What is a containerized electrolyzer?

A containerized electrolyzer is a modular hydrogen production solution that incorporates an entire electrolyzer system with auxiliary components (power electronics, cooling, water purification, and control systems) into a shipping/containerized or skid-mounted container. The system can then arrive on location and be operational in a "plug-and-play" manner without needing foundational civil or infrastructure work and is therefore compact, transportable, and deployable.

Key Applications of containerized electrolyzer

• Producing green hydrogen from renewable energy (solar and wind)
• Hydrogen refueling stations for vehicles with fuel cells.
• Industrial applications for ammonia, steel, glass, and chemical manufacturing.
• Energy storage and grid balancing from excess renewable electricity.
• Remote and off-grid operations such as mining sites or island power systems.
• Backup power applications (data-centers, critical infrastructure).

Segmental Analysis

The containerized electrolyzer market is segmented into product, capacity, application, end-user, and region.

Product Analysis

In 2025, Proton Exchange Membrane (PEM) electrolyzers are expected to be the largest technology segment by revenue in the containerized electrolyzer sector. The PEM electrolyzer's small modular design, high hydrogen purity, fast start-up and shut-down speed, and capability to use intermittent renewable power make it the most viable option in a containerized system. They offer a decentralized green hydrogen generation option for mobile hydrogen fueling stations as well. Companies such as Nel ASA, Enapter, and Siemens Energy have been scaling PEM electrolyzer containerized modules to meet the anticipated demand in North America and Europe.

The Solid Oxide Electrolyzer (SOE) technology segment is expected to be the fastest growing. The advantages of SOEs are high energy efficiency (greater than 90%) while using waste heat from industrial processes or high-temperature energy sources to reduce overall energy consumption in the hydrogen production process. Recent pilot projects in Germany, Japan, and South Korea that focus on combining SOEs and systems using industrial waste heat, are furthering the commercial viability of SOEs. Alkaline electrolyzers remain a less expensive option for large industrial hydrogen production users, but the slower dynamic response limits their use in intermittent renewable energy systems. The Others segment, including Anion Exchange Membrane (AEM) technology, is being propelled forward largely through research and development (R&D) for a cost-efficient option closer to PEM cost and flexibility.

Capacity Analysis

Medium-Scale Systems Dominating While Large-Scale Modules Lead Future Growth

Industry Leaders’ Perspectives

1. Enapter – Giulio Telleschi, VP Engineering

In an interview, Mr Telleschi stressed how Enapter utilizes digitization and cloud-based data to scale modular electrolyzer solutions.

He states, “We have gathered over 2 million operating hours on cloud-based monitoring systems … this data shows our reliability in real world applications, which is what distinguishes us from our competitors.”

He also explained how their “containerised plug-and-play approach ensures easy integration into existing energy systems … The obvious limits of systems and the standard format of interfaces simplify deployment and helps to make big hydrogen projects accessible.”

This view illustrates the importance of modularity, digital monitoring and scalability all of which are required of containerized electrolyzers before they can move from pilot to commercial deployment.

2. LONGi Hydrogen – Wang Yingge, Vice President

In a December 2023 interview, LONGI Hydrogen’s Mr. Yingge elaborated on how LONGI, which is known for PV manufacturing, is now entering the electrolyzer business.

He stated that “hydrogen is a feasible means of energy storage,” especially with the irregularities of renewables and that the company’s strategy began in early 2018 with an annual production capability of electrolyzers by the end of 2022 of 1.5 GW and aiming for 5 GW by 2025.

He added that “whilst cost is a barrier, with wider and more reliable supply-chains with declining components, we see that green hydrogen will be around USD 2.00 per kg in the next 5-10 years.”

That shows how large renewables OEMs expect containerized electrolyzers to be part of the wider energy/storage transition and how they have ambitions to scale manufacturing for modular hydrogen systems.
