  1. Responsible Renewable Recyclable Reliable Energy Division Jörgen Persson

  2. A normal facility Carbone dioxide: 150 000 ton/y El consumption: 300 GWh/y Carbone dioxide: 15 000 ton/y

  3. Responsible – Renewable – Recyclable

  4. Low Medium High

  5. Todays District Heating system in Sweden • Approx. 50 % of Heating market • Located in 570 Cities • Approx. 50 TWh total produktion • Turnover of 23 billion SEK • First DH Stockholm • (Sabbatsbergs hospital) in 1878

  6. Heat from accelerator and helium cooling Klystroner Heat: 123 GWh Heliumsystem Heat: 69 GWh Ion source Instrument Heat: 7 GWh Heat: 5 GWh Accelerator Target station Heat: 11 GWh

  7. Linac and cooling system are big consumers Klystroner El totalt: 23 MW El: 10 MW Cooling system Heliumsystem Ion source El: 2 MW El: 1 MW Instrument Accelerator Superconductive cavities Target station El: 2 MW

  8. Renewable produktion • 250 GWh, 130 MW effekt • Approx. 40-50 Windmills, 2,5 MW • Investment app 1 600 – 1 900 MSEK • Green certificate

  9. Sustainable solutions

  10. Responsible – Renewable – Recyclable • Net savings 80 MSEK/y (Revenue green certificate, design parameters) • Surplus heat sale 215 GWh gives app 40 MSEK/y. • Energy inventory app 60 GWh gives app 30 MSEK.

  11. Responsible – Renewable – Recyclable • Saving 165 000 ton carbon dioxide • Save 150 MSEK per year for ESS • International role model

  12. Simulations • District Heating system How do the system cope with the heat load • Klystron Cooling system Different delta P, delta T, High-pressure system, Low, Medium, High • Power station with backup systems UPS, Emergency power, Power quality, Redundancy

  13. Locate and optimize surplus heat temperatures • Optimize the pressure drop in klystrons • Evaluate the dummy load • Design the systems different parameters

  14. Thanks
