Abstract [sv]

En jämförelse mellan olika typer av mekanisk lagring av energi har gjorts. Nykomlingen Hydraulic Hydro Storage (HHS) har undersökts och ställts mot Compressed Air Energy Storage (CAES) och Pumped Hydro Storage (PHS) med avseende på verkningsgrad, kapacitet, kostnader och livscykel. De potentiella problemen som studerats hos HHS är seismisk stabilitet och tätningen. Analysen har gjorts genom litteraturstudie, beräkningar, intervju med grundarna Heindl Energy och kritisk granskning av deras information. Med den växande tillämpningen av förnyelsebar energi kommer problemet med lagringen av denna, varpå denna studie försöker besvara om HHS är ett komplement alt. substitut till framtidens energimarknad. Resultaten visade goda möjligheter att lösa problem med tätning och seismisk stabilitet. Jämförelsevis ställer sig HHS bra på verkningsgrad, livslängd, pris per MWh, och miljöpåverkan. På använd landyta och kapacitet presterar den mindre bra, men planerad kapacitet tros öka rejält under kommande decennier. Dessutom bedöms HHS kunna komplettera andra lagringsmetoder i en växande förnyelsebar energisektor.

Abstract [en]

A comparison between different methods of mechanical energy storage was made. The newcomer Hydraulic Hydro Storage (HHS) was evaluated and compared to Compressed Air Energy Storage and Pumped Hydro Storage (PHS) with respect to efficiency, costs, capacity, and lifecycle. Potential problems seismic stability and sealing were investigated further. The analysis was made thru literature study, calculations, interview with the founders and critical examination of their website and information. With the growing energy market comes the problems with energy storage, and our study aims to evaluate if HHS would complement the future energy market. The results showed good chances to solve sealing and seismic stability issues. Comparatively Hydraulic Hydro Storage excels at efficiency, lifespan, environmental impact and price/MWh. It performed average on capacity and area used although the former might see a substantial increase within decades. Additionally HHS is deemed to complement other mechanical energy solutions in a growing renewable energy market.
