Bulgaria’s first Hydrogen Valley starts in Stara Zagora

ZAHYR is building a new green hydrogen ecosystem — connecting clean energy, mobility, industry, education and regional transformation.

What is ZAHYR?

A cleaner future needs a starting point

Stara Zagora Panorama

Stara Zagora is one of Bulgaria’s key energy regions.

Today, the region faces the challenge of transition — from coal-based energy towards cleaner technologies, new skills and long-term economic opportunities.

ZAHYR responds to this challenge by demonstrating how green hydrogen can support cleaner transport, industrial innovation, better air quality and a more resilient regional economy.

Connecting Hydrogen

How ZAHYR links energy, hydrogen, mobility, industry and people.

Clean Energy

Renewable energy will support the production of green hydrogen.

Hydrogen

Hydrogen will be produced locally from multiple sources: ammonia and water.

Clean Mobility

Hydrogen will support the transition of logistics and public transport towards lower-emission.

Industry

The project will test hydrogen applications in heating and industrial processes.

Education

ZAHYR will support awareness, training and dialogue with citizens, businesses and institutions.

How ZAHYR works?

It combines two technologies in a single integrated system: an electrolyser (150 kg/day production) powered by renewable electricity, and an ammonia cracker (125 → 1,500 kg/day production). They complement each other: when solar availability is low, the cracker runs; when electricity is cheap, the electrolyser runs.

More robust, more resilient.

Real trucks and buses carry real freight and people.

A real boiler heats real building.

A real fertilizer producer uses hydrogen in its industrial process.

ZAHYR demonstrates the pathway to new business.

Hydrogen begins with understanding

ZAHYR creates space for dialogue between young people, citizens, researchers, businesses and institutions. Transition only works when people understand it, question it and can be part of it.
