Hamburg, one of the leading cities in Germany, is renowned for its approach to sustainable development. The city leverages its resources and expertise to introduce modern technologies and ecological solutions that help address the challenges of climate protection and sustainable growth. Through strategic initiatives and investments in innovative projects, Hamburg continually strives to improve the quality of life for its residents and enhance energy efficiency.
One of the central research hubs in Hamburg is the "Energy Campus Hamburg" technology centre at the Hamburg University of Applied Sciences (HAW Hamburg). It focuses on addressing the challenges of the energy transition. Through an interdisciplinary approach and advanced laboratories, the centre develops and tests innovative technologies related to renewable energy and smart energy grids.
Additionally, the "EnergieNetz Hamburg" project, implemented by a citizens' cooperative, engages residents in the city's energy transition. The "PV tenant power" model involves the direct supply of energy from rooftop photovoltaic systems to multiple tenants in a building. This contributes to the decentralisation of the energy system and increases the share of renewable energy in the city's energy mix.
HafenCity, the largest urban revitalisation area in Europe, transforms former port areas into a modern, carbon-neutral waterfront district. This project includes the construction of residential buildings, offices, educational institutions, and cultural and recreational facilities. All of this is done with a focus on building energy efficiency, sustainable mobility, and climate change adaptation.
Hamburg Wasser, the operator of wastewater treatment systems in Hamburg, converts fermentation gas produced during sludge treatment into biomethane. This allows the treatment plant to cover a significant portion of its electricity needs, and the resulting biomethane is used for climate-friendly heating and cooking, significantly reducing CO2 emissions.
At the Technical University of Hamburg (TUHH), an innovative energy storage system has been developed, using high-temperature heat to store and release energy. This system features low costs, high scalability, and minimal environmental impact, making it an efficient solution in the city's energy transition.
Through these initiatives, Hamburg becomes a model for other cities, demonstrating how modern technologies and eco-friendly solutions can be effectively implemented in urban spaces. More information about these practices can be found in the publication: "Energy management in the city. Best practices".
