Natural gas blended with biomethane or synthetic gas (power-to-gas) from renewable sources can reduce CO2 emissions significantly, up to 95%.

Biomethane and synthetic gas (from the gasification and power-to-gas processes) are renewable energy sources with very low carbon footprints; when applied as fuels, they allow gas vehicles to run carbon-neutral.

Biomethane is refined from biogas produced by the natural breakdown of organic material in waste from agriculture, municipal waste, plants, sewage or food waste. It has the same composition as natural gas and can be injected into the natural gas distribution grid, or used directly by natural gas vehicles.

Power-to-gas means producing synthetic natural gas with surplus energy from wind farms or solar panels through a chemical process. It can be used directly by natural gas vehicles or injected into the natural gas grid.

NGVs can also use renewable hydrogen made from water electrolysis mixed with natural gas in the grid. Blending hydrogen with natural gas can bring additional benefits in terms of pollutant reduction.
