FCEV

Since becoming the world’s first automobile company to successfully mass produce FCEV in 2013,
Hyundai Motor Group has been pulling together all of its resources to popularize FCEV.
The FCEV project, which began from a tiny drop of water, is creating huge ripples around the world
and bringing forth a new era.

Hydrogen energy used in FCEV

Hyundai Motor Group is trying to become more than just a manufacturer of FCEV that use clean hydrogen energy
It is looking to become a first-mover into the “hydrogen society” of the future.

Production of hydrogen

Unlike oil, which is a primary form of energy that can be mined from the ground, hydrogen is an energy carrier. That means, hydrogen has to be produced using other primary energy sources such as lignite, oil, natural gas, etc. or renewable energy sources such as solar power, wind power, etc. Broadly speaking, there are three ways to produce hydrogen.

Production of hydrogen(Sort, Extract (Reforming), Byproduct Hydrogen, Electrolysis)
Sort Extract (Reforming) Byproduct Hydrogen Electrolysis
Production
Method
Reforming natural gas (methane),
LPG, lignite, etc.
using high heat/high pressure
Produced as a byproduct during
production processes
at petrochemical plants or steel mills
Reforming water using electrolysis
produces hydrogen and oxygen
Features Can use existing energy
infrastructure

Produces CO2
Currently, the cheapest method
Produced via an isolating
/refining process
Emits zero carbon
Currently, an expensive method

The production cost and price of hydrogen

Currently, the hydrogen supply in Korea comes from byproduct hydrogen, and it costs approximately KRW 8,000~9,000/kg to purchase. According to a road map developed in order to create an economy that is more inclusive of hydrogen technology, the government plans to lower the price of hydrogen to KRW 4,000/kg by 2030, and KRW 3,000/kg by 2040.

The price of hydrogen depends on its production cost, transportation cost, and operating expenses required to run a hydrogen recharging station. To fulfill its goals (price of hydrogen), the government plans to make hydrogen more competitive from a pricing standpoint by achieving economies of scale through the mass production and distribution of hydrogen.

  • Mass production Extract (reforming) hydrogen;
    Link with renewable energy
    Produce using electrolysis techniques
    Import hydrogen produced overseas
    Other alternatives
  • Mass distribution Construct pipelines
    Use liquid hydrogen
    Other alternatives
  • Hydrogen price Ulsan 7,000 KRW/kg
    Gwangju 8,200 KRW/kg
    Changwon 8,000 KRW/kg
    Chungnam 8,008 KRW/kg
    Express way 8,800 KRW/kg

The storage and transportation of hydrogen

Hydrogen can be stored in a gaseous state or liquid state. It can also be converted into a different compound for storage purposes.

The storage and transportation of hydrogen(Sort, Gas, Liquid, Compound)
Sort Gas Liquid Compound
Storage and
Transportation

Compress hydrogen in its gaseous
state and store in a tank

Cool hydrogen to sub-zero
temperatures (-253℃),
and store in a liquid state

Convert hydrogen into methane,
ammonia (liquid), MCH (liquid),
etc. or store onto a metallic medium

Principle Transport highly pressurized gas
produce hydrogen → Compress(200~450 bar) → Transport using pipelines, pressurized tanks
Transport liquefied gas
produce hydrogen → Hydrogen liquefaction plant(-253℃) → Transport
Transport using ammonia, etc.
Ammonia:Chemical bonding (hydrogen+nitrogen) → Transport → Isolate hydrogen
Features

Pipelines to transport hydrogen (e.g.
tube trailers, pipelines, etc.) require
an initial outlay of investment.

However, they are the cheapest
alternative.

Requires high investment costs,
large quantities of hydrogen can
be stored in a highly efficient
manner.

Use supertankers/tankers
transport at normal
temperatures/pressure.

※ MCH : Methyl CycloHexane (Liquid organic compound created via a reaction between toluene and hydrogen)
