“…To deeply mitigate CO 2 emissions, the implementation of renewable bioenergy is a promising solution. One notable negative carbon technology in this regard was biochar technology, ,,, which had emerged as a prominent component of bioenergy with carbon capture and storage (BECCS) systems and had garnered significant attention. , Additionally, the IEA 2050 global energy system net-zero emission scenario analysis also pointed out that about 30% of global emission reductions would mainly come from BECCS . Consequently, the combination of CO 2 capture technology, renewable bioenergy, and carbon-negative technologies like biochar exhibits significant potential for deep decarbonization and the mitigation of CO 2 emissions within the methanol production sector.…”

“…26 Compared with other biomass wastes, such as straw and bagasse, SMS contains a larger amount of fixed carbon and less volatile matter, which makes it a prime candidate for the production of bio-based carbon. 27 The elemental composition of SMS was characterized by an elemental analyzer (Vario EL cube by Elementa). The moisture, fixed carbon, volatile matter, and ash compositions of SMS were obtained through proximate analysis, according to the Chinese standard method (GB/T 28731-2012).…”

Methanol production is a CO 2 -intensive process as its raw materials are mainly from fossil resources. Despite numerous proposed measures for CO 2 mitigation, selecting low-carbon options for methanol production still poses significant challenges. Here, we present an assessment approach based on their fossil energy demand (FED) and global warming potential (GWP). Specifically, four methanol production routes were first established based on the calcium looping sorption enhancement process, namely, coal to methanol, natural gas to methanol, biomass to methanol, and biomass to methanol with biochar (BTMC). Results show that appealing performances for FED and GWP of −17.085 MJ/kg-methanol and −2.457 kg-CO 2 -eq/kg-methanol were achieved in the BTMC process. Additionally, by tracking FED and GWP indicators, the lowest carbon footprint route (−5.793 kg-CO 2 -eq/kg-methanol) can be quickly identified when considering CO 2 capture, renewable energy, and feedstock substitution for existing processes. Overall, this work provides a new pathway for sustainable methanol production by evaluating low-carbon options from both energy and environmental perspective.
