Norwegian Companies To Explore Using Aluminium In Floating Offshore Wind Turbines
This is based on this press release from World Wide Wind, which is entitled WORLD WIDE WIND AS and HYDRO ASA Signs Letter Of Intent Aiming At Using Aluminium In Offshore Floating Wind Turbines.
This is the first paragraph.
Hydro, the world leading Norwegian aluminium and energy company and World Wide Wind AS, a Norwegian company developing a floating wind turbine, have signed a Letter of Intent (LoI) to explore the use of aluminium in the renewable wind industry. The two Norwegian companies are partnering up to develop floating wind turbines with a design specifically meant for offshore conditions. The goal is to use sustainable and recyclable materials in the construction, including aluminium.
In Do All Wind Turbines Have To Be Similar?, I said this about the radically different turbines of World Wide Wind.
I’ll let the images on the World Wide Wind web site do the talking.
But who would have thought, that contrarotating wind turbines, set at an angle in the sea would work?
This is so unusual, it might just work very well.
As aluminium is lighter, it might be a factor in the success of the design.
This is the last paragraph of the press release.
World Wide Wind’s integrated floating wind turbines are scalable up to 40MW – 2,5 times current wind turbines – and will use less materials and have a smaller CO2 footprint than conventional turbines. It is World Wide Wind’s ambition that these turbines will represent future design for floating wind turbine design.
40 MW is a very large turbine. This is definitely a case of handsome is as handsome does!
How Liquid Air Could Solve The UK’s Energy Conundrum
The title of this post, is the same as that of this article on The Telegraph.
The article is mainly an article that described the technology and it discloses a few facts.
- The Carrington plant should be delivered in 2024.
- Carrington will be a 30 MW/30 MWh system.
- Efficiency is around 50 %, but there are possibilities to raise it to 70 %.
- Australia is mentioned as a market.
- It is likely to be paired with supercapacitors or a flywheel to have a quick start.
- It seems to me, that turning an idea into a practical system is taking a lot of work and money, and a bit of a rethink.
But hopefully, the system will eventually be developed, as it does promise to be an energy storage system, that doesn’t make high demands on the environment in terms of expensive metals and rare earths.
