Applications
of the biomethane

Biomethane in the fuel
filling stations

GM upgrading unit can be joined to new or existing fuel filling stations. The biome thane can be mixed with the fuel methane from the NG achieving the mixing target required by the biofuels. Furthermore the biome thane can be easily stored and transported to the filling stations not connected to the natural gas grids.

Biofuels
comparison

Nowadays the vehicles utilizing the methane from NG as fuel are achieving a reduction in the emissions by 21% and 24% respectively compared to the diesel and petrol fuel. In the near future the motors fed with a mixing of biomethane and NG can achieve a further 19% reduction in the emissions. The emissions in a vehicle fed with 100% of biomethane are 5 gr CO₂ eq/km only as the electric vehicles.

for fossil fuels profitability reducing the dependence from the import.
For the above the grid injection of the biome thane is worthy to be considered.

The higher energy efficiency of the biomethane compared to the biogas is even more important considering that, in many decentralized biogas production units, the waste heat from the cogenerator can be not profitably recovered.

Reuse of

The carbon dioxide (CO₂) off-gas from the GM upgrading unit is at high purity containing 99.90% of CO₂ (dry basis). Instead of being vented after treatment, as it is normally done with the upgrading
