High-pressure anaerobic digestion is an appealing concept since it can upgrade biogas directly within the reactor. However, the decline of pH caused by the dissolution of CO2 is the main barrier that prevents a good operating high-pressure anaerobic digestion process. Therefore, in this study, a high-pressure …

It is of utmost importance to collect organic waste from households as a separate waste stream. If collected separately, it could be used optimally to produce compost and biogas, it would not pollute fractions of materials that can be recovered from residual waste streams and it would not deteriorate …

Power-to-gas technologies are considered to be part of the future energy sys- tem, but their viability and applicability need to be assessed. Therefore, models for the viability of farm-scale bio-power-to-methane supply chains to produce green gas were analysed in terms of levelised cost of energy, energy …

The 'AgroCycle' project investigates whether a cooperation of farms can become self-sufficient in energy and fertilization by using manure and organic waste streams for the production of energy, green fuel and green fertilizers by means of anaerobic digestion (AD). In the project, the project partners …

Research presentation at Sustainable Entrepreneurs Networking Event on new biogas technology and its valorization opportunities in collaboration with Mr Maik van Heerd (Progress Events), professor Jan-Peter Nap (Hanze UAS), Mr Ruud Paap (New Energy Coalition)

Poster presentation at Let’s Gro Groningen, on the opportunity for inner-city production of biogas within a circular restaurant concept at the Boterdiep, Groningen, in collaboration with Mr Maik van Heerd (Progress Events), Mr Geert Greving (Groningen Gist), Mr Ruud Paap (New Energy Coalition), Thomas …

Researchposter which describes a researchproject supervised by dr. ir. A.J. Smit. The main goal of this project is to develop business model patterns for the economic viable production of biogas for restaurants and breweries. Actual projects with breweries in Groningen are used to collect data in order …

This study was conducted to investigate dairy farming practices and gross margin at smallholder dairy farmer level to design a business model for scaling up climate-smart dairy in Ziway-Hawassa milk shed. 80 sample dairy farmers from five districts (which then categorised as urban and peri-urban dairy …

Wind and solar power generation will continue to grow in the energy supply of the future, but its inherent variability (intermittency) requires appropriate energy systems for storing and using power. Storage of possibly temporary excess of power as methane from hydrogen gas and carbon dioxide is a promising …

Power to methane provides a solution to a couple of two problems: unbalanced production and demand of wind plus solar power electricity and the low methane content of biogas by storing electricity via hydrogen into methane gas using carbon dioxide from biogas and methanogenic bacteria. The four-year …
