Detail from the Stepwise facility, a part of Swerim’s research on hydrogen gas.

​A new project led by RISE and Swerim aims to reduce industrial climate emissions using large-scale electrolysis.

The project is called State of the art assessment of industrial-scale electrolysis – Case study and is ongoing during 2020 with financing from the Swedish Energy Agency and an industrial consortium of ten organisations;  all participants of the test bed project Swedish Hydrogen Development Center. 

The aim is to investigate the possibilities of reducing two Swedish process industries´ climate emissions by up to 33 kton/year by replacing parts of their current processes with large-scale electrolysis, thereby contributing with an increased knowledge base on hydrogen from electrolysis.

The case studies will be completed on two different geographical locations:

  • Replacement of hydrogen from natural gas reforming at Höganäs, a world leader on the market for iron and metal powders.
  • Replacement of fossil carbon at Boliden, a high-tech metal company with its own mines and smelters.

The studies include mapping, analyses of requirements profile, conditions for different electrolysis technologies, LCC analyses, analyses of process risks, environmental impacts and sustainability, by-products and energy market aspects for the different industries.

The specific goal is to provide Boliden and Höganäs with a basis for deciding on further investments in large-scale electrolysis in the form of pilot tests and/or introduction of the technology at large scale.

The results will also meet the expressed needs of energy companies, electrolysis suppliers and other industries.

In addition to Höganäs and Boliden, the following industrial partners are included in the project: AGA Gas, Sandvik Materials Technology, Fortum Sweden, Haldor Topsoe, Euromekanik, Siemens Industrial Turbomachinery, HydrogenPro and Liquid Wind.
