“…The options for carbon capture vary from solvent-based technologies such as Absorption/desorption using Monoethanolamine (MEA) [46,47], to underdeveloped methods such as oxyfuel combustion [48], membrane separation [49,50], nanomaterial sorbents [51] and chemical looping [52,53]. In parallel, intensive research is devoted to CO 2 utilization for producing fuel and products [54], and among them microalgae cultivation has gained significant research interest [55,56].…”

Biomass-derived fuels can contribute to energy sustainability through diversifying energy supply and mitigating carbon emissions. However, the biomass chemistry p`oses an important challenge, i.e., the effective hydrogen to carbon ratio is significantly lower for biomass compared to petroleum, and biomass conversion technologies produce a large amount of carbon dioxide by-product. Therefore, CO2 capture and utilization will be an indispensable element of future biorefineries. The present research explores the economic feasibility and environmental performance of utilizing CO2 from biomass pyrolysis for biodiesel production via microalgae. The results suggest that it is possible to increase biomass to fuel conversion from 55% to 73%. In addition, if subsidies and fuel taxes are included in the economic analysis, the extra produced fuel can compensate the cost of CO2 utilization, and is competitive with petroleum-derived fuels. Finally, the proposed integrated refinery shows promise as CO2 in the flue gas is reduced from 45% of total input carbon to 6% with another 19% in biomass residue waste streams.

“…It is possible that the analogous Australian tax of US$24 (Syed and Penney 2011) may similarly encourage further consideration of CCS. However, in the United States, where about 65 Mt CO 2 is used annually in enhanced oil recovery, it is estimated that current amine-based CCS technologies are likely to increase electricity costs by up to 30 % (Bhown and Freeman 2011).…”

Climate change is occurring largely as a result of increasing CO 2 emissions whose reduction requires greater efficiency in energy production and use and diversification of energy sources away from fossil fuels. These issues were central to the United Nation climate change discussions in Durban in December 2011 where it was agreed that a legally binding agreement to decrease greenhouse gas emissions should be reached by 2015. In the interim, nations were left with the agreement reached at the analogous 2009 Copenhagen and 2010 Cancun meetings that atmospheric CO 2 levels should be constrained to limit the global temperature rise to 2°C. However, the route to this objective was largely left to individual nations to decide. It is within this context that options for reduction in the 95 % fossil fuel dependency and high CO 2 emissivity of the Australian energy profile using current technologies are considered. It is shown that electricity generation in particular presents significant options for changing to a less fossil fuel dependent and CO 2 emissive energy profile.

“…[3][4][5][6] Numerous materials have been developed for removal of CO2 from flue gas streams, including zeolites, 7 metal-organic frameworks (MOFs), 8 covalent organic frameworks, 9 and many others. 6 Particular attention has been paid to MOFs with coordinatively-unsaturated metal centers such as MOF-74, because they can exhibit a large CO2 uptake and a high selectivity due to the strong interaction between metal and CO2.…”
