Temporal complementarity of marine renewables with wind and solar generation: Implications for GB system benefits

UK studies on the wider energy system benefits of tidal stream

“…Depth-averaged tidal flow speed data with a duration of 1 month was obtained for each site from regional-scale hydrodynamic models, locally refined to a resolution of circa 50 m within prospective tidal array sites. 2 Harmonic extrapolation was implemented to extend the data sets to 1 year at a 30 minute resolution. The annual flow speed data sets were used to derive the power time series for each farm.…”

“…In this context, Tidal Stream (TS) technologies could be part of the future energy mix, improving its diversity due to the low correlation between the tidal energy profile with PV and the wind profile. 2 Research is emerging that shows the adoption of tidal stream power can enhance supply-demand balancing 3,4 and reduce power variability in the future UK energy mix. 5 TS has predictable daily power output profiles and can be forecasted long-term with high accuracy.…”

Benchmarking a two-way coupled coastal wave-current hydrodynamics model

“…A practical example within the coastal ocean domain relates to marine energy such as at the Orkney-Shetland archipelagos where both wave and tidal sites have already been leased (Johnson et al, 2012). Earlier efforts have demonstrated the simulation and optimisation of tidal energy systems (Jordan et al, 2022;Pennock et al, 2022) in the region, but considering the highly energetic wave conditions the optimisation approaches that embed broader metocean conditions would be invaluable.…”

The energy park of the future: Modelling the combination of wave-, wind- and solar energy in offshore multi-source parks

“…The concept of combining wave- and wind energy was proposed as early as 2010 by [18] and [19] , and in more recent years, the benefits have been explored in various publications. By integrating different offshore renewable energy sources, the park output as a whole can become smoother, as the timing at which each source produces power can be complementary, for both wave-wind [20] , [21] , [22] , [23] and offshore PV-wind [24] , [25] combinations. At the same time, multi-source parks of either wave-wind or PV-wind can increase the extractable energy density of the park reducing the overall space requirements [26] , [27] , [28] , [29] .…”
