减排增效价值显著 近日，在中国化工学会化工碳中和技术专业委员会第二届学术年会"碳捕集与资源转化"专题论坛上，与 会专家一致认为，当前，碳捕集技术已在部分化工场景中实现小范围、试点性应用，但其规模化、商业 化推广仍面临多重瓶颈，未来将从材料与工艺创新、节能与效能提升和产业协同三个方向发力迈向规模 化应用。 产业链协同不足同样制约着发展速度。大连理工大学陈绍云教授从产业实践角度指出："我们开发的二 氧化碳制甲醇技术，面临国内总量不足、难以满足规模化应用需求的困境，这需要上下游产业链的紧密 配合与协同布局。"而武汉工程大学易群教授团队的研究也揭示了行业共性瓶颈。他指出，降低再生能 耗、抑制吸收剂损耗、简化再生工艺是二氧化碳捕集技术发展的关键问题。具体来看，工业烟气二氧化 碳浓度低、湿度高，导致捕集过程能耗高且吸附剂易受水分干扰，进一步加剧了碳捕集资源化的产业化 难度。 规模化应用未来可期 针对技术经济性不足、产业链协同弱等瓶颈，与会专家提出系统化破解路径，同时预判碳捕集技术系统 化创新将催生多个新兴赛道。 在材料与工艺创新上，常州大学钟璟教授提出，应面向工业分离需求，以分子模拟与机器学习为基础构 建材料设计方法，聚 ...

Group 1 - The United States has become the global center of the anti-ESG movement, with a significant increase in anti-ESG legislation proposed across 40 states from 2021 to 2024, totaling 370 bills [1][2] - The passage rate of anti-ESG bills in 2024 is notably higher than in previous years, indicating improved legislative drafting capabilities among proponents [1][2] - The Trump administration has further fueled the anti-ESG sentiment by revoking climate action policies and signing an executive order banning ESG investments [2] Group 2 - Since Trump's re-election, an estimated $28 billion worth of wind, solar, electric vehicle, and battery projects have been delayed or canceled, affecting approximately 19,000 jobs [2] - International oil giants are reducing their clean energy investments, with ExxonMobil announcing plans to abandon a major low-carbon hydrogen project unless federal tax incentives are provided [3] - BP has adopted a more conservative decarbonization strategy, focusing on higher-margin hydrogen, biofuels, and offshore wind, while abandoning its hydrogen development goals [3][4] Group 3 - Shell has canceled plans for a low-carbon hydrogen plant in Norway, citing insufficient demand, a sentiment echoed by Equinor shortly after [4]

Core Insights - A multidisciplinary research team from ETH Zurich has developed a 3D printable hydrogel that encapsulates photosynthetic cyanobacteria, creating a living material capable of self-growth in sunlight and artificial seawater while actively removing carbon dioxide from the air [1][2] - This material exhibits dual carbon sequestration capabilities, fixing carbon dioxide absorbed during cyanobacteria growth and storing it in mineral form, potentially contributing to green building and carbon capture technologies [1] - The cyanobacteria's high photosynthetic efficiency allows it to produce biomass even under low light conditions, while also altering the chemical environment to facilitate the precipitation of solid minerals, which serve as a more stable form of carbon storage compared to biomass [1] Material Characteristics - The base material is a high-water-content hydrogel that allows light and nutrients to pass through while evenly distributing the cyanobacteria [2] - The research team optimized the hydrogel's structure using 3D printing to enhance surface area, light penetration, and nutrient flow, ensuring the longevity and efficiency of the cyanobacteria [2] - Experimental results indicate that the material can capture carbon dioxide for up to 400 days, with an average carbon sequestration rate of approximately 26 milligrams per gram of material, significantly higher than many traditional biological methods [2]
