The Hanseatic Natur GmbH is a regional heat suppliers and energy service provider based in Hamburg-Harburg . The company is a 100% subsidiary of Hansewerk . The main business areas include the supply of heat, cold and steam as well as the supply of electricity from plants with combined heat and power , the technical operation of third-party plants and the conversion of renewable energies into electricity. There are 6 operating sites. These are located in Hamburg , Oldenburg (Holstein) , Fockbek , Ribnitz-Damgarten , Wittenberge and on Sylt . In regional terms, the company essentially covers the federal states of Hamburg, Schleswig-Holstein , Mecklenburg-Western Pomerania and the northern part of Lower Saxony .

history

The company is the successor company of E.ON Hanse Wärme GmbH, which was renamed in October 2014. Until 2006 the company operated under the name of the North German Energy Agency NEA. The predecessor company NEA emerged from the advertising agency for house and industrial gas GmbH, a subsidiary of the Hamburg gas works "HeinGAS", which was founded on July 5, 1927.

Companies

The company operates around 150 local heating networks with a length of over 900 kilometers. Residential complexes, public facilities and commercial operations are supplied with heat via the heating networks, combined heat and power plants and heating centers. In addition to heat from processes with combined heat and power , heat from boilers and waste heat, for example from industrial processes ( waste incineration ), are used. In addition to decentralized heating, the company also uses contracting models to supply steam and cooling as well as electricity from cogeneration. The company is one of the largest operators of decentralized combined heat and power plants in northern Germany. The company operates over 170 combined heat and power plants. These are mostly operated with natural gas, but biogas , bio natural gas , landfill gas or sewage gas are also used. The combined heat and power plants operated cover a power range from 5.5 kWel to 2,000 kWel.

Projects

In the context of the cooperation agreement "Energy Concept for Hamburg" concluded between HanseWerk AG (then E.ON Hanse AG) and the Free and Hanseatic City of Hamburg, which was presented at the state press conference on November 29, 2011, HanseWerk Natur GmbH had extensive tasks. Among other things, the company is committed to expanding combined heat and power, expanding or compressing the heating networks and storage capacities, opening up the heating networks for business partners and increasing the coupling of industrial waste heat.

Multifunctional storage tank Karlshöhe

In 2011, the company put the multifunctional storage system in Hamburg-Bramfeld into operation. By integrating the storage tank into the heating network, not only the solar thermal heat from the solar settlement in Hamburg-Bramfeld can be stored, but also the heat that is generated in the waste incineration plant in the stack field and in the cogeneration units for the network. In addition, the connection to the network offers the possibility of integrating further solar thermal systems into the circuit. However, the technical effort for the integration is only worthwhile from a system size of at least 100 square meters. The technical basis for such a feed is currently being tested in a pilot project. A solar thermal system on one of the company's heating houses in Hamburg-Wandsbek serves as a pilot system . The knowledge gained here should serve as a basis for future offers to solar system operators.

Business partner

Decentralized energy generation is more economical, the more heat generated can be used. Without systemic integration into larger heating networks, considerable heat potential remains unused. The company is therefore opening up its heating networks to business partners with the option of feeding climate-friendly energy into the network, storing it there and withdrawing it again. Several projects have been implemented, for example with Eurogate.

“ Virtual power plant ” for balancing energy

The company bundles 15 of its combined heat and power plants in Hamburg and Mecklenburg-Western Pomerania into a so-called "virtual power plant". This is used for grid stability, as it can compensate for fluctuating amounts of electricity from regenerative generation (wind, sun). Depending on the grid situation, the combined heat and power plants are ramped up or shut down. Together they can supply additional energy or reduce the electricity supply (control energy ). The heating supply of the connected households is ensured by the heating networks and heat storage. Such a project is also in preparation in Schleswig-Holstein.

Highly efficient combined heat and power plants

In Hamburg-Wandsbek and Hamburg-Wilhelmsburg, two combined heat and power plants are operated with an overall efficiency of close to 100 percent. Due to the parallel generation of electricity and heat in one work step, combined heat and power plants already achieve high overall efficiency (electrical + thermal efficiency). By using a large heat pump for heat recovery, the overall efficiency of the systems in Wandsbek and Wilhelmsburg can be increased to around 100 percent.
