Biogas

Biogas is a direct substitute for natural gas in national grids. Biogas certificates enable companies to make 100% renewable fuel claims and integrate clean energy into sustainability strategies. 

What is biogas?

Biogas is a combination of methane, CO2, and other gaseous substances obtained from the controlled decomposition of organic matter. Once cleaned or upgraded, it is turned into biomethane, a compound almost identical to the natural fossil gas that runs through national grids.    

Biomethane is virtually carbon neutral. As it grows, the biomass used to produce it captures CO2, which returns to the atmosphere during combustion and is then captured again by new biomass.   

Biogas is often called “green gas”, a broader category that includes other renewable fuels of non-biological origin such as green hydrogen and syngas.

How is biogas produced? Types of feedstock  

Biogas can be produced from differentorganic materials known as feedstock.  

  • Waste: Previously discarded organic materials, including sewage sludge, manure, and some kinds of biowaste. 
  • Crops: Plants with high yields specifically grown to produce gas, such as sugar cane, sorghum, and other woody crops.  
  • Sequential cropping: Two or more crops are grown in sequence on the same plot of land in a single farming year. Only one or a fraction of them is used as feedstock, preventing indirect land-use change.

How biogas certificates work 

Companies can document the consumption of biogas with Energy Attribute Certificates (EACs) issued through different certification schemes.   

Each MWh of biomethane injected into the grid is labelled electronically. This unique identifier contains information about where, when and how it was produced. Certificates guarantee that renewability claims are authentic and avoid the double counting of environmental attributes.   

Biogas certificates in Europe  

In the EU, biogas is included in the Guarantees of Origin (GOs) framework. There are currently different schemes for certification. GOs issued in the UK, Denmark, Germany, the Netherlands, and Austria can be transferred across borders. Other national registries for consumption in specific countries also exist.  

Biogas certificates in the United States  

In the US, the Environmental Protection Agency (EPA) and the California Air Resource Board (CARB) are working to forward the use of certificates of gaseous energy carriers.

Purchasing biogas certificates 

Ecohz simplifies how companies procure clean energy and provide them with the best energy mix according to their needs.  

  1. Based on your location and volume of consumption, we discuss how we can help you reach your renewable energy ambitions. 
  2. You receive an offer with a specific rate and expiry date. Upon acceptance, we secure the quoted price. 
  3. Once the offer has been accepted, we deliver a standardised contract. 
  4. We provide you with an invoice and documentation for reporting. 

Why purchase biogas certificates 

Biogas certificates allow consumers to make 100% renewable gas claims and report reduced Scope 1 andScope 2 emissions. 

Beyond substituting fossil fuels and avoiding greenhouse gas contributions, renewable gas can add an element of circularity to sustainability strategies by transforming waste into energy. Purchasing biogas certificates further incentivises the renewable energy industry, making it more competitive and accelerating the transition.  

The price of biogas 

Multiple factors determine the price of biogas, mainly related to the country and the origin of the product. The type of feedstock is especially relevant, as biogas obtained from waste, associated with higher environmental benefits, is often priced higher than that obtained from crops.   

Changes in regulation, geopolitical events, and other variables can also influence the price of renewable fuels and the associated EACs. Ecohz constantly monitors market developments to provide the best up-to-date pricing.
