Student Stories
Discover the inspiring journeys of student teams from around the world.
Powering through the freeze: Peer-to-peer EV charging
A holiday road trip turned into a nightmare when an electric vehicle battery died in the freezing Northeast China winter, resulting in a staggering 8,000 CNY rescue bill. This expensive lesson inspired the Yunhui Super Charger team to develop a system where cars can charge each other. Here is their story.
Turning invasive weeds into fuel for education
When a sudden policy shift made cooking fuel unaffordable for community boarding schools in Indonesia, the team behind BioGangs didn't just see a crisis—they saw a connection. By linking an invasive river weed to the desperate need for energy, they are turning environmental waste into a lifeline for education. Here is their story.
From local plantations to a future global movement
What started as a simple observation at university plantation drives in Karachi has grown into a vision for a global green movement. Meet the team behind Sairaab - a GSC project looking to connect citizens, organizations, and students to make their cities greener, one geotagged tree at a time. Here's their story.
About the challenge and how it works
The challenge is designed to move bold and innovative ideas to real-world solutions. It offers students support and visibility at every step, from early research and design to building, testing, and sharing their work worldwide.
Phase 1: Ignite
Late August - Early November 2025 | Deadline: November 10, 11:59 PM UTC
Team up, tune in, and design forward. Form your team, choose a theme, and explore problems through research and stakeholder engagement. Create your concept and submit your application.
Key Deliverables: Team registration, problem statement, solution concept, and early mockup
Phase 2: Build
Late November 2025 - January / Early February 2026
Build, test, and showcase. Develop working prototypes, conduct user testing, and refine your solution. Present your progress at regional showcases with live demonstrations.
Key Deliverables: Working prototype, testing documentation, and 10-minute live presentation
Phase 3: Shine
February - April 2026
Refine and present at the Global Finale. Incorporate feedback, improve your solution's scalability, and pitch to a global jury. Top teams receive awards and ongoing support.
Key Deliverables: Final presentation, demo, and implementation plan for global impact
Guidance. Feedback. Community.
Behind every team is a network of mentors, judges, and peers who guide, challenge, and support the work as it grows.
Mentorship
Students can access general guidance and support from experienced professionals as they work on their projects.
Judging & Feedback
Projects are evaluated at multiple stages by a combination of expert judges and AI-supported review.
Regional Ambassadors
Ambassadors support outreach, coordination, and local connection. They help build regional networks, and ensure every team is seen and supported.
Beyond the Challenge
All teams benefit from new experiences, lasting connections, and a supportive community that continues after the challenge.
Annual themes provide a common focal point
Every team in the challenge chooses a theme — a broad area of work that grounds their project. Themes help focus the research and shape how teams define impact. This year, the challenge invites solutions in two key areas: Sustainable Energy, and Adaptation & Resilience.
Solutions Approach
Solutions should aim for real-world impact, right-sized to what a student team can meaningfully achieve in an academic year. We encourage participants to work across disciplines and contexts — technology, policy, finance, data, or even storytelling — to design solutions that are practical, responsive, and adaptable. The most compelling projects will demonstrate thoughtful design, stakeholder understanding, and a pathway to implementation that is both locally relevant and globally scalable.
Registration for the 2025-26 challenge is now closed
Subscribe for future opportunities →01 Sustainable Energy
Develop scalable and impactful solutions that reduce emissions while improving affordability and reliability in the energy sector. Solutions may address clean energy solutions covering generation, transmission, distribution, or storage.
02 Adaptation & Resilience
Develop a solution that enhances the resilience and ability of people, infrastructure, or natural systems to withstand and adapt to the intensifying impacts of climate change. Solutions may address disaster preparedness, resilient infrastructure, climate-smart agriculture, water security, or other critical adaptation needs.
