In the relentless pursuit of sustainable energy solutions, concentrating solar power (CSP) has emerged as a formidable contender. CSP harnesses the sun’s energy to generate power, and when coupled with thermal energy storage (TES), it offers a dispatchable energy source that can compete with traditional power generation methods. However, the use of molten salts in TES systems presents a significant challenge: corrosion. This is where the innovative work of Sarah Yasir, a researcher from the University of Derby, comes into play.
Molten salts are an attractive option for TES due to their high heat capacity and stability at elevated temperatures. However, they can be corrosive to the storage tanks and pipework, leading to increased maintenance costs and potential system failures. Traditional methods of mitigating corrosion, such as using specialized alloys or high-purity molten salts, can be costly and may not always provide the desired protection.
Yasir’s research, published in the SolarPACES Conference Proceedings, delves into the world of corrosion-resistant coatings as a potential solution. “The use of anticorrosion coatings is not new,” Yasir explains, “but their application in the context of molten salts for TES is a relatively unexplored area.” Her study provides a comprehensive literature review of corrosion suppression coatings, highlighting the key factors to consider when selecting a coating material.
One of the most promising materials identified in Yasir’s research is nickel-aluminum alloys. These alloys have shown remarkable corrosion resistance in various applications and could potentially revolutionize the way we approach corrosion in TES systems. “The potential of nickel-aluminum alloys as a protective coating is immense,” Yasir states, “and could significantly reduce the construction and operating costs of CSP plants with TES.”
The implications of this research are far-reaching. If successful, these coatings could make CSP with TES a more viable and cost-effective option for large-scale power generation. This could accelerate the transition to renewable energy, reducing our dependence on fossil fuels and mitigating the impacts of climate change.
Moreover, the development of effective corrosion-resistant coatings could have applications beyond the energy sector. Industries that use molten salts, such as chemical processing and metallurgy, could also benefit from these advancements.
As Yasir’s research continues to unfold, it is clear that the future of CSP with TES is bright. The development of effective corrosion-resistant coatings could be the key to unlocking the full potential of this technology, paving the way for a more sustainable energy future. The SolarPACES Conference Proceedings, which translates to the Solar Power and Chemical Energy Systems Conference Proceedings, will be an important venue for sharing these findings with the global scientific community. The energy sector is watching closely, eager to see how this research will shape the future of solar power.
