Excess of renewable electricity from wind turbines or solar panels is used for electrolysis of water. To store this renewable energy as methane, the hydrogen is fed to an anaerobic digester to stimulate biological methanation by hydrogenotrophic methanogens. This workpackage focusses on the best ways …

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 …

Urban green and shading are adaptation measures that reduce urban heat. This is evident from meteorological measurements and investigations with surveys and has been described in many papers (e.g. Klemm et al., 2015). The cooling effect of these adaptation measures is reflected by lower air temperatures …

Thomas von der Dunk in de fout met zijn cultuurrelativisme.

Gear transmission systems are widely used in a variety of applications in many industries, including automobile, railway, wind energy and the shipping industry. A gearbox breakdown may result in catastrophic failures and significant economic losses. A gearbox fault can cause damage to a propulsion system …

The CDIO network works with the extended CDIO syllabus version 2.0 (Crawley et. al., 2011), in which two learning goal sections were added: leadership and entrepreneurship. This paper focuses on entrepreneurship and uses a case study of the Eye on Entrepreneurs (EoE) initiative in the Netherlands …

Recently, the Inverness, Ross and Skye forest district has had multiple occasions of wind damage in their forests. Because these were unpredicted and costly events, the model used to predict wind damage, ForestGALES, was analysed. Both input and output of the model were closely examined to discover why …

In certain conditions, (part of) an oil spill can disappear from the water surface through a process called natural dispersion. One available oil spill response option is to enhance this process by addition of dispersants (chemical dispersion). An informed decision for such response requires insight …
