Growth of the renewable energy sector and a high ecological standard helped make Hamburg the ‘European Green Capital 2011’.

Sustainable Port Industries

The second largest port in Europe, Hamburg's harbour is likely the first thing many people associate with the city. With that sheer economic power, the harbour also has the power to shape the city's sustainability practices. Hamburg's harbour has come to reply on sustainability and is on its way to become an ecologically aware business with the most up-to-date technological standards. For example, the HHLA container terminal is powered by industrial waste heat from the nearby sewage disposal facility, saving up to 1,000 tons of carbon dioxide. It is the HHLA’s declared aim to reduce carbon dioxide emissions 30% by 2020. For the Altenwerder container terminal, a battery management system is being developed to harness wind and solar power. The construction of a wood-chip heating plant, designed to heat the office buildings of the container terminal, has already been completed.

'Going green' for Growth

Ecology and economy go hand in hand in Hamburg. Energy suppliers have pledged to invest in the storage and transformation of renewable energy in order to make Hamburg a global centre for green energy. Today, Hamburg is already regarded as the capital of wind energy, making it quite fitting that Hamburg has been the host of the international Hamburg WindEnergy trade fair since 2014.

In this city by the Elbe river, the advantages of green technologies and their potential for both inhabitants and businesses were discovered many years ago. Now, more than 33,400  employees work in energy generation, green building, water and waste management or energy services. The annual turnover in 2012 was an estimated EUR 10.66 billion and is growing steadily.

A Silicon Valley of Renewable Energies

At the Energy Campus of Hamburg University of Applied Sciences (HAW), scientists and students deal with questions of wind energy, storage technologies and intelligent mains. This so-called 'Silicon Valley of renewable energies' is also a hub for businesses that research environmental topics.

In addition to the research of theoretical approaches to sustainability, many projects have already been realised during the course of the International Architecture Exhibition of 2015. Hamburg's Wilhelmsburg district hosted the exhibition, where a 42-metre-tall anti-aircraft bunker was turned into an energy centre. It now creates energy and heat by means of a biomass power plant, a solar thermal system and a water reservoir. After finishing reconstructions in 2015, the bunker can supply heat for up to 3,000 homes and energy for approximately 1,000 households. 

Wilhelmsburg is also home to several other innovative pilot projects. For example, the Algenhaus ('Algae Fuel House') has large bio-reactionary water reservoirs along its facades, in which algae supply the building with energy by means of producing biomass. And a former waste dump has been transformed into another energy centre delivering wind and solar energy to about 4,000 homes.
