Market opportunities for gas sensors in the era of carbon neutrality

　　Mankind is increasingly aware that human activities have produced irreversible impacts on climate and ecological environment, which will affect mankind itself. Throughout the world, the current situation of global carbon emissions is that power generation consumption is a large source of carbon dioxide. The secondary sources of CO2 in developed economies (USA and EU) are transportation and building consumption, while the secondary sources in developing economies (medium and India) are mainly industrial combustion.

　Since the government Work Report of 2021 listed "solid efforts to achieve carbon peak and carbon neutrality" as one of the priorities, how to achieve the goal of "carbon neutrality" has also become a hot topic in the sensor circle.

　　What is carbon neutral? Carbon is what we call carbon dioxide, which is the balance between positive and negative. That is to say, through energy conservation, emission reduction, energy substitution and other ways, so that the emitted carbon dioxide is recycled, to achieve zero carbon dioxide emissions.

　　Everything can be carbon neutral, and gas sensors are essential for environmental monitoring

　　Carbon dioxide content is an important indicator to measure air quality, carbon neutrality is to confirm carbon emissions, carbon dioxide sensors are essential. According to the different principles, carbon dioxide sensors can be mainly divided into solid electrolyte type, capacitor type, optical fiber, infrared absorption and other types. Infrared carbon dioxide sensor is the mainstream type at present.

　　Infrared carbon dioxide sensor is to obtain the content of carbon dioxide in the measured gas through the absorption effect of carbon dioxide on the infrared radiation of a specific band and the strength of radiation energy measured. Infrared carbon dioxide sensor has higher accuracy, better stability, can be widely used in central air conditioning, fresh air system and air quality detection equipment.

　　The carbon neutral field monitors not only carbon dioxide concentrations, but also other greenhouse gases such as methane (CH4), nitrous oxide, hydrofluorocarbons, and sulfur hexafluoride. At present, this kind of gas sensor mining network is complete.

　　In addition, the realization of the goal of carbon neutrality requires the control of carbon emissions in many parts of the industrial chain. This involves other kinds of gas sensors, and with increasingly high emission standards, more requirements will be put forward for these gas sensors.

　　Market opportunity for gas sensors under carbon neutrality

　　According to relevant reports, in the global market, the demand for gas sensor applications is growing constantly, and will maintain a compound annual growth rate of 7.3% from 2016 to 2021. By 2021, the global gas sensor market scale will reach $920 million. According to the report, by 2026, the shipment of gas sensors will reach 80 million, and the market is valued at more than $2 billion, with a compound growth rate of about 7%.

　　In the context of carbon neutrality, many instrument companies from sensors to responsive instruments and data analysis systems have done the corresponding layout, and some have been applied in the current environmental field. Thanks to the first-mover advantage, market demand scale and complete industrial chain, domestic sensor enterprises are in a favorable position in terms of laser dust sensor technology level and industry scale, and continue to increase their market share by combining strategies in dust, CO2 and ⅤoC gas sensor supporting fields. Currently, in the field of indoor air quality monitoring, carbon dioxide sensors have been widely used, or become a representative of the next growth point.
