What Ligna Energy does
Ligna Energy AB is a Swedish developer and manufacturer of ultra-thin, bio-based supercapacitors designed to enable battery-free operation in IoT devices, smart cards, and wireless electronics. Founded in 2018 in Norrköping, Sweden, the company originally pursued large-scale 'wood batteries' for grid energy storage before pivoting in 2021 toward thin-form-factor supercapacitors for connected electronic devices. The company is privately held, employs approximately 10 people, and is led by CEO Peter Ringstad with CTO Jakob Backe and Chairman Hans Hentzell.
The company's core technology uses lignin extracted from Swedish forest industry waste, processed through a proprietary roll-to-roll manufacturing method into electrochemical double-layer capacitors (EDLCs) marketed under the S-Power series. Current products include the S-Power 2S (1.2F, 2.7V, lower internal resistance for energy harvesting integration) and S-Power 2R (50mF, 0.4mm thick, designed for smart cards and RFID). The technology offers 100,000+ charge-discharge cycles, contains no heavy metals, PFAS, or REACH SVHC substances, and carries a third-party verified carbon footprint of 12 g CO2e per unit with approximately 78.5% material recoverability at end of life. Production capacity stands at 100,000 units per year at the Norrköping facility, with full contracting for 2026-2027.
Ligna's business model centers on hardware sales through four parallel channels: direct enterprise sales to OEMs and IoT device manufacturers (managed by Sales Director David Milton), global marketplace distribution via DigiKey, regional channel partnerships (OEM Electronics in Sweden), and OEM embedded partnerships where S-Power components are integrated into customer products. The company has built a substantial ecosystem of technology integration partners including ONiO (batteryless microcontrollers), e-peas (power management), Epishine (organic photovoltaic cells), Nexperia (PMICs), and NeoCortec (low-power radio). Named customers include Displaydata (electronic shelf labels), TrustSEC (smart access cards), Taggr (asset tracking), and Signostium (smart building displays). Revenue is not publicly disclosed; the company has raised approximately €4.7M in equity capital and €5.5M total including grants from Vinnova, EU Eurostars, and the Swedish Energy Agency.

Ligna Energy product offering
Product offeringCore offering
Ligna Energy manufactures and sells the S-Power series of ultra-thin, bio-based supercapacitors made from lignin (a forest industry waste material) for integration into IoT devices, smart cards, electronic shelf labels, and asset trackers. The supercapacitors are produced via a proprietary roll-to-roll process at the company's Norrköping facility and are designed to enable battery-free operation when paired with energy harvesting technologies. The portfolio includes the S-Power 2S (1.2F compact supercapacitor) and S-Power 2R (50mF ultra-thin pouch at 0.4mm thickness for smart cards and RFID).
Product overview
Ligna Energy offers the S-Power series of ultra-thin, bio-based supercapacitors designed specifically for wireless electronics and IoT applications. The product line centers on the S-Power platform with multiple variants: the S-Power 2S (1.2F capacity for general IoT use) and S-Power 2R (50mF ultra-thin variant for smart cards and RF applications). Both products leverage forest-derived materials from Swedish forestry waste, particularly lignin, and are manufactured using proprietary roll-to-roll production at the company's Norrköping facility. The supercapacitors are designed to integrate with energy harvesting technologies (light, RF) to enable maintenance-free, battery-free IoT devices. The company also provides the Gwen reference design demonstrating battery-free indoor climate sensing as a template for OEM partners.
