Blue-Green Energy

Blue-Green Energy (Offshore Renewable Energy)

Blue-green energy refers to renewable energy from the sea. The UK has agreed to reduce by 80% the amount of carbon being released in to the atmosphere by 2050. Marine renewable energy can make a significant contribution to meeting our future renewable energy and carbon reduction targets. Research shows that 15-20% of the UK’s electricity demand could be met by wave and tidal energy by the year 2020. The seas around the UK have the potential to provide a large amount of renewable energy from tides, waves and offshore wind.

Marine energy also includes unconventional sources like marine algal biomass, offshore solar, thermal energy from the temperature differences between surface and deep water, and osmotic power generation which exploits the energy available from differences in the salt concentration in seawater.

LISCO partners collaborate more widely with the Centre for Offshore Renewable Energy Research, which includes the University of Liverpool, NOC, and connects to others experts at the University of Southampton and the Ocean University of China. We also have strong links to the Liverpool University Stephenson Institute for Renewable Energy.

Disciplines involved in this research include marine science, engineering and environmental science and it has overlaps with all the other LISCO themes i.e. Coastal Resilience, Oceans and Climate, Ports and Maritime, The Bio-Economy and The Sea and Society.

Key research questions include:

  • What are the likely environmental impacts of offshore renewable energy projects?
  • How can offshore renewable energy counteract the effects of a changing climate?
  • How can we address the socio-economics of large-scale tidal power to make it economically and environmentally acceptable?
