What Nostromo does
Nostromo Energy designs and manufactures the IceBrick, a modular ice-based thermal energy storage system intended for behind-the-meter installation in commercial, industrial, and data center buildings. Each IceBrick cell encapsulates water and glycol coolant that is frozen during off-peak hours and discharged during peak hours to shift cooling loads; arrays scale from 20 cells (~200 kWh) to 1,000+ cells (10+ MWh-equivalent, 200 to 10,000+ ton-refrigeration-hours). The system is managed locally by an on-site controller and remotely by the Cirrus cloud platform, which applies AI/ML for optimization, predictive analytics, ESG reporting, and grid integration including CAISO market participation via a partnership with Olivine.
The company was founded in Israel in 2017 by Yaron Ben Nun and listed on the Tel Aviv Stock Exchange (TASE: NOST) before completing a voluntary delisting in August 2024; it now operates with US headquarters in Irvine, California. Revenue mechanics span direct hardware sales (eligible for 40% ITC plus domestic content adder), an Energy Storage as-a-Service program routed through the IceBrick Energy Development subsidiary and backed by a conditional $305.5 million DOE loan guarantee, third-party lease financing, and grid/demand response revenue. Named enterprise customers include The Beverly Hilton, The Waldorf Astoria Beverly Hills, Soroka University Medical Center, and Hartsfield-Jackson Atlanta International Airport, with a DOE-backed deployment pipeline of up to 193 California commercial buildings and the November 2025 launch of IceBrick360 targeting data center speed-to-power constraints.
The company operates primarily in the United States (California, Texas, Georgia) with continued presence in Israel. Leadership includes CEO Yoram Ashery, Founder/CTO Yaron Ben Nun, CFO Nir Vaiman, CBDO Boaz Ur, and a US commercial operations team led by VP Doug Poffinbarger. The company holds ISO 9001:2015 and ISO 27001 certifications, is a member of ASHRAE, CESA, CALFlexHub, and Stor4Build industry associations, and was recognized with a 2024 ASCE Metropolitan Los Angeles Branch Outstanding Energy Project Award for the IceBrick Innovation Center at the Beverly Hilton.

Nostromo product offering
Product offeringCore offering
Nostromo manufactures and sells the IceBrick thermal energy storage system, a modular behind-the-meter solution that freezes water/glycol solution into ice cells during off-peak electricity hours and discharges the stored cooling during peak hours to reduce demand charges and energy costs in commercial, industrial, and data center facilities. Systems scale from 200 kWh to more than 10 MWh-equivalent per site, integrate with facility chilled water loops, and are managed by the Cirrus AI-powered cloud platform. The company also offers an Energy Storage as-a-Service (ESaaS) financing model with zero upfront cost to building owners.
Product overview
Nostromo offers a modular ice-based thermal energy storage system called IceBrick, which serves as the core product platform. The system comprises modular IceBrick Energy Storage Cells that can be configured into Arrays (200 to 10,000+ ton refrigeration hours), managed by an On-Site Controller, and optimized via the Cirrus Cloud-Based Management Platform. IceBrick360 is a data center-specific variant. The company provides both direct purchase and Energy Storage as-a-Service (ESaaS) financing models. The system shifts cooling loads from peak to off-peak hours, enabling grid-interactive demand flexibility for commercial buildings, data centers, and industrial facilities.
