Decoupling strategies in electrochemical water splitting

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

On the thermal drift of an ATES system subject to different heating and cooling loads

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

Decarbonisation of Industrial Clusters

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

Challenges of the Energy Transition

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 energy storage in salt caverns

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

Novel Electrocatalysts for Hydrogen Production

Today was the last seminar of Lent term, and Part III student James Fidler presented his recent work on new catalyst materials for hydrogen production through electrolysis.  Nobel metals are very expensive, and so research is ongoing to find affordable alternatives for catalyst production. Under the supervision of professor Clarke, James has been investigating the

Aquifer thermal energy storage

Professor Matthew Jackson from Imperial College London visited us today and presented his recent work on Aquifer Thermal Energy Storage (ATES) systems. This underground thermal energy storage technology provides large capacity, low carbon heating and cooling to the built environment. Heating and cooling of buildings currently produces 23% of the UK’s greenhouse gas emissions, and

Bubble growth in electrolysis

Methane availability is crucial to the energy transition. Currently, most hydrogen is produced by steam methane reforming, a carbon-intensive process. A small amount of green hydrogen is being obtained from the electrolysis of water; however, for this carbon-free hydrogen to become prevalent, electrolysis must become much more efficient than it currently is.
