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
- We have the opportunity to use a sustainable building materia
- Glulam also gives us the advantage that we have stored carbon dioxide (CO2) in our products, which leads to our products becoming climate positive more quickly
- Glulam is one of the strongest building materials relative to its weight.
- It is a very beautiful material that blends in and ages with dignity
- Glulam is one of the building materials that copes best with extreme environments, which means that we can install it in all environments.
- To install our constructions in wood, no special tools are needed, which means that anyone can do an installation.
- When it comes to wind turbines, the wooden constructions give us sound absorption and reduce vibrations.
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

* – 1m3 of wood replacing steel offsets 1500 kg of CO2 (incl. transportation and processing of wood)
** – 582 kg CO2 is emitted per ton of steel manufactured. Density of steel: 7850 kg/m3
