminals are deployed. These terminals require no power supply, eliminating the risk of electric sparks and enabling real-time monitoring of methane leakage. For example, in the Hefei Chaohu LNG refueling station project, 6 optical sensing terminals cover key areas such as gas storage tanks and refueling machines, responding to ppm-level leaks within 10 seconds and building a solid safety barrier for LNG heavy truck refueling and residential gas use.

Industrial fuel sector: To meet the natural gas usage needs of industrial kilns and heating furnaces, fixed reflective laser gas telemetry instruments form a 100-meter monitoring optical path to accurately capture micro-leaks at pipeline interfaces and valves. Taking the Jinan Refining & Chemical project as an example, the equipment covers a 1,000-meter pipe rack, real-time monitoring hydrogen sulfide and methane to avoid safety accidents caused by industrial gas leakage.

Power generation gas sector: For the gas supply links of gas-fired peak regulation power stations, the original wall-mounted passive laser monitoring terminals are directly embedded in high-temperature gas combustion chambers to real-time monitor trace methane concentrations, ensuring the safe and stable operation of gas-fired power units. Meanwhile, they can synchronously monitor ammonia escape and gas leakage in the desulfurization and denitrification links, guaranteeing safe and efficient power generation processes.

Consolidated Supply Capacity and Improved Facilities: Laser Technology Fills Monitoring Blind Spots

The Report points out that in 2024, China's natural gas output reached 246.5 billion cubic meters (a year-on-year increase of 6%), and unconventional natural gas output exceeded 100 billion cubic meters. With the full commissioning of the China-Russia Eastern Route and the commissioning of the 4th West-East Gas Pipeline, the total length of national long-distance transmission pipelines exceeded 128,000 kilometers, and the newly added unloading capacity of LNG receiving terminals reached 43.68 million tons per year. As upstream exploration and development advance to deep and ultra-deep layers, and the midstream pipeline network forms a "national integrated network," scenarios such as "deep underground, long-distance transmission, and outdoor areas without power supply" that are difficult to cover by traditional monitoring methods have become new challenges for safety assurance.

Guoke Hanhai addresses scenario-specific challenges with various types of laser equipment:

Upstream exploration and development: Targeting the harsh mining environment of high-sulfur deep shale gas in the Sichuan Basin, laser equipment withstands high temperature, high pressure, and strong corrosion, accurately monitoring hydrogen sulfide and methane leakage at wellheads. For example, in the Southwest Oil & Gas Field project, 6 sets of fixed reflective laser telemetry instruments achieve ppm-level detection of 50% concentration hydrogen sulfide, avoiding "invisible risks" in deep underground mining.

Midstream pipeline transportation: For long-distance pipelines such as the China-Russia Eastern Route and the 4th West-East Gas Pipeline, fixed reflective laser equipment forms a 1,000-meter linear monitoring optical path. As seen in the Jinan Refining & Chemical pipe rack project, laser beams span above the pipelines to real-time capture methane leakage during transportation, providing data support for the safe operation of the "national integrated network."

LNG receiving terminals and gas storage facilities: IoT laser monitoring instruments (solar-powered type) are deployed to solve the monitoring problem in outdoor areas without power supply. For example, in the Tianjin LNG receiving terminal SCV platform project, the equipment relies on solar power to continuously monitor gas emissions after torch combustion and storage tank leakage, eliminating the need for manual inspections and realizing real-time data upload to the management platform. For ultra-large LNG storage tank groups, fixed scanning laser telemetry instruments are equipped to achieve 360-degree all-round coverage of the storage tank area, capturing fugitive emissions from breathing valves and flanges.

Accelerated Low-Carbon Transformation: Lasers Empower Carbon Monitoring and Emission Reduction

The Report emphasizes that the natural gas industry is accelerating the pace of "greening and carbon reduction." Oil and gas fields are promoting multi-energy complementarity of "solar + wind + natural gas," while the downstream is exploring technologies such as natural gas-hydrogen blending and CCUS (Carbon Capture, Utilization, and Storage). Meanwhile, the implementation of the "Interim Regulations on the Administration of Carbon Emission Trading" requires enterprises to improve the quality of carbon emission data. Against this backdrop, precise gas monitoring has become the core support for carbon accounting and verification of emission reduction effects.

Guoke Hanhai's laser technology provides "hard data" for the low-carbon transformation of the natural gas industry:

Accurate carbon emission accounting: In-situ penetrating laser gas detectors can simultaneously monitor greenhouse gases such as carbon monoxide, carbon dioxide, and methane. For example, in the Henan Jiaozuo Waste Incineration Power Plant project, the equipment real-time captures carbon dioxide emission data after natural gas combustion, and accurately calculates carbon emissions in combination with power generation, providing traceable data support for enterprises to participate in carbon market transactions.

Methane leakage control: As a greenhouse gas with a global warming potential 28 times that of carbon dioxide, the control of methane fugitive emissions is a key focus of low-carbon efforts. Guoke Hanhai's laser equipment achieves ppm-level detection of methane. For example, in the Sinopec Oil & Gas Field project, it real-time monitors methane leakage from gas wells and gathering stations, helping enterprises reduce emissions of "potent greenhouse gases."

Verification of emission reduction projects: For emission reduction projects such as natural gas-hydrogen blending and CCUS, laser equipment monitors changes in gas concentrations before and after transformation. For example, in the Guangdong H-class natural gas-hydrogen blended power generation unit project, laser equipment real-time monitors the hydrogen blending ratio and carbon dioxide emissions after combustion, quantifies the emission reduction effect of the project, and provides data support for CCER (Certified Emission Reduction) verification.

Digital-Intelligent Integration Trend: Laser Data Connects Full-Chain Management

The Report proposes that the integration of artificial intelligence and the oil and gas industry is accelerating, driving industrial digital-intelligent upgrading. Guoke Hanhai's laser monitoring system is not an isolated "data collection tool" but a "front-end sensing node" deeply integrated with the full-chain natural gas management platform:

Real-time data transmission: Laser equipment uploads data such as leakage concentration and carbon emissions to enterprise production management platforms and carbon management platforms in real-time through optical fiber or wireless communication, avoiding errors caused by "secondary entry."

Automatic accounting and analysis: Combined with data such as natural gas output, pipeline transmission volume, and power generation, laser monitoring data can automatically calculate unit product energy consumption and carbon emissions, generating reports that comply with industry standards.

Full-process evidence preservation: Data is preserved using blockchain technology to ensure immutability, meeting the data supervision requirements of the "Interim Regulations on the Administration of Carbon Emission Trading" and providing a traceable data chain for regulatory authorities and enterprises.

With Laser Precision, Accompanying the Natural Gas Industry to Steady and Long-Term Development

The "China Natural Gas Development Report 2025" outlines the development blueprint of the natural gas industry featuring "safe supply guarantee, low-carbon transformation, and digital-intelligent upgrading," and precise front-end monitoring is the foundation for realizing this blueprint. Guoke Hanhai will continue to deepen the integration of laser technology with natural gas scenarios, from upstream deep underground exploration to downstream terminal utilization, and from safety monitoring to carbon management support. With the "precision of light," it will safeguard the high-quality development of the natural gas industry and contribute to the realization of the "dual carbon" goals and energy security strategies.
