02 · The Problem

Most power conversion issues don't show up until commissioning. By then, they're costly and difficult to reverse.

You're integrating a first-of-kind hydrogen plant. Your electrolyser OEM has strict DC power requirements. Your grid connection has its own volatility profile. And your project financiers have a go-live date that doesn't move.

Generic converters are built for shelf availability, not your sensitivity envelope. When they clash with real-world grid conditions and electrolyser specs, the result is retrofit costs, schedule overruns, and a project that misses its hydrogen production targets.

You need a power partner who starts with your spec, before manufacturing begins.

03 · Where We Fit

Precision DC power conversion for your electrolyser.

Green hydrogen projects involve a layered supply chain. Yonder's role is precise: we deliver the DC power conversion architecture that sits between the grid and the electrolyser. Understanding exactly where we contribute (and where we don't) matters to how you plan your project.

PROJECT OWNER
Project Owner / Developer

Secures offtake, sets the commercial timeline.

ELECTROLYSER OEM
Electrolyser Manufacturer

Defines the strict DC power requirements and the electrochemical sensitivity envelope.

Yonder is here
POWER CONVERSION / YONDER
Power Conversion Supplier

Yonder supplies the DC power conversion equipment to the electrolyser manufacturer or EPC contractor, engineered to the electrolyser's exact requirements.

04 · How It Works

Every system is engineered to your electrolyser.

01
Share your tech specs

Send your electrolyser manufacturer, chemistry, MW project scale, and grid parameters. Our engineers return a preliminary converter configuration with a quick turnaround.

02
We co-engineer your architecture

Unlike off-the-shelf vendors, Yonder enters at the plant specification stage. Integration issues are engineered out before a single component is manufactured.

03
We commission it with you

On-site integration directly with your electrolyser and grid tie-ins. We don't hand over a document. We stay until the plant runs.

04
Peace of mind from day one

Every system ships with an 18-month warranty, field service, and spare parts support. Extended maintenance contracts are available for ongoing coverage.

05 · Products

Built for every electrolyser chemistry. Engineered for your project.

Yonder's Power Core delivers precision DC output matched exactly to your electrolyser's sensitivity envelope, whether you're running Alkaline, PEM, AEM, or SOEC.

10 · Common Questions

What integrators ask us before shortlisting.

How early in a project should we bring Yonder in?

As early as the electrolyser specification stage. That's when we can co-engineer the DC architecture to your OEM's sensitivity envelope and avoid retrofit costs at commissioning.

Which electrolyser chemistries do you support?

Alkaline, PEM, AEM and SOEC. Our converter architectures are chemistry-agnostic and tuned to each OEM's specification.

Where do you manufacture?

Design, engineering, manufacturing, testing and QA all happen at our Pune facility in India, backed by 118 years of Ador Group heritage.

What warranty and service is included?

Every system ships with an 18-month warranty, field service and spare parts support. Extended maintenance contracts are available.

10 · Next Step
