n the work package described in this report, members are investigating whether a cooperative of farmers can become self-sufficient in energy and fertilization by using manure and organic waste flows in combination with anaerobic fermentation. The aim is to link the nutrient cycle (from manure to digestate …

Materials with semiconducting properties are present in every microelectronic device and form the backbone of our information society. Commonly used inorganic semiconductors are poorly modular and their production is expensive and energetically demanding. Moreover, the use of metals and critical raw …

The local Dutch legislations (PGS-29) regarding the above-ground storage of flammable products have become stricter. This has led to the phasing out of Viking-Johnson couplings that are located inside of tank pits. These couplings are prone to leakage and they use rubber seals which are now prohibited …

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 …

The future energy system could benefit from the integration of independent gas, heat and electricity infrastructures. Such a hybrid energy network could support the increase of intermittent renewable energy sources by offering increased operational flexibility. Nowadays, the expectations on Natural Gas …

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 …

This research has been executed on behalf of the shipping company Hartman Seatrade. This research has been done due to the new rules of the IMO (International Maritime Organisation), according the sulphur emissions of ships. In 2008 is decided that from the year 2020, sulphur emissions for ships are …

The future energy system could benefit from the integration of the independent gas, heat and electricity infrastructures. In addition to an increase in exergy efficiency, such a Hybrid Energy Network (HEN) could support the increase of intermittent renewable energy sources by offering increased operational …

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 …

Wind and solar power generation will continue to grow in the energy mix of the future, but its inherent variability (intermittency) requires energy systems for storing electricity. Storage of electricity as methane from (bio)hydrogen gas and carbon dioxide is considered an interesting option. The surplus …
