ReFlow - GreenTech for shipping

ReFlow is on a mission to support the decarbonization of the maritime industry. We are building a brand-new platform from scratch, designed to empower stakeholders with the tools and insights needed to drive sustainable change. We have a fun and social atmosphere, with an amazing location in the center of Copenhagen—right next door to the King and Queen!

KiteX

At KiteX, we're revolutionising energy with innovative wind turbines inspired by kites. Our mission? To make wind turbines that use significantly less material, offering a cost-effective and sustainable alternative to traditional turbines. Our journey began by envisioning wind turbines that combine the efficiency of kites and autonomy of drones. On this path we found an hybrid design with guy wire supported tower and blades could achieve almost the same material savings, but without any of the disadvantages. Our unique approach centres on patience, refining technology step by step, and focusing on sustainable solutions. We're scaling up production of the groundbreaking Wind Catcher, a portable off-grid turbine, while designing a larger, grid-connected successor. As we grow, we're seeking exceptional team members in marketing, customer support, technical, and electrical engineering. KiteX isn't just a workplace; it's an opportunity to drive clean energy and make history. Join us in shaping a sustainable future. Contact us through the hub or at info@kitex.tech to be part of something extraordinary.

KRING

We are a venture studio and we are a family of impact funds. We partner with incredible entrepreneurs & corporates to co-create solutions that have a positive impact on society and the planet. We have our own investment fund that enables us to execute fast and focused with co-founders and strategic partners.  We focus on building ventures within health & well-being or energy.  Our team is small and experienced and our network is big and powerful. We are a super ambitious bunch and perhaps some people would consider us crazy. We meditate with brain scanners, we discuss various tests for optimal health, and wonder why the human race is destroying the earth and if in the future an AI would put the human race under administration. However, we want to take part in ensuring that humans actually are a force for good, for each other, and toward this beautiful planet. We start with ourselves: We have weekly runs, CrossFit in the park, healthy eating, sustainable sessions, and of course also the normal casual talks and loads of fun.

ZynexGroup

ZynexGroup is a Danish company based at Incuba, Åbogade 15, Aarhus. We place a customer-owned battery cabinet (BESS) at factories and industrial sites that already have a grid connection (existing 400 V AC three-phase). ZynexGroup operates the battery in the ancillary services market – frequency regulation that helps keep the power grid stable – and the customer gets paid. Because the battery uses the existing connection, the project does not have to join Energinet's queue for new grid connections, unlike stand-alone battery parks. Hybrid Greentech is the balance responsible party (BRP) partner. CVR 45624013. The problem: Denmark needs far more flexible capacity to balance a grid with more and more wind and solar, but new grid connections for battery parks are stuck in long queues. ZynexGroup unlocks capacity that already exists on industrial sites, so batteries can start delivering grid services sooner and industrial companies earn from infrastructure they already have.
