Hybrid Energy Storage System (HESS) have the potential to offer better flexibility to a grid than any single energy storage solution. However, sizing a HESS is challenging, as the required capacity, power and ramp rates for a given application are difficult to derive. This paper proposes a method for …

Renewable energy sources have an intermittent character that does not necessarily match energy demand. Such imbalances tend to increase system cost as they require mitigation measures and this is undesirable when available resources should be focused on increasing renewable energy supply. Matching supply …

From the start of the energy transition is has been believed that the development of wind power as a renewable source of electricity was vital for reaching the climate goals related to the decarbonization of the energy sector. The LCOE variable is globally applied when comparing the cost for the use …

The Netherlands is aiming for the roll-out of more solar PV. However like many densely populated countries, the country is running into issues of lack of space. Opportunities around infrastructural works like highways provide space without compromising the landscape. Examples of this double use are already …

The Nieuw Statendam is equipped with a program called ENIRAM. This program calculates the optimal engine configuration and load expressed in revolutions per minute of the propellers. The issue with this program is that it only looks at the main power plants and does not take the waste heat recovery system …

Meeting the Paris Climate Agreement goals for renewable energy, sea level rise protection and nature preservation require innovative multifunctional solutions in the Netherlands. As part of the Delta21 project, which looks at creating an energy storing reservoir and an energy producing tidal power plant …

Trends and driving forces around us are moving fast in multiple directions. Technical developments in the fields of circular economy, internet of things, bio-based products, robotics, energy and materials are influencing and reshaping our transactional and contextual environment. To create integrated …

An estimated 17 million tonnes of tires are discarded annually. Re-use is achieved by retreading (9%), recycling (39%), energy recovery (37%) and landfill (5%). A preferred, but complex way of recycling is to make new tires from discarded tire rubber. Vulcanised car tire rubber has to be devulcanized …

The objective of an energy management strategy for fuel cell hybrid propulsion systems is to minimize the fuel needed to provide the required power demand. This minimization is defined as an optimization problem. Methods such as dynamic programming numerically solve this optimization problem. Strategies …

An existing fuel cell hybrid distribution truck, built for demonstration purposes, is used as a case study to investigate the effect of stack (kW) and battery (kW, kWh) sizes on the hydrogen consumption of the vehicle. Three driving cycles, the NEDC for Low Power vehicles, CSC and JE05 cycle, define …
