- Wind Energy
The growth in the amount of solar and wind energy generated onshore and offshore inevitably has an impact on the environment. This may be a positive influence or bear the risk of being negative. For example, depending on the design, solar parks can contribute to improving biodiversity while wind turbines may pose a risk to birds.
In addition to technological challenges, there are many research topics related to environmental impact. TNO has selected four such topics for which it is investing in a new research infrastructure.
Our experts in the field of solar and wind energy work closely with knowledge institutions such as Wageningen University & Research (WUR) and Deltares. Other partners are developers, builders and operators of solar and wind farms, energy companies and NGOs.
TNO has been doing research with partners in this area, to broaden and deepen it. Existing facilities, including mobile installations for wind measurements, are being expanded with financial support from the Ministry of Economic Affairs and Climate Policy. TNO, together with Hogeschool Zeeland, is doing research into the effects of floating solar parks on life under water and biodiversity in the Fieldlab Green Economy Westvoorne on Lake Oostvoorne. In the respect of wind energy, TNO has been participating in various international projects on the detection of bird strikes for some time now.
TNO has a 3D bird radar, a WT Bird system to detect collisions with wind turbines and a laser-based metering system to measure wind speeds. Together with our partners, we map the behaviour of birds around wind farms and investigate the influence of wind turbines on this. In this way, detailed research data on bird movements in relation to wind energy will be added to the existing knowledge. This new knowledge will be particularly important now with respect to European ambitions of an enormous increase in the amount of wind generated offshore.
TNO has new facilities to investigate the influence of solar parks on land and inland water. This involves monitoring soil quality including nutrients and humidity, solar irradiation below and above water, water life and water quality including oxygen, nutrients and algae. The wind energy metering instruments can also be used to study the behaviour of birds around solar parks, both on land and inland waters.
In addition to the mostly mobile facilities mentioned in the foregoing, a new lab has been set up to investigate the (fire) safety of solar energy systems and solar parks, as well as important issues regarding circularity and recycling.
The TNO research facilities and programmes are unique in the world. Never before have studies into the effects of the solar and wind energy been combined and the expertise of different knowledge institutions clustered in this way. This enables the Netherlands to build up a unique leading position. Both government and industry need new insights into solar and wind energy in which technology, ecology and safety go hand in hand. New knowledge helps Dutch companies to lead the way in ecologically responsible design, construction and operation of wind and solar parks.
