石油设备网讯 据阿拉伯贸易网2022年12月23日休斯敦报道，埃克森美孚公司董事长兼首席执行官达伦·伍兹表示，埃克森美孚公司正计划在其位于得克萨斯州贝城的炼油和石化工厂建成第一个世界级的低碳氢生产工厂。
在那里，它每天将从天然气中生产多达10亿立方英尺的氢气，其中约95%的二氧化碳被捕获，然后安全储存在地下。
伍兹说，这个项目将在两个方面改变游戏规则。首先，使用氢气为埃克森美孚公司在贝城的烯烃工厂提供燃料，与目前的运营相比，可以减少高达30%的二氧化碳排放。这个项目将支持埃克森美孚公司在2050年前在其运营资产上实现温室气体净零排放(范围1和范围2)的雄心。
世界上最大的碳捕获和储存项目
其次，这个计划中包含的碳捕获和储存项目将是世界上最大的项目之一，每年能够储存多达1000万吨二氧化碳，相当于200多万辆汽车的排放量。它可以使埃克森美孚公司目前每年900万吨的碳捕获和储存能力翻一番，这在行业中处于领先地位。
这个碳捕获和储存设施将标志着埃克森美孚公司对其去年宣布的休斯敦碳捕获中心概念的初步贡献。伍兹表示，到2040年前，这一概念将发展成为一项跨行业的努力，从休斯敦地区的发电厂、炼油厂和石化设施，包括埃克森美孚公司的贝城基地，每年捕获和储存高达1亿吨的二氧化碳。
减少埃克森美孚公司在贝城的碳排放，可以降低埃克森美孚公司在那里生产的产品的碳足迹，包括用于从医疗设备到手机和电动汽车等各种产品的现代聚合物，从而使其客户受益。埃克森美孚公司还计划将这种低碳氢气提供给休斯敦地区的其他工业设施，以帮助他们减少碳排放。
“所以，你可以明白为什么这个项目会改变游戏规则。这将使我们能够减少我们在贝城的温室气体排放，帮助我们的客户减少排放，并为地区工业提供额外的解决方案。我们预计在两到三年内做出最终投资决定，这将取决于政府的支持政策、必要的监管许可和市场条件。”伍兹如是说。
氢气需求有望增长
对于重工业等难以脱碳的行业来说，氢气在减少温室气体排放方面尤为重要。国际能源署将氢气和氢基燃料满足全球10%的能源需求作为其“2050年净零”方案的一部分。与碳捕获和储存一起，这对于实现社会温室气体净零排放目标至关重要。
伍兹说，政府可以通过实施支持性政策，例如碳定价，来加快对这些技术的投资，这有助于降低成本和建立新市场。
“没有一项技术能够在维持当今能源系统所支持的生活水平的同时，让世界实现净零排放。专家们一致认为，我们需要一系列解决方案，包括氢和碳的捕获和储存。埃克森美孚公司在这两方面都有深厚的专业知识，并期待着帮助推进这些技术和其他技术，以创造可持续的解决方案，提高生活质量，满足社会不断变化的需求。”

ExxonMobil plans mega green hydrogen plant at Baytown
ExxonMobil is planning its first world-scale plant for the production of low-carbon hydrogen at its refining and petrochemical facility at Baytown, Texas, said Darren Woods, ExxonMobil’s Chairman and CEO.
There, it would produce up to 1 billion cubic feet per day of hydrogen made from natural gas, with approximately 95% of the associated CO2 captured and then safely stored underground.
This project would be a game changer – in two ways, he said.
First, using hydrogen to fuel Exxon’s olefins plant at Baytown could reduce site-wide CO2 emissions by up to 30% compared to current operations. The project would support ExxonMobil’s ambition to achieve net-zero greenhouse gas emissions (Scopes 1 and 2) across its operated assets by 2050.
World's largest
Second, the carbon capture and storage project included in this plan would be one of the world’s largest, capable of storing up to 10 million metric tonnes of CO2 per year – equal to the emissions from more than 2 million cars. It could double the company’s current carbon capture and storage capacity of 9 million metric tonnes per year, which leads industry.
This carbon capture and storage facility would mark ExxonMobil’s initial contribution to the Houston carbon capture hub concept it announced last year. Today, this concept has evolved into a cross-industry effort to capture and store up to 100 million metric tonnes of CO2 per year by 2040 from Houston-area power plants, refineries and petrochemical facilities, including Exxon’s Baytown site, said Woods.
Reducing the company’s emissions at Baytown would benefit its customers by lowering the carbon footprint of the products it makes there, including the modern polymers found in everything from medical equipment to cell phones and electric cars. Exxon also plans to make this low-carbon hydrogen available to other Houston-area industrial facilities, to help them reduce their emissions.
“So, you can see why this project would be a game changer. It would enable us to reduce our greenhouse gas emissions at Baytown, help our customers reduce their emissions, and provide additional solutions to area industries. We expect to make a final investment decision in two or three years, subject to supportive government policy, necessary regulatory permits and market conditions,” he said.
Hydrogen poised for growth
Hydrogen is especially important in reducing greenhouse gas emissions for the hard-to-decarbonise sectors such as heavy industry. The International Energy Agency sees hydrogen and hydrogen-based fuels meeting 10% of global energy needs as part of its “Net Zero by 2050” scenario. Along with carbon capture and storage, it will be critical to achieving societal net-zero greenhouse gas emissions goals.
Governments can accelerate investments in these technologies by putting in place supportive policies, such as a price on carbon, which can help reduce costs and build new markets, he said.
“No single technology will get the world to net zero while maintaining the living standards today’s energy system supports. Experts agree we’ll need a range of solutions, including hydrogen and carbon capture and storage. ExxonMobil has deep expertise in both, and looks forward to helping advance these and other technologies to create sustainable solutions that improve quality of life and meet society’s evolving needs,”
