There are not many possibilities to visit such construction sites, as the opportunity to expand hydropower is often restricted because of environmental or regional regulations limitations. However, the study trip, which was primarily designed for the visitors from Vattenfall, gave a broad insight in the countries geology, energy resources and production, as well as industrial development in general. This report gives an overview of the trip, summarizes information and presents pictures and images. I want to thank Vattenfall as organization, as well as a large number of individuals at Vattenfall, for giving me the opportunity for participation. Further, I want to express my sincere gratitude to the Swedish Hydropower Center, i.e. Svensk Vattenkraft Centrum SVC, Luleå University of Technology, and individuals at Elforsk for providing me the possibility to take part in this excursion. It has been of great value for me as a young person with deep interest in dam design and construction and provided me with invaluable insights. Luleå, May 2007 Isabel Jantzer Agenda During three days we had the possibility to travel over the country: After the first day in Reykjavik, we flew to Egilstadir in the north eastern part of the country, from where we drove to the Kárahnjúkar dam site and visited the Alcoa aluminium smelter at Reydarfjördur Fjardaál afterwards.

  • Legal Framework and National Policy for Geothermal Development in Iceland
    Proceedings World Geothermal Congress 2015 Melbourne, Australia, 19-25 April 2015 Legal Framework and National Policy for Geothermal Development in Iceland Jonas Ketilsson, Harpa Th. Petursdottir, Skuli Thoroddsen, Anna L. Oddsdottir, Erna R. Bragadottir, Maria Gudmundsdottir, Gudni A. Johannesson Orkustofnun, Grensasvegi 9, IS-108 Reykjavik, Iceland Corresponding author: [email protected] Keywords: Legal, law, energy, regulatory, official, monitoring, geothermal, statistics, policy, Master Plan, Iceland, Europe. ABSTRACT In this paper, a description is given of the national policy, legal framework, official monitoring and accumulation of geothermal energy statistics in Iceland in a global context. The legal framework and amendments to the energy legal framework since 2010 will be reviewed. In particular the effect of Act for the Master Plan for the Utilization and Protection of Energy Resources no. 48/2011 which sets up the legal framework for the Master Plan which has been in preparation since 1999, where geothermal and hydro resources are categorized to be exploited, protected or further researched. It is the policy of the Government of Iceland to increase the utilization of energy resources and hence governmental support was increased for new geothermal based heat utilities by 50% even though 9 out of 10 households are heated with geothermal energy. The Icelandic National Renewable Energy Action Plan was published in year 2012 in accordance with Directive 2009/28/EC which outlines the strategy for 2020 and goals of geothermal utilization. In accordance with the plan, electricity generation from geothermal sources is estimated to increase by 12% from 5.2 TWh in year 2014 to 5.8 TWh in year 2020 and geothermal heat use from 28.1 PJ in year 2014 to 34 PJ in year 2020.

  • Iceland As a Case Study
    Sustainable Energy Development: Iceland as a Case Study Brynhildur Davidsdottir, Environment and Natural Resources, University of Iceland ABSTRACT Increasing energy prices, political unrest in the Middle East and climate change are only a few issues that have pushed planning for Sustainable energy development (SED) onto the political horizon. SED is broadly defined as ‘the provision of adequate energy services at affordable cost in a secure and environmentally benign manner, in conformity with social and economic development needs’. Planning for SED implies that we need to consider the three dimensions of sustainable development, where such movement should not have negative consequences for the economy, the public (social dimension), nor the environment. This paper presents the development of the Icelandic Energy System since the year 1900 in this context. Iceland has in the last 40 years gone from being mostly reliant on coal and oil, towards extracting 73% of its primary energy needs from renewable energy, and at the same time achieved impressive economic success. Only the transportation sector relies on fossil fuels, and various experiments are being conducted to significantly reduce the reliance on imported fossil fuels. Some of those experiments include planning for a hydrogen economy by 2050. A central question that is asked in this presentation is if Iceland’s path is indeed sustainable, if it is unique and if other countries possibly can do the same. Sustainable Development Introduction Since the publication of the Brundtland Report (WCED 1987), sustainable development (SD) has evolved from a vague concept into a somewhat coherent development framework. In the Brundland report sustainable development was defined as: “development that meets the needs of the present without compromising the ability of future generations to meet their own needs”.

Few visitors can travel around Iceland without being deeply touched by its sheer beauty, and few can leave the country without a strong vow to return. It’s just that sort of place. Perched on the edge of the Arctic, this wonderful little island contains some of the most impressive natural wonders in Europe. The continent’s biggest waterfalls thunder down with such force that the ground trembles under your feet; the barren highlands form Europe’s largest, loneliest desert; and the awesome ice cap Vatnajökull is the biggest outside the poles. Other spectacular phenomena include smoldering volcanoes, slow-flowing glaciers, extruding lava, gushing geysers, bubbling mud pots, soothing thermal pools and, in the darkness of winter, the magical northern lights.

  • Direct Utilization of Geothermal Energy 2020 Worldwide Review
    Proceedings World Geothermal Congress 2020 Reykjavik, Iceland, April 26 – May 2, 2020 Direct Utilization of Geothermal Energy 2020 Worldwide Review John W. Lund1 and Aniko N. Toth2 1Geo-Heat Center, Oregon Institute of Technology, Klamath Falls Oregon, USA 2Ana-Geo Ltd., Miskolc, Hungary [email protected], [email protected] Keywords: Geothermal, direct-use, spas, balneology, space heating, district heating, aquaculture, greenhouses, ground-source heat pumps, industrial application, snow melting, energy savings, wells, drilled, manpower, investment ABSTRACT This paper presents a review of the worldwide applications of geothermal energy for direct utilization and updates the previous survey carried out in 2015. We also compare data from WGC1995, WGC2000, WGC2005, WGC2010, and WGC2015 presented at World Geothermal Congresses in Italy, Japan, Turkey, Indonesia and Australia. As in previous reports, an effort is made to quantify geothermal (ground-source) heat pump data. The present report is based on country update papers received from 62 countries and regions reporting on their direct utilization of geothermal energy. Twenty-six additional countries were added to the list based on other sources of information. Thus, direct utilization of geothermal energy in a total of 88 countries is an increase from 82 in 2015, 78 reported in 2010, 72 reported in 2005, 58 reported in 2000, and 28 reported in 1995. An estimation of the installed thermal power for direct utilization at the end of 2019 is used in this paper and equals 107,727 MWt, a 52.0% increase over the 2015 data, growing at a compound rate of 8.73% annually. The thermal energy used is 1,020,887 TJ/yr (283,580 GWh/yr.), a 72.3% increase over 2015, growing at a compound rate of 11.5% annually.

There are of course, many reasons for this development, but our renewable energy resourc- es – used in a sustainable manner – have played an important role. As a result electricity generation in Iceland is entirely from domestic energy resources, and nearly all buildings are heated with domestic energy, mainly geothermal heat. Today, approximately 71% of the country’s total primary energy is renewable energy, which is unique in the world. Nevertheless, the aim is to improve on this figure with the long-term goal of Iceland becoming self-sufficient for all its energy needs, using its own renewable resources.

It is direct use, power generation estimated that the total direct heat uses of geothermal energy in Iceland in 1999 was 20,170 TJ and the corresponding installed ABSTRACT capacity 1,469 MWt. Geothermal energy plays an important role in the energy The availability of geothermal energy has influenced strongly supply of Iceland. It provides about 50% of the total primary the standard of living in Iceland. The economic benefits of energy supply while the share of hydropower is 18%, oil 30% using geothermal energy for space heating instead of fossil and coal 2%. The principle use of geothermal energy in Iceland fuels are significant, as it saves annually about 100 million is for space heating; about 86% of all energy used for house US$ in imported oil. Besides financial savings the heating comes from geothermal resources. The share of environmental benefits are of great importance. It has been geothermal heating is still slowly growing. A recent estimated that house heating by fossil fuels would cause development is a 7 MWt district heating scheme for the village release of CO2 to the atmosphere of the same order of Stykkisholmur which started operation in 1999. magnitude as the total release of CO2 by human activity in Iceland today (Palmason, 1997). An expansion in the energy intensive industry in Iceland the last years has increased the electricity demand considerably. 2.
