Anaerobic Digestion in Germany & AD Industry Growth Prospects from EEG 2021 Act

Anaerobic digestion in Germany is forecast to expand. There is good reason to be optimistic about the prospects of growth in the German anaerobic digestion industry due to the passing of the new 2021 Renewable Energy Sources Act (EEG) by the Bundestag, which took place just before Christmas 2020.

This promises to be a major step towards a substantial increase in biogas generation in Germany, benefiting not only the AD industry but also contributing to the nation's action against climate change.

Anaerobic Digestion in Germany and Growth Prospects for the German Biogas Industry

Anaerobic digestion is transforming the energy landscape in Germany, carving out an important niche within the realm of renewable resources. This process harnesses natural degradation, when air is absent, to turn organic waste into biogas, effectively converting what was once merely rubbish into a beacon of sustainability.

The German Renewable Energy Act (EEG) 2021 has sent ripples through the nation's biogas sector, shaping how it contributes to the nation's power grid and challenging its growth trajectory. Boasting 50 TWh of final energy from biogas alone last year, Germany illustrates its commitment to a green transformation.

But the future for biogas in Germany, as elsewhere, hinges on legislative support; thus, navigating these policies becomes crucial for everyone, from municipal decision-makers to agricultural enterprises seeking sustainable solutions.

Read on for insights into how EEG 2021 could fuel or dampen Germany’s journey toward clean energy autonomy. Discover the potential that lies ahead!
