Properties and occurrence

Hydrogen is the most common element in the universe.


It is the lightest chemical element, a colorless, odorless gas, poorly soluble in water, which normally appears as the H2 molecular form. At 0⁰C and 1 atm. is 14.4 times lighter than air. From the point of view of potential storage the low critical hydrogen temperature (-239,9⁰C) is an important parameter, which makes condensation of this gas more difficult than liquefaction of air or most other gases.


It causes serious difficulties in hydrogen storage and transport, and basically we can only compress it to a very high pressure of up to 700 atm nowadays. The unique property of hydrogen is its considerable solubility in some metals. At high temperatures, it dissolves in: platinum, nickel, iron, copper. On one hand, it is a chance to increase the capacity of hydrogen tanks, but can also be a serious problem related to the so-called hydrogen corrosion, such as penetration of hydrogen molecules into the metal structure. It has a significant impact on the durability of e.g. metal reactors and tanks. Currently, multi-layer composite tanks are used to prevent the phenomenon of hydrogen penetrating the walls of the tanks. Intensive research is  conducted to find the most effective hydrogen storage way.


The main sources of hydrogen are: water and organic compounds, mainly based on carbon and hydrogen atoms. So obtaining pure hydrogen requires the use of an appropriate portion of energy.

Webinar: South Korea - Hydrogen market cooperation opportunities for EU companies and Korean Investors

Global decarbonization and ongoing war in Ukraine enforce even faster actions for new energy sources. All countries looking into hydrogen are I the same time building partnerships, as no one alone is able to achieve this transition.

If you wish to understand South Korean and EU hydrogen market to find cooperation and investment opportunities it is the best webinar for you.

It is also a chance for EU an Korean investors to see Polish and EU investment incentives and business support schemes for hydrogen technologies development.

Webinar agenda:

Introduction by - Piotr Maksyś, Cluster of Hydrogen Technologies, Poland
H2Global Project - EU perspective for hydrogen development - Ms. Agata Horwacik
H2Korea and Korean Hydrogen Strategy - Ms. Hyejin Lee
Polish Hydrogen Strategy - Mr. Marek Foltynowicz
Pomeranian Special Economic Zone - Mr. Igor Nagraba
Q/A session
Short market overview:

South Korea (Korea) has set itself ambitious goals for its hydrogen economy for 2030 and beyond but is already a global leader in the transition to hydrogen: the country boasts almost half of the world's installed capacity of utility-scale stationary fuel cells and its largest automotive company, Hyundai Motor Company, has suppliedalmost 60% of the world's Fuel Cell Electric Vehicles (FCEV) since launching its first
commercial fuel cell vehicle in 2013. Korea is now looking to build on these strong foundations, a strategy that enjoys broad support across both the public and private sectors.

The EU strategy on hydrogen was adopted in 2020 and put forward a vision for the creation of a European hydrogen ecosystem from research and innovation to scale up production and infrastructure to an international dimension. Hydrogen is also an important part of the EU strategy for energy system integration. The strategy explored how producing and using renewable hydrogen can help decarbonise the EU economy in a cost-effective way, in line with the European Green Deal, and contribute to the post-COVID-19 economic recovery.
