Course content

• Management and storage of heat, mechanical, and electrical energy.
• Energy market, research, and application aspects (eg. Smart-grid, off-grid, Ragone plot, buffer concepts).
• Thermal energy storage, heat reservoirs, phase transition utilization and chemically bound heat (eg. A district heating network, solar heat).
• Mechanical energy storage: flywheel, pumps, turbines and heat recovery (eg air compression pump power, flywheels of various sizes).
• Electrochemical storage of electrical energy: important battery technologies and hydrogen technologies (incl. Lead-acid batteries, various Li-ion batteries, various technologies for electrolysis of water, different hydrogen storage technologies, and various fuel cells).
