In an innovative move within the renewable energy sector, UK-based startup Naked Energy is challenging the conventional approach to solar energy with its unique solar thermal system. Unlike traditional photovoltaic cells that convert sunlight into electrical energy, Naked Energy's system taps directly into the heat of the sun, offering a compelling alternative for heating applications without the need for energy storage.

The solar thermal approach addresses a significant portion of global energy consumption dedicated to heating and cooling, representing 50 percent of the total usage. By capturing the sun's heat directly, the system aims to eliminate the need for complex conversion processes and storage investments, a drawback commonly associated with photovoltaic systems.

At the heart of Naked Energy's innovation is a solar thermal system that utilizes rows of vacuum-sealed glass tubes beneath large glass panels. These tubes absorb solar heat, transferring it to a liquid circulating in a closed loop. The heated liquid is then used to warm water for various applications, including sinks, showers, and space heating, presenting an efficient and sustainable solution.

Naked Energy has recently entered the US market with its first installation at Creighton University in Omaha, Nebraska. The system, which came online this summer, is currently providing hot water for approximately 400 freshmen. With aspirations to displace natural gas heating, the installation has already contributed to a reduction of 40 metric tons of carbon emissions, showcasing the potential of decentralized and modular heating solutions.
