Revenue model

1. Air-end component sales: Sale of patented water-injected oil-free air ends to compressor manufacturers (OEMs) for integration into their compressor products. Component sales model targeting manufacturers who want to offer energy-efficient oil-free compressors.
2. CAES system sales: Sale of complete compressed air energy storage systems for buildings and industry. The systems store electricity, heating and cooling in a single device. Market entry planned for 2025.
3. Licensing technology: Technology licensing to compressor manufacturers who integrate Green-Y air ends into their portfolios. Partnership model where Green-Y supplies components and partners shape the market.

Core offering

Green-Y develops and produces patented water-injected, oil-free screw compressor air-ends (11-90 kW, 3-40 bar) sold to compressor manufacturers (OEMs), and a Compressed Air Energy Storage (CAES) system that stores electricity while simultaneously generating usable heating (up to 60°C) and cooling (down to 3°C) for buildings and industrial applications. The technology replaces oil with water for lubrication, sealing, and cooling, delivering up to 20% higher energy efficiency than established oil-free compressors and requiring no critical raw materials.

Product overview

Green-Y develops and produces two core product lines: (1) a Compressed Air Energy Storage (CAES) System that stores electricity, heating, and cooling in a single device for buildings and industry, using compressed air at up to 300 bar with no critical raw materials; and (2) patented oil-free water-injected screw air-ends for compressor manufacturers, covering 11–90 kW and 3–40 bar, delivering up to 20% higher energy efficiency than comparable oil-free compressors. The CAES system and the air-ends are complementary — the CAES system uses compressor/expander technology at its core, while the air-ends are sold separately as OEM components to compressor manufacturers.

Functional benefit

Products and services

• Oil-Free Water-Injected Air-End Patented water-injected screw air-end for screw compressors, using water for lubrication, sealing, and cooling. Achieves nearly isothermal compression and delivers up to 20% higher energy efficiency compared to established oil-free compressors. Available in a scalable product family from 11 to 90 kW and pressure range from 3 to 40 bar. Sold to compressor manufacturers (OEMs) for integration into their compressor product lines and to industrial end-users for direct energy-cost savings.
• Compressed Air Energy Storage (CAES) System A compressed air energy storage system that stores electricity by compressing air into cylinders at up to 300 bar. During charging, compression generates heat up to 60°C (usable for space heating, hot water, or process heat). During discharge, expansion produces cold down to 3°C (usable for cooling). Targets buildings and industrial applications, with a 20-year service life, approximately 7-year amortization, and 100% recyclability using only air and water with no critical raw materials.

Direct peers

• ALMiG Kompressoren: German compressor manufacturer specializing in oil-injected and oil-free screw compressors for industrial applications. Comparable DACH-based peer competing for the same industrial end-users as Green-Y.
• Kaeser Kompressoren: German-headquartered compressor specialist with strong DACH presence and a comprehensive screw compressor portfolio including oil-free variants. Most direct geographic and product peer to Green-Y; competes head-to-head for industrial and OEM customers in Germany, Austria, and Switzerland.
• BOGE Kompressoren: German manufacturer of screw and oil-free compressors serving industrial customers across Europe. Closely comparable to Green-Y on product (oil-free screw compressors), geography (DACH), and target end-user base (industrial compressed air users).
• Hydrostor: Canadian developer of advanced compressed air energy storage (AESI/A-CAES) systems for grid-scale applications. Direct competitor in the CAES category Green-Y is entering, but focused on utility-scale projects rather than Green-Y's building/industrial scale.

Broad incumbents

• Atlas Copco: Global leader in compressors and industrial tools with broad oil-free and oil-injected product portfolios. Directly competes with Green-Y's air-end business via its own compressor R&D and serves the same industrial end-markets, but at vastly larger scale and with established OEM/global service networks.
• Ingersoll Rand: Major compressor manufacturer with extensive oil-free screw compressor offerings and global industrial distribution. Comparable to Green-Y in end-market (chemical, pharma, food, electronics) and overlapping technology (oil-free screw compression), but operates at much larger scale.
• Siemens Energy: Global energy technology major offering grid-scale storage, hydrogen compression, and industrial compressor solutions. Represents both an incumbent competitor for CAES systems and a potential large strategic partner for Green-Y in the broader decarbonization market.
• Fluence Energy: Leading global battery-based energy storage provider competing for the same distributed and industrial storage customers as Green-Y's CAES. Not a direct technology peer but a direct commercial competitor for storage budget.
• MAN Energy Solutions: Major manufacturer of large-scale compressors, turbines, and storage systems. Comparable in the high-pressure gas compression and storage space, but typically serves utility-scale and oil & gas customers rather than building/industrial markets.

Emerging players

• Energy Vault: Swiss-listed company developing gravity- and other non-battery energy storage solutions. Comparable to Green-Y's CAES ambitions on long-duration storage and Swiss origin, but uses different underlying physics (gravity rather than compressed air).
