MIT-originated 247Solar secures funding to advance its concentrated solar power systems combining thermal storage, aiming to revolutionise industrial heat and electricity supply with scalable, zero-emission solutions.
247Solar, an energy technology company originating from MIT, has announced a $25 million Series B funding round aimed at scaling its industrial-grade heat and continuous electricity solutions designed for commercial and industrial sectors. According to the company’s statement, the new capital will accelerate deployment of its technology, which the firm claims can deliver high-temperature process heat alongside round-the-clock clean power, addressing one of the most challenging aspects of industrial decarbonisation.
The funding round has reportedly secured $3.5 million from existing investors and has attracted further commitments under active due diligence. The company’s pipeline, valued at approximately $250 million, spans six continents and includes projects ranging from large utilities to off-grid mining operations. 247Solar said it will use the funding to expand its energy-as-a-service business model, reduce costs through mass production, develop a new industrial thermal battery solution, and engineer a larger 3.5 MW version of its current 400 kW modular system, targeted for deployment in 2027.
247Solar’s technology uses concentrated solar power combined with long-duration thermal energy storage to provide continuous power and industrial heat. The system employs sun-tracking mirrors to heat air up to around 1,000°C at atmospheric pressure, driving turbines for electricity generation and providing thermal energy for industrial processes. Excess heat is stored using ceramic pellets or sand, enabling the system to operate reliably during non-sunlight hours, a feature the company highlights as crucial for industrial users who require uninterrupted energy supply.
Industry observers note that industrial heat accounts for roughly 60% of energy consumption in industrial sectors, mostly generated through fossil fuels. 247Solar’s approach, combining heat and power generation with thermal storage, positions it as a potentially transformative solution that could reduce energy costs by 25% and slash carbon emissions by up to 95%, according to the company.
The company has reached technological milestones backed by a portfolio of over 40 patents worldwide, including a recent patent grant in Australia covering its solar receiver and thermal storage technologies. Australia is highlighted as a strategic market due to its high solar potential and significant fossil-fuel-reliant industrial operations such as off-grid mining.
While 247Solar emphasises the advantages of its integrated approach over photovoltaic solar alone, independent energy analysts highlight that the scalability and cost competitiveness of such concentrated solar power with thermal storage solutions remain under close scrutiny, especially given the accelerating advancements and cost reductions in battery storage technologies and green hydrogen for industrial heat.
The Series B funding round is being advised by MaxEn Capital Advisors, which specialises in energy project finance and development. The firm’s senior managing director stressed the importance of dependable high-temperature heat and clean power for decarbonising heavy industry and expressed optimism about the technology’s market potential.
As the industry looks for ways to transition from fossil fuels without sacrificing reliability or cost-effectiveness, 247Solar’s model of modular, factory-built systems operated under long-term power purchase agreements aims to de-risk investments and promote adoption. The company plans to expand its commercial team to accelerate market entry, particularly targeting sectors including mining, data centres, hydrogen production, and desalination.
In summary, 247Solar seeks to position itself as a key player in closing the clean energy gap for industrial processes that demand continuous high-temperature heat and power. However, the broader industrial decarbonisation landscape remains competitive and dynamic, suggesting the company will face substantive challenges in scaling technology and demonstrating cost competitiveness relative to alternatives like electrification with batteries or electrolytic hydrogen.
This funding announcement arrives amid growing pressure on the industrial sector to reduce carbon emissions, with heat production representing a notable decarbonisation bottleneck due to its reliance on fossil fuels. The deployment of systems capable of delivering dispatchable, zero-emission heat and power in a modular, scalable manner could potentially reshape energy strategies in heavy industry, though much depends on ongoing project executions, cost reductions, and integration with existing infrastructure.

- https://news.mit.edu/2024/247solar-offers-clean-energy-around-the-clock-0430 – MIT spinout 247Solar is developing high-temperature, concentrated solar power systems that use overnight thermal energy storage to provide round-the-clock power and industrial-grade heat. The systems can be used as standalone microgrids for communities or to provide power in remote places like mines and farms. Each 247Solar system uses a field of sun-tracking mirrors called heliostats to reflect sunlight to the top of a central tower. The tower features a proprietary solar receiver that heats air to around 1,000°C at atmospheric pressure. The air is then used to drive 247Solar’s turbines and generate 400 kilowatts of electricity and 600 kilowatts of heat. Some of the hot air is also routed through a long-duration thermal energy storage system, where it heats solid materials that retain the heat. The stored heat is then used to drive the turbines when the sun stops shining. The company’s first deployment will be with a large utility in India, with plans to scale up rapidly with other utilities, corporations, and communities around the globe.
