1 CO 2 transport infrastructure in Germany Necessity and boundary conditions up to 2050 Study by DNV GL Slide 1

2 Goals and tasks of IZ Klima IZ Klima Informationszentrum für CO 2 -Technologien e.v. is engaged in disseminating objective information and pursuing constructive dialogue on the opportunities presented by CO 2 technologies and their potential. We offer our members a communication platform and a vital point of contact for the general public, politicians, the media and industry professionals. Slide 2

3 Our latest publications Newsletter and the latest news on the website Speicherung von CO 2 : Technologie für den Klimaschutz ( CO 2 storage: a technology for climate protection August 2013): brochure introducing the CO 2 technologies and giving an account of the application areas and potentials as well as a selection of international reference projects. Status der internationalen CCS-Entwicklung ( State of the art in international CCS development June 2014): article in Energie für Deutschland, Weltenergierat Deutschland e.v. (World Energy Council Germany) CO 2 -Transportstudie ( CO 2 transportation study ): Model calculations based on the German Federal Government s energy concept: volumes, costs challenges and schedule. Articles in et, Energiewirtschaftliche Tagesfragen, October 2014, and CCJ, Carbon Capture Journal, Jan/Feb Slide 3

4 Aims of the study on CO 2 transport infrastructure in Germany Determine Germany s CO 2 infrastructure needs by 2050: Comparing transportation options: pipeline and ship Technical demands, sizing, costing Identify the timeframe for building the CO 2 infrastructure and the key factors: Lead-in time Regulatory requirements Background to the analysis: how to determine Germany s CCS needs: Projecting CO 2 emissions in Germany up to 2050 Embracing the consequences of the German government s Energy Concept Slide 4

5 Study shows: CCS must remove 60 million tonnes of CO 2 Starting point of the analysis: German government s 2010 Energy Concept CO 2 emission trends up to 2050, taking into consideration the reduction targets Examination of major emission sources in power generation and in industry (> 0.5 Mt/a CO 2 ) CO 2 volumes to be captured and transported CO 2 volumes (Mt/a) Year CCS technology can be deployed to close the gap between targeted and actual CO 2 emissions (60 Mt per year by 2050). Slide 5

6 Cluster analysis as a tool for sizing: CO 2 output profiles of clusters with data for the necessary CO 2 flow rates: Mass flow (kg/s) Time - one week (day number, hour) Cluster I: Cluster II: Cluster III: high concentration of sources in industrial and power sources centralised power generation only scattered industrial and power sources Cluster with different CO 2 sources guarantees higher utilisation of the infrastructure Utilisation rate of cluster: % Slide 6

7 Transport options for CO 2 storage on this scale Collection Source Onshore pipeline Offshore pipeline network Storage site Pipeline network Pipeline network, on- and offshore (50 km of collecting pipelines) Collection Source Barges Tankers network Storage site Barge/Tanker transport Barges for inland waterways, tankers for offshore transport Slide 7

8 Size and capacity of a CO 2 transport infrastructure*: Pipeline transport: 60 Mt/a corresponds to four 24'' to 32" pipes 350 km onshore and 100 km offshore Transport by ship: 110 barges (8,000 t) for 350 km 16 tankers (30,000 t) for offshore Challenge: composition of the captured CO 2 (secondary constituents) Shipping demands intermediate storage, but offers more flexibility than pipeline transport * Examples calculated on the basis of 60 Mt CO 2 Slide 8

9 Economic viability and implementation capital expenditure Investment in pipeline network Investment in barge and tanker network Capital expenditure in m Capital expenditure in m Investment in CO 2 infrastructure for both transport options is roughly equal. Additional investment will be needed in capture plants and storage sites. Slide 9

10 Timeframe demands that policymakers set the CCS agenda now First demonstration plants CO 2 feed-in of first commercial plants Wide-scale commercial use Create regulatory requirements Licensing procedures Construction phase Re-launch the CCS debate Early and continuous public participation / licensing management Communication support through the construction phase and project Early and continuous public participation to create understanding and an enabling environment for the necessary infrastructure Slide 10

11 Conclusions The new study shows: Additional measures to reduce emissions are strongly needed if we are to achieve the climate targets: By 2050 the gap in Germany will grow to 60 million t of CO 2 per year. The storage capacities under the German North Sea offer an alternative to onshore storage. The technical feasibility of CO 2 transportation to the storage sites under the German North Sea is not a limiting factor. Action must be taken now to create the necessary infrastructure for a widescale introduction of commercial plants by Slide 11

12 Outlook and need for action The emission reduction targets cannot be reached only by improving efficiency and expanding renewable sources. CCS technology presents an opportunity to avoid the emissions from power generation and industrial processes in line with European climate targets. If CCS is to be deployed as part of an effective European climate change strategy, policymakers must take action now. The most urgent step is to set out the right framework in which the necessary transport infrastructure can be provided. There must be constructive dialogue with the public and policymakers to explain in an objective way the challenges and opportunities presented by CCS for Europe and to provide answers to whatever questions people have.
