CSLF Ministerial in the United Arab Emirates

TD 2The Carbon Sequestration Leadership Forum (CSLF) meetings in Abu Dhabi, UAE, were held from 4-6 December and concluded with the 7th CSLF Ministerial Meeting. The CSLF is a government-to-government agreement on developing CCS, it started in 2003 and now has 25 member countries and the European Commission, and consists of a Technical Group, a Policy Group, and Ministerial meetings.

The Ministers and other heads-of-delegation agreed a Ministerial Communique “Advancing the Business Case for CCUS”. This agreed key actions to progress CCS as follows:

  • Ensure CCUS is supported as part of a suite of clean energy technologies in clean energy policies
  • Leverage the success of operational projects while emphasizing the urgency of developing new projects, noting the opportunities on industrial processes
  • Development of regional strategies to strengthen the business case, including for governments to support infrastructure onshore and offshore.
  • To explore new utilisation concepts beyond CO2-EOR.
  • Collaborative R&D on next generation CCUS technologies for power and industry, including under Mission Innovation.
  • Expand stakeholder engagement and strengthen links with other global clean energy efforts, including Mission Innovation, Clean Energy Ministerial, IEA, and the IEAGHG.
  • Increase global shared learnings and disseminating best practices from CCUS projects and strengthen coordination on R&D globally, including for offshore.
  • Continue to engage the public on CCUS.

20171206 150555As well as updates on CCUS developments for the region and globally, the Ministerial Meeting included a session on CCUS infrastructure, where John Gale presented IEAGHG work on the business models for CCUS hubs and clusters.

The CSLF Policy Group endorsed one new project as recommended by the Technical Group: the CO2CRC Otway Stage 3. Japan, on behalf of the Regulatory Task Force, presented the report and conclusions on “Practical Regulations and Permitting” based upon learnings from seven project case-studies (Japan led this Task Force and IEAGHG was one of the supporting co-authors).

The CSLF Technical Group presented an updated “2017 Technology Roadmap”. This report provides a good review of technology progress and needs (it will be summarised by IEAGHG in an Information Paper). Norway, on behalf of the Offshore CO2-EOR Task Force, presented its report and conclusions on the potential for CO2-EOR offshore and how to progress it (IEAGHG will produce an Information Paper on it also). IEAGHG were co-authors to both these reports. Updates were given from other Task Forces: BioCCS; Improved Pore-space Utilisation; and Industrial CCS. The CSLF Technical Group agreed to start a new Task Force on hydrogen and CCS, and is considering a new task force on mineralisation. IEAGHG’s work will be relevant to both of these.

The International CCS Knowledge Centre presented a review of their recent Global CCS Symposium, which had focused on the good news and positive developments and learnings from operational projects. In contrast, there was an interesting presentation by the Netherlands on lessons from the ROAD project not proceeding.

IEAGHG presented an update on its activities and how its work has been used recently to inform UNFCCC at COP-23, the London Convention, and IPCC. IEAGHG also presented the outcomes of the 2nd Workshop on Offshore CO2 Storage (see IEAGHG report 2017-TR12 and earlier blog in July). This included the background of this work and how the results have been used to inform the London Convention and UNFCCC. The offshore idea was first presented to CSLF in 2013 by the Bureau of Economic Geology at the University of Texas. The CSLF created an Offshore Task Force led by the US DOE, which reported at the CSLF Ministerial in 2015. This report and the two workshops on offshore subsequently hosted by the University of Texas, have stimulated new sharings between countries and new countries to be interested in CCS and for these to also use UNFCCC Technology Mechanism funds for the first time. The US DOE has now very recently announced two new projects to develop offshore CCS in the Gulf of Mexico. So overall a success story for CSLF Technical Group work being used and creating positive impacts. This good news story was included by the chair of the Technical Group in her message to the CSLF Policy Group and to the CSLF Ministerial.

IEAGHG participates directly in the CSLF through an Agreement with the CSLF Technical Group, and frequently contributes in its Task Forces.

This was a very well attended CSLF Ministerial, chaired by the new US Secretary of Energy Rick Perry, with Ministers from the hosts UAE and Saudi Arabia, plus several Deputy-Ministers and senior civil servants. Compliments to the hosts, the Ministry of Energy of the United Arab Emirates for a very impressive set of CSLF meetings.

End of COP-23

New TD 2There will be much analysis into the details coming out of COP-23, but my short summary is as follows.

Progress was made in general in the details of the ‘rulebook’ for the Paris Agreement, but there is a lot of work still to do. As a result it is suggested there may need to be an extra UNFCCC Parties meeting before COP-24 in order to be ready at COP-24. A Decision text was produced as the high-level agreements out of COP-23, called “Fiji Momentum for Implementation”. Of note is that, as well as encouraging urgency in developing the Paris ‘rulebook’ for post 2020 implementation, it puts an emphasis on undertaking and reporting pre-2020 ambitions and funding, by implication by developed countries. In the same context, this Decision urges countries to complete ratification of the “Doha amendment” which was an extension of the Kyoto Protocol from 2013 to 2020 (ie filling in the gap before the Paris Agreement starts). This Decision sets up the facilitated dialogue, now known as the “Talanoa dialogue” to be undertaken during 2018 to undertake a stocktake of pledges and progress to date to be reported at COP-24.

What is lacking from this Decision is any mention of oceans. From a scientific perspective this is disappointing given the importance and interdependence of oceans and atmosphere in climate change and impacts on oceans of CO2, and given the theme of the COP by Fiji on oceans, resulting in a great number of side-events and initiatives on oceans (including our UNFCCC Side-event). Well at least the relevant ocean science got good exposure in the COP, and hopefully this will continue.

Also of note from COP-23 was the “Powering Past Coal Alliance”. This was an agreement outside the formal UNFCCC processes by some 19 countries and several US states and Canadian provinces to phase out “traditional” coal power by 2030 in OECD/EU and by 2050 in the rest of the world. By traditional, they mean unabated. Specifically they call for no new build or funding for such unless built with operational CCS. These countries included UK, Canada, France and the Netherlands, but not heavy coal users such as USA, Germany, Poland, Australia, China and India. As I mentioned in my previous blog, there were many side-events around encouraging the move away from coal power. 

So a work-in-progress COP and we look forward to seeing more progress in the details in 2018, perhaps with an extra SBSTA meeting, and to countries not overlooking their pre-2020 ambitions as they look to their future pledges under the Paris Agreement.  COP-24 will be in Katowice, Poland.

A review of COP-23 will be provided by IEAGHG webinar soon.

Second ECRA/CEMCAP Workshop - CCS in the Cement Industry

Monica - BlogCEMCAP held its second ECRA/CEMCAP workshop in Dusseldorf, Germany, on the 7th November. CEMCAP is a collaborative project funded by the H2020 program which aims to increase the TRL of carbon capture systems applied to the cement industry and decrease the costs associated. Within the innovative concepts under development, we can find new construction and retrofitting of cement plants with post-combustion (chilled ammonia, membrane-based and calcium looping technologies) and oxyfuel systems. The approach of this consortium is not only experimental but also based on modelling to optimize the operation conditions and show transparent techno-economic information. In addition to full capture, partial capture is considered as an alternative configuration, which could be beneficial at specific conditions. 

This event was a great opportunity to see updates on advanced carbon capture technologies applied to the cement industry. As shown by Norcem Brevik, where 4 different technologies are being tested (RTI absorbent, NTNU/Air Products membrane, Aker Solutions amine and Alstom Power calcium looping), CCS is technically feasible but must be economically supported.  

Within the CEMCAP overview, TNO opened interesting discussions regarding CO2 utilization to increase the revenue. Although at lower rate than the use of CO2 for EOR or the invested CO2 in storage, this option was shown as an available alternative to keep in mind. Contrary to the basis scenario, TNO presented the possibility to reuse part of the CO2, in combination with storage and/or reuse part of the CO2 stored.

In addition, the LEILAC project gave a presentation about their Direct Separation technology, which will be tested at the Heidelberg Cement plant in Belgium. The pilot plant is expected to start operations late next year after reaching the final investment decision (FID) in August. Moreover, following the contribution on the calcium looping system, Politecnico de Milano also presented their recently started H2020 project CLEANKER.

As conclusion from this workshop, we saw great interest from academia and industry (developers, suppliers and cement producers) on CCS applied on cement production. It is essential to reduce CO2 emissions in the industry context to reach the decarbonized scenarios and cement is one of the main emitter industries. In this line, we can see several projects running and including several technologies, which exhibits the international interest on cutting emissions in the cement sector. While few systems are at an advanced TRL, others need to be tested but exhibit a great integration potential.

IEAGHG has, in the past, studied CCS technologies applied to the cement sector (as included in  http://ieaghg.org/docs/General_Docs/Reports/2013-19.pdf) and we will soon deliver an updated techno-economic review, carried out together with our colleagues at the IEA.

IEAGHG at COP-23. End of week one

New TD 2On Saturday we reached the end of the first week of COP-23, which is meeting in Bonn from 6 to 17 November. Whilst physically in Bonn, the formal host is Fiji, the first time a small island state has presided over a COP. Fiji asked that a focus of this COP to be on oceans, and we responded in our UNFCCC Side-event on the 7th November (see earlier blog).

The focus of the negotiations at COP-23 is to make progress on the implementation of the Paris Agreement ready for the post 2020 climate regime. The adoption of an implementation ‘rulebook’ for the Paris Agreement is due to be completed at COP-24 in 2018. A ‘facilitated dialogue’ is being prepared to undertake a stocktake of progress and pledges at COP-24 also. At half way through COP, the process ‘stocktake’ by the presidency concluded there was progress in most areas needed. We are particularly interested in the technology aspects (under Article 10 of the Paris Agreement) and we await to see the outputs of these. There appears to be technology neutrality and encouragement of collaborative R,D&D in the discussions (which encourages our activities) as well as links to funding mechanisms. A draft ‘technology framework’ may be presented at SBSTA-48 in April 2018.

The COP is split into two sites, one for negotiations and one for side events and exhibits. There is concern that this separation reduces the ability of the side events to inform 13 11 17  COP23 IMG 31negotiators with the latest science and developments, the logistics are not conducive to moving between meetings in different zones (I found hiring a bike or the electric taxis to be the fastest way). However at our UNFCCC Side-event we were fortunate to attract a healthy number of country delegates.

In the other side events, there were several that I saw around encouragement of a move away from coal. Their messages on whether abated or unabated coal seem confused at times. I saw one of these criticise CCS as too expensive and as having a smaller role in achieving 1.5C, which is different to what is shown in IEA’s ETP 2017 scenario which I pointed out.

Also of note was the unofficial American pavilion, which brought in several Senators, City Mayors and business leaders such as from Microsoft, Mars and Walmart.

In the first week there were several other side events on CCS as well as our UNFCCC Side-event. An interesting one was held in the China Pavilion on the 8th, organised by NDRC, GCCSI and ADB. Several speakers presented China’s CCUS outlook. China plans to have CCUS contributing 10-15% of its emissions reductions by 2050. It was suggested that capturing CO2 from coal chemical plant is a cost effective way for China to deploy large scale CCS projects. China is also preparing for implementation of two large-scale integrated CCS projects in coal-fired power plant. Five CO2-EOR projects are underway to test the efficiency of CO2 flooding in China, and EOR could be a driver for CCUS in China. Presentations also included updates from the IEA, Norway, UK and the International CCS Knowledge Centre. This was well attended, maybe around 50 attendees.

13 11 12 COP23 IMG 2989In terms of IEAGHG involvement at COP-23, as well as our main Side-event, we helped organise and co-chair an event on CCUS in the EU in the EU Pavilion. The organisation was led by CO2GeoNet, with CCSA, GCCSI and Bellona. A presentation from ZEP showed that CCS is indispensable for the EU reaching its climate targets, particularly when levelised system costs are considered, and the significant role of ambient heat as a renewable resource in the ZEP analysis. The event also show cased cement industry and Norwegian achievements. A Norwegian trade union representative said “there are no jobs on a dead planet”. In addition, IEAGHG presented at an event on the need for CO2 storage, organised by CO2Geonet and hosted in the Energies2050 pavilion. IEAGHG was also asked to speak at an ocean science event “Ocean options: Climate challenges and science responses” in the UK pavilion on 8th. This was well attended for the room size, maybe 40 people. This event covered an update on climate impacts of heating and acidification on the oceans, and responses in terms of blue carbon and IEAGHG presented on marine monitoring arising from CCS work, and in particular the UK and EU work by STEMM-CCS and ETI’s AUV. IEAGHG also contributed to a booth with the University of Texas, Bellona and CCSA, which proved to be well located and very popular at key times.

I also followed updates from the CTCN and the Green Climate Fund. CCS is an eligible technology under both.

Despite the grey and wet weather outside, there was a warm atmosphere of hard work inside COP-23. We will see what progress is made under all the negotiation streams towards the implementation of the Paris Agreement.

COP-23 Side-event on CCS and Oceans and Small Island States

TD 2Yesterday was our Side-event, co-organised with The University of Texas, Bellona and CCSA. It was well attended, with around 150 attendees, and lots of good questions.

The side event started with Dr Carol Turley OBE presenting an update on ocean acidification and its significant impacts on the planet; even the NDCs pledged so far will still cause a very high risk to marine ecosystems such as warm water coral reefs, and hence why we need to stop putting CO2 in the atmosphere and to start removing it. Of course, CCS technologies help do this CO2 reduction, and I explained how the London Convention responded in 2006 to the very real impacts of ocean acidification by amending itself to allow CO2 geological storage offshore, with appropriate regulatory guidance to protect the marine environment.

Dr David Alexander of the University of Trinidad and Tobago presented on the climate impacts already happening there and the considerable potential for CCS they have from TD IMG 4663 08 11 17their ammonia and LNG production. The best CO2 storage potential exists in depleting oil and gas fields and saline formations offshore. Dr Alexander is an IEAGHG Summer School alumni from 2009.

Dr Katherine Romanak presented on the learnings from US DOE projects in developing monitoring for CO2 storage, now taking it from onshore to offshore. “We know CCS works, and we know how to show it works”.

Mike Monea presented an update from Boundary Dam project knowledge sharing. Vice-Mayor Geir Lippestad presented Olso’s plans to reduce GHG emissions from waste using CO2 capture. Keith Whirisky of Bellona presented on the need for infrastructure development to join up industrial sources to storage. Finally, thinking about encouraging renewables, Clara Heuberger of Imperial College presented from a system perspective on CCS supports renewables, an area needing more recognition.

Questions ranged from the more technical aspects of flexible CCS in energy systems and Trinidad and Tobago’s CCS potential, to basic principles around waste reduction options.

Overall, the session showed why the oceans need CCS, and how it can be done in the perspective of small island states who need to move beyond their first NDCs to decarbonise their industrial sources. This will be increasingly important as NDCs are updated and as countries submit their long-term GHG mitigation strategies.

Many thanks to all who participated, especially the audience.

CO2STCAP- Partial Capture on Industrial Sources

Monica - Blog18 10 17 Mon CakeAs part of the CO2STCAP project, last week I went to the review meeting in Stockholm. Concurring with this, the 4th October was the Cinnamon Buns Day in Sweden and we celebrated both, the last advances on the project and such a nice local pastry.


This project, funded by the CLIMIT program, Swedish Energy Agency and participant partners, is coordinated by Tel-Tek and counts with the presence of 11 partners (Chalmers, Telemark University College, Norcem, Elkem, GCCSI, Swerea Mefos, RISE Bioeconomy, SSAB, AGA Linde and IEAGHG).

The objective of this initiative is to apply partial CO2 capture to the most emitting industries to obtain more cost-effective solutions to reduce carbon emissions in steel& Iron, cement, pulp& paper and metallurgical production of silicon for solar cells. As interesting approach, the consortium is working on their cost assessment, developed by Tel-Tek, together with experimental tests and modelling tasks, supported by the rest of the partners.

During one day full of presentations, we saw the project updates and discussed on the next steps. As highlights, this project is proposing novel ideas and the interface with the cost tool is fascinating.

Regarding the cement industry, a presentation based on the Norcem case was given by Tel-Tek.  With 33MW as waste heat available in the process, four cases have been studied, which will be reported in the coming months.

18 10 17 Mon Attend

Four different full capture scenarios have been studied for the steel&iron production. Based on the results from the different simulation models constructed, we had an interesting discussion on the following partial capture cases.  

Within the results from the pulp& paper industry, we saw one study on the optimization of the capture configuration and the sensitivity analysis to clarify the influence of the assumptions on the results. Operating hours, lifetime and OPEX are the most influencing ones. As one of the conclusions from this presentation, CO2 capture applied to the pulp&paper sector is a cheap solution compared to other industries

During the next period, other configurations will be studied to minimize the cost of CO2 Capture in those industries and the use of biomass will be explored. We are looking forward to attending the next meeting

For more information about the project, there was a recent article published within the framework of GHGT-13: http://www.sciencedirect.com/science/article/pii/S1876610217319690

Progress on Ratification of the London Convention’s Export Amendment for CCS

TD 2It is the 39th meeting of the London Convention and the 12th meeting of the London Protocol this week, the global treaties that protect the marine environment. The detailed work on transboundary CCS was completed in 2012 (see IEAGHG 2013-IP26 and 2014-IP19) but outstanding is the ratification of the 2009 amendment for CO2 export which would remove a barrier to transboundary CO2 storage projects offshore. Whilst the 2009 export amendment was adopted in 2009, two thirds of the 49 Parties to the London Protocol need to ratify the amendment for it to come into force (ie 32). So in terms of ratification progress, new at this meeting was the announcement that Iran and Finland had ratified. Previously, Norway, UK and Netherlands had ratified, but no other countries in recent years. So it is welcome that there is progress, but still very slow towards it coming into force.

IEAGHG gave an update on activities relating to offshore CCS, and Norway gave an update on the progress with developments towards a full-scale industrial CCS project, which would have the potential to receive CO2 from industrial projects across Europe and so would benefit from the export amendment coming into force.

Global CCS Symposium at Regina

New TD 2The International CCS Knowledge Centre held its first Global CCS Symposium with a theme of “Advancing a Path Forward”, supporting the goal of the Centre to advance CCS globally. Some 160 attendees from 11 countries participated, including from China, Mexico, Indonesia, Bangladesh, South Africa, and from India by video, as well as Norway, Australia, UK, and from Asian Development Bank and World Bank.

The symposium brought together coverage of technical aspects in capture and storage, application in power and industrial sources, economics, policy aspects, climate-need aspects, CCS in the Paris Agreement, and perspectives from developing countries including much from China, and also Indonesia, Vietnam, Bangladesh and India.

There was a common recognition in the need and challenges in going from the million tonnes scale now to the gigatonne scale. Mike Marsh CEO of SaskPower gave an update on Boundary Dam CCS Project (BD3). David Greeson of NRG gave an update on the Petra Nova project. Brent Jacobs and Corwyn Bruce provided updates and learnings from BD3 operational experience, for example the use of activated carbon to stop foaming of the amine, and the benefits of testing capture systems in flexible operation load-following conditions, and differences to Petra Nova in construction materials for the absorber. Experiences from Shell’s Quest were also shared. Mona Molnvik of SINTEF gave an update on Norwegian developments, including the news that Shell and Total were joining Statoil in development of the Smeaheia storage site. ADB described their CCS technical assistance projects, which are to be extended from China and Indonesia to India, Vietnam, Kazakhstan and Bangladesh, including an interest in capture-ready regulations (for which IEAGHG has its 2007 report).

The Saskachewan Minister for Environment the Honourable Dustin Duncan spoke and described CCS as a “Saskachewan success”. Several media attended, interviewed and reported on the event.

IEAGHG was involved in moderating an ‘armchair dialog’ on “CCS: Essential Now!”, drawing upon IEA ETP 2017, IPCC and personal experiences and views of the panel.

The presentations will be made available by the Knowledge Centre. The symposium was followed by a visit to Boundary Dam, Aquistore and CCTF. Overall there was an air of positivity in the symposium, from the sharing of learnings from the large-scale operational projects with an international audience, including with some new countries.

Mission Innovation CCUS workshop, Houston, Texas

TD 2Jasmin crop

Mission Innovation (MI) is an international initiative seeking to double each government’s investments in clean energy research and development over the next five years, with the goal of accelerating the pace of technology innovation to meet economic competitiveness, environmental, and energy security demands. It is estimated that the clean energy baseline doubling would make available an additional $25 to $35 billion in clean energy R&D, on top of a business-as-usual baseline investment of about $75 billion over 5 years. New investment will be focused on transformational clean energy technology innovations that can be scaled to varying economic and energy market conditions. Mission Innovation consists of the following Innovation Challenges (ICs):

  • Smart Grids
  • Off-Grid Access to Electricity
  • Carbon Capture
  • Sustainable Biofuels
  • Converting Sunlight
  • Clean Energy Materials
  • Affordable Heating & Cooling of Buildings

The goal of the Carbon Capture IC, which is led by the USA and Saudi Arabia, is to identify Priority Research Directions (PRDs) that will lead to breakthrough technologies. This workshop covers three major themes centred on carbon capture, utilization and storage (CCUS). The workshop focuses on identifying breakthrough low technology readiness level (TRL) research directions, i.e. TRLs 1-3/4, that are needed to achieve long-term technologies for CCUS. 

The product of the workshop is a report that will be issued. The report has two high level purposes:

  • Inspire the global research community to develop breakthrough research concepts.
  • Convince the general readership, including governmental policy and funding decision makers, that these research directions are critical to meeting future global energy needs.

Some 240 experts from 22 countries attended the workshop in Houston. Work was carried out in teams in the following focus areas:

  • CO2 capture
    • Solvents
    • Sorbents and looping systems
    • Membranes
    • Combustion and other technologies
  • CO2 utilization
    • Thermochemical conversion and hydrogenation of CO2
    • Electrochemical and photochemical conversion of CO2
    • CO2 conversion to solid carbonates
    • Biological conversion of CO2
  • CO2 storage
    • Injectivity and capacity
    • Monitoring, verification and performance metrics
    • Forecasting and managing induced seismicity
    • Well diagnostics
  • Crosscut

Crosscut was not broken down into panels but followed the developments in the other panels and produced nine PRDs itself, providing some reality-tests at the systems level for the other topics. 

A total of 33 PRDs were identified and described by the teams. These will be written up into the final report.

At the workshop, IEAGHG input directly to the “Crosscut” and ”CO2 storage: Monitoring, verification and performance metrics” panels. We look forward to seeing and using the results of the workshop.

NetPower Visit

TD 2As part of the Mission Innovation CCUS workshop in Houston, we visited the Net Power project at La Porte. This is a pilot-scale demonstration of a novel direct-fired oxy-fired supercritical-CO2 gas turbine based on the Allam Cycle. In fact Rodney Allam himself was present and co-hosted the visit with Bill Brown the CEO of Net Power. The partners in this project are 8 Rivers, Exelon, and CB&I. We learned that the combustion chamber is scaled at 50 MWth, and the turbine at 200 MWth and it is a first-of-a-kind by Toshiba. The inputs will be mostly CO2, some O2 and a small amount of CH4. A significant feature is the recycling of heat and CO2, and the production of water (when air-cooled), N2, Argon and CO2. The result is hoped to be an economical gas turbine with low cost electricity and a high-pressure supercritical CO2 stream output ready for pipeline transmission. The pilot project is at an advanced stage of construction. The expectation is testing of the combustion chamber in Q4 2017, and full operation in Q1 2018 with grid connection. The O2 and CO2 is supplied by Air Liquide nearby. The next phase will then be a 500MWth scale up of the turbine, and no scale up required for the combustors, and engineering design is underway. If successful, the technology offers a number of advantages over conventional plant: inherent CO2 capture, no NOx emissions, smaller physical footprint and low water usage. We will watch the testing developments later this year with great interest and wish them good luck. Many thanks for an interesting visit.

5th CCS Cost Network Workshop (13th-14th September 2017)

Monica - BlogThe 5th Cost Network Meeting took place in Imperial College London, chaired by John Gibbins, from UKCCSRC. With the presence of a varied scientific community, once again this workshop was full of valuable presentations.

The meeting was divided in two days, starting with a review on the UK studies and large CCS projects. From those sessions, it was interesting to see the techno-economic assessment of emerging technologies, presented by Amec Foster Wheleer. During their presentation, we saw promising results based on a decrease of the energy penalty on new systems compared to traditional CCS. The large projects were represented by Petranova and Quest plants. The day continued with the session focused on the cost of emerging processes, where NET Power and the Membrane-based technology were presented, and concluded with CCS in Energy-Economic models, presented by University College Cork and Oxford University.

The second day started with the intervention of Clara Heuberger, from Imperial College London, who presented the role of CCS within the UK electricity system. Following this presentation, Andy Boston, from Red Vector, showed the results on the Australian case. As main conclusions from both speakers, we saw that flexibility is essential to assess the integration of CCS technologies within a techno-economic framework. As example, in Australia, different conditions based on locations are identified, so the integration of decarbonising technologies must be adapted accordingly. Likewise, as we saw in past events, CCS should be part of a synergy of technologies, which would include renewable energy amongst other strategies. Inflexible grids would struggle in the future and reliable low emissions electricity comes at a cost. In this scenario, deeper decarbonisation levels can be achieved using CCS.

The last section of the cost network meeting was compound by three parallel workshop sessions, where the attendees were divided in three groups based on their interests. I was lucky to be part of the session “Learnings from demonstration projects: what will be the next plant cost? ”, chaired by Jeff Hoffmann, from USDOE NETL. In this session, interesting questions on the current CCS demonstration scenario were discussed: Firstly, the discussion started with the debate on the CCS status, currently based on FOAK (first of a kind) plants or large-demonstration projects. Additionally, while we see over-estimation of costs in those running plants to increase the trustworthiness on the carbon capture system, stakeholders consider that the cost will be reduced by 20-30% on the next constructions through a more precise design. Moreover, not only costs, but lessons from those projects are both technical and economically beneficial. In consequence, the strategy for the next generation of plants can take two pathways: First, going ahead to construct the SOAK (second of a kind) plant; or second, improve the systems at lab/plant scale and wait longer to scale it up. Nevertheless, IP issues will play an important role in CCS costs. While learnings can be extracted from projects running, still that could impact on the next plants costs.

The two days of the cost network workshop were charged of open discussions on methodologies to assess CCS costs and attendees showed high interest in continuing with those sessions. We look forward to attend the next one.
