Input/Output Overview: How H2Gen Works

H2Gen operates by utilizing two key inputs: water (in the form of steam) and off-gas from industrial processes. Through its innovative design, the system efficiently converts these inputs into two valuable outputs:

• Hydrogen: Produced in a single step without requiring electricity, this hydrogen is ready for use in industrial, mobility and energy applications.
• Enriched carbon dioxide (CO₂): A concentrated CO₂ stream that can be captured for reuse or storage, offering an additional pathway to decarbonization.

This seamless process eliminates the need for additional purification steps, optimizing efficiency and reducing operational costs.

Simplified Process Flow: Inputs, Transformations and Outputs

The H2Gen process flow leverages advanced engineering to seamlessly convert off-gas and steam into hydrogen and enriched CO₂. The process is designed for efficiency, modularity and adaptability, ensuring optimal performance in diverse industrial environments.

Key Process Stages:

1. Off-Gas Pre-Processing: Off-gas enters the system and undergoes pre-treatment to remove particulates, moisture and contaminants. This ensures a clean feedstock for the reactor.
2. Steam Integration: Water, in the form of steam, is introduced and carefully regulated to balance the reaction dynamics within the system.
3. Solid Oxide Reactor: The heart of the system, this proprietary reactor uses a solid oxide membrane to facilitate the conversion of steam and off-gas into hydrogen and CO₂ in a single step, without mixing the streams directly.
4. Hydrogen Purification: The produced hydrogen is separated and condensed, delivering >99% purity without the need for external purification systems like PSA beds.
5. Enriched CO₂ Stream: A concentrated stream of CO₂ exits the reactor, ready for capture or reuse, aligning with decarbonization goals.

This streamlined process allows H2Gen to deliver industry-leading performance with a smaller footprint and lower costs compared to traditional methods.
