Wrap Up
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)
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

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?

Energy Infrastructure Assets
Several assets:
1. Ir Ottobad by Municipality Eindhoven
•
750 kWth (wood chips)
ORC Tongelreep by Municipality Eindhoven
2.
•
•
CHP on Bioline (animal fat)2.350 kWe, 2.925 kWth [2008]
ORC Tri-O-Gen 150 kWe, 750 kWth [2010]
Biomass CHP plant Meerhoven by Municipality Eindhoven
3.
•
1.130 kWe, 5.600 kWth wood chips
Heat Grid Meerhoven, 5 small boiler rooms with gas engines
by Essent
4.
•
•
5 times 600 kWe (gas fired CHP)
App. 3000 household customers (Essent and Municipality)
CHP Eindhoven and Heat Grid by Essent
5.
•
•
•
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
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.

Example: Existing BEC Cuijk of
ESSENT
Groene Stroom voor
ongeveer 50.000
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

Figures
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

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”

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
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
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
