6 FAQs about [Storing mechanical energy Greenland]

Does Greenland have a place-based approach to energy production?

The lack of electricity transmission between urban settlements in Greenland necessitates a place-based approach to energy production. In keeping with this, this case from Greenland is intentionally laid out differently to the others in the Handbook.

Why is Greenland introducing small wind power parks?

Greenland is introducing small wind power parks in orderto supply energy to those areas inaccessible by electricity cables. In addition, the government is investing in new technology for storing and transporting excess energy.

Is Greenland a potential E-Fuels hub?

Greenland's transition from a fossil fuels-based system to a 100% renewable energy system between 2019 and 2050 and its position as a potential e-fuels and e-chemicals production hub for Europe, Japan, and South Korea, has been investigated in this study using the EnergyPLAN model.

Does Greenland have a decentralised energy system?

No comprehensive study on Greenland has been found, as existing studies focus on small individual communities. Such studies provide a tailored perspective on decentralised energy systems, considering local climate conditions, energy demand, and quality of local renewable resources.

How does heating work in Greenland?

In the reference system, a major share of heating in Greenland is supplied by district heating, which is dominant in larger towns. However, as the population density is quite low and towns are dispersed, many households use oil for heating, constituting 57% of total heat production. Another 15% of heat is supplied by electricity.

How does a mechanical facility store electricity?

A different kind of mechanical facility stores electricity by using it to compress air, then stashes the air in caverns. “When the grid needs it, you release that air into an air turbine and it generates electricity again,” explains Jon Norman, president of the Canada-based company Hydrostor, which specializes in compressed-air storage.
