马士基钻井公司加入海上碳储存项目

据OE网站6月17日报道， 丹麦海上钻探公司马士基钻井公司（Maersk Drilling）加入了一个财团，其目的是为丹麦陆上设施捕获的二氧化碳开发海上储存解决方案。

马士基钻井公司周三表示，其将加入一个新的二氧化碳储存财团，该财团由丹麦英力士石油和天然气公司和Wintershall Dea组成。

该钻井公司称，该财团正在完成丹麦管辖范围内进展最快的碳捕获和储存项目之一，目标是开发丹麦近海的二氧化碳储存能力，其基于将已停用的近海油气田用于永久的二氧化碳储存。目标是开发到2030年每年可存储约350万吨CO2的海上存储能力。

作为对财团的承诺的一部分，马士基钻井公司已承诺为该项目的初期阶段提供专有技术和有限的资金。

该项目旨在建设基础设施和存储能力，以使在陆上设施中捕获的CO2能够被运输到海上，以便在海底下注入和储存。该项目的第一阶段将是一项可行性研究，以验证储层的相容性，然后进行试点以测试二氧化碳的注入。丹麦和格陵兰地质调查局（GEUS）将作为该项目的研究合作伙伴，进行专门的实验室实验和分析结果。

该公司表示，该项目旨在将捕获的二氧化碳储存在海底1700米以下的海床上。 对于陆上捕获，经过验证的碳捕获技术可以用于碳密集型设施，例如工业工厂或发电厂。

捕获的二氧化碳将被堆放在港口，并通过船舶运输到海上储存平台，该平台将再利用最初为石油和天然气生产而建造的现有基础设施。

然后，在海上平台，将使用重新定位的油气井将CO2注入海底以进行永久性封存。该财团设定了一个目标，即到2030年开发每年储存约350万吨二氧化碳的能力。这使得该项目的二氧化碳储存量相当于实现2030年丹麦减排目标所需减排量的15-20％。

其目标是2025年在丹麦近海的Nini平台上完成首口井的注入。

从长远来看，目标是到2030年提高每年存储约350万吨CO2的能力，以配合丹麦气候委员会为实现丹麦减少70％的目标所需采取的行动建议。

马士基钻井公司表示，马士基钻井公司预计，其海上钻机将被用于重新利用现有的油气井来注入二氧化碳。

马士基钻井公司首席执行官约恩·马德森（J?rnMadsen），我们很高兴能加入这项工作，通过利用海上行业的设施和能力来支持绿色转型，马士基钻井公司拥有40多年在北海钻井经验。正如丹麦政府最近在其气候计划中指出的那样，碳捕集与封存是实现2030年丹麦排放量减少70％的目标所需努力的重要组成部分。对于马士基钻井公司而言，该项目是我们创新计划的一部分， 一个建立附加能力和扩大我们钻机使用范围的有吸引力的机会。

Wintershall Dea首席技术官Hugo Dijkgraaf表示，在Wintershall Dea，我们非常确定:全球能源转型正在发生，我们打算在其中发挥决定性作用。其中一种方式就是通过这样的技术和创新项目。海上二氧化碳储存可对未来的清洁能源作出重大贡献，并有可能大大减少丹麦的二氧化碳排放。因此，我们非常感谢丹麦当局为这项重要努力提供资金的支持。

除了参与海洋碳储存财团，马士基钻井公司提醒说，其正在以多种方式努力减少与海洋钻井相关的排放。其中包括首台陆上动力钻机，以及将两台自升式钻机升级为混合动力低排放钻机。

Maersk Drilling Joins Offshore CO2 Storage Project

Danish offshore drilling company Maersk Drilling has joined a consortium whose aim is to develop an offshore storage solution for CO2 captured in Danish onshore facilities.

Maersk Drilling said Wednesday it was joining a new CO2 storage consortium formed by INEOS Oil & Gas Denmark and Wintershall Dea.

"The consortium is maturing one of the most progressed carbon capture and storage projects inside Danish jurisdiction and targets the development of CO2 storage capacity offshore Denmark based on reusing discontinued offshore oil and gas fields for permanent CO2 storage," the drilling company said. The aim is to develop offshore storage with the capacity to store approximately 3.5 million tons CO2 per year by 2030.

As part of its commitment to the consortium, Maersk Drilling has pledged to contribute know-how and limited funding to the initial phases of the project.

Ships to Carry CO2 to Offshore Storage

The project aims at building infrastructure and capabilities that will enable CO2 captured in onshore facilities to be transported offshore for injection and storage beneath the seabed. The first phase of the project will be a feasibility study to validate reservoir compatibility, followed by a pilot to test CO2 injection. The Geological Survey of Denmark and Greenland (GEUS) will act as a research partner to the project, conducting specialized laboratory experiments and results in analysis.

The project aims to store CO2 captured onshore 1700 meters beneath the seabed. For the onshore capture, proven carbon capture technology can be used at carbon-intensive facilities, for example, industrial plants or power plants, the company said.

The captured CO2 will be bunkered in ports and transported by ship to the offshore storage platform which will reuse existing infrastructure originally built for oil and gas production.

At the offshore platform, the CO2 will then be injected for permanent storage beneath the seabed using repurposed oil and gas wells. The consortium has set a goal of developing the capacity to store approximately 3.5 million tons CO2 per year by 2030. This puts the project in the range of delivering CO2 storage corresponding to 15-20% of the reduction required to reach Denmark’s reduction target in 2030.

First well in 2025

The target is to have the first well ready for injection from the Nini platform offshore Denmark in 2025.

Longer-term, the goal is to develop the capacity to store approximately 3.5 million tons CO2 per year by 2030, matching the Danish Climate Council’s recommendations of actions needed to meet Denmark’s 70% reduction target.

"Maersk Drilling expects that its offshore rigs will be used to repurpose the existing oil and gas wells for CO2 injection," the drilling company said.

CEO J?rn Madsen, Maersk Drilling:"We’re really excited to be joining this effort to support the green transition by using the facilities and capabilities of the offshore industry and Maersk Drilling’s more than 40 years of experience with drilling wells in the North Sea. As the Danish government recently stated in its climate plan, carbon capture and storage is an important component in the efforts needed to reach the goal of reducing Denmark’s emissions by 70% by 2030. For Maersk Drilling, the project is part of our innovation initiatives and an attractive opportunity for building additional competencies and broadening the use of our rigs."

"At Wintershall Dea we are very certain: the global energy transition is happening, and we intend to play a decisive role in it. One way we will do so is through technology and innovation projects like this. Offshore CO2 storage can have a significant contribution to a cleaner energy future and the potential to significantly mitigate CO2 emissions in Denmark,” says Hugo Dijkgraaf, Chief Technology Officer of Wintershall Dea. “Thus, we really appreciate the support of the Danish authorities to fund this important endeavor.”

In addition to taking part in the offshore carbon storage consortium, Maersk Drilling has reminded it is working to reduce the emissions associated with offshore drilling in multiple ways. This includes the first-ever rig to operate onshore power and the upgrade of two jack-ups to hybrid, low-emission rigs.
