Solar To Hydrogen Hybrid Cycles




To demonstrate that hydrogen "green" production is possible through the exploitation of solar power.

Project Summary

The FCH JU strategy has identified hydrogen production by water decomposition pathways powered by renewables such as solar energy to be a major component for sustainable and carbon-free hydrogen supply. Solar-powered thermo-chemical cycles are capable to directly transfer concentrated sunlight into chemical energy by a series of chemical and electrochemical reactions, and of these cycles, hybrid-sulphur (HyS) cycle was identified as the most promising one.The challenges in HyS remain mostly in dealing with materials (electrolyser, concentrator, acid decomposer/cracker and plant components) and with the whole process flowsheet optimization, tailored to specific solar input and plant site location. With recent technology level at large-scale hydrogen production concepts hydrogen costs are unlikely to go below 3.0-3.5 €/kg. For smaller scale plant, the costs of hydrogen might be substantially higher.


The project focuses on applied, bottle-necks solving, materials research and development and demonstration of the relevant-scale key components of the solar-powered, CO2-free hybrid water splitting cycles, complemented by their advanced modeling and process simulation including conditions and site-specific technical-economical assessment optimization, quantification and benchmarking. For the short-term integration of solar-power sources with new Outotec Open Cycle will be performed. Simplified structure, extra revenues from acid sales and highly efficient co-use of the existing plants may drop hydrogen costs by about 50-75% vs. traditional process designs.

ES Role

EnginSoft will provide MODAO tools and metamodelling methods in order to simulate the full process performances, including elaboration of DoE strategy, data mining and optimisation. EnginSoft will also help SME and R&D performers in modelling issues, simulation of the relevant processes and elaboration of the models. EnginSoft has also the coordination of the project.

Some of our competences in research and technology transfer

Research project


Atmospheric Sub-system Engineering

The objective was to design, study and characterize the atmospheric sub-system of a Plant Control Unit and its processes related to crop growth. The atmosphere of the plant-related environment had to be homogeneous and meet the plants’ requirements.

Research project


Optimizing Industrial Applications for Heterogeneous HPC systems

OPTIMA is an SME-led project that aims to harness and optimize several industrial applications and a set of open source libraries. These will be used in at least three different application domains on two new HPC systems populated with FPGA integrated circuits and using several innovative programming environments.

Research project


Simulation Technology Aeronautic Research

A virtual design environment created for the study of casting and welding processes, of surface and massive heat treatment, and of operational performance of alloy steel-made products, using a design chain approach.
