The final objective of the GRASSHOPPER project is to create a cost effective, flexible, MW-size FCPP unit based on the learnings from a 100kW pilot plant design, implementing newly developed stacks and MEAs. This pilot plant is large enough to implement cost savings as well as to validate operational flexibility and grid stabilisation capability via fast response. This unit will be installed in Delfzijl, the Netherlands. The project has the following specific objectives:
1. Development of a durable stationary MEA utilising automotive industry CCM construction and processes leading to >65% MEA cost reductions (€/kW).
2. Development of a large area (up to 300 cm²) flow field stack, capable of high power densities (>0.68 W /cm²) as well as dynamic load following operation.
3. Development and validation of a new stack platform with 4x higher power output (6 -> 25 kWe) under FCPP operating conditions (reaching TRL 6).
4. Development of stack production process and >100 kW pilot production of new stacks demonstrating MRL 6 while achieving a stack cost reduction down to 450 €/KW (@ 25 MW/yr production scale).
5. Establishing optimal stack operating conditions to maintain FC efficiency > 55% and lifetime > 20,000 hrs
6. Design, construction and validation of a modular, low cost 100 kW pilot plant.
7. The flexible demand driven operation will be demonstrated with a set point range between 20 to 100 kW and a ramp-up rate delivering 50kW within 20 sec and delivering 100 kW within 60 sec.
8. Adapting the current ASPEN® MW FCPP model to the new design, assisting in efficiency and cost optimisation to reach >50% electrical efficiency and availability expectation > 95%.
9. Design of a flexible and modular MW FCPP with estimated CAPEX below 1500 €/kWe at a yearly production rate of 25 MWe.
10. Dissemination of the development of flexible FCPP through various channels, at least:
a. Two “gold” open-access publications to report to the scientific community the initial performances of a real-world PEM-based system and the long-term performances when coupled with the grid. Other public results could be disseminated through the “green” open-access system.
b. Two public workshops to showcase project results to interested stakeholders and users at various academic, industrial, political and public levels.
c. Business case development for the mainstream application of FCPP as grid support together with an advisory board formed by different stakeholders: AkzoNobel, Tennet (TSO), SWW (DSO).
d. Lateral networking for exchanging experiences with other European smart grid projects using platforms such as:
i. GOFLEX: addition of FCPP as additional typical prosumer for grid support services
ii. ETIP SNET (The European Technology and Innovation Platform Smart Networks for Energy Transition)
iii. Bridge 2020 (Cooperation group for all LCE Smart-Grid and Storage projects funded under Horizon 2020).
GRASSHOPPER’s ambition is fully in line with the 2023 FCH-JU cost targets of 1500 €/kW from the Multi Annual Work Plan 2014-2020 for Industrial: Large scale installations for industrial use (0.3 – 10 MW) as well as Grid support and district use (1 – 30 MW).
