**[Ilika plc](https://www.directorstalkinterviews.com/company/ilika-plc/ika.l)**(
[LON: IKA](https://www.directorstalkinterviews.com/company/ilika-plc/ika.l)), a 
pioneer in solid-state battery technology, announced today it has successfully integrated
its Stereax® solid-state battery in condition monitoring sensors placed on a test
wind turbine blade at the Offshore Renewable Energy (ORE) Catapult facility in Blyth,
UK. The trial, carried out in January 2020, concluded that energy harvested from
the vibrations of the blade can charge a Stereax® M250 solid-state battery which
can in turn power condition monitoring sensors and LoRa communication.

The global wind turbine market consists of over 300,000 wind turbines providing 
600 GWh of renewable energy per annum. This is forecast to increase by 22.5% from
2018 to 2025 with annual market revenue generation rising to $30.5bn. The repair
of turbine blades is very costly due to the difficulty of accessing the blades themselves:
an average blade repair can cost up to $30,000 and a new blade costs, on average,
about $200,000. Real-time monitoring of the blade’s health can help to avoid catastrophic
events caused by delamination, cracks, impact or ice.

As part of the Innovate UK-funded development program “SmartBlade”, in collaboration
with Titan Wind Energy, Ilika partnered with the Universities of Chester and Aston
to design and construct an autonomous (i.e. self-powered) wireless sensor device
which uses harvested energy from the vibration of the blade to increase battery 
life. The device has now been successfully tested in a real-life environment, i.
e. a specially constructed test blade, of length 40m, placed in ORE Catapult’s facility.
The tests confirmed the durability of the sensors in such hostile environments and
yielded numerous useful data such as the best section of the blade to collect optimal
wind-induced energy. Moreover, the test confirmed theoretical models showing that
enough energy can be harvested from wind to charge a Stereax M250 sufficiently to
enable full sensing and data transmission cycles every 10 minutes. Such a short 
interval is more than sufficient to provide real-time condition monitoring information
of possible issues such as crack formation or component failure, enabling them to
be fixed before incurring costly downtime and repair costs.
