Baker Hughes launches new H2 pressure sensor technology
Baker Hughes has launched its latest Druck H2-rated pressure sensors. Designed to offer longer-term stability and withstand harsh environments, the hydrogen (H2) pressure sensors can be used in various applications, including gas turbines, H2 production electrolysis and H2 filling stations.
Long-term exposure to H2 gas degrades the performance of a pressure sensor, specifically through H2 permeation and embrittlement of the isolation diaphragm, meaning the construction of a H2 sensor is key to maintaining accuracy and stability. Baker Hughes’ latest Druck H2 pressure sensors apply high-performance barrier coating technology to protect the sensor element from the harsh effects of H2, providing customers with a market-leading minimum lifespan of 5 yr across a wide range of pressures.
Teledyne Gas & Flame Detection releases an enhanced version of the GS700-Hydrogen
Whether operating with natural gas, pure H2 or H2 blends, the portable GS700-Hydrogen simplifies gas detection across outdoor and indoor leak detection, purging, barholing and pipeline gas testing applications. The fully ATEX-certified instrument enables utilities to determine the source of gas leaks quickly.
The development of the lightweight (1.4 kg) yet durable GS700-Hydrogen was supported by comprehensive field trials aligned with the H2 transition efforts of prominent UK utility companies SGN and Northern Gas Networks. In Scotland, SGN’s H100 Fife project will establish a green H2 gas network in Levenmouth, Fife.
This pipeline, entirely dedicated to 100% H2, will run parallel to the existing natural gas distribution pipeline, providing customers with a choice between the two gases. SGN collaborated with Teledyne Gas Measurement Instruments, a Teledyne GFD brand, to develop the GS700-Hydrogen. This collaborative process ensured the instrument’s suitability for emergency response and engineering teams, enabling them to precisely detect and locate H2 and natural gas leaks. The collaboration resulted in refining the instrument's operation and validating its technology.
Teledyne GMI subsequently partnered with Northern Gas Networks for the UK’s H21 H2 homes project. Northern Gas Networks adopted the GS700-Hydrogen to ensure safety within its H21 networks and measure H2 during activities like purging and pipeline commissioning.

H2 PRODUCTION
H2U completes performance and durability tests for non-iridium catalysts
H2U Technologies has performed durability tests on new, lower-cost, iridium-free catalyst materials that demonstrate a projected lifetime of 25,000 hr. This durability milestone represents a significant breakthrough and addresses supply chain bottlenecks for sustainable H2 production with proton exchange membrane (PEM) electrolyzers.
Discovering non-iridium catalysts for commercial applications has been challenging, as novel materials often degrade rapidly under the harsh acidic conditions of the oxygen evolution reaction (OER). For perspective, the best iridium-free catalysts known to date offer lifetimes of approximately 1,000 hr—1,400 hr. With a baseline of > 4,000 hr of continuous operation thus far, H2U's iridium-free catalysts, tested at 10x higher current density, demonstrate projected lifetimes of > 25,000 hr. H2U catalysts are projected to last at least 6 yr for targeted applications, such as in PEM electrolyzers paired with curtailed renewables.
As the H2 economy grows and the demand for H2 increases, maintaining catalyst performance without relying on iridium becomes even more critical. Durable catalysts enable the scalability of H2 production and utilization technologies by reducing the frequency of replacements and associated costs. The reliance on iridium has raised industry concerns, as the U.S. Department of Energy has recently categorized iridium as the sole material in the H2 sector at high risk of supply disruptions.
H2U's innovative catalysts are cost-effective and more readily available than iridium. Utilizing these affordable alternatives expands the possibilities for electrolyzer stack design, enabling H2U to explore avenues unrestricted by ultra-thin catalyst layers and low usage of catalysts. This flexibility significantly reduces capital expenses, producing more affordable delivered H2.

Rice University researchers discover method to harvest H2 from plastic waste
H2 is viewed as a promising alternative to fossil fuel, but the methods used to produce it either generate too much carbon dioxide (CO2) or are too expensive. Rice University researchers have found a way to harvest H2 from plastic waste using a low-emissions method that could more than pay for itself.
Green H2—produced using renewable energy sources to split water into its two component elements—costs roughly $5 for just over 2 lb. Though cheaper, most of the nearly 100 MMt of H2 used globally in 2022 was derived from fossil fuels, generating roughly 12 t of CO2 per t of H2.
The researchers exposed plastic waste samples to rapid flash Joule heating for about 4 sec, increasing its temperature to 3,100°K. The process vaporizes the H2 present in plastics, leaving behind graphene—an extremely light, durable material made of a single layer of carbon atoms.

Ionomr has created and is commercializing a new generation of high-performing, environmentally friendly electrochemical materials that are essential building blocks of a green H2 economy.
Working with experts at NREL and Shell and applying industrial and energy agency models, Ionomr has further validated its Aemion+ AEM, providing performance and lifetimes capable of reducing the lifecycle system capital cost of H2 production equipment by water electrolysis by more than 40%. Aemion+ was shown to increase the output of iridium-free electrolysis systems for water electrolysis while repeatedly demonstrating stability from more than 800 hr of tests. It also demonstrated various efficient and stable configurations for directly converting captured CO2 into liquid fuels, improving output three-fold.
Ionomr’s Aemion+ polymers and membranes reduce the cost of green energy because they are designed to eliminate the expensive and scarce components conventionally used for water electrolysis. Materials such as iridium and titanium are replaced with less expensive materials, while performance is enhanced over traditional low-cost alkaline systems and readily pairable with intermittent renewables due to its high ramp rate capability. The membrane technology creates an ultra-stable, lower-cost, safer and more flexible system.
Ionomr’s membranes and polymers are synthesized from an environmentally friendly hydrocarbon base, using a fraction of the energy in their production. They demonstrate no bioaccumulative tendencies and are non-toxic to the environment through production, use and end-of-life. They present the ideal replacements for conventional membrane and polymer products, all containing per- and poly-fluoroalkyl substances.
