Bioenergy is thriving in Akureyri

Electric Car

Renewable energy, including bioenergy, is thriving in the town Akureyri, in northern Iceland, with the community actively moving in the direction of carbon neutrality. The energy transition team at Orkustofnun visited Akureyri in order to look into the current status of renewable energy in transport and in utilization of biomass in the Eyjafjörður Area, northern Iceland. Orkustofnun’s branch in Akureyri was visited, and Guðmundur H. Sigurðarson, Managing Director of Vistorka, presented the company’s activities and the status of these issues including achieving carbon neutral society in Akureyri.

Several charging stations for electric cars are available for use in Akureyri and some of them where visited. The stations are owned and operated by ONNorðurorka and Rarik. Vistorka received funding from the Energy Fund for development of infrastructure for electric cars which will result in 11 electric charging stations in the North of Iceland. Most of the projects described below have been funded by the Energy Fund as well as supported by Orkusetur.

The compost company Molta was visited, where organic waste is collected from homes and companies in the Eyjafjörður Area and beyond for compost production. Production of biodiesel from animal waste is planned at the facility. The company Orkey was also visited, where biodiesel is produced from waste cooking oil. The biodiesel is used in buses in Akureyri, on fishing vessels and in asphalt production. The aim is to increase production by adding animal waste as mentioned previously. Methane is currently produced from the old landfill in Akureyri and “harnessing” of the manure in the Eyjafjörður area is on the drawing board to further increase methane production to fuel 2-3000 cars per year.

The use of electric bikes by the employees of Norðurorka is also of interest, as electric bikes are relatively inexpensive, convenient in a hilly and windy environment and use a renewable power source. In winter the bikes’ studded tyres are well suited for icy conditions as well as the on-board lighting system is important for safety in the darkness of the Arctic winter. The energy transition team at Orkustofnun has many irons in the fire these days and are gathering ideas that help accomplish Althingi’s action plan regarding energy transition. In order to meet such goals, it is clear that applying well-known and successful methods and technologies are important. Orkustofnun, Orkusjóður and Orkusetur will continue to support projects in the field of energy transition throughout the country.

Ireland’s forestry cover now at 10% of land area

Lumber stacks

One in every 10 hectares of land is now planted in forestry, according to the latest figures. The Government’s Forestry Statistics paint a picture of the country’s afforested grounds amid increasing pressure to up volume of lands under trees due to greenhouse gas emissions targets. Despite Ireland falling far short of planting targets, the area of forest is estimated to stand at 731,650ha or 10.5% of the total land area of the country. Around 53% or 389,356ha is in public ownership, mainly Coillte.

The forested area acts as a carbon reservoir, amounting to 381 million tonnes of carbon in 2012 and between 2008 and 2012 it removed 16Mt of CO2 and offset 5% of all national emissions. There have been major concerns raised in western counties, particularly Leitrim, over the level of forestry planting in the region. Farmers account for 83% of private lands afforested between 1980 and 2016, with the average size of private grant-aided plantations around 8.8ha since 1980. It states farmer planting has dominated afforestation since 1993. With farmers and non-farmers now eligible for the same rate of grants and premium payments, the number of non-farmers planting has increased to 35% of the areas afforested in 2016. It points out that ‘non-farmers’ include retired farmers, sons and daughters of farmers and other relatives who may have inherited land.

Forestry and its role in carbon sequestration is an obvious part of any solution to the problem of emissions produced by agriculture. In 2016, Cork had the highest afforestation area at 608ha, followed by Clare at 552ha, Roscommon at 435ha, Leitrim at 434ha and Mayo at 429. There were 34 ‘non-farmers’ who accounted for 254ha in Cork in 2016, while 33 accounted for 238ha in Clare, 26 for 212ha in Cavan and 28 for 195ha in Leitrim. Efforts have been made recently to increase the volume of broadleaves planted by the Agriculture Department, with increased grant incentives, as the forest estate is made up of three quarters conifers and one quarter broadleaves. Sitka spruce is the most common species, accounting for 52% of the forest area. The report warns tree diseases impacting species such as larch and Chalara fraxinea or ash dieback may influence diversity into the future.

Carbfix project – from gas to rock

About Carbfix project – from gas to rock

CarbFix is a collaborative research project between Reykjavik Energy, the University of Iceland, Columbia University and CNRS that aims at developing safe, simple and economical methods and technology for permanent CO2 mineral storage in basalts. The CarbFix team had demonstrated that over 95% of CO2 captured and injected at Hellisheidi geothermal Power Plant in Iceland was mineralized within two years. This contrasts the previous common view that mineralization in CCS projects takes hundreds to thousands of years. Industrial scale capture and injection have been ongoing at the power plant since 2012. This project has evoked reactions worldwide as global warming is dangerously approaching 2°C which is seen as having catastrophically consequences.

Why Carbon Capture and Storage (CCS)?

According to the Intergovernmental Panel on Climate Change (IPCC), global warming of more than 2°C would have serious consequences, such as an increase in the number of extreme climate events. The Paris agreement from the Paris climate conference (COP21) in December 2015 sets out a global action plan to limit global warming to bell below 2°C. The agreement is the first ever universal, legally binding global climate deal.

To reach this target, climate experts estimate that global greenhouse gas (GHG) emissions need to be reduced by 40-70% by 2050 and that carbon neutrality (zero emissions) needs to be reached by the end of the century at the latest. The International Energy Agency (IEA) has furthermore estimated that carbon capture and storage is vital if the world is to limit global temperature increase to 2°C.

CarbFix for future reduction of greenhouse gases

Reducing industrial CO2 emissions is considered one of the main challenges of this century. By capturing CO2 from variable sources and injecting it into suitable deep rock formations, the carbon released is returned back where it was extracted instead of freeing it to the atmosphere.  This technology might help to mitigate climate change as injecting CO2 at carefully selected geological sites with large potential storage capacity can be a long lasting and environmentally benign storage solution.

To address this challenge, the CarbFix project is designed to optimize industrial methods for storing CO2 in basaltic rocks through a combined program consisting of, field scale injection of CO2 charged waters into basaltic rocks, laboratory based experiments, study of natural analogues and state of the art geochemical modeling. A second and equally important goal of this research project is to generate the human capital and expertise to apply the advances made in this project in the future.

Details and results of this research program, including regular updates, can be found on this website https://www.or.is/english/carbfix-project/about-carbfix

The objectives and procedure behind Carbfix project

The main objective is to develop new method and technology for capturing CO2 and H2S emission and turn into rock, carbon and Sulfur fixation so to speak. Basalt plays key role in the mineralization process as it contains high amount of calcium, magnesium and iron and these chemicals interact with CO2 and H2S to form minerals. They form Calcite from CO2 and fools gold from H2S.

The procedure is described as injecting the captured gas into the earth again, where they were originated. It involves separating CO2 and H2S from other gases in the scrubbing system. During scrubbing the gases CO2 and H2S are dissolved in water resulting in a type of mineral water. This water is then injected into basaltic host formation and the outcome is fools gold from CO2 and Calcite from H2S. The mineralization takes about 2 years and is stable for centuries or even millions of years.

The method developed can be utilized wherever carbon dioxide is emitted in the vicinity of basaltic rock and water and sea. These conditions are widely found on the planet.

What are the goals of CarbFix?

CarbFix is aimed at developing new methods and technology for permanent CO2 mineral storage in basalts. This is done through a combined program consisting of:

  • field scale injection of CO2 charged waters into basaltic rocks
  • laboratory based experiments
  • study of natural analogues
  • geochemical modeling

A second and equally important goal of this research project is to generate the human capital and expertise to apply the advances made in this project in the future as mentioned above.
