Størrelse

Omkring 400 ansatte globalt, med et spænd fra 330-600 i de seneste år (kilde: linkedin.com, apollo.io). En omsætning på cirka 1,084 milliarder SEK i 2021 med hurtig vækst gennem begyndelsen af 2020'erne (kilde: mfn.se).

Hvad de laver

Polarium specialiserer sig i lithium-ion batteri energilagringsløsninger med fokus på telekommunikation, kommercielle, industrielle og distribuerede energilagringsapplikationer (kilde: linkedin.com, polarium.com). Deres produktportefølje omfatter batterier, batteri energilagringssystemer (BESS) og energistyringssoftware med avancerede cloud-baserede optimerings- og virtuelle kraftværksfunktioner (VPP), integreret gennem nylige partnerskaber (kilde: mfn.se, polarium.com). For telekundekunder leverer Polarium pålidelige reservekraftløsninger til basestationer, mens kommercielle og industrielle kunder drager fordel af reducerede energikostnader, undgåelse af netopgraderinger og indtægtsgenerering gennem energiarbitrage og fleksibilitetstjenester (kilde: polarium.com, mfn.se). Deres konkurrencefordel ligger i kombinationen af ekspertise inden for batteriudvikling, modulært BESS-design og integreret kontrolsoftware, hvilket muliggør partnerskaber inden for EV-opladning, distribueret lagring og telekommunikationskraftsektorer (kilde: polarium.com, polarium.com).

Projekter og Erfaring

Polarium har opbygget en stærk kommerciel track record, især inden for energilagring til telekommunikation. Et bemærkelsesværdigt partnerskab med ATC Africa omfattede levering af tusindvis af energilagringsløsninger og etablering af en fabrik i Cape Town med en årlig kapacitet på over 300.000 batterier (kilde: mfn.se). Inden for den kommercielle og industrielle sektor gennemførte Polarium en 700 kWh installation for Lindberg & Son og implementerede et Energioptimeringssystem i 2024 for Grönlunds Plåt (kilde: polarium.com, polarium.com). De samarbejdede også med Telia om et pilotprojekt i 2022, der validerede smarte batteriløsninger til telekommunikationsnetværk, samt med Areim om en storstilet batteripilot i svensk erhvervsejendom (kilde: mfn.se). Derudover indgik Polarium et partnerskab med Kempower for at integrere deres BESS-teknologi med EV-opladningsinfrastruktur og dermed forbedre pålidelig strømfordeling (kilde: polarium.com).

Seneste Udviklinger

De seneste år har Polarium intensiveret sit fokus på distribueret lagring og EV-opladningsinfrastruktur. I januar 2025 indgik de et strategisk partnerskab med Stella Futura for at fremskynde BESS-udrulning i Nordeuropa, hvor modulære batterisystemer kombineres med cloud-baseret optimering og virtuelle kraftværksløsninger (kilde: polarium.com). I marts 2026 samarbejdede Polarium med VAROPreem om at levere intelligente lagringssystemer til hurtigladestationer i hele Sverige, hvor modulært BESS og energistyringssystem (EMS) funktionalitet adresserer nettilslutningsbegrænsninger (kilde: polarium.com). Virksomheden udnævnte også Jan Roschek som administrerende direktør for Tyskland i 2026, hvilket signalerer en udvidelse på det marked (kilde: polarium.com). Endvidere sikrede Polarium en aftale med RWE om at markedsføre mindst 50 MW og 135 MWh fra deres distribuerede batteriportefølje med start i slutningen af 2026 (kilde: polarium.com).

At Arbejde Der

Polarium tilbyder karrieremuligheder inden for en række discipliner, herunder batteriteknik, design af energilagringssystemer, batteristyring, software og energistyringssystemer (EMS), salg, projektlevering og regional forretningsledelse (kilde: polarium.com, polarium.com). Virksomhedens hovedkontor ligger i Stockholm, Sverige, med et yderligere kontor i Littleton, Colorado, USA, som understøtter globale operationer og regional kommerciel ekspansion (kilde: linkedin.com, polarium.com). Polariums arbejdskultur lægger vægt på ekspertise inden for intelligent energilagring, hvor hardware- og softwareinnovation kombineres med kundernes projektgennemførelse med fokus på telekommunikationskraft og distribuerede lagringsmarkeder (kilde: polarium.com).
