​The project aims to conduct flow-sheeting, industrial scale-up, safety and economic analysis, to improve the fundamental knowledge and efficiency of the S_I cycle H2 production step, and to investigate a solar primary energy source for the H2SO4 decomposition step which is common to both cycles.

​The Project aims to promote the exploitation of concentrated solar energy through small and middle scale facilities.  The project is particularly relevant to local requirements of power and heat. A back-up with the locally available renewable fuels available locally or those which can be easily produced. The project will include testing the CSPtechnology in cites with favourable solar insolation.

​The general project objective is to assess and to develop an innovative (TES) concept having the best potential to provide efficient, reliable and economic energy storage for CSP plants. The experimental programme (will focus on the full development of the integrated system, up to demonstration level.


The DiGeSPo project aims to research and build a modular 1-3 kWe, 3-9 kWth micro Combined Heat and Power (m-CHP) system based on innovative Concentrated Solar Power (CSP) and Stirling engine technology. This CSP m-CHP unit will provide electrical power, heating and cooling for single and multiple domestic dwellings and other small commercial, industrial and public buildings. It integrates small scale concentrator optics with moving and tracking components, solar absorbers in the form of evacuated tube collectors, a heat transfer fluid, a Stirling engine with generator, and heating and/or cooling systems.
