Description Vendor

The G-Philos ALK Linked System is a 1MW class water electrolysis system designed to produce approximately 430kg (200Nm³/hr) of hydrogen per day, capable of fueling up to 85 hydrogen cars. It comprises 100-stack modules, each with a power output of 10kW, ensuring efficiency in quality management, maintenance, power variance control, and scalability of system capacity. The system has a stack power consumption of up to 100kW (10kW x 10 module), water consumption of 10 liters per kg of H2 produced, and produces hydrogen with a purity of up to 99.999%. It has a start-up time of 1 minute warm and 10 minutes cold, with an average stack efficiency of 50.07 kWh/kg and an average system efficiency of 53.88 kWh/kg. This system is ideal for applications requiring high hydrogen production and reliability, making it a key solution for sustainable energy and transportation.

Use Cases

  • Hydrogen generation for fueling up to 85 hydrogen cars
  • Power-to-Gas and industrial hydrogen supply

Capabilities

  • Hydrogen output 200 Nm³/h (≈ 430 kg/day) at 7 bar (103 psig).
  • Stack efficiency ≈ 50 kWh/kg; system ≈ 54 kWh/kg.
  • Rapid start-up (1 min warm / 10 min cold)
  • Water use 10 L per kg H₂ produced.
G-Philos Co., Ltd G-Philos Co., Ltd, founded in 2009 and headquartered in Giheung-gu, Yongin, Gyeonggi-do, South Korea, specializes in power conversion systems based on renewable energy and was designated a Hydrogen Specialized Company by Korea's Ministry of Trade, Industry, and Energy in 2021. As a leader in renewable energy-integrated Power-to-Gas (P2G) systems, G-Philos has been converting wind power into green hydrogen on Jeju Island since 2017, constructing Korea's first renewable energy-linked green hydrogen production testing site at the Sangmyeong Wind Power Complex in partnership with Korea Midland Power Co., using an electric buffer device between irregular renewable output and the electrolysis device for stable P2G operation. The company holds the highest market share for small- to medium-capacity fuel cell power conversion devices in Korea, with its HiGen-C and HiGen-V series grid-linked inverters converting DC power from fuel cell stacks (even at low voltages of 10.2V) to AC power with precise, stable stack optimization control algorithms, having passed 5,000 units of total fuel cell inverter production. Marking its 17th anniversary with a 2028 target to become a broader clean-energy solutions company, G-Philos also signed a Memorandum of Understanding with the Investment Board Nepal to develop a green hydrogen and fuel cell plant in Nepal, offering complete green hydrogen production total solutions spanning P2G engineering, hydrogen storage systems (low-pressure, high-pressure, and metal hydride storage), and fuel cell installation and support businesses.
