Energy Policycast40 barriers to flexibility – and how to solve them“Anything that exists is possible” as Boulding’s first law prescribes. I was wondering why, in some places of the world, district energy systems were very flexibly integrated with the electricity system – while in other parts, they were not. So I set out to explore the existence of flexible sector coupling.
This resulted in the study that is the focus of today’s episode.
Anyone working with sector coupling and flexibility may benefit from listening in – if they can bear a 30-minute talk by me. Or else, dig directly into the resources referenced below.

2022-04-1432 minEnergy PolicycastHow to fully decarbonise the NordicsA world premiere for your ears!
Nordic Clean Energy Scenarios by Nordic Energy Research is the most comprehensive study of decarbonisation of the Nordics so far – out 7 September 2021.
Energy Policycast is lucky enough to host two of the main authors, Klaus Skytte (CEO, Nordic Energy Research) and Kenneth Karlsson (CEO, Energy Modelling Lab and Senior Project Manager, Swedish Research Institute).
The study explores solution tracks to carbon neutral Nordics through 2030 and onwards to 2050. These tracks include electrification, power-to-X, bioenergy, carbon capture technologies in combination with bioenergy and behavioural change.

2021-06-2902 minEnergy PolicycastCrowdsourced scenicness and acceptance of wind powerHow does the beauty of the landscape, i.e. scenicness, play into the deployment of wind power? And how can we measure scenicness?
Those questions are addressed by Professor Russell McKenna and his co-authors in the study Quantifying the trade-off between cost-efficiency and public acceptance for onshore wind (working paper) and journal paper Scenicness assessment of onshore wind sites with geotagged photographs and impacts on approval and cost-efficiency.
Inspired by the Economist article Computer analysis of what is scenic may help town planners, the researchers applied the scenicness dataset ScenicOrNot to evaluate wind deployment in...
2021-06-0328 minEnergy PolicycastThe hidden sides of wind repoweringWhat happens when old wind projects are replaced with new capacity? Associate professor Lena Kitzing from DTU Wind Energy discuss her recent study - Multifaceted drivers for onshore wind energy repowering and their implications for energy transition - showing previously unknown aspects of repowering. Also worth reading is the affiliated policy brief Multifaceted political and social drivers inform wind energy repowering decisions and potential.
The study was inspired by discussions in IEA's Task 26 on wind and co-authored by Morten Kofoed Jensen/Aegir Insights, Thomas Telsnig/JRC and Eric Lantz/NREL.
In the Peer Review section, w...

Does it make sense economically - and how about climate? This rare and very interesting topic is discussed by PhD Amalia Alonzo and Professor Marie Münster, based in their two studies The climate footprint of imports of combustible waste in systems with high shares of district heating and variable renewable energy and The economic value of imports of combustible waste in systems with high shares of district heating and variable renewable energy. The studies were co-authored with Ciprian Cimpan, Maria Ljunggren Söde...

And what are the consequences of the planning horizon when planning such a system towards 2050?
PhD researcher Juan Gea-Bermudez from DTU Management elaborates these questions in the study Optimal generation and transmission development of the North Sea region: impact of grid architecture and planning horizon. Co-authored with Lise-Lotte Pade, Matti Juhani Koivisto and Hans V. Ravn.
We discuss the projects Promotion, Flex4RES and NSON.
