The first track of ADNOC‘s strategy materializes through its joint ownership in Masdar, which is aggressively pursuing market leadership with established BESS technology.

• The centerpiece of this strategy is Masdar’s development of the world’s largest solar-plus-storage project, announced in October 2025. This initiative combines 5.2 GW of solar PV with a 19 GWh BESS, representing a total investment of approximately $5.9 billion.
• This project, executed in partnership with battery manufacturer CATL, immediately positions ADNOC via Masdar as a major player in the global grid-scale storage market, far exceeding the initial internal project scopes seen in prior years.
• This move aligns with the UAE’s broader energy goals and addresses the intermittency of its rapidly expanding renewable energy portfolio, with Masdar targeting 100 GW of renewable capacity by 2030.

ADNOC’s Direct Decarbonization and Technology Pilots

The second track involves ADNOC directly implementing storage solutions to decarbonize its own operations while exploring alternative technologies to conventional lithium-ion.

• For its own oil and gas operations, ADNOC established a target to deploy 500 MWh of BESS capacity by 2030, specifically to replace carbon-intensive diesel generators. The foundational work for this occurred in 2025, culminating in the approval of WHES as its first official BESS equipment supplier in December 2025.
• Separately, in June 2025, ADNOC announced a trial of a novel kinetic battery technology with Houston-based Revterra. This pilot uses rotational energy storage with recycled steel, signaling a strategic effort to find alternatives to mineral-dependent supply chains.

$13 B in Financing, ADNOC Capital Allocation for Green Innovation

ADNOC‘s aggressive move into energy storage is supported by a significant financial restructuring that allocates capital for green innovation alongside its core business. In December 2025, the company secured a landmark $13 billion financing package explicitly designed to fund both decarbonization of existing gas projects and new ventures in clean technology. This financial strategy provides the necessary capital to de-risk its entry into the new sector while maintaining profitability from its hydrocarbon assets.

Capital for Utility-Scale Projects

A substantial portion of new funding is directed towards large-scale, market-ready renewable and storage projects, primarily through its subsidiary structure.

• The most prominent example is the financing structure for Masdar’s $5.9 billion solar-plus-storage project. This investment demonstrates ADNOC‘s ability to leverage its financial strength and partnerships to execute projects at a scale few competitors can match.
• The investment strategy supports the rapid growth of the UAE’s domestic energy storage market, which is projected to reach an installed capacity of 1.2 GWh in 2025 and grow at a compound annual growth rate of 55%.

Funding for Innovation and Local Supply Chains

Beyond large projects, capital is also being strategically deployed to foster innovation and build a resilient local supply chain, mitigating long-term risks.

• The pilot project with Revterra for kinetic battery technology, while smaller in scale, represents a strategic investment in diversifying technology options and exploring solutions with localized supply chains, such as using 100% UAE steel.
• By acting as a major offtaker and approving local suppliers like WHES, ADNOC is using its balance sheet to catalyze the development of regional capabilities in the BESS sector, aligning with the UAE’s industrial diversification goals.
