As South Korea and Australia work to achieve ambitious net zero emissions targets by 2050, the development of clean hydrogen infrastructure has become a major priority. However, transporting hydrogen comes with unique challenges due to its chemical properties. This is where Nexa Pipe’s innovative pipe and pipeline relining solutions can play a crucial role in enabling safe, efficient and sustainable hydrogen pipeline infrastructure.

The Drive Towards Clean Hydrogen in South Korea and Australia

Both South Korea and Australia have pledged to reach net zero greenhouse gas emissions by 2050. This will require a major transition away from fossil fuels to clean energy sources like hydrogen.

South Korea in particular faces pressing energy security issues as it currently imports over 90% of its energy needs. Developing domestic clean hydrogen capabilities can help South Korea achieve energy independence and fuel diversity. The South Korean government has set out bold plans to expand its hydrogen economy, including:

  • Installing over 1,000 hydrogen refueling stations nationwide by 2040
  • Achieving over 5 million tons of green hydrogen production capacity by 2030
  • Developing capabilities to import clean hydrogen from overseas partners

Australia has also identified clean hydrogen exports as a major economic opportunity. With its abundant land and renewable energy resources, Australia aims to become a major global exporter of clean hydrogen. Australian companies are actively developing large-scale green hydrogen production hubs to supply international markets.

The Challenges of Transporting Hydrogen

While hydrogen holds great potential as an emissions-free fuel, effectively transporting it poses complex technical hurdles:

  • Hydrogen gas is difficult to transport efficiently over long distances through pipelines due to hydrogen embrittlement issues that compromise pipe integrity.
  • Liquid hydrogen avoids embrittlement but requires cooling hydrogen down to extremely low cryogenic temperatures below -253°C. This results in major energy losses.
  • Converting hydrogen to liquid organic hydrogen carriers like ammonia allows easier transport but also leads to some conversion losses.

Building safe, efficient, very long-distance hydrogen pipelines is key for unlocking hydrogen’s potential at scale. This is where Nexa Pipe’s innovative solutions can make a major impact.
