A Porous Iron Electrode for Electrochemical Ammonia Synthesis

Ammonia is a precursor in fertilizer production and a potential carbon-free energy carrier, which is essential for the energy transition to more renewable energy sources. To that end, the current fossil fuel based method of industrial ammonia production through the Haber-Bosch process should be replaced by electrochemical ammonia synthesis....

Powering a Revolution: The Potential of Carnot Batteries in the Built Environment

The world needs reliable, sustainable, and longer duration energy storage solutions as the share of intermittent renewable energy increases in energy systems. Carnot batteries are a promising, emerging technological class of energy storage that store electricity in the form of thermal exergy. They can be made from abundant materials and existing...

Local Hydroelectric Energy Storage: A feasibility study about a small scale energy storage system combining hydropower, gravity power, spring power and air pressure

Renewable energy sources, like wind- and solar power, are expected to generate a greater part of the electricity production in the Netherlands each upcoming year. Besides all the advantages, the energy supply of these renewable energy sources fluctuates heavily as they mainly depend on the amount of wind and sun. Therefore, the electricity...

Analysing consumer perceptions towards the Tesla Powerwall in order to create future product acceptance

The energy transition is characterised by the growth of intermittent and thus non-steerable energy sources such as solar photovoltaic and wind. The technology development in the PV sector enables consumers to move beyond passive consumption of electricity towards becoming active producers of their own energy. This led to an increasing number of...

Improving the energy efficiency, emissions and maintenance costs of a deepwater DP-3 drillship by implementing an energy storage system in the energy distribution system

Deepwater drillships are nowadays capable of drilling to oil in water depths up to 4000m and reservoirs at 12000 m depth and greater. Active Heave Compensation at these large drilling depths and station keeping with the Dynamic Positioning system leads to large fluctuations in the electrical power system. The electrical power is now directly...

Failure mechanisms in lithium silicon batteries

Lithium silicon (Li-Si) batteries offer more than ten times the theoretical specific capacity compared to current lithium ion battery technologies, by using a silicon anode. In practice however, the cycle life of Li-Si batteries is very limited. The large volume change of the silicon anode is known to be the main reason for this. Research on the...

De maatschappelijke acceptatie van compressed air energy storage

Bachelorthesis waar de maatschappelijke acceptatie van de energie opslagtechniek compressed air energy storage (CAES) is onderzocht met behulp van Structural Equation Modeling. CAES kan als opslagtechniek bijdragen aan het verhelpen van de variabiliteit en onvoorspelbaarheid van een duurzame energievoorziening. Bij CAES wordt elektriciteit in de...

Pumped Hydro Storage: Pressure Cavern

The current Dutch electricity market is changing rapidly. New energy agreements demand 40% of Dutch electricity to be produced by renewable sources. This will complicate the link between supply and demand. Where demand used to be the only unknown, also a large part of the electricity supply will become less certain. It is necessary to be able to...

Modeling the interplay between storage and flexibility in power systems

The need for a more resource-efficient and low-carbon electricity sector has boosted the integration of Renewable Energy Sources (RES) in power systems, especially of wind and solar energy. However, their intermittent output hinders the match of electricity demand and supply which is required for the smooth operation of the electricity grid....

Modeling a Proton Exchange Membrane Fuel Cell using Non-Equilibrium Thermodynamics: A Second Law analysis of assumptions and parameters

In this work, a model derived from Non-Equilibrium Thermodynamics, for the Proton Exchange Membrane Fuel Cell, was utilized in order to explore the effect of the assumptions and the transport parameters in the consistency of the model; that is, the compliance of the model with the Second Law of Thermodynamics. This thesis begins with a short...

Developing an assessment framework for energy storage technologies at a distribution level in the Netherlands

Electricity production and demand is expected to change significantly due to the transition towards a renewable energy system. Electricity produced from wind and solar energy, and the development of electric vehicles, µ-CHP and heat pumps have strong impact on the distribution grid. To maintain the high level of reliability of the distribution...

Pumped hydropower storage in the Netherlands

Introduction While the world moves towards modern renewable energy sources, these sources are not always available which makes them unreliable. At the same time, problems of balancing the daily peak-demand is still performed with expensive fossil fueled units. Sitting perfectly in between supply and demand is a solution with the potential of...
