CNOOC Green Hydrogen Strategy, RMB 135 B CAPEX, >1 B k Wh Green Power, and 9 Project Startups (2025)

CNOOC Green Hydrogen Adoption: From Strategy to Execution Risk in 2025

China National Offshore Oil Corporation’s 2025 strategy reveals a deliberate pivot toward building foundational capabilities for green hydrogen production, prioritizing precursor infrastructure over immediate, large-scale hydrogen output. This positions the company as a strategic long-term player but introduces execution risk centered on its ability to develop large-scale renewable energy projects, a departure from its core hydrocarbon business.

• Prior to 2025, CNOOC’s new energy initiatives were less defined within its corporate strategy. The 2025 business plan marks a significant change, explicitly outlining an “integrated development of hydrocarbon sector and new energy sectors” and setting a tangible target to consume over 1 billion k Wh of green electricity, a 30% year-over-year increase.
• This foundational approach contrasts with domestic rivals like Sinopec, which brought major projects like the Kuqa green hydrogen plant online before 2025 and has set aggressive production targets of 120, 000 tonnes annually. CNOOC’s strategy focuses on leveraging its offshore engineering expertise for wind power, a logical precursor to offshore hydrogen production.
• The primary risk shifts from market timing to project execution. While China’s national green hydrogen market is rapidly maturing, exceeding its 200, 000 tonnes-per-year capacity target in 2025, CNOOC’s success is now contingent on its ability to build and scale its offshore wind portfolio effectively.

Green Hydrogen Project Pipeline Grows, Ambition Gap Remains

This chart directly visualizes the theme of ‘execution risk’ mentioned in the section heading. It contrasts the growing project pipeline (strategy) with the ‘ambition gap’ (execution challenges and risks), perfectly aligning with the section’s focus on the difficulties in transitioning from strategy to execution for CNOOC.

$19 B Low-Carbon Budget, CNOOC’s 2025 Integrated Energy Investments

CNOOC’s financial strategy in 2025 supports a dual mandate: maximizing its profitable hydrocarbon operations while funding a methodical entry into the new energy economy. The company’s massive capital expenditure budget is primarily directed at oil and gas but includes significant allocations for low-carbon development and renewable energy infrastructure, de-risking its eventual move into green hydrogen production.

• The total capital expenditure budget for 2025 is set between RMB 125 billion and RMB 135 billion. A substantial part of this, approximately $19 billion, is allocated to increasing oil and gas production under a “green and low-carbon” framework, which includes energy-saving technologies and process optimizations.
• Investment in green power is a direct enabler for future green hydrogen. The company is accelerating green power substitution, with a 2025 consumption goal of over 1 billion k Wh. This investment in demand helps build the business case for more renewable generation, which CNOOC also plans to build.
• While funding its energy transition, CNOOC maintains strong financial discipline in its core business. In Q 1 2025, it reported a low all-in production cost of US$27.03 per BOE, demonstrating the financial strength derived from its hydrocarbon assets that will underwrite its capital-intensive new energy ventures.

China vs. Global, CNOOC’s Focus on Domestic Offshore Energy Dominance

In 2025, CNOOC’s green energy strategy is overwhelmingly focused on the Chinese domestic market, specifically leveraging its decades of experience in the country’s offshore waters to build out renewable power assets. This domestic concentration aligns with national policy and allows the company to integrate new energy projects with its existing oil and gas infrastructure in the South China Sea and Bohai Sea.

• CNOOC’s major project startups in 2025, including the Huizhou 26-6 Oilfield and the Weizhou 11-4 Oilfield, are located in the South China Sea and Beibu Gulf. These projects are developed under a “green and low-carbon” framework, utilizing existing facilities to improve capital efficiency and reduce emissions, a strategy that could incorporate future carbon capture.
• This domestic focus is supported by a rapidly maturing policy environment. In October 2025, China launched its first national green hydrogen subsidy framework, and by year-end, the country’s installed green hydrogen capacity had already surpassed its national target, exceeding 200, 000 tonnes per year.
• While its new energy build-out is domestic, CNOOC maintains international partnerships like its foundation customer status for Australia’s QCLNG project. This demonstrates a proven capability for engaging in large-scale international energy trade, a model that could be applied to hydrogen derivatives like ammonia in the future.

Regional Green Hydrogen Market Size Projected

CNOOC’s Green Hydrogen Maturity: Foundational Tech Over Commercial Production (2025)

CNOOC’s approach to green hydrogen in 2025 is characterized by a focus on technologically mature precursors, primarily offshore wind, rather than deploying commercial-scale electrolyzers. The company is de-risking its future entry into the hydrogen market by first mastering the most capital-intensive component of the value chain: large-scale, captive renewable power generation.

• Between 2021 and 2024, the broader industry discussion focused on pilot projects and electrolyzer efficiency. In 2025, CNOOC’s strategy shows a focus on securing the energy source first, with its plan to “gradually expand the scale of offshore wind power.” This sidesteps the immediate technical and logistical challenges of hydrogen storage and transport.
• The maturity of this strategy is evident when compared to other decarbonization technologies. While some firms like Bloom Energy push for deploying SOFC technology in applications like data centers, CNOOC is concentrating on the upstream energy supply for hydrogen.
• National infrastructure developments in 2025, such as the approval of China’s first cross-provincial green hydrogen pipeline, are solving the midstream challenges that CNOOC is currently avoiding. This allows CNOOC to focus on its core competency in offshore engineering while the broader market ecosystem develops in parallel.

SWOT Analysis, CNOOC’s Hydrogen Strategy Strengths and Market Threats

CNOOC’s strategic position in the emerging green hydrogen market is defined by its formidable strengths in offshore engineering and financial capacity. However, its deliberate, foundational approach creates potential weaknesses related to market timing and exposes it to threats from faster-moving domestic competitors who have already achieved commercial production.

CNOOC’s Next Move: Watch for First Offshore Wind-to-Hydrogen Pilot

The critical inflection point for CNOOC’s green hydrogen strategy will be the sanctioning of its first integrated offshore wind-to-hydrogen pilot project. Such a move would validate its foundational approach, signal a shift from preparation to execution, and provide a clear indicator of its technological and commercial pathway for entering the hydrogen economy.

• If CNOOC successfully accelerates its offshore wind development, watch for a corresponding increase in the “new energy” portion of its annual CAPEX budget beyond 2025. This will be the clearest financial signal of its commitment.
• With China’s national green hydrogen subsidy framework now active, a key indicator will be CNOOC’s participation in subsidy-supported projects. This would confirm its strategy is moving into the commercial development stage.
• A partnership announcement with a major electrolyzer manufacturer or a specialist in offshore hydrogen production technology could be happening. This would reveal its chosen technological path and potential partners for project execution.
