“…Until now, most of research has been directed towards the development of oxy-fuel systems in pulverised coal (PC) boilers. In 2008, Vattenfall and Alstom successfully completed the commissioning the world´s first full chain 30 MW th Oxy-Fuel PC Pilot Plant Facility with CO 2 capture located in Schwarze Pumpe, Germany [4], and currently, a 500 MW th Oxy-Fuel PC Demonstration Plant is in progress in Jänschwalde, Germany. The Fundación Ciuden [5] in Spain is developing two plants able to operate from conventional to oxy-fuel combustion mode.…”

“…As seen on figure 1, Vattenfall built a large scale 30 MWth oxy-fuel pilot plant in Schwarze Pumpe in 2008 with coal feedstock (Strömberg, et al 2009). This pilot plant shows the possibility of the oxy-fuel implementation in thermal power plant.…”

The purpose of this work is to investigate the feasibility of an integrated system consisting of biomass-based power generation built-in with carbon capture technology combined with a water electrolysis unit operated by solar cells and wind turbines to produce fuel through the methanol synthesis process. The configurations are examined both technically and economically to determine their feasibility, and subjected to sensitivity analysis to determine their economic viability and optimum performance. Each integrated system has the same subsystems configuration including electrical power generation, electrolysis unit and solar/wind renewable electricity input.Three main system configuration variations for carbon extraction from biomass feedstock have been evaluated, based on pre-CCS in the form of integrated biomass gasification combined cycle (IGCC), in-situ CCS represented by Oxy-fuel combustion concept, and post-CCS via exhaust gas treatment, assuming the same access to woodchip feedstock.Two important substances for methanol production are carbon dioxide coming from biomass and hydrogen supplied by water electrolysis based on intermittent renewable energy sources. Coil evaporation system to provide CO2 separation would perform differently in each system; oxy-fuel, pre-CCS and post-CCS alternatives. Meanwhile, H2 supply is provided by the electrolysis process using water supply and electricity produced from solar and wind power. In addition, the effect of location and uncertainty factors is discussed among the sensitivity studies.The technical analysis shows that with 5 ton/hour of biomass feed, each system configuration could produce up to 5.8 t/h of methanol. On the other hand, the economic analysis shows LCOE of Oxy-fuel and the IGCC approaches the lowest possible to 0.086 €/kWh and 0.1060 respectively; while for the gasification process 689 €/ton methanol is produced. The interest rate risk can deviate from the energy cost up to 16% higher when the interest rate is increased from 8% to 9%.-i- Contents SAMMANFATTNINGSyftet med detta arbete är att undersöka genomförbarheten av ett integrerat system bestående av den biomassbaserade kraftproduktionen inbyggd med kolfångteknik och vattenelektrolyssystemet drivs av solceller och vindkraftverk för att producera bränsle genom metanolsyntesprocess.

“…Within the latter category, oxy-fuel combustion technologies utilise nearly pure oxygen instead of air for combustion, resulting in a flue gas that is mainly CO 2 and H 2 O and thereby facilitating the capture of CO 2 [22,63]. Nowadays, these technologies are in use in the aluminium, iron and steel and glass melting industries, whereas applications for new build pulverized coal fired power plant have not reached commercial scale yet but are at the prototype level [64]. Oxygen is usually produced by low temperature (cryogenic) air separation and novel techniques to supply oxygen to the fuel, such as membranes and chemical looping cycles are being developed.…”

The large-scale deployment of renewable energy sources (RES) is an important aspect of decarbonising the energy supply, and represents a key part of the German Energiewende. However, significantly increasing the share of renewable power in the energy mix implies coping with the natural intermittency of RES like wind and solar. RES development also does not directly address non-electric energy needs such as fuels for transportation and industry feedstock, which are presently relying on fossil fuels. Therefore, the conversion of surplus renewable electricity (RES-E) into the more convenient form of a liquid or gas (power-to-liquid and power-to-gas) could help offset RES intermittency while providing a diverse mix of energy carriers. If recycled CO 2 is used in the fuel synthesis process, overall emissions can be greatly reduced. This paper aims to sketch the possible contribution of RES-E combined with power-to-gas (PtG) and power-to-liquid (PtL) schemes in the 2050 German energy system, by modelling an increase in installed renewable power. Different scenarios are laid out and compared, and the results are utilised in a basic economic assessment of the fuel production cost for an hypothetical power-to-liquid plant.
