Waste to Value - Value Creation in Icelandic Geothermal Processes

In essence, this project will identify methods for the geothermal sector for producing marketable by-products, such as silica and other minerals, for resale, which can also decrease scaling problems. This will allow geothermal power plants to work more efficiently and gain profit from something that has, up until now, been considered problematic waste. Gerosion is the project leader and the collaborators are GEORG and the Icelandic energy companies Landsvirkjun, HS Orka, and Orka Náttúrunnar. The project has additionally be funded by the Energy Research Fund of Landsvirkjun and GEORG.

Sacrificial Casing for Geothermal wells

The goal of the project is to develop a sacrificial casing that can protect steel casings in geothermal wells against corrosion and high stresses due to thermal expansion so the structural integrity of the wells is not diminished. With the sacrificial casing the lifespan of wells can be increased and can save Icelandic power companies an extensive amount of repair cost and the cost of drilling new wells. Current solutions in the market are not equipped to withstand the harsh geothermal environment, due to the high temperature and the corrosiveness of the geothermal steam. Gerosion wants to use the team’s experience and knowledge in the corrosion of materials and materials selection in geothermal environment to develop a new kind of casing protection. 

Development of Binder Technology that enables the Utilization of Waste Material Fines as Raw Material for Energy Intensive Industrial Processes

Gerosion has various projects ongoing that revolve around the use of industrial waste materials as raw materials for further energy intensive industrial processes. The main focus of the project is problem of waste material fines and how they can be utilized in further processes. Gerosion has developed two methods for this type of waste recycling, either by using an environmentally friendly cement free binder to bind the fines or by using cement based binder. Gerosion is currently working on solutions for large corporations such as Elkem AS and the aluminium smelters. 



Gerosion has been developing environmentally friendly cement-free binder solutions both for the construction and the energy intensive industries. One of Gerosion’s projects in this field is named AlSiment: Transforming hazardous waste of the metallurgical industry into a valuable raw material. That project is a collaboration between Gerosion, the Icelandic aluminium smelters and a ferrosilicon producer. 

Gerosion has recently signed contract with the European Commission for Horizon 2020 SME Instrument Phase 1 grant for the AlSiment project which is intended for exploring and assessing the technical feasibility and commercial potential of breakthrough innovation that small and medium-sized companies wants to exploit and commercialize.


Gerosion is part of a consortium that recently recieved a European Horizon 2020 grant for the project Geo-Coat and the development of novel and cost-effective corrosion resistant coatings for high temperature geothermal applications. The Geo-Coat project is part of the low carbon energy call to develop next generation technologies for renewable electricity and heating/cooling. The full Geo-Coat project title is: Development of novel and cost-effective corrosion resistant coatings for high temperature geothermal applications. The Geo-Coat partners are from the UK, Iceland, Romania and Norway and the project will last for three years.
