Wooden Towers

Wooden towers for all our wind turbine solutions

Innoventum was founded to make renewable energy as sustainable as possible. The idea came to our founder Dr. Sigvald Harryson when he installed his first wind turbine on a sailboat, which resulted in him becoming self-sufficient in electricity. If Sigvald could do this for boats, you should be able to do the same for private individuals and companies. Now the idea of ​​Innoventum was born. But Sigvald also wanted to revolutionize the towers in use and make it available to everyone.

Wooden tower dampens noise and vibration

Our journey started together with the Dali XII which is the tripod tower we use for Dali and the hybrid Dali PowerTower. DALI XII was developed through collaboration with Innoventum and leading universities in wood technology and wood construction in Sweden and France. Then we developed Dalifant, the Giraffe and our Solar Carport.

The advantages of using glulam wood

I början så använde vi oss av solid trä men under de senaste åren har vi valt att använda oss av KL-trä/limträ. Genom att använda oss av limträ får vi många fördelar jämfört många andra byggmaterial:

Through our design, we also have the opportunity to minimize the use of concrete for our foundations compared to other wind turbines, we also have the unique opportunity to install our products on screw foundations, which reduces carbon dioxide emissions (CO2) by 85% compared to concrete. Our wooden towers have been designed for a lifespan of at least 25 years, even in the harshest climatic conditions such as in marine environments and in places where winds are persistently strong. The construction withstands wind gusts of 60 m/s – Class I winds according to international standard IEC 61400-2. These winds are classified as hurricane winds. INNOVENTUM has installed a number of wind turbines in heavily exposed coastal areas that still function flawlessly. Modern forestry is more carbon neutral than naturally growing forests because the trees never complete their natural life cycle which includes decay. In the decay process, all bound carbon dioxide returns to the atmosphere again. In the case of controlled felling of forests, however, the carbon dioxide in the wood product is preserved. INNOVENTUM only uses trees from sustainable forestry. Wood thus has the unique property of being able to do both. By replacing other building materials with wood, carbon dioxide emissions are reduced on average by 1.1 tonnes. Furthermore, 0.9 tons are stored in the wood during a tree’s growth. This means that every cubic meter of wood saves a total of two tonnes of carbon dioxide
