    Energy park & Donau-Silphie: a symbiosis that benefits nature

    Biogas plants that produce non-fossil fuels are very much in vogue at the moment. In the Swabian hamlet of Hahnennest, four family farms have joined forces to form an energy park and operate a local biogas plant, covering everything from substrate production to the sale of energy.

    In one cycle: ecopaper, energy and fertiliser made from Silphium perfoliatum

    Many consumers don't care about exactly how their paper packaging is made and what it is made of as long as it is "eco". But even producing recycled paper, trees need to be felled. An alternative could be paper made from cup plant. Together with partners, a company called Silphie Paper has developed concept for obtaining fibres for a new type of grass paper, while also producing heat, energy and nutrients for natural fertilisers.

    New technologies for using biogas as a balancing energy

    The microorganisms in biogas plants do a great job biologically converting CO₂ and hydrogen, which are primary fermentation products, into methane. Biomethane has a great future as an energy source. Scientists at the University of Hohenheim are investigating new ways to produce and use biomethane.

    NovoCarbo turns plant waste into biochar

    NovoCarbo GmbH produces biochar from plant residues such as wood chips, nutshells and manure. Different feedstocks, and the way these materials are processed, create biochars with different properties. This makes biochar suitable for different uses, including as a soil conditioner, in biogas plants or as bedding for stables and cowsheds. The Rhizo-Linse project is currently investigating whether biochar is also suitable as inoculant carrier for…

    Sensor networks are one of the keys to achieving digitalisation of the bioeconomy. Sensor networks are on the way to becoming important analysis and control instruments for energy-efficient and sustainable material cycles. Dieter Hertweck, Professor of Business Information Systems at Reutlingen University of Applied Sciences, shows what is already possible in digital agriculture and waste recycling and what is feasible for the future.

  • Wood energy – heating with wood – interview with Stefan Pelz, HFR - 10/02/2020 GW08-6743-2.jpg

    Wood: a cornerstone in energy transition

    While a good third of the electricity in Germany now comes from renewable energy sources, the production and supply of heat from renewables has stagnated at around 11.5 percent. Energy from biomass, mainly wood and biogas, accounts for over 80 percent of the renewable energy produced. Bioenergy municipalities show how locally available, renewable raw materials and solar power can be intelligently combined for supplying energy.

    Environmentally friendly alternative to fossil natural gas: methane from biomass

    In cooperation with the research unit of the German Technical and Scientific Association for Gas and Water (DVGW), KIT researchers have built a pilot plant in which biogas produced by fermenting residual organic materials can be upgraded to synthetic methane (synthetic SNG). Biobased methane is not only a sustainable energy source for the heating and transport sectors, but also opens up new opportunities for temporary storage of renewable…

    Residues from biogas plants as feed for algae

    Algae are frugal organisms. They require only light, water, minerals and carbon dioxide to be able to produce biomass. These properties will now be exploited economically in a two-year research project. Dr. Stefan Sebök from the University of Hamburg plans to study the holistic utilisation of degradation products of a biogas plant in Wallerstädten by linking them to land-based algae cultivation.

    Celeriac and electricity: dual-use system on arable land

    Food or fuel? Potatoes or electricity? In addition to growing energy crops for biofuel and biogas production, open space solar plants also compete with food production when it comes to land use. Agrophotovoltaics (APV), i.e. the dual use of arable land, can mitigate the conflicting interests of agriculture and open space PV systems. APV-RESOLA is a pilot project aimed at investigating the efficiency of this dual use.

    The number of biogas plants in Germany has increased almost tenfold since the start of the new millennium1. IBBK Fachgruppe Biogas GmbH, founded in 2000, has helped shape this development through training, consulting services and projects. Since 2015, the company has also been working on behalf of the Baden-Württemberg government to advise operators of existing and planned biogas facilities.

    Pleasant aromas from biogas

    Butyric acid is an important source of fruity aromas. It accumulates as an intermediary product during biogas production, from where it can be siphoned off and used for producing flavours. A new collaborative project aims to explore the technological and bioeconomic potential of extracting butyric acid from biogas plants.

    Biomass from algae and the wholesale market – a promising replacement for fossil raw materials

    Funding renewable energies is one of the EU’s key objectives. Biomass such as algae and organic waste are particularly promising because they are not in competition with food production.

    Flexible biogas plant operation – new concepts for stabilising bioenergy provision

    The lack of flexibility with regard to peak demand for electricity – both for consumers and producers – is a well-known problem as far as the production of electricity from renewable resources is concerned.

    Efficient production of fuel from biogenic residues

    Natural gas is a more climate friendly fuel than raw materials such as coal and petroleum. Nevertheless it is also a fossil fuel that generates anthropogenic CO2 emissions. In a collaborative project at the Karlsruhe Institute of Technology, scientists and engineers are concentrating on finding out how biogenic residues and waste materials such as wood, sewage sludge and biomass mixtures can be turned into alternative gaseous fuels.

    How efficient and climate-friendly is biogas production?

    Biogas plants have become a familiar sight in Baden-Württemberg's rural areas. It might therefore be expected that broad experience exists in the comprehensive evaluation of this type of energy generation from renewable resources or organic materials. However, scientists draw a very differentiated picture. It is difficult to make any generalisations, although the analysis of individual facets can provide further help.
