The World’s Most Innovative Clean Energy Start-Ups: the SET Award 2023 Finalists

The need to innovate to reach net zero by 2050 is beyond doubt. The good news: innovation in the energy sector is demonstrably working. The SET Award 2023 finalists represent the best in energy and climate tech from around the world. Ahead of the SET Tech Festival in Berlin, we take a closer look at their solutions.

In 2022, global CO2 emissions rose less than feared because clean energy offset the impact of greater fossil fuel use. The start-ups that SET champions are, in part, to thank for this. SET is therefore proud to announce the 15 best energy and climate tech start-ups for 2023. These start-ups represent the cutting-edge of energy technology and solutions available in the world right now. Together, they will pitch their innovations in front of a global audience at the annual SET Tech Festival on 28 March.

Gathered from a global pool of over 400 applicants across 63 countries, longlisted through stringent criteria and metrics, and then finally shortlisted by our expert international jury, this year’s applicants raised the bar once again. Some 83% of applicants were qualified to enter (our highest level since we began), with 22% of start-ups founded by women, and a majority of all applicants having women and gender-diverse employees in positions of management. 

“In the current energy crisis, the development of a stable and digital energy system is of central importance”, explains Andreas Kuhlmann, CEO of the German Energy Agency (dena). “This has consistently been demonstrated, including most recently at the Munich Security Conference last month. The SET finalists and, more broadly, the companies on the SET100 2023 longlist, are all contributing to the global energy system’s security through new digital business models. The SET initiative also helps track technological development across the years SET has run as well as highlighting the most important trends that will shape 2023.” 

Clean Energy & Storage

Energy Dome | Italy | 2019

Unlocking utility-scale, long-duration energy storage through the use of CO2, Energy Dome’s innovative battery uses CO2 and thermodynamics to store and dispatch electricity quickly and cost-effectively. The Italian start-up is a newcomer to the SET platform but is already making an impact: recently receiving support from the European Innovation Council, the young company was also just tapped to join the Cleantech for Europe’s Scale-Up Coalition, supported by Bill Gates’s Breakthrough Energy platform.

Granular Energy | France | 2021

The way that renewable electricity certification is managed and certified is changing to an ‘hourly certificates’ model. This is creating (and is known as) the 24/7 carbon-free energy market. Granular Energy, the French start-up that’s barely two years old, has created an innovative suite of software tools that provides utility companies with the means to effortlessly manage their energy certificates in this new, rapidly evolving arena.

Heatrix | Germany | 2021

Heatrix wants to competitively replace fossil fuels in energy-intensive industries by converting renewable electricity into storable, high-temperature process heat. Currently, no carbon-neutral, cost-competitive and easy-to-integrate solution exists – although this is changing. Heatrix’s innovative solution has the potential to decarbonise the majority of high-emission industries and processes, from pre-heating to calcination, heat treatment, sintering and pelletization.

Rondo Energy | USA | 2020

The Rondo Heat Battery captures renewable electricity, delivering low-cost, zero-carbon and continuous high-temperature heat for industry. In Rondo Energy’s own words, the solution is, in essence, a toaster that heats bricks, but which can charge and discharge energy for potentially 100 years (in contrast to lithium batteries which degrade, comparatively, a lot sooner). Though simple, the solution has the potential to be huge, helping to decarbonise heavy industries like steel, cement, aluminium and biofuels.
