Is there any point in combining solar and wind generation on the same offshore platform?
Belgian researchers have analysed the complementarity at sea between a wind platform and a solar structure. They found that in some cases the combination would increase the yield of renewable electricity by 47% while occupying only a limited surface area.
They noted that complementarity increases over longer periods of time
in a context of major global warming. "On the basis of 10 minutes, an hour or 3 hours, only a small degree of complementarity is apparent. Complementarity is greater for daily, weekly and monthly lead times. It increases with the length of the deadlines", says the study. It adds that "the behaviour of solar and wind resources in the Belgian North Sea makes it a prime location for hybrid solar-wind offshore projects, as strong periods of solar energy alternate well with strong periods of wind energy. "
"A 3 GW photovoltaic system coupled with a 2.3 GW wind system in the Belgian North Sea would increase the yield of renewable electricity by 47% while losing only 16% of the photovoltaic electricity due to the reduction for the assumed connections".
