Fischer-Tropsch products from biomass-derived syngas and renewable hydrogen

Global climate change will make it necessary to transform transportation and mobility away from what we know now towards a
sustainable, flexible, and dynamic sector. A severe reduction of fossil-based CO2 emissions in all energy-consuming sectors will
be necessary to keep global warming below 2 °C above preindustrial levels. Thus, long-distance transportation will have to
increase the share of renewable fuel consumed until alternative powertrains are ready to step in. Additionally, it is predicted that
the share of renewables in the power generation sector grows worldwide. Thus, the need to store the excess electricity produced
by fluctuating renewable sources is going to grow alike. The “Winddiesel” technology enables the integrative use of excess
electricity combined with biomass-based fuel production. Surplus electricity can be converted to H2 via electrolysis in a first step.
The fluctuating H2 source is combined with biomass-derived CO-rich syngas from gasification of lignocellulosic feedstock.
Fischer-Tropsch synthesis converts the syngas to renewable hydrocarbons. This research article summarizes the experiments
performed and presents new insights regarding the effects of load changes on the Fischer-Tropsch synthesis. ... mehrLong-term campaigns
were carried out, and performance-indicating parameters such as per-pass CO conversion, product distribution, and
productivity were evaluated. The experiments showed that integrating renewable H2 into a biomass-to-liquid Fischer-Tropsch
concept could increase the productivity while product distribution remains almost the same. Furthermore, the economic assessment
performed indicates good preconditions towards commercialization of the proposed system.
