What can “Eindhoven” do?

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)

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

Introduction of Virida

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?

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, 2.925 kWth [2008]

• ORC Tri-O-Gen 150 kWe, 750 kWth [2010]

3. Biomass CHP plant Meerhoven by Municipality Eindhoven

• 1.130 kWe, 5.600 kWth wood chips

4. Heat Grid Meerhoven, 5 small boiler rooms with gas engines by Essent

• 5 times 600 kWe (gas fired CHP)

• App. 3000 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

Energy Infrastructure Assets

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

CHP Eindhoven is “moth-balled”

grids of Essent sold to

Dalkia/PGGM

Closing expected:

1-3-2014

• 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

Example: Existing BEC Cuijk of ESSENT

• Ambitie is om in

samenwerking met bedrijven, kennisinstellingen en overheden een biobased economy park Cuijk te realiseren.

Groene Stroom voor ongeveer 50.000 huishoudens.

Figures from:

11

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

From BEC to BBE park Cuijk

11 Figures from:

• 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”

What can we learn from Cuijk?

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

Case: What can “Eindhoven” do…

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

• 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
