Hydrogen and Mobility

Gasroad has contributed to Korea’s advancement of hydrogen fuel cell vehicles and hydrogen industry..

Hydrogen Energy/Mobility
  • CNG, HCNG, LCNG, LFG, Daughter Station Facility
  • H2 Station
  • Fuel Part Test
  • Hydrogen extraction facilities(SMR)

Since its establishment in 2001, Gasroad has been involved in research and development
of fuel systems for Fuel Cell Vehicles (FCVs) from its initial days, starting with design
and production of CNG charging stations and related testing facilities, which are the
foundation of the hydrogen industry.The company has been supplying R&D testing facilities
that meet the testing specifications of Hyundai Motors
and various H2 partner companies for FCVs.

In response to the expansion of the hydrogen economy and increasing adoption of fuel
cell vehicles (FCVs), we have advanced from CNG 25MPa facilities to H2 45MPa systems, developing diverse
testing facilities integrated with 700+ bar hydrogen storage technologies- a crucial pillar of the
hydrogen economy. As a high-pressure gas specialist, we maintain comprehensive expertise,
extensive project execution experience, and proprietary engineering technologies.

In 2005, Gasroad established a performance testing and evaluation system for the container and
components of the LMFC, the first model of the hydrogen fuel cell vehicle (FCV) (45MPa).
Through this, the company secured the technical capability to upgrade various testing facilities
(H2 70MPa) and modify their structures. Currently, Gasroad is the nation's
top high-pressure specialist company, having acquired a license as a general high-pressure gas
manufacturing facility with a 105MPa pressure resistance rating after KGS technical review.
As the nation’s top specialist in high pressure, it is conducting testing and evaluation in accordance
with UN GTR (Global Technical Regulation) No. 13.
