1 | The Global Surge: 3.2GW Delivered, 6GW Cumulative Capacity
According to VNZ Insights’ 2024 Electrolyser Market Report Card, the total electrolyser deliveries more than doubled in a single year. By the end of 2024:
- 3.2GW of electrolysers were delivered to developers worldwide.
- The cumulative installed capacity surpassed 6GW, up from 2.9GW at the end of 2023.
2 | Key Manufacturers: Thyssenkrupp Nucera and China’s Emerging Leaders
The top supplier of 2024 was Thyssenkrupp Nucera, delivering 1.04GW of atmospheric alkaline electrolysers to the Neom green hydrogen project in Saudi Arabia. Other leading suppliers included:
- Envision (0.3GW)
- Peric (0.25GW)
- Sungrow (0.2GW)
- Plug Power (0.2GW)
- Nel Hydrogen (0.2GW)
3 | Regional Distribution: China Takes the Lead
China emerged as the top destination for hydrogen electrolyser deliveries, receiving 1.44GW in 2024, nearly half of the global total. Other major recipients included:
- Middle East & Africa – 1.04GW (entirely for Neom)
- Europe – 0.3GW
- Americas – 0.2GW
- Rest of Asia-Pacific – 0.1GW
4 | Technology Trends: Alkaline Dominates Over PEM

- Atmospheric alkaline – 1.2GW
- PEM (Proton Exchange Membrane) – 0.4GW
- Pressurized alkaline: 2.5GW
- PEM: 0.6GW
- SOEC (Solid Oxide): 0.1GW
5 | Top Orders of 2024: John Cockerill, Siemens Energy, and Peric
In terms of firm orders signed, the top manufacturers were:
- John Cockerill (640MW) – all for AM Green’s Kakinada project in India
- Siemens Energy (400MW)
- Peric (300MW)
- Sungrow (200MW)
- Sunfire (200MW)
6 | Orderbook Concentration: Five Countries Hold 75% of Global Demand
By Q1 2025, 75% of all firm orders originated from just five countries:
- China – 2.8GW
- Germany
- Saudi Arabia
- India
- Sweden
- Thyssenkrupp Nucera (2GW)
- John Cockerill
- Siemens Energy
- Sungrow
7 | Scaling Up: Rise of 200MW+ Projects
The hydrogen market is transitioning from pilot-scale to industrial-scale projects. Facilities exceeding 200MW now account for:
- 42% of total deliveries
- 70% of firm orders
- 105MW National Energy Ningdong Renewable Hydrogen Project (Peric, Verde Hydrogen)
- 75MW Narisong Three Gorges Inner Mongolia Project (Peric, Longi, Tianjin Mainland)
- 60MW Xingguo Foundry Hydrogen Metallurgy Project (Peric, Longi)
- 60MW Damao Banner Project (Phase 1) (Huadian Heavy Industries)
- 45MW Shenzhen Energy Northern PV-Hydrogen Project (Sungrow)
These Insights Are Derived From The VNZ 2024 Electrolyser Market Report Card
