据烃加工新闻7月13日消息称，壳牌宣布了一项在埃德蒙顿附近的斯科特福德综合体建设大规模碳捕获和封存 (CCS) 项目的提议。这将是将斯科特福德转变为壳牌全球五大能源和化学品园区之一的关键一步，为客户提供未来的低碳燃料和产品，如氢。
拟议中的北极星CCS项目是壳牌在斯科特福德勘探的一系列低碳机遇中最大的一个，将从壳牌拥有的斯科特福德炼油厂和化工厂捕获二氧化碳。初始阶段预计将在 10 年中期左右开始运营，这取决于壳牌预计在 2023 年做出的最终投资决定。“北极星”项目在整个项目期间的二氧化碳储存能力约为3亿吨。
壳牌加拿大公司总裁兼国家主席Susannah Pierce说:“壳牌正在采取大胆的行动，使我们的业务和更广泛的行业脱碳，北极星CCS项目是最新的例子。我们在斯科特福德的计划符合壳牌的目标，即到2050年成为一个净零排放的能源企业，与社会同步。我们正在创建一个世界级的站点，将为客户提供低碳燃料、产品和二氧化碳存储。北极星还将为壳牌到2035年每年增加2500万吨CCS产能的目标做出重大贡献。”
北极星CCS项目是在斯科特福德的Quest CCS设施取得成功之后进行的，该设施在6年的运行中已经捕获并安全储存了超过600万吨的二氧化碳。最近，壳牌也就挪威的北极光CCS项目做出了最终投资决定，并参与了荷兰的Porthos CCS项目。
北极星CCS项目的初始阶段将每年从斯科特福德炼油厂和化工厂捕获并储存大约75万吨二氧化碳。它将减少壳牌炼油厂直接和间接排放的40%和化工厂的30%。它还将创造多达2000个工作岗位。
北极星CCS项目的第二阶段包括在艾伯塔省建立一个二氧化碳储存中心，进一步使壳牌的设施脱碳，并代表第三方工业来源作为一个值得信赖和可靠的二氧化碳储存运营商来储存排放。
一旦完全建成，北极星将为埃德蒙顿地区成为加拿大第一个氢中心做出贡献。在北极星项目的初始阶段，从炼油厂的制氢厂捕获的二氧化碳将生产用于炼油过程的蓝氢，并有可能在未来阶段大规模生产蓝氢。壳牌还在斯科特福德开发更多的蓝氢和绿氢，利用阿尔伯塔丰富的天然气和可再生能源。

Shell proposes large-scale CCS facility in Alberta
Shell announced a proposal to build a large-scale carbon capture and storage (CCS) project at its Scotford Complex near Edmonton. This would be a key step in transforming Scotford into align="justify"> The proposed Polaris CCS project, the largest in a series of low-carbon opportunities Shell is exploring at Scotford, would capture carbon dioxide (CO2) from the Shell-owned Scotford refinery and chemicals plant. The initial phase is expected to start operations around the middle of the decade, subject to a final investment decision by Shell expected in 2023. Polaris would have storage capacity of about 300 million tonnes of CO2 over the life of the project.
“Shell is making bold moves to decarbonize our operations, and wider industry, and the Polaris CCS project is the latest example,” said Susannah Pierce, Shell Canada President and Country Chair. “Our plans for Scotford are in line with Shell’s target to become a net-zero emissions energy business by 2050, in step with society. We are creating a world-class site that will provide customers with lower-carbon fuels, products and CO2 storage. Polaris would also make a significant contribution to Shell’s aim to have access to an additional 25 million tonnes a year of CCS capacity by 2035.”
The Polaris CCS project follows the success of the Quest CCS facility at Scotford, which has captured and safely stored more than six million tonnes of CO2 in its six years of operation. Recently, Shell has also taken a final investment decision align="justify"> The initial phase of the Polaris CCS project would capture and store approximately 750,000 tonnes a year of CO2 from the Scotford refinery and chemicals plant. It would reduce Shell’s direct and indirect emissions (Scopes 1 and 2) by up to 40% from the refinery and by up to 30% from the chemicals plant. It would also create up to 2,000 jobs.
The second phase of the Polaris CCS project involves the creation of a CO2 storage hub in Alberta, further decarbonizing Shell’s facilities and storing emissions align="justify"> once fully built, Polaris would contribute to the Edmonton region becoming Canada’s first hydrogen hub. In the initial phase of Polaris, CO2 captured from the refinery’s hydrogen plants would produce blue hydrogen for use in the refining process, with the potential for large-scale blue hydrogen production in future phases. Shell is also exploring the development of additional volumes of blue and green hydrogen at Scotford that leverage Alberta’s abundance of natural gas and availability of renewable sources of power.
