We have our winners!
Two startups take home the grand prize in Startup 4 Climate 2021, Northern Europe’s biggest energy innovation challenge. Get to know our winners and how they aim to speed up the energy transition below.

A big thank you to everyone who contributed to this year’s challenge, especially the startups that participated with their time and bright ideas.
The energy transition is ongoing. Stay tuned for Startup 4 Climate 2022, 

The winners.



Virtual Power Plant

Krafthem started in 2020 with their minds set to drastically increase available flexibility in the power grid to support the renewable electrification of everything. Through their virtual power plant, they create a platform that connects owners of EVs, energy storage, solar panels, heating and more, with those in need of flexibility. By applying the use of AI they are able to make smart improvements to an ever more decentralised energy system.

Through their innovation, they have made being part of the energy transition an exciting upgrade for consumers, combining an attractive, low effort offer for users while providing an essential service for keeping society’s electricity system working smoothly in an increasingly complex energy landscape.

Ligna Energy

Green Energy Storage

In order to create a sustainable energy system based on intermittent energy sources, we must find a solution for our energy storage needs. Ligna Energy is a company based in Norrköping with the mission to make energy storage sustainable. Although an essential part of the energy transition, batteries are often linked to harmful practices during the extraction of raw materials. 

By substituting conventional practices with bio-based materials from Swedish forests, Ligna Energy is paving the way for growing the energy storage segment at a minimum cost for the environment. Their innovation seeks out business opportunities across the scale, from small sensor-powered applications to large scale energy storage, including several key components of a future energy system: electrification, IoT and renewable energy sources.

The Challenge.

Startup 4 Climate is aimed at young companies with ideas that can speed up the energy transition and steer the development towards the global goal of 1,5-degree warming.

The energy transition encompasses initiatives that promote the switch from current energy and transport systems to solutions that are smarter, more efficient and have the ability to reduce humanity’s negative impact on planet earth.

This year, eight of the best submissions pitched their ideas to a jury of experts from the fields of entrepreneurship, energy, green technology and climate action. The two winning startups were granted a SEK 2 million prize to help catalyze their ideas and contribute to the energy transition.

The Win-win.

What’s in it for you?

By participating in Startup 4 Climate, contestants have the opportunity to pitch their ideas to our jury of experts. The final winners will share a prize of SEK 2 million, as well as 3 hours of coaching from a jury member, to help catalyze their ideas and contribute to the energy transition.

Participants will also have the opportunity to interact with two of Sweden’s most well-known energy companies, tap into their networks as well as be fronted on large social media platforms and news outlets.

What’s in it for GodEl & Ellevio?

As two of the Swedish energy market’s most well-known actors, we have a great responsibility in shaping the future of the sector. We want to promote the transition to a truly sustainable energy system, but we can’t do it alone.

Innovation and wide-spread engagement are key aspects for curbing the global climate crisis. Therefore we want to catalyze more actors and contribute to initiatives that can enable our common goals for a sustainable future.
