Process overview
The hydrogen ecosystem
Hydrogen enables decarbonization, renewables integration, and zero-emission mobility. Its cleanliness and multi-sector applicability provide a holistic approach to clean energy. Global demand comes from refineries, ammonia production, and other industries. Hydrogen production sources include fossil fuels, industrial processes, biomass, and renewables. It is classified as grey, blue, or green based on its source and transported via pipelines, trucks, or ships in gaseous or liquid phase (LH2).

Hydrogen injection in natural gas grid
Hydrogen can be transported using the existing natural gas infrastructure depending on the pipelines. Every incremental amount of hydrogen injected into a natural gas fuel system or pipeline abates some amount of methane, and thus CO₂. Injection percentages can vary from 10-20% as per the regulations. Relying on accurate flow and composition measurement technology is critical to ensure both quantity and quality of the blends.
Our expertise in the field
By using Endress+Hauser Coriolis flowmeters, it is easy to measure with high accuracy, stability and ultimately control, the flow of hydrogen into the natural gas grid appropriately. To determine the final mix ratio, you can rely on

Measuring water quality for green hydrogen production
The electrolysis process requires ultrapure water. To produce 1 kg of hydrogen, 9 kg of ultrapure water is used, which means roughly 30 kg of seawater. Water not meeting quality requirements could impact smooth operation of the electrolyzer thereby increasing OPEX. Conductivity is the leading quality parameter. It is generally limited to <1 μS/cm for alkaline electrolyzers and <0.1 μS/cm for PEM electrolyzers.
Our expertise in the field
Sea water is a vital source considering scarcity of fresh water in parts of the world. Consequently, distinct treatment steps are necessary to achieve the required water purity for electrolyzer operation. The quality of the feedwater supplied to the reverse osmosis (RO) membrane needs to be closely monitored to control efficiency, trigger cleaning or regeneration and ensure adequate water quality. Endress+Hauser offers a wide range of sensors and analyzers to monitor these processes.
