Early Origins and Strategic Purpose

Prøvestenen’s foundation in 1713 was integral to Copenhagen’s maritime defense. Created by sinking the floating dock “Prøvestenen” off Amager’s eastern shore, it formed a marine battery safeguarding the crucial harbor entrance. This strategic outpost was vital for controlling access between the Baltic Sea and Western Europe via the Øresund strait. Despite environmental challenges, Prøvestenen remained in use—albeit intermittently—until the late 18th century. (Wikipedia) (palplanches.arcelormittal.com)

18th and 19th Century Fortifications

Throughout the 18th and 19th centuries, Prøvestenen underwent several expansions. Notably, it played a role in the 1801 Battle of Copenhagen. The most enduring construction, completed between 1859 and 1863 by architect Ferdinand Meldahl, is recognized as one of Denmark’s oldest concrete structures. Remnants of these fortifications still exist on the island today. (da.wikipedia.org) (hovedstadshistorie.dk)

Decommissioning and Industrial Transition

After its official military decommissioning in 1922, Prøvestenen transitioned into a vital industrial site. Initially repurposed for petroleum storage by the Royal Danish Navy, it was later managed by the Copenhagen Port Authority. This period saw the development of a dedicated petroleum harbor, embankments, and railway connections, marking Prøvestenen’s evolution into a logistical hub. (da.wikipedia.org) (hovedstadshistorie.dk)

Expansion and Modern Use

Prøvestenen’s role as Copenhagen’s main petroleum harbor was solidified after extensive post-WWII land reclamation. In the 2000s, a significant expansion added 180,000 square meters and a 650-meter quay, enabling the accommodation of large vessels and further reinforcing its industrial significance.

Prøvestenen Today: Energy Infrastructure and Sustainability

Currently, Prøvestenen is home to Oiltanking Copenhagen’s storage terminal, connected via pipeline to Copenhagen Airport. The site is central to Denmark’s energy supply chain and supports the country’s ambitious climate goals, especially through the distribution and storage of sustainable aviation fuels (SAF) and the development of Power-to-X (PtX) technologies.

Prøvestenen is also a hub for innovative green initiatives such as carbon capture and storage (CCS). In partnership with ARC and other stakeholders, Prøvestenen facilitates the transport and shipping of captured CO₂ for storage or potential use in future green fuel production. Its three wind turbines, operated by local cooperatives and Hofor, further contribute to Copenhagen’s renewable energy targets. (Shell Aviation) (Green Power Denmark)
