Analysis on the Development Status of Shandong Negative Carbon Technology System based on Patent Analysis

Shandong's energy structure is dominated by coal, and its industrial structure is relatively high. Its carbon emission ranks first in China, accounting for about 10% of China's. At the 12th provincial Party Congress, it was proposed that "the proportion of non fossil energy consumption will increase by more than 1 percentage point per year in the next five years", which is still far from the requirements of the Party Central Committee and the State Council for provincial carbon reduction indicators [1-2]. Therefore, the task of "carbon reduction" is heavy and difficult. The realization of carbon neutrality depends on the "three points" of energy structure, energy consumption and artificial carbon fixation. At present, the per capita GDP of Shandong is at the level of 10,000 US dollars. According to the development experience of advanced countries and regions such as Europe and the United States, the carbon emissions are still in a rapid rising period with economic development. There is a great pressure to reduce carbon by adjusting the energy structure and energy consumption [3]. It is urgent to start from the point of "artificial carbon fixation", lay out technologies such as carbon capture, utilization and storage (CCUS), and do a good job in negative carbon technology reserves.
