(彭博社)石油巨头西方石油公司与微软公司达成了创纪录的碳去除协议,这家软件巨头正在努力减少其不断扩大的排放量。

西方石油公司正通过其子公司 1PointFive 建立碳捕获投资组合,计划建造一批直接从空气中吸收二氧化碳的工厂。微软周二同意从该公司位于德克萨斯州的 Stratos 工厂购买 50 万公吨碳信用额,该工厂预计将于明年投产。

这笔交易是所谓的直接空气捕获(DAC)产生的信用额度的最大一笔购买,这巩固了西方石油在扩大碳捕获技术规模和货币化竞争中的地位。对于微软来说,这类协议对于解决日益增长的碳足迹至关重要,因为微软进军人工智能领域已导致排放量激增。

然而,DAC 使用巨型风扇从大气中吸出二氧化碳,成本高昂,耗能大,而且尚未在工业规模上得到验证。世界上最大的 DAC 工厂由 Climeworks AG 运营,设计每年可吸收 36,000 吨二氧化碳,远远达不到阻止全球变暖最严重影响所需的数十亿吨二氧化碳。

但如果 DAC 能够像承诺的那样发挥作用,它不仅有助于限制全球变暖,还可以帮助提高自愿碳市场的质量。

微软是蓬勃发展的碳去除行业的早期支持者,并与斯德哥尔摩 Exergi 和 Orsted A/S 签署了重要协议,购买发电厂产生的二氧化碳排放额。

去年,微软还与 Heirloom Carbon Technologies Inc. 签署了一项 31.5 万吨碳去除协议。据行业追踪机构 cdr.fyi 称,微软是迄今为止最大的碳去除额度投资者,其投资组合中已购买了超过 800 万吨碳去除额度。

尽管微软的目标是到 2030 年实现碳负排放,但其去年的排放量比 2020 年高出约 30%,部分原因是能源密集型人工智能数据中心。微软总裁布拉德·史密斯 (Brad Smith) 最近表示,如果微软的目标是实现脱碳,那么月球距离“是 2020 年的五倍多”。

拜登总统的政府对 DAC 进行了巨额投资,承诺斥资 35 亿美元建立区域中心,旨在每年清除、捕获和储存 18 亿吨废物,到本世纪中叶实现净零排放。

1PointFive 和 Climeworks 是能源部在墨西哥湾沿岸斥资 12 亿美元建设 DAC 枢纽项目的两家入选公司。然而,这两家公司的使命截然不同。Occidental 的部分动机是希望利用捕获的碳来生产更多石油。

西方石油公司首席执行官维姬·霍卢布 (Vicki Hollub) 称 DAC 是生产“零排放石油”的一种方式,并表示从其设施捕获的部分二氧化碳将用于提高石油采收率,即向油井注入二氧化碳以开采更多石油。

耗资 10 亿美元的 Stratos 工厂预计将于 2025 年中期投入运营,该工厂还向亚马逊公司、Shopify 公司和空中客车公司出售了信用额度。西方石油希望在未来 10 年内再建造 99 座类似的工厂。

在二月份的一次投资者演示中,该公司预计其将能够以每吨 125 至 200 美元的成本大规模捕获碳,但考虑到该过程的能源强度,一些 DAC 专家认为这一估算只是“幻想”。

但据彭博新能源财经报道,如果西方石油成功的话,到 2050 年,这家价值 540 亿美元的公司的市值可能达到 1500 亿美元。

(Bloomberg) – Oil giant Occidental Petroleum Corp. clinched a record carbon removal deal with Microsoft Corp. amid the software titan’s push to reduce its expanding emissions.

Occidental, which is building a carbon-capture portfolio through its subsidiary 1PointFive, plans to build a fleet of plants that suck carbon dioxide directly from the air. Microsoft on Tuesday agreed to buy 500,000 metric tons of credits from the company’s Stratos plant in Texas, which is expected to start up next year.

The deal marks the single largest purchase of credits generated by so-called direct air capture, or DAC — bolstering Occidental’s position in the race to scale and monetize carbon capture technology. For Microsoft, whose push into artificial intelligence has triggered a spike in emissions, such agreements are central to addressing a growing carbon footprint.

Yet DAC, which uses giant fans to suck carbon dioxide out of the atmosphere, is expensive, energy-intensive and not yet proven at industrial scale. The world’s largest DAC plant, operated by Climeworks AG, is designed to corral 36,000 tons of CO2 annually, far from the billions of tons required to stave off the worst effects of global warming.

But if DAC works as promised, it will not only help to limit global warming but could also help improve the quality of the voluntary carbon market.

Microsoft was an early supporter of the burgeoning carbon removal industry, signing major deals with Stockholm Exergi and Orsted A/S to buy CO2 credits generated at power plants.

It also inked a deal last year with Heirloom Carbon Technologies Inc. for 315,000 tons of carbon removal. Microsoft is by far the largest investor in carbon removal credits to date, having purchased more than 8 million tons across its portfolio, according to the industry tracker cdr.fyi.

While Microsoft aims to be carbon negative by 2030, its emissions last year were about 30% higher than in 2020 in part due to energy-intensive AI data centers. Microsoft President Brad Smith recently said that if Microsoft is shooting for the moon on decarbonization, the moon is “more than five times as far away as it was in 2020.

President Joe Biden’s administration has invested big in DAC, promising to spend $3.5 billion on regional hubs aimed at removing, capturing and storing 1.8 billion tons annually to achieve net-zero emissions by mid-century.

1PointFive and Climeworks were two of the companies selected to be part of the Energy Department’s $1.2 billion DAC hubs project on the Gulf Coast. Yet the companies have very different missions. Occidental is motivated in part by the promise of using captured carbon to produce more oil.

Occidental Chief Executive Officer Vicki Hollub has called DAC a way to produce “net-zero oil,” and said some of the CO2 captured from its facilities will be used for enhanced oil recovery, which involves injecting CO2 into oil wells to extract more oil.

The $1 billion Stratos plant, which is expected to start operations in mid-2025, also has sold credits to Amazon.com Inc., Shopify Inc. and Airbus SE. Occidental hopes to build 99 more like it over the next 10 years.

In a February investor presentation, the company projected that it will be able to capture carbon at scale for $125 to $200 per ton, an estimate that some DAC experts view as “a fantasy” given the energy-intensity of the process.

But if Occidental succeeds, the $54 billion company could be worth $150 billion by 2050, according to BloombergNEF.
