Our Platform

An onsite fuel cell energy platform redesigned,
from the microstructure up.

Simpler, reliable
and affordable

The EH Energy Platform is a flexible, fuel-agnostic, modular fuel cell energy platform that delivers reliable, affordable and scalable power for stationary and mobile power customers - from small drones to large AI data centers. Rooted in our patented and redesigned fuel cell microstructure, we’ve reinvented the way fuel cell power is delivered to make primary fuel cell power at large scale a reality once and for all.

Our core modules

Our platform is based on three core modules - EH Energy Stacks, EH Energy Systems and EH Power Blocks - scaling from small drone systems to large data center power plants and embedded with real-time telemetry to drive efficient operations and predictive maintenance.

EH Energy Stacks

Our fuel cell stack IP drives superior performance and large production capacity through a simplified microstructure design. Stacks come in various form factors for mobile and stationary uses.

EH Energy Systems

Our 250 kW systems are our core power module, offering modular behind-the-meter power and scalable to large-scale needs.

EH Power Blocks

Our 3 MW power blocks integrate multiple 250 kW systems with a small battery to provide a MW-scale power module with consistent baseload power.

EH Energy System

Modular 250 kW system is the foundation of our fuel cell power platform

Our performance 
advantage

Driven by our novel fuel cell microstructure, the EH Energy Platform offers simplified production, high reliability, competitive costs and instantaneous ramp times to match the dynamic loads of data center, industrial and defense customers.

Novel microstructure

Novel microstructure supports quick ramp time,
high reliability, low costs and a scalable form factor for large and small customers.

Near-instantaneous ramp

Ramp time in under 30 seconds supports dynamic loads and dramatically reduces battery requirements across projects

High reliability

System delivery with established manufacturing partners, integrated control systems and supply chains with no rare earth minerals reduces risks

Affordable

Simplified fuel cell stack design enables MW-scale stack manufacturing and system assembly with partners at costs competitive with turbines

Our production advantage

Our proprietary automated manufacturing technology has been designed from the ground up. Linked to our uniquely simplified and patented stack microstructure, each line is designed for multiple gigawatts of annual stack capacity.

We integrate our stacks into our systems, power blocks and power plants with a network of global packaging partners, offering scalable, reliable and fast time-to-power for customers.
