What is Energy Storage, Harvesting and Catalysis all about?
- Developing high-performance batteries for grid-scale and distributed energy storage.
- Producing renewable hydrogen and synthetic fuels through solar and electrochemical routes.
- Designing autonomous energy systems integrating harvesting, storage and smart management.
- Modelling reactors and simulating processes to bridge laboratory innovation and pilot scale.
Energy Storage, Harvesting & Catalysis
The Energy Storage, Harvesting and Catalysis department investigates materials, processes and systems across electrochemical energy storage, sustainable fuels and autonomous energy management. Our research combines materials synthesis, electrochemistry, catalysis, CO₂ valorisation and reactor engineering, with activities spanning from fundamental materials science through to pilot-scale demonstrators. Working through both competitive and industrial projects, we develop and validate technologies that support the transition to a decarbonised energy system.
Electrochemical Batteries
We develop electrochemical battery technologies spanning redox flow batteries and advanced lithium-based systems, combining materials innovation with cell and stack engineering. Our prototypes are validated under realistic operating conditions, targeting applications in grid-scale storage, industrial energy management and distributed renewable systems.
Sustainable Fuels
We develop solar-driven and electrochemical processes for renewable hydrogen production and CO₂ valorisation, achieving solar-to-hydrogen efficiencies above 18% and solar-to-fuels above 15%. Our research also advances plasma-catalytic and thermoconversion routes for synthetic fuel production, with pilot-scale activities in renewable hydrogen and synthetic methane generation.
Harvesting and Supercapacitors
We design supercapacitors for self-sufficient energy systems, integrating energy harvesting and storage to enable effective energy management in remote and distributed applications where grid connectivity is unavailable or unreliable.
Reactor Modelling and Process Simulation
We develop microfluidic models, reactor engineering tools and process simulations to optimise electrolysers, plasma-catalytic systems and chemical reactors, enabling the transition from laboratory-scale innovation through to pilot-scale implementation.

The department operates three specialised laboratories covering the full spectrum of energy storage and conversion. The Battery Laboratory integrates electrode fabrication, cell assembly and electrochemical testing under controlled conditions. The Electrochemistry Laboratory is equipped for photoelectrochemical characterisation, electrolysis and advanced analytical techniques including gas chromatography and mass spectrometry. The Catalysis Laboratory supports catalyst development, reactor testing and plasma-catalytic process validation. Complementary analytical platforms (XRD, SEM, BET, TEM) are available through institute-wide shared infrastructure.
Tech Transfer
The Energy Storage, Harvesting and Catalysis department translates its research into practical solutions through close collaboration with industrial partners, system integrators and public institutions. Our technology transfer activities span battery technologies for grid-scale and industrial applications, solar-fuel reactors, power-to-gas systems and plasma-catalytic processes for CO₂ valorisation. Through competitive and industrial projects, we have delivered demonstrators and pilot plants validating these technologies at pre-commercial scale.
