BIO-CCUS PROJECTS

AVR Duiven

Feasibility study for CO2 capture from waste toenergy plant

50,000 tCO2/yr

Delivery of CO2 captured to horticulture by truck

Bio-CCUS in the Netherlands

SETTING THE SCENE

Waste to energy plant AVR DuivenMain supplier of district heating network70 MWthWaste (54% bio / sustainable)Paper pulp residu (100% sustainable)Electricity to grid: 125 GWhHeat to grid: 880 TJ (14.000 households)

27 April 20163 | AVR - CO2 capture and liquefaction

SETTING THE SCENE

Approximately 0.2 Mtonnes of fossil CO2 / yearAim to recover 50,000 tCO2/yrSupply the gas to horticulture in the regionalmarketUpscaling towards 2030Improving overall footprint significantly

99,9+%CO2

FLUE GAS

102 000 Nm3/h10% CO2 (dry basis) = 7,6% CO2 (wet basis)Design basis: capture 12 ton/h (full load = 78% capture)

Flex: Operate at 50% and 80% load + Determine maximum throughput

SUMMARY – INDICATIVE NUMBERS

11 | AVR - CO2 capture and liquefaction 27 April 2016

Flue gas conditioning + CO2 capture

Utilities and consumables :Electricity = 17-21 kWh/ton CO2

Cooling water = ~1500-2500 m3/hSteam = 3-4 GJ/ton CO2

MEA to be determined

CAPEX: to be determined
