Integral techno-economic comparison and greenhouse gas balances of different production routes of aromatics from biomass with CO2 capture

The techno-economic performance and CO2 equivalent (CO2eq) reduction potential of bio-based aromatic production cases with and without CO2 capture and storage (CCS) have been evaluated and compared to those of fossil-based aromatic production. The bio-cases include tail gas reactive pyrolysis (TGRP), catalytic pyrolysis (CP), hydrothermal...

Potential role of natural gas infrastructure in China to supply low-carbon gases during 2020–2050

As natural gas (NG) demand increases in China, the question arises how the NG infrastructure fit into a low greenhouse gas (GHG) emissions future towards 2050. Herein, the potential role of the NG infrastructure in supplying low-carbon gases during 2020–2050 for China at a provincial resolution was analyzed for different scenarios. In total,...

Harmonized comparison of virgin steel production using biomass with carbon capture and storage for negative emissions

A harmonized method was developed to assess CO2 mitigation performance and avoidance costs for different steel production routes, including blast furnace with blast oxygen furnace (BOF), direct reduced iron (DRI) production with electric arc furnace (EAF), and Hisarna with BOF. Mass and energy balances were used to evaluate each route's cradle...

Decision making on regional energy transition. Models, tools and approaches

Since the industrial revolution we have relied heavily on fossil fuels as feedstock and energy source. A major drawback in using fossil fuels is the emission of anthropogenic greenhouse gases. Deep reductions in these greenhouse gas emissions are needed if climate change is to be limited to 1.5-2°C above pre-industrial levels. These reductions...
