Weaving our energyscapes: Using hydrogen to store renewable energy in a network composed of existing threads

This project aims to address the challenges posed by the transition to renewable energy sources. This will cause an unstable and unreliable energy flow, which does not correspond with the current energy use patterns of society. Different elements of the current energy network are analysed. They have a big role in the transition towards a...

Modelling alkaline silicon-air batteries: A finite element model

Renewable energy sources such as solar and wind energy rely on climate­ and weather conditions, like sun irradiation in the case of solar energy, and wind speed in the case of wind energy. These change throughout the day and with the seasons. There are periods of little wind, and during the night there is no sunlight. During periods of no...

Feasibility study of novel seasonal energy storage technologies for residential systems

The growing global energy demand and correlated rise in carbon emissions is forcing us to increase the use of renewable sources. The residential sector represents a large part of the total energy consumption, and European governments are investing in distributed PV to increase the renewable share in this sector. However, on top of the solar...

Hourly Matching of renewable electricity production with demand of large-scale electricity consumers

This research aims to provide a method for large-scale commercial electricity consumers to procure towards 100% hourly matched renewable electricity. A problem with the current electricity balancing system is that the energy produced by Variable Renewable Energy sources (VRES), such as wind and solar PV, has a weather-dependent production...

Offshore wind + Energy Storage: Selection and design of energy storage for the integration of offshore wind energy in the future Dutch electricity system

The Dutch government has set out to largely reach reductions in carbon emissions in the electricity sector with the utilization of offshore wind energy. Due to the intermittency of wind energy this poses new problems and challenges for the future electricity system in the Netherlands. The objective of this report is to identify the challenges...

The Energy Transition and Policy Options for the Need of Flexibility: A Case Study of CCGT Generation in Germany

National policies that seek to stimulate the energy transition require attention with the requirement for generation sources that can compensate for moments when wind and solar plants are not available. Electricity supply needs to adjust to demand in real-time, at least until energy storage becomes commercially viable, otherwise the energy...

A PV Powered BWRO Desalination Installation with Energy Recovery and Hydro-Pneumatic Energy Storage

This MSc. Thesis project was performed at the Sanitary Engineering Department of the TU Delft as part of the Sustainable Energy Technology program. It is one of the unique research projects performed in the field of renewable driven Reverse Osmosis desalination, producing fresh water with only renewable energy sources as driving force. With the...
