What level of GHG gas emission cost in transport makes gasification-based biofuel production systems profitable?

Gasification-based biofuel production systems have a large potential to contribute to climate change mitigation in the transport sector. The commercial feasibility of renewable energy technol­ogies is affected by fossil fuel prices, the price of biomass and policy instruments, e.g. a CO2e cost.

Kristina Holmgren, IVL, has lead a project that has aimed to analyze and quantify the level of a sector specific greenhouse gas (GHG) emission cost (CO2e cost) in transport required for making gasification-based biofuel pro­duction systems profitable under different future energy market scenarios. 

The results show that this level is not higher than the current level of CO2 tax in Swedish transport sector. The results also show that the systems where the biomass is used for electricity production and in battery electric vehicles, BEV, have higher profitability than the gasification-based systems. However, the electricity –based systems have a stronger dependency on heat sinks and a high price for delivered heat.

The main outcome and full presentation of results from the project is documented by a manuscript submitted for scientific publication in Energy. Until then, results are summarized in an f3 report available here. Additional funding for the project has been provided by Göteborg Energi foundation for research and development.
