Energy-environment-economy(3E) assessment of a novel low-carbon emission process integrating coalto- methanol with green hydrogen

Abstract
Methanol is an alternative fuel that offers convenient storage, transport and utilization, hence has attracted many attentions recently. Coalto-methanol (CTM) is a mature, inexpensive industrial process for methanol production, yet accompanied with large CO2 emissions and low C conversion rate due to the mismatch of H/C ratio between feedstock and product. In this study, a novel low carbon process of the CTM coupled with green hydrogen is proposed, in which the water gas shift (WGS) sector is replaced by water electrolysis based on solar power for adjusting the hydrogen carbon ratio ...
