Here is a quick excerpt from the article, Force sensing helps hydrogen electrolyzers efficiently harness energy.

The use of hydrogen as a clean and reliable renewable energy source has been a carrot on a stick for green energy innovators for many, many years. Scientists and technologists have understood the positive impact of hydrogen for a long time, and even harnessed it at times, but the ability to reliably store and harness this energy at a reasonable cost has previously eluded them. However, hydrogen is back in full force as storage and battery technology has advanced, giving new life to the promise of hydrogen.

Hydrogen is critical to the future of green energy because it is an optimal solution to storing renewable energy from other sources such as wind and water. In certain areas, like California, we’re actually producing too much energy from renewable sources, but have no place to store. This is leading to a tremendous amount of resource loss. Therefore, hydrogen innovation has come back to become a storage solution to curtail waste and hold enough energy to power more infrastructure with green energy.

Interface Solutions for Growing Green Energy Case Study

Interface provides the industry’s most accurate and reliable force sensors, and we have been working with organizations in the energy industry, both traditional and alternative. We understand the unique requirements of green energy and have developed a widening line of products uniquely suited for these innovations.

We have recently worked with multiple types of components for electric vehicles including batteries, engines and more, as well as with alternative energy sources like wind, solar, and hydrogen power. Interface brings the accuracy and reliability, in addition to having an expert engineering team that can quickly develop customized solutions.

Interface solutions are cost effective and can often end up saving critical dollars overall. Take for example a recent case study we developed in which we outlined our role in harnessing hydrogen power using an electrolyzer. In this case, force sensors were used to significantly reduce downtown by creating an automated monitoring system that replaced regularly scheduled maintenance that was often unneeded but caused downtimes. And with that process came significant losses in energy and money. Interface helped to create an autonomous monitoring system that reduced downtime and estimated the customer would break even on their investment on the force monitoring system in one year.

Interface Supports Renewable Energy Innovation

Interface is a core test and measurement solutions partner to some of the largest energy production and equipment manufacturers in the world. We continue to provide sensor devices and instrumentation, including custom designed OEM solutions, for a range of energy applications used above ground, below ground and at sea.

As expansion of green and clean energy innovation rapidly grows, Interface finds our precision force and torque measurement products in high demand to use in producing new energy from wind, solar, hydrogen, geothermal, biomass and biofuels. If it is designed to create sustainable power, chances are Interface products play a part in the test, management, and monitoring of equipment used for renewable energy production.

The test and measurement sensors and instrumentation devices our energy sector customers use must be durable, high quality, rugged and provide the most accurate results possible even in harsh environments. If the equipment fails, our customers risk steep losses from lack of products, and potential exposure to safety hazards.

A renewable sources application that we are incredibly excited about for the ability to put our innovation to work and make an impact in the mass production, is in the production of hydrogen energy. Hydrogen fuel cells have been around for a long time; however, recent advancements in how we harness the power of hydrogen have led to a renaissance in its use. Interface has had the opportunity to provide robust and accurate products used to evaluate some of the infrastructure being built to harness this renewable power source.


Electrolyzer and Fuel Cell Tie Rod Monitoring for Hydrogen Production

Converting to renewable energy is one of the primary tools to address growing energy consumption, as well as addressing climate change. Storage of energy is critical to make renewables work, and hydrogen, or its derivatives are a promising way to store power. Electrolyzers convert power to hydrogen, and fuel cells convert the hydrogen back to electricity. They are both made by stacking multiple anode and cathode plates and a membrane between each, and tie-rods hold them in place.

A real-time fuel cell monitoring system needs to measure the tension of the tie rods to avoid costly preventive and unplanned maintenance shutdowns. Interface suggested installing LWHP Precision Load Washer Load Cells connected to WTS-AM-1E Wireless Strain Bridge Transmitter Modules, under the bolts of the tightened tie rods. The WTS-AM-1E’s were encased in a junction box enclosure. The LWHP’s measured the tension between the plates from the tie rods, and the real-time results were transmitted wirelessly from the WTS-AM-1E’s to the WTS-BS-6 Wireless Telemetry Dongle Base Station when connected to the customer’s computer. Interface’s load cell system successfully monitors the tie-rods tension in real time, thus preventing unnecessary costly preventive maintenance and unplanned shutdowns of the electrolyzer. This hydrogen fuel cell electrolyzer application note shows Interface base products. The actual application used customized column load cells and instrumentation.

Windmill Energy Blade Measuring

A customer wanted to improve the performance of a windmill by adjusting the blade pitch and measuring the torque generated as power ramps. Interface offered its T2 Ultra Precision Shaft Style Rotary Torque Transducer, which is coupled between windmill blade propeller and electric generator. Test torque data is logged into the customer’s data acquisition system (DAQ). Using this solution, the customer was able to use torque data to determine the optimal blade pitch for the windmill. The windmill will now generate more power and with less stress on the bearings. Read about this use case here.


Wave Energy Generator

A scientist sought to create electricity by using the energy that is generated by ocean waves and Interface was able to help provide an important sensor for the generator. As electricity is generated by ocean waves, an Interface load cell can measure tether line tension using a submersible 3200 Hermetically Sealed LowProfile® Precision Stainless Load Cell or ITCA Tension and Compression Load Cell. The mooring line was attached to the load cell base and the platform generator was connected to the load cell hub. This measured the forces that were generated by the ocean waves and data was later analyzed by the customer’s data acquisition system (DAQ). The scientist was able to use force data to adjust the tether line. Also, if tether line breaks free, the scientist is alerted immediately to reattach the tether line. Read more here.
