H₂ EQUIPMENT 

H2scan launches HyView Display to advance transformer and battery room H₂ safety solutions

H2scan has launched HyView, an industrialized display to complement its Gen 5 sensor products to meet a broad range of applications. HyView is a hardened display that can consolidate data from multiple hydrogen (H₂) sensors and is available in explosion-proof and National Electrical Manufacturer Association (NEMA) ratings. 

HyView pairs with H2scan’s next-generation sensing technology to provide local indication of H₂ and oil temperature data in transformer applications and H₂ concentration levels in area monitoring applications. The product includes an alarm output, which allows customers to easily wire alarms into their supervisory control and data acquisition systems, data center infrastructure management systems, network operations centers and other monitoring systems that accept digital outputs. HyView connects with up to four GRIDSCAN 5000 or HY-ALERTA 5021 sensors and enables indicating and alarming for real-time monitoring. 

HyView includes a dual-line display easily scaled for 4-20 mA analog output values, and its wide viewing angle display and through-glass buttons create a simple and convenient user experience. These buttons allow the HyView to be programmed and operated through the front panel, thus eliminating the need to remove the cover in hazardous areas. 

Battery room operations are made safer by the HyView product when combined with H2scan’s HY-ALERTA 5021 H₂ area monitor. HY-ALERTA meets all code requirements, including continuous monitoring to keep H₂ below a 25% lower flammable limit, communications to activate exhaust fans and Modbus communication to meet annunciation requirements. 

The GRIDCAN 5000 and HY-ALERTA 5021 sensors eliminate false positives by detecting only H₂. The sensor lifecycle is 10 yr−15 yr (avoiding expensive replacement costs) and auto-calibrates, reducing maintenance costs. 

Evonik starts up new production plant for H₂ extraction in Austria 

Evonik has started a new hollow-fiber spinning plant to produce gas separation membranes in Schörfling am Attersee in Austria. The new production capacity enables the company to meet ongoing strong demand for SEPURAN membranes in biogas, nitrogen, H₂ and natural gas applications. Evonik has invested a low double-digit €MM amount in the new plant and created around 30 new jobs in Schörfling. 

In the new production plant, several steps process a high-performance polymer into fine hollow fibers that are at the heart of Evonik’s SEPURAN membrane technology. The specialty chemicals company draws on its many years of expertise in polymer chemistry and adjusts key membrane properties already at the development stage of the base material—a high-performance polymer—to produce particularly selective and robust membranes that can withstand extreme pressures and temperatures. 

Evonik already relies entirely on renewable energies for membrane production in Schörfling am Attersee. Green electricity from wind, water and biomass has been a key energy source for the production facility for years. Since the beginning of 2022, the specialty chemicals company has met 100% of its gas requirements with biomethane from regional production. By switching to an environmentally friendly energy supply, Evonik is reducing its direct CO₂ emissions in Austria by approximately 4,000 metric tpy. 

SEPURAN Noble membranes extract the H₂ transported through natural gas pipelines from the methane/H₂ gas mixture at specific H₂ gas withdrawal points. SEPURAN NG membranes enable efficient natural gas processing from sources with high CO₂ concentrations. SEPURAN Green membranes enable efficient biogas processing from organic and circular sources. 

H₂ PRODUCTION 

Sunfire successfully commissions high-temperature electrolyzer 

Renewable fuels and chemical products produced from renewable electricity and CO₂ are considered promising climate-neutral solutions for the chemical and mobility industries. The Dresden-based H₂ company, Sunfire, has developed a new co-electrolysis technology to produce these raw materials. 

Sunfire’s high-temperature co-electrolysis plant is an important part of the research project in its second funding phase. The company’s plant factory acceptance test has been completed. 

As a result, Sunfire put its new generation of co-electrolysis into operation for the first time. The unique feature of this technology is the process in which synthesis gas—a mixture of H₂ and carbon monoxide—is produced in one step using renewable electricity from water, steam and CO₂. The whole process takes place at high operating temperatures of up to 850°C. 

Within the final acceptance test, an output of up to 220 kW with an electrical efficiency of more than 85% low heating value was achieved, representing a significant increase compared to the proof-of-concept system of the first project phase (10 kW). Sunfire relied on significant operational experience from the completed SynLink research project funded by the German Federal Ministry of Economics and Climate Protection. Sunfire developed and validated a co-electrolysis module in the 150-kW size class as part of the project. 

LONGi Hydrogen launches new generation of alkaline electrolyzer 

LONGi Hydrogen, a wholly-owned subsidiary of China's solar giant LONGi Green Energy Technology, has launched its new generation of alkaline electrolyzed water H₂ production equipment, ALK Hi1, in Beijing, continuously exploring the lowest of energy consumption and redefining the height of energy efficiency. 

Based on the rich experience in the photovoltaic field, LONGi found that—like the levelized cost of photovoltaic energy—the core path is to reduce the electricity consumption of H₂ production units for the same electricity consumption to produce more H₂. The lower the levelized cost of H₂ (LCOH) is, the more cost-efficient the green H₂. 

Electricity price and energy consumption per unit of H₂ production are the two variables that contribute to the highest sensitivity of LCOH. The full-load direct current (DC) power consumption of ALK Hi1 can be as low as 4.3 kWh/Nm³. It is even lower for ALK Hi1 Plus, down to 4.1 kWh/Nm³, to adapt to H₂ production scenarios demanding higher utilization hours. It even hits 4.0 kWh/Nm³ when the current density is 2500 A/m². 

Research also shows that full-load DC power consumption of the global electrolyzed water H₂ production industry—alkaline water H₂ production technology and proton exchange membrane electrolysis—is in the range of 4.5-4.6 kWh/Nm³. 

So far, LONGi ALK Hi1 series products have passed empirical testing, and its performance has been certified by third-party authorities, such as Det Norske Veritas and DEKRA Testing and Certification, and measured following the national standard of GB-32311-2015. LONGi ALK Hi1 series products are rated to have the level 1 energy efficiency of H₂ production system. 

LONGi ALK Hi1 series products have the characteristics of high efficiency and high production capacity, which means a reduction of DC power consumption by more than 10%, and the LCOH of H₂ production in different scenarios will be greatly cut down. For 0.1 kWh/Nm³'s reduction in H₂ production DC power consumption, depending on the number of system utilization hours, H₂ LCOH can be reduced by 1.8%−2.2%, equivalent to a reduction of the initial investment of H₂ production equipment by 10%–25%. In the context of carbon peaking and neutrality, the energy development trend will gradually shift from carbon-based to silicon-based energy and then to H₂ energy. 

H₂ APPLICATIONS INNOVATIONS 

INEOS plans low-carbon H₂-powered cracker in Europe 

INEOS Olefins Belgium’s new cracker in Antwerp will have the lowest carbon footprint of all European crackers, five times better than the worst in Europe and two times better than the best, according to the company. The plant is designed to use low-carbon H₂, and the cracker will have a zero-carbon footprint as soon as enough H₂ becomes available. 

INEOS has raised €3.5 B to support the construction and operation of the cracker, and this is the largest investment in the European chemical sector for a generation. The plant can also operate entirely with low-carbon H₂ and has room for a carbon capture facility and future electric furnaces. 

Supported by 21 commercial banks, the deal validates the strong commercial rationale of the project and its leading environmental characteristics. The debt will be drawn in stages to support the spending profile of the project through to completion. 

The cracker will produce ethylene, a vital raw material for a wide range of products essential to daily lives, from insulation to lightweight vehicles, plastics for medical, healthcare and food hygiene, and technology for renewable energy. 

H₂ STORAGE AND TRANSPORTATION APPLICATIONS 

Calvera Hydrogen develops H₂ transport tube trailer model for Shell Hydrogen

Calvera Hydrogen has developed a H₂ tube trailer model at its facilities in Zaragoza, Spain. The equipment is designed to transport 1 t (2,270 lb) of H₂ on U.S. roads and more than 1.3 t (2,870 lb) on EU roads (due to the different road weight regulations of each region), with a working pressure of 517 bar (7,500 psi). This makes it the highest-operating pressure tube trailer in the international market. It is made of state-of-the-art carbon fiber and is 45-ft long. This project has been developed for Shell Hydrogen and will be used to service Shell’s H₂ refueling stations globally. 

The companies have been working together for more than 2 yr on this project's engineering and technological development, which will take its first steps in the U.S. and Germany. Due to a framework agreement between the two companies, new units of this tube trailer model are being developed to cover the H₂ transport needs of Shell’s refueling stations in the U.S., Europe and the UK. 

The equipment is designed to optimize the capacity and pressure of the stored H₂ and achieve maximum efficiency and cost savings in the dispatch of H₂ in the H₂ refueling stations. The tube trailer actuates through automatic valves at different pressure stages and performs the dual function of mobile and fixed smart storage. 

This project stands out for the innovation and complexity of its design and has been conceived under the highest safety standards. It has a differential feature that makes it unique since it is approved to comply with regulations in the U.S. and Europe, which has been a challenge in the design and regulatory processes for its approval.
