The Future of Wave Power in Sweden: a Comparison Between the Evolution of Wind Power and Today’s Situation for Wave Power (English)
Abstract [sv]

Sedan början av 1980-talet har el från vindenergi levererats till elnätet i Sverige, men sedan dess har vindkraften byggts ut och förbättrats tekniskt. 2013 stod vindkraften för cirka 7 % av den totala elkonsumtionen i Sverige. I takt med att intresset och behovet av förnybara energiresurser växer sig allt starkare har även forskningen kring möjligheten att utvinna energi ur vågorna tagit fart. Den första kommersiella vågkraftsparken i Sverige, Sotenäs, började installeras i början av 2014, där tekniken baserats på den forskning som bedrivits av Lysekilsprojektet sedan 2002. Potentialen för elproduktion från vågor längs Sveriges kuster beräknas vara 10 TWh per år vilket kan jämföras med Sveriges totala elproduktion på cirka 150 TWh per år.

Denna rapport syftar till att visa hur vågkraftens situation idag kan jämföras med vindkraftens utveckling. Den komparativa analysen används sedan för att dra slutsatser om vågkraftens framtida utveckling. De parametrar som har jämförts är den totala installerade effekten, den totala producerade elen, producerad el per installerad effektenhet, producerad el per viktenhet, installerad effektenhet per viktenhet, investeringskostnad per installerad effekt och investeringskostnad per producerad el.

Denna studie visar att vågkraft, i och med byggnationen av Sotenäs vågkraftspark, kommer att leverera lika mycket el som vindkraftverk gjorde i början av 1990-talet. Materialeffektiviteten per producerad el för vågkraftverken motsvarar de vindkraftverk som byggdes i början av 2000-talet. Med dessa resultat är det sannolikt att det kommer att ta cirka 20 år innan 7 TWh el per år kommer att levereras från vågkraft vilket motsvarar 70 % av den beräknade totala potentialen. Den producerade elen per viktenhet kommer sannolikt därtill att dubbleras under de kommande tio åren. 

Abstract [en]

Since the early 1980s, electricity from wind energy has been supplied to the grid in Sweden, but since then, wind power has been expanded and improved technically. In 2013, wind power accounted for about 7 % of the total electricity consumption in Sweden. Due to an increased interest and need for renewable energy resources, the possibility of extracting energy from waves is being further researched. The instalment of the first commercial wave power park in Sweden, located in Sotenäs, began in January 2014. The technology in Sotenäs wave power plant is based on research conducted by the Wave Power Project in Lysekil since 2002. The potential for generating electricity from waves along the coasts of Sweden is estimated to 10 TWh per year, which can be compared with the country's total electricity production of approximately 150 TWh per year.

This report aims to show how the situation of wave power today can be compared to wind power development. The comparative analysis is then used to draw conclusions about the future of wave power. The parameters that have been compared are; total installed capacity, total generated electricity, generated electricity per installed power unit, electricity produced per unit weight, installed power unit per unit weight, investment cost per installed capacity and investment cost per produced electricity.

This study shows that wave energy, as a result of the construction of Sotenäs wave power plant, will supply as much electricity as wind turbines made ​​in the early 1990s. The material efficiency per produced electricity for wave power stations correspond to the wind turbines that were built in the early 2000s. With these results, it is likely that it will take about 20 years before 7 TWh of electricity per year will be delivered from wave power. This is equivalent to 70 % of the total estimated potential. The electricity produced per unit weight is furthermore likely to double in the next 10 years.
