I. Background: Driven by Both Energy Costs and "Dual Carbon" Goals
Against the backdrop of continued pressure on global manufacturing, energy issues have evolved from a "cost item" to a "core competitiveness factor." On the one hand, fluctuating energy prices and unstable supply chains place sustained cost pressures on energy-intensive industries; on the other hand, the continuous implementation of policies such as carbon neutrality and carbon peaking is forcing industrial enterprises to re-examine their energy structures.
In this context, the industrial energy system is undergoing a profound transformation—a systematic adjustment from high energy consumption and high emissions to high efficiency, low carbon emissions, and intelligent operation.
II. Structural Shift from "Single Energy Source" to "Multi-Energy Synergy"
The traditional industrial energy structure is dominated by coal, fuel oil, and a single electricity system, resulting in low efficiency and inefficient dispatching. The current adjustment trends are mainly reflected in the following aspects:
1. Significantly Improved Electrification Level
● Industrial heating, transmission, and drive systems are accelerating their transformation from fuel-powered to electric-driven and electric-heated systems.
● High-efficiency motors, frequency converters, and servo systems are replacing traditional mechanical structures.
● Electrification lays the foundation for subsequent green electricity access and intelligent scheduling.
2. Clean Energy Gradually Entering the Industrial Sector
● Rapid deployment of photovoltaic, wind power, and energy storage systems in factories.
● Hydrogen energy is entering the pilot stage in high-energy-consuming industries such as steel and chemicals.
● An integrated energy structure of "source-grid-load-storage" is being formed.
3. Multi-Energy Complementarity and Flexible Scheduling
● Multi-energy systems (electricity, heat, cooling, and gas) are operating collaboratively.
● Dynamic optimization is achieved through energy management systems (EMS).
● Peak loads are reduced, and overall energy efficiency is improved.
III. Core Technology: Efficiency Improvement No Longer Relies on Single Equipment
The "high-efficiency" transformation of the industrial energy structure is no longer a single-point technological upgrade, but a systemic engineering project.
1. High-efficiency equipment as the basic unit
● IE4/IE5 high-efficiency motors
● High power density frequency converters
● Low-loss power electronic devices (SiC, GaN)
These devices directly reduce energy consumption per unit of output, forming the "foundation" for energy structure optimization.
2. Deep involvement of automation and control systems
● DCS/PLC achieves precise control of process energy consumption
● Adaptive load adjustment reduces no-load and overload losses
● Real-time data supports energy efficiency analysis and optimization
3. Data-driven energy management
● Energy data moves from "statistics" to "real-time sensing"
● AI algorithms are used to predict loads and optimize operating strategies
● Digital twins are used to simulate operating effects under different energy structures
IV. Green transformation path: From "emission reduction" to "sustainable operation"
Industrial green transformation is not just about simple emission reduction, but about building a long-term sustainable energy operation system.
1. Visualization and Quantification of Carbon Emissions
● Establish carbon emission models at the equipment, production line, and factory levels.
● Provide the technological foundation for carbon trading and carbon auditing.
2. Integration of Low-Carbon Processes and Renewable Energy
● Utilize green electricity to reduce carbon intensity per unit product.
● Improve overall system efficiency through waste heat recovery and waste energy reuse.
3. Compliance and Competitiveness in Parallel
● Meet the ESG requirements of international customers.
● Enhance the company's competitive position in the global supply chain.
V. Industry Impact: High-Energy-Consuming Industries Lead the Transformation
The following industries are particularly prominent in energy structure adjustment:
● Steel, Cement, and Chemicals: Have the greatest potential for energy saving in high-energy-consuming scenarios.
● Data Centers and Semiconductor Manufacturing: Have extremely high requirements for power stability and green energy.
● High-End Equipment Manufacturing: High efficiency and low energy consumption are the core of product competitiveness.
Changes in energy structure are driving upgrades in equipment selection, system architecture, and control strategies.
VI. Conclusion: Energy Structure Upgrading is a Long-Term Project and a Certain Trend
It is foreseeable that future industrial competition will not only be a competition of production capacity and cost, but also a competition of energy efficiency, carbon intensity, and system intelligence.
The industrial energy structure is shifting towards greater efficiency and greener practices. This trend is not a temporary choice, but rather an inevitable path for the manufacturing industry to achieve high-quality and sustainable development.
For industrial enterprises, the sooner they complete the upgrade of their energy structure and control systems, the more proactive they will be in the next round of industrial competition.
