Sustainable Energy Storage
Hydrogen Power in Vehicles
Professor Valeska Ting is based in the Department of Mechanical Engineering where she leads a specialist research team developing the use of nanomaterials – highly useful materials with features between 1 nm and 100 nm in size - for sustainable energy storage and for energy use, such as in hydrogen-powered vehicles.
Her work contributes to the development of safer, more efficient ways to store and deliver sustainable energy. Professor Ting serves on the UK-based EPSRC-led national Energy Strategic Advisory Committee. She is very active in science and engineering outreach and is one of the BBC’s BAME Expert Voices. Professor Ting was named among the Top 50 Women in Engineering in Sustainability in 2020 by the Women’s Engineering Society.

Women in Engineering: Celebrating Sustainability on INWED
Valeska Ting is a Professor of Smart Nanomaterials at the University of Bristol. “I lead a research team that is working on the development of materials-based systems for storage of hydrogen, which is a zero-carbon fuel that can be used in transportation. By conducting research into how we can safely and efficiently store hydrogen onboard vehicles, we are helping to provide underpinning technologies to allow alternative energy vectors such as hydrogen to come into future widespread use."

'Molecular sponge' advancement in storing hydrogen
The research marks a major development in our understanding of efficient hydrogen storage. It was led by Dr Valeska Ting from our Department of Chemical Engineering in conjunction with researchers from Rutherford Appleton Laboratory and collaborators in the USA and Germany.
Toward process-resilient lignin-derived activated carbons for hydrogen storage applicationsACS Sustainable Chemistry & Engineering
2020 Activated carbons are promising sorbents that have been heavily investigated for the physisorptive storage of hydrogen. The industrial process for production of activated carbons is finely tuned and requires a reliable and uniform feedstock. While the natural biopolymer lignin, a byproduct of several industries, has received increasing interest as a potentially sustainable and inexpensive activated carbon feedstock, the ratio of the three aromatic monomers (S, G, and H) in lignin can be heavily affected by the lignin source and growing conditions.
Multifunctional composites: A metamaterial perspectiveMultifunctional Materials
2019 Multifunctional composites offer the ability to increase the efficiency, autonomy and lifespan of a structure by performing functions that would have been considered by designers as mutually exclusive. In the present perspective paper, a subclass of multifunctional composites is considered: metamaterials.
Application of Experimental Design to Hydrogen Storage: Optimisation of Lignin-Derived CarbonsJournal of Carbon Research
2019 Lignin is a significant by-product of the paper pulping and biofuel industries. Upgrading lignin to a high-value product is essential for the economic viability of biorefineries for bioethanol production and environmentally benign pulping processes. In this work, the feasibility of lignin-derived activated carbons for hydrogen storage was studied using a Design of Experiments methodology, for a time and cost-efficient exploration of the synthesis process.
Flexible ZIFs: probing guest‐induced flexibility with CO2, N2 and Ar adsorptionJournal of Chemical Technology & Biotechnology
2019 The experimental isotherms of these frameworks were analysed in order to investigate their structural flexibility using gases with kinetic diameters equal to or larger than the diameters of their static pore apertures. The results of gas sorption measurements indicate guest‐induced phase changes for ZIF‐7 and ZIF‐9 (SOD topologies). ZIF‐12 (RHO topology) also shows uptake for gases, despite its pore‐limiting diameter being smaller than the kinetic diameters of the adsorbed molecules.
Defective hierarchical porous copper-based metal-organic frameworks synthesised via facile acid etching strategyNature.com
2019 Introducing hierarchical pore structure to microporous materials such as metal-organic frameworks (MOFs) can be beneficial for reactions where the rate of reaction is limited by low rates of diffusion or high pressure drop. This advantageous pore structure can be obtained by defect formation, mostly via post-synthetic acid etching, which has been studied extensively on water-stable MOFs.
