Global warming in the last 50 years is occurring at a rate not seen since the last 2,000 years, and the instability of the climate system has increased. Almost everyone understands that carbon dioxide is a greenhouse gas that contributes to global warming, but there has been no real focus on carbon emissions in past developments, resulting in humans experiencing all kinds of climate extremes today, even dragging down other organisms.
In order to cope with the effects of climate change and to protect the ecosystem, each industry has to develop strategic objectives that are appropriate to its characteristics. But where should we start in order to significantly reduce emissions?
According to data from Our World In Data, a global development program of the University of Oxford, the largest source of carbon emissions is power and heat generation, which is responsible for 15.8 billion tons of emissions. Transportation emissions come in second place for the time being.
Heat pump technology enables the efficient use of energy through power-to-heat conversion. This type of technology conversion not only reduces the dependence on traditional combustion energy, but also enables low-carbon and environmentally friendly heating, which plays a positive role in promoting the realization of carbon emission reduction targets.
The so-called heat pump, is to consume a small amount of external energy, through the refrigerant in the heat pump cycle in the state of change, so that the heat from the low-temperature object to the high-temperature object for the transfer of mechanical devices. It is a kind of use of high level energy to make heat flow from low level heat source to high level heat source device, can be a lot of nature can not be directly utilized low level heat source (such as air, soil, industrial waste heat, solar energy, etc.) into can be utilized high level heat source, so as to achieve the purpose of saving part of the high level of energy (such as electricity, coal, gas, fuel oil, etc.).
China's construction, industry and agriculture consume a large amount of low and medium temperature heat energy, and most of it is prepared by fossil fuels, with a low percentage of renewable energy utilization. The advantage of heat pump technology lies in the integration of renewable or waste environmental heat sources to supply heat efficiently and controllably, thus replacing the need for fossil energy.
According to the country's carbon pathway, achieving carbon neutrality is a three-step process. The first stage is from 2020-2030, to achieve carbon peaking, the main tasks are to reduce the intensity of energy consumption, reduce the intensity of carbon emissions, control the consumption of coal, develop clean energy on a large scale, continue to promote the substitution of electric vehicles for traditional vehicles, advocate energy saving and guide consumer behavior. The second stage is 2030-2045, for the stage of rapid reduction of carbon emissions, the main emission reduction pathway is shifted to renewable energy as the main source of energy, large-scale completion of the replacement of electric vehicles to traditional fuel vehicles, and at the same time completing the transformation of the primary industry to reduce emissions, supplemented by carbon capture and utilization of sequestration and other technologies. The third stage is 2045-2060, a comprehensive neutralization stage, with in-depth decarbonization as the main goal, deep decarbonization of economic development, carbon dioxide capture, utilization and storage (CCUS) and bio-energy and carbon capture and storage (BECCS) and other cutting-edge technologies will usher in the commercialization and promotion stage. The first and foremost of which is to realize energy substitution, vigorously develop clean energy, replace high carbon with low carbon, clean energy instead of traditional fossil energy, control coal consumption, and guide residents to low-carbon lifestyle transition. Heat pump is an important technology to help the world realize the goal of energy transition and energy saving and carbon reduction.
In the overall reduction of carbon emissions, to achieve the goal of carbon neutrality, China's carbon emissions ranked first in the world, the task of carbon reduction is imminent, heat pump technology, energy saving and emission reduction to contribute to environmental protection!
