Project description
Sustainable artificial tree solution for H2 production
H2 is a promising alternative for sustainable fuel, gaining increasing interest in recent years, and it could prove critical to green efforts. Unfortunately, despite this interest, few solutions are currently available for its efficient and on-demand production, as options are expensive or inefficient. The ERC-funded SOLAR-H2 project aims to develop an artificial tree-like technology for the on-demand distributed production of H2. This solution would have near-zero operational costs by using solar energy and capturing reactants from the ambient air instead of high-purity water and grid electricity. To achieve this, the project will utilise photo-electrocatalysis along with a closed-loop CO2 recirculation system to improve sustainability and carbon efficiency.
Objective
The SOLAR-H2 project introduces a groundbreaking artificial tree (AT)-like technology for distributed, on-demand H2 production, designed for zero-carbon communities and off-grid applications. Unlike conventional electrolysers requiring high-purity water and grid electricity, this system has near-zero operational costs, leveraging solar energy and capture of reactants from the ambient.
The aim is to develop a showcase prototype for the Solar Hub under development at the Univ Messina to present to stakeholders the potential of AT technologies.
The innovative approach integrates photo-electrocatalysis, where CO2 and H2O are converted into H2 and formic acid (FA) using sunlight. The latter acts as a hydrogen storage medium, enabling on-demand or continuous H2 production, even during the night, through catalytic decomposition. Additionally, the system ensures a closed-loop CO2 recirculation, with minimal losses compensated by external CO2 sources, making it a highly sustainable and carbon-efficient solution.
Building upon the ERC Synergy SCOPE project, SOLAR-H2 aims to advance the technology to TRL4. This will involve scaling up to a small-scale demonstrator, improving performance and gas-diffusion electrodes as well as the cell for stable continuous operation, and integrating the systems for capturing reagents and the storage/decomposition-on-demand of FA. The project assesses techno-economic and socio-environmental aspects, along with a market analysis to identify key barriers and opportunities.
The exploration strategy is to build a first demonstrator for the Solar Hub to foster this important area of solar-to-chemical conversion and lay the foundation for a spin-off company, positioning formic acid as a breakthrough hydrogen vector in the clean energy transition. By bridging the gap between lab-scale research and industrial feasibility, SOLAR-H2 will de-risk the transition paving the way for large-scale adoption of sustainable H2 production technologies.
