In this paper, we present the research results related to the project "Development and implementation of a scalable co-generation power plant solution integrating solar energy and biomass utilisation". Our objective is to develop an integrated solution in the field of local renewable and sustainable energy production, storage and use, where solar energy collected by PV/T collector, hydrogen and oxygen gas production by water decomposition, and biogas production by biomass utilisation are integrated into an innovative process, in different scales (scalable), to produce a compact device, which stores solar energy in the form of combustible gas in a container. Our research team members are working on different areas of tasks to achieve this goal. This article reviews the results of the first phase of this work, which involved a literature review and a groundwork.
