Hydrogen & Green Gases

Mix hydrogen, green propane and other demanding media safely and precisely. Gasyco designs mixing systems for the energy transition, from H₂ blending into the natural gas grid to the complete replacement of natural gas with propane.

Applications

Three routes to renewable gas, built by Gasyco.

01

Blending hydrogen into natural gas

Keep the H₂ share in natural gas stable – even when demand fluctuates.
H₂CH₄
Task

Hydrogen is to be fed into natural gas at a fixed share. The share must stay stable even when demand fluctuates.

Solution

The Gas Mixer GAMI controls the H₂ share digitally. The Gas Analyser GAN monitors the composition continuously and reports every deviation.

Key figures
H₂ sharefreely adjustable, typically 2 – 20 vol.%
Mixing accuracy± 0.3 % FS + ± 0.5 % of reading
Flow rateup to 300 m³n/h, larger on request
AnalysisH₂ continuous, 0 – 100 %
02

Hydrogen combined with green propane

Green propane compensates for the lower calorific value of hydrogen – gas quality stays the same.
H₂C₃H₈
Task

Per cubic metre, hydrogen has a significantly lower calorific value than natural gas. Gross calorific value and Wobbe index should nevertheless stay within the target range.

Solution

Green propane compensates for the lower calorific value. The mixer controls both components so that your appliances receive a constant gas quality.

03

Green propane as a replacement for natural gas

Switch natural gas consumers to renewable gas – without converting burners or systems.
C₃H₈Air
Task

Existing natural gas consumers are to be switched to renewable gas without converting burners and systems.

Solution

Propane is mixed with air until it reaches the combustion properties of natural gas. Your appliances keep running as before.

Key figures
Mixing ratioapprox. 55 – 60 % propane in air
Wobbe indexat natural gas H level, approx. 13.6 – 15.7 kWh/m³

VerificationO₂ analysis confirms the air share
Custom-designed

Your application is as individual as your gas.

The key figures show typical designs. We always plan hydrogen and fuel gas systems on a project basis – with a safety concept, suitable materials, explosion protection and special requirements that go beyond the standard. Many of these solutions therefore cannot be fully represented in the configurator.

Safety

Safe with hydrogen and critical media.

Hydrogen diffuses easily, embrittles unsuitable materials and is highly flammable. Corrosive and toxic gases attack components. That is why we select materials, seals and safety technology individually for each medium.

01

Materials

All wetted parts are made of stainless steel inside, combined with seals suitable for hydrogen.

02

Leak-tightness

Every system is leak-tested before delivery.

03

Explosion protection

Technically, our devices are permanently leak-tight. Together with TÜV we have assessed this: no explosion hazard comes from the device. An ATEX-certified version is possible as a custom solution.

Assessed with TÜV

04

Safety shutdown

SIL Gas Control monitors up to SIL 3 and shuts down safely in the event of a fault.

Gases

The gases we process.

A selection of the media our systems already work with. The list is deliberately not complete: we select materials, seals and sensors to suit each gas – and can therefore process far more media and mixtures than are listed here.

Is your medium missing? We check every application individually.

Frequently asked questions

The right questions. The right answers.

How much hydrogen can be blended into natural gas?

The H₂ share can be set freely, typically 2 to 20 vol.-%. The Gas Mixer GAMI keeps it stable even when demand fluctuates, and the Gas Analyser GAN continuously monitors the composition. Typical designs go up to 300 m³n/h, larger systems on request.

Can I replace natural gas with green propane?

Yes, without converting burners or systems: propane is mixed with air, around 55 to 60 % propane, until it reaches the combustion properties of natural gas – the Wobbe index is then at natural gas H level. An O₂ analysis confirms the air content.

Are the systems explosion-protected for hydrogen?

Our devices are permanently leak-tight by design; together with TÜV we assessed that the device itself poses no explosion hazard. Wetted parts are made of stainless steel inside with seals suitable for hydrogen, and every system is leak-tested before delivery. An ATEX-certified version is available as a custom solution.
