Lastly, declining green electricity costs, particularly in key regions, will enhance the economic viability of green hydrogen.

3. Capacity Inflection Point: Initiation in 2025, Explosion from 2027 to 2030

As of the end of 2023, the global installed capacity of green hydrogen is approximately 1.4 GW, with projections indicating an increase to 5 GW in 2024. This growth drives demand for industrial hydrogen generators and laboratory hydrogen generators globally. In China, the installed capacity is around 2.5 GW, accounting for over 50% of the global total. By the end of 2025, China's annual green hydrogen production capacity is expected to reach 200,000 tons, and cumulative global electrolyzer capacity will exceed 10 GW. By 2027, cumulative global electrolyzer capacity is projected to reach 50 GW, with annual green hydrogen production exceeding 1 million tons.

Looking ahead to 2030, global annual green hydrogen production capacity is projected to reach 38 million tons, according to IEA forecasts. This growth will signify the entry of the industry into a phase of scalable profitability and a marked enhancement in industry maturity.

Several major projects are set to come online in 2025, including initiatives such as Datang Duolun and Guohua Cangzhou. Internationally, the Saudi NEOM project is reported to be 80% complete, with production expected to begin in mid-2026, yielding 650,000 tons of green ammonia annually. Furthermore, global investments in the green hydrogen sector are projected to reach $4.3 billion in 2024, with expectations for this figure to rise to $8 billion in 2025.

4. Application Inflection Point: Gradual Development Across Sectors

In the industrial sector, significant breakthroughs are expected between 2027 and 2028. Synthetic ammonia production is anticipated to achieve profitability under a carbon price scenario of $70 per ton, with an annual replacement potential of 30 million tons. The methanol and refining sectors are projected to reach a target penetration rate of 7% by 2030, resulting in an annual demand of 2.7 million tons. Additionally, large-scale adoption of hydrogen-based furnaces in steel production is expected to occur post-2030.

In the transportation sector, gradual penetration of green hydrogen is anticipated. Heavy-duty transport is expected to achieve commercialization by 2030, with a projected market share of 20% by 2040. In the shipping and aviation industries, scalable applications of green ammonia and green alcohol fuels are expected to emerge after 2028, with these fuels reaching acceptable cost levels.

This timeline indicates that the synthetic ammonia and methanol sectors will reach their inflection points between 2027 and 2028, marked by green hydrogen costs falling below $2.10 per kilogram. In the steel metallurgy sector, the inflection point is expected between 2028 and 2030, with stable operations of hydrogen-based furnaces marking substantial progress.

5. Investment and Policy Inflection Points: Intensive Policy Rollout from 2025 to 2027

The investment inflection point will see a transition from government-led initiatives to a dual-driven model of "government + market," with private sector investment exceeding 50% by 2025. This shift will facilitate balanced investments across the industrial chain, encompassing upstream electrolyzers, midstream storage and transportation, and downstream applications. Notably, China is leading this charge, with plans to establish a $30 billion equipment industry cluster by 2030.

Recent policy developments are poised to act as a catalyst for growth in the green hydrogen sector, creating favorable market conditions for hydrogen equipment manufacturers. Currently, 28 countries worldwide have included green hydrogen in their "carbon tax rebate lists." Notably, the European Union's Carbon Border Adjustment Mechanism (CBAM) offers tariff reductions ranging from 5% to 8%.

In China, the "14th Five-Year Plan" places a strong emphasis on supporting green hydrogen, with a target production capacity of 3 million tons by 2030. Additionally, carbon prices are projected to rise significantly, with estimates indicating that the global average could reach $70 per ton by 2030.

6. Comprehensive Assessment: Market Inflection Point from 2025 to 2027

The green hydrogen market inflection point is anticipated to arrive between 2025 and 2027. In 2025, the commercialization year, multiple large projects will commence operations, with regions such as Northwest China, the Middle East, and Australia achieving economic viability first. The period from 2026 to 2027 will represent a comprehensive inflection point characterized by cumulative global electrolyzer capacity surpassing 50 GW. By 2030, the market will enter a maturity phase, with green hydrogen costs falling below $2.00 per kilogram, fully replacing gray hydrogen.

7. Key Verification Indicators for the Arrival of the Inflection Point

To confirm whether the green hydrogen market inflection point has genuinely arrived, several key indicators should be monitored.
