When it comes to concentrated solar power (CSP), most people immediately think of the scorching hot deserts of North Africa or the American Southwest. And it’s true, these regions have been at the forefront of CSP development, with their abundant sunlight and spacious land areas making them ideal for massive solar farms. But what if I told you that CSP has the potential to thrive in a completely different environment: the coast?

Yes, you read that right. While CSP is often associated with the sun-baked deserts of the world, its applications are far more versatile than we give it credit for. And I’d argue that coastal regions, with their unique set of challenges and opportunities, are actually a perfect fit for CSP technology.
Let’s start with the obvious advantages. Coastal regions are often located near population centers, which means that energy generated from CSP plants can be easily transmitted to the areas where it’s needed most. This reduces transmission losses and makes the entire system more efficient. Plus, the ocean breeze and sea air can actually help mitigate the cooling issues that sometimes plague CSP plants in desert environments.

But the real game-changer is the ability of CSP to provide dispatchable power – in other words, energy that can be turned on and off as needed. This is crucial for coastal regions, which often experience variable energy demand due to the presence of ports, airports, and other industrial facilities. By providing a reliable source of power, CSP plants can help stabilize the grid and reduce our reliance on fossil fuels.
Of course, there are also some unique challenges to consider when building CSP plants in coastal environments. For one thing, the salt-laden air can be corrosive to the mirrors and other equipment, which means that specialized materials and maintenance procedures are required. And then there’s the issue of water availability – while the ocean is a rich source of water, the process of converting seawater to freshwater for use in CSP plants is still in its infancy.
Despite these challenges, I believe that CSP is poised to revolutionize the way we think about energy production in coastal regions. Companies like Siemens and Abengoa are already developing CSP technologies specifically designed for coastal applications, and some promising pilot projects are underway in countries like Portugal and Chile.
So the next time you hear someone say that CSP is only for the desert, correct them. Concentrated solar power is a versatile technology that can thrive in a wide range of environments – including the coast. With its ability to provide dispatchable power, reduce our reliance on fossil fuels, and help stabilize the grid, CSP is an exciting solution to some of the world’s most pressing energy challenges.
