FBAR Hydrogen Sensors

By 2040, it is estimated that the world will be using nearly 100 million tonnes of hydrogen every year. 

Hydrogen fuel has risen in popularity as a replacement for harmful fossil fuels, the intention being to de-carbonise manufacturing processes, transport systems and provide clean power. Currently, there are multiple key hydrogen development areas both in Great Britain and Europe, where hydrogen linked technologies are trialedtested and bought to market. A highly publicised example of this would be Hydrogen Valley situated in Denmark, part funded by the EU, this hub for hydrogen linked companies will aim to power the countries energy and transport sectors with only renewable energy by 2050.  

Transport systems are the biggest development area for hydrogen technologies, particularly fuel cells, where hydrogen is reacted with oxygen to drive motorsThe use of hydrogen has been tested across all types of vehicle and in multiple use cases; including aviation, marine and automotive in logistics, transport and sport applications.  

The first mass produced hydrogen car was made available to certain regions in 2013 by Hyundai and had a range of around 600KM, far exceeding the standard for electric cars. Since 2013, many of the major car manufacturers have followed the trend towards the hydrogen economy and followed with research and the development of production groups.  

The rapid expansion of hydrogen technologies entering the market will drive demand for multiple supporting technologies, such as sensors and packaging 

Why are hydrogen sensors so important?  

Hydrogen has the highest flammability range and the lowest required ignition energy of any fuel, meaning that the control and treatment of hydrogen is very important. Furthermore, because hydrogen is the smallest molecule it leaks very easilygiven its colourless, odourless and tasteless properties it is undetectable by humans and so is reliant on sensors to detect it.  

Hydrogen’s use as a fuel has been validated by multiple official laboratories and so when treated properly is a more effective and less dangerous than current liquid fuels.

To meet the demand of the ‘Hydrogen Economy’, Worcester Scientific have developed an FBAR hydrogen sensor. The benefits of exploiting FBARs for hydrogen sensing is the sensitivity to measure hydrogen just above background levels, embedding the sensors into systems for critical leak detection and cost effectively monitoring processes within hydrogen production/use.
