What Ourea Energy does

Ourea Energy is a private clean-technology company headquartered in Chicago, Illinois (USA), founded in 2025. It develops GravityBank, a gravity-based long-duration energy storage platform built on packaged pumped-hydro principles. The company sells GravityBank systems through bespoke enterprise engagements to three target segments: electric utilities (its primary segment), data-center operators, and industrial manufacturing plants, with disclosed operating geographies in the Western United States and Mexico.

The GravityBank platform is offered in three configurations: the GB600, a 600-meter utility-scale tower that stores 1 GWh of energy for grid-scale deployments; the GB300, a modular campus-scale unit positioned next to data centers or manufacturing plants to deliver on-site storage, cooling, and water resilience; and an Integrated variant built directly into the fabric of a building so that the structure itself becomes part of the energy infrastructure. Per company disclosures, the system delivers three quantifiable benefits — approximately 50% reduction in data-center cooling load, 1 GWh of long-duration storage per GB600, and roughly 200 million gallons of water held in reserve per installation. The technical foundation is sourced from Energy Vault's gravity-based storage knowledge base, with architecture, engineering, and design contributions from SOM (Skidmore, Owings & Merrill); the company positions GravityBank against a DOE-cited prediction of a 100x increase in blackouts by 2030.

Ourea Energy generates revenue through the sale and deployment of GravityBank infrastructure systems as long-term capital assets rather than via standardized pricing or SaaS contracts. Go-to-market is direct enterprise field sales, with major execution and market-development handled through strategic and implementation partners including Laing O'Rourke, Stantec, Doka, Idea Lab AZ, and Rise Global. Pricing is not publicly disclosed and is quoted project by project. The company is led by Co-founder and CEO Adam Semel, who is concurrently a Partner at SOM, and as of the available data has completed one funding round of $250,000 on 2026-06-16.

Core offering

Ourea Energy designs and sells the GravityBank platform, a gravity-powered energy storage system that stores electricity by lifting composite blocks and releases it by lowering them through regenerative drives. The product line includes the GB600, GB300, and an Integrated variant that combines generation and storage for utility, data center, and industrial customers.

Product overview

GravityBank is a single unified energy infrastructure platform by Ourea Energy that delivers a triple-benefit of energy storage, thermal energy management, and water security. The platform comes in three product configurations: the GB600 (utility-scale flagship with a 600-meter tall tower storing 1 GWh), the GB300 (modular campus storage for data centers and manufacturing plants), and the Integrated variant (built directly into building structures). All three configurations leverage gravity-based storage technology—packaged pumped hydro—to provide long-duration energy storage alongside 50% cooling load reduction and up to 200 million gallons of water resiliency per installation. The platform is built in partnership with SOM (design), Energy Vault (technology), and other strategic partners including Laing O'Rourke, Stantec, Doka, Idea Lab AZ, and Rise Global.

Brands

• GravityBank: Energy storage solution platform that packages energy storage, thermal energy management, and water security. Includes GB600 (utility-scale flagship), GB300 (modular campus storage), and integrated building solutions.

Products and services

• GravityBank GB600 A modular gravity-based long-duration energy storage unit in the GravityBank family, designed for utility, data center, and industrial customers needing scalable storage capacity. It stores electricity by lifting composite blocks and discharges through regenerative drives with no thermal or chemical degradation.
• GravityBank GB300 A smaller-capacity modular gravity-based energy storage unit in the GravityBank family, targeted at customers with lower-capacity needs. Stores electricity by lifting composite blocks and generates power from regenerative drives on descent.
• GravityBank Integrated A turnkey, site-ready variant of the GravityBank platform that combines generation and storage in a single integrated system for utility, data center, and manufacturing customers.

Others

• Laing O'Rourke: International construction engineering group and named implementation partner for Ourea's GravityBank deployment. Comparable as an enabling ecosystem participant delivering the construction backbone for Ourea's infrastructure projects.
• Stantec: Global design and consulting firm and named implementation partner for Ourea. Comparable as an enabling ecosystem participant providing engineering services, and a reference for the type of large infrastructure firms in Ourea's execution consortium.

Direct peers

• Gravitricity: UK-based developer of gravity energy storage systems that lift and lower heavy masses in mine shafts. Closely comparable technology category (gravity/solid-mass LDES) targeting grid-scale long-duration storage applications.
• Energy Vault: Public gravity-based energy storage developer and Ourea's named technology partner. Directly comparable because both use lifted-weight/pumped-hydro principles for utility-scale long-duration storage, but Energy Vault is significantly further along in commercialization and project deployment.
• Form Energy: Developer of iron-air battery systems for multi-day grid storage. Comparable as a long-duration energy storage competitor targeting electric utilities and the same 100+ hour storage market that Ourea's GB600 addresses.
• ESS Inc. Manufacturer of iron flow batteries for long-duration commercial and utility-scale storage. Comparable target customer (utilities, data centers, microgrids) and competitive position in the long-duration energy storage market.
• Highview Power: Developer of liquid air energy storage (LAES/cryogenic) for utility-scale long-duration applications. Directly comparable as a non-lithium, physics-based long-duration storage technology competing for the same utility and grid-resiliency RFPs.

Emerging players

• Malta Inc. Developer of pumped heat thermal storage systems for long-duration grid storage, spun out of X (formerly Google X). Comparable as an emerging long-duration energy storage technology targeting utility and grid applications.
• Quidnet Energy: Developer of compressed air energy storage using subsurface geology. Comparable as a non-lithium, physics-based LDES technology targeting utility-scale long-duration applications, though with a different storage mechanism than gravity.

Broad incumbents

• Tesla (Energy / Megapack): Largest commercial battery storage provider (Megapack) with extensive data center and utility deployments. Comparable target customers and grid-scale storage category, though Tesla focuses on lithium-ion BESS rather than gravity-based LDES.
