[EA5] Integrated solutions for electrification: three approaches from three countries

The path to a climate-neutral Europe in 2050 will be paved with a variety of solutions. Diverse conditions in European countries require holistic planning approaches tailored to local needs to progress towards a net-zero power system. In the fifth webinar of the Electrification Academy, we present three integrated approaches from different countries. All these strategies seek synergies between different solutions to meet the common challenge of integrating growing shares of variable renewable energy sources, boosting power system flexibility and lowering carbon emissions.

Questions raised during the webinar dd April 28, 2021

  1. I think there are examples of distribution level markets for flexibility. Has this changed the strategy for district heating management?  Can the heating flexibility participate in a local market and also watch for opportunities in the wholesale market?
  2. Very interesting presentation on Denmark, but I think that Denmark is in a priviliged position as it is surrounded with countries with a large hydro power capacity. Belgium is not that lucky and I think that we have to rely on thermal power capacity (based on decarbonised fuels) to realise the decarbonisation of our country. If so cogeneration might be a preferred concept. Any thoughts about my reasoning?
  3. ESO — what’s the acronym?
    • Electricity System Operator
  4. For the presentation about Denmark, Is it really possible for district heating to be cheaper that individual heating, in case both of them use heat pump?
  5. Interesting UK project - did you test with customers, or did the analysis not involve customers (meaning, indications that for example dynamic TOU tariff + incentives + smart controls had good BC results was based on assumptions, not on test data)?
    • Smart storage heating control projects in GB have shown consumer energy bill reductions of on average 20%, but this is over a range of -40% to +5% since it varies by customer. A project is ongoing in Glasgow to cover 10k flats based on smart controls that can be dynamically controlled, typically three times per day dependent on weather, room tempearture and individual needs.
  6. Who do you think will drive the practical roll-out of the 4D curtailed wind project? The ESO? The DSO? Scottish Government? Energy Suppliers? We have the smart charging controls for retrofit but it is not clear which party will take the lead.
  7. What about the efficiency when using H2 instead of natural gaz in case of retrofit?
  8. Given that we can use so much more volatile generation with the flexibility of the existing heating system (see Christian's presentation), and need so much synthetic hydrocarbons for mobile applications and the chemical industry, when might we have surplus to burn in CHP?
  9. Interesting presentation on H2 CHP ! On the City of Esslingen case: what is the load of the electrolyser? Is it enough to pay off?
  10. Scotland: reported CO2 emission reduction potential seem to be way too high. UK total GHG emissions are in the order of 455 MtCO2-eq. So reporting several tens of GtCO2 savings is impossible (global energy related CO2 emissions were 33 GtCO2).
  11. There’s also solar district heating, would love to hear from them at a later point: https://www.solar-district-heating.eu.
