What ATOM H2 does
ATOM H2 (legally ATOM H2 ENERGYTECH S.L.) is a Barcelona-based private company developing modular hydrogen-based backup power systems for businesses with critical infrastructure. The core product combines a PEM electrolyser (0.5-2.5kW), solid-state hydrogen storage (22-242kWh), a fuel cell (2-6kW output), and configurable lithium batteries (10-120kWh) inside an 8-foot container (2020x2140x2072mm) with scalable solar panels, designed to autonomously capture surplus renewable energy and deliver zero-emission backup power as an alternative to diesel generators.
The company's target customer segments are enterprises with critical power needs (data centers, hospitals, telecoms, industrial facilities), renewable energy operators needing long-duration storage beyond batteries, and organizations transitioning away from diesel. The system is marketed as fully autonomous and self-managed, combining lithium batteries for immediate response with hydrogen storage for extended autonomy. A next-generation V2 system is in preparation, with the company currently accepting pre-pilot applications.
Commercially, ATOM H2 operates a direct enterprise sales motion via its website (contact/demo request CTAs), targeting B2B buyers for custom-configured container deployments. Pricing is quote-based and not publicly disclosed. The company has not disclosed funding rounds, revenue, or named customers, and operates with a small team (1-10 employees) led by CEO Anna Martin, COO Marcel Rovira, CTO Lucas Vicen, and CMO Mariona Figueras. It has won the 2025 Santander X Spain Award and the 2026 Premios EmprendeXXI in Catalunya and has established research and academic partnerships to support R&D.

ATOM H2 product offering
Product offeringCore offering
ATOM H2 designs, manufactures, and sells modular hydrogen-based backup power systems that combine solid-state hydrogen storage, PEM electrolysers, fuel cells, and lithium batteries in an 8-foot container format. The systems store surplus renewable energy and provide zero-emission backup power for critical infrastructure, designed to replace diesel generators. The product is configurable from 10kWh to 242kWh storage capacity and is targeted at businesses with critical power continuity needs.
Product overview
ATOM H2 offers a single unified hydrogen-based backup power product that combines solid-state hydrogen storage with lithium batteries. The core ATOM H2 system integrates multiple functional components: On-Demand Renewable Power (for immediate energy needs), Solid H₂ Storage (long-duration hydrogen storage 22-242kWh), Reliable Backup (replacing diesel generators), and Zero-Emission Power delivery. The system uses PEM electrolyser (0.5-2.5kW), configurable lithium batteries (10-120kWh), hydrogen storage, and fuel cells (2-6kW output) in an 8-foot modular container format. The company is developing a V2 solution for future release.
