What Magaldi Green Energy does
Magaldi Green Energy (MGE) is an Italian private deep-tech startup, founded in October 2021 as a spin-off of Magaldi Power SpA, that develops and commercializes fluidized sand-based thermal energy storage systems for industrial decarbonization. Its core product, MGTES (Magaldi Green Thermal Energy Storage), stores electrical or thermal energy from renewable sources in a fluidized bed of silica sand heated up to ~1000°C, then discharges it as superheated steam at 150–450°C with less than 2% daily storage losses; a complementary offering, STEM® CST, applies the same fluidized sand architecture to concentrated solar thermal power. Eleven worldwide patents protect the underlying architecture, which the company differentiates on direct immersion heating/cooling and 2–3 orders of magnitude higher thermal diffusivity vs. fixed-bed competitors such as molten salt systems. MGTES is targeted at energy-intensive industrial heat users in food & beverage, chemicals, cement, steel, and pharmaceuticals, with secondary applications in district heating and grid ancillary services.
The company operates a hybrid revenue model spanning capital equipment sales of custom MGTES systems, technology licensing on its 11 patented inventions, and a managed green-steam service delivered through its partnership with Enel X. Its go-to-market combines direct enterprise field sales to large industrial customers, a flagship channel partnership with Enel that embeds MGTES into Enel's flexibility solutions portfolio, and a regional headquarters in Dubai Science Park serving GCC markets. MGTES is sold on a custom-priced basis per installed power, thermal capacity, and steam specification. The company has two demonstrated installations to date: the world's first industrial-scale STEM® CST plant at A2A's San Filippo del Mela integrated energy hub in Sicily (2 MWth, 786 heliostats, 12,000+ validated operating hours) and the first commercial full-scale MGTES plant inaugurated September 2025 in Buccino serving I.GI. S.p.A. (7.5 MWh capacity, 190°C steam meeting ~15% of the customer's thermal load and avoiding 500+ tonnes CO₂/year). MGE is strategically positioned within the Magaldi Group's industrial material-handling heritage, sits on the LDES Council board alongside McKinsey, Breakthrough Energy, Baker Hughes and Ørsted, and is supported by SACE/SIMEST for export-driven internationalization.

Magaldi Green Energy product offering
Product offeringCore offering
Magaldi Green Energy designs, manufactures, and supplies proprietary thermal energy storage systems based on fluidized sand bed technology. Its flagship MGTES (Magaldi Green Thermal Energy Storage) system stores renewable electricity or thermal energy in heated silica sand and delivers medium- to high-temperature steam (150-450°C) on demand to industrial customers. The company also offers STEM-CST concentrated solar thermal plants that use fluidized sand as both a thermal storage medium and a direct heat exchanger for steam generation.
Product overview
Magaldi Green Energy offers a portfolio of thermal energy storage and concentrated solar thermal products. The core offerings are MGTES (Magaldi Green Thermal Energy Storage), a breakthrough sand-based thermal battery providing long-duration energy storage for industrial decarbonization, and STEM® CST (Solar Thermo-Electric Magaldi), a concentrated solar thermal technology. The MGTES system uses fluidized sand bed technology to store renewable energy and release high-temperature heat (150-450°C) for industrial processes, while STEM® CST harnesses solar radiation for combined power and heat generation. Both technologies share the innovative fluidized sand approach developed from Magaldi's expertise in high-temperature material handling, with supporting documentation and control systems available.
