The SEK 2 million innovation challenge is back for another round. Are you ready to take on the challenge?

We are currently facing one of humankind’s biggest challenges ever. Anthropogenic emissions of greenhouse gases must be drastically reduced in order to limit global warming to 1,5 degrees and avoid causing irreversible damage to the planet we inhabit.

Are you ready to take on the challenge? Read on to learn more about how to join this year’s competition.


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 Past Winners.


Power Refinery

Flower operates a power refinery with the mission to drastically increase available flexibility in the power grid and support the renewable electrification of everything. Power refining is the process of making electricity adaptable, usable and available when it’s needed. With advanced software and algorithms, Flower’s technology performs power predictions, bidding optimization and stand-by active power control every hour of the day. Through their platform, they connect assets such as EVs, energy storage, solar panels, and heating with those in need of flexibility.

Ligna Energy

Green Energy Storage

Ligna Energy is a greentech startup company developing disruptive products for electrical energy storage. Green, scalable and cost-effective storage of electricity is a prerequisite for the transition to a society free from fossil energy. Ligna have created a bio-battery from forest materials based on organic electronic polymers and biopolymers, which are used throughout the lifetime of the energy storage and then recycled and burned as biofuel. Thereby, they maximize the utilisation of materials, enable fossil-free energy production and minimize the overall negative lifecycle impact.

Peafowl Plasmonics

Plasmonic Solar Cells

Peafowl Plasmonics is on a mission to commercialize the world’s first direct plasmonic solar cell for optimizing energy use in buildings. Buildings account for 36% of CO₂ emissions globally. In response to this, Peafowl have developed a printable, fully transparent solar cell that can be integrated into sensors as an invisible and scalable power solution. This allows smart building technology to be implemented in existing buildings in a non-intrusive way, enabling increased sustainability in buildings without compromising living standards.

Enjay Systems

Energy Recovery

Enjay is a Swedish greentech company specialized in energy efficiency in hostile environments. Their innovation, Lepido, is a heavy-duty heat exchanger that is able to recover energy in polluted airstreams where existing technologies are unable to operate. It makes energy recovery in difficult environments, such as restaurant kitchens, not only possible, but profitable. The innovation enables reducing annual CO₂ emissions by 500 million metric tons, equal to one percent of the projected world-wide CO₂ emissions by 2050.
