“…3.6.1 LCAs. We found 11 BECCS LCA studies which matched our search terms, [163][164][165][166][167][168][169][170][171][172][173] see the overview table of BECCS studies in the ESI. † Most LCA studies exhibited negative GHG emissions from BECCS systems, although there were system layouts, which resulted in positive GHG emissions, mainly due to upstream activities such as feedstock production, solvent preparation 168 and also side-effects (e.g.…”

“…CDR technology systems are characterized by their variety of system layouts and value chains. For example, BECCS systems include the use of novel feedstock like algae, 172 different power plant configurations and blending ratios of biomass and fossil energy carriers 167 as well as the production of hydrogen from biomethane with CCS. 169 This large variety needs to be thoroughly addressed in further LCA.…”

“…Distributed biomass fuel utilization often does not have the operating conditions for carbon capture, and it has significant particulate emissions like PM2.5 and PM10. [ 16 ] Therefore, many research projects have used large‐scale bioenergy generation with carbon capture and storage systems (BECCS), [ 51–53 ] which can couple with carbon capture and storage technology.…”

“…Natural gas can also combine with biomass as an important transition fuel, further abating emissions. [53] However, natural gas is not the main fuel in China's energy infrastructure, which is predicted to last for a long time. [54] In addition, compared with the general supply of power grids, China's current natural gas pipeline network construction is still insufficient especially when facing gas storage and peak shaving matching scenarios.…”

important to meet China's overall goal for reducing carbon emissions. Among the energy consumption in industries, more than 50% of the energy is used in the form of heat [7] and the high-temperature steam is the most widely used heat carrier (see Note S2 in the Supporting Information), which is mainly supplied by industrial boilers. [8] These boilers produce 1.3 Gt CO 2 and are responsible for 33% and 27% of total soot and SO 2 emissions in China, [9] respectively. As can be easily seen, industrial boilers contribute significantly for major energy users, and are one of the key sources of greenhouse gas emissions and air and water pollution in China. [10] Recently in China, small-sized coal-fired boilers have been gradually restricted (see Table S2 in the Supporting Information). Current alternative boilers are oil-fired, gas-fired, electric, biomass, solar boilers, and some other less-common boiler types, each with its advantages, drawbacks, and obstacles for use in certain application. With oil-fired and gas-fired boiler, [11-12] the corresponding pollutants produced by the combustion process are inevitable. Even with the cleaner gas-fired boilers, [13] large amounts of carbon dioxide are emitted during combustion (even if less than with coal). Critically, gas-fired boilers are also faced with the problem of "gas shortages," especially in winter when the demand for residential heating is strong in the Beijing-Tianjin-Hebei region. [14] It is found that the biomass boiler has many economic, social and environmental benefits. [15] However, biomass fuels [16] are also characterized by high pollution-related contents including chlorine, high concentrations of alkaline materials, highly volatile components, and low ash melting points that make them easily produce slag and coke from combustion. Solar boilers [7,17] can collect solar energy to generate steam with low operating cost. However, solar boilers are usually with high initial cost due to the large collector area. For example, limited by the solar radiation intension about 1367 W m −2 , a 0.5 t h −1 solar boiler needs at least 200 m 2 of solar collector area. An additional shortcoming is that solar power is unavailable at night and is reduced on cloudy days. Therefore, at present, the application of water vapor generator using solar energy is mainly focused on the large-scale high-temperature steam power generation [18] and small-scale solar desalination conceptual design. [19-20] As for geothermal combined system, [21] waste heat boilers, [22] condensing boilers, [23] although they can offer energy savings With the ratification of the Paris Climate Change Agreement, the use of coal-fired boilers in China are being gradually restricted and removed from use to control air pollution and reduce CO 2 emissions. However, current alternatives to coal-fired boilers such as gas-fired boilers, electric boilers, biomass boilers, and solar boilers have obvious limitations and drawbacks that can limit the spread of their use. An air-source heat pump boiler that can extract...

“…Most of the existing literature related to BECCS deals with the power generation sector. [20][21][22][23][24][25] Some of the literature consider the addition of CCS In fuel production, albeit without much information on the environmental impact and the required policy framework necessary for the biofuel routes to be competitive with fossil fuels. Tagomori et al 26 performed a techno-economic assessment of FT-diesel production from eucalyptus and pine residues with the CCS case increasing production costs by 1%.…”
