1 Energy Conversion Parks two examples of clever use of biomass residues in North Brabant Nathalie Márquez Luzardo, Jan Venselaar (Avans hogeschool) and Patrick Reumerman (BTG)

2 Content Background ECP project Concept Different cases Methodology ECP Breda ECP Moerdijk Conclusions / Acknowledgements

3 Background Cleaner (easy) biomass is already valorized. Processes often one-dimensional => tuned to a specific input stream. Flexibility to input and output is missing. Regionally available biomass residues have significant potential, often underutilized. Composition (including unwanted components) and availability may vary (in some cases depending on season). Difficulty finding markets for waste products (sometimes high costs, often to foreign countries). Important transportation costs (energy consumption) => Regional solution is optimal

4 ECP concept

5 5 ECP cases: different starting points Sluiskil: addition to other activities in BioPark Terneuzen Moerdijk: logistics and available biomass processing capacity Breda: coupling to district heating Beerse/Merksplas: current composting organic waste Lommel: localization in Limburg, phytoremediation

6 Methodology

7 ECP Breda starting points Municipality of Breda is the anchor point The municipality wants to be CO 2 neutral in 2044 Objective: Use of local biomass residues within the municipality of Breda for production of sustainable district heating and high quality transport fuels (bio-lng).

8 ECP Breda starting points Exploiting multiple local biomass streams - Cattle and pig manure - Green household waste - Cut-and prunings Several conversion technologies - Anaerobic vergisting, combustion, upgrading biogas to bio-lng - Manure separation outside ECP boundary Application - more sustainable district heating (CO 2 neutral in 2044) - Realizing generation and purchase capacity liquefied biogas (bio- LNG)

12 ECP Moerdijk starting points ECP Moerdijk was developed without concrete anchor point Emphasis from the start on: Using logistic capabilities of Moerdijk Industrial Complex Production of high value products from biomass ECP steps continue until the drafting of the concept

13 ECP Moerdijk starting points Moerdijk is an industrial environment with considerable bio-energy related activities and few residential/ urban biomass. Good logistic connections (e.g. port) Heat supply > demand Gas net is already used to its full capacity.

16 ECP Moerdijk economic evaluation - In financial calculations a biotickets price of 10.7 Euro / GJ is considered. Without the income from biotickets the IRR drops to 4.5%

18 Conclusions Combining technologies is very interesting and results in economic synergies. Uncertain biomass prices and gate fees. Support policies remain crucial. In all ECP cases there is a considerable saving in greenhouse emissions > 90% compared to fossil reference. Cooperation and creating dependencies between the parties is not evident.
