Changing the Game of Energy - an iconic power plant of the future is being built at the Hamburg-Moorburg power plant site

"Changing the Game of Energy" - this is the motto under which HH2e AG, Uniper SE and Siemens Energy AG intend to develop the production and supply of green hydrogen as well as green process and district heating at the Hamburg-Moorburg site. In this way, the project partners want to jointly enable the decisive step towards an integrated energy transition and bring renewable energies to the sectors that have so far emitted particularly high levels of CO2. To underline the innovative future character of the project, the partners also intend to establish a hydrogen trading platform.

Hamburg, 24.02.2021: In the last 20 years, the expansion of renewable energies has succeeded. Their share in today’s electricity generation mix is around 50 percent. This is a remarkable success. However, the heat and mobility turnarounds are still in their infancy. In the “second half” of the energy transition from 2020 to 2050, it is therefore time to bring together the electricity transition, the heat transition and the mobility transition into an integrated, genuine energy transition.

HH2e AG stands for a system of renewable electricity, hydrogen and energy storage. Together with Uniper SE and Siemens Energy AG, the next stage of the energy transition is to be initiated at the Hamburg-Moorburg power plant site in an iconographic power plant of the future that will supply industry and the people of Hamburg with green energy around the clock.

Alexander Voigt, CEO of HH2e AG:

“With this project plan, we are formulating a concrete offer to Hamburg and all stakeholders who would like to participate in the project in the future. Our vision and our goal is that in the future, Hamburg will be seen as a motivating example throughout Germany and Europe when it comes to making the real integrated energy transition a success in terms of security of supply, affordability for all and, above all, through new, innovative partnerships.”

A high-temperature storage system, an electrolyser and an innovative gas turbine are three main components of the iconographic power plant of the future:

These innovative technologies make it possible to store large amounts of wind power as high-temperature heat and provide it on demand. Renewable energies are integrated into the heat sector in this way on a large industrial scale. Part of the stored energy is supplied to Hamburg’s industry as process steam. Another part can be converted into oxygen and hydrogen by a new innovative electrolysis technology.

This makes it possible to supply large quantities of green hydrogen directly to industry and other customers, e.g. in the mobility sector. In the long term, this will make it possible to meet the hydrogen needs of Hamburg’s energy-intensive industry completely without emissions.

On the other hand, green hydrogen will be converted into climate-friendly electricity and green district heating with the help of a low-NOx, highly efficient gas turbine, thus enabling a climate-neutral public energy supply for commercial enterprises, households and public institutions in Hamburg.

Andreas Schierenbeck, CEO Uniper SE: 

“With our corporate strategy “Empower Energy Evolution”, Uniper has set itself a clear target for consistent CO2 reduction. In the European generation segment, we want to achieve net zero emissions by 2035. To achieve this, Uniper is investing in projects that accelerate the transition to a CO2-neutral world. We are pleased to be a partner in the project development in Moorburg, because this project fits very well into our green portfolio and our corporate strategy. Therefore, from the very beginning there was no question that we would bring our experience and at the same time a great commitment to this project.”

Dr Jochen Eickholt, Member of the Managing Board, Siemens Energy AG:

“The new power plant of the future in Hamburg will be a prime example of decarbonisation: an electrolyser for the production of hydrogen, a hydrogen-capable gas turbine and an innovative high-temperature storage facility – all the ingredients of a successful energy transition are combined here. As Siemens Energy, we are proud and pleased to be making an important contribution as a technology partner to the success of the project and thus to the transformation of the energy markets.”

A hydrogen trading platform in Hamburg sets standards for future H2 trading:

The development of an integrated energy system is to be accompanied by the creation of a hydrogen trading platform, which will become an international marketplace for the physical and balance-sheet trading of hydrogen, but also of other power-to-X energy carriers derived from green hydrogen, such as ammonia, methanol or synthetic fuels. This platform is to become an important contribution to the development of a regionally, nationally and globally networked hydrogen economy, of which Hamburg will be an important power centre.

Together with other project partners, HH2e AG has submitted a detailed project outline to the Expression of Interest in the so-called EU Projects of Common European Interest (IPCEI) on 19 February 2021. The Hamburg Senate expressly supports the efforts of the companies to make Hamburg a hydrogen location.

However, the iconographic future power plant should not remain a purely business enterprise initiative. Rather, the energy turnaround requires the direct participation of as many Hamburg residents as possible and numerous social actors in the Free and Hanseatic City. The initiators of the project therefore want to enter into an intensive dialogue with the citizens and numerous stakeholders in Hamburg as soon as possible.
