Located in Ottawa, Ontario, BluWave-ai applies real-time optimization to direct energy precisely when and where it’s needed most—minimizing waste.
#2: COFOVO Energy
COFOVO Energy has developed an advanced, ultra-efficient solar panel that delivers up to twice the energy output versus standard models. Spun out of uOttawa’s SUNLAB, this breakthrough technology helps accelerate the shift to clean energy by making solar more powerful, space-efficient, and cost-effective.
#3: Ginkgo Sustainability
Ginkgo Sustainability Inc is reshaping skylines—one rooftop at a time. As Canada’s largest green roof installer, this Toronto-based SME has transformed 3.2 million+ square feet of unused rooftop space into vibrant, energy-efficient ecosystems. The result? Lower emissions, cooler buildings, and a greener urban landscape.
#4: Evercloak
Cool smarter, not harder with Evercloak Inc.
Located in Kitchener, Ontario, Evercloak’s advanced membrane technology saves energy, cuts emissions, and improves air quality indoors.
By separating dehumidification from air conditioning, their system can reduce HVAC energy use by up to 50%—a true game-changer in humidity control.
#5: AlumaPower
What if clean energy came from scrap metal?
Operating out of Sarnia, Ontario, AlumaPower turns 100% recycled aluminum into zero-emission power—no mining or pollution, just breakthrough innovation for a greener, more circular future.
Producing four times the energy density compared to lithium-ion batteries, this alternative fuel source is ideal for long-duration, untethered energy applications.
#6: GreenLIB
Dead EV batteries aren’t waste... they’re a goldmine.
Just ask GreenLIB , a Kingston-based SME whose patented technology extracts and refines up to 95% of critical minerals from end-of-life batteries—producing high-purity outputs such as lithium, graphite, and Ni/Co that are ready for reuse in the battery supply chain.
GreenLIB’s recycling technology also reduces CO₂ emissions by up to 82% compared to primary mining, making it not only a sustainable alternative to raw material extraction but a key player in the circular economy.
#7: Hydrostor
Energy storage just got a serious upgrade with Hydrostor .
Based in Toronto, Hydrostor’s Advanced Compressed Air Energy Storage (A-CAES) technology delivers long-duration energy storage that’s sustainable, cost-effective, and accelerating the clean energy transition.
#8: Prosperity Group
Posterity Group is a consulting firm in Ottawa that helps clients identify strategic opportunities to reduce energy use while managing risks tied to climate change and emerging technologies.
#9: CHAR Technologies
CHAR is where circular economy meets scalable cleantech.
A Toronto-based SME, CHAR Technologies Ltd. specializes in converting organic materials into clean energy outputs such as renewable natural gas (RNG), green hydrogen, and biocarbon.
