Maximizing biofuel production in a thermochemical biorefinery by adding electrolytic hydrogen and by integrating torrefaction with entrained flow gasification. Energy, 85, 94-101. DOI: 10.1016/j.energy.2015 Maximizing biofuel production in a thermochemical biorefinery by adding electrolytic hydrogen and by integrating torrefaction with entrained flow gasification AbstractIn a "conventional" thermochemical biorefinery, carbon is emitted from the plant in the form of CO2 to make the synthesis gas from the gasifier suitable for fuel production. The alternative to this carbon removal is to add hydrogen to the plant. By adding hydrogen, it is possible to more than double the biofuel production per biomass input by converting almost all of the carbon in the biomass feed to carbon stored in the biofuel product. Water or steam electrolysis can supply the hydrogen to the biorefinery and also the oxygen for the gasifier. This paper presents the design and thermodynamic analysis of two biorefineries integrating water electrolysis for the production of methanol. In both plants, torrefied woody biomass is supplied to an entrained flow gasifier, but in one of the plants, the torrefaction process occurs on-site, as it is integrated with the entrained flow gasification process. The analysis shows that the biorefinery with integrated torrefaction has a higher biomass to methanol energy ratio (136% vs. 101%) as well as higher total energy efficiency (62% vs. 56%). By comparing with two identical biorefineries without electrolysis, it is concluded that the biorefinery with integrated torrefaction benefits most from the integration of electrolysis.

“…In [11], the biofuel is synthetic natural gas (SNG). In [13], it is Fischer−Tropsch fuel. The novelty of the present paper is the detailed design and analysis of the proposed biorefineries as well as using the electrolytic hydrogen for chemically quenching the hot gas from an entrained flow gasifier.…”

“…Previous work within this field of integrating gasification and electrolysis for synthesis of fuels or chemicals include [1][2][3][4][5][6][7][8]. The biofuels produced in these references are: methanol [1,[4][5][6][7], Fischer-Tropsch fuels [2], synthetic natural gas (SNG) [3], and dimethyl ether (DME) [8]. Liquid water electrolysis is used in these studies, except for [2,8], in which steam electrolysis is used instead.…”

“…If solid oxide cells (SOC) are used for steam electrolysis (SOEC), these cells can also be used as fuel cells (SOFC) for electricity production, when the electricity production from renewables is low. Systems combining gasification and SOCs have been studied in numerous articles for either electricity production (Bang-Møller et al, 2011;Gadsbøll et al, 2017;Omosun et al, 2004;Panopoulos et al, 2006) or fuel production (Bernical et al, 2013;Clausen, 2017), but few studies look at both electricity and fuel production and investigate the potential of such polygeneration systems or flexible biorefineries (Fig. 11).…”

Thermal gasification is a very relevant technological platform to assess in relation to production of carbonnegative bioenergy from plant materials as it offers high feed and product flexibility combined with highenergy efficiency. Many different biomass feedstock and organic secondary resources can be converted into a wide variety of products such as heat, electricity, chemicals, transport fuels and high-value ash and char products. The platform is undergoing fast development, and industry and academia work together to optimize the process performance, increase fuel and product flexibility as well as combine different technologies to increase the efficiency, economic viability and product yield and value. This chapter provides insight on the versatility and potential benefits of biomass gasification and the related biobased products. General key issues of gasification plant designs are discussed, and a series of new concepts and solutions within process integration schemes, polygeneration strategies and biochar uses are described.
