‘Plant-as-a-Product’ Offers Solution for Making Green Hydrogen

Wison Engineering and Sungrow Hydrogen have introduced MegaFlex, a “plant-as-a-product” solution to optimizing green hydrogen production.

This fully integrated system is designed for flexible deployment, reduced construction complexity, and broad scalability. By lowering the levelized cost of hydrogen—the average cost to produce hydrogen over a plant’s lifetime—this innovation could accelerate the role of green hydrogen in the global clean energy transition.

Plant-as-a-Product Concept

Wison and Sungrow are setting a new industry standard with the launch of MegaFlex. Establishing a plant-as-a-product approach, rather than introducing new electrolysis technology, is a holistic reimagining of the green hydrogen production system. Instead of custom-built plants, MegaFlex introduces a standardized, replicable model designed for global scalability. Its modular design simplifies construction through intelligent engineering and pre-configured systems.

The fully integrated design encompasses all essential components, including electrolysis equipment, power supply, cooling units, water treatment systems, and automated control systems. Standardization enables faster project delivery, reduces construction costs, and improves reliability by minimizing uncertainties.

Designed for Efficiency

The system’s standout feature is its fully outdoor water electrolysis capability, powered by Sungrow’s advanced technology. Engineered to endure extreme temperatures and protected against water intrusion, dust, corrosion, lightning, and intense sunlight, the system is highly resilient in the toughest climates.

This outdoor design allows MegaFlex key advantages over traditional hydrogen plants. It eliminates the need for costly housing structures, reducing overall system costs by 11.5% and the physical footprint by 15.5%. These reductions cut both embodied and operational carbon because less construction means fewer materials, and smaller footprints demand less energy to maintain. The compact, robust design opens up opportunities to deploy hydrogen production in remote or resource-constrained environments.

Scalable by Design: Mega + Flex

The MegaFlex system takes its name from its massive 500 MW single-unit hydrogen production capacity (Mega) and its remarkable flexibility to scale up to gigawatt-level projects or down to smaller applications (Flex). This modular, standardized architecture shifts from traditional plants, making deployment faster, cheaper, and more reliable across global markets.

Enhancing this flexibility is Wison’s integrated RelPS intelligent simulation platform, which fine-tunes system configurations and control strategies based on renewable energy inputs, demand patterns, and site conditions. This optimization reduces both capital expenditure and long-term operational costs.

Accelerating the Green Hydrogen Market

MegaFlex “plant-as-a-product” represents more than just a technical innovation. It offers a strategic leap forward in the global green hydrogen market. As a vital input for low-carbon fuels like green ammonia and green methanol, green hydrogen is poised to play a central role in decarbonizing hard-to-abate sectors, such as aviation and shipping.

With the rising demand for sustainable aviation fuel and synthetic green fuels, and a general global need to reduce fossil fuel use, this approach will help meet growing energy transition needs while making green hydrogen more accessible and cost-effective.

The first real-world deployment of MegaFlex is planned for ACME’s green ammonia project in Oman.
