					Hamburg creates competence bundle
                  Hamburg becomes hycity
                  “Hamburg is the gateway to tomorrow’s energy world – Hamburg is hycity.” For this vision Hamburg
                  has taken the initiative and bundled the competence available in the city. Individuals, companies
                  and institutions who want to get things moving in the field of fuel cell and hydrogen technology are
                  now joining forces. For sustainable energy supplies. For effective climate protection. For a city
                  with top technology.

          An alliance of 10 project partners with Hamburg as lead manager received financial assis-
             tance from the EU for the development of a totally fuel cell powered vessel designed to
               carry 100 passengers. The first fuel cell passenger vessel of this size will be supplied by
                  a hydrogen refuelling station also developed as part of the project.

                     In summer 2008 the vessel will start passenger-carrying operations on Hamburg’s
                     Alster Lake and in the historic Speicherstadt warehouse district: safe, reliable and
                     highly efficient, with low noise and vibration levels, without fuels dangerous to water
                    and without the usual air pollutants. Among other things, the project will also create
                   and secure jobs with a future.

  Airbus is a leading aircraft manufacturer with the position as technology driver and a distinct cus-

           leading position in this sector. Airbus is constantly working on further and new develop-

               board of aircraft provide a good opportunity to connect both aspects in an optimal form.
                Based on existing and upcoming research results it is necessary to find trend-setting
                 measures for the industrial implementation and application of this technology.

Advances in fuel cell technology are fuelling hopes of a new option in energy conversion. Which is
    why E.ON Energie is playing an active part in a number of projects for testing fuel cells. One pre-
       condition for their widespread use is that they must become technically reliable and eco-
          nomically competitive. In future we can expect to see an increasing proportion of small,
           distributed generating units. To be able to assess the technical opportunities afforded
             by these technologies, E.ON Energie is running a number of demonstration projects.

  Hamburg Airport is the fourth-largest airport in Germany   1,600 of them in the Hamburg Airport group. The airport –   Short Profile
  and one of the fastest-growing and most up-to-date in      together with Airbus and Lufthansa Technik – forms the
  Europe. About 13,000 people work at the airport – some     heart of the world’s third-largest aviation centre.

  Environmental protection safeguards the location                                                                         Motivation

  Hamburg Airport has a long tradition in the field of environmental protection. To reduce atmosphe-
     ric pollutants, Hamburg Airport is already using natural gas and LPG as modern, environmen-
         tally sound and low-emission fuels. In future we intend to make further substantial reductions
            in pollution levels. To this end we plan to test the use of hydrogen for low-emission traf-
              fic. Testing and use of innovative technologies will help to safeguard the necessary
                economic framework conditions for operators and our customers.

  As long ago as 1999 the company gained its first experience with the fuel cell powered NEBUS
       (New Electric Bus). From 2003 to 2005 HOCHBAHN operated three fuel cell buses on a regu-
          lar scheduled basis as part of the CUTE project (Clean Urban Transport for Europe) promo-
             ted by the European Union. As a result of the successful testing of this hydrogen tech-
               nology, the CUTE project was expanded and extended until early 2007 under the new
                project name of HyFLEET:CUTE. HOCHBAHN has nine hydrogen buses on the road.
                They will carry on operating even after the end of the project, because HOCHBAHN
                 is to continue the joint tests with Vattenfall, BP and the manufacturer Evobus until
                mid 2008.

                     Despite its local implementation, the motivation of hySOLUTIONS has an international background:
                         Hamburg - like other major cities - is well aware of its responsibility to integrate sustainability

  Since 1910 Linde, as the world’s biggest constructor of hydrogen systems and a leading industrial
       gas company in Europe, has been supplying hydrogen for a wide variety of applications, e.g. in
          the chemical, petrochemical or food industries. With the development of new hydrogen
            technologies – including innovative tank and supply systems – Linde is also a strong
              partner for promoting the use of hydrogen as an energy source for the future.
               We are fully committed to the development of a new reproductive energy source.
                For several years now, STILL GmbH has been working on H2 technology. On the basis
                of experience gained with the operation of a fuel cell powered fork-lift truck at Munich

           We believe in the fuel cell. We are the only supplier to possess the exclusive licence for using
             the exhaust air from fuel cell cathodes to reduce oxygen levels in air. With our ideas and

  Every year, the federal government’s Forest Damage Report provides fresh confirmation: our forests
       are far from healthy. One of the main reasons for damage to forests is exhaust gases from
          road traffic. Systematic further development of clean hydrogen technology and its early
             market launch in road vehicles will make a decisive contribution to the recovery of
               German forests. That is why SDW as a forest conservation association supports the
                 development of the fuel cell.

                                 Vattenfall is Europe’s fifth-largest energy supplier. In Hamburg   with the city. As a modern energy supplier, Vattenfall is       Short Profile

                                 Vattenfall combines its activities in the field of fuel cell and hydrogen technology with new econo-
                                      mic concepts such as rights trading systems or promotion mechanisms, and integrates them
                                         in existing supply structures. We pay attention to environmental impact, cost-effectiveness
                                             and supply security – indispensable criteria for sustainable energy supplies. In view of
                                              their high efficiency and low emission levels, fuel cells are suitable for distributed
                                               energy supplies. Hydrogen is an emission-free energy source that can be produced
                                                by means of offshore wind energy or CO2-free coal-fired power stations. Like electri-
                                                city, it is a secondary energy source that can open up the transport sector as an
