Rewarding of extra-avoided GHG emissions in thermochemical biorefineries incorporating Bio-CCS

“…The incorporation of Bio-CCS in thermochemical biorefineries has been modeled in the literature [3,33,[35][36][37][38][39][40][41][42][43]. In the design of thermochemical biorefineries, it is common to have a unit for the removal of CO 2 from the syngas (equivalent to pre-combustion CO 2 capture in IGCC power plants) in order to meet the requirement of the synthesis section [42].…”

“…Therefore, the GHG balance is not considered, even if it involves GHG savings above the minimum target. Based on these proposals, some authors have economically assessed the rewarding of Bio-CCS incorporation into different configurations of thermochemical biorefineries producing energy carriers [3,33,[35][36][37][38][39][40][41][42][43]. In all cases, the rewarding was via the sale of CO 2 allowances.…”

“…To the best of our knowledge, there is no previous studies of this kind in the literature. Unlike previous studies [3,33,[35][36][37][38][39][40][41][42][43][45][46][47][48][49][50], in this study a general analysis is presented, where the main factors affecting the update of the techno-economic assessment are described. Since thermochemical biorefineries achieve a GHG saving above the minimum target in the EU, the sale of all extra-avoided GHG emissions (not only from Bio-CCS) is analyzed.…”

Storage capacity assessment of liquid fuels production by solar gasification in a packed bed reactor using a dynamic process model

“…2). Typically the FT option is likely to be more desirable due to the higher value of liquid fuels over electricity [13,31]. However, a prerequisite to FT liquids production with currently available FT reactors is the need to propose a method with which to achieve a steady-state output in both the flow-rate and composition of the upgraded syngas over a full solar year despite variable output from the packed bed gasifier.…”

Syngas-based annex concepts for chemical energy storage and improving flexibility of pulverized coal combustion power plants

“…The investment and operational costs of stand-alone coal gasification concepts are high compared to oil-based chemicals because of solids handling, gas purification and treatment of effluent streams [14]. The increasing interest in coal-based polygeneration power plants is aiming at product flexibility and resource utilization for higher total efficiencies and improved economics of the overall plant [15][16][17][18]. The paper of Li et al [15] addresses coal-based co-generation of SNG and electricity.…”
