As recently as May last year, Modvion's first wooden tower was erected on Björkö outside Gothenburg.

Now the world's leading wind turbine manufacturer becomes Danish Vestas' partner in the company, with the aim of introducing wooden towers in its product line to reduce its climate footprint.

This means new factories and more employees at Swedish Modvion, which today has a development factory in Gothenburg.

- In this way, we get more Swedish jobs, more renewable delivery from wind power and also show that it is possible to build really demanding dynamic applications of laminated wood, says Otto Lundman, CEO and co-founder of Modvion.

Individual wind turbines have been built in the world in wood in the past, but this construction is planned to be manufactured on a large scale.

The hope is to be able to build hundreds of towers per year in just a few years.

Plywood of spruce

The wood used in the production is a kind of plywood of Swedish spruce, a material that is stronger by weight than steel and will be able to provide cheaper production, according to the company.

According to their calculations, carbon dioxide emissions are reduced by about 30 percent during the construction of a wind turbine with laminated wood towers, compared with a standard steel structure.

Has managed peak load

The tower that was erected on Björkö is part of a test wind turbine operated by the Swedish Wind Power Technology Center at Chalmers University of Technology.

Several research projects are already underway on the construction and what it stands for.

- It has gone as expected, in some cases above expectations.

The greatest load on the tower is when the wind turbine is stationary and there is a storm outside.

So we have already tried the peak loads on the tower and it can handle it without further ado.

The next step is to examine how well the material works in the long run.

One strength of the design is that it is built in modules.

This makes shipping much easier and also opportunities to transport tower parts with a larger diameter than before.

It also creates good conditions for being able to build towers for over 200 meters high wind turbines - perhaps over 300 meters in the long run, according to Modvion's CEO Otto Lundman.
