Pioneering thermal energy storage for a sustainable tomorrow

Long term investment

At Grensle, we believe that sustainable growth is the foundation of long-term value creation. By investing in solutions that are both economically viable and environmentally responsible, we aim to deliver strong returns while contributing to a more resilient future.

Vision

Being self sufficient – by bridging the gap

It began with a simple but ambitious idea – to store renewable energy for when it’s really needed. A vision about being self sufficient from wind- and solar power all year around. We saw the challenge: hydro, wind and solar produce more power than the grid and consumers can handle at certain times, but still not enough during peak demand. Our goal was to bridge that gap – and that’s how Grensle was born.

Mission

Saving renewables

Grensle specializes in large-scale mineral energy storage with the mission “Saving renewables.” The technology stores surplus energy from summer to winter and enables more renewables in Europe’s grids, making green energy and district heating profitable again. With strong investor backing, Grensle leads the development of large-scale, mineral-based energy storage across Europe.

Goal

Global leader

Grensle is raising growth capital to build and finance Europe’s first large-scale mineral energy storage facilities for district heating owners. This approach minimizes customer risk and accelerates rollout. Each year, Grensle scales up tenfold, aiming for five commissioned sites within five years and over €1 billion in revenue with a 20% profit margin within a decade.

Business plan

Our overall ambition is to be a leading producer of mineral energy storage and energy supplier, providing our products and services to large heating consumers in Northern Europe. With a position of strength, we will achieve this by accelerating our investments in sales, technology development and intellectual property. This will enable us to continue to create long-term value for our shareholders.

As outlined in our 2030 roadmap, we will focus, reassess and invest in the following four key areas going forward: Accelerating R&D with intellectual property rights, scaling the product to commercial scale, strategic partnerships and efficiency improvements. The 2030 strategy defines what we want to achieve to future-proof our business and accelerate our revenue growth potential.

Our ambition is to accelerate revenue growth and increase our profitability. We see both revenue and profitability as we reach full commercial scale with our product and associated services. Increased efficiency and profitability can be demonstrated through geometric models and physical fundamentals. Our profitability ambition will continue to guide us going forward.

Financing of Grensle's energy storage at the customer's premises

The facility is built next to the district heating network to minimize heat losses and connection costs. The district heating operator can choose between two financing options for the energy storage:

Option 1: Grensle finances, builds and owns the energy storage facility. The district heating company buys heat at an agreed cost, with the option to buy the facility from Grensle at a later stage. This will be the option that Grensle advocates for customers during the first five-year period. The option burdens Grensle’s cash, which is why the company needs to raise large amounts of external capital.

Option 2: The district heating company finances and owns the energy storage facility. Grensle takes care of construction, commissioning and maintenance through a long-term service agreement. When the technology is scaled up and Grensle sees that many customers want to own the energy storage themselves, this option will also be offered.
