The energy transition is a dominant topic in Germany. The government, policymakers, financial actors, and research and development (R&D) organizations are working together to achieve the desired goal of a clean energy transition. The energy transition is therefore a unique opportunity for entrepreneurs, established players, service providers and others to adapt and develop new businesses. Valuable deep-tech and business model innovations are taking place in the energy sector with increasing speed. A data-driven approach to technology assessment is a promising option to better understand and follow recent developments.
