What are the advantages of gas engines as power generation equipment in distributed energy systems?

In distributed energy systems, gas engines have multiple advantages as power generation equipment, mainly reflected in the following aspects:

Efficient performance

High energy utilization efficiency: The power generation efficiency of gas engines can usually reach around 30% to 40%. Compared to some traditional large-scale centralized power generation methods, they can still maintain good efficiency performance under partial loads. At the same time, the waste heat generated by the engine can also be used for heating, cooling, etc., achieving cogeneration or combined cooling, heating, and power supply. The comprehensive energy utilization efficiency can reach up to 70% to 90%, greatly improving the value of energy utilization.

Quick response: It can quickly start and reach full load operation, usually taking only a few minutes from start to load. This feature enables it to quickly respond to changes in power demand, and can be quickly put into operation when there are large fluctuations in grid load or sudden power demands, ensuring the stability of power supply.

flexibility

Flexible installation and scale: Flexible installation can be carried out according to different energy needs and site conditions, whether in urban commercial centers, industrial parks, remote rural areas or islands, suitable application scenarios can be found. Its power coverage range is wide, ranging from tens of kilowatts to several megawatts, and the appropriate scale can be selected according to actual needs to meet the power needs of different users.

Good fuel adaptability: able to use various gas fuels, such as natural gas, biogas, coalbed methane, etc. The flexibility of this fuel allows gas engines to fully utilize the abundant local gas sources, reducing fuel costs and supply risks.

Environmental friendliness

Low emissions: Compared with traditional coal-fired power generation, gas engines burn more thoroughly and produce fewer pollutants. Its emissions of pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter are much lower than those from coal-fired power generation, which helps reduce environmental problems such as air pollution and acid rain, and meets the requirements of modern society for environmental protection.

Greenhouse gas emissions reduction: During the combustion process, the carbon dioxide emissions generated by gas engines are relatively low, which has a certain positive significance in mitigating global climate change.

reliability

Technological maturity: After long-term development and improvement, gas engine technology has become quite mature, with high operational reliability and stability. Its structure is relatively simple, maintenance costs are low, and the average time between failures is long. It can provide stable power supply for a long time and reduce power outages caused by equipment failures.

Independent operation: In a distributed energy system, multiple gas engines can form a relatively independent power generation system. Even if some engines fail, other engines can continue to operate, ensuring a certain degree of power supply and improving the reliability and fault tolerance of the entire energy system.
