Steam Gasification of Carbonaceous Feedstocks via a 1.5 kWth Hybrid Solar/Autothermal Reactor

Sophia Haussener

A continuous method of steam gasification through hybridization of a solar reactor with an autothermal gasification process is proposed and tested. The ability to autothermally gasify a carbonaceous feedstock within a solar reactor enables round-the-clock ...

Trade-off designs of power-to-methane systems via solid-oxide electrolyzer and the application to biogas upgrading

François Maréchal, Jan Van Herle, Stefan Diethelm, Ligang Wang, Guillaume Jeanmonod

Solid-oxide electrolyzer based power-to-methane is promising for large-scale energy storage as well as biogas upgrading by efficiently converting intermittent renewable power and CO2 (e.g., in biogas) into synthetic methane. Either air or pure oxygen can b ...

Optimal design of biomass supply chains with integrated process design

François Maréchal, Theodoros Damartzis

The current work focuses on the optimal design of biomass supply chains, addressing the conversion of raw materials into useful services. The latter include not only heat and power but also synthetic bio-based fuels (e.g. bio-SNG). Optimally pre-designed p ...
