This paper explores a possible waste-based economy transition strategy. Digestate from the organic fraction of municipal solid waste (OFMSW) is considered, as well as a low-added value product to be properly valorized. In this regard, air gasification may be used to produce syngas. In this work, the production of methanol, hydrogen, or electricity from digestate-derived syngas was assessed by ChemCAD process simulation software. The process scheme of methanol production comprises the following parts: water gas shift (WGS) with carbon capture and storage units (CCS), methanol synthesis, and methanol purification. In the case of hydrogen production, after WGS-CCS, hydrogen was purified from residual nitrogen by pressure swing absorption (PSA). Finally, for electricity production, the digestate-derived syngas was used as fuel in an internal combustion engine. The main objective of this work is to compare the proposed scenarios in terms of CO2 emission intensity and the effect of CO2 storage. In particular, CCS units were used for methanol or hydrogen production with the aim of obtaining high equilibrium yield toward these products. On the basis of 100 kt/year of digestate, results show that the global CO2 savings were 80, 71, and 69 ktCO2eq/year for electricity, methanol, and hydrogen production, respectively. If carbon storage was considered, savings of about 105 and 99 ktCO2eq/year were achieved with methanol and hydrogen production, respectively. The proposed scenarios may provide an attractive option for transitioning into methanol or hydrogen economy of the future.

Carbon capture and storage (CCS) is increasingly considered to be a tool that can significantly reduce the emission of CO2. It is viewed as a technology that can contribute to a substantial, global reduction of emitted CO2 within the timeframe that seems available for mitigating the effects of present and continued emission. In order to develop the CCS method the European Union (EU) has supported research programmes for more than a decade, which focus on capture techniques, transport and geological storage. The results of the numerous research projects on geological storage are summarised in a comprehensive best practice manual outlining guidelines for storage in saline aquifers (Chadwick et al. 2008). A detailed directive for geological storage is under implementation (European Commission 2009), and the EU has furthermore established a programme for supporting the development of more than ten large-scale demonstration plants throughout Europe. Geological investigations show that suitable storage sites are present in most European countries. In Denmark initial investigations conducted by the Geological Survey of Denmark and Greenland and private companies indicate that there is significant storage potential at several locations in the subsurface.

Reservoir Conditions

Worldwide experiences related to geological CO2 storage show that the process of the injection of carbon dioxide into depleted oil reservoirs (CCS-EOR, Carbon Capture and Storage—Enhanced Oil Recovery) is highly profitable. The injection of CO2 will allow an increasing recovery factor (thus increasing CCS process profitability) and revitalize mature reservoirs, which may lead to oil spills due to pressure buildups. In Poland, such a solution has not yet been implemented in the industry. This work provides additional data for analysis of the possibility of the CCS-EOR method’s implementation for three potential clusters of Polish oil reservoirs located at a short distance one from another. The aim of the work was to examine the properties of reservoir fluids for these selected oil reservoirs in order to assure a better understanding of the physicochemical phenomena that accompany the gas injection process. The chemical composition of oils was determined by gas chromatography. All tested oils represent a medium black oil type with the density ranging from 795 to 843 g/L and the viscosity at 313 K, varying from 1.95 to 5.04 mm/s. The content of heavier components C25+ is up to 17 wt. %. CO2–oil MMP (Minimum Miscibility Pressure) was calculated in a CHEMCAD simulator using the Soave–Redlich–Kwong equation of state (SRK EoS). The oil composition was defined as a mixture of n-alkanes. Relatively low MMP values (ca. 8.3 MPa for all tested oils at 313 K) indicate a high potential of the EOR method, and make this geological CO2 storage form more attractive to the industry. For reservoir brines, the content of the main ions was experimentally measured and CO2 solubility under reservoir conditions was calculated. The reservoir brines showed a significant variation in properties with total dissolved solids contents varying from 17.5 to 378 g/L. CO2 solubility in brines depends on reservoir conditions and brine chemistry. The highest calculated CO2 solubility is 1.79 mol/kg, which suggest possible CO2 storage in aquifers.

AbstractThe Endurance, four-way, dip-closed structure in UK Blocks 42/25 and 43/21 occurs over a salt swell diapir and within Triassic and younger strata. The Lower Triassic Bunter Sandstone Formation reservoir within the structure was tested twice for natural gas (in 1970 and 1990) but both wells were dry. The reservoir is both thick and high quality and, as such, an excellent candidate site for subsurface CO2 storage.In 2013 a consortium led by National Grid Carbon drilled an appraisal well on the structure and undertook an injection test ahead of a planned development of Endurance as the first bespoke storage site on the UK Continental Shelf with an expected injection rate of 2.68 × 106 t of dense phase CO2 each year for 20 years. The site was not developed following the UK Government's removal of financial support for carbon capture and storage (CCS) demonstration projects, but it is hoped with the recent March 2020 Budget that government support for CCS may now be back on track.

The CO2CRC storage research site, in the Otway Basin (south-west Victoria), focuses on understanding fundamental mechanisms of geological carbon storage resources in saline aquifers. The world-leading project is demonstrating that carbon capture and storage is a technically and environmentally safe way to make deep cuts into global greenhouse gas emissions. Upstream Production Solutions (Upstream PS) are the nominated site manager and have provided ongoing project management, facilities engineering, construction, operations and maintenance services to CO2CRC from the project’s inception. Over the course of the last 10 years, the project has undergone well and facilities design, and drilling and construction phases, with separate injections of over 80000 tonnes of CO2 rich gas into the formation for research purposes. Unique and dynamic concurrent projects as at the time of writing are: designing a fifth well for the project; commissioning a carbon capture package to provide valuable research data on emerging membrane and adsorption technologies; maintaining and monitoring the overall non-operational site; and planning for a well abandonment. This sphere of project activity across the whole life cycle requires a robust and holistic focus on management of risk, planning, implementation of right sized solutions and strong stakeholder communications. This paper details the nature of projects executed and specific challenges encountered and met whilst still following lean practices for a safe yet cost-effective operation for this world leading CO2 research project.

An aim of the paper is to show recent data obtained from a new experimental set-up build for the production of the CO2 gas hydrates. The purpose of the experimental set-up is to analyse the practical aspects of the transformation gaseous CO2 to the hydrates. The deserving effort to decrease impacts of the global warming is containing the more questionable attempt to capture the CO2 produced within the electricity production and to avoid a releasing to the atmosphere. The storage in the form of the gas hydrates present an alternative way to more known technologies involved in the projects of CCS (Carbon Capture and Storage). The production of the gas hydrate is observed in the set-up with simultaneously acquired data of state condition close to the phase boundary. The presented work has two goals, first is the estimation of the transformation efficiency of the CO2 to the hydrates in compare with the theory and second goal is obtaining of the data for new CO2 hydrates production set-up with liquid circulation and possibility to separate pure hydrate. The experimental analysis of the gas hydrates production process can help to estimate the practical aspects of the hydrates production for a possibility of CO2 storage in this form.

The integrity of natural systems is already at risk because of climate change caused by the intense emissions of greenhouse gases in the atmosphere. The goal of geological carbon sequestration is to capture, transport and store CO2 in appropriate geological formations. In this review, we address the geological environments conducive to the application of CCS projects (Carbon Capture and Storage), the phases that make up these projects, and their associated investment and operating costs. Furthermore it is presented the calculations of the estimated financial profitability of different types of projects in Brazil. Using mathematical models, it can be concluded that the Roncador field presents higher gross revenue when the amount of extra oil that can be retrieved is 9.3% (US$ 48.55 billions approximately in 2018). Additional calculations show that the Paraná saline aquifer has the highest gross revenue (US$ 6.90 trillions in 2018) when compared to the Solimões (US$ 3.76 trillions approximately in 2018) and Santos saline aquifers (US$ 2.21 trillions approximately in 2018) if a CCS project were to be employed. Therefore, the proposed Carbon Capture and Storage method in this study is an important scientific contribution for reliable large-scale CO2 storage in Brazil.

The CO2CRC Otway Project continues to demonstrate that carbon capture and storage is a viable option for CO2 mitigation. The CO2CRC Otway Project is Australia’s first CO2 demonstration project, with two projects completed, involving geological storage of some 80000 tonnes of CO2 over the past 10 years. The project was initially authorised for a single stage with a finite life, but the growing requirements of the global carbon capture and storage community required further research on carbon capture and storage technologies and behaviour (via Stages 2 and 3), and so the project was extended. CO2CRC has undertaken 360-degree stakeholder engagement processes throughout the project, regularly consulting with regulators, governments, industry, partners, researchers and the community. This has been especially important as the project changed, operating in a niche space between Victorian environment, petroleum and water Acts. This process has allowed CO2CRC to contribute to alignment efforts within regulatory bodies, to enhance regulations to cover project activities, ensuring best practices are documented and observed to the satisfaction of the regulators and wider community. The Otway Basin in south-west Victoria is a region not immune to broader community concerns regarding the oil and gas and other industries. The surrounding area is predominately dairy farming, with locals relying heavily on the aquifers beneath their land. Although such a backdrop suggests potentially high levels of concern and scrutiny, especially when projects necessitate drilling or other invasive activities, the project has maintained strong local stakeholder engagement and support due to ongoing implementation and evaluation of the stakeholder management processes.
