在2060年碳中和目标的要求下,碳捕集、利用与封存技术将扮演重要角色。目前碳捕集、利用与封存技术在中国尚处于工业示范阶段,面临技术成熟度不足、经济成本高、融资渠道单一、应用领域有限、盈利能力差等障碍,迫切需要建立合理的商业模式以推进技术部署。本文梳理了国际上现有的碳捕集、利用与封存商业化项目和相关支持政策,基于商业模式画布的研究框架,分析了碳捕集、利用与封存商业化部署的现状、特点与障碍,并在此基础上提出了相应建议,包括加强技术研发、完善政策体系、布局基础设施和促进集群建设。 相似文献

碳捕集与封存是我国石油行业的重要转型发展机遇,重点研究CCS两个较为成熟的主要方向对石油行业的机遇,一是在地质封存CO2同时提高石油天然气采收率,即CCS-EOR,另一个是利用盐水层(也称咸水层)或其它地下空间对CO2进行封存。文章论述了CCS对于温室气体减排的重要作用,CCS作为我国石油行业转型发展机遇的分析。CCS是我国石油行业的重要转型发展机遇,国内石油公司应对CCS进行重点研究和适度发展。 相似文献

对于能源密集型行业和难减排工业来说,二氧化碳捕集、地质利用和封存(CCUS)是缓解气候变化不可或缺的关键技术工具,但同时也会带来相应的生态环境问题。目前我国针对CCUS的环境法律法规、生态环境管理技术规范、CO2监测标准、环境风险管控、核算办法和交易路径等要求仍然相对滞后。本文梳理了国内外CCUS的发展现状和趋势以及环境管理方面的不足。建议在CCUS全过程环境管理的联动衔接、CCUS的环境监测标准规范、基于封存CO2运移和运输管道泄漏情景的源强定量风险评价模型、减污降碳协同控制、减排量核算方法学及碳交易途径等方面进一步出台科学化管控政策,优化和规范我国CCUS行业的环境管理流程,发挥CCUS项目最大的生态环境和社会经济价值。 相似文献

Trametes versicolor decolorized 2000 mg L(-1) of the mono-azo substituted naphthalenic dye Amaranth with no dye sorption observed visually. The changes in the toxicity were assessed over a period of 30 d for the dye-treated viable culture, control (no dye added), and a boiled culture treated with dye, using the Microtox Acute Toxicity assay. Before dye addition, the culture filtrate had some toxicity, which increased after the dye addition. The toxicity of the dye-treated culture decreased during the treatment. The loss of toxicity occurred at the same time, with the loss of color suggesting that detoxification is associated with decoloration. The change in pH was due to natural metabolic processes and had a small effect on detoxification. Because the toxicity of the treatment was similar to that of the control at the end of the treatment, the effluent seems to be safe for release into the environment, potentially rendering this treatment suitable for industrial application. 相似文献

The increase in the number of tourists visiting a coast is desired by most of the countries for economic reasons. However, this increase in tourism may cause pollution of the sea. This can be only avoided by proper planning and by predicting the carrying capacity of the coast in terms of sea pollution. This is especially important for developing countries where part of the wastewater is discharged without any treatment into the sea.In the present study the beaches were classified according to their use — and consequently the amount of waste discharged into the sea — into four groups: (1) coasts that are used only for swimming and recreational purposes; (2) coasts used simultaneously for dwelling, swimming, and recreational purposes; (3) coasts along which only dwellings exist; and (4) natural and man-made harbors, i.e., coasts used as shelters. During the survey,40,320 observations were made between December 1985 and February 1988 to determine the effect of the number of tourists on seawater quality. The results obtained were analyzed by a multilinear regression program to obtain an empirical equation giving the extent of the sea pollution in terms of coliform concentration as a function of population density and some other environmental factors.The equations derived in this study enable the determination of the carrying capacity of a beach in terms of pollution as well as the expected degree of pollution corresponding to a given population density. Furthermore, it allows the prediction of the extra carrying capacity that can be obtained by improving the waste-disposal conditions. 相似文献
