Andreas Hornung holds 21 patents and has published more than 340 scientific publications to date. The main strategic topic of Hornung’s work today is the development of decentralized power providing units combined with pyrolysis, gasification and digestion units – called the Biobattery.In a biogas scenario, a Biobattery installation seeks to use peaks in energy supply to add to the energy output from a biogas installation and enable the thermochemical transformation of the more recalcitrant lignin based components of digestion feedstocks. The use of digestate solids as feedstock for intermediate pyrolysis means that the amount of digestate for application to land is reduced to the liquid fraction. This is desirable where there is an oversupply of nitrogenous materials for application to land such as in areas of intensive livestock production, since digestates can be a source of both greenhouse gas emissions and nitrogen losses to water bodies. Hence, the Biobattery not only adds to the flexibility of energy supply and storage, it also increases the energy and financial gain achieved from existing biogas infrastructure, while reducing their environmental impact.
