Vattenfall to work with wooden tower manufacturer

Vattenfall and Modvion claim using wooden towers – instead of steel and concrete ones – could reduce carbon emissions from manufacturing by at least 25%

Vattenfall will work with tower designer Modvion to assess the potential to use wooden towers in future wind farms.

The two companies have also signed a letter of intent to enter into a business development project for evaluating building the technology, commercialising it and supplying the wooden towers for Vattenfall’s onshore wind portfolio.

Vattenfall and Modvion claim using wooden towers – instead of steel and concrete ones – could reduce carbon emissions from manufacturing by at least 25%.

Modvion has previously explained that its wooden towers are “significantly” cheaper than steel ones, and so reduce the levelised cost of energy (LCOE), and can also be transported by road more easily than some modern steel tower segments.

Daniel Gustafsson, Vattenfall's head of land-based wind power development in Sweden, said: “During their life cycles, Vattenfall's wind turbines already have very low levels of climate-impacting emissions. We want to drive those levels down even further.

"We see that wooden towers can be part of our solution for decreasing our carbon dioxide footprint, which can complement the work we are already doing with fossil-free steel as an example.”

Vattenfall is currently developing or building  roughly 5GW of onshore wind farms.

Despite the agreement with Modvion, the Swedish energy firm stated that steel will still be used in many wind turbines, with wooden towers an "important addition".

Modvion installed a protoype unit of its wooden tower at a test site in Sweden earlier this year.
