Köhlbrandhöft – a self-sustainable wastewater treatment plant

The wastewater treatment plant of Hamburg Wasser has been home to a new wind turbine since the end of July 2014. With an output of 3 megawatts per hour at full capacity, the approximately 200-metre-high turbine generates as much energy as a family of four consumes on average every year.

The wastewater treatment plant in the port of Hamburg – once one of the largest consumers of electricity in the city – has been energy-neutral since 2011. This means that, taken as an annual average, it generates at least as much heat and electricity as it consumes.

The sludge collected during the treatment process provides another rich source of energy. During its decomposition, around 95,000&60;m³ of biogas is produced every day, which is used directly at the treatment plant or processed into biomethane and then fed into the natural gas grid.

Georgswerder Energy Hill – from toxic waste dump to pinnacle of renewable energy

The Energy Hill Georgswerder rises 40 metres above sea level, giving a breathtaking view from the southside of Hamburg to the city centre. It was transformed into a renewable energy hill as part of the International Building Exhibit IBA Hamburg and visitor activities were taken over by Stadtreinigung Hamburg in February 2014. The potential of energy production was fully realized with installation of a photovoltaic system, a new "repowered" wind turbine, use of landfill gas, and installation of a heat pump to recover heat from the cleaned groundwater, providing twenty percent of private households on the Island Wilhemsburg with electricity. It is accessible to the public as a viewpoint.

Wilhelmsburg Energy Bunker

The former flak bunker in Wilhelmsburg has become a symbol of Wilhelmsburg’s renewable climate protection concept. Virtually unused since the end of the war, the monument was renovated as part of the IBA Hamburg 2013 and converted into a renewable energy plant with a large heat reservoir. Get a peek behind the scenes and take part in a free guided tour by Hamburg Energie! The core of the project is a large heat reservoir that was constructed inside the former flak bunker. In the future, it will serve as an energy bunker supplying power to an urban area of more than 1.2 square kilometres (120 hectares) thanks to the integration of different eco-friendly heat and electricity generation plants.

Bergedorf Energy Campus – the silicon valley of renewable energy

The Technology Centre Energy Campus by the Competence Centre for Renewable Energy and Energy Efficiency (CC4E) at the Hamburg University of Applied Sciences (HAW Hamburg) is open for research purposes and features a wind, smart and grid laboratory as well as a wind farm.

By establishing a network of companies, universities and institutions, the energy campus aims to support the development of applied solutions and innovations in renewable energies that will greatly benefit the general public.

Energy plant in Oberhafenquartier

The Oberhafen energy plant of enercity Contracting Nord GmbH provides heat to east HafenCity with its district heating network. In addition to two boilers, a biomethane CHP plant with an output of 1.5 MW is in operation together with a 300 m3 buffer storage system. The CHP is flexible and used to produce electricity, supplying electric energy to the public grid when it is needed. Two enercity charging stations have been available for electric vehicles at the energy plant since 2018. &60;The integration of industrial waste heat from Aurubis AG means that the next development step in supplying heat for the east of HafenCity has been completed for the current heating period.

Super computer at the German Climate Computing Centre

How do climate simulations work and how to they differ from weather forecasts? Climate researchers develop models which simulate the most important processes of our atmosphere, oceans and land surfaces. The calculations performed with these models require cutting-edge supercomputers and vast amounts of memory – such as the high-performance computer “Mistral” at the German Climate Computing Centre (DKRZ), one of the fastest computers in Germany. The supercomputer is essential for the Climate Cluster of Excellence CliCCS.

Trimet wind energy plant

The turbines are one of the largest wind farms in Hamburg, standing a total of 199 metres tall from the ground up to the blade tip. The diameter of the rotor alone is bigger than the height of the Elbe Philharmonic Hall and the surface of the rotor is as large as a football pitch. These giants allow the three new turbines to generate a total of 28 million kilowatt hours of energy every year – equal to the electricity demands of around 10,000 households in Hamburg. With the commissioning of the three turbines, Hamburg Energie is now the largest producer of wind energy in the Hanseatic city. What makes the three new turbines special? They are located in the middle of the harbour's industrial area.

ArcelorMittal’s green steel project H2 for Hamburg (H2H) aims at the first industrial scale production and use of Direct Reduced Iron (DRI) made with 100 per cent hydrogen with an annual production of 100,000 tonnes of steel. The company aims to make a substantial contribution to reducing CO2 emissions in the supply chain. ArcelorMittal’s Hamburg plant will be converted to climate-neutral steel production in four steps by 2030 as part of the H2H project. These include the construction of a hydrogen-powered demonstration plant for the direct reduction of iron ore (H2First) and the technological upgrading of the existing direct reduction plant (H2Ready) to replace the long-term use of natural gas with green hydrogen.
