Hydrogen sensor for safe production passes two thousand hours in test

A newly developed hydrogen sensor from SulfiLogger A/S has surpassed two thousand hours of testing in an electrolysis plant from Green Hydrogen Systems. This milestone was reached in collaboration with several innovative partners from the Danish value chain for Power-to-X, aiming to ensure the safe and cost-effective production of green hydrogen.

Cost-effective, safe, and stable operation of facilities for green hydrogen production is a crucial piece in the puzzle of green transition. Therefore, the partners in the SafePtX project, supported by the Danish Energy Technology Development and Demonstration Program (EUDP), have chosen to collaborate on a new sensor for monitoring gas concentrations that arise in the electrolysis plants, which are pivotal for the future of green hydrogen production.

The sensor in the project was developed by the Danish, Aarhus-based technology company SulfiLogger A/S and has been tested in one of the hydrogen production facilities developed and produced by the Danish company Green Hydrogen Systems.

The test has just reached an important milestone – two thousand hours in test operation – reports Søren Porsgaard, CEO of SulfiLogger A/S.

“The many hours of testing show that the sensor from the project has an exceptional robustness in a harsh environment – and it makes monitoring simpler than today. Safety is crucial in the production of green hydrogen, and our sensor can be installed directly in the electrolysis plant. This will increase confidence in the systems, improve monitoring and maintenance possibilities, and ultimately ensure a cheaper price on the green hydrogen to the benefit of the consumers,” says Søren Porsgaard.

Affordable, green hydrogen

At Green Hydrogen Systems, the positive test results from the innovation project SafePtX help to ensure that the company’s facilities can deliver even more green hydrogen at a lower price.

“Our goal is for our facilities to produce as much green hydrogen as possible from renewable energy sources. This must be done with a focus on safety, price, and quality. Therefore, it is extremely positive to see that the sensor works as expected. It ensures that we spend less time on calibration and thus more time on the production of green hydrogen, for example, for the production of green fuels,” says Christian Buhl Sørensen, R&D Manager at Green Hydrogen Systems.

An emission-free future

Following the successful test phase in Green Hydrogen Systems’ facility, the partners in SafePTX are working on the final details needed to market the sensor in Denmark and globally.

“The market for green hydrogen production will be enormous on a global scale – all projections show this – and our sensor can help support faster and better electrolysis production, which is part of the solution on the road to an emission-free future,” says Søren Porsgaard, who has also collaborated with the technical partners Danish Gas Technology Centre and the Danish Institute of Fire and Security Technology in the innovation project.

Denmark’s national energy cluster, Energy Cluster Denmark, facilitates the project, which concluded at the end of 2023.

“SafePtX is an example of the benefits of collaborating on innovation in Denmark. The partners improve existing products on the market and have also developed a sensor that can be sold globally, accelerating the development of Power-to-X. We need to produce green hydrogen in a capacity of many hundred gigawatts alone towards 2030 for the benefit of the climate, and Danish companies can create growth and jobs along the way for the benefit of us all. SafePtX is one of several good examples of this,” says Glenda Napier, CEO of Energy Cluster Denmark.

The innovation project SafePTX was supported by the Danish Energy Technology Development and Demonstration Program (EUDP) with DKK 5.24 million. The project started in January 2022 and concluded at the end of 2023.

The partners are: Green Hydrogen Systems, SulfiLogger, Danish Gas Technology Centre, the Danish Institute of Fire and Security Technology, and Energy Cluster Denmark.
