Ammonia is heavily used in agriculture as a fertilizer and in industry as a raw material for the production of various organic nitrogen compounds. Its high hydrogen content and its established infrastructure for both storage and distribution makes ammonia a prominent candidate for storing fluctuating …

Energy usage is a fundamental property of injection molding machines. The development of these machines is accompanied by two contradictory objectives. On the one hand, a producer wants to produce as quickly as possible, cycle times must be as short as possible, and the number of products produced simultaneously …

Scholars in sustainable consumption increasingly highlight the limitations of “weak sustainable consumption” approaches to overcome the challenges of the current environmental crisis. While efforts to enable cleaner production and circular flows of materials are necessary and important, progress in environmental …

Renewable energy systems are a crucial technological development needed to combat climate change. This thesis covers the design and implementation of a mathematical optimization model, which calculates the lowest cost of hydrogen for certain renewable energy system configurations. The output of the model …

This is the introduction to a special issue on media and transgression, one of early cultural studies’ key terms. It inquires into the uses of transgression as a critical concept to query contemporary media culture which is discussed in six case studies: on political satire, Mukbang, cult drama, the …

Market information is important to farmers because it helps them to make optimal production and marketing decisions. This study focused on the development of a practical and operational strategy that increases market information access for soybean small holder farmers, consequently improving access to …

tract Micro wind turbines can be structurally integrated on top of the solid base of noise barriers near highways. A number of performance factors were assessed with holistic experiments in wind tunnel and in the field. The wind turbines underperformed when exposed in yawed flow conditions. The theoretical …

The Power to Flex project aims to promote the development of storage possibilities from sustainable energy sources. Hydrogen is opted to be a feasible energy carrier, which can also be stored for prolonged times without further losses and can be transformed into electricity and heat when needed. Producing …

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 …

With the effects of climate change linked to the use of fossil fuels, as well as the prospect of their eventual depletion, becoming more noticeable, political establishment and society appear ready to switch towards using renewable energy. Solar power and wind power are considered to be the most significant …
