Kvasir Technologies

Kvasir is solving one of the most difficult problems in the world; how to replace fossil fuels in the heavy transportation industries. Kvasir has developed and patented a unique process to convert ligno-cellulosic plant biomass (straw, wood, bagasse etc. ) to marine fuel in a simple one step process. The process involves cooking biomass in an alcohol atmosphere under pressure, effectively liquefying the biomass. Were developing our technology in our in-house lab and workshop facilities in Soeborg and are also collaborating with universities in both Denmark and abroad.

Amalo

Our aim is to make the transition from fossil heating to sustainable heating as easy and profitable as possible for private homeowners. At Amalo, we understand that integrating renewable energy solutions is key to achieving this goal. That's why, in addition to our focus on sustainable heat pump solutions, we also offer high-quality solar panels. This addition enhances our commitment to a greener future and provides a more comprehensive approach to energy efficiency for our customers. Our way to achieve this goal is to provide a market-leading user experience from initial customer contact to when we install a sustainable heat pump solution in the customer's home. The integration of solar panels into our offerings aligns perfectly with this vision, ensuring that our customers have access to a wider range of sustainable energy options. What is unique about Amalo is that we provide a full online customer experience. We have emulated the traditional physical visit at the customer's address through an online configurator. This innovative approach not only means we can offer more economical heat pump solutions faster than any other provider but also allows us to efficiently incorporate solar panel solutions into our customer's energy plans. By doing so, we ensure that our customers receive a tailored, comprehensive approach to their energy needs, all from the comfort of their own home.

Hafnium Labs

We support chemicals, energy, and pharma companies by solving one of the biggest challenges in chemistry: Obtaining reliable physical properties fast Advances in chemistry change the world: From the drugs that save our lives, to the crops and energy solutions that will save our tomorrow. The world spends $350 billion annually on chemical R&D and new process plants to create a brighter future. But progress is limited by slow and expensive trial-and-error experimentation and legacy enterprise software, incapable of incorporating state-of-the-art research and compute power. We want to change that. Using technologies such as quantum chemistry and probabilistic machine learning, we have developed a set of breakthrough digital tools that help energy, chemicals and pharma companies develop greener products and more sustainable processes.

Klimate

We are devoted to accelerating the development and adoption of technologies that can help fight climate change by actively removing CO2 from the atmosphere. The challenge We are emitting 50 Gigatons of CO2 every year, and that needs to be reduced by at least 80%. However, that still leaves 10 Gigatons of CO2, and we need to get all the way to zero. Trees are great, but we need many more solutions as well if we are to get to zero. Currently, most of these are way too expensive (and limited in capacity) for companies to use. We've developed a platform that combines methods and makes it available to every company that wants to compensate their emissions. We work with cutting edge technologies, including Direct Air Capture, Bio char, Bio oil etc.

CELLUGY

United Nations Youth Association(UNYA) Denmark

UNYA Copenhagen is a volunteer-driven youth organization dedicated to empowering young people to engage with global challenges through the lens of the United Nations’ values and the Sustainable Development Goals. We create an inclusive platform where students and young professionals can learn, collaborate, and take action on issues like climate change, social inequality, peacebuilding, and innovation. We are addressing a clear and growing problem i.e. the disconnect between youth and global institutions. Many young people in Denmark care deeply about sustainability and justice but find it difficult to access meaningful opportunities to participate in international dialogue or contribute to real-world impact. This gap leaves motivated individuals without a channel to apply their energy, creativity, and ideas, while institutions miss out on fresh perspectives and engagement from the very generation that will inherit the future. UNYA Copenhagen bridges this divide by turning global ideals into local action. We organize interactive events, workshops, and panel discussions that make complex global topics accessible and relevant. Our activities are co-created by volunteers from diverse academic and cultural backgrounds who bring their own insights to the table. Through collaboration with universities, NGOs, and public institutions, we connect youth directly with experts and decision-makers, fostering a sense of shared responsibility and agency. What makes UNYA Copenhagen unique is our grassroots approach. We are not just an organization — we are a community that thrives on collective energy and creativity. Every project is designed by young people for young people, ensuring authenticity, inclusivity, and long-term motivation. Our strength lies in our diversity and the genuine commitment of our volunteers, who bring the UN’s global mission to life in a way that feels personal and actionable. The motivation behind UNYA Copenhagen is simple: we believe that youth engagement should not be limited to classrooms or conferences but should become a lived experience. We started this initiative because we wanted to make international dialogue tangible, local, and inspiring. Our team members share a passion for learning, community-building, and positive change — values that drive us to dedicate our time to building something meaningful together. Today, UNYA Copenhagen continues to grow as a platform where ideas turn into impact. We are seeking motivated individuals who want to gain experience in leadership, communication, and project management while contributing to a global cause. By joining The Hub’s Community Program, we hope to reach more passionate volunteers who want to be part of a dynamic network that connects Copenhagen’s youth with the world.

Ebbefos Holding A/S

**Ebbefos** gør den grønne omstilling til en realitet ved at gøre energioptimering enkel, intelligent og værdiskabende. Energiområdet bliver stadig mere komplekst. Svingende elpriser, øget elektrificering og nye teknologier gør det vanskeligt for både virksomheder og private at udnytte deres energiinvesteringer optimalt. Mange løsninger fungerer isoleret, hvilket betyder, at kunderne ikke opnår det fulde økonomiske og klimamæssige potentiale. Hos Ebbefos kombinerer vi intelligent energistyring med levering af strøm og markedets bedste energiteknologier. Vi integrerer elaftaler, batterier, solceller, elbilopladning, varmepumper og energistyring i én samlet løsning, hvorigennem energien købes, produceres, lagres og anvendes på det mest optimale tidspunkt. Resultatet er lavere energiomkostninger, bedre udnyttelse af energien og en mere robust energiforsyning. Vores mål er at være den betroede partner, der gør den grønne omstilling enkel og skaber målbare resultater for virksomheder, den offentlige sektor og private hjem. Ebbefos er ejet af en fond, og vores overskud går til indsatser, der styrker børn og unges trivsel. Derfor bidrager vores kunder ikke kun til en grønnere fremtid, men også til et stærkere fællesskab for kommende generationer. Vi tror på, at den grønne omstilling lykkes bedst, når teknologi, økonomi og samfundsansvar går hånd i hånd.

Flowering.dk

Flowering is a Copenhagen flower concept built on a simple idea: Fewer choices. Better flowers. We don't believe in hundreds of nearly identical bouquets. That's why we offer a carefully curated range, where every bouquet is thought through from start to finish. Every bouquet is made to order by our own florists and created for the person who will receive it. We don't make bouquets for stock, and we don't simply buy whatever happens to be available at the traditional flower market. Instead, we choose the growers and producers we work with ourselves, with a focus on quality, freshness and long-term relationships. Alongside the flowers, we offer a selection of gifts such as organic chocolate, wine and beer, making it easy to add a personal touch to a delivery. Our packaging is kept simple too. No cellophane. FSC-certified paper made in Denmark and string made from recycled material. Where it makes sense, we deliver by bike, and our routes are planned with as few kilometres as possible. All our employees are employed on Danish terms and conditions. Flowering for business Hundreds of companies use Flowering to send flowers and gifts to employees, customers and partners. We help with birthdays, anniversaries, welcome gifts, office flowers and larger send-outs to many recipients at once. Create a business account in 2 minutes at flowering.dk/flowering-b2b
