Hydrogen plant process monitoring system

Home » Sectors » Hydrogen plant process monitoring system

The future of energy lies in renewable hydrogen: a versatile and non-polluting energy vector produced from renewable sources, from which clean energy can be obtained with high yields and zero CO2 emissions. Renewable hydrogen represents the future of energy generation, focused on industrial decarbonisation and climate neutrality.

At Envira, we understand the complexity of processes involving hydrogen and, thanks to our experience, we can design and offer specific and certified process instrumentation solutions for each stage: analysers, gas chromatographs, flowmeters, pressure gauges or temperature probes, among others.

In this way, our systems are adapted to the different hydrogen processes in all their variations: green, grey, blue, turquoise and pink.

Presence across the value chain

As specialists in the monitoring of air and water quality, our instrumentation is able to cover the entire hydrogen value chain, providing advice and solutions at every stage: production, storage, distribution, transport and specific use in various applications.

Applications & Uses

H<sub>2</sub> Production

H₂ Production

We offer specific solutions and instrumentation for both the SMR process in HyCO plants and for the production of renewable hydrogen using a PEM, alkaline or SOEC electrolyser system, monitoring the quality of the ultra-pure water.

Purity Measurements

Purity Measurements

Our instrumentation ensures the purity and uniform composition of H₂ in its production and distribution for use in fuel cells, according to ISO 14687:2019, EN 17124:2018 and SAE J2719.

Decarbonisation

Decarbonisation

The substitution of fossil fuels by green H₂ in industry makes it possible to eliminate CO₂ emissions, but this requires instrumentation to control the quality, safety and optimisation of production processes.

H<sub>2</sub> Liquefaction

H₂ Liquefaction

Liquid hydrogen is easier to store, transport and handle, but its conversion requires extremely low temperatures and hydrogen purity at the input to the process, which requires specific instrumentation.

Renewable Hydrogen Fuel

The use of hydrogen from renewable sources as a raw material in various industrial sectors is a tool for industrial decarbonisation, as it allows a significant reduction of CO2 in processes such as

Ammonia and methanol production in the chemical industry.
Desulphurisation and hydrotreating of fossil fuels in refineries.
Replacing coal in direct iron reduction (DRI) in steel production.
Production of sustainable synthetic fuels in combination with captured CO2.

AIP Fuel Cells

Hydrogen generation from bioethanol or ethanol is a promising technology for use in Air Independent Propulsion (AIP) hydrogen fuel cells, a method particularly useful in applications such as submarines where the ability to operate without access to outside air is a significant advantage.

At Envira we have a wide range of process specific instrumentation including gas analysers, oxygen detectors, pressure and temperature gauges and even air quality monitors to detect fugitive emissions to the environment.

Certified process instrumentation

Hydrogen is highly flammable and can form explosive mixtures in air at certain concentrations, so for both operational safety and regulatory compliance, the renewable hydrogen industry requires SIL (Safety Integrity Level) and ATEX (Explosive Atmospheres) certified instrumentation such as that which we can offer at Envira.
