The Cambridge Energy Masterclass was a two-day intensive meeting of lectures and discussions, with talks from leading experts in various aspects of energy demand and supply. It focussed on the energy transition and the technologies needed to optimise new energy systems. We discussed the current energy system, and the different contributions provided by a number
Investigating exsolution of metal nanoparticles is an area of evolving interest. Metal nanoparticles have been found to exsolve from metal oxides in the perovskite family under reducing conditions and investigated as fuel cell anodes. Professor Stephen Skinner works at the Department of Materials at Imperial College, and today spoke about the research his group has been carrying
The storage of renewably-generated energy as hydrogen via the electrolysis of water is a fundamental cornerstone of a sustainable hydrogen economy. Conventional electrolysers usually require stable power inputs in order to operate effectively and safely and so may be unsuited to harnessing renewable power, which is often intermittent and diffuse. Professor Mark Symes, from the
PhD student Poorya Shaghaghi recently took part in the 2025 International Video Challenge developed by the journal Buildings & Cities and the Academy for Territorial Development in the Leibniz Assocation. This challenge is open to PhD students worldwide, and gives them an opportunity to showcase their research and explain the significance of their work.
Aquifer thermal energy storage systems can provide a heat source in the winter by extracting warm water from a subsurface reservoir. The extracted fluid cools as it passes through a heat exchanger and is then injected into a colder aquifer. The cold fluid can provide a source of cooling in the summer, absorbing heat rejected
During the last fifteen years there has been a paradigm shift in the continuum modelling of granular materials, most notably with the development of rheological models, but also with significant advances in theories for particle segregation. Professor Nico Gray from the University of Manchester has developed new theoretical and numerical frameworks which couple granular flows
Professor Joe Howe is the Net Zero Professor at the University of Lincoln and the academic lead for the Humber Industrial Cluster. The Humber Cluster spans both banks of the Humber Estuary, connected by the Humber Bridge and hosting the ports of Goole, Grimsby, Hull, Immingham and Killingholme. £18 bn of the UK’s economy is
Particle-driven convection occurs when a layer of fluid containing dense particles is located above a layer of clear, particle-free fluid. This can drive a variation on the classical Rayleigh-Taylor instability, where the particles induce the density difference between the layers. Variants of this instability occur in a number of geophysical flows, such as the undersides
Ten years ago, the Paris COP conference heralded an exceptional meeting to tackle climate change, backed by science, and soon embraced by industry. Much has been achieved, particularly in electrification through the explosive growth of renewables and EVs. However, the original optimism now risks stalling in much of the world as the reality of displacing
Large-scale storage technologies are crucial to balance consumption and intermittent production of renewable energy. At times of excess production, some renewable energy might be converted into compressed air or hydrogen, which is then stored in underground salt caverns. The energy is recovered later, when renewable production becomes insufficient. Herminio Tasinafo Honorio, from Delft University of
