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.

Renewable Energy Use Cases

Our moment and temperature compensated LowProfile load cells use proprietary alloy strain gages to provide the most accurate readings possible in the harshest environments, such as wind turbines. Interface has a special line of intrinsically safe solutions for harsh environments.

Our LowProfile load cells with loop-powered intrinsically safe amplified output are designed for use in hazardous locations. These load cells are specifically designed from Interface models by adding high resistance strain gages for low-current loop power and shielded internal amplifier for extra low emissions and minimal EMI susceptibility.

Interface’s S-Type Load Cell series provides a suitable force measurement sensor for applications in heavy industries where explosive dust and environment conditions. Our miniature load cells are found to measure alternate energy testing, such as hydropower equipment and solar testing.

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.
