The kernel of the project is the IFBB technology, developed in the University of Kassel.

At the initial stage the IFBB concept was based on the idea to improve the efficiency and to avoid the negative effects of biogas production.

The basic technological design was developed with PP11 in the early 2000s and tested on laboratory scale up to the year 2008. It has been successfully up-scaled (to 1:20) between 2009 and 2011 in the forerunner project PROGRASS funded by the LIFE+ programme.
By 2012 a first full-scale IFBB plant at the site of the PP6 in Baden Baden will be in operation.

All the scientific and technological tests on the demonstration level showed the high efficiency and the environmental friendliness of the approach beyond the basic advantages like production of storable fuel and nature protection side effects.

On basis of the positive experiences the project partnership decided in 2010 to take the next development step and to transfer the technology on a larger scale.

The technology providers (LP and PP11) have been collaborating for 2 years in the optimisation of the basic designs and settings. They decided to offer their sedentary and mobile IFBB technology for the sake of DANUBENERGY to promote the approach in central European riparian areas. In 2010 partners from DE, AT and SL formed a project development team and asked long-term cooperative partners (DE: SL, PL / AT1 (LP): HU and IT / AT2 (PP5): CZ and SK) to join.

The application was collaboratively elaborated on basis of different meetings and intensive communication in a joint development.
DANUBENERGY is designed to take the next development step of the eco-friendly IFBB-technology and to prepare large-scale investments in the participating CE regions.
