Freeform heat storage for heating of houses

Due to the earthquakes and climate change, we need to stop using fossil fuels in our energy system, including the burning of natural gas for the heating of housing. Generally, we have the following options: electrical heat pumps, biogas, hydrogen or a heat net using thermal heat or industrial waste heat. The main challenge is to cope with the imbalance in the required heat during the day and in the evening, and the imbalance during the seasons, as the required heat during summer is far less than during winter. These peak moments create a problem in the load of the energy infrastructure when using electrical heatpumps. Therefore, there is a strong need for heat storage. The storage of water as a heat buffer is typically done in cylindrical tanks, which is an inefficient use of space. Especially when these tanks need to be built in existing housing. Day and night buffering is possible, but seasonal buffering costs a lot of space and has to deal with considerable heat loss over time. We think there are more possibilities for storing large amounts of heat. During the project week last February, a preliminary study was done to find out what ways there are to store heat and what possibilities there are to store heat in/near existing houses. This information is the starting point for this project. The goal of this project is to design a system with heat storage for a given scenario and given list of requirements. Based on calculations, you need to convince the stakeholders that this is the best option. This project is part of a student challenge with two other Universities of Applied Sciences, the HAN and HU. The results will be judged by a jury from cooperating companies.

Preparing for a green future – exploiting flexibility on the electrical grid

The energy market is changing. In a strive for a greener economy, the fraction of renewable energy has grown. As a result, power generation has become less predictable, resulting in very dynamic energy prices. For example, prices are very high in the morning and the end of the afternoon, but even negative energy prices are not unheard of these days. Both for electricity suppliers as for consumers, this dynamicity presents an opportunity for cost-savings or even profit. As long as energy consumption allows for a certain flexibility and control over time, demand side load shaping can be used to buy energy for a lower price or to improve the stability of the electricity network. A defining feature of NieuweStroom as energy supplier is that customers do not pay a fixed energy price over their contract, but are billed using the dynamic market prices. This business model makes the use of smart appliances that can adapt their behaviour on the energy prices an interesting proposition for the end users. Furthermore, a significant part of the costs for an energy supplier comes from penalties for a mismatch between generated electricity and what is used on the electricity network. A platform of linked smart appliances that can quickly adapt its behaviour based on the current state of the electricity network could minimize this penalty. Thereby increasing the profit for the energy supplier. This project entails the development of a prototype smart appliance, a platform that can control a large group of these appliances targeting cost savings and network stability, and the necessary user interfaces to interact with the various parts. There are multiple aspects to this assignment, ranging from the practical development of hardware and software,  to the more business oriented parts (e.g. profit models based on control strategies, insight in the trade-off between benefits for the customer and the supplier). Furthermore, research into existing and future standards and protocols is essential to create a solution that provides long term value.

Smart Grid Demokit 2.0

The Dutch government committed itself to the global climate change limitation targets. Besides implementation schemes for increasing the share of renewable energy, the “energy agreement” that the government signed with industry and other organizations contains targets for improving energy efficiency of buildings (houses, offices) and industrial processes. In addition, energy grid management, in the form of Smart Grids, is becoming an ever more important aspect of the energy transition. However, it can be difficult for some to grasp the challenges of Smart Grids, such as balancing energy usage with decentralised energy production. A demokit, in the form of tiles as shown in the figure above, could be used as an instructional tool for people wishing to learn and experiment more with different aspects of a Smart Grid, specifically students at different levels. In addition it could also be used by the clients as a promotional tool, to show examples of projects and research questions that they are involved with. The research group Sustainable Energy Systems at Saxion University of Applied Sciences, in partnership with the research groups Ambient Intelligence at Saxion and Computer Architecture for Embedded Systems (CAES) at the University of Twente, wish to further develop a Smart Grid Demokit, based on the demkit smart grid modelling and control software developed at CAES. Two Saxion Smart Solutions group worked on a preliminary concept and demonstration, in addition to two graduate students. A hardware platform has been chosen. However, a redesign of the physical form of the tiles is required, as well as the edition of serious gaming aspects with which the idea can better be presented by specific groups, specifically  junior school, senior school and college students. There is still much room for creative solutions, as well as testing of the updated system with real students at Saxion and elsewhere. The assignment consists of the following: integration of current demokit hardware into a new tiles design. The tile design should be visually attractive, modular, as well as adhering to the other client requirements, design and implementation of gaming aspects of the demokit, in order to create an interactive educational experience for the different user groups, and showing different energy transition scenarios. Testing a prototype of the game with students. This prototype shoud be a continuation based on the requirements and framework already laid out. Design of the visualisation of the software on the tiles touchscreens.

Quantifying the impact of balancing radiators

The societal need to reduce greenhouse gas emissions with the aim to limit global warming requires us to take all available measures to increase energy efficiency in the building sector. Specifically heating systems in residential buildings, consuming up to 60% of a households energy, show a significant saving potential. It is expected that 20% of a households consumption of natural gas can be eliminated if the radiators (part of the heating system) in residential buildings are adjusted / balanced (water flow) in accordance with the space heating demand. If you chose this project, you get the chance to contribute to a large project of Stichting Pioneering and Saxion ( with the aim to raise the awareness of the citizens of Enschede towards reducing their energy demand. One part of the project is dedicated to the quantification of the gas saving potential by adjusting the radiators in 750 households. Your contribution will be to develop questionnaires to be filled in by the building occupants with the aim to on obtain data about building characteristics and building use; support the organization of data and the analysis of the gas use;  as well as, if interested, to learn about and execute the balancing of radiator for a limited number of households.

Sleep well, muffle better!

Auping bv located at Deventer Netherlands is a big marketplayer world wide in the production of beds. Aupings filosophy is that their production process must be CO2 neutral with minimum impact on the environment. Therefore f.i. they have realized that their products after a full life span will be taken in as a feedstock again for production of new beds. Also their water consumption is reduced to an absolute minimum. To get an idea of it, the total water consumption per month of the auping factory is equal to two households in total! Furthermore the production process of Auping beds is complete Lean. For the goal of auping to be completely CO2 neutral there is one big challenge left to overcome in their production process. In their process route they use a muffle oven to harden the coating for the bed frames and currently this oven is heated with natural gas from Groningen. Auping wants to get rid of this natural gas consumption and wants to explore alternative routes to maintain this muffle process in a sustainable and CO2 neutral way. These routes may be: hydrogen, biogas, upgraded biogas, electrical driven based on solar and/or wind power, but there may also be more routes available these days which could possibly be very interesting. Exploring all these routes and obtaining a businesscase for each of them should be the main output of this 3S study.
