A review on biomass derived syngas for SOFC based combined heat and power application

Solid oxide fuel cells (SOFC) is in focus to integrate with biomass gasification technologies to have a single and highly efficient system; combining the benefits of renewable energy sources and hydrogen energy systems. Combined heat and power (CHP) for houses is highly efficient (>90%). Micro CHP for space heating in Europe and Japan is already been popular using natural gas as fuel. Biomass derived syngas μ-CHP is more interesting. A brief overview of the systems, the present status and the future prospect of the technology has been discussed in this review to offer the guideline of its way for implementation. Since SOFC exposes to syngas derived from biomass gasification, SOFC material needs to be developed, particularly anode part, for the better sulfur tolerance and inhibit carbon deposition. The different anode materials have been discussed to have a guideline for future development. By the development of SOFC material, the entire energy integration system seems to offer greater energy efficiency for sustainable and renewable energy route. Biomass-SOFC based micro CHP’ integrated system for residential and commercial applications.
