1. Cluster Technology of Wallonia Energy, Environment and sustainable Development 1 TWEED Cluster Presentation Michael Corhay 6th October 2011

2. … 2 "The sustainable cluster in Wallonia and Brussels"

3. Cluster Technology of Wallonia Energy, Environment and sustainable Development 3 Biomass actors within TWEED (examples)

4. - Example of Walloon Companies 4 XYLOWATT Gasification CHP Plant Global efficiency = 75% (25% electricity, 50% heat) Global efficiency = 75% (25% electricity, 50% heat) (Combined Heat & Power 0,1–10 MWe) www.xylowatt.be Power Production Technologies

5. The NOTAR ® downdraft gasifier Wood is composed of 52% C + 6% H + 41% O + 1% ashes PYROLYSIS Wood is decomposed in charcoal (30%) and pyrolysis gas (70%) COMBUSTION Pyrolysis gas (composed mainly of heavy tars) are burned and cracked with air to produce CO2 & H2O at high temperature (1200°C) REDUCTION Exhaust gases react with the carbon of the charcoal to form the fuel gas: CO2 + C = 2 CO et H2O + C = H2 + CO Power Production Technologies

6. GreenWatt -from the feasibility study to the construction and start-up of the installations, turnkey projects -developed an innovative biomethanation technology; Unlike traditional technologies, this technology – called two-stage – enables energy production at a local scale on the basis of plant residues without any need for external contribution (liquid manure, etc.). -offers a simple, efficient solution for purifying the COD-laden water evacuated by the food-processing industry. 6 FAD (Flushing Anaerobic Digestor), developped by GreenWatt is an original design of a digestor (methaniser) with high yield incorporating a system of unpatching and renewing of the biofilm. Walloon Technology, Patented www.greenwatt.be Biomethanation Technologies - Example of Walloon Companies

7. 7 - Building of an industrial treatment unit ( endive roots) Electricity production - (80 kWe 24/24 ) and heat production (94 kWth for 15 tons of waste a day). Biomethanation Technologies - Example of Walloon Companies

8. De Smet Engineering & Contractors Funded in 1990 by Groupe De Smet General contracting company specialized in the agro- industrial field ( sugar industries, edible oil, etc.) Supplier of industrial equipments Project management In 2004, DSEC made its general-contracting know-how available in other fields, including bio-energy and agro- chemical sectors (bioethanol/biodiesel). Turnover 120M€ More than 100 employees On 5 continents 450.000 m³ yearly building capacity www.dsengineers.com Biofuel - Bioethanol/Biodiesel - Example of Walloon Companies

9. Pellets Humidity Rate between 6 and 12 % NCV 5 kWh/kg Biocoal (Biochar) Humidity Rate between 3 % NCV 6,7-7 kwh/kg Wood chips Humidity Rate between 20 and 30 % NCV 3,5 kWh/kg Coal NCV 7,5-9 kWh/kg Biofuel - Biocoal

10. CMI- NESA - Technology supplier - Supplies and develops wood torrefaction equipments Biocoal Technology Supplier - Example of Walloon Companies

11. Project Bema SynCap has initiated a renewable energy and bio-tech project aiming at the production of: - Bio-energy (diesel) from microalgae (BEMA) and - Molecules with high added value. The BEMA project’s major objective is to implement a prototype photo-bioreactor that can demonstrate the feasibility of large scale microalgae biomass production. www.syncap.eu Biofuel from algae - Example of Walloon Projects

12. Cluster Technology of Wallonia Energy, Environment and sustainable Development 12 Biomass Project in Sub-tropical countries (Sénégal)

13. The PEC project Biomass Project in Senegal « Projet PEC » – Large Scale Wood Energy plantation & Electricity Production Phase I: Wood Energy Plantation 1100 hectares Phase II: Building and Exploitation Biomass Power Station 3 MW 2007 – 2009 OK 2010 – 13

14. Biomass production in Casamance Context: -Favorable climate (tropical), pluviometry > 1250 mm Biomass Project in Senegal

15. Context micro: - Fast-growing trees (turnover 3-7 years) (Eucalyptus, Acacia) - Growth (productivity): 15 to 20 tonnes of dry biomass per hectare par year (1500-2000 trees per hectare) - Large area of unused land (contract partnership with the local people) - cheap and available local labour Cheap biomass production (fuel for power station ) Biomass Project in Senegal

16. Context micro: - Wood production cost: 35 € per ton - Woodfuel (MWh): 7-8 €/MWh!  Heavy fuel 35-40 euros/Mwh! - Sustainable management of plantations - 1000 hectares - Around 18.000 tons of dry biomass Enough wood for a 3MW power unit

17. Power Production 17 -From Wood to Power Technical Diagram Investment: 3M€/MW installed
