Abstract
While the energy demand is increasing, the world’s natural supply of water and fossil fuels, such
as oil, gas and coal are running low. This is all because of factors such as industrialization,
exhaustive farming practices and a growing population that is estimated to double in the future.
As the need for water continues, the world struggles to respond because even though the
oceans contain about 97 % of the earth’s water, this water is too salty and cannot be used
without proper desalination.
A possible solution for the scare water supply could be the use of reverse osmosis. This
membrane process uses pressure on solutions with concentrations of salt to force water to
move through a semi-permeable membrane, leaving the salts behind. The mayor energy
required for desalination is the one used to pressurize the feed water. And this energy supply
normally derives from the grid. Since renewable energy sources like wind energy, supply a
clean energy source and can help to reduce the dependency on fossil fuel, the idea of this
master thesis is to study the technical and economical feasibility of a seawater desalination
plant powered by offshore wind energy.
Theoretical knowledge of seawater reverse osmosis as well as wind energy is put together into
one unit, and a technical and economical feasibility study of its product is determined. Two
companies, ENERCON and SYNWATER, are used as reference for this master thesis. Even
though both companies have their wind turbines installed onshore, the purpose of this master
thesis is to evaluate if a seawater reverse osmosis plant of a capacity of about 1 hm3 “potable”
water a year can be powered directly by offshore wind energy, as an autonomous system
without extracting electricity from the grid.
