Uncompromising safety, maximum purity and maximum efficiency: with BAUER KOMPRESSOREN's complete H₂ solutions, you are ideally equipped for the green energy future. 

Green hydrogen (H₂) is the key to a climate-neutral energy supply. As the market leader in gas compression, BAUER KOMPRESSOREN offers tailor-made complete systems for safe and efficient H₂ compression – individually designed for your application. 

From planning and compression to distribution, we offer turnkey solutions that meet all requirements for safety, purity (DIN EN 17124 / ISO 14687) and economy – including 24/7 service if desired. 

1. Compression 

The gaseous hydrogen is compressed to 250–330 bar depending on the inlet pressure (a few mbar to 4 bar). 

2. Gas preparation 

The BAUER special filter system of the P-XXX-H series removes water, aerosols and other impurities. The result: H₂ in tested standard purity – safe and efficient. 

3. Storage 

The purified gas is temporarily stored in high-pressure cylinders at up to 330 bar – optionally in three storage banks (high/medium/low pressure) to achieve maximum efficiency. 

4. Distribution 

Whether for vehicle refuelling, engine test bench trials or laboratory systems: we offer the right system solution for your application. 

Your project – our advice: 

We analyse all relevant parameters and provide the technical and economic basis for your investment decision: 

• Gas demand: How much H₂ per hour or day? We calculate the optimal dimensioning. 
• Pre-pressure: Higher inlet pressure saves energy – we show you how. 
• Storage size: Planned according to requirements for peak loads and safety. 
• Treatment capacity: Filter service life & maintenance intervals – precisely coordinated. 

Whether indoor or outdoor, small business or industrial application: 

BAUER delivers future-proof systems – tailored precisely to your needs.
