In some instances, systems and instruments that come into contact with hydrogen must withstand extraordinarily high pressures and low temperatures and cover corresponding measurement ranges. The qualitative measurement of the H2 as a byproduct of the electrolyzer also places special demands on the instrumentation. With the OXY5500 oxygen analyzer, Endress+Hauser offers a reliable method of determining the amount of residual oxygen in hydrogen in real time. In addition, the J22 TDLAS gas analyzer (tunable diode laser absorption spectroscopy) can measure traces of moisture in burnable gases in real time, which also gives an indication of the quality and calorific value of gases.

Blending H2 in fuel gases to reduce emissions

Even if it were already technologically feasible to partially or completely convert plants to hydrogen today, it’s worth pointing out that the industry finds itself in a phase in which hydrogen is still not available in sufficient quantities, to say nothing of the aforementioned green hydrogen from renewable sources. Nonetheless, even if the conversion to H2 cannot be carried out immediately and completely in one fell swoop, emissions can be partially reduced by blending H2 with other fuels. Considering that the precise composition of the gas has to be measured, the instrumentation plays a crucial role here. Let’s take a look at a gas turbine fed by a hydrogen blend as an example. In this scenario, flow measurement and optical analysis technology from Endress+Hauser can be used to determine the natural gas and H2 mixture and retrofit the plant step-by-step for pure hydrogen operation. Another application that follows this approach is the use of a hydrogen blend to fuel hot blast furnaces, which is also known as green steel.

CO2 as a raw material: active capture emission technologies

For processes that have not yet been converted to renewable energies, or for those in which conversion is not possible, the third point of this article offers a solution: active carbon capture technologies (CC). This approach captures the CO2 before it’s released into the atmosphere where it has a harmful impact on our climate. Direct air capture (DAC) captures CO2 directly in the surrounding air. This involves processes such as amine scrubbing, which are already frequently used to capture CO2 from process gases, exhausts or from natural ventilation.

To precisely measure the concentration of CO2 in the outlet gases, Endress+Hauser relies on proven tunable diode laser absorption spectroscopy (TDLAS) technology to ensure that the process can be reliably and efficiently controlled. One example in which CC is already being used is the cement industry. Although CO2 cannot be completely avoided in this environment, it’s nevertheless captured through CC technology and other measures. While these measures help prevent further CO2 from being released into the atmosphere, active capture devices can also be used to filter CO2 from the surrounding air through the use of renewable energy

CO2 as a source material for derivative products

Although the focus of the CO2 transformation is on avoidance and capture, carbon dioxide plays an impor- tant role in industry as a raw material in production. To cite one example, CO2 is used in greenhouses to increase the rate of photosynthesis and stimulate plant growth, which then boosts harvest yields with the same sized area. Even in the food industry, CO2 is required for more than just carbonating beverages and is also used by beer breweries during the bottling process. CO2 is also used as a raw material in the chemical industry, where it will be lacking if processes are converted over to zero-emission energy sources and no replacement is created. This impacts the production of methanol as an example. As absurd as it initially sounds, a new CO2 supply infrastructure, such as a pipeline network, might even be necessary in this case. For every one of these storage, transport and input processes, plant operators will need precise measurement data for process control, monitoring and documentation, for which Endress+Hauser offers various instruments, solutions and services.

Full-scale measurement concept for the energy transformation

A successful CO2 transformation will require a combination of numerous measures and various technology approaches. Endress+Hauser offers a broad spectrum of instruments and solutions for managing the process of converting the chemical industry to zero-emission technologies. These include instruments designed especially for hydrogen applications that take into account the material properties of the molecules or extreme process conditions. Endress+Hauser is also setting benchmarks in the field of optical gas analysis with TDLAS, QF and Raman sensors that help users precisely determine the composition of gases, liquids and solids. l
