Auxilium Infrastructure Partners

Auxilium Infrastructure Partners develops, owns, and operates flexible energy assets that help stabilize the electricity grid while creating new revenue streams for industrial sites and asset owners. The electricity system is becoming increasingly volatile as more wind and solar power enter the grid. This creates a growing need for fast, reliable flexibility: assets that can consume, store, or release power when the grid needs support. Today, many industrial sites have unused grid capacity, heat demand, backup systems, or space for batteries, but lack the technical platform, market access, and operational expertise needed to turn that flexibility into revenue. Auxilium solves this by combining physical energy infrastructure with proprietary software. We deploy and operate assets such as battery energy storage systems, electric boilers, load banks, and other controllable loads. Our platform connects these assets to energy markets and ancillary service markets, allowing them to support grid stability, optimize power consumption, and generate income. We handle the full process from site assessment and technical design to installation, operation, market participation, monitoring, and optimization. This gives customers a simple way to monetize their grid connection or energy assets without needing to build their own trading, control, or compliance capabilities. Our mission is to accelerate the green transition by making distributed energy flexibility scalable, investable, and easy to deploy.

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.
