RV Jones Lecture 17 04 13: Prof Guy Houlsby — Tidal Power: Opportunities for the UK

This is a transcript of an RV Jones lecture of unknown duration, delivered by Guy Houlsby, Professor of Engineering Science at the University of Oxford, with the theme centred on "Tidal Energy – An Opportunity for the UK." The RV Jones lecture series is named in memory of R.V. Jones, the renowned British scientific intelligence officer, and regularly invites leading scholars to explain cutting-edge scientific and technological topics to the public. This particular session is a talk that combines both academic depth and a public-facing perspective. The core highlight lies in how Professor Houlsby systematically sets out the technical pathways for tidal power generation, moving from traditional tidal barrages and tidal lagoons to emerging tidal stream devices. Drawing on the UK's uniquely favourable tidal resource conditions, he explores the economic feasibility, environmental impacts, and policy challenges involved. He not only unpacks the underlying technical principles but also, from an engineer's standpoint, estimates generation costs and assesses the real-world deployment potential, helping audiences understand why tidal energy is regarded as an important piece of the UK's energy transition puzzle rather than a pipe dream. This lecture is well suited to students and engineers in the renewable energy field, practitioners concerned with marine engineering and climate policy, as well as general audiences interested in UK energy strategy. It is advisable to gain a basic understanding of tidal energy concepts before watching, and to pay attention to the cost calculations and resource distribution maps presented during the talk, pausing where necessary to digest the material. For anyone seeking a deeper understanding of how the UK is converting ocean power into clean electricity, this lecture offers an excellent starting point and a valuable next step.
