SHOWCASE #1
Solid Oxide Electrolysis Cell (SOEC)
Showcase #1 is an opportunity to test lines #1, #8, and #9, enabling the creation of a case study that can serve as a reference for startups and SMEs looking to leverage these services. By validating different aspects of high-temperature electrolysis, this initiative will provide key insights into the technical feasibility, design optimization, and environmental impact of this cutting-edge hydrogen production technology.
H2B2 is developing a high-temperature electrolysis stack [DMA1] designed to produce low-carbon hydrogen more efficiently. This innovative system leverages Solid Oxide Electrolysis Cells (SOECs), which operate at 800-900°C, significantly reducing the electrical energy required for hydrogen production compared to conventional electrolysis technologies.
A key innovation in this stack is the integration of 3D printing technology in the manufacturing process. Using stereolithography (SLA), H2B2, in collaboration with IREC, has developed corrugated electrolyte membranes, enhancing hydrogen output and mechanical stability while maintaining a compact stack design. This breakthrough optimizes performance, simplifies component integration, and improves the system’s overall efficiency and cost-effectiveness.
