Biogas hydrate – novel systems for upgrading, transportation and storage of biomethane

A general problem for biogas of vehicle fuel grade is cost- and energy efficient transportation and storage. One potential option could be to convert the biogas to gas hydrate, for further transport and upgrading to e.g. vehicle gas in a large scale. Hydrate is ice-like crystals that form at low temperature and high pressure.

The study has investigated the possibilities for formation of gas hydrates from biogas, by applying comparative system analyses with respect to economy and energy. The report includes a comparison of three scenarios for converting farm-produced biogas to vehicle fuel quality gas including conventional upgrading and transport in pressurized vessels and two future-oriented scenarios based on formation, transport and dissociation of gas hydrates.

The project wass financed by f3 Centre  (Swedish Knowledge Centre for Renewable Transportation Fuels).

Participating from the Department was Anders Larsolle and Åke Nordberg.

External partner was JTI - Swedish Institute of Agricultural and Environmental Engineering.
