This flagship project is expected to pave the way for further large-scale integration of electrolyser systems in industrial applications in the framework of fully commercial operations. The project should demonstrate in an operational industrial environment improved electrolysis technology at a scale of >25MW, configured to provide the necessary reliability of supply at the lowest possible cost of bulk renewable hydrogen to one or more hydrogen users. It will prove the integration of multi-MW state of the art electrolysers into industrial applications, showing decreased costs for both CAPEX and OPEX, increased operational reliability, improved integration both within the industrial process plant and with an associated renewable energy power plant/power purchase agreement (PPA) (as per regulatory requirements) to ensure high reliability. SRIA KPIs for 2024 for the relevant technology should be met.
Moreover, the project shall prove important additional technological advancement compared to the Djewels project, as well as the three projects that have been selected in the context of the Green Deal call on the 100 MW electrolysers under Horizon 2020.
Project results are expected to contribute but are not limited to the following expected outcomes:
- Emphasise innovation aspects that demonstrate how electrolyser technology goes beyond the current state of the art, while ensuring replicability and wide commercial impact following the implementation of the project;
- Demonstrate reliable operation of large-scale electrolysis and the use of the produced hydrogen in an application valorising the renewable character of the produced hydrogen according to final user’s requirements;
- Gain operational experience, including safety and regulatory framework, of the contractual and hardware arrangements required to distribute and supply hydrogen to the specific industrial environment;
- Perform techno-economic analysis of the performance of these systems showcasing the business case of the proposed solution;
- Technically assess the operation of the electrolyser in the industrial environment regarding contractual and hardware arrangements and suggest best practices;
- Evaluate the life cycle environmental performance of the system (including water usage) in alignment with the applicable regulation, defining renewable hydrogen with attention to the CO2 intensity of the hydrogen produced, which should include an understanding of the CO2 footprint impact in the addressed hydrogen end-user markets;
- Identify the value and size of the markets addressed and the possibility of indirectly affecting additional relevant markets;
- Assess the legislative and RCS implications of these systems and any issues identified in obtaining consents to operate the system;
- Make recommendations for policy makers and regulators on measures helping to maximise the value of renewable energy and stimulate the market for renewables-electrolyser systems.
Project results are expected to contribute to all of the following objectives of the JU as reflected in the SRIA:
- AEL, Electricity consumption @ nominal capacity (kWh/kg) 49, Capital cost €/(kg/d) 1,000, O&M cost €/(kg/d)/y 43, Degradation (%/1,000h) 0.11, Current density (A/cm2) 0.7, Use of critical raw materials as catalysts (mg/W) 0.3;
- PEMEL, Electricity consumption @ nominal capacity (kWh/kg) 52, Capital cost €/(kg/d) 1,550, O&M cost €/(kg/d)/y 30, Degradation (%/1,000h) 0.15, Current density (A/cm2) 2.4, Use of critical raw materials as catalysts (mg/W) 1.25.
The project should aim at demonstrating electrolyser technologies beyond actual state-of-the-art producing hydrogen reliably under favourable economic conditions and rationale use of water in a specific industrial application to be chosen by the proposers.
The scope of the project is to demonstrate the integration of a large-scale electrolyser of minimum 25 MW. Technical requirements in terms of purity and pressure shall be designed to fulfil the industrial requirements. At least 2 years of operation are expected. Hydrogen production should be >1,500 tonne/yr and the facility should be working more than 3,200 equivalent hours/yr at full load.
Proposal should address innovation aspects that ensure the project goes beyond the state of the art. Examples of innovations could include, but are not limited to:
- Possibly supply hydrogen to two separate users, each with their own operational requirements and managing electrolyser output both in terms of generation and storage in order to maximise the efficiency of the setup;
- Use oxygen and/or waste heat from the electrolyser for other processes at the industrial site, or from the industrial process to the electrolyser in case of SOEL;
- Concepts related to the circular economy (e.g.: water utilisation, re-use of CO2 at the site);
- Provision of grid services that help the economics of the installation;
- Footprint reduction, for example integrating hardware vertically instead of horizontally, or minimising the footprint of the electrolyser with a single balance of plant including all required utilities such as water purification, power rectification with appropriate grid interfaces and hydrogen purification, process cooling, etc.
Given that the topic leaves the possibility open for addressing a broad scope of industrial applications, it will be up to the proposal to clearly specify these innovation aspects and avoid any duplication of previous industrial electrolyser applications. In this regard, proper reference and complementarity to previously funded projects by the FCH JU (e.g. Refhyne, H2Future, Djewels, Multiplhy, MegaSyn) and the Green Deal 100MW electrolyser projects should be included, if applicable.
