The port of Wallhamn AB is located on the Swedish island of Tjörn, to the north of Denmark. Its aim is to become the “first port with a negative carbon footprint in the world.” And to achieve this, the municipality has enlisted the services of Luxembourg-based Boson Energy.

The Hollerich-headquartered company has developed a technology for producing green electricity and methanol from waste that is considered non-recyclable. “Green methanol replaces fossil methanol in the chemical and plastics industries, while meeting the growing demand from the maritime sector,” the firm stated. The company plans to meet Wallhamn AB’s energy and electricity needs for vehicle recharging, as well as supporting the local electricity grid when required. “The only solid residue from the conversion process is a glass slag. It can be used directly, as an environmentally friendly filling material, or converted into climate-smart insulation material with high circular resource efficiency.”

As part of the project, Boson Energy has also signed a cooperation agreement with Ecopromt AB to build an indoor agricultural facility for growing vegetables near the port.

The proposed facilities are due to come on stream in 2025 at the earliest. The activities are expected to create 150 to 200 job opportunities in the municipality of Wallhamn. The project could cost a total of €450m, according to Boson Energy.

The company recorded a loss of €2.5m in 2021 and employs seven people, according to the Luxembourg business register (RCS).
