What 247Solar does
247Solar, Inc. is a US-based clean energy company that designs, builds, owns, and operates modular high-temperature concentrated solar power (CSP) plants with overnight thermal storage, delivered to commercial and industrial customers through long-term Power Purchase Agreements. The company's technology platform, originated at MIT, captures solar energy at 970°C using proprietary solar collectors and stores the heat in ceramic pellets for 18+ hours, allowing round-the-clock electricity and high-temperature industrial heat generation without batteries or molten salts. Stored heat is reconverted to electricity via the proprietary Heat2Power turbine, which operates at atmospheric pressure and can also burn hydrogen or other fuels to ensure 24/7/365 dispatchability.
The company sells turnkey energy under an Energy-as-a-Service model where it assumes all capital, operations, maintenance, insurance, and repair responsibility, while customers pay only for the energy consumed at fixed, predictable rates with no upfront investment. Its primary segments are off-grid mining (replacing $150–200/MWh diesel generation), industrial heat and power applications such as cement, glass, steel, and minerals processing requiring heat up to 1000°C, microgrids, data centers, green hydrogen production, and economic development zones. Development partners include US DOE, Fraunhofer, Saint-Gobain, Oak Ridge National Laboratory, DLR, Brayton Energy, WorleyParsons, and Capstone, and the company maintains an active project pipeline of $250 million spanning six continents.
Founded around 2014–2015 and headquartered in Great Falls, Virginia, 247Solar remains a venture-backed private company with 1–10 employees and a recently launched $25 million Series B funding round (December 2025, $3.5M secured from existing investors, advised by MaxEn Capital Advisors). Through 2025 it materially expanded its executive bench with a CFO, CIO, CPO, and CCO, and added dedicated business development coverage in Zimbabwe and South Africa to pursue the Africa mining market.

247Solar product offering
Product offeringCore offering
247Solar designs, builds, owns, and operates modular ultra-high-temperature concentrated solar power (CSP) plants that capture solar energy at 970°C and store it in simple ceramic pellets for 18–20 hours, converting the heat back to electricity via a proprietary Heat2Power turbine. The integrated 247Solar Plant, HeatStore thermal storage, and Heat2Power turbine deliver round-the-clock clean electricity and industrial-grade process heat to commercial and industrial customers under long-term Power Purchase Agreements with no upfront capital required.
Product overview
247Solar offers a modular Ultra-High-Temperature Solar Technology Platform comprising three core products: the 247Solar Plant™ for concentrated solar power generation, the HeatStore™ for long-duration thermal storage in ceramic pellets, and the Heat2Power™ Turbine for converting stored heat to electricity. These components work together to provide round-the-clock clean heat and power without batteries or molten salts. The company delivers these solutions primarily through an Energy as a Service (PPA) model where they design, build, own, and operate systems at customer sites. The technology captures solar energy at 970°C—higher than conventional CSP—stores it in ceramic pellets for up to 18+ hours, and converts it back to electricity via a proprietary turbine. Applications span mining, industrial heat and power, microgrids, green hydrogen, and grid-scale baseload power.

Products and services
- 247Solar Plant™ Next-generation modular concentrated solar power (CSP) plant that captures solar energy at 970°C (1800°F) and stores it in ceramic pellets, enabling continuous 24/7 clean electricity and industrial-grade heat generation without batteries or molten salts. Sold to commercial and industrial customers (mining, heavy industry, data centers, green hydrogen, microgrids, economic development zones) under Power Purchase Agreements.
- HeatStore™ Long-duration thermal energy storage product that converts excess power from PV, wind, or the grid into ultra-high-temperature heat stored in simple ceramic pellets for up to 20 hours, enabling round-the-clock dispatchable power generation from intermittent renewable sources. Designed for integration with the 247Solar Plant and as standalone thermal storage for industrial and microgrid customers.
- Heat2Power™ Turbine Proprietary atmospheric-pressure turbine that converts stored thermal energy from the HeatStore system into electricity without combustion or emissions, by circulating air through the heat storage medium. Can also burn various fuels including hydrogen to ensure 24/7/365 dispatchability. Forms the power-conversion stage of the integrated 247Solar Plant platform.
- Energy as a Service (Power Purchase Agreement) Build-own-operate Power Purchase Agreement (PPA) service in which 247Solar designs, builds, owns, and operates its modular CSP systems at the customer's site, delivering clean electricity and industrial heat at a fixed, predictable rate with no upfront capital investment from the customer. Includes all operations, maintenance, insurance, and repair responsibilities. Targeted at commercial and industrial customers in mining, industrial heat and power, data centers, green hydrogen, microgrids, and economic development zones.

247Solar competitors and assessment
Company assessmentEmerging players
- Synhelion: Synhelion develops concentrated solar thermal systems to produce solar fuels and industrial heat at high temperatures. It overlaps with 247Solar in ultra-high-temperature solar thermal capture and industrial-decarbonization applications, though its primary market is solar fuels rather than electricity.
- EnergyNest: EnergyNest provides modular thermal energy storage using a concrete-based medium, marketed to oil & gas, industrial, and renewables customers. It is an emerging player in long-duration thermal storage with partial overlap to 247Solar's HeatStore product and industrial-heat go-to-market.
Direct peers
- BrightSource Energy: BrightSource develops utility-scale CSP tower plants with thermal storage and has historically targeted industrial and utility customers with dispatchable solar. It is a direct comparable to 247Solar in CSP technology category, although at a much larger, utility-scale project size.
- Antora Energy: Antora Energy pairs low-cost thermal energy storage with a heat-to-power conversion system to deliver 24/7 clean electricity and industrial heat for C&I customers. It overlaps directly with 247Solar's HeatStore + Heat2Power architecture and is targeting many of the same decarbonization use cases.
- Brenmiller Energy: Brenmiller Energy supplies industrial-grade thermal energy storage (bTES) systems that decouple heat and power generation, with a strong focus on industrial process heat customers. It is a direct peer in the thermal-energy-storage and industrial-decarbonization space that 247Solar is pursuing.
- Heliogen: Heliogen is a direct competitor in high-temperature concentrated solar power, developing a similar architecture for dispatchable solar heat and power targeting industrial and mining customers. It is the closest comparable to 247Solar in product, customer base, and EaaS-style commercialization.
- SolarReserve: SolarReserve pioneered CSP plants with molten-salt thermal storage targeting utility-scale dispatchable solar. It is a direct comparable to 247Solar in CSP-with-thermal-storage architecture, though focused on much larger utility-scale projects and currently operating with limited new development activity.
Regional players
- GlassPoint Solar: GlassPoint builds enclosed trough solar steam generators for industrial process heat, primarily in the Middle East. It is a regional player with partial overlap to 247Solar's high-temperature solar thermal product and industrial-heat customer base, but focused on oil & gas steam applications.
Broad incumbents
- Siemens Energy: Siemens Energy supplies large gas turbines, grid-scale power generation equipment, and increasingly integrates energy storage with renewables. It is a broad incumbent competing with 247Solar for industrial and utility customers seeking dispatchable clean power, particularly in the data-center vertical.
- Abengoa: Abengoa is a long-established EPC and technology company with a large portfolio of utility-scale CSP projects (parabolic trough, tower) using molten-salt storage. It is a broad incumbent in CSP plant development and EPC that competes with 247Solar for industrial and utility customers seeking dispatchable solar, though at much larger project scale.
