Reliable and accurate measurements in both gas and liquid states make Rheonik Coriolis Mass Flow Meters a valuable tool in H2 and CO2 process monitoring.
Anthropogenic climate change is one of the greatest challenges of our time. To counteract the rise in greenhouse gases, measures to reduce CO2 emissions are essential. One way is to switch to renewable energy or to use energy-efficient, climate-neutral technologies and energy sources – such as hydrogen.
Hydrogen can help fight climate change and create a sustainable future in several ways. First, hydrogen can be used as a clean fuel in industry, especially in steel production. Here, hydrogen can be used as a reducing agent to separate the iron from the ore, in place of carbon. Another important application of hydrogen is mobility. Hydrogen can be used as a fuel for vehicles that produce only water as an exhaust. Fuel cell vehicles are equipped with electric motors and can achieve a range and performance similar to conventional vehicles. Finally, hydrogen can be put into storage and used to buffer intermittent renewable energy supplies.
Another option is carbon capture and storage, in which carbon dioxide is captured from the exhaust of power plants and other industrial facilities and stored in geological formations.
Building the right infrastructure for the future early on not only helps protect the environment, it can also redefine and future-proof entire business units.
Hydrogen & Renewable Energy
More and more of our energy comes from renewable clean energy sources like solar, hydro and geothermal. As technology to harness this energy has evolved, larger scale plants taking advantage of these natural resources have been created and with them, the need for performance and efficiency measurements. Rheonik Coriolis mass flow meters play a key role in ensuring energy from renewable energy sources remains part of our day-to-day energy makeup.
Rheonik & Hydrogen
Hydrogen fuel dispensers have been installed alongside gasoline and diesel dispensers in many filling stations around the world. Fuel cell vehicles can pull up, connect a hose, and fill up their tanks just like vehicles using traditional petroleum-based fuels. The heart of a hydrogen dispenser is the point-of-sale flow meter. Meters must be Weights and Measures approved to ensure end customers receive the amount of hydrogen for which they are paying. Sold in mass (kg), Coriolis meters are ideal for the service as they read primarily in mass and have a large measurement turndown capability.
In this challenging measurement application, cars are refuelled with pressures of up to 700 bar and trucks and buses with up to 350 bar at a temperature of -40 °C. Cooling the hydrogen to -40 °C is necessary to keep refuelling times short. A car with a tank capacity of 5 kg can thus be completely refuelled in about 3 minutes. At higher hydrogen temperatures, the excessive heating of the vehicle tank would result in a reduction of the refuelling speed and thus an extension of the refuelling times.
During refuelling, the RHM flow sensor is subject to high pressure and temperature gradients. The required measuring accuracy according to the harmonised standard OIML R139 is an important requirement for the measuring system. Despite the challenging conditions, Rheonik’s Coriolis flowmeters meet the requirements for measuring accuracy and reliability and are approved according to OIML R139 and MI002/OIML R137. In addition, the RHE flow transmitters enable a secure transmission of the measured values directly to the billing system as well as to the control system of the petrol station.
The reliability and performance of Rheonik Coriolis flowmeters in hydrogen applications are guaranteed by the many years of experience gained since the first installation in 1999 – they are also confirmed repeatedly by testimony from our customers across a wide and varied deployment of our measuring systems.
Most hydrogen dispensers around the world are fitted with Rheonik flow meters. Dispenser manufacturers everywhere are confident that when a Rheonik meter is installed, it will provide the performance and reliability that they, their customers and the hydrogen buying public require and demand.
