Project Description

Nexceris, LLC (Lewis Center, OH) will scale reversible solid oxide cell (RSOC) and stack technology to the prototype system level and demonstrate world-class performance that will allow achieving hydrogen production cost goals at a large-scale system level (100 kW or larger). Nexceris’ cell and stack technology will be leveraged in this project. The goal of the proposed project is to demonstrate a RSOC system with the following attributes: minimum of 1 kW power generation in fuel cell mode (2+ kW in electrolysis mode) and roundtrip stack efficiency (RTE) of at least 60 percent, capability for dynamic switching between fuel cell and electrolysis modes in response to fluctuating grid demands, capability for operating in the pure electrolysis mode to produce hydrogen at sufficiently high efficiency to enable hydrogen cost of less than $2/kg (at scale, assuming an appropriate system design), and flexibility to perform steam electrolysis or steam/CO₂ co-electrolysis.

Project Benefits

The Solid Oxide Fuel Cell (SOFC) Program is committed to developing efficient, low-cost electricity from natural gas or coal with carbon capture capabilities for distributed generation (DG) and central power generation applications; maintaining cell development and core technology research to increase the reliability, robustness, and durability of cell, stack, and system technology; and providing the technology base to permit cost-competitive DG applications and utility-scale systems with carbon capture capabilities. It is anticipated that these projects will develop advanced technologies that can maturate the present state of SOFC and Solid State Electrolyzer Cell (SOEC) technologies to a point of commercial readiness for power generation and hydrogen production.
