Book Reference Policy Support System for Carbon Capture and Storage and Collaboration between Belgium-the Netherlands “PSS-CCS”, Final report
Context The climate on Earth is changing due to the increased emissions of CO2 into the atmosphere, and these changes are expected to have a predominantly negative impact, with potentially dramatic economic, social and environmental consequences. The increased concentrations of CO2 are already resulting in acidification of the oceans, which adds further to the environmental pressure. Reducing the emissions of CO2 is therefore of prime importance. CO2 Capture and Storage (CCS) is considered as an essential element in the portfolio of measures, and has the potential to reduce the CO2 emissions from large industrial facilities to nearly zero. This has been recognised by the international community and especially Europe is being proactive in stimulating the development and implementation of CCS. Policy related research on CCS in Belgium has been centralised in the PSS-CCS projects (Policy Support System for Carbon Capture and Storage). Phase one (PSS-CCS I) started at the end of 2005 and the results were integrally published in 2009 (Piessens et al., 2009). This work was continued in the projects PSS-CCS II, the actual phase two, and the international valorisation project PSS-CCS BeNe which extended the scope to the Netherlands and created official bridges between the national CCS projects in Belgium and the Netherlands (CATO-2). Objectives From the start, the PSS-CCS projects (Policy Support System for Carbon Capture and Storage) have promised to provide detailed and objective insights in the role that CCS can play in the CO2 mitigation efforts of Belgium. Achieving this central objective is only possible by bringing together information, data and methodologies from widely different fields. The list below gives a brief overview of these activities, which have often resulted in deliverables which are usually to be regarded as important achievements in their own right. - Inventory of the industrial emission sources for CO2 in Belgium at plant and sector level, for providing an actual view on these emissions and the need to replace aging infrastructure. - Economic and technical analysis of the different technologies and their performance that allow capturing CO2 from power plants and other industrial facilities. - Development and calibration of a least-cost routing application for transport of CO2 by pipeline. - Summary of the geological data to identify geological reservoirs (aquifers and coal related storage options) that are potentially suited for geological storage of CO2. - Risk evaluation of different types of reservoirs and a techno-economic overview of the different techniques to monitor a CO2 reservoir. - Overview of the storage options in neighbouring countries accessible from Belgium, and an assessment on the domestic use of these reservoirs in those countries. - Analysis of the production, conversion and consumption of energy in Belgium using the TIMES-BE model, including CCS technologies. - Development of the PSS II simulator for detailed and ad-hoc predictions of CCS implementation in Belgium. - Evaluating the simulation results of the two models regarding the economic and environmental role that CCS can play under different scenarios. Conclusions The PSS-CCS projects have looked into the different, but related aspects of CCS. Capture of CO2 in the power sector is retaken and update in this report, but particular attention is given to how capture technologies can be integrated in industrial production processes. Particular attention is given to the production of cement, iron and steel, hydrogen, ammonia, refineries and industrial boilers, making this report a reference document for the capture from industrial sources. Cost estimates of those technologies are provided where possible, often indicating that capture can be more cost efficiently than in the power sector (e.g. steel, hydrogen...). For others, such as refineries, it may be quite challenging because of the complexity of such installations. The storage of CO2 is only of secondary importance when considering only costs, but is essential in the project planning and communication. This is why, now demonstration projects in neighbouring countries have become a reality, this topic is attracting an increasing amount of attention. This report in particularly looks at storage in coal bearing sequences by evaluating the different potential migration routes of CO2. In an attempt to quantify the amounts of CO2 that may migrate to the surface, a comparison is made with published estimates. Conservative estimates for leakage along abandoned wells would be below the health concentration of CO2, and vertical migration of CO2 in the Campine Basin in absence of such wells or conductive faults would be below meter scale at a 100y time resolution. Migration of CO2 out of the coal-bearing strata would be even more difficult, since coal acts as both a reservoir and seal, and additional sealing layers are present within the heterogeneous sequence. Nevertheless, as also required by European law, extensive monitoring is required. A portfolio of different technologies is required to achieve a the resolution required for confirming that CO2 is not leaking from the reservoir, leading to relatively high monitoring costs for small reservoirs or reservoirs with low injectivity. A comprehensive overview of the coal sequences in the Hainaut Basin indicates a storage potential of 500 to 700 Mt in this area. Injection strategies for coal are discussed acknowledging the geological particularities of this coal basin. The capacity of the Dinantian aquifer in this area is comparable to that of coal, but of particularly interest because of the high injectivity. The databases of the PSS simulator have been updated and extended according to the newly acquired data in this project, and have been calibrated for pipeline routing against confidential data from industry. Together with the important improvements, the current version (PSS II) produces realistic and reliable forecasts on power technologies based on coal, natural gas and biomass, as well as for the steel sector. PSS II is used in parallel with TIMES-BE, using large the same databases to make the results compatible. These models show that CCS will be a likely economic option in the power sector, but especially in industry. However, relatively high ETS prices for CO2 emissions are required to trigger large scale implementation of CCS in especially the power sector. An essential factor in assuring that very low emission targets are realised by 2050, a portfolio of technologies is required: if technologies are left out, the probability that the low targets are reached decreases dramatically. Technology lock-in additionally poses a real threat, but can be mitigated with appropriate policy measures. When it comes to storage, the development of domestic storage capacity is justified, although Belgium will additionally have to rely on the export of CO2. Contribution of the project in a context of scientific support to a sustainable development policy During the more or less five years during which the PSS-CCS projects have been active, they have been able to fill the need for information and follow-up on the topic of CCS in Belgium. This resulted in a large and active follow-up committee representing over 30 institutes, including many administrations and stakeholders that weigh on environmental and economic policy. The different valorisation events of the project were initially strongly focussed on the dissemination of correct and objective information on CCS, for which the international interest was strongly growing. This was in line with the activities within the project of which the earliest tasks were focussed on gathering and organising the data required for modelling the role of CCS. Energy models in Belgium were at that time also looking to include data on CCS technologies as a future option, leading to a direct feed of information into e.g. the Belgian TIMES- BE model. Also the reports of the Federal Planning Bureau (PRIMES model) cite PSS-CCS as a main reference. An important surge for information was during the preparation of the European CCS directive (Directive 2009/31/EC). Technical information regarded mainly the storage of CO2, the prime focus of the directive, but also the outlooks produced by the project were used to consider the scale and relevance of CCS for Belgium. Also other organisations and networks called upon the PSS-CCS partners for direct advice, or for presentations on the topic. The reader is referred to chapter 4 (DISSEMINATION AND VALORISATION) for an overview of the main and official valorisation activities originating from the PSS-CCS projects. Within Belgium and its regions, CCS is a well-known and documented option in mid- and long-term energy projections thanks to the catalytic role of the PSS-CCS projects. The now fully mature PSS II simulator and its databases currently play an important role in exchange activities with other countries through European collaboration and network projects (e.g. Welkenhuysen & Piessens, 2011b). This export of expertise may result in an impact in those countries, comparable to that of the PSS-CCS projects in Belgium.

Manual Reference Potential impact of wash water effluents from scrubbers on water acidification in the southern North Sea
Sulphur Oxides (SOx) in atmospheric ship emissions resulting from the burning of fuel with high sulphur content are known to be harmful to human and ecosystem health. Since January 1st 2020, the International Maritime Organisation (IMO) lowered the previous limit for sulphur content in ship fuel from 3.5% m/m (mass by mass) to 0.50%. In the emission control areas (SECAs), the limit for the sulphur content had been set to 1.0% in 2010 and is kept below 0.1% since 2015. To comply with these limits, ship operators and owners can switch to fuel oil with lower sulphur content (LSFO). Alternatively, they can continue to burn fuel with high sulphur content by using technical means such as exhaust gas cleaning systems (or scrubbers) that reduce the atmospheric SOx emissions to a level equivalent to the required fuel oil sulphur limit. Scrubbers use sea water as cleaning media to remove SOx from the air emissions. There are three main categories of scrubbers: (1) the open-loop scrubbers that continuously discharge their wash water effluent, (2) the closed-loop scrubbers that treat the wash water before it is discharged, and (3) the hybrid scrubbers that can switch from open to closed modes. Scrubbers transform the air pollution into direct marine discharge. As hybrid scrubbers are more likely to discharge their sulphur waste into sea water rather than using land infrastructures, they are hereafter taken as open-loop ones. The effect of SOx contribution from ship on sea water pH is assessed for the English Channel and the southern North Sea by means of a marine biogeochemical model that includes a detailed description of the carbonate chemistry. This model allows testing different scenarios of SOx contribution resulting from the maritime traffic. To this end, realistic scenarios with ship traffic density estimated for the years 2019, 2020 and 2030, assuming a year-to-year ship traffic increase of 3.5% and several SOx pollution reduction strategies have been tested. An additional model simulation with null SOx contribution from the shipping sector is used as a reference level to comparatively assess the impact of each scenario on the sea water pH. Model results show a pH decrease of 0.004 units over the whole domain in case of a 2019-like ship traffic density with 15% of the fleet (in Gross Tonnage) using open-loop and hybrid scrubber systems. For future scenarios, assuming that 35% of the fleet is equipped with open-loop and hybrid scrubbers, the pH is estimated to decrease by 0.008 to 0.010 units in average over the whole domain. The magnitude of pH changes is not evenly distributed through space. According to the model results, the largest pH changes would occur in areas of high traffic density, such as along the Belgian and Dutch coasts and in the vicinity of large harbours such as Rotterdam. Ocean acidification rate attributed to climate change is estimated at 0.0017-0.0027 pH units per year. In comparison, the total pH decrease owing to the use of open-loop scrubbers would be equivalent to 2 to 4 years of climate change acidification on average over the whole domain, and to 10 to 50 years, in more local areas. The cumulative impact of ocean acidification due to climate change and to maritime traffic should therefore be considered in ecosystem assessment studies.
