A study on Biogas Liquefaction and use of Liquid Biomethane

The report is prepared as part of Biogas 2020, Go‐LNG and Future Gas projects, in a joint effort by Samsø Kommune, Biogas Østfold and Danish Technical University. The work has been co‐funded by these projects and the Interreg ØKS, Interreg BSR, Central Denmark Region and The Danish Innovation Fund.

This report is a brief introduction to the emerging field of cooperation between biogas produces and users of Liquid Biomethane. Environmental concern and regulations are the basis behind the emerging market with Green House Gas emissions and sulphur and NOx emission from Shipping.

Liquid Natural Gas market is processing and marketing natural gas at large scale on the global market, whereas the Liquid Biomethane markets is by nature comparatively on very small scale and often a local market, challenging the technologies and the economy of scale. However, the European market – giving timulations for biofuel blending from 2021 according to a new Transport Energy directive under negotiations – is expected to grow fast.

Several companies have prototypes and few biomethane liquefaction plants are running, and this report gives an overview of the technologies and some of the basic environmental, technical, economical and social aspects that must be considered for implementing the sustainable value chain for Liquefied Biomethane. The report has focus on marine transport, such as ferries, but LBM can also be used for heavy duty trucks and trains.
