Why upgrade

Upgraded biogas, biomethane, ensures optimal utilisation of the raw biogas as it can be utilised, amongst others, in the natural gas grid. This means that it can be used when and where it is needed instead of being burned and wasted.

Upgraded biogas is also environmentally friendly, and can be used for transport, in cars, buses and trucks.

Environmental advantages

The actual environmental gain is approximately 4 times bigger than the direct displacement of fossil CO2. At the same time, there is a significant advantage in the reduction of obnoxious smells, better utilisation of the nutrients in manure, as well as the ground enhancing ability achieved by returning the humus substances to the soil.

Green policies in EU

Results from a 2017 survey from the European commission, protecting the environment is important for 94% of Europeans. The challenge is to integrate environmental sustainability along with economic growth and welfare through separating environmental degradation from economic growth and achieving more with less.

Denmark as a pioneer country

According to the World Bank, Denmark is the leading country when it comes to renewable energy. The unique readjustment of the Danish natural gas grid to biogas, leading in Europe, plays a big part in this. A position that both politicians and the industry itself aspire to maintain.

By making an effort now we can ensure our descendants a green earth. Amongst others, we can do this by transforming our organic waste into biogas that also helps to ensure healthy farmland in the long run. The step further is to upgrade the gas, so we can replace the fossil fuels, this is the part Ammongas is working on, so we can ensure our children and their children a greener earth, a vision worth working towards.

Our clients need solutions that are tailored to their exact needs and maintains a high up-time. To ensure this, we have thorough alignment of expectations from the very beginning of our talks with clients so that we warrant that their needs are met in our design. We are present during the entire building phase and our offer for a service agreement after end running-in of the plant helps to ensure an optimal up-time, something that has always been important for me.
