Photovoltaic is green energy and has the characteristics of reducing greenhouse gas carbon dioxide (CO2) emissions. This is unquestionable. However, each of the photovoltaic projects is equivalent to the emission reduction of how much CO2? First of all, we are not clear, what do we calculate the benchmark for the reduction of displacement.
The baseline calculated by the reduction should be the electricity of our daily use, not just a thermal power. According to the data released before the country, the end of 2014, 11.3% of the national electricity consumption is renewable energy (not emissions CO2).
Therefore, in our daily electricity, there is a part that does not discharge CO2. If all the full fire considers are considered, the results are large. Second, we are not clear.
Due to regional differences, the intensity of electric CO2 emissions in different regions in my country is different. That is to say, the CO2 of the processing once the electric discharge is different from Beijing and Shanghai. It is definitely a region with high technical level, renewable energy, less emissions.
Again, we are not clear, our emission reduction benchmark can both represent the uniform technology level, but also represent the most advanced technology level. The intensity of CO2 emissions in the super-critical unit is definitely low, but not all thermal power plants have the conditions for super-ultra-ultrasound. Then we are based on the level of emissions in the super-supercritical unit, or is based on the uniform level of society? It seems that it seems to be used.
At present, the general use method is to adopt a homogeneous value of a uniform technology and the most advanced technology. In view of the above three premise, the CO2 emission base of our country is calculated. 1.
According to the overturizing surface of the power grid, the national division is divided into six major regions. Each area is calculated based on total emissions (coal, oil, gas) and total power generation (thermal electricity, hydropower and other renewable energy). Moreover, this emission reduction factor varies with the annual emissions and data changes in power generation.
2, emission factor EF = 75% EFOM + 25% EFBM, EFOM represents the uniform level of society, EFBM represents the most advanced technology. According to the annual reduction data released by the climate division of the National Development and Reform Commission, the sorted emission reduction factor is shown in the table below. Remarks: Due to the lag of data, each year's emission reduction factor is calculated from 3 to 5 years before the year.
For example, the emission reduction factor in 2012 is to use the data from 2008 to 2010 to calculate. Through Tables 1 and 2, we can consult every province, a year's emission reduction factor. For example, in 2013, the photovoltaic project in Zhejiang Province has a 1MWH electricity to reduce 0.
7856 tons of CO2; the photovoltaic project in Jilin Province is 1MWH electricity to reduce 0.9869 tons of CO2. In 2007, these two numbers were 0.
9234 tons of CO2 and 1.1461 tons of CO2. Calculate the calculation method of the reduction of displacement, then look at the changes in the calendar year.
In my imagination, thermal power generation technology is constantly improving, renewable energy ratio is constantly increasing, and that emission reduction factor should be a decline in year. What about the actual situation? As can be seen from the above figure, in North China, Northeast China has increased year by year, and the value of Southern Power Grid 2014 is also higher in 2013. What is the original caused? The change in the reduction factor reflects what changes in the exit structure? The next article is decomposed by everyone.
