Description

The Rotterdam Capture and Storage Demonstration Project (ROAD) recently completed a report for the Global CCS Institute identifying the opportunities for integrating carbon capture process with the main power generation process and for optimising the efficiency of the power plant and carbon capture unit.

At this webinar, Hette Hylkema, Special Area Manager MPP3 Interface and Andy Read, Director Capture for ROAD Maasvlakte CCS Project C.V., presented the findings of such integration interfaces based on the experience of ROAD, explain major design choices/solutions and discuss the lessons learnt for future CCS projects.

Opportunities for integration of carbon capture process with coal-fired power plants Webinar – 4 February 2014, 1900 AEDT

Hette Hylkema Hette Hylkema is a Project Manager with an excellent understanding of power plant technology and economics. In 2009 he had the lead in the conceptual design of the integration of the 250MW demonstration CCS plant and the Maasvlakte Power Plant Unit 3. He has previously worked on several new build projects, most notably the development of the 225 MW RoCa3 CHP plant, that was built for the delivery of heat and CO2 to a greenhouse area. Hette has over 30 years of experience in the power industry, including design and project development. On the ROAD Project Hette is responsible for the engineering of the interfaces with E.ON’s MPP3 Power Plant (the host for the CCS demonstration).

Dr Andy Read Andy Read is a Project Manager with an excellent understanding of power plant technology and the electricity markets with the associated commercial constraints. For the last five years, he has focused on CCS project development leading projects at Killingholme and Kingsnorth in the UK, and now as Capture Director for the E.ON / GDF SUEZ joint venture at Maasvlakte, Netherlands (ROAD Project). He has previously worked on several new build projects, most notably the early development of the 1275MW Grain CHP plant, and acted as interface between commercial functions (such as Strategy and Trading) and the power plant asset managers. Andy has 20 years of experience in the power industry, including design and operation of supercritical coal power plant, combustion technology and a stint on an operating coal-fired power station. In Andy’s current role, he is one of four directors responsible for the ROAD Project – a 250MW CCS demonstration in Rotterdam, due to be in commercial operation by 2015. He has responsibility for the engineering, design and construction of the Capture Plant including the interfaces with E.ON’s MPP3 Power Plant (the host for the CCS demonstration)

Agenda • Project overview • Main interfaces • • • • Flue Gas tie-ins Steam/condensate supply Electric supply Cooling water • Other interfaces • Operation and emissions • Lessons learned 6 Page 6

State of Play ROAD • Engineering • Detail engineering of capture plant ready • Pipeline route engineered, ‘flow assurance’ study completed • ‘Tie-ins’ (i.a. flue gas, steam) with power plant installed • Permits • Permitting procedures finalized (beginning 2012) • Capture and storage permits are definitive • Publication definitive transport permits soon • Contracts • Capture supplier selected and EPC contract ready to be signed • Negotiations with storage operator (TAQA) on storage progressing well and in final stage • Finance • Very low CO2 prices have caused a financing gap • ROAD, parent companies and other stakeholders are currently working on solution for financial gap ROAD is ready to start construction as soon as financial gap has been solved Page 7

Lessons Learned • Low redundancy and low engineering margins make CCS more economical • Heat integration can save both CAPEX and OPEX • Steam jet boosters may be economical for part load power plant situations to ensure enough pressure for reboiler steam of capture plant • Further heat integration for 100% capture will require external consumers with low temperature demand • Condensate retrieved in Direct Contact Cooler (DCC) can be used as process water in power plant and almost eliminate external fresh water supplies Page 32
