Ammongas aims to lead the global transition to a cleaner energy future by delivering smart, sustainable renewable gas treatment solutions that maximize resource recovery, minimize environmental impact, and empower circular energy systems worldwide.Vision statement
Founded in 2002
Ammongas was founded in 2002 by Anker Jacobsen, a chemical engineer who previously patented a stripper-absorber system in 1982 for recovering petrol vapors—a technology that later became the foundation for Ammongas’ biogas upgrading plants.
Background
After earning his M.Sc. in chemical engineering, Anker worked with ABB’s air purification division. He developed and successfully implemented stripper-absorber systems on multiple projects, including large-scale installations in Sweden and Norway

From Petrol Vapor to Biogas
In 2002, after selling his petrol recovery business and planning retirement, Anker saw an opportunity: apply his stripper-absorber principle to upgrade biogas. This led to the launch of Ammongas using the same underlying technology .
A Danish First
Ammongas quickly became a pioneer—building the first biogas upgrading plant in Denmark and expanding to serve clients across Scandinavia, Germany, Canada, and the U.S.

In it together
We enjoy collaborating to achieve the green transition – with our colleagues and everyone else who wants to be part of the journey. Focus for us is on solving the task – not on who is formally responsible. If you reach out to colleagues, they are always eager to help. When we see a problem – we solve it together. When we succeed, we celebrate together.

We are excited and passionate about our work, the journey we are on towards a greener planet and what we are achieving. The excitement is contagious – and we enjoy inspiring and being inspired by each other. We love what we are doing, and we have fun doing it.
Inclusion
We celebrate our differences – and we respect and appreciate the individual. You can be yourself and be accepted as you are.
Agility
We like to act quickly and smartly. We are open minded, willing to take risks and carefully consider all opportunities. We push the limits of the technologies we work with and ourselves. We think and act in non-bureaucratic ways and make decisions effectively.
Trust and courage
We have a high degree of trust between each other. We think creatively, think outside of the box and enter uncharted territory. We have a flat hierarchy with an open and honest dialogue, and we empower each other. When you have been given a mandate, we trust in your abilities.
Ambition
We want to become a global major in order to create a better world. We are driven to push each other in order to facilitate the green transition. We have a winner’s mentality – we do not give up before we succeed. To us it is about achieving together.
