Jun 19, 2025 · According to a 2023 report from the trade association Long Duration Energy Storage Council (LDES Council)—of which Malta Inc., is a member and Breakthrough Energy
Mar 1, 2021 · "Malta''s innovative application of well-established technologies and materials could accelerate the roll out of long-duration storage to support the transition to fully dispatchable
Using common, cost-effective materials like molten salt, steel, anti-freeze, and air—they designed a system that can store energy and release it on demand, even days or weeks later. Renewable energy is gathered from wind or solar farms on the grid as electrical energy and sent to Malta’s energy storage system.
Today Malta is in advanced discussions with a more than a dozen utilities in Europe, and the Americas over plans to deploy Malta’s long duration energy storage technology. As the urgency of the energy transition grows, interest in Malta’s ready-to-market, thermo-electric energy storage solution has skyrocketed.
Malta was formed as an independent company, outside of Alphabet, in December 2018. Today Malta is in advanced discussions with a more than a dozen utilities in Europe, and the Americas over plans to deploy Malta’s long duration energy storage technology.
Malta’s system also achieves a power-to-power charge/discharge round-trip efficiency (RTE) of up to 60%, which is about 50% higher than other thermal storage systems without heat pump charging.
Malta was incubated at X, Alphabet’s Moonshot Factory, which identified the Malta system as a product that had the potential to unlock a wealth of inexpensive clean energy to address global energy demands.
A: A Malta storage unit can be charged and discharged 100% in unlimited cycles without degradation of the storage media. As the main storage medium, Malta has selected a natural thermo-solar salt sourced by solar evaporation (e.g., in the Atacama Desert of Chile).
The global residential solar storage and inverter market is experiencing rapid expansion, with demand increasing by over 300% in the past three years. Home energy storage solutions now account for approximately 35% of all new residential solar installations worldwide. North America leads with 38% market share, driven by homeowner energy independence goals and federal tax credits that reduce total system costs by 26-30%. Europe follows with 32% market share, where standardized home storage designs have cut installation timelines by 55% compared to custom solutions. Asia-Pacific represents the fastest-growing region at 45% CAGR, with manufacturing innovations reducing system prices by 18% annually. Emerging markets are adopting residential storage for backup power and energy cost reduction, with typical payback periods of 4-7 years. Modern home installations now feature integrated systems with 10-30kWh capacity at costs below $700/kWh for complete residential energy solutions.
Technological advancements are dramatically improving home solar storage and inverter performance while reducing costs. Next-generation battery management systems maintain optimal performance with 40% less energy loss, extending battery lifespan to 15+ years. Standardized plug-and-play designs have reduced installation costs from $1,200/kW to $650/kW since 2022. Smart integration features now allow home systems to operate as virtual power plants, increasing homeowner savings by 35% through time-of-use optimization and grid services. Safety innovations including multi-stage protection and thermal management systems have reduced insurance premiums by 25% for solar storage installations. New modular designs enable capacity expansion through simple battery additions at just $600/kWh for incremental storage. These innovations have improved ROI significantly, with residential projects typically achieving payback in 5-8 years depending on local electricity rates and incentive programs. Recent pricing trends show standard home systems (5-10kWh) starting at $8,000 and premium systems (15-20kWh) from $12,000, with financing options available for homeowners.
