The renewables all-rounder
Biomethane upgrading opens up a promising future market for the biogas industry. With feed-in into the public natural gas grid, the green all-rounder is perfect for the decentralised supply of energy, offering a long-term replacement for fossil natural gas and driving the energy transition forward. What’s more, the biomethane manufactured in the gas upgrading plant has the exact same properties as natural gas, being just as flexible in its usage and easier to store than other energy sources. Plus, it’s renewable.

How is this valuable bio natural gas produced?
Anaerobic digestion of organic materials creates a gas composed of methane and carbon dioxide. To upgrade the biogas to natural gas-quality biomethane, the crude gas is first purified and compressed. The membrane technology we use then exploits the different sizes and permeation speeds of the two kinds of gas molecules involved: since carbon dioxide molecules are smaller than methane molecules, they can migrate through the membrane much more quickly. As a result, the methane remains on the high-pressure side, while the CO2 molecules in the biogas pass through. As a result, the gas upgrading needs neither chemicals nor water nor any other resources.
The starting point for producing biomethane doesn’t have to be biogas, however. After a preliminary purification stage, gas from landfill and wastewater treatment plants can also be used to produce biomethane.
The biomethane so produced is the all-rounder among renewable energy sources, and can replace fossil fuel-based natural gas anywhere it is used. On the following pages, you can find out about the many uses for this valuable and renewable natural gas, and how it can play a part in an environmentally-friendly energy supply system.

The advantages of biomethane at a glance:
FLEXIBILITY OF USE
Whether in the home, as a carbon-neutral fuel (CNG) for the transport sector or converted on-demand into electricity and heat, biomethane is a true all-rounder that can also be used in a decentralised system.
Biomethane frees us from our dependence both on fossil natural gas and natural gas importers, thereby helping to support predictable long-term pricing trends in domestic energy market.
EXCELLENT PUBLIC ACCEPTANCE
Biomethane is renewable. This means heating consumers benefit from an improved CO2 footprint and potential savings resulting from the more efficient use of energy. As a highly efficient fuel, biomethane is also a star performer in the fuel market and can help to reduce emissions many times over.
STRONG MARKET POTENTIAL
Since crude gas sources and gas grid infrastructure are both available, neither time nor capital investment is necessary to establish them. On the contrary: the use of biomethane can unburden the electricity network and contribute to a temporary easing of cost-intensive upgrading work.
REGIONAL VALUE CHAINS
Biomethane promotes economic growth both in the feed-in region – which is in the immediate vicinity of the gas generating plant – and in the consuming region, which is independent of the feed-in location.
AN ADDITIONAL PILLAR FOR YOUR BUSINESS
Since our gas upgrading systems are exceptionally efficient and cost-effective, they can offer biogas plant operators another attractive source of revenue from biomethane production.
