81295812-Réalisation d'études de préfaisabilité détaillée pour la production d'hydrogène vert et de ses dérivés en Tunisie

Description

Tunisia, due to its renewable energy potential, proximity to Europe, and qualified technical workforce, benefits from good conditions to become a PtX producer and exporter. The technical potential of renewable energies in Tunisia is sufficient to meet both domestic demand and to produce green hydrogen for export. Against this backdrop, a new project H2Vert.TUN will be implemented by GIZ with the Tunisian ministry in charge of energy on behalf of the BMZ (German Federal Ministry for Economic Cooperation and Development). It is planned that the GIZ project under preparation is based on three (3) strategic components, in alignment with the priorities of the Tunisian government during 3 years of duration, from 02/2022 until 01/2025 1-Development of the national green hydrogen strategy: Output: Qualified decision-making bases for improving strategic and regulatory framework conditions for a green hydrogen / Power-to-X economy in Tunisia are available to political decision-makers. Examples of activities: - Support the process of developing a national strategy for green hydrogen, including the development of action plans and roadmaps for key areas - Support the creation of an inter-departmental H2Vert national commission (political level) and an H2Vert council (including, for example, private sector, civil society and research). - Support a national and regional consultation process, involving all stakeholders in government, private sector and civil society - Advise on specific strategies and priorities for green hydrogen and its derivatives (e.g. ammonia, methanol) and international benchmarking to derive techno-economic recommendations for strategic planning documents - Analyze the existing legal and regulatory framework conditions to create a green hydrogen economy in Tunisia - Provide advice on improving the preconditions for the substantial expansion of Renewable Energies (RE) for green H2 production and cost reduction - Support the integration of the future production and transport of green H2 in the long-term planning of infrastructure expansion (electricity and gas networks). 2-Support for the creation of a green hydrogen economy Output: Companies in Tunisia are provided with a better basis for making decisions about investing in a green hydrogen / Power-to-X economy. Examples of activities: - Analysis of the investment conditions (and barriers) for the planning, risk assessment, implementation, and control of large public-private projects for the production of green hydrogen. - Expert advice to national decision-makers to identify new financing mechanisms, in dialogue with research institutions, companies, industrial associations, engineering associations. - Organizational advice to relevant actors for the creation of a Tunisian observatory as an information hub for global and national hydrogen trends. - Methodical advice for the analysis and optimization of generic business models for green hydrogen economy projects in Tunisia including the development of first concept studies for local value chains. 3- Strengthening research, training, and innovation Output: A technology roadmap for green hydrogen and its Power-to-X derivatives products with an associated action plan has been published in a participatory manner by national and international research institutions Examples of activities: - Promote professional exchange on green hydrogen - Promote active women's participation at training courses. - Organizational advice on strategic partnerships with German partners for a green hydrogen economy. - Develop the communication concepts and related instruments - Technical advice to relevant stakeholders on additional /training courses on critical aspects of the certification of green hydrogen and its Power-to-X derivatives - Process support for national decision-makers in the development of national and / or adaptation of international standards for green hydrogen / Power-to-X Lot 1: The objective of this mission is to carry out four (4) prefeasibility studies to produce green ammonia from green hydrogen. The details of the sites will be provided to the contractor after signature of the contract. The prefeasibility study must take into consideration the technical aspect as well as the financial aspect and include the impact of the project to be carried out on safety, the environment and legislation. The main components of this mission, for each study separately, are deducted as follows: - Technical component - Economic component - Conclusion The components are detailed below. 1- The technical component The contractor will have to carry out the study, engineering, and design of a new ammonia production unit from green hydrogen and renewable energy. This unit must be reliable, efficient, and economically profitable. It must include the engineering in detail, the details concerning the construction of the equipment, their data sheets, the necessary information in relation to the testing of different equipment separately in the factory, the necessary information relating to the transport of the equipment on site, the needs for construction of civil engineering premises for the equipment to be installed and for the staff offices, the necessary details in relation to the installation on site and the needs for the commissioning of all the equipment, skilled labor, basic equipment for maintenance, as well as any other information considered essential to the smooth running of the project. The station must include all the units necessary to have a self-contained and profitable station. The must include the following units: - A renewable energy source - A seawater desalination unit - A source of green nitrogen generation - A green ammonia production unit considering all the connections necessary for the correct operation of the unit. The electricity production and seawater desalination units can, if necessary, be located on different sites from the green ammonia production sites. In this case, the technical solutions, and their costs in relation to the transport of water or electricity to the production site (the new station) must be included in the study. The technical component of each prefeasibility study must include, for each site separately, additional sub-studies and this: - A HAZOP study: It is understandable to carry out a HAZOP study (Hazards and Operability Study) for the identification of hazards and the methodical study of the effects of deviations on each operating process in the unit to be installed. - An environmental impact study: The purpose of this study is to identify and assess the risks of environmental impacts arising from the four projects mentioned above. Its content must be proportionate to the environmental sensitivity of the four predefined areas, to the size of the works to be carried out and their foreseeable impacts on the environment and human health. 2- The economic and financial component Following the completion of the technical study (component 1) which will allow us to obtain the costs of the equipment and its installation on site, the economic and financial component of the pre-prefeasibility study will have to support the decisions in relation to the prefeasibility of the project. This part of the mission must assess the projected costs of the project, identify the financial risks of the project, develop a financing plan, analyze the financial balance of the project, provide a cash flow statement, and assess the profitability of the project. 3- The Conclusion The final part of the prefeasibility study must clearly indicate the choice of the optimal solution as well as a comparative assessment of the advantages and disadvantages according to the criteria selected. The contractor will have to write his recommendations to help decision-making for the realization of the projects.
