Agricultural methane emission reduction can learn from the energy industry

Word：[Big][Middle][Small] 2023/7/20 Viewed：

As an important energy gas, methane is the second largest greenhouse gas after carbon dioxide. From the perspective of emission sources, methane emissions from the global energy sector account for about 40% of the total methane emissions, while methane emissions from agriculture and animal husbandry also account for 40%. However, society has higher requirements for emission reduction in the energy and chemical industry, and slightly lower requirements for methane in agriculture and animal husbandry. This is partly due to the stereotype that industry should be more responsible for pollution, but also because it is indeed easier to reduce pollutant emissions in the industrial sector than in the agricultural sector. The author believes that the energy and chemical industry is a pioneer in methane emission reduction, and its accumulated experience and developed technology are entirely likely to become a boost to agricultural methane emission reduction.

In recent years, methane emission reduction in the energy sector has attracted much attention. Some industry organizations and large energy companies in Europe and the United States have also established cooperation frameworks to promote global methane emission reduction. The United States and Europe have successively launched methane emission reduction strategies or action plans, and jointly initiated the signing of the "Global Methane Pledge" during the 26th United Nations Climate Change Conference with 103 countries. In this context, large energy and chemical companies have proposed methane emission reduction targets and adopted a series of methane emission reduction measures in order to create a green corporate image. Emission reduction goals are not difficult to establish, but how to monitor and control methane emissions in actual production is another matter of knowledge.

As a pioneer in reducing methane emissions, the energy and chemical industry has developed some technologies. For example, in terms of monitoring methane emissions, oil and gas companies that have done a good job include Shell, Total Energy, and British Petroleum (BP). Shell uses drones, planes equipped with optical gas imaging cameras, and satellites to detect methane leaks. Total Energy uses ground-based infrared cameras, drones, and satellites to detect methane leaks. BP adopts a hierarchical monitoring method. For projects with high security and large leakage, the most accurate on-site continuous monitoring method is adopted. If the precision is right, these techniques can also be applied in areas such as crop fields and pastures.

In addition, another emission reduction experience in the energy and chemical industry is to establish industry alliances, formulate unified standards, promote industry emission reduction actions, and exchange technologies. For example, companies such as BP, Eni, and Total Energy have launched the Oil and Gas Methane Partnership (OGMP), which conducts unified methane emission accounting and promotes emission reduction technologies based on the technical guidance documents provided by the organization. Shell and other international oil and gas companies, international agencies, non-governmental organizations and academia jointly launched the Methane Emissions Guiding Principles (MGP) Partnership and released a series of best practice guidelines for methane emission reductions. The author believes that these experiences are somewhat difficult for small-scale agricultural producers, but they can be used for reference by large-scale agricultural and animal husbandry enterprises.

JIN DUN CHEMICAL has built a special (meth) acrylic monomer manufacturing base in ZHEJIANG province. This makes sure the stable supply of HEMA, HPMA, HEA, HPA, GMA with high level quality. Our special acrylate monomers are widely used for thermosetting acrylic resins, crosslinkable emulsion polymers, acrylate anaerobic adhesive, two-component acrylate adhesive, solvent acrylate adhesive, emulsion acrylate adhesive, paper finishing agent and painting acrylic resins in adhesive.We have also developed the new and special (meth) acrylic monomers and derivatives. Such as the fluorinated acrylate monomers, It can be widely used in coating leveling agent, paints, inks, photosensitive resins, optical materials, fiber treatment, modifier for plastic or rubber field. We are aiming to be the top supplier in the field of special acrylate monomers, to share our rich experience with better quality products and professional service.
