Investment case

Azelio is a Swedish cleantech company with a bespoke and innovative long-duration energy storage system for renewable energy. We aim to power the evolution of a renewable society, by solving the urgent need for controllable and affordable clean energy.

1. A market driven by global demand for energy & a shift to renewables

Global demand for energy is increasing rapidly as the world is electrifying, and at the same time society must accelerate the transition from fossil fuels to renewables to keep global warming below 1.5°C. But renewable energy from intermittent sources, such as solar and wind, has limitations if it cannot be stored and used when it’s needed. Long-duration energy storage is the key to closing the 24-hour circle with clean energy. Estimates put the market for long-duration energy storage at $1 trillion in value by 2040.

2. An around the clock solution

Azelio solves the clean power transition with its modular TES.POD system that offers a cost-efficient and scalable long-duration energy storage, with no degradation in storage capacity over time. Energy from renewables is stored in the TES.POD as heat and is dispatched to a Stirling engine on demand – generating electricity and heat with up to 90% efficiency while also significantly outperforming both diesel and battery solutions in cost.

3. Sustainability at the forefront

Azelio’s TES.POD is charged with energy from renewable sources and has zero CO2 emissions. It uses recycled aluminum as storage media and responsibly sourced components from a European supply-chain. Compared to Li-ion batteries, the TES.POD has around 30% lower carbon footprint over its life cycle and no degradation in storage capacity. After its lifetime of 30 years, the TES.POD itself is highly recyclable, and the recycled aluminum core can be used again and again.

4. Platform for commercialization in place

Azelio’s business model as a technology provider for partners is to either sell TES.PODs directly to end-users or as an Energy-as-a-Service (EaaS) solution from a co-owned local project company. Production in volume design has been initiated at its manufacturing plant in Uddevalla, Sweden, previously owned by Volvo Cars. The first commercial orders have been signed and delivered, as Azelio intensifies its sales efforts with local presence and sales representatives on four continents.
