Welcome to our weekly environmental newsletter, where we showcase trends and solutions driving us towards a more sustainable future.
Greetings, this is Emily. I have been intrigued by the concept of floating solar power and have been disappointed by its absence in Canada. Therefore, I was thrilled to learn about the innovative ice-resistant floating solar design developed by Canadian researchers.
This week’s highlights include:
– Canadians develop innovative floating solar solution for icy lakes
– The Big Picture: Overflowing bike parking lots
– Exploring the possibility of cities recycling heat generated by data centers
Solar panels that float on water bodies like lakes and reservoirs are gaining popularity globally, from Japan to France to Paraguay. These “floatovoltaics” can produce clean energy without utilizing valuable land space.
Although floating solar panels have been tested in Canada, their adoption remains limited, mainly due to challenges posed by harsh winter conditions. Koami Soulemane Hayibo, a postdoctoral researcher at Western University, emphasized that the primary challenge in Canada is preventing ice formation during winters.
Hayibo and his team designed a floating solar system to combat ice formation, successfully testing it in a pond in Ontario. By using inexpensive plastic foam instead of traditional metal racks for support, the system overcame cost challenges. The addition of bubblers below the panels prevented ice buildup, ensuring continuous electricity generation.
Despite the additional energy required to run the bubblers, the overall electricity generation cost was estimated at around three cents per kilowatt-hour, comparable to other solar installations in Canada. The researchers are further refining the system to improve efficiency and address any environmental concerns such as microplastic shedding.
The technology holds promise for scaling up and can be applied in various settings, including repurposed mines, hydro facilities, reservoirs, or ponds facing water loss concerns. It could also find applications in smaller settings like backyard pools or unused ponds.
Ibrahim Dincer, a professor at Ontario Tech University, commended the innovation, highlighting its potential applications, such as powering ferries or providing electricity to remote communities. Companies specializing in floating solar solutions already offer alternatives for cold climates, indicating a growing interest in sustainable energy solutions worldwide.
The success of this new floating solar design will depend on its commercial viability and scalability, as experts continue to explore innovative approaches to harness renewable energy sources effectively.
