HOW DOES AN INTERTIDAL WIND FARM DIFFER FROM TRADITIONAL OFFSHORE PROJECTS ?
at 100 metres in height in the top 10 % of windy areas .
In Vietnam , costs for wind and solar dropped below those of coal in 2017 , meaning renewables are now the cheapest form of new power generation on a Levelized Cost of Energy ( LCOE ) basis . While the average LCOE of coal is projected to remain at current levels through 2030 , wind and solar LCOE are set to continue to decline as the technologies mature . We project that wind and solar will be cheaper than hydropower around 2022 .
This would be the same story though in a lot of Vietnam ’ s neighbours . Wind and solar are fast becoming the cheapest forms of new energy in markets throughout the region and across the world . Countries that previously relied on imported fossil fuels , sending money overseas month after month , are now realising that they can tap their own indigenous wind and solar resources to deliver clean , cheap power to consumers without the need to fund fuel shipments .
HOW DOES AN INTERTIDAL WIND FARM DIFFER FROM TRADITIONAL OFFSHORE PROJECTS ?
Intertidal projects are located in the shallow near-shore waters , and use onshore wind technologies to harvest wind resources from the sea . Turbines are built on top of raised foundations , using the same foundation technology as onshore wind farms . The tower , however , is coated in a special paint to prevent corrosion in the marine environment . This technology reduces disruption to farming and other activities on land close to the shore , but does not
