埃克森美孚为路易斯安那州碳捕获项目与EnLink签署了协议

据管道&天然气杂志网10月13日报道，CF产业公司与埃克森美孚公司达成了一项规模最大的商业协议，该公司将从其位于路易斯安那州的生产基地每年捕获并永久储存多达200万吨的二氧化碳排放。该项目计划于2025年初启动，支持路易斯安那州在2050年实现二氧化碳净零排放的目标。

正如之前宣布的那样，CF产业公司正在投资2亿美元，在其路易斯安那州唐纳森维尔（Donaldsonville，Louisiana）的设施中建造一个碳脱水和压缩装置，以便能够运输和储存捕获。然后，埃克森美孚将把捕获的二氧化碳运输并永久储存在其在Vermilion Parish拥有的安全地质储存库中。

作为该项目的一部分，埃克森美孚已与Enlink Midstream签署协议，使用Enlink的运输网络将碳输送至永久地质封存区。每年捕获的200万吨排放量将相当于用电动汽车取代大约70万辆汽油动力汽车。

Enlink首席执行官Jesse Arenivas表示，Enlink已经在路易斯安那州的地下铺设了超过4000英里的管道系统。利用这个庞大的网络，能够提供最及时、最具成本效益的二氧化碳运输解决方案，并显著降低对环境的影响。正因为如此，Enlink在路易斯安那州的密西西比河走廊是工业活动的中心，对经济非常重要，它是一个独特的定位，成为首选的二氧化碳运输提供商。公司期待着与埃克森美孚公司合作，帮助CF产业公司和路易斯安那州实现脱碳目标。

CF产业公司预计每年销售高达170万吨蓝氨。当二氧化碳排放在释放到空气中之前就被捕获时，化学过程被认为是“蓝色”的，这使该过程更具碳中性。蓝氨作为难以减少的工业的脱碳能源，其氢含量和作为燃料本身的需求预计将显著增长，因为氨的组成部分——氮和氢——在燃烧时不排放碳。

埃克森美孚低碳解决方案公司正致力于将低排放技术推向市场，使其能够进入美国和国际上难以脱碳的行业。其将碳捕获和储存工作重点放在点源排放上，这是一个从工业活动中捕获碳的过程，否则会释放到大气中。二氧化碳一旦被捕获，就会被注入到地下深处的地质构造中，以便安全、可靠和永久地储存。在美国，这些储存工作由州和联邦机构监管。

碳捕获和封存是一项安全的、经过验证的技术，可以使一些排放最高的行业实现有意义的减排。这些行业包括制造业、发电、炼油、石化、钢铁和水泥生产。在有效的政府政策到位的情况下，广泛部署商业规模的碳捕获和封存项目可以创造一个新的行业，从而创造就业机会和经济增长。

埃克森美孚低碳解决方案总裁Dan Ammann表示，这一具有里程碑意义的项目代表了在全球经济脱碳之旅上取得的大规模、真实的进展。埃克森美孚正在为减少二氧化碳排放提供关键的、可扩展的解决方案，也准备向路易斯安那州和世界各地的其他大型工业客户提供同样的服务。

Exxon Mobil Taps Enlink’s Pipeline Network for Louisiana Carbon Capture Project

CF Industries has entered into the largest-of-its-kind commercial agreement with Exxon Mobil to capture and permanently store up to 2 million metric tons of CO2 emissions annually from its manufacturing complex in Louisiana. Start-up for the project is scheduled for early 2025 and supports Louisiana’s objective of net zero CO2 emissions by 2050.

As previously announced, CF Industries is investing $200 million to build a CO2 dehydration and compression unit at its Donaldsonville, Louisiana, facility to enable captured CO2 to be transported and stored. Exxon Mobil will then transport and permanently store the captured CO2 in secure geologic storage it owns in Vermilion Parish.

As part of the project, Exxon Mobil has signed an agreement with Enlink Midstream to use Enlink’s transportation network to deliver CO2 to permanent geologic storage. The 2 million metric tons of emissions captured annually will be equivalent to replacing approximately 700,000 gasoline-powered cars with electric vehicles.

“Enlink has a system of over 4,000 miles of pipeline already in the ground in Louisiana,” Jesse Arenivas, CEO of Enlink, said. “Utilizing this extensive network enables us to provide the most timely and cost-effective solution to CO2 transportation, with a significantly lower environmental impact. Because of this, Enlink is uniquely positioned to be the CO2 transportation provider of choice in Louisiana's Mississippi River corridor, which is a hub of industrial activity that is important to our economy. We look forward to working with Exxon Mobil to help CF Industries and the State of Louisiana reach their decarbonization goals.”

CF Industries expects to market up to 1.7 million metric tons of blue ammonia annually. A chemical process is considered “blue” when CO2 emissions are captured before their release into the air, making the process more carbon-neutral. Demand for blue ammonia is expected to grow significantly as a decarbonized energy source for hard-to-abate industries, both for its hydrogen content and as a fuel itself, because ammonia’s components – nitrogen and hydrogen – do not emit carbon when combusted.

Exxon Mobil Low Carbon Solutions is working to bring lower-emission technologies to market, making them accessible to hard-to-decarbonize industries in the United States and internationally. It is focusing its carbon capture and storage efforts on point-source emissions, the process of capturing CO2 from industrial activity that would otherwise be released into the atmosphere. once captured, the CO2 is injected into deep, underground geologic formations for safe, secure and permanent storage. In the United States, these storage efforts are regulated by state and federal agencies.

Carbon capture and storage is a safe, proven technology that can enable some of the highest-emitting sectors to meaningfully reduce their emissions. These industries include manufacturing, power generation, refining, petrochemical, steel, and cement operations. With effective government policies in place, broad deployment of commercial-scale carbon capture and storage projects could create a new industry, resulting in job creation and economic growth.

“This landmark project represents large-scale, real-world progress on the journey to decarbonize the global economy,” Dan Ammann, president of Exxon Mobil Low Carbon Solutions, said. “Exxon Mobil is providing a critical and scalable solution to reduce CO2 emissions, and we’re ready to offer the same service to other large industrial customers in the state of Louisiana and around the world. We’re encouraged by the momentum we see building for projects of this kind, thanks to supportive policies such as the Inflation Reduction Act.”
