The world doesn't have an energy problem. It has a power deployment problem. EME hydrogen engines turn curtailed wind & solar and by-product hydrogen into reliable electricity — deployable in months, not years.
Abundant power is the defining limit of a company's potential. H2onest Clear Energy Green Power Co., Ltd. — founded June 2024 in Wuhan — is a distributed zero-carbon power innovation platform for the "AI + green hydrogen" era. EME is our engineering brand and product system.
Our technology foundation is the ammonia-hydrogen integrated high-power hydrogen internal combustion engine. Through modular architecture, we deliver high-resilience uninterrupted zero-carbon power, long-duration peak shaving and integrated hydrogen-electricity coupling for the most reliability-critical scenarios.
The engineering DNA comes from the EME team — twenty-plus years of internal-combustion-engine genset R&D, manufacturing and global delivery. We independently hold core technologies including hydrogen-injector self-lubrication, efficient stable combustion and a multi-fuel common platform.
Led by Prof. Cheng Xiaobei of Huazhong University of Science & Technology — a combustion scientist and veteran of thirteen years in engine industrial R&D — the team bridges the gap between world-class technology and commercial deployment.
Our Mission — Transform low-cost hydrogen into high-value energy. We build power that is trusted, deliverable and replicable — power as a product, not a project.
From 300kW to 2000kW — a full power range built on a single engineering platform, Hydrogen Ready from day one.
A proven combustion route — almost 100% CO₂ reduction, with NOx controlled by lean-burn and after-treatment. Like the engine you already trust, only fuelled by hydrogen. Your TCO will thank you.
First domestic hydrogen-engine genset in commercial operation — running on industrial by-product hydrogen.
In Operation · YunmengPure-hydrogen genset, performance verified. Powering zero-carbon power for chemical and mining sites.
DeliveredNatural-gas / hydrogen dual-fuel base-load gensets — today on gas, tomorrow blended, then pure hydrogen.
Hydrogen Ready · FinalisingFuel adaptability isn't a feature. It's the foundation of a resilient energy future.

Power deployment is the bottleneck — not power generation. EME hydrogen engines scale like a data center, not a power plant. Swipe or use the arrows to explore.
Every plant is recorded in a standard dossier — location, facility, fuel, status, key figures. Verifiable and traceable, replicable from 300kW to 5MW.
