Elcogen elcoStack® E3000 G2 Reversible Solid Oxide Stack
3 kW SOFC and 9 kW SOEC stack for power and hydrogen systems
Elcogen elcoStack® E3000 G2 Reversible Solid Oxide Stack
The Elcogen elcoStack® E3000 G2 is a reversible solid oxide stack for system developers integrating efficient electricity generation and high-temperature hydrogen production. Built from more than 100 elcoCells®, it delivers 3,000 W electrical output in solid oxide fuel cell (SOFC) mode or accepts 9,000 W electrical input in solid oxide electrolyser cell (SOEC) mode, with hydrogen production up to 3 Nm³/h. The G2 platform is designed for broad load operation, improved durability and scalable manufacturing.
Product Overview
The E3000 G2 is a core electrochemical component for integration into pilot, commercial and industrial energy systems. It can be configured for electricity generation, hydrogen production or reversible solid oxide cell operation where the surrounding balance-of-plant system supports both operating modes.
The stack is suitable for system integrators, hydrogen technology developers, industrial decarbonisation projects, research organisations and organisations developing distributed power or combined heat and power systems.
How It Works
In SOFC mode, oxygen from the air side is electrochemically transported through the ceramic electrolyte and reacts with fuel at the fuel electrode. This process generates electrical power and useful heat without conventional combustion.
In SOEC mode, electrical energy drives the reverse process. High-temperature steam is converted into hydrogen, while oxygen is produced on the air side. Operating at elevated temperature can reduce the electrical energy required for electrolysis, particularly where suitable industrial waste heat can be integrated into the system.

Applications
- Commercial and industrial electricity generation
- Combined heat and power systems
- Data centres and critical infrastructure power
- Distributed and off-grid power systems

The stack is an application-flexible platform intended to be incorporated into purpose-designed third-party systems rather than restricted to one fixed end-use configuration.
Compatibility and Selection Guidance
The E3000 G2 is the electrochemical stack component and is not, by itself, a complete fuel-cell generator or hydrogen-production system. A complete installation normally requires engineered air, fuel and steam delivery; gas conditioning; thermal management; insulation; sensors; control hardware; power electronics; heat recovery and appropriate safety systems.
Hydrocarbon fuels and ammonia may require suitable reforming, cracking, purification or other fuel-conditioning equipment before entering the stack. In SOEC operation, the steam supply, steam utilisation, temperature control and hydrogen-side gas conditions must be matched to the intended operating point.
Before ordering, users should confirm the required operating mode, fuel or feed composition, electrical load profile, hydrogen-production target, duty cycle, expected thermal cycling, balance-of-plant scope and system-level control requirements. Any pressure or specialised gas-composition requirements should also be reviewed during the integration process.

Frequently Asked Questions
Can the E3000 G2 operate as both a fuel cell and an electrolyser?
Yes. It is designed as a reversible solid oxide stack. However, the surrounding system must include the gas-handling, thermal-control, electrical and safety equipment required for each operating mode.
What is the stack’s electrical capacity?
In SOFC mode, the published output is 3,000 W at 83–112 V with a maximum current of 30 A. In SOEC mode, the published input is 9,000 W at 142–180 V with a maximum current of 60.5 A.
How much hydrogen can it produce?
The published hydrogen-production rate is up to 3 Nm³/h in SOEC operation, with a manufacturer-reported energy-consumption benchmark of approximately 33 kWh/kg.
What fuels can be used in fuel-cell operation?
The manufacturer identifies hydrogen, natural gas, LNG, biogas, methanol, ammonia and other hydrocarbon fuels. The required reforming, gas-cleaning and conditioning system depends on the selected fuel.
Is the E3000 G2 a complete turnkey hydrogen generator?
No. It is a solid oxide stack intended for integration into a complete system. Steam generation, gas management, heating, controls, power electronics and safety equipment must be defined separately.
What information is required for a quotation?
Please provide the intended SOFC, SOEC or reversible operating mode; fuel or feedstock; target power or hydrogen output; anticipated operating hours; load profile; available utilities and the required balance-of-plant or integration scope.
