In addition to renewable energy production, the constant availability of energy and the matching of supply and demand is a hot topic. In all these cases storage is needed in a fossil-free energy system. Hydrogen's significance as an energy carrier during this transformative phase cannot be overstated. Presently, green hydrogen is garnering unprecedented attention. Our portfolio of flow meters and flow controllers finds versatile applications within numerous hydrogen applications. This encompasses direct hydrogen flow control and pressure measurement, as well as within the broader spectrum of systems and processes connected to hydrogen. These applications require reliability, safety, precision, and usability across a diverse range of flow capacities.
In the field of green hydrogen production, the enlargement of electrolyzer capacity is resulting in larger stack sizes. Consequently, the demand arises for hydrogen flow measurement that entails minimal pressure drop, accommodating line pressures in the range of 30 bar. Notably, this must be accompanied by stringent safety standards and a high degree of accuracy.
There are many ways to store hydrogen, leveraging its high energy density despite its light weight (approx. 1/12th that of air). Efficient storage and distribution require compression or conversion to boost energy density per volume—examples include: compression, liquid carriers (ammonia, ethanol), Liquid Organic Carriers (LOHCs), and Metal Hydrides. Bronkhorst is actively engaged in projects for effective hydrogen-carrier binding and subsequent release post-transport. This involves research projects to develop inexpensive stable and highly effective catalysts with the minimum use of rare earth metals.
In the transition toward renewable energy, hydrogen's utilization has made significant steps, particularly in green hydrogen production. Two key applications stand out: the direct combustion of hydrogen, either in its pure form or as a blend with natural gas, and electricity generation through fuel cells via catalytic reactions. A noticeable trend is the adaptation of industrial furnace burners to accommodate hydrogen or hydrogen-gas blends, aiming to reduce carbon emissions. Bronkhorst provides tailored solutions for optimal burner control, e.g. in manifold systems with ratio control of fuel and oxygen. Fuel cells are used in both automotive and stationary applications. Despite their growing commercial availability, ongoing research is essential to enhance aspects like efficiency, cost, leak prevention, and diffusion reduction. Bronkhorst instruments contribute to research setups and test benches for fuel cell stacks and engines.
