When it comes to renewable energy, solar power stands out as a beacon of innovation and efficiency. Enter Solaxer, a Swiss clean-tech company, pushing the boundaries with their innovative solar thermal tubes. By achieving an astounding 96% solar absorption rate, they are set to revolutionize industrial heating processes.
The Genesis of Solaxer
Founded in 2021, Solaxer emerged from the research-driven environment of the Swiss Federal Institute of Technology in Lausanne (EPFL). The company’s co-founders, Dr. Anna Krammer and Maxime Lagier, brought their extensive experience in selective solar absorber coatings to the table, culminating in the creation of their patented solar thermal tubes.
Why Industrial Solar Heating Matters
Did you know that about 75% of industrial energy consumption is used for heating processes? Shockingly, 90% of this heat is sourced from fossil fuels like coal and oil, contributing significantly to global CO2 emissions. Industrial solar heat, or Solar Heat for Industrial Processes (SHIP), offers a promising alternative, providing solar steam and process heat with high conversion efficiency.
SHIP’s potential is immense, having already seen a 70% cost reduction over the past six years. It’s projected to grow annually by 92% until 2030, marking it as a critical player in the renewable energy sector.
The Innovation Behind Solaxer’s Solar Thermal Tubes
The heart of Solaxer’s innovation lies in their solar thermal tubes, coated with a unique black spinel material. This patented coating ensures high optical performance and durability, even at temperatures soaring up to 400°C. Unlike conventional coatings that degrade under high heat, Solaxer’s solution remains robust and efficient, slashing maintenance costs and enhancing longevity.
Key Features:
- High Solar Absorption: The black spinel coating achieves a remarkable 96% solar absorption rate.
- Low Thermal Emittance: With just 12% thermal emittance, the tubes efficiently convert and retain solar energy.
- Durability: Resistant to oxidation and degradation, ensuring long-term performance even at extreme temperatures.
Eco-Friendly and Cost-Effective
Solaxer’s approach isn’t just about performance; it’s about sustainability too. The coating process uses minimal, harmless chemicals, significantly reducing environmental impact. Additionally, the technology is cost-effective, utilizing low-cost manufacturing processes to boost efficiency and affordability.
Patent Technology:
- Localized Induction Heating Absorption: The coating is transparent at room temperature but turns black when heated, maximizing solar energy absorption.
- Energy Efficiency: Each meter of the coated tube consumes just 0.033 kWh, making it highly energy-efficient.
Expanding Horizons
Solaxer’s first prototype, capable of producing two-meter-long tubes, set the stage for further advancements. By early 2023, they rolled out a second prototype, extending production capacity to three meters. This leap enables an annual production of 5000 meters of solar thermal tubes.
With numerous letters of intent and projections to cover over 800,000 square meters of solar collectors in the next five years, Solaxer is poised for significant impact. Their technology promises to save 300,000 cubic meters of natural gas or 250,000 liters of oil per megawatt-peak (MWp) solar field annually.
Recognition and Future Prospects
In 2022, Solaxer’s innovative strides earned them a spot in the Gebert Rüf Foundation’s innovation acceleration program, along with a grant of 150,000 Swiss Francs. This funding is pivotal in scaling up production and completing their first pilot installations, paving the way for Solaxer to become the go-to supplier for solar thermal collectors.
Conclusion
Solaxer’s innovative solar thermal tubes stand as a testament to what can be achieved when cutting-edge research meets practical application. With a focus on high efficiency, durability, and eco-friendliness, Solaxer is not just improving solar technology but is also playing a vital role in the global shift towards sustainable industrial heating. As they continue to expand and innovate, the future of industrial solar heating looks brighter than ever.
