Speech Title: Grid integration of clean power and electric transportation
Abstract: Recent applications of power electronics converter for transmission and distribution networks will be summarised. Technologies and efforts on decarbonising transport by electrification in the UK will be discussed. An example of National Innovation Competition (NIC) project led by Scottish Power will be presented. This project will covert an AC line to DC operation in North Wales in order to increase the power transfer capability of exiting circuit in order to accommodate more renewable power generation and electric vehicles. As the Chair of UK and Ireland Chapter of IEEE PELS, Prof Liang will talk about the recent efforts of PELS and the Chapter in order to attract more engineer and researcher, particularly your persons, to the power electronics fields.

Dr. Paul Leahy
University College Cork, Ireland
Paul Leahy is Stokes Lecturer in Wind Energy at UCC and Funded Investigator at the MAREI Research Centre. He leads a multidisciplinary team of five Master’s and PhD students and one postdoc. The team’s research addresses critical climate change impacts and adaptation challenges including: integration of renewable energy sources into the power systems of the future; climate change impacts on extreme events and anthropogenic greenhouse gas emissions.
He has acted as a peer-reviewer for highly-regarded international journals including Journal of Hydrology, Wind Energy and IEEE Transactions on Power Systems, as well as national expert reviewer for the IPCC report on “Renewable Energy Sources and Climate Change Mitigation” (2010) and the Special Report on 1.5 Degrees Warming (2018). He has acted as external PhD examiner in Ireland and at the University of Auckland and Loughborough University. Paul has also served as Programme Committee member for the 10th, 11th and 12th International Conferences on Environment and Electrical Engineering. He is Associate Editor (Wind Energy) of Renewable & Sustainable Energy Reviews.
Paul is Principal Investigator of the SFI-funded Re-Wind project on repurposing end-of-life wind turbine blades (with Queens University Belfast, Georgia Tech and City University of New York) and the EPA-funded ClimAtt project on tools for extreme weather attribution.
Research Interests: Interests include: renewable energy particularly wind energy, wind turbine blade reuse, energy storage, hydrological impacts of extreme weather events, and greenhouse gas emissions monitoring.
Speech Title: How sustainable are the technologies of the energy transition?
Abstract: Sustainable energy technologies have rapidly advanced in the past two decades. Power from renewable sources has shifted from a niche application to an accepted part of mainstream power generation. For example, there is now over 600 GW of wind capacity installed across the globe. Innovations in materials and manufacturing processes have helped to lower the cost of renewables to make them cost-competitive with fossil fuel sources. These technologies are already huge contributors to mitigation efforts against human-induced climate change.
However, simple carbon accounting is not sufficient to gauge the sustainability of these technologies. There is increasing concern regarding the overall resource footprint of the technologies of the energy transition. Issues such as land-take from wind, hydro and solar developments, environmental impacts and social acceptability of large-scale deployments have emerged as the adoption of these technologies has accelerated. These concerns are exacerbated by the low energy density and temporal variability of wind and solar resources in particular, relative to conventional energy resources.
The issue of sustainable end-of-life solutions for decommissioned renewable energy assets is now emerging. In this talk I will examine in detail the particular case of wind turbine blades. As turbines have a typical operational lifetime of 20-25 years, a large number of wind turbines will be decommissioned in the coming decades. A large volume of composite material from end-of-life blades may enter waste streams if economically feasible, environmentally benign and socially acceptable reuse scenarios are not found. The relative merits of different end-of-life solutions will be discussed, including repurposing, materials recovery, waste-to-energy or landfilling.
