reference news network reported on october 2according to the "nihon keizai shimbun" report on october 1, in order to achieve the goal of curbing climate warming, countries are focusing on carbon capture, utilization and storage (ccus) technology (this technology can directly reduce carbon dioxide emissions, vividly known as "carbon catcher" technology - this website's note) launches research and development competition. this technology recovers and stores carbon dioxide contained in exhaust gases from factories and power generation facilities, or reuses it.

with the support of relevant experts from mitsui & co.'s strategic research institute, "the nikkei" used the analytical tools of lexisnexis, an intellectual property information service provider, to analyze the global valid patents related to ccus technology since 2000. the results show that as of early february 2024, the total number of valid patents has reached 22,370, which has increased to 2.3 times that of the end of 2013.

the analysis shows that in the comprehensive competitiveness index score that takes into account quantity and quality, the united states ranks first, followed by china, and japan ranks third.

in the ranking of enterprises and institutions, the chinese academy of sciences tops the list and has strong technical strength in methane conversion. ranked second is saudi aramco, which has strong technical advantages in carbon dioxide separation and chemical product raw material conversion. japan's mitsubishi heavy industries ranks third.

in the future, it is expected that the ability to transform relevant technological achievements will determine international competitiveness. (compiled/liu lin)
