Challenges 2025
1. Grid & Green
Can we power the future without overpowering the planet? Join ČEPS at GreenHack 2025 and design innovative solutions that make energy infrastructure part of the natural landscape. Use tools like remote sensing, GIS, or AI to assess the environmental impact of today’s power grid and identify areas where sustainable transmission can grow in balance with ecosystems. Think long-term—your solution should hold up for the next 50 years. Leverage open data like Copernicus, CORINE Land Cover, ÚSES, ZABAGED, and more. Get exclusive access to datasets, expert mentoring from ČEPS, and a chance to shape the future of green energy.

2. Smart Trip, Efficient Choice
Design a system that plans employees‘ business trips in a smart, fast, and eco-friendly way. Combine data on shared cars, trains, and public transport, while factoring in emissions and time efficiency—and make sure it integrates with SAP. Add cost and CO₂ comparisons or gamification to motivate greener choices, and you might just create a tool that rewrites the rules of corporate travel.
Challenge partner: Mycroft Mind
3. Engage & Comply
How do we make complex environmental and sustainability standards truly stick?
Design a proof-of-concept solution that transforms regulatory frameworks, guidelines, and best practices into interactive, engaging learning materials. Think beyond static PDFs — bring them to life with testing, animations, and even virtual assistants that help users navigate and apply the content effectively.
Challenge partner: TESCO
4. NextGen Impact
Design a digital platform or game that empowers high school students to develop entrepreneurial thinking while exploring sustainability. Include interactive content, inspiring founder stories, gamified challenges and quizzes on topics such as energy, mobility, air, water, food and agriculture, circular economy and healthcare. Help students learn by doing—and encourage friendly competition with peers along the way.
Challenge partner: CEPS
5. Blackout Resilience: Survive the City Without Power
What happens when the lights go out? Design bold, green solutions that help urban communities stay safe, connected, and sustainable during a city-wide blackout.
Challenge partner: Škoda Auto
5. Sustainable Workplace
We want to challenge you to imagine a more sustainable workplace with us; from the design of the office, the structure of the floorplan, and the materials used to how our offices are run, we believe there is a better, greener way.
You will be welcome to visit our Prague office nearby to see the way it is designed and run, with one of its architects as a mentor; the goal is to figure out bold new ideas on how to build and run a workplace better, so we can apply them not only in our Prague office but also in our offices across Europe.
Challenge partner: Edwards Lifesciences
6. Slash the Food Waste
Challenge partner: Potravinové banky
