Siemens Gamesa launches a "more ecological" steel tower to advance in wind decarbonization


Siemens Gamesa has announced the launch of its 'GreenerTower', a type of wind turbine tower made of "more ecological" steel, which will allow a reduction in carbon dioxide emissions of at least 63% in steel plates that make up the towers, as reported this Friday by the company in a statement.

In this sense, Siemens Gamesa has established an "exhaustive" certification process to verify that carbon dioxide emissions per ton of steel are limited to a maximum of 0.7 tons in the 'GreenerTower', while maintaining the same properties and quality of steel.

Siemens Gamesa has already signed the first order for a 'GreenerTower' with German utility RWE, agreeing to use 36 such towers at the 1,000 megawatt (MW) Thor offshore wind power project located in Denmark.

The company has detailed that it plans to install a total of 72 SG 14-236 DD offshore wind turbines from 2026, and half of them will have "greener" towers.

Along these lines, the group has indicated that if all the towers installed in a year were 'GreenerTowers', this would be equivalent to removing 466,000 cars from European roads for a year.

Siemens Gamesa has also stressed that the new tower can be used for both onshore and offshore wind turbines for projects to be installed from the year 2024.

As explained by the head of Sustainability at Siemens Gamesa, Maximilian Schnippering, this project is one of the "key" solutions to reach the goal of 600 gigawatts (GW) of new wind power capacity planned in the next five years.

On the other hand, German steelmaker Salzgitter AG is the first green steel supplier to achieve this qualification, which includes third-party certification of carbon dioxide equivalent emissions.

During the standard manufacturing process of each ton of steel, an average of 1.91 tons of CO2 are emitted, but by setting the limit at 0.7 tons of emissions with the new 'GreenerTower', Siemens Gamesa claims to reduce "significantly" the footprint of the component of the wind turbine that generates the most carbon dioxide emissions in its manufacture.
