The research project Digitalized Node-trading with GO (DINGO) has been carried out in the period autumn 2018 to autumn 2021 in a collaboration between Becour AS, NORSUS, Stiftinga Vestlandsforsking, Norwegian University of Life Sciences, Østfold Energi, Zephyr AS, Lyse produksjon AS, Sariba AS and Turku School of Economics. DINGO has resulted in a digital meeting place for large producers of green energy and companies that want to tell the outside world that they use renewable energy. NORSUS has led the work packages related to system development and has used innovation and organizational research in its implementation. Systems thinking, which is also found in value chain analyses and LCA, has also been important in "breaking the code" with the complexity of the research challenges associated with building the matching algorithms between production and consumption of energy.

Norway is a world leader in electric cars. There is no other country where electric cars make up such a large share of new car sales as here. However, the fact that the electric car is emission-free in the use phase does not mean that the electric car itself is climate-friendly. When using Life Cycle Assessment (LCA), one can evaluate different fuels/technologies against each other in a holistic perspective. You can listen to Hanne Lerche Raadal, Head of Research, talk about LCA applied for electric cars at the #Klimakvarteret.

The #Klimakvarteret is a 15-minute digital lecture from a researcher on a topic related to climate change or climate solutions and is organized by the The Norwegian Climate Foundation .

"Power distribution with sustainability" will provide transmission system operators (TSOs) with a framework for the mapping and documentation of environmental sustainability, in the establishment, operation and maintenance of components, together with their dismantling for reuse or recycling.

This framework must be suitable for the production of both data and results for anything, from major, broad analyses of the energy system, to extremely detailed analyses and the selection, for example, of individual components in a transformer.

The project results will contribute to an overview for the TSOs, when identifying the relevant environmental challenges. This will enable them to develop strategies and set goals for their work on internal environmental sustainability.

There is an increasing requirement for the documentation of sustainability, both in the case of individual actors within the energy sector, and for the energy sector as a whole.

The framework must be capable of being used in communicating with customers, suppliers and the authorities. This will be achieved through the specific selection of robust and scientifically based indicators for the environmental and resource effects of the distribution grid.

As a result of this innovation, environmental sustainability will become an important component in the business management of participating TSOs. It will enable them to make changes in their distribution and transformation systems, and thus lead them in a sustainable direction.

The framework must also be suitable for use in the documentation of the overall sustainability of network operations in Norway.

Among the research questions the most important will be:

  • Which components in the network contribute environmental challenges relating to network operations?
  • How can land use and land changes be quantified, alongside the possible effects on biodiversity from the distribution of electricity?
  • Which environmental indicators with their associated calculation methods, are relevant in assessing the environmental impact of network operations?
  • How can these environmental indicators be employed in the strategy development of TSOs?

The results from the project will be in constant use in establishing the strategic goals of the TSOs, being implemented as assessment criteria in business management and strategy plans, as well as in the reporting of environmental and climate accounting.

The project manager is Energi Norge AS. Project leader Ketil Sagen.

R&D suppliers are NORSUS, NMBU and Geodata.

The transmission system operators participating in the project are: Agder Energi Nett AS, BKK Nett AS, Elvia AS, Lede AS and Tensio TN AS.

At the CIRED conference, Irmeline de Sadeleer presented some results from our joint research project with ABB Electrification Norway. We have performed carbon footprint assessment of a switchgear where we have used four different calculation methods. The results show that there are substantially variations across the studies, and we question how best to solve this challenge so that manufacturers and customers can produce and order the most environmentally friendly solutions.

The topic is considered so interesting that NORSUS by Anne Rønning has been invited to sit on the panel for a roundtable conference with the theme «Green Network Solutions».

ABB has published a video summarising our paper.

The project is funded by Oslofjordfondet.

Denne rapporten er en del av forskningsprosjektet Bærekraftig biogass, som er finansiert gjennom Forskningsrådets EnergiX-program.

Opprinnelsesgarantiordningen for elektrisitet er en europeisk ordning som er videreført og styrket i det reviderte fornybardirektivet (2018/2001/EU, ofte referert til som RED II). Ordningen inngår som en del av det felles rammeverket i det indre energimarked i EØS-området. Den ble innført med EUs første fornybardirektiv i 2001 for å gi forbrukere et prinsipielt valg. En opprinnelsesgaranti er et bevis på hvilke kilder en gitt mengde strøm er produsert fra. Ordningen ble innført med EUs første fornybardirektiv (Direktiv 2001/77/EC) i 2001 og er videreført i de reviderte fornybardirektivene (Direktiv 2009/28/EC og 2018/2001/EU). I henhold til EUs Eldirektiv (Direktiv 2009/72/EC) skal alle kraftleverandører informere sine kunder om hvordan kraften de solgte foregående år ble produsert. Dette kalles en varedeklarasjon.

I det reviderte fornybardirektivet av 2018 (RED II, Artikkel 19) er ordningen for opprinnelsesgarantier utvidet til også å omfatte gass (inkludert hydrogen), i tillegg til elektrisitet og varme/kjøling.

Den viktigste forskjellen mellom et opprinnelsesgarantisystem for elektrisitet (som eksisterer i dag) og for biogass, er bærekraftskriteriene med tilhørende krav til massebalanse, som kreves for bioenergi dersom den skal kunne inkluderes i et lands måloppnåelse for fornybar energi.

Det pågår et arbeid med å revidere CEN-standarden EN 16325 Guarantees of Origin related to energy – Guarantees of Origin for Electricity til også å omfatte gass, hydrogen, samt kjøling/varme, som antas ferdigstilt i løpet av 2022. Vurderingen av opprettelsen av et system med opprinnelsesgarantier for biogass bør derfor avventes og sees i sammenheng med dette arbeidet. I ovennevnte standard er det foreløpig lagt til grunn at det er frivillig å rapportere på bærekraftskriteriene.

Uavhengig av om det vurderes å innføre et opprinnelsesgarantisystem for biogass, anbefales det derfor å starte arbeidet med å utvikle en nasjonal database/register for flytende og gassformig drivstoff (jfr. RED II/artikkel 28), som inkluderer rapportering av bærekraftskriteriene. Det anbefales at dette arbeidet sees i sammenheng med tilsvarende arbeid som skal settes i gang i Sverige (Energimyndigheten, 2019a), som også har en større andel av sitt biogassvolum offgrid (leveres ikke inn på fells gassnett). I tillegg bør arbeidet med utvikling og oppretting av et slikt register samkjøres med det systemet som Miljødirektoratet i dag har for alle som omsetter biodrivstoff og flytende biobrensel om rapportering oppfyllelse av bærekraftskriteriene, og med dagens rapportering fra norske biogassanlegg til Miljødirektoratet og SSB. Resultatene fra dette arbeidet vil danne et viktig grunnlag for en vurdering av en fremtidig kobling av et slikt registeret til et eventuelt opprinnelsesgarantisystem for biogass.

Production of biogas from manure at a farm level is the very epitome of a sustainable bioenergy system. The system incorporates a circular economy decentralised production of organic biofertilizer and biogas for use in heat, power or transport fuel, whilst simultaneously reducing fugitive methane emissions from open slurry holding tanks, reducing smells and minimising pollution effects on rivers and wells. Why therefore is the practice of producing biogas from manure not more widespread? The characteristics of manure depend on farm animal source and the method of husbandry, which in turn leads to a wide range of levels of technically available manure resource and costs of biogas produced from manure. To exemplify this, IEA Bioenergy published this report which examines the potential of manure for utilization in biogas facilities across seven countries: Germany; Australia; Austria; Norway; Canada, Ireland and the UK. These countries have differing levels of biogas industry, very different farming practices and a range of climates. It is hoped that the country selection should allow the lessons learned from these seven countries to be applied to many countries across the planet.

This report is a delivery of the project Industrial CCS cluster at Øra and regionally, supported by CLIMIT.
The emission of greenhouse gases (GHG) from human activities is one of the most important environmental issues of the twenty first century. The largest source of GHG is carbon dioxide, which has increased tremendously in the last decades, mainly due to fossil fuels combustion for power generation and automotive transportation. CCS (carbon capture and storage) is a way of reducing greenhouse gas emissions by capturing and subsequently storing the carbon dioxide (CO2) permanently. CCU (carbon capture and utilization) represents a way of recycling the carbon in the captured CO2 by converting it to fuels or other products. The acronym CCUS describes systems including both utilization and storage of captured CO2.
This study has analysed systems for CCS (carbon capture and storage) and CCU (carbon capture and utilization) and compared these with their respective reference scenarios. The study has been carried out using Life Cycle Assessment (LCA) methodology according to the ISO-standards 14044/48 and guidelines provided for CCU value chains. The LCAs have been performed for two industrial cases: Norske Skog Saugbrugs, a paper production plant, and Sarpsborg Avfallsenergi (SAE), a waste to energy (WtE) plant
