Carbon capture and storage A key enabler in the energy transition Carbon capture and storage
1
Carbon capture, use and storage and our role Carbon capture, use and storage (CCUS) is a process that captures carbon dioxide (CO2) emissions from sources like industrial processes or fossil fuel-fired power plants and either reuses, or stores it, so it does not enter the atmosphere. CCUS is a challenging technological disruption essential to reducing CO2 emissions at a large scale. The technology is capable of achieving deep cuts to emissions across carbon-intensive industries enabling us to accelerate towards a net zero future. Our role is to accelerate the transition and support our customers to achieve their sustainability goals.
• Initial engineering phase of 1PointFive’s first direct air capture facility which will capture 500,000 metric tonnes of CO2 annually. • Pre-FEED for Drax Group’s first two carbon capture units at its power station in the UK which are expected to capture 8 million tonnes of CO2 every year.

Reaching net zero will be virtually impossible without CCUS

• Providing preliminary front-end engineering and design services for Shell Canada’s proposed Polaris CCS project. The project would capture carbon dioxide (CO2) from the refinery and chemicals plant located at Shell’s Scotford Complex near Edmonton, Canada.
Our experience extends to more than 200 projects including some of the world’s largest carbon capture and storage projects. This includes: • Chevron Gorgon CO2 reinjection facilities in Australia. We are engaged in engineering, procurement, construction and management that will inject 100 million tonnes of CO2 underground.

We helped Chevron capture CO2 from its Gorgon facility and store it beneath Barrow Island CO2 compressor trains/modules
“
While emerging sources of energy such as solar, wind and hydrogen are critical to a low-carbon future, we also need to reduce the carbon intensity of new and existing hydrocarbon facilities that support our energy needs today.

Finding a solution for CO2 emissions
Safely handling millions of tonnes of CO2 every year
The Gorgon natural gas field contains 14 per cent naturally occurring CO2. This CO2 must be separated from the natural gas stream prior to liquification to prevent it from freezing into a solid.
We were involved in the engineering, procurement, construction, commissioning and start-up activities of the CO2 injection facilities. These facilities process, transport and inject unwanted CO2 into rock formations more than 2 km underground.
The industry standard approach is to vent this CO2 into the atmosphere. But as a cleaner alternative to this process, Chevron began the largest greenhouse gas abatement project ever undertaken in our industry to capture and store CO2 in rock formations beneath Barrow Island in Western Australia, where its Gorgon LNG facility is based.
Our experts implemented several modifications to ensure the injection facilities met their required parameters for water content and injection temperature. To reduce water content and therefore prevent corrosion in the facilities, we used an enthalpy-based
Injections facilities
Cutting emissions by 40 per cent internal refrigeration cycle to increase the dewpoint of the CO2 gas to acceptable levels. Other system improvements included the installation of a hot-gas bypass line, cold-recycle line, methanol and glycol (MEG) injection package and wastewater treatment package. In total, we installed 1,500 new valves, 9 km of process piping and 450 tonnes of supporting steelwork.
We applied our understanding of the intricate behaviour of CO2 at a large scale, along with our experience executing complex projects, to enable the safe start-up of the CO2 injection facilities in mid-2020. As a result, carbon emissions from the Gorgon LNG facility will be reduced by approximately 40 per cent. This equates to four million tonnes of reservoir CO2 injected into the Dupuy Formation beneath Barrow Island each year, which will save approximately 100 million tonnes of CO2 from being emitted over the life of the Gorgon project.

Drax - negative emissions Worley has been awarded a contract to provide the early front-end engineering and design (pre-FEED) for the first two carbon capture units at Drax Group’s power station in North Yorkshire, UK. Each unit is expected to capture approximately 4 million tonnes of carbon dioxide a year.
Customer Drax
Location Yorkshire, UK
Scope Pre-FEED
The carbon capture units will incorporate the negative emissions process scheme, Bioenergy with Carbon Capture and Storage (BECCS). Drax has successfully piloted BECCS which generates renewable electricity while permanently removing carbon dioxide from the atmosphere. Worley’s work includes developing the plant layout, cost estimation and schedules for FEED and detailed engineering, procurement and construction. It will also

explore options to integrate the project into the existing Drax site at an industrial scale and provide studies to optimize performance and cost. This project could result in the power station becoming carbon-negative and contribute to Humber’s ambition to become the UK’s first zero-carbon industrial cluster. It also has the potential to inspire future decarbonization projects from adjacent industries.
Engineering a direct air capture facility for 1PointFive We’ve been awarded the initial engineering phase of 1PointFive’s first direct air capture (DAC) facility.
The facility, located in the U.S. Permian Basin, is the first commercial scale deployment of Carbon Engineering’s DAC technology, which captures carbon dioxide directly out of the atmosphere. This FEED agreement is the first step of an alliance between 1PointFive and Worley. The initial focus of this collaboration is on the Permian Clean Campus targeting DAC 1 through DAC 4.
When complete, the facility will be capable of extracting one million metric tons of atmospheric CO2 annually. It will also help to accelerate the deployment of commercialscale direct air capture technology, which is critical to helping companies around the world meet their ambitious CO2 emission reduction targets.
The FEED phase will focus on the first train, DAC 1, which will capture 500,000 metric tonnes of CO2 annually. Completion is estimated by the end of 2021, after which the alliance will move into the engineering, procurement and construction (EPC) phase for DAC 1. During the FEED phase, we’ll help 1PointFive to explore next-generation technology, materials and manufacturing approaches consistent with a circular economy—from recycled plastics to 3D printing and fully integrated zero-emission power. These innovations will contribute to the facilities’ sustainability and capital efficiency, and the data will help to refine future direct air capture facilities.
