247Solar advances its next-generation solar thermal technology toward commercialisation

247Solar has announced major milestones in the commercialisation of its next-generation solar thermal electric generating technology, which offers commercial/industrial as well as grid-scale customers the chance to harness the sun’s heat for round-the-clock clean power and cut the cost and risks of scaling up renewable energy.

Energy industry veteran Rob Udell has joined as the firm’s CFO to help bring its patented technologies to market, and to conclude an ongoing Series A funding round that generated significant new investment at the end of 2023.

Mr Udell is a well-versed financial and business executive with 20 years of experience as a CFO and 30 years of financial experience. He has led acquisitions, divestitures, and financings worth over $3 billion, working with both public and private entities.

“I’ve worked in the energy business for 15 years and have seen a lot of different types of technology emerge” said Mr Udell. “There’s no question in my mind: 247Solar has a model that is poised to revolutionise the utility-scale and C&I solar sectors, and generate significant value for its customers and investors.”

247Solar’s technology uses mirrors to reflect sunlight onto a receiver tower. That general approach – a version of “concentrating solar power,” or CSP – has been around for quite some time and has produced mixed results in the past. However, 247Solar’s technology addresses previous challenges and provides an easily scalable, economically viable model for the future.

The system is far simpler and more streamlined than traditional CSP designs – improving reliability and reducing potential points of failure. Unlike previous pressurised CSP technologies, 247Solar’s turbines run on air at normal atmospheric pressure, which significantly reduces the system’s complexity.  

247Solar accomplishes that by heating the air to more than 1,800 degrees Fahrenheit (970 degrees Celsius). That’s about 50 percent hotter than conventional CSP systems. That heat can be harnessed for immediate generation of zero-carbon electricity using a unique turbine – or can be captured for later in inexpensive thermal storage.

Importantly, the system doesn’t rely on corrosive molten salts to store heat energy, but rather captures it in abundant, cheaper materials such as sand or iron slag. Later they release their heat to spin the turbines and simultaneously generate electricity and industrial-grade heat when it’s needed.

Traditional CSP power towers needed huge swaths of land and custom engineering. 247Solar’s modular system, however, requires far less land – and all of the parts are built in factories and delivered to the site for rapid assembly. These features slash costs and allow installations to be scaled to any size, in multiples of the basic 400-kW module.
