Feasibility of coupling hydrogen and methane production during sewage sludge digestion

Ellacuriaga M., Aguilar-Pesantes A., (Corresponding) Gómez X.

Topic:

Energy technologies and sustainability

Anaerobic digestion is a technology widely used for the stabilisation of sewage sludge in wastewater treatment plants (WWTP). This technology presents several advantages such as the production of energy and the use of this energy to cover the demand of the treatment plant. However, sludge digestion...Read more

Utilization of paraffin wax as phase change material for solar thermal energy storage

(Corresponding) Shalaby S., Kabeel A., Fleafl A.

Topic:

Energy technologies and sustainability

In this work, a thermal energy storage system based paraffin wax as phase change material (PCM) was designed, constructed and tested when it was integrated with a solar water heater (SWH). For the purpose of comparison, the SWH was also tested when water was used as a storage medium. The system was...Read more
