Study reveals how to build a CO2 transport system for Europe

Finally, the plan for the CCS revolution

European plans for CCS (carbon capture and storage) will require a network of 22,000 kilometres of CO2-pipelines to be built across Europe. The construction of this network, which will be able to transport 1200 million tons of CO2 per year by 2050, will cost some €50 billion. This is concluded by an international consortium of companies and research institutions, CO2Europipe, that has conducted a unique in-depth study to find out what it takes to build a European-wide CO2 transport network. According to CO2Europipe, the most important challenge lies in coordinating all the many activities the complex project requires. For this reason it recommends that a small "vanguard" of nations (UK, Germany, Norway, the Netherlands and Poland) take the lead and develop a Master Plan in collaboration with the European Commission.In an interview with EER, Stijn Santen, one of the authors of the report, calls on policymakers to come forward and support CCS. 'Without CCS, fighting climate change will be much more expensive.'

Three hundred “capture points” where over 1 billion metric tons of CO2 are taken out every year and transported through a network of 22,000 kilometres of pipelines to aquifers and depleting gas and oil fields in countries across Europe. This is what the future holds in store if CCS (carbon capture and storage) is developed according to the plans for the European Union. Whether this CCS vision will become reality depends above all on ‘political commitment’, says Stijn Santen, Director of CO2-Net, a specialized consultancy in Rotterdam, in an interview with EER.

Santen is one of the authors of a large EU-funded study that has just been completed by an international group of institutions and companies active in CCS, including Vattenfall, Gasunie, Siemens, RWE and EON. The study looks at what is needed to build a transport infrastructure for large-scale CCS in Europe. At this moment, says Santen – who was responsible for the development of the first CO2 pipeline in the Netherlands near Rotterdam when he worked for Shell some years ago – all eyes are focused on the demonstration CCS-projects that are being carried out at coal-fired power stations in various European countries.

But, says Santen, after this phase has been completed, around 2020, the “real” large-scale CCS-projects will get started – and then the problem of how to transport the much larger amounts of captured CO2 will present itself. Or rather, he says, the transport problem should have been solved by then. ‘By that time, the infrastructure should be in place or the whole programmewill be seriously delayed. And as it can take up to eight years to plan and build a CO2-pipeline, this means we have to start now.’

Master plan

As the study of the CO2Europipe consortium makes clear, building the pipelines that are needed to transport the huge volumes of CO2 that are expected to be captured (some 400 million tons per year in

The technical challenges are the easiest part
2030 and growing to 1200 million tons annually by 2050) will hardly be a piece of cake. Technically, it can be done. Indeed, the technical challenge, says Santen, is the easiest part. The financial hurdle will be more difficult to jump over. But the biggest challenge may be termed ‘organisational’. Think of issues such as: planning and permitting, public acceptance, health and safety standards, operational and CO2 quality standards, adequate regulation, cross-border coordination. These will all have to be addressed before a large CO2 transport system can be built.

For this reason, one of the most pertinent recommendations CO2Europipe gives is for the European Commission and Member States to make a European Master Plan, which would have to be aligned with national plans, and which would set out in detail the steps that will be taken to build the CO2-transport network. ‘A European Master Plan, in combination with national plans, will give all stakeholders the possibility to adjust their own activities to it. And it will give investors confidence to invest in the project’, says Santen. He notes that the intricate gas transport infrastructure that was built in record time in the Netherlands in the 1960swas strongly centrally coordinated. ‘You need this kind of coordination, or you won’t get the necessary investments.’

Key players

What makes the building of a European CO2 pipeline network so complex is that there are a lot of different stakeholders involved – storage operators, power companies, gas transport companies – who all have different concerns and timetables. At the same time, their interests and activities have to be

What makes the building of a European CO2 pipeline network so complex is that there are a lot of different stakeholders involved 
aligned with government plans, regulations and support schemes. An added complexity is that although much of the transport and storage can take place within national borders, nevertheless a significant amount of cross-border capacity will have to be realised between countries with limited storage capabilities and countries that have ample storage capacity. For example, it is expected that CO2-transport will take place from Belgium to the Netherlands, from Poland to Germany, from Sweden, Finland and the Baltic States to the North Sea and from Romania and Hungary to Slovakia. This will require international (EU) coordination.

For this reason, to make the project more manageable, the report recommends that a small group of countries, that have the most to gain from CCS, take the initiative in getting the pipeline projects started. The ‘key players’, according to the report, are Germany and Poland, with their large coal-fired power sectors, and Norway, the UK and The Netherlands, which have extensive gas activities as well as storage capacity. The CO2Europipe study has been limited in any case to North Western and Eastern Europe; South West and Southern Europe were not included.

In principle, Europe has more than enough storage capacity, the report notes. By 2050 the cumulative stored amount of CO2 will be 18 Gigatons (18 billion tons), whereas the estimated available storage capacity is in the order of 300 Gigatons. Some 13 to 25% of the gas field capacity will have been filled

Europe has more than enough storage capacity
and 4 to 5% of the capacity offered by aquifers (saline formations). However, the report does note that these are ‘theoretical capacities’ and that the aquifers that are to contain most of the CO2 have not been explored and tested yet. The researchers recommend that an open database of storage locations will be set up ‘to encourage the CCS industry to explore storage options’. Perhaps even more importantly, the ‘legal qualification’ of the storage capacity should be addressed. The researchers say that ‘a clear legal position’ is needed for the stored CO2, especially for onshore storage.

Business model

An important choice that has to be made in the Master Plans is what “business model” the CO2 transport sector should follow. There are two basic possibilities, says Santen: either transport and storage is vertically integrated into the activities of power companies and other large emitters, or it is developed by standalone companies, that deliver services on the “common carrier” model. According the researchers, the first model is best suited in the early stages of the development, when most of the pipelines simply go from point-to-point. But after 2020, once CCS is introduced on a large scale, the transport networks will become more complex and serve many different emitters simultaneously. In that case the common carrier model will be more suitable.

In the common carrier model, transport contracts would be separated from commodity contracts.Network owners and operators would get ‘a guaranteedreturn on their investments from emitters based on transport fees that are independent of CO2 value and CO2 prices.’ This is essentially how existing gas and power infrastructure companies work, says Santen.

The researchers have analysed the financial results of gas and power infrastructure companies and conclude that they manage to realize ‘attractive returns’ (on average above 15% return on equity and net profit margins between 20 and 30%). The difference of course is that the market for CO2 is an artificial one: it has to be created by government mandate. At this moment, it is the market price for CO2 emissions generated by the EU’s Emission Trading Scheme (ETS) which is supposed to finance CCS, but, as everyone knows, this price is much too low. ‘There is no CCS business case to be made on the basis of current CO2 prices’, says Santen. ‘Additional, ongoing support from the EU and national governments is required.’

Political commitment

In fact, says Santen, government support should not be confined to financial schemes – across-the-board political commitment is crucial to the success of the entire project. ‘For investors’, he says, ‘the biggest risk is the political risk. There will have to be very strong guarantees they will be adequately paid for their efforts. This cannot be dependent on the political mood of the day.’

This commitment will have to come both from the EU and from national governments. Santen is particularly concerned about the latter. ‘At the European level, I see continuing and consistent support. But without clear national commitments, e.g. from the German government, CCS will not

The biggest risk is the political risk 
happen.’Santen says politicians should make a much greater effort to explain to the public why CCS is necessary. ‘They should explain that with CCS, fighting climate change will be much less costly. According to the International Energy Agency, CO2-reduction without CCS will cost $500 billion more.’ He also notes that according to a recent study from the European Climate Foundation (ECF), almost €1,000 billion needs to be invested in new energy infrastructure for the transport of renewable energy if the 80% CO2-reduction target for 2050 is to be met. ‘Compared to this sum, €50 billion for a CO2 transport system is modest.’

Santen notes that for some European countries there are large economic interests at stake. ‘In The Netherlands fossil fuel activities generate huge public revenues: roughly €40 billion a year in all. This is very important to the national economy and to energy security, quite apart from the climate issue. The same goes for countries like Germany and Poland. You cannot expect Poland to close its coal mines just like the Dutchare not going to close down their gas fields. If you want to secure this source of income and wealth, and want to fight climate change, you have to do CCS. Some people think you can do with it renewables only. Germany for example invests heavily in solar and wind power. That’s important, but it won’t be enough, especially now they have decided to phase out nuclear power.’


Some more highlights from the CO2Europipe report

  • The largest effort in the construction of pipelines is expected between 2020 and 2030 since the larger part of the network needs to be in place by 2030. The rate of construction may be as high as 1200 - 1500 km/yr in some regions, 15,000 km in all. In 2030-2050 only some 7,000 km will have to be added.
  • To limit storage to offshore reservoirs (to avoid public acceptance issues with onshore storage) is hardly an option. It would double the average transport distance and increase costs from €50 billion to €80 billion. 
  • Transport by ship will be an optionin the initial phases of projects and to transport CO2 to distant and smaller fields. 
  • As to the health and safety risks associated with the transport and storage of CO2, the report notes there are still a lot of uncertainties. More research on this needs to be done.
  • The cost of building and operating 22,000 kilometres of CO2-pipelines in Europe (onshore and offshore) are estimated at €50 billion. 
  • A final piece of good news: there is a lot of potential demand for CO2 to be used in EOR (enhanced oil - and perhaps gas - recovery) in offshore oil fields in the North Sea. The researchers note that in the USsome 3,000 km of CO2 pipelines have been operational for over 40 years for EOR purposes. Combining CCS and EOR in the North Sea might lead to an additional revenue stream that could greatly help the financing of the pipelines, says the report, although it adds that this will be 'insufficient topay for all CCS costs'.
