Project description
A hot idea for clean and sustainable hydrogen production powers towards commercialisation
When hydrogen and oxygen are combined in a fuel cell to produce electricity (a flow of ions), the only by-products are water and heat. However, there are many ways to produce hydrogen gas, many of which are not emission free. Generating hydrogen gas from renewable energy sources results in so-called 'green hydrogen', and it is the focus of the EU-funded HYDROSOL-beyond project. The team is culminating its HYDROSOL series of Horizon 2020 projects, aiming to optimise its hydrogen production plant that produces hydrogen via concentrated solar thermal power. Technical improvements and enhancements in process control will remove any remaining bottlenecks to commercialisation and uptake.
Objective
The HYDROSOL-beyond proposed action is a continuation of the HYDROSOL-technology series of projects based on the utilization of concentrated solar thermal power for the production of Hydrogen from the dissociation of water via redox-pair-based thermochemical cycles. HYDROSOL-beyond is an ambitious scientific endeavor aiming to address the major challenges and bottlenecks identified during the previous projects and further boost the performance of the technology via innovative solutions that will increase the potential of the technology’s future commercialization. In this context, HYDROSOL-beyond will capitalize on the 750kWth existing operational infrastructure, built in the HYDROSOL-Plant project, as well as on a “cluster” of relevant solar platforms and units (owned & operated by the project partners) in order to collect diverse experimental data from a wide range of achievable solar power (50-750kWth) facilities. This way HYDROSOL-beyond will have the flexibility of assessing the proposed novel approaches both under realistic environments and at different scales. The main objectives of HYDROSOL-beyond are:
• the minimization of the parasitic loses mostly related to the high consumption of inert gas via the introduction of innovative concepts for the purification and the potential full recycling of the utilized gases
• the efficient recovery of heat at rates >60%
• the development of redox materials and structures with enhanced stability (>1,000 cycles) and with production of hydrogen ~three times higher than the current state-of-the-art Ni-ferrite foams
• the development of a technology with annual solar-to-fuel efficiency of ≥10%
• the improvement of the reactor design and introduction of novel reactor concepts
• the development of smart process control strategies and systems for the optimized operation of the plant
• the demonstration of efficiency >5% in the field tests, i.e. during operation at the 750kWth HYDROSOL solar platform (PSA, Spain)
