NextGenBiogas – Flexible production of bioenergy can contribute stability for power grids

If biogas, as a renewable source of energy, is to become an integral part of a future energy system that comprises a concept for flexible electricity generation, this will require the on-demand availability of bioenergy. As part of the NextGenBiogas collaborative research project, Fraunhofer IGB is developing a flexible process for the production of biogas on demand.

If biogas is to play an integral part in any future energy system, it is vital to find ways in which it can be produced on a flexible basis and thereby made available on demand. This will also help secure the viability of biogas as a renewable, biogenic source of energy.

The objective of the NextGenBiogas collaborative research project is to develop a flexible process for the production for biogas on demand for the purposes of flexible power generation. Use of bioengineering methods in a two‑stage process will make it possible to ramp up methane production significantly more quickly than is possible with current technology and research. Instead of using the substrate or the actual biogas as an energy‑storage medium, the energy is stored in the form of easily convertible organic acids – e.g. acetic acid – which are produced in the first stage of the two‑stage biogas process. In parallel, the microbiome is being characterized by means of next‑generation sequencing.

The project promises to bring the following benefits: optimization of biogas production, higher process stability, reduction of required gas storage capacity, increased security, and extra stability for the power grid. It will pave the way for a flexible production of bioenergy on demand.
