SYDNEY, -- Siltrax, a pioneering company in fuel-cell innovation, today announced it has achieved the highest recorded volumetric and gravimetric power densities for hydrogen fuel cells.

Independent third-party testing conducted by TÜV Rheinland validated Siltrax’s proprietary 150kW G-100 Fuel Cell, which delivered 9.77 kW/L volumetric and 9.7 kW/kg gravimetric power density, surpassing known industry records.

 

This breakthrough enables the development of lighter, more compact and more efficient fuel cells poised to accelerate the decarbonization of industries where space and weight are critical, such as electric aircraft, heavy-duty trucks and shipping.

At the core of the achievement is Siltrax’s patented silicon-based fuel cell architecture. By integrating a world-first silicon bipolar plate (Si-BPP) and a micro-flow channel design, previously unachievable with conventional materials, Siltrax enables higher power output from fewer materials. This represents a crucial step toward scaling fuel-cell adoption in weight- and space-constrained markets.

“Our latest results showed a 30% performance gain over the best industry benchmarks, underscoring the extreme benefits of our silicon BPP and micro-channel designs,” said Dr. Zhengrong Shi, founder of Siltrax. “This breakthrough translates directly into more power-dense, more reliable and more cost-effective fuel cells by extracting more power from fewer materials.”

This performance milestone underscores the strength of the company’s core innovation: its proprietary bipolar plate and precision-engineered flow channels. Notably, the achievement was made using only commercially available components—highlighting the significant untapped potential still ahead.

“What’s especially exciting is that this high-efficiency result was achieved solely through the optimization of our proprietary bipolar plate and flow channel design, while all other components were off-the-shelf from commercial suppliers,” said Dr. Zhengrong Shi. “These numbers represent just the beginning—by integrating customized gas diffusion layers and membranes tailored to our high-precision architecture, we see significant additional performance gains on the horizon,” said Daniel Zafir, Director of Global Partnerships at Siltrax.

Power Density that Unlocks New Markets

While traditional hydrogen fuel cell systems often fall short of the performance required for demanding applications, Siltrax’s G-100 sets a new benchmark. The results not only exceed long-term international performance targets but also redefine what’s possible in next-generation zero-emission mobility and power systems. For example, the G-100’s 9.7 kW/L volumetric density and 9.7 kW/kg gravimetric power density exceeds Japan's NEDO Organization’s targets for volumetric power density, 6.76 kW/L (2030), 8.42 kW/L (2035), 10.38 kW/L (2040) and those of the U.S. Department of Energy’s USDRIVE program for stack specific power: 2,000 W/kg (status), 2,700 W/kg (2025 Target).

By surpassing power density milestones others are still striving to reach, the G-100 is poised to accelerate commercial adoption across industries where every kilogram and cubic centimeter counts. As industries seek cleaner alternatives to fossil fuels, compact and powerful fuel cells, such as the G-100, offer a viable path forward.

Enabling the Future of Zero-Emission Power

With this record-setting performance, Siltrax is expanding the boundaries of what’s possible in applications where traditional stacks face critical limitations:

  • Aerospace & eVTOLs (electric vertical takeoff and landing aircraft): High power-to-weight ratios enable extended ranges and increased payload capabilities for increased investment returns.
  • Maritime and Drones: Durable, compact solutions are ideal for extended operation in space-limited environments.
  • Heavy-Duty Transportation: High-density propulsion systems facilitate the electrification of heavy transportation, maximizing cargo capacity and refueling efficiency.

The G-100 milestone builds on Siltrax’s previously announced silicon fuel cell platform, developed with support from the Clean Energy Finance Corporation (CEFC) and Virescent Ventures. By leveraging mature photovoltaic industry supply chains and high-throughput silicon fabrication methods, Siltrax’s approach also holds the potential to significantly reduce the cost of advanced fuel cells.

Recently, Suzhou Zhiqing Bocai Technology Co., Ltd., a domestic AEM anion exchange membrane R&D manufacturer, has completed the delivery of an order for an anion exchange membrane with a width of 65cm and a thickness of 60μm after a 9-month pre-product verification cycle, which will be applied to the megawatt hydrogen production project of an electrolyzer company. This delivery marks that Zhiqing Bocai has the full-scale membrane production capacity covering mainstream electrolyzer models, and verifies the technical advantages of the whole chain from material formulation design to product scale-up production.

 

(Figure: 65 cm wide and 60 μm thick anion membrane delivered by Zhiqing Bocai)

 

In the industrial changes of accelerating the iteration of new energy material technology innovation, Suzhou Zhiqing Bocai Technology Co., Ltd. is becoming a key promoter of the localization process of green hydrogen core materials with a full range of AEM anion exchange membrane product systems. The company has achieved an industrial production capacity of 20-100μm thickness and 80cm ultra-wide width, and can stably deliver differentiated product matrices such as homogeneous membranes, reinforced membranes, and hydrogen depletion membranes to meet the strict needs of high-performance membrane materials in scenarios such as electrolyzers and flow batteries.

 

Dr. Peng Hanqing, co-founder and general manager of the company, is one of the few expert entrepreneurs in China who has been deeply engaged in the research and development of anion exchange membrane materials for more than ten years, graduated from Wuhan University with a major in physical chemistry, and studied under Professor Zhuang Lin, a distinguished professor of Changjiang Scholars. Professor Sun Wenbin, co-founder and chief scientist of the company, is currently the director of the Department of Applied Chemistry of the School of Chemistry, Chemical Engineering and Materials of Heilongjiang University, the reserve leader of organic chemistry, and a member of the Key Laboratory of Functional Inorganic Materials Chemistry of the Ministry of Education. With 18 years of experience in organic chemistry/polymer research and industrialization, he is mainly engaged in the design and synthesis of organic molecules and the research of organic membrane functional materials, and is currently fully responsible for the research and development and innovation of the company's new generation products.

 

Thanks to the team's years of scientific research accumulation and perfect engineering system, Zhiqing Bocai's products have shown significant advantages in performance. The AEM series products independently developed by the company, based on the original high-efficiency polymer synthesis process and modification scheme, have achieved breakthroughs in key performance indicators: tensile strength up to 50MPa, swelling rate controlled within 8%, ionic conductivity of more than 150mS/cm. At present, the product has passed the performance verification of many leading electrolyzer companies and obtained purchase orders, and the upgraded AEM reinforced membrane and AEM hydrogen depletion membrane are also being sent to many customers one after another, entering the testing and import stage.

On the manufacturing side, Zhiqing Bocai has completed its own resin and membrane solution production line, with a total area of 1,000 square meters, which can achieve the stable production of anion exchange resin with an annual production capacity of 2 tons, and at the same time, with the help of a mature cast production line of strategic partners, it can achieve a stable supply of anion exchange membrane with an annual production capacity of 25,000 square meters.

 

(Figure: Site map of Zhiqing Bocai resin and membrane solution production line)

 

While steadily promoting the implementation of core products, Zhiqing Bocai is also actively planning the layout of cutting-edge technologies. The company has completed the industrialization R&D layout of a number of main chain structures, covering a new "rigid chain" structure and a "flexible chain" structure of anion exchange membrane series, forming a multi-level product system covering different working conditions and performance requirements, and further building core competitive barriers. Especially in the field of flow batteries, the company is working with strategic partners to jointly develop special anion exchange membranes for flow batteries, and significantly improve the electrochemical performance and cycle life of the membrane through special structural design and thickness optimization according to the needs of energy storage scenarios, so as to seize the opportunity of the trillion-level energy storage market in the future.

 

Dr. Peng believes that the cost and durability of AEM anion-exchange membranes will be the two most important indicators in the future AEM anion-exchange membrane market. At present, the mainstream AEM structure in the market must not be the ultimate solution in terms of stability, and Zhiqing Bocai has been determined to explore new AEM structure design since the establishment of the company. At present, the company's three Ph.D. teams are steadily advancing on their respective technical routes, aiming to increase the AEM lifetime to 50,000 hours and reduce the cost to one-third of that of international peers, helping Chinese downstream enterprises reduce costs, enhance competitiveness, and accelerate the overall mature and reliable development of the AEM industry.

A green hydrogen facility in Uzbekistan, developed in partnership by ACWA Power, PowerChina Huadong Engineering Corporation, and LONGi Hydrogen, has begun producing hydrogen as it prepares for full commissioning.
LONGi Hydrogen supplied four 1000 Nm³/h alkaline electrolyzers, along with associated systems including power supply, control units, gas–liquid separation, and purification equipment. The systems were delivered in accordance with international standards, including relevant EU directives and U.S. industrial codes.

As of late June, all four electrolyzers had undergone energization, current ramp-up, gas separation and purity checks, venting trials, and emergency shutdown drills. Initial results indicate stable operation and production of high-purity hydrogen and oxygen. Full commissioning is expected to follow.

The project is powered by 52 MW of wind energy and is designed to produce approximately 3,000 tonnes of green hydrogen per year. The hydrogen will be used in ammonia synthesis, enabling the production of around 500,000 tonnes of low-carbon fertilizer and potentially reducing CO₂ emissions by 30,000 tonnes annually.

This marks Uzbekistan’s first green hydrogen project and represents several milestones for LONGi Hydrogen: its first large-scale deployment in Central Asia, the first successful international operation of a 1000 Nm³/h ‘4-to-1’ electrolyzer system, and the first use of its technology in a green ammonia application outside China.

Designed as a closed-loop system, the facility integrates renewable power, hydrogen production, and ammonia synthesis to support industrial decarbonization.

고려아연은 최근 5년간 신재생에너지 분야에 누적 1조원 이상을 투자했다고 9일 밝혔다. 올해 신재생 중심의 '그린메탈' 전략을 본격화하며 해외는 물론 국내에서도 인프라 확장에 속도를 내고 있다.

고려아연의 '2024 지속가능경영보고서'에 따르면, 지난해 고려아연의 신재생에너지 투자액은 5666억원으로 전년(492억원) 대비 약 12배 증가했다.

5년간 투자 추이는 △2020년 234억원 △2021년 79억원 △2022년 3675억원 △2023년 492억원 △2024년 5666억원으로 누적 총액은 1조146억원에 달한다. 투자 중심지는 신재생 확보 여건이 유리한 호주다. 지난 2018년 124MW 규모의 산업용 태양광 발전소 '썬-메탈스 솔라팜'을 시작으로, 지난 2021년 현지 자회사 '아크에너지'를 설립했다.

이후 2022년엔 호주 신재생개발사 '에퓨론'을 인수했고 지난해에는 남반구 최대 규모인 923MW급 맥킨타이어 풍력발전소 지분 30%를 확보했다. 이 중 일부(277MW)는 이미 가동 중으로 약 63만가구에 전력을 공급 중이다. 호주 뉴사우스웨일스주에서는 에너지저장장치(BESS) 기반의 '리치몬드밸리' 프로젝트도 추진 중이다. 현재 고려아연이 보유한 현지 신재생 개발 파이프라인은 약 9GW에 달한다.

수소사업 확장도 주목된다. 지난해 착공한 'SunHQ 수소허브'는 올해 초 시운전에 들어갔으며 연간 140t의 그린수소를 생산해 모빌리티 실증에 활용할 계획이다. 장기적으로는 연 100만t 규모의 그린암모니아를 호주에서 국내로 수출하는 '한-호 공급망 프로젝트'도 구상 중이다.

국내 사업도 탄력을 받고 있다. 고려아연은 지난 3월 재생에너지 전력 중개기업 '한화신한테라와트아워'에 33.3% 지분을 투자하며 신재생에너지 전기공급사업(PPA) 시장 진출 기반을 마련했다. 또, 지난해 8월에는 국가산업단지 내 최초로 울산 온산제련소 제1공장에 수소지게차 충전소를 설치했다. 수소지게차 실증사업도 병행 중으로 지난해 5대 도입에 이어 올해 25대를 추가 배치할 예정이다.

Draft royal decree also calls for 1.5% of the H2 used in refineries to be RFNBO by the same date

 

The Spanish government has unveiled a draft royal decree that would transpose the EU’s Renewable Energy Directive (RED III) into Spanish law, with an ambitious target for the use of green hydrogen and its derivatives in the sector.

 

RED III ­says that at least 1% of all transport fuel used in the EU must be RFNBO (renewable fuels of non-biological origin – ie, green hydrogen and its derivatives) by 2030.

 

But Spain has gone one step further, calling for 2.5% of the transport fuel supplied in Spain to be RFNBO by 2030.

 

This is higher than the 1.5% mandate proposed by France and Germany, but lower than the 4% and 5% mandates set by Finland and Belgium, respectively.

 

RED III also sets a target for a 14.5% reduction in carbon intensity in road transport by 2030, compared to 2010 levels, but Spain is aiming for 15.6% in its draft decree, which is now out for public consultation.

 

However, the Ministry for Ecological Transition and the Demographic Challenge, also plans a sub-target for 1.5% of the hydrogen used by oil refineries to be RFNBO by 2030 (to replace fossil H2 in the refining process).

 

Since then, only Romania and the Czech Republic have done so. Other member states have partially transposed some of the transport mandates, while others have released draft legislation only.
