Australia is “ripe” for innovation in floating offshore wind farms, and could use its deep ports, offshore know-how and excellent wind conditions to become a “first mover” country for the new technology, according to a new study.
Oceanex commissioned the report from consultants MBB Group to look into the supply needs for its plans to build at least two multi-gigawatt offshore wind projects using floating foundations, and tapping into demand from green hydrogen and the retirement of coal generators.
Oceanex is initially targeting projects off the coast of the Hunter and Illawarra coal regions, with two different 2GW projects, and the possibility of two others either closer to Sydney or further south near Eden.
There is growing interest in offshore wind, with at least 12 different projects identified by different developers across Australia, and the market operator also outlining the potential of up to 40GW of capacity in four different offshore zones.
Offshore wind is being promoted because of the scale of the projects can replace some of the coal capacity expected to retire over the next 10 to 15 years, and because it can tap into the existing infrastructure.
Costs have traditionally been high, but they are falling rapidly, thanks to the sheer scale of the projects and the size of the turbines that can be located offshore. A recent auction in German resulted in winning tenders from offshore wind projects that required no subsidy - link - Giles Parkinson - link - more like this - link
