Q&A: Adnoc says CCS ready for scale now

Carbon capture and storage (CCS) projects look likely to draw more attention at the UN Cop 28 climate summit in Dubai later this month, with president-designate Sultan al-Jaber calling for an ambitious 30-fold scale-up of global capacity to help the world reach its net zero goals. Sophie Hildebrand, chief technology officer of Abu Dhabi's state-owned Adnoc, spoke with Argus on 10 November at the site of a CO2 injection pilot project the company is developing with Oman-based 44.01 in Fujairah. Hildebrand touches on Adnoc's CCS ambitions, the prospects for technology globally and the role it can play in the wider transition to net zero.

Edited highlights follow:

Sultan al-Jaber said global CCS capacity needs to rise 30-fold globally. How long do you think we will need to reach this target?

I think CCS is a technology that is ready for scale right now.

The exact date [we will reach that], I don't know, but we need to get after this faster, because this is a technology that we've known about, that we know how to implement, and we just need to work together to scale. And as we scale, we will also drive the cost down, which will enable that scaling to happen even faster.

US climate envoy John Kerry said the oil and gas industry had a responsibility to prove that CCS, in the context of oil and gas projects, is feasible, and is going to deliver the emissions reductions that the world needs. Do you think the industry, and Adnoc specifically, is doing enough now to scale up the technology?

Adnoc has an ambition to have 10mn t/yr of CCS capacity. We have already been operating the Al-Reyadah facility for a number of years that is capturing 800,000 t/yr.

We've announced the Habshan 5 project, with a capacity of 1.5mn t/yr, and the Ghasha project, also with 1.5mn t/yr. We're scaling up our capacity, and I think with the scale up, again, you'll see the costs coming down. One of the things about the energy industry that's really important is that we've been managing complex engineering projects for years. Energy companies are specifically well situated to help drive these projects forward.

At Adnoc we have an ambition to decrease our carbon intensity by 25pc by 2030 [from a 2019 baseline] on our products and be net zero by 2045. [Adnoc has a target to reach net zero operational emissions by 2045]. 
Adnoc has been operating Al-Reyadah, so we are absolutely progressing the activity forward, and Adnoc will be part of the solution also in terms of driving the cost down.

At the moment, we have three carbon capture pilots: this one, one [with Fertiglobe] and there's the project with [US renewable energy firm] Lanzatech, which is some way off, but still within the CCU umbrella.

You mentioned the 2045 target. How much of that is going to include CO2 capture?

Adnoc has a capacity to get to 10mn t/yr by 2030, and that's our initial commitment. We announce the projects as they firm up. So far, we have almost 4mn t committed in carbon capture capacity already.

But of course, our net zero by 2045 pledge isn't solely based on CCUS [carbon capture, use and storage]. There are also low carbon solutions, decarbonisation of our operations and various other things.

This is an 'and' solution. We need lots of different solutions, many different locations. Heavy-emitting industries need solutions to capture their CO2. There are a lot of heavy-emitting industries in the world. Whether it's cement, aluminium. So this is an 'and' conversation, and we need the technology to be scaled, to help drive the cost down. But we also need to be deploying things that we know will work today.

Would Adnoc be able to store that CO2, or are you going to work on more commercial partnerships to collect and store CO2 from other emitters?

At the Al-Reyadah project we are capturing CO2 from Emirates Steel, and utilising it in our operations. I would say there will be multiple pathways forward.

Partnerships are a key part of helping heavy-emitting industries decarbonise. We need to partner with all sorts of different companies, large and small. 44.01 is one of the smaller companies, but we also partner with larger companies to try to figure out what solutions we can put in place faster that can drive the decarbonisation in a profitable manner.

Also, in January we set up a new low carbon solutions directorate, headed by [Adnoc executive director of low carbon solutions] Musabbeh al-Kaabi, and were taking a look at all sorts of mechanisms for not only scaling up CCS, but also the partnership with [US independent] Occidental that we have… so multiple different pathways to help the industry decarbonise, whether it's hydrogen or elsewhere.

Specifically on the storage point, we have aquifers in Abu Dhabi, where we are going to be injecting 18,000 t initially of CO2 from our Fertiglobe operations that are already captured. We have had capture facilities in place there since 2010. We're going to see initial injection this year.

In Europe and the UK Emissions Trading Schemes will become a key driver for CCS as the price or cost of emitting goes up. What makes CCS commercially viable in the UAE?

One of the projects we're working on with Lanzatech, we're trying to take waste streams of gas or CO2 and turn them into viable products. We're using a natural microbial process to do that.

I would say the technologies that create energy efficiency and profitability are the ones that have been scaled fastest. When different technology providers and industries come together and talk about their decarbonisation challenges, the ability for a technology to be profitable, and see overlying profitability, helps that scaling process happen much faster. I think profitability also gets driven by large scale deployment and costs coming down, which is something the energy industry can be key with, as we scale up CCS.

But it's important to note we're not new to CCS… for example, we've operated Al-Reyadah now for seven years. It came online in 2016. It's not a new thing for Adnoc to be entering into this space. It's just an expansion of something we have already been pioneering for a long time. We were the first in the region to have such facilities.

How optimistic are you [on the prospects for CCS]?

I'm extremely optimistic, because I believe that through partnership, collaboration and dialogue, we can solve just about anything.
