The CO2CRC has a demonstration storage project underway in the Otway Basin of southwest Victoria. The aim of the project is to demonstrate that carbon capture and storage (CCS) can be performed under Australian conditions. The project involves extracting CO2 rich gas from an existing field and injecting it into a nearby depleted natural gas field for long-term storage. Injection commenced in April 2008, and approximately 100,000 tonnes of CO2 are planned to be injected through a new injection well drilled in 2007. A multi-disciplinary monitoring and verification (M&V) program has been in place from late 2005 and a baseline state of the subsurface, near surface and atmospheric conditions has been comprehensively defined prior to the commencement of injection. The project has also been instrumental in unravelling the legislative overlaps between jurisdictions and has helped shape the regulatory regime being developed by the Victorian Government. At the present time over 35,000 tonnes of CO2 has been injected and a variety of monitoring data collected. This paper aims to provide an update on the holistic project and how some of the findings may lead to expediting commercial uptake of CCS in Australia.

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.

Geological and ocean sequestration of carbon dioxide is a potential climate change mitigation option that is currently receiving an increasing level of attention within business, academic and policy communities. This paper presents a preliminary investigation of possible public reaction to the technologies under consideration. Using a focus group approach, we consider the similarities between carbon storage technologies and analogous technologies that have generated strong reactions with the public. Initial results suggest that, in principle, carbon capture and storage may be seen as an acceptable approach as a bridging policy while other options are developed. However, concerns were raised regarding the safety of storage and trust in the ability of the various institutions to oversee the process in the long term. This analysis forms part of an on-going study which will continue to investigate the perceptions of a range of stakeholders.

Bioenergy with carbon capture and storage (BECCS) is one strategy to remove CO2 from the atmosphere. To assess the potential scale and cost of CO2 sequestration from BECCS in the US, this analysis models carbon sequestration net of supply chain emissions and costs of biomass production, delivery, power generation, and CO2 capture and sequestration in saline formations. The analysis includes two biomass supply scenarios (near-term and long-term), two biomass logistics scenarios (conventional and pelletized), and two generation technologies (pulverized combustion and integrated gasification combined cycle). Results show marginal cost per tonne CO2 (accounting for costs of electricity and CO2 emissions of reference power generation scenarios) as a function of CO2 sequestered (simulating capture of up to 90% of total CO2 sequestration potential) and associated spatial distribution of resources and generation locations for the array of scenario options. Under a near-term scenario using up to 206 million tonnes per year of biomass, up to 181 million tonnes CO2 can be sequestered annually at scenario-average costs ranging from $62 to $137 per tonne CO2; under a long-term scenario using up to 740 million tonnes per year of biomass, up to 737 million tonnes CO2 can be sequestered annually at scenario-average costs ranging from $42 to $92 per tonne CO2. These estimates of CO2 sequestration potential may be reduced if future competing demand reduces resource availability or may be increased if displaced emissions from conventional power sources are included. Results suggest there are large-scale opportunities to implement BECCS at moderate cost in the US, particularly in the Midwest, Plains States, and Texas.

This paper focuses on relevant legal and policy arrangements necessary for the development of Carbon Capture and Storage (CCS) in China. Special attention is paid to laws and policies on the capture, transport and storage of CO2. In particular, the storage of CO2 is very challenging for the existing regulatory regime, considering the complexity and novelty of the issue. Specifically speaking, the following analysis is made from three perspectives: (1) regulatory regime; (2) fiscal and financial support and (3) environmental regulations (including access to information and public participation). Having summarized and analyzed relevant issues and international experience, this paper identified the foundation, barriers and gaps exist in China. Priority choices and targets for legal and policy development in different periods were also made according to the status quo of CCS development in China and the periods of development recommended by the Asian Development Bank.

Soil-gas concentrations and flux were measured during 20 separate measurement campaigns at the TOTAL Lacq-Rousse carbon capture and storage (CCS) pilot site, southern France, where 51,000 tons of CO2 were injected in a depleted natural gas field. Baseline data (September 2008 to December 2009) are compared to monitoring data from the injection (March 2010 to March 2013) and post-injection (February 2014 to December 2015) periods. CO2 soil-gas concentrations varied from atmospheric concentrations to more than 16% vol. with 1.4% as median value. Summer data showed high CO2 concentrations in the soil that remained quite high during winter. Median CO2 flux at the soil/atmosphere interface was close to 4.4 cm3·min−1·m−2. Carbon-isotope ratios measured on CO2 in soil gas had a mean value of −23.5 ± 3.1‰, some deviation being due to atmospheric CO2. Comparison between different gas species and the influence of temperature, pressure and soil-water content suggest that gases in near-surface environments are produced locally and naturally, and are unrelated to CO2 ascending from the storage reservoir. Monitoring of CO2 injection and the use of threshold levels is discussed as part of a practical approach considering specific regulations for the Lacq-Rousse CCS pilot experiment and constraints for the site operator.

AbstractThe concentration of CO2, one of the most important greenhouse gases (GHG), has reached to 409.8 ± 0.1 ppm in 2019. Although there are many carbon capture and storage (CCS) methods, they are very costly and their long term use raises concern about environmental safety. Alternatively, bio-sequestration of CO2 using microalgal cell factories has emerged as a promising way of recycling CO2 into biomass via photosynthesis. In the present study, Indigenous algal strain Pseudanabaena limnetica was cultivated in pneumatically agitated 60-L flat-panel photobioreactor system. The gas was released from Bio-CNG plant as by-product into Na2CO3-rich medium and cultivated in semicontinuous mode of operation. It was observed that when CO2 was sparged in seawater-based 0.02 M Na2CO3 solution, maximum CO2 was dissolved in the system and was used for algal cultivation. Control system produced 0.64 ± 0.035 g/L of biomass at the end of 15 days, whereas CO2 sparged Na2CO3 medium produced 0.81 ± 0.046 g/L of biomass. When CO2 from Bio-CNG station was fed, it resulted in biomass production of 1.62 ± 0.070 g/L at the end of 18 days compared to 1.46 ± 0.066 g/L of biomass produced in control system which was not fed with gas released from Bio-CNG plant as by-product. Thus, feeding CO2 directly into Na2CO3 medium and operating the system semicontinuously would be efficient for scrubbing CO2 from commercial Bio-CNG plant. This study proves that feeding CO2 gas from Bio-CNG plant into Na2CO3-rich alkaline system can be used to feed algae for enhanced biomass production.

The capture and long-term storage of carbon dioxide from power plants and other industrial installations may prove a key technology in climate change abatement strategies. Regulatory frameworks for carbon capture and storage (CCS) are now being developed in a number of jurisdictions. The European Union produced the first comprehensive legislation on the subject in 2009, which provides a compelling example of challenges associated with the design of regulation dealing with a novel technology. This chapter identifies three issues, each of which reflects aspects of regulatory legitimacy: the extent to which states within a federal or quasi-federal system should have the legal discretion to reject a technology; the way in which regulation provides for opportunities for public participation and engagement in issues concerning the new technology; and whether, and at what point, the state should assume responsibility for storage sites, given the long timescales necessary for secure storage.
