Bosch Starts 2.5MW Electrolyzer, Meets EU Hydrogen Rules

• Bosch launches a 2.5 MW PEM electrolyzer in Bamberg, making over one ton of green hydrogen daily—EU-compliant, locally built, and fueling long-haul FCPM tests in a closed-loop “lifetime” setup.

Bosch has commissioned its first self-operated hydrogen electrolyzer at its Bamberg, Germany, site: a 2.5 MW PEM system using two Hybrion stacks. The in-house unit complies with EU renewable hydrogen rules requiring temporal matching and same-price-zone proximity. The stacks, built in Bamberg and integrated by FEST GmbH in Goslar, can produce 23 kg of green hydrogen per hour.

At full load, the system yields over one ton of green hydrogen daily—enough to power a 40-ton electric truck with Bosch’s Fuel Cell Power Module (FCPM) for up to 14,000 km. Bosch will run the FCPM continuously in a “lifetime container,” using on-site hydrogen to test long-term performance, feeding generated electricity back to the electrolyzer and simulating multiple operating scenarios.

How will Bosch source renewable electricity to meet EU temporal-matching hydrogen rules?

• Build/expand on-site renewables (rooftop/ground PV, possibly small wind) with certified metering to timestamp output
  
• Sign hourly matched PPAs with new-build wind/solar in the DE-LU price zone, backed by timestamped Guarantees of Origin/EACs
  
• Use direct-wire connections to nearby renewable plants to strengthen geographic correlation
  
• Source intraday top-ups from utility/aggregator portfolios that deliver RFNBO-compliant, hour-by-hour matched renewables
  
• Add battery buffering to shape variable PV/wind to electrolyzer demand without breaking hourly correlation
  
• Operate the electrolyzer flexibly—run in matched hours, ramp down or pause in unmatched hours
  
• Join/localize supply via municipal utility or energy-community arrangements for priority access to local, timestamped renewables
  
• Contract curtailed/redispatch renewable volumes within the bidding zone to increase low-cost, matchable hours
  
• Implement a digital compliance stack: revenue-grade meters at the electrolyzer, registry-linked certificates, automated hourly reconciliation and audit trail
  
• Transition plan: use daily matching where permitted now, migrate to full hourly matching by 2030; ensure additionality via PPAs tied to new capacity
  
• Maintain hydrogen storage and procure renewable balancing energy as contingency to stabilize operations while preserving temporal matching
