It is a step in the right direction. At the moment the recognition is “only” valid for heating systems. The next step would be the approval for vehicles and machines. CombiFuel® very much welcomes this positive development.
Here the report from www.fluessiggas-magazin.de:
The new building energy law (GEG) came into force on 1 November. It includes biogenic liquid gas, or BioLPG for short, as an energy alternative for new buildings. Combined with conventional condensing boiler technology, biogenic liquefied gas now meets the use requirements for renewable energies specified for new buildings. This is a historic step for the innovative fuel, which in Germany is currently only offered to customers by the Krefeld energy supplier Primagas.
The GEG, which was passed in the summer, came into force on 1 November 2020 and regulates the legal requirements for heating systems in new buildings.
It mentions biogenic liquid gas in the same breath as energy from sun, wind and water, thus underlining the fuel’s great sustainable potential.
What is biogenic liquid gas?
Biogenic liquefied gas is produced from renewable raw materials and organic residual and waste materials. These include used cooking fats from the food industry, for example. Those responsible are constantly looking for other potential raw materials from which biogenic liquefied gas can be produced – so that one day they will be able to do without renewable raw materials altogether. “Against this background, biogenic liquid gas is available in the long term, crisis-proof and a reliable prospect for a green future,” explains Jobst D. Diercks, Managing Director of Primagas. “It is therefore the alternative to heating oil, especially in rural regions where there is no connection to the natural gas grid”. BioLPG as well as conventional liquefied petroleum gas are approved even in water protection areas because they burn almost without residue.
BioLPG with new primary energy factors
For use in condensing boilers with a BioLPG share of at least 50 %, the primary energy factor (PEF) is 0.7. For use in a CHP plant with a share of at least 30 %, the PEF for BioLPG was set at 0.5. In addition, the legislator recognises in the JIT that Primagas offers the biogenic energy source by means of mass balancing.
Conventional liquefied gas is now also better evaluated: The new PEF of 0.6 applies when used with a CHP plant in a neighbourhood solution where several buildings are supplied simultaneously.
A milestone for biogenic liquid gas
“Inclusion in the JIT is an important step in the history of biogenic liquefied gas,” emphasises Jobst D. Diercks. “Recognition of the energy source in the context of the obligations to use it for new buildings will also pave the way for its use in existing buildings in the long term. The signal is clear: this fuel has a future!
