Tyczka Hydrogen GmbH intends to build and operate electrolysers for the production of green hydrogen, which shall be used predominantly in the transport sector and/or within the framework of THG quota trading. The economic viability of these projects depends to a large extent on the design of the regulatory requirements. With the Renewable Energy Directive of 11 December 2018 (RED II) and the upcoming RED III Directive, the EU has established requirements for the production of green hydrogen. Against this background, it is important to analyse how green electricity procurement via PPAs in particular should be structured in order to meet the quality requirements.
The E-Bridge approach is based on two main steps. First, different PPA contract structures and models were described and a market overview of the PPA contracts concluded so far with reference to H2 production was created. Then options for different portfolio design of PPAs were investigated. For this purpose, the criteria for the production of THG-capable hydrogen (RED II) were analysed and project-specific catalogue of requirements for the purchase of green electricity (PPA) for green hydrogen production was developed. The risks and special features of concluding PPAs were also assessed.
From the presentation of various PPA structures and models the options for compliance with the RED II criteria for the production of green hydrogen can be derived. A high-level draft of a project-specific catalogue of requirements for the purchase of electricity (PPA) for green hydrogen production enables the client to obtain an overview of its options for action for the production of THG-compatible hydrogen in accordance with RED II. Opportunities and risks of concluding a PPAs were assessed.
