ADNOC Refining, a joint venture between the Abu Dhabi National Oil Company (ADNOC), Eni and OMV, is on track to complete the first phase of its waste heat recovery project at its Ruwais facility in Abu Dhabi.

ADNOC claims to produce some of the world’s least-carbon intensive crude and says it is further reducing its greenhouse gas (GHG) emissions intensity by 25% by 2030, aligned to the United Arab Emirate’s net zero by 2050 strategy.


Started in 2018, the $600mn waste heat recovery project will recycle waste heat generated from the gas-powered turbines (which is currently vented into the atmosphere) at ADNOC Refining’s general utilities plant at Ruwais, to produce up to an additional 230 MW/d of electricity – enough to power hundreds of thousands of homes. It will also produce 62,400 m3 of distilled water per day for use in the plant. Overall, the project will increase power production and thermal efficiency at the site by around 30% with no additional CO2 emissions, according to the company.


Phase one of the project, which includes the operation of two new boilers and turbines, will be completed before the end of the year, while phase two, which includes a further two boilers, will be completed around mid-2023.


The waste heat recovery project is one of several initiatives to decarbonise ADNOC’s operations, building on other environmental programmes including the implementation of a zero routine gas flaring policy in the early 2000s and establishing the region’s first commercial-scale carbon capture and underground storage facility in 2016. In the last 12 months the company has announced partnerships to decarbonise its operations at scale, with up to 100% of its grid power being supplied by clean nuclear and solar energy sources, and what is reported to be the first-of-its-kind, subsea transmission network in the Middle East and North Africa (MENA) region which will connect ADNOC’s offshore operations to clean onshore power networks.
