1 What can Eindhoven do? ENERGY CAFE TEAM ENERGY Martijn Wagener, Virida 19th February 2014

2 What can Eindhoven do? Virida Case: introduction Current energy infrastructure Eindhoven Example: from BEC to BBE park Cuijk Case: What can Eindhoven do? Case: Results Wrap Up

3 Introduction of Virida Started in 2013 Activities: Development and feasibility of business cases No Cure No Pay approach on energy savings Services regarding operations (analysis, optimizing, operation) Developing new concepts on Solar and Bioenergy (ZegelsvoorZon, BiomassaContainerUnit, BIOenZON)

4 Introduction of Virida Examples: Engineering Energy Development and subsidy application for Biooil at CHP Eindhoven for Essent Improvement energy infrastructure, Fokker Woensdrecht Quickscan energy savings, Philips Aachen Support Energy Team, TU Delft BioBased Economy Feasibility innovative dryer in Helmond 4

5 Case introduction Eindhoven has: Several energy assets (large CHP, bioenergy plants, heat distribution grids) scattered over town Large CHP 50 MW is mothballed Case question? Q: What can Eindhoven do. to increase sustainable production and to save primary energy? Next: what are some of Eindhoven s Energy Assets?

7 Energy Infrastructure Assets Several assets: 1. Ir Ottobad by Municipality Eindhoven 750 kwth (wood chips) 2. ORC Tongelreep by Municipality Eindhoven CHP on Bioline (animal fat)2.350 kwe, kwth [2008] ORC Tri-O-Gen 150 kwe, 750 kwth [2010] 3. Biomass CHP plant Meerhoven by Municipality Eindhoven kwe, kwth wood chips 4. Heat Grid Meerhoven, 5 small boiler rooms with gas engines by Essent 5 times 600 kwe (gas fired CHP) App household customers (Essent and Municipality) 5. CHP Eindhoven and Heat Grid by Essent 52 MW and > 70 MWth, 3 backup aux boilers 25 MWth each Possibility for bio-oil on gas fired steam boiler of CHP [2014?] Heat Grid customers mainly B2B

8 CHP Eindhoven is moth-balled CHP (52 MW and lot of heat, connect to small heat grid) mothballed. Heat currently generated by 3 large (app. 25 MWth) steam boilers. Heat demand for WKC dropped dramatically Power / Heat ratio in imbalance Spark spread is very low H P GGZ/E CHP Eindhoven Strijp T Strijp S

9 This is the moment. CHP Eindhoven and heat grids of Essent sold to Dalkia/PGGM Closing expected:

10 Example: Existing BEC Cuijk of ESSENT Groene Stroom voor ongeveer huishoudens. Ambitie is om in samenwerking met bedrijven, kennisinstellingen en overheden een biobased economy park Cuijk te realiseren. Wood fuelled Bubbling bed combustion Plant (25 MW) built in 1999 with 10 year MEP subsidy (power only!) Since 2010 moth-balled due to absence of subsidies Vision created (> 40 MWth heat delivery for BBE applications) BBE park Cuijk plan developed 10 Figures

11 From BEC to BBE park Cuijk FASE 0: current bio-energy plant, power-only FASE 1: diversify fuel input FASE 2: expansion in CHP, 2a: steam delivery to existing steam demand 2b: hot water delivery to dryer 2c: integration of innovative digester FASE 3: integration of bio refinery Figures from:

12 What can we learn from Cuijk? Start with a vision. Following a strategy ( path to goal ) Focus on green/biobased brings sustainable business cases Combine value chains (energy-agri-chemical etc.) Increase demand by bringing demand to CHP 12

13 Case: What can Eindhoven do Summary: Eindhoven has. From Cuijk we learned Case question? Q: What can Eindhoven do. to increase sustainable production and to save primary energy? So what is your vision? Following: Discussion of 30 minutes in groups of 5 persons Short presentation by groups Wrapup

14 Vision: Create smart heat grid Eindhoven -> BBE park Eindhoven Create smart heat grid Eindhoven 1. Create a smart Eindhoven heat grid with TPA and huge heat storage Optimize and improve 2. Modify gas fired auxiliary boiler of CHP Eindhoven to bio-oil 3. Improve heat extraction from CHP Eindhoven (lower temp, pressure, more efficiency) Expand heat demand 4. Expand heat demand by connecting new developments such as Brainport Innovatie Campus (BIC), Business Parks together with the Municipality Create BBE park Eindhoven 5. Invest in base load heat demand: digestate dryer connected to heat grid. 6. Develop BBE options such as: flying on manure. Use low cost feedstock and heat to produce jet fuel

15 Wrap-up My solution (2012): create BBE park Eindhoven 2014: Your solutions. new players new chances Several ideas. There is not one good answer we need combination of. Start with a Vision 15
