Natural gas power generation as an important mode of electricity production plays a key role in the transformation of the global energy structure. Here is a brief analysis from several dimensions:
Core Advantages
Significantly better environmental protection than coal
Low carbon emissions: CO2 emissions after combustion are only 50%-60% of coal power, which is an important transition energy to replace traditional coal power and achieve carbon reduction.
Low pollution: There is little sulfur oxides (SOx) and dust, and nitrogen oxides (NOx) emissions are significantly lower than coal power.
Water saving advantages: combined cycle power plant water consumption is about 40%-60% lower than equivalent coal power.
Flexible and efficient operation
Quick start-stop: the gas turbine can reach full load from cold in 30 minutes (coal power takes several hours), perfectly matching the volatility of wind power and photovoltaics.
Strong adjustment capability: the response rate to load changes is fast, which is the ideal choice for peak grid adjustment and security of power supply.
High energy efficiency: Modern gas-steam combined cycle power plants (CCGT) can be more than 60% efficient, far exceeding traditional coal power (about 35%-45%).
Investment and occupancy advantages
Short construction cycles: The modular design makes the construction cycle typically 2-3 years (coal power takes 4-6 years).
Lower initial investment: The cost per kilowatt is typically lower than nuclear, hydro and supercritical coal power.
Small area: about 1/3 of the same size coal power plant, the choice of site is more flexible.
Key challenges
Fuel costs and supply security
Strong price volatility: Natural gas prices are vulnerable to geopolitical and market demands (e.g. the European energy crisis of 2022).
High foreign dependence: Import dependence in countries such as China is high, and energy security risks need to be carefully managed.
Infrastructure bottlenecks: insufficient construction of pipelines and LNG receiving stations may limit resource allocation.
Positioning dilemmas under long-term climate goals
Still for fossil energy: Lifecycle-wide carbon emissions are significantly higher than renewable energy, not achieving the ultimate goal of carbon neutrality.
Methane leakage: Methane (strong greenhouse gas) leakage during mining and transportation needs to be strictly controlled.
Transition pressure: In the carbon neutralization path, it is necessary to define the time limit of its “bridge” role to avoid locking the carbon footprint.
Economy is constrained by multiple factors
Fuel costs account for a high proportion (up to 70% of total costs), and competitiveness declines sharply when gas prices rise.
China market electricity tariff mechanism: lack of mature capacity electricity tariff and ancillary services market, it is difficult to fully reflect peak value adjustment.
Application Scenarios and Core Values
Supporting large-scale grid integration of renewable energy
Provide flexible backup power for wind power and photovoltaics to solve their intermittent problems.
Regional energy security
Build distributed power stations in load centers to relieve grid transmission pressure and improve power supply resilience (e.g. Guangdong, Hong Kong and Macau Greater Bay Area).
Urban Heating and Industrial Collaboration
Combined heat and power generation (CHP) achieves energy gradient utilization, with integrated energy efficiency exceeding 80%.
Replacing old coal
Accelerate coal conversion in areas with severe air quality to achieve carbon reduction synergies.
Technology direction
Hydrogen doping / pure hydrogen combustion technology: gradually increase the proportion of hydrogen doping, the transition to zero carbon fuel.
Carbon Capture and Storage (CCUS): Reduce the carbon intensity of existing power plants.
Intelligence and Digital Twin: Improve operational efficiency and optimize power generation strategies.
Miniaturization and distributed applications: Microcombustion engines provide reliable backup power in scenarios such as data centers, hospitals and more.
Typical Case: Current State of Development in China
Installation scale: By the end of 2023, China’s natural gas power generation will be installed at about 120 million kilowatts, accounting for 4.5% of the total installed capacity.
Regional concentration: mainly distributed in the long triangle, pearl triangle and other economically developed, relatively abundant gas resources.
Policy-driven: The 14th Five-Year Plan explicitly promotes the use of natural gas power generation in peak areas and introduces gas and electricity subsidy policies in many places.
The challenge is highlighted: high gas prices cause some units to use less hours and need to divert costs through market mechanism reform.
Summary
With its core advantages of being clean, low-carbon, flexible and efficient, natural gas power generation plays an irreplaceable role in the energy transition period, especially as the “best partner” for renewable energy. However, its development is constrained by fuel costs, climate target constraints and market mechanisms.
Key insights: Gas power generation is not the ultimate solution, but a key springboard for the energy system’s transition from “high carbon” to “zero carbon”. Its value lies not in scale, but in strategically supporting the renewable energy revolution.
