10 hottest cleantech startups in Europe

From extending battery life to make value out of wood waste, ten cleantech startups pitched their ideas to tackle the climate crisis at this year’s Slush.

This year’s Slush was all about changemakers and the oncoming sustainable revolution. While a lot of startups attending the two-day conference had the potential of making a change, ten cleantech startups were selected to pitch on stage for a jury of four at the Climate Impact Battle; ten startups that according to Climate-KIC have the potential to become leaders in addressing climate change.

Adaptive Balancing Power

This German company founded in 2016 is all about energy storage. They have developed a flywheel energy storage solution as an upgrade to existing power generation assets together with its own grid balancing software.

Adaptive’s solution is low cost, sustainable, scalable, and has an unlimited cycle-life making it an innovative energy storage system and a new business model for stabilizing electricity grids. In 2018, Adaptive will build Europe’s largest Flywheel installation.

Brill Power

This battery systems startup targets the market for grid-scale energy storage. Their battery control and management technology will ensure full utilization of each cell in the battery pack extending the cycle life of a multi-call Lithium-ion battery by up to 60 percent.

Their first product is a printed circuit board supported by specialized battery control software. Located in Oxford, the startup consists of four full-time employees and have raised 120.000 £.

Trucks on the Map

The winner of the Impact Climate Battle and the 50.000 euro helps logistics professionals to reduce empty miles and risks significantly with an easy to use online-map and social medium.

According to Trucks on the Map, 12-27 % of the long-haul truck journeys are run empty hitting 120 billion kilometers of deadhead trips a year in the EU and the US. With Trucks on the Map, trucking professionals and shippers can check live where there are free bookable trucks at any future time, anywhere on the globe.

Trucks on the Map have been developing the product since 2014 and launched the official system in May 2017.


AquaRobur is a Swedish invention that detects water leakages and support renewal of public water pipeline networks via self-powered sensors.

The product is placed various places along the water pipeline to detect flaws, water pressure, and deviations, and a small part of the energy of the flowing water gets transformed into electricity by a patent-pending technology. The sensors can collect real-time data during a long time – 8+ years – which is a lot longer than battery-powered solutions that run for a couple of months with a similar setup.


This Dutch company founded in 2015 promises better batteries through nanocoatings. Delft-IMP has developed a coating for inexpensive battery materials that can enhance the lifetime of the batteries and make them suitable for use in automotive applications. Delft-IMP promise that their patented equipment effectively decreases the costs for lithium-ion battery manufacturers by a factor 5. After establishing themselves in the battery market, Delft-IMP plan to expand to fuel cell and lighting applications.


Trunkrs works in the e-commerce space. Through crowd-funding and business angels, Trunkrs have raised 385.000 euros for their smart solution for webshops.
