Energy storage for sustainable buildings and districts

Sustainable energy transition requires integration of major technological changes in renewable energy production, energy storage for resilience and demand-side energy savings.

The buildings sector is responsible for about one-third of global energy use and energy-related CO2 emissions. With the rising deployment of renewables, energy storage plays a critical role for shedding and shifting building loads flexibly and increasing building energy savings, performance and indoor comfort.

This course presents students with a broad understanding of energy storage systems. The course equips students with a systems approach for building energy storage systems to decarbonise the building sector.

Upon completing the course, students will have the knowledge and skills necessary to analyse, design and optimise advanced energy systems, contributing to the development of sustainable energy solutions for future generations.

Course contents

• Overview of energy vector and conversion technologies (overview of energy vectors such as heat, biogas, transportation fuels and hydrogen, alongside the principles and applications of electromechanical, wind and solar energy conversion technologies).
• Energy storage systems (incl. electricity storage and capacitor systems like electrical double-layer capacitors, mechanical storage systems such as pumped hydro, compressed air, and flywheels, as well as geothermal energy storage).
• The course will also cover electrochemical (secondary batteries, flow batteries), chemical (hydrogen) and thermal storage technologies.
• Future energy systems and district heating (Analysis of future energy systems, with a focus on future district heating systems incorporating distributed heat sources. Discussion on the integration of seasonal storage technologies and modeling techniques for smart buildings in local energy communities).
• Multi-objective optimisation for building energy storage and renewables accounting for electricity market.
