Thor Offshore Wind Farm To Feature Siemens Gamesa’s Newly Launched GreenerTowers
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Siemens Gamesa has revealed its GreenerTower, a wind turbine tower made of more sustainable steel. The company already closed its first order with RWE to feature 36 of the GreenerTower units at the 1 GW Thor offshore wind project in Denmark.
This is the first paragraph.
Today, tower production accounts for more than one-third of all wind-turbine-related CO2 emissions, according to Siemens Gamesa.
Siemens Gamesa’s new GreenerTower will ensure a CO2 reduction of at least 63 per cent in the tower steel plates compared to conventional steel.
Siemens Gamesa also claim this.
If all towers installed by the company in one year were exchanged with GreenerTowers, it would be the same as removing more than 466,000 cars from the roads in Europe for a year.
The first supplier to be qualified is Salzgitter AG.
- I wrote about Salzgitter’s green steelmaking in WindH2 Hydrogen Project Commissioned In Germany.
- Only a maximum of 0.7 tonnes of CO2-equivalent emissions are permitted per tonne of steel while maintaining the same steel properties and quality.
- Salzgitter’s electric furnaces will be fed with green electricity produced by renewable energy sources.
- Salzgitter AG have recently signed a Power Purchase Agreement (PPA) with Iberdrola.
- It looks like Salzgitter AG are going both the electric and hydrogen route to green steel.
I suspect over the next few years, we’ll be seeing more steel products made with green steel.
In this case, I suspect that Siemens Gamesa could use the same production process with very little modification, which is a great advantage.
WindH2 Hydrogen Project Commissioned In Germany
The title of this post, is the same as that as this article on Chemical Engineering.
This is the introductory paragraph.
Salzgitter AG, Avacon and Linde have taken an important step on the path to decarbonizing the steel industry. With the commissioning of “Wind Hydrogen Salzgitter – WindH2”, Germany’s only cross-sector project, green hydrogen will be produced in future with electricity generated by wind power on the site of the steelworks in Salzgitter.
This sentence describes the hydrogen production.
Avacon, a member of the E.ON Group, operates seven newly built wind turbines with an output totaling 30 megawatts on the premises of Salzgitter AG. Salzgitter Flachstahl GmbH has installed two Siemens 1.25 megawatt PEM electrolyzer units on its plant site that are capable of producing around 450 m3 per hour of ultra pure hydrogen.
It appears that Salzgitter AG are initially using hydrogen to cut their carbon footprint.
To get an impression of the size of the steelworks, look at this Google Map.
Note that if you click on the map to show it in a large scale, stahl is German for steel.
The article is certainly worth a read.
