Abstract [en]

Alternative solutions, instead of building new transmission lines, are needed to enable the fast electrification of sectors such as industry, transportation, and heating. This includes smart-grid technology allowing for an increase in hosting capacity without the need for building new transmission lines. The increase in hosting capacity beyond the firm hosting capacity is, with many of the schemes, related to the ability of the installation to tolerate curtailment. The paper gives an overview of different smart-grid schemes and how they potentially increase the hosting capacity. The connection of a large electrolyser installation for hydrogen production is used as an illustrative example introducing some of the issues.

Vätgas, energisystem och infrastruktur i norra Skandinavien och Finland − förstudie
Abstract [sv]

Denna förstudie har genomförts av RISE Research Institute of Sweden och Luleå tekniska universitet tillsammans med ytterligare 24 aktörer verksamma inom vätgasenergisystem i norra Sverige. Aktörer och planerade investeringar har kartlagts via intervjuer inom och utanför projektkonsortiet, och tekno-ekonomiska samt regulatoriska analyser har genomförts. Studiens syfte var att analysera förutsättningar, möjligheter och hinder för en vätgasinfrastruktur i norra Skandinavien och Finland. Studien har gett en uppdaterad bild av nuläget och av de projekt som planeras i regionen, och det befintliga och kommande regelverket för vätgasvärdekedjan har summerats. Vidare har en tekno-ekonomisk analys av vätgasledningar och konsekvenser för elnätet genomförts, samt SWOT-analyser för de olika alternativen. Slutligen har ytterligare forskning och aktiviteter som krävs för att komma vidare mot ett energisystem med vätgas föreslagits. Resultaten visar att elnät och vätgasledningar kan komplettera varandra på ett energi- och kostnadseffektivt sätt. Huvudslutsatsen är därför att stora och snabba satsningar bör fokuseras på att utveckla ett hybridsystem för att undvika onödiga inlåsningseffekter. Flera luckor har identifierats i dagens lagstiftning, därför rekommenderas en utredning av lagstiftningen kring vätgassystem. Vidare krävs en mångdubbling av ny förnybar elproduktion i elområde 1 för att täcka behoven som förutspås i industrin.

Abstract [en]

This prestudy has been carried out by RISE Research Institute of Sweden and Luleå University of Technology together with additional 24 stakeholders active in a hydrogen energy system in northern Sweden. Actors and investments have been mapped via interviews within and outside of the project consortium, and techno-economic and regulatory analyses have been carried out. The purpose of the prestudy was to analyse the conditions, opportunities and obstacles for a hydrogen infrastructure in northern Scandinavia and Finland. The study has provided an updated picture of current status and projects planned in the region, and existing and upcoming regulations for the hydrogen value chain have been summarised. Furthermore, a techno-economic analysis of hydrogen pipelines and consequences for the electricity grid has been carried out, as well as SWOT analyses. Finally, the study has suggested further research required to progress towards a hydrogen energy system. The results show that the power and hydrogen grids can complement each other in an energy and cost-effective way. The main conclusion is therefore that great and accelerated efforts should be focused on developing a hybrid system to avoid unnecessary lock-in effects. Several gaps have been identified in today's legislation, hence, an investigation of the legislation surrounding hydrogen systems is recommended. Furthermore, a multi-fold increase in new renewable electricity generation is required in electricity zone 1 to cover the projected needs of the industry.

Vehicles powered by alternative fuel : opportunities and barriers from the perspective of the public, media and stakeholder´s perspectives
Abstract [sv]

I detta projekt ingick tre olika delstudier med syfte att tillhandahålla en fördjupad förståelse för användarnas behov av och inställning till bilar som drivs med alternativa drivmedel såsom, el, vätgas och biogas. Förutom detta undersöktes inställningen till bilar och klimatfrågor i allmänhet men också vilka förutsättningar man ser för olika bilar med alternativa drivmedel. De olika studierna använde sig av tre olika metoder; fokusgrupp, enkät och intervjuer. I fokusgrupperna ingick sex personer. I enkätstudien deltog 487 slumpmässigt utvalda trafikanter och i intervjustudien nio aktörer från myndigheter, branschorganisationer och media. Resultaten visar att vid köp av bil är säkerhet och tillförlitlighet viktigare än utsläppen av CO2. Synen på bilar som drivs med alternativa drivmedel (elbil, bränslecellsbil, biogasbil), skiljer sig inte markant åt. Priset man är villig att betala för en sådan bil är betydligt lägre än vad dessa bilar kostar i nuläget. Rent allmänt kan man hävda att konsumenterna vill att en bil som drivs med alternativa drivmedel liknar eller är bättre än en konventionell bil. Studien visar också att politiker har en avgörande roll för hur utvecklingen av framtida alternativa drivmedel och infrastruktur för sådana ska kunna utformas. Enligt de intervjuade är det största problemet inte tekniken utan hur man ska få till stånd en infrastruktur för dessa fordon, och att de kommer ut på marknaden. Näringslivet är en viktig aktör som är villiga att satsa om de kan se att verksamheten kan bli lönsam. Långsiktighet är ett nyckelord som nämns både då det gäller politiska beslut och informationsspridning. I det senare fallet eftersom studierna visar att det finns stora brister i kunskapen hos allmänheten samtidigt som det finns en misstro mot den information som sprids. Slutligen visar studierna att det behövs ett helhetsgrepp där fokus inte enbart ligger på bränslen utan även utvecklandet av attraktiva och tillgängliga städer.

Abstract [en]

This project included three different studies with a view to providing an in-depth understanding of user needs and attitudes to alternative fuels and vehicles, such as: battery electric vehicles, hydrogen vehicles and cars using biogas. In addition the studies also examine attitudes to cars in general and climate change as well as exploring likely prospects for such cars in the future. The studies used three different methods; focus group, survey and interviews. The focus groups included six people, the survey 487 randomly selected road users and the interview study nine different stakeholders from government agencies, industry, branch organizations and the media. The results show that when purchasing a car safety and reliability are more important than the emission of CO2. The perception of cars powered by alternative fuels (electric, fuel cell, biogas), does not differ markedly. The price people are willing to pay for such a car is significantly lower than what these cars cost at present. In general, it could be argued that consumers want a car powered by alternative fuels to be similar or better than, a conventional car. The interview study also shows that politicians have an important role to play in the development of alternative fuels and the related infrastructure. According to the interviewees, the biggest challenge is not the technology, but rather how to provide an infrastructure for these vehicles. The industry is an important player who is willing to invest if the business can be profitable. Long-term is a keyword and is mentioned both in terms of policy instruments and information dissemination. In the latter case, since studies show that there are large gaps in the overall knowledge and understanding by the general public as well as considerable distrust of information presently available. Finally, the results also shows the need for a holistic approach where the focus is not only on fuel, but also on the development of attractive and accessible cities which reduce transport demand and provide for increased transport efficiency.
