The initiative was set up by local councils to highlight renewable energy opportunities in the Humberside area.
Green Port Hull said the business desk in Copenhagen would be an initial point of contact for Danish companies wishing to invest in the region.
The British Chamber of Commerce in Denmark will run the desk and will work closely with the Hull and Humber Chamber of Commerce. Chambers of Commerce represent UK business interests in areas around the world.
"The aim of the desk is to facilitate relationships and encourage partnerships between businesses here in the UK and in Europe through European Chambers. We will be an initial point of contact and will manage the signposting process. Not only will this partnership attract inward investment to the Humber region but it will also support UK businesses," explained Pauline Wade, director of international trade at the Hull and Humber Chamber of Commerce.
It is hoped the £310 million (€390 million) investment by Siemens and the Associated British Ports to set up a blade manufacturing facility and turbine assembly plant at Alexandra Dock would attract some businesses to the region and strengthen the supply chain.
Siemens expects production of turbine blades to begin by the end of 2016.
