Bio Gas needs backup solutions

Bio gas without supercooling to LBG (Liquified Bio Gas) cannot be stored in large amounts. This create a challenge when it comes to safety of delivery. To be able to deliver bio gas to transportation or other end consumers require that the deliveries can meet the customers need at any time. Therefore, changes in production and consumption of bio-gas makes back-up solutions necessary. Natural gas is a scalable and reliable back-up source.

The difference between Bio Gas and Natural Gas

Upgraded Bio gas and natural gas both consist mostly of methane. Both are a result of decaying biological materials, as the natural gas has been trapped under the surface for millions of years it is not considered renewable. Bio gas is part of the natural organic cycle and is therefore considered renewable.

Natural gas as back-up to Bio Gas facilities

As both gases consist mostly of methane they are fully interchangeable and can use the same equipment without modifications. The user will not feel a difference between using natural gas or bio gas.
Barents NaturGass delivers natural gas as backup to several bio gas facilities. Normally this mean that we build a normal LNG facility as we would for an industrial customer, consisting of a vacuum insulated steel tank, vaporizer, pressure regulators, and a meter. Barents NaturGass will deliver LNG to the customers storage tank as needed.
In bio gas backup solutions, the gasified LNG normally runs to a compressor near a filling station. There it will be combined with bio gas and compressed to around 200 bars. We call this CNG (Compressed Natural Gas) and CBG (Compressed Bio Gas). Vehicles can fuel at these filling stations. The operator of the filling stations controls the mix between bio gas and natural gas within defined parameters and depending on availability and price.
