Summary 

Höegh Evi, together with Wärtsilä Gas Solutions and partners, has successfully piloted the world’s first ammonia cracker designed for floating terminals. This breakthrough enables industrial-scale hydrogen production onboard, using ammonia transported by ship as an affordable, scalable energy carrier.

Challenge 

The EU aims to consume 20 million tonnes of renewable hydrogen annually by 2030. Half of this is expected to be imported, largely from regions where hydrogen is produced with abundant, low-cost renewable power. However, transporting hydrogen is difficult due to low volumetric energy density and risk of losses of vaporization. 

Ammonia crackers being built onshore face a number of challenges: limited available land in congested port areas, high construction costs, long timelines, and complex permitting processes.   

Solution 

Floating terminals offer a pragmatic, space-efficient and cost-effective way to quickly expand Europe’s hydrogen infrastructure. 

Marine carriers transport clean hydrogen from overseas in the form of ammonia, which is received by floating terminals. The ammonia is then “cracked” back into hydrogen through a warming process without producing emissions. The energy is delivered into the European hydrogen backbone where it is available for industrial consumption.   

Höegh Evi’s modular design also allows adaptation to market needs while maintaining energy security. The industrial-scale ammonia cracker can be integrated into hybrid floating storage and regasification units (FSRUs) or installed on dedicated floating hydrogen terminals, delivering large volumes of baseload-ready hydrogen at a highly competitive price. 

The project has received approximately EUR 5.9 million in funding from the Norwegian Government’s green platform programme, representing approximately 50% of the total budget. The ammonia cracker was constructed at Sustainable Energy’s Norwegian Catapult Center in Stord, Norway. Additional partners in the project include the Institute for Energy Technology (IFE), University of South-East Norway, Sustainable Energy and BASF SE.   

Impact 

Summary 

The carbon capture and storage (CCS) partnership between Höegh Evi and Aker BP is a significant step in accelerating industrial decarbonisation across Europe. Together, we offer a flexible maritime CCS value chain to reduce emissions from hard-to-abate industry at scale and speed. 

The fully integrated solution includes the entire value chain from collection of CO2 to permanent subsea storage at the Atlas and Poseidon reservoirs on the Norwegian Continental Shelf. With a fully marine-based system, we can provide a seamless solution that lowers the barriers to entry for medium- to smaller-scale emitters.

Challenge 

CCS is viewed by the EU as key to achieving its ambitious target of 55% reduced emissions by 2030(compared to 1990)* which would require 50 million tonnes of CO2 storage capacity per year by 2030.  As of mid-2025, the EU has around 10 million tonnes per year of operational CO2 storage capacity- around 80% behind the target, and five years to go.   

While there is strong governmental support for CCS, project development has lagged due to delays and lack of decisions in the capturing side by the industry, need to build extensive pipeline infrastructure, fragmented regulation, slow permitting processes, high infrastructure costs, long construction timelines, congested port areas and limited access for smaller emitters.   

Solution 

Now, Höegh Evi and Aker BP have combined their strengths to offer a fast, seamless, and cost-effective alternative: a fully maritime CCS value chain.  

The solution overcomes the challenges of cross-border and regulatory fragmentation by connecting emitters across Europe with permanent North Sea storage using ships.  

The CO2 is received by floating CO2 terminals (FCSO), coming from various sources- pipelines, ships, trains or trucks. The CO2 can be compressed, liquefied and purified to offshore injection standards at the FSCO.  

Next-generation shuttle carriers then collect and transport the CO2 to the Atlas and Poseidon reservoirs on the Norwegian Continental Shelf. It is injected directly at the storage site, eliminating the need for costly onshore terminals pipelines. The flexibility of the solution allows industrial emitters of all sizes to participate, making CCS broadly accessible and creating a resilient pan-European CCS network.

Summary 

The H2 Import Terminal in Lubmin, Germany, will be the world’s first floating import terminal for green hydrogen. The floating terminal repurposes LNG infrastructure to import and convert green ammonia into hydrogen on an industrial scale, and help Germany realize its decarbonization goals.

Challenge 

The acceleration of energy transition in Germany, particularly in decarbonizing its industrial sectors, will require new infrastructure solutions that can efficiently handle large quantities of green hydrogen and supply it into the country’s core hydrogen network. 

Solution 

Höegh Evi has partnered with Deutsche ReGas to develop the “H2-Import-Terminal Lubmin.” Utilizing Höegh Evi’s green ammonia cracker technology, the terminal will efficiently convert green ammonia into hydrogen. Our approach leverages existing marine infrastructure to provide a cost-effective and rapid method to bring hydrogen into Germany’s energy market.
