Power plants: hydrogen in power generation
How to reach decarbonization goals in line with the growing demand for energy
Hydrogen's potential as a fuel source is unparalleled: Its combustion releases intense heat with no CO2 emissions. Additionally, hydrogen is used in fuel cells generating electricity through a clean chemical reaction emitting only water vapor as a by-product. This makes hydrogen a game-changer for clean and sustainable energy solutions, especially if produced with electricity from renewables (green hydrogen). However, the requirements for the measurement devices to be used are challenging.

Hydrogen blending for natural gas-fired turbines
Energy companies that produce, process, transport and distribute natural gas are now working towards a future with hydrogen as a significant part of the energy mix. When using renewable energy sources for low-emission power generation, hydrogen can be an alternative or addition to conventional fuels for gas turbines. In the coming years and decades, natural gas will be mixed with hydrogen in increasing concentrations.
Our expertise in the field
With the help of process measurement solutions from Endress+Hauser, a new Long Ridge Energy (LRE) power plant is successfully showcasing the viability of clean hydrogen in power generation. The facility was fitted with Coriolis flow meters and a Raman Rxn5 analyzer to measure and validate the H2 injection rate and the quality of the blend. Reliable, nearly instantaneous feedback about the integrity of the gas blend helps to prevent hydrogen overshoot, which could damage the combustion system.
- Raman Rxn5 analyzer delivers real-time, reliable composition analysis of rapidly changing gas turbine fuels blended with hydrogen
- Coriolis mass flow meters are capable of multivariable measurement in gas streams, providing excellent accuracy of mass and corrected volume of hydrogen and natural gas including world-wide accepted custody transfer approvals
- EPA compliance (40 CFR Part 75) using reliable fuel flow meters

Ensuring hydrogen quality for use in fuel cells
To ensure the reliable and efficient operation of fuel cells, high-purity hydrogen is crucial. This typically involves removing impurities to levels that meet specific standards, such as those set by organizations like the International Organization for Standardization (ISO). Producing and delivering high-quality hydrogen is critical for the successful implementation of fuel cell technology in various applications, including transportation and stationary power generation.
Our expertise in the field
By using Endress+Hauser Coriolis flowmeters, you safely measure and control the flow of hydrogen. Optical analysis gas analyzers detect the presence of impurities such as moisture (H2O) and oxygen (O2) down to part-per-million levels. The non-contact measurement technology provides reliable, maintenance-free operation to ensure that hydrogen meets quality standards.

Green hydrogen via electrolysis: ensuring water quality
One of the most critical steps for electrolysis is the water preparation to a particular quality specification, which varies for different types of electrolyzer technology. It is essential to measure the following parameters: level, flow, pressure, conductivity, and in some cases pH. As green hydrogen facilities scale up, TOC may be another parameter to quickly detect failures in upstream treatment that would not be caught by conductivity or pH.
