Gen 5 System

Revolutionary Real-Time Transformer Hydrogen Sensing Now Available


H2scan is now shipping its revolutionary Gen 5 System online hydrogen sensors to provide hydrogen gas concentration sensing in transformer oil for distribution transformers.

The company made waves when it announced the Gen5 System which is three times smaller than existing hydrogen monitoring systems and is based on an application specific integration circuit (ASIC) that delivers very high accuracy sensing at a dramatically reduced price point.

This enables real-time monitoring on lower-cost assets like distribution transformers. The Gen 5 has Modbus over RS-485 communications, has passed shock and vibration testing for traction transformers, operated up to 105°C oil temperature, is IP68 rated and can operate for up to 14 days in 3 meters of water, making it ideal for vault transformer monitoring.

The Gen 5 sensor works with oil immersed transformers and offers real-time, or step-change monitoring to report hydrogen levels as they fluctuate. Its high accuracy sensor head can track hydrogen levels in the transformer oil from 25 ppm to 5,000 ppm. The real time monitoring is ideal for smaller transformers where power overloads can cause higher temperatures which drive up hydrogen levels more quickly. Total install or retrofit time is less than one hour.

The Gen 5 System incorporates H2scan’s patented autocalibration technology. The Gen 5  is calibrated once during production and then needs no maintenance or re-calibration for up to 10 years. H2scan has incorporated every legacy transformer sensor sold with the autocalibration technology and with over 15,000 systems sold worldwide has never had to recalibrate a transformer sensor.

H2scan has transformed its manufacturing to incorporate machine to machine auto calibration. This will allow H2scan to manufacture over 20,000 Gen 5 sensor systems a year.

Bharat Vats, H2scan’s sensor chief growth officer states “With what is happening with COVID 19 around the world, the Gen 5 is a game changer for utilities wanting to eliminate manual sampling and substation visits by its maintenance crew and have real time measurements.” Vats goes on to say, “With the cost of the Gen 5 being several thousands of dollars less than other systems like the Hydran, it’s ideal for utilities to use to retrofit their entire fleet with the Gen 5 DGA system.”

Hydrogen Sensor Saves Oil Refineries $2M


In normal times, real-time hydrogen monitoring can provide insight on hydrogen in up to 20 locations throughout a refinery. This real time data improves process efficiency, catalyst health and provides other benefits that save a lot of money. One example: By just maintaining the correct hydrogen to hydrocarbon ratio in certain processes a refinery can save up to $2 million per year in hydrogen generation and energy costs.

But these are not normal times with Covid-19 still threatening a significant impact on the oil industry. This makes the savings and process automation that comes from real-time hydrogen monitoring even more essential.

H2scan’s Industry Note titled Real Time Hydrogen Monitoring In Oil Refineries Can Save $2 Million Annually details how its H2scan’s HY-OPTIMA™ 2700-series hydrogen specific analyzers can save money by measuring hydrogen in complex gas streams. Click here to download the entire Industry Note.

Oil-Filled Transformer Market is Growing

The Gen 5 is designed for oil-filled transformers, a market that is seeing good growth. According to a report by Global Market Insights, the $33 billion (2017) market is growing by 6% CAGR to $45 billion by 2024. The reason for that growth is the ongoing updating of the aging power grid. See the full report here.

Can California Create a Hydrogen Economy?

California is the most populous state in the US (and home to H2scan), and thus when it wants to encourage a new technology, the ramifications can be felt nationwide. The California Air Resources Board is requiring adoption of zero emission commercial vehicles starting in 2024. These vehicles have been a challenge for battery technology due to “range anxiety.” Hydrogen is perfect alternative. The mandate is driving solutions for generating clean hydrogen and building out a hydrogen distribution network. Read more in this article.

Cool Hydrogen News: A Hydrogen-Powered Flying Taxi

Move over autonomous cars, one company is dusting off the long-held vision of a flying car and using hydrogen to power it. Urban Aeronautics is pushing ahead with its CityHawk electric vertical take-off and landing aircraft and the company has signed a deal with HyPoint to incorporate hydrogen fuel cells into the flying car. The CityHawk has two hydrogen fuel tanks and two fuel cell stacks, which generates the electricity needed to power two electric motors that each produce 939 hp. Read the full story.
