Chapter 1: Renewable energies

Intermittency in renewable Energy Intermittency is the time scale of natural variation for different renewable energy sources that we can not regulate. Solar radiation – may vary within seconds as well as during day and night, summer and winter Wind – may vary within minutes, seasonal changes Wave – May vary within hours, seasonal changes Tidal – tidal cycle of twice a day Hydro - stock pile energy, seasonal changes 5

Technology for tidal current energy conversion – turbine concepts Vertical axis Horizontal axis Oscillating hydrofoils Horizontal axis Kobold turbine (Italy) Operating since 2001 Power= 25 kW Hammerfest Ström (Norway) Operating since 2003 Power = 300 kW The Stingray (UK), briefly operated during 2003, 150 kW Open Hydro (Scotland) Deployed 2009 1 MW 6
