This capacity requirement is dwarfed, however, by the electricity demand of other sectrors. In other words, 14 GW of offshore wind capacity to serve the Danish electricity market. We arrive at 14 GW installed capacity, to get 7 GW average, to get a little over 5 GW serving Denmark’s demand.The 2 GW extra capacity is needed to accommodate the loss associated with electric energy storage, which we need for when the wind is not blowing.14 GW of offshore wind with a capacity factor of 50% leaves 7 GW gross average power, 2 GW more than Denmark’s average power load.In order to appreciate just how much more electric energy capacity is needed to meet the future need for PtX fuels, we can use Denmark as an example.

Sectors like transport and industry can only partly convert to electric power and will need Power-to-X fuels from renewables. The world is going to need much more green powerĪ full transition to green energy will require the supply of a lot more electricity than today’s global demand. There is just not sufficient shallow-water area available.įor countries lacking the space for solar PV and not having large, shallow water areas for conventional, bottom-fixed offshore wind, floating offshore wind will often be the ideal means for the green transition. Freed from the geographical constraints of shallow water site availability, floating wind opens new paths towards a cost-effective green energy transition in many regions.Īpart from the North Sea and shallow water coastlines off China and the Eastern USA, most of the world’s population centers cannot be served by conventional bottom-fixed offshore wind. All safety precautions have to be done to protect the nearby structures from any damage.Floating foundations enable offshore wind power to serve important new markets. Execution of these foundations requires highly skilled professionals and micro-level supervision supported by an experienced and skilled workforce. Concrete bands are provided at the bottom level to control heave formation.īalancing raft foundations are adopted for high rise buildings with multiple basements. Installation of friction piles or micro piles on partially completed excavation surfaces can also control heave formation to an extent. Heave formation can be minimised by further lowering the water table to a depth below the founding level of the structure. Heaves formations cannot be avoided in any case but have to be controlled or else it may initiate foundation settlements. Heave formation can always happen while doing deep excavations because of the weight of soil on both sides of the excavation pit. Heave formation in Floating Raft Foundation
