Ørsted Propel selects its first startups

Amsterdam, February 2, 2023: Rockstart and Ørsted  announce that the first startups for the Ørsted Propel acceleration program have been selected. The two organizations have teamed up and launched Ørsted Propel in 2022 to accelerate startups with the potential to revolutionize the energy sector as part of the new Ørsted Innovation Hub. The four-month open innovation program will further support growth for the selected startups, providing funding opportunities, resources to develop pilot projects, and other long-term engagements with Ørsted. 

Utilizing Ørsted’s vast network and industry knowledge, Ørsted Propel is designed and implemented by Rockstart and focuses on solutions for electricity system integration as part of Ørsted’s new Open Innovation Hub in the Netherlands. The program starts in February 2023.

The first eight selected startups were chosen from a pool of more than 150 applications from 30+ countries and cover a wide range of energy solutions. Of the eight selected startups, several put forward solutions and strategies to optimize energy storage like Cactos, Geyser Batteries, phelas, suena, and RFC Power. Think RE focuses on strategies for decarbonization while Ocean Swell Energy develops floating power generator vessels. Real Carbon Tech offers C02 conversion for industrial sites and beyond.

‘The Ørsted Propel program is a unique program in which we combine the potential of startups and Ørsted’s experience in the renewable energy market. It is through corporations like this that we can work towards a more integrated energy system. By supporting innovations and testing technologies, Ørsted aims to create a world running entirely on green energy. I want to congratulate the eight participants and look forward to our future cooperation’  Ruben Dijkstra, Managing Director Ørsted Benelux
We at Rockstart are excited to welcome the first eight startups selected to participate in Ørsted Propel. The innovative solutions put forward by their founders have the potential to significantly optimize our energy system during a time when cost and access to renewable energy are some of the most critical factors from a geopolitical and macroeconomic perspective. We are proud to collaborate with Ørsted to further push for a greener and more sustainable energy system. Rune Theill, CEO & Co-Founder, Rockstart
