“…One solution could be the integration of carbon capture [9,10] e.g. including oxy-combustion [11,12], pre-combustion [13,14,15,16] and post-combustion [17,12,18] into natural gas power stations. Kvamsdal et al [10] showed the existence of several promising configurations in which a gas turbine cycle (400MWe) was coupled with a carbon capture process.…”

There is a reliance on negative emissions technologies (NETs), primarily in the form of Bioenergy with Carbon Capture and Storage (BECCS) in most Integrated Assessment Model (IAM) scenarios which are capable of limiting the maximum global temperature rise to 1.5-2 • C. Two currently independent features of transition pathways are fuel switching from coal to gas, and the deployment of BECCS. The former makes natural gas an important transition fuel which at the same time could be combined with biomass to further abate emissions. To date the majority of studies have considered BECCS in the context of a conversion from coal-fired base configuration. There is therefore a pressing need to identify routes for the effective utilisation of biomassderived fuels in the context of gas-fired power generation infrastructure. In this contribution, we study three distinct CCS-based processes which combine natural gas and biomass capable of producing low-, or carbon-negative power. Both fuel supply chains are considered in order to quantify the net CO 2 emissions. An important insight is the configuration-specific impact of biomass co-combustion on the overall carbon intensity of power generated. We found that an external biomass combustion configuration was the most carbon negative, removing between 0.5-1 ton of CO 2 per MWh of power generated. Results revealed a trade-off between carbon negativity and efficiency of the processes. The generation of net carbon negative power is observed to be highly sensitive to the carbon footprint of the biomass supply chain.

“…Traditionally, power plants are based on coal-fired power/steam generation. All conventional sources of steam generation such as gas turbine combined cycle (CC) [10,11], integrated gasification combined cycle (IGCC) [12][13][14], and pressurized fluidized bed combustion (PFBC) [15,16] are fuel based steam generation processes [8]. Environmentally speaking, decreasing the carbon footprint in chemical plants requires the intensive attempts to optimize the energy requirements by reduction of the consumption of the energy and lessen the carbon emissions associated with the remaining energy.…”
