Liquefied Sunshine: Transforming Renewables into Fertilizers and Energy Carriers with Electromaterials

Perspectives for alternative energy carriers based on renewables from technical and energetic point-of-view

Alternative energy carriers (AEC), based on renewable CO2-poor or CO2-free sources of energy, are of central importance for the transition towards a sustainable energy system. The most important AEC currently discussed are: hydrogen and electricity from renewable energy sources and other AEC based on biomass. The core objective of this paper is to provide an appraisal of the prospects of these ...

Energy in buildings: Efficiency, renewables and storage

— This lecture summary provides a short but comprehensive overview on the “energy and buildings” topic. Buildings account for roughly 40% of the global energy demands. Thus, an increased adoption of existing and upcoming materials and solutions for the building sector represents an enormous potential to reduce building related energy demands and greenhouse gas emissions. The central question is...

Renewable Energy Policy Considerations for Deploying Renewables

Optimal energy management for industrial microgrids with high-penetration renewables

This paper presents a day-ahead optimal energy management strategy for economic operation of industrial microgrids with high-penetration renewables under both isolated and grid-connected operation modes. The approach is based on a regrouping particle swarm optimization (RegPSO) formulated over a day-ahead scheduling horizon with one hour time step, taking into account forecasted renewable energ...

Polyurethane from Liquefied Wheat Straw as Coating Material for Controlled Release Fertilizers

A new controlled release fertilizer was developed by coating urea particles with bio-based polyurethane. Coating materials were synthesized from liquefied wheat straw, isocyanate, and castor oil. The effects of liquefied solvents, mass ratio of liquid to solid, size of wheat straw, and reaction time during liquefaction process on the nitrogen release rate of polyurethane-coated urea (PCU) were ...
