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 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.
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.
