Techno-economic evaluation of biomass-to-fuels with solid-oxide electrolyzer

Jan Van Herle, François Maréchal, Ligang Wang, Hanfei Zhang

Thermochemical biomass-to-fuel conversion requires an increased hydrogen concentration in the syngas derived from gasification, which is currently achieved by water–gas-shift reaction and CO2 removal. State-of-the-art biomass-to-fuels convert less than hal ...

Techno-economic comparison of green ammonia production processes

Jan Van Herle, François Maréchal, Ligang Wang, Hanfei Zhang

To reduce the fossil-fuel consumption and the impacts of conventional ammonia production on climate change, green ammonia production processes using green hydrogen need to be investigated. For commercial production scale, potential alternatives can be base ...

Techno-economic optimization of biomass-to-methanol with solid-oxide electrolyzer

Jan Van Herle, François Maréchal, Maria del Mar Perez Fortes, Ligang Wang, Hanfei Zhang

The purpose of this paper is to assess techno-economically the integration of solid-oxide electrolysis in biomass-to-methanol processes: (1) The hydrogen produced by electrolysis can be used to adjust the composition of syngas from gasification to increase ...

Power-to-methane via co-electrolysis of H2O and CO2: The effects of pressurized operation and internal methanation

Stefan Diethelm, Jan Van Herle, François Maréchal, Tzu-En Lin, Ligang Wang, Hanfei Zhang

This paper presents a model-based investigation to handle the fundamental issues for the design of co-electrolysis based power-to-methane at the levels of both the stack and system: the role of CO2 in co-electrolysis, the benefits of employing pressurized ...

Techno-Economic Optimization of CO2-to-Methanol with Solid-Oxide Electrolyzer

Jan Van Herle, François Maréchal, Ligang Wang, Hanfei Zhang

Carbon capture and utilization are promising to tackle fossil-fuel depletion and climate change. CO2 hydrogenation can synthesize various chemicals and fuels, such as methanol, formic acid, urea, and methane. CO2-to-methanol integrated with solid-oxide ele ...
