DAY 1: KIVI ENERGY SYMPOSIUM – 24 September 2015

The 2015 KIVI Energy Symposium will be on the topic of compact conversion and storage of energy: Blue Energy. The purpose of this symposium is to provide a broad perspective on the potential of energy storage and to build a bridge between enterprises and universities.

This is a combined symposium of the KIVI departments Applied Physics and Mechanics and the Strategic Area Energy of TU/e.

Also a guided tour at the Darcy lab is available for only a limited amount of people.This lab is the new magnet laboratory of the TU/e. Signing up for the guided tour is only possible by mailing to Dieudonnee Cobben.

  • Welcome by David Smeulders, chair of the day – TU/e
  • The challenge to develop technology that is able to harvest Blue Energy in a clean, efficient and cost-effective way by Bert Hamelers – WETSUS  
  • The scientific developments and design strategies for Blue Energy in relation to the practical application by Kitty Nijmeijer – University Twente
  • The Microbial Fuel Cell, a clean, CO2 neutral, and efficient technology to recover electricity from wastewater by Annemiek ter Heijne – Wageningen UR

Our Western lifestyle requires a lot of energy. Next to make our energy supply system more sustainable by using energy from the sun, wind and water, we also should look critically at our consumption patterns. However, in the last few decades efforts to change our behavior have not been very successful yet. Why this is so difficult, what we have learned and what we can do about it, is the theme of this EnergyDays. The invited speakers addressed this from different perspectives.

  • Welcome by Geert Verbong, TU/e
  • The psychology of saving energy by Ellen van der Werff – University of Groningen
  • Engaging with transitions in organized behaviours: the example of smart grids by Gert Spaargaren – Wageningen UR
  • Behavioural change from theory to practice by Ruth Mourik – Duneworks

The availability and efficient (re)use of material resources is key to make the transition to a sustainable society. We will have to move from linear use of materials to a circular economy. In this EnergyDays, the material challenge will be approached from different directions. We will address the impact of scarcity in material resources and the need to innovate our technologies. We will focus on the demanding material requirements for future fusion reactors and the need for basic research on novel materials and concepts. Also we will take a look to research on clever product design to improve primary material use, resource efficiency and recycling possibilities.

DAY 4: ENERGY NOW – 9 June 2016

Energy Storage & Smart Grids – This congress was mainly organized by Team Energy!

Energy Now is a congress directly related to the current energy transition. Our goal is to inspire, interest, and trigger students to take elegant action in the transition towards sustainable energy.

DAY 5: METAL FUELS – 27 October 2016

The EnergyDays on Metal Fuels were a great success. Barely enough seats to host the many people that were attracted by the topic. We have learned that metals are a very promising clean energy carrier that may replace a large part of the fossil fuels we are using today. The high energy density of metal fuels was demonstrated by Yuriy Shoshyn who combusted some metal powder during the event leading to a very big flash.

Imagine you live in 2030 and you want to travel a few hundred kilometers with your new iron-fueled car that does not emit any CO2. You insert a new cartridge with a few liters of porous micron-sized iron powder. You drive the car and when driving, the iron powder is dispersed in air and the powder is burned in a hot turbulent flame transferring the iron powder into micron-sized rust-powder. Inside the iron-car the hot burnt gases are used fire a Stirling engine to drive the car. The burnt rust particles are stored in a separate compartment of the original cartridge and when returning home you bring the (heavier) cartridge back to the store, from where it is shipped to a central place where the rust is transferred back to micro-sized iron particles again using solar energy.

Whether this vision of the future is real, will become clear in the upcoming EnergyDays event where we will explore the possibilities of Metal Fuels as a novel type of energy carrier.

DAY 7: GEOTHERMAL ENERGY – 23 March 2017

Geothermal energy is available 24/7 and can thus potentially complement the intermittent renewables solar and wind energy that come with strong diurnal and seasonal variations. This EnergyDay will focus on the future potential contribution and role of geothermal energy in the Netherlands and abroad, and discuss the technical challenges that we need to address to tap into this underground heat source.

  • Geothermal for Electricity Production: dreams & realities by Brice Lecampion – EPFL, Geo-Energy Lab – Gaznat Chair on Geo-Energy              
  • Heat transition within the Netherlands by Lydia Dijkshoorn –
  • Heat from under our feet – Geothermal energy in the Netherlands by Martijn van Aarssen – IF Technology    

Modern power electronic converters allow to provide electrical energy processing in a very efficient way in many applications including solar and wind energy conversion, hybrid and electric cars, high-performance computer power supplies, switching audio amplifiers, solid-state lighting, utility control and smart grids, portable power, and many others. The goal of the energy days is to present and discuss the state-of-the-art concepts for switching power conversion (developed at the Technical University of Eindhoven), including various topologies for many applications, their operation and control choices, harmonics and filtering, circuit models of real sources and devices, magnetics design, and passive and active component behavior.
