The Challenge.

Startup 4 Climate is one of our most urgent initiatives to date. We believe that innovation and collaboration is key as we move into the future, which is why this challenge is aimed at young companies with ideas that can speed up the energy transition and limit global warming to 1,5 degrees.

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

The shortlisted submissions pitch their ideas to our jury of experts from the fields of entrepreneurship, energy, green technology and climate action. The winning startups are granted a SEK 2 million prize to help catalyze their ideas and contribute to the energy transition.

The Shortlist.

AirZyme Sweden

Biocatalysts for faster and more energy-efficient carbon dioxide capture

AirZyme has developed a biocatalyst that accelerates the process of capturing carbon dioxide while requiring less energy than existing methods. This results in reduced energy consumption, lower emissions, and decreased operational costs for carbon capture and storage.

Nordic Bio-Graphite

Fossil-free graphite

Graphite is the largest component in electric vehicle batteries and is also required for the production of “green steel.” NBG is the first to produce larger volumes of fossil-free graphite from bio-based materials. The graphite can be produced at competitive prices while significantly reducing CO2 emissions compared to current solutions, and it decreases energy consumption with the help of patentable new technology.

MaMa Växtkraft

Local collaborations for district heating

MaMa Växtkraft aims to increase energy efficiency in building heating by utilizing local resources, primarily wood chips, for district heating production. The project is based on a circular system where the local community collaborates to provide materials and reduce dependence on imported resources and long-distance transportation. The company has already successfully established a solution in Skurup and sees potential to scale the model to more municipalities through a franchise concept.

EvoShower

Circular shower reduces water and energy consumption by up to 90%

EvoShower is a circulating shower with a patented dual-loop system that saves up to 90% of water and energy consumption. The shower can be used independently of existing infrastructure and is easy to install in bathrooms without the need for professional installation – it is simple, time-efficient, and cost-effective. Additionally, it can be powered by solar panels in areas without established water and electricity grids.

ClimateHero

Carbon calculator to understand and reduce your carbon footprint

ClimateHero enables households and small businesses to calculate their carbon footprint, commit to reducing their carbon emissions, and contribute to solving the climate crisis. By answering a few simple questions about how they live, travel, and consume, the company helps individuals and businesses understand their carbon footprint and provides advice on how to reduce it. Winner of the People’s Vote.
