The facility is designed for 1,000 tonnes per day, totaling roughly 365,000 tonnes per year, making it Latin America’s first large-scale dedicated solar glass plant.
The plant will be located beside high purity, low-iron silica sand resources owned by Homerun, reducing input costs and logistics, and ensuring consistent supply of premium feedstock for solar. glass manufacturing
Secured offtake agreements already exceed 300,000 tonnes annually and are expected to surpass plant capacity, reflecting high market demand and solid revenue visibility from leading Brazilian solar module manufacturers
The solar glass manufacturing budget is estimated at €150 million, with additional funds for construction and utilities. Homerun is engaging with international financial syndicates for capital funding including discussions with the industrial development bank of the Brazil Government (BNDES) where Homerun has recently received a Joint Support Plan for funding.
Brazil recently imposed a 25% tariff on imported Chinese solar components, including glass, and expanded tax incentives for domestic supply, protecting Homerun’s pricing power and profitability
The plant will incorporate advanced energy-efficient systems and flue gas treatment for low emissions. Natural gas will be used as the primary energy source, with additional measures for environmental compliance.
Homerun expects to create up to 500 direct jobs, 2,800 indirect jobs, and 1,000 temporary jobs during construction, plus technical training programs and regional infrastructure upgrades
A Memorandum of Understanding secures land donation from the municipal government, expedited permitting, dedicated natural gas supply, and substantial tax incentives for Homerun’s projects in Bahia
Owning both the raw silica resource and glass manufacturing allows for cost control, reduced supply chain risks, and enhanced margins, positioning Homerun as a market leader in Brazil’s surging solar sector
The solar glass will be sold FOB (Free On Board) the plant in Belmonte, Brazil. Once goods are on board, risk and costs transfer to the buyer, who becomes responsible for marine freight, insurance, unloading, import clearance, and onward carriage.

NREL developed system components and projected that the component designs meet the cost and performance targets for demonstration and technology to market. The ENDURING LDES system provides power for several days by low-cost, high-performance storage cycles, addressing grid storage needs by enabling large-scale grid integration of variable renewables like wind and solar, thereby increasing their grid value. Five awarded patents, 8 published journal papers, and a book chapter.
Using stable, inexpensive silica sand in insulated concrete silos, the low-cost, large-scale system provides electric storage at a cost of 5¢/kWh.
The project has screened and tested material stability of storage media and the thermal insulation solutions at the applied storage temperature (1200°C). Preliminary component designs have confirmed the feasibility and realizability of the ENDURING system. The project successfully developed and tested key component prototypes including an electric charging heater and a pressurized fluidized-bed heat exchanger. The pilot system is being built in Colorado.
Near-term market can convert retiring thermal power plants to grid storage for electricity arbitrage.
The technology has been developed over 15 years and over USD $20M in RD&D efforts supported by the DOE.
The ENDURING system works by heating stable, low-cost solid silica particles – which unlike molten salts, are stable at both high and ambient temperatures—to over 1,000 degrees Celsius. This charging process happens when electric power is cheapest, allowing the resulting energy to be stored for several days in large storage modules. To discharge this energy, the hot particles are fed through a heat exchanger, ultimately driving an electric generator.
The ENDURING project is developing a low-cost particle-based thermal energy storage for 10–100 hours, 50–400 MWe grid electric storage. The energy storage system provides reliable, affordable power to the electric grid.
Yes, the ENDURING System will integrate directly with nuclear resulting in utility grid power, distributed energy and energy security.
Circulating sand particles over charging/discharging devices with high heat capacity and efficiency compared to the incumbent technologies that all circulate air. Separate storage and heat exchangers for charging/discharging by circulating particles enables free scaling up of storage capacities comparing to incumbent TES charging/discharging whole storage containment. Silica sand mined from ground at a cost about $30-40/ton for <$10/kWht storage cost, substantially lower than other storage media and can supply heat over a wider temperature range (firebricks >$1/kg), and safer (no fire hazard like graphite in other storage systems).
