The three year old Andreas Anuik Hardenberg, had the honor of placing the key in the lock of the first hydrogen plant in Greenland. It is the national energy company, Nukissiorfiit, that has procured the mobile plant which is now installed and in operation outside the company headquarter in Nuuk, the capital of the country. The plant has been developed by H2 Logic A/S from Denmark. Purpose of this test plant is to gain experiences with production, distribution and use of hydrogen as energy carrier and investigate the opportunities for increasing the renewable energy share in the energy production from Nukissiorfiit. Today around 60% of the energy – electricity and heat – that Nukissiorfiit produces for the entire country comes from hydro power. The remainder is produced by use of expensive and polluting diesel. With a continuous increase of production capacities of hydro power plants in combination with hydrogen and fuel cells, it may in the long term be possible for Nukissiorfiit to completely avoid use of diesel for electricity and heat production. Hydrogen could then also be used as fuel for the transportation sector and using the extra potential of hydro power. Even the export of hydrogen may be a long term opportunity.
