“…Finally, once captured CO 2 , must be purified to avoid two-phase flow problems and compressed as a supercritical fluid transported by pipeline to the storage site. Indicatively, a CO 2 flow of about 1.5Mt per year, produced from a baseload 530MW natural gas combined cycle (NGCC) plant, requires compression power of about 23MW or 4.3% of its output 29 . For distances greater than 100km, this becomes insufficient and repressurization stations would be needed along the way.…”

Carbon capture and storage (CCS) for fossil fuel power plants is perceived as a critical technology for climate mitigation. Nevertheless, limited installed capacity to date raises concerns about CCS ability to scale sufficiently. Conversely, scalable renewable electricity installations-solar and wind-are already deployed at scale and have demonstrated a rapid expansion potential. Here we show that power sector CO 2 emission reductions accomplished by investing in renewable technologies generally provide a better energetic return than CCS. We estimate the electrical Energy-Return-on-Energy-Invested ratio of CCS projects accounting for their operational and infrastructural energy penalties to range between 6.6:1 and 21.3:1 for 90% capture ratio and 85% capacity factor. These values compare unfavorably to dispatchable scalable renewable electricity with storage, which ranges from 9:1 to 30+:1 under realistic configurations. Therefore, renewables plus storage provide a more energetically effective approach to climate mitigation than constructing CCS fossil power stations.

Lignocellulosic Ethanol in a Greenhouse Gas Emission Reduction Obligation System—A Case Study of Swedish Sawdust Based-Ethanol Production

2020

A greenhouse gas (GHG) emission reduction obligation system has been implemented in the Swedish road transport sector to promote the use of biofuels. For transportation fuel suppliers to fulfil this obligation, the volume of biofuel required decreases with decreasing life cycle GHG emission for the biofuel, linking lower GHG emission to higher economic value. The aim of this study was to investigate how the economic competitiveness of a Swedish emerging lignocellulosic-based ethanol production system would be influenced by the reduction obligation. The life cycle GHG emission for sawdust-based ethanol was calculated by applying the method advocated in the EU Renewable Energy Directive (RED II). The saving in GHG emissions, compared with fossil liquid transportation fuels, was 93% for a potential commercial production system in southern Sweden. This, in turn, will increase the competitiveness of sawdust-based ethanol compared to the mainly crop-based ethanol currently used in the Swedish biofuel system, which has an average GHG emission saving of 68%, and will allow for an almost 40% higher price of sawdust-based ethanol, compared to the current price of ethanol at point of import. In a future developed, large-scale market of advanced ethanol, today’s GHG emission reduction obligation system in Sweden seems to afford sufficient economic advantage to make lignocellulosic ethanol economically viable. However, in a short-term perspective, emerging lignocellulosic-based ethanol production systems are burdened with economic risks and therefore need additional economic incentives to make a market introduction possible.

“…Only one pilot project is located in South Africa and is operational while another 'in planning' is still situated in South Africa. In addition, IEA estimated that an effort to reduce halve the global CO2 emission by half without CCS would increase the cost to more than 70% per year [14] El-Suleiman et al [15] presented the power requirements of compression of CO2 using Peng-Robinson's equation of state without actually computing the energy cost. Lazic et al [16] did an extensive study of the cost of installation of a CCS system in the Humber region of the UK.…”

Carbon capture and storage (CCS) has been recognized as one major technology that could sustain a greener environment. Because of the constant use of fuel for power generation, which releases CO2 that could be sequestered in geologic sites preventing their eventual release to the atmosphere. This study used Afam IV Gas Turbines in Nigeria as a case study and evaluated the emission of CO2 from the plants and the technoeconomic analysis of transporting captured CO2 from this power plant to Jones Creek (the proposed sequestration site in this study). The CO2 emission factor was determined from the daily energy generation from the gas consumption of the two turbines at the plant. Pipe Flo Professional 14 software was used for the pipeline design that was used for the transportation. The CO2 emissions from the two turbines were found to have a flow rate of 0.68kg/s, requiring 4,416kW and 61.402kW of compressor power and pump power, respectively, each at 85% efficiency. This power requirement constitutes 3.44% of 130MW of the installed capacity of the two turbines at Afam IV. The capacity of Jones Creek was found to be 8.94x10 6 m 3 , and the pipeline cost for the transportation of CO2 was found to be ₦21.994Billion. The National Electricity Regulatory Commission (NERC) Multi-Year Tariff Order (MYTO) D3 billing rose to 600% during the construction period but dropped to 19% increment beyond the construction period as a result of the CO2 compression and transportation. It is recommended that the Federal Government of Nigeria should start to implement policies that would propel oil and gas companies in Nigeria to start considering CCS as an emission mitigation option in Nigeria.
