About us


Høst is a project in the CI Energy Transition Fund I managed by Copenhagen Infrastructure Partners (CIP). The CI Energy Transition Fund I focuses on the next generation of renewable energy infrastructure including industrial scale Power-to-X (PtX) projects and the decarbonization of the so-called hard to abate industries such as shipping, land transport and aviation using green fuels.

The HØST PtX Esbjerg project marks the first investment in the CI Energy Transition Fund I on Danish ground, and the project team is operational on site working from CIP's office in Esbjerg, Denmark.

Project description

HØST PtX Esbjerg is a leading, Danish Power-to-X (PtX) project, deploying large-scale industrial use of electrolysis-technology on GW-level to produce ammonia. The ammonia plant will be powered by green electricity from renewables, harvesting the kinetic energy from wind and solar. Based on this CO2-free production process, HØST PtX Esbjerg will be able to offer green ammonia to the market for use in fertilizers and in fuels.


Thereby, HØST PtX Esbjerg is opening the door to decarbonization of hard-to-abate sectors such as shipping, agriculture and industrial applications. Excess heat from the plant will be used for district heating of app. 15,000 households, reducing the carbon footprint of the local utility company, DIN Forsyning. Moreover, the 1GW plant is the ideal, green offtake companion to the continued build-out of low-cost, renewable electricity generation capacity in the North Sea.

Project partners

Because HØST PtX Esbjerg has great potential to decarbonize agriculture and shipping, a number of Danish industry giants are supporting the project. The agricultural majors are DLG, Danish CrownArla and Danish Agro, who through their consortium Green Fertilizer Denmark are planning to use green ammonia in fertilizer production. Leading shipping and logistics companies such as MonjasaDFDS and Maersk are looking into using green ammonia as a climate-friendly fuel for the maritime sector. Local utility company DIN Forsyning and local municipality Esbjerg are also project partners supporting the local initiatives around sector linkage and energy efficiency.

Next generation renewables

HØST PtX Esbjerg will be among the first gigawatt-scale PtX facilities in Europe, contributing to the much-needed acceleration of the decarbonization journey towards carbon neutrality in 2050. Moreover, it will be a key driver for the establishment of a new industry within next-generation renewables in Esbjerg and in Denmark.
