Emissions Will Increase by 10% if Silicon Plant Reopens

Iceland’s greenhouse gas emissions will increase by over 10% if the silicon plant in Helguvík resumes its operations, RÚV reports. This data was provided by the Environment Agency of Iceland in response to a direct inquiry from the news agency. Stakksberg, a subsidiary of Arion Bank which took over the plant after it went bankrupt, is currently renovating it with plans to sell.

From the time of its opening, the Helguvík silicon plant, previously owned by United Silicon, was plagued by operational troubles and ultimately went bankrupt amidst widespread community outcry over the environmental and health impact it was having on the surrounding communities.

At maximum production – that is, 100,000 tonnes of silicon metal annually – Stakksberg’s newly refurbished plant in Helguvík would produce 550,000 tonnes of carbon dioxide per year. Based on figures from 2017, Iceland’s total overall greenhouse emissions would therefore increase by at least 10% if the plant goes back into production.

There’s also a chance that Stakksberg’s plant would be joined by yet another, even larger silicon plant owned by the company Thorsil. Thorsil was given an operational license in 2017 and, if its plant produces at its maximum capacity – 110,000 tonnes of silicon metal annually – it will generate 605,000 tons of CO2 per year. The Environment Agency said that these figures must be treated as theoretical at present, however, as neither factory is currently in production.

Under the terms of the Paris Agreement, as of 2030, European Union nations will reduce their carbon emissions by 40% (based on the levels they were in 1990). Although not part of the European Union, Iceland has ratified the agreement on the understanding that the country will reduce its emissions by a fiscally responsible and manageable percentage. It has now been determined that Iceland only needs to reduce emissions by 29% (based on 2005 levels) by 2030. Despite this, Iceland has approved a climate change strategy that still seeks to reduce emissions by the Paris Agreement levels of 40%. Prime Minister Katrín Jakóbsdóttir has taken this goal even further, setting a goal of making the country entirely carbon neutral by 2040.

Nevertheless, the government’s action plan on climate change does anticipate that up until 2030, emissions from heavy industry in Iceland will increase considerably. From 1990 until 2016, emissions increased 106%.

A silicon plant went into production at Bakki, near Húsavík in North Iceland in 2018. In addition to the two silicon plants that may be soon up and running in Helgúvík, a number of other plans for additional heavy industry projects are also in the works. but, in the words of the government’s action plan on climate change, “[s]ignificant reduction of carbon emissions in Iceland is unlikely to be possible in this sector without the emergence of new technologies, such as inert electrodes in the production of aluminum or the collection and injection of carbon dioxide.”
