The US Department of Energy website maps out (link) the majority of energy storage systems in the world today. The 1,756 storage systems tallied on the site represent a total of ~196,000 MW. Filtering out non-ice TES systems, we are left with only 102 MW ice TES systems. In other words, currently, ice storage accounts for only one-twentieth of one percent of all available storage. 

For that very reason, it is vitally important to understand the competitive landscape in which Nostromo is operating, or maybe: How come water is losing to lithium?

The answer is that the products currently on the market simply do not fit current market needs, and so no one wants to adopt them. Energy storage analysts ignore water-based storage solutions because they are simply not good enough.

It turns out that not one hotel or shopping mall in the US has an ice-based energy storage system. While there are a few office buildings using these systems, they are nothing more than the manufacturers’ display window, and the vast majority of ice TES systems are installed in colleges and universities.

Nostromo competes for the commercial market—hotels, hospitals, factories (with the need for cold water for manufacturing), shopping malls, office buildings, air terminals—all commercial AC consumers, which account for about 60% of all AC consumers.

While there are some niche companies—include Viking, which mainly creates storage systems for cooling down massive warehouses; Axiom, which mainly focuses on supermarkets; and Ice Energy, which currently focuses on the home market—Nostromo’s main competitors are CALMAC (recently acquired by Trane), Baltimore Aircoil, and FAFCO.

A perfect system would be one that you don’t even know is there; one whose installation a manager would have no qualms about approving. Such a system would rule the market. Nostromo has developed a system that serves as an extension to the building or as a modular part in it. With Nostromo, decision-makers needn’t struggle to pick a spot for the system, because Nostromo would solve this problem in 5 minutes during the first preliminary tour of the facility.

The advantages of the IceBrick™

Tank farms are less acceptable in the commercial business environment. Perhaps that is the reason for the absence of ice thermal energy storage systems in the commercial landscape.

Our IceBrick™ is a building block that enable our customers to seamlessly build an ice storage reservoir as an extension to a building.

The decision to shift your energy usage and join the group of people who are leading the future of the grid has never been easier.

the edge

The only potent way to improve the demand-supply chain of electricity is with energy storage. The world is fast adopting energy storage technologies—mainly electrochemical solutions, e.g., batteries.

These systems have tremendous downsides, such as safety issues, high degradation, the near impossibility of recycling, and harmful effects on the environment during the extraction of the raw materials involved.

Meanwhile, the cooling demands of commercial buildings can be easily satisfied during peak hours by discharging cold energy… ice. plain water that was transformed into ice—using cheap electricity at night or using the surplus production of solar energy.

If it’s so simple, how come Li-ion batteries dominated 94% of all 2019 new energy storage implementations? How come the stake of ice storage in the storage arena is 0.04% (link)?

The answer is that current technologies are too expensive and consist of large tanks that just don’t fit the needs of the commercial market.

Nostromo has developed the IceBrick™, a modular thermal cell that can fit any building as an extension, and it is 10 times more efficient in its energy density per square meter than any other available solution.

The system is commercially available since mid-2020 at a cost of less than $400 per kWh with a warranty for zero degradation of the cells over 10 years of operation.

Our first commercial demo system (160 ton-hr or about 200 kWh electricity equivalent) is running since June (2019).
