Hydrogen for the urban environment
TU Delft - Lancering 24/7 Energy Lab (Green Village)
TU Delft - How does the 24/7 Energy Lab work?
Theme leads: prof. dr. Miro Zeman and prof. dr. John Schmitz
Main challenges:
The overall goal is to design and demonstrate a local energy system with green hydrogen both as energy storage and as fuel for different applications. Specific challenges are:
- Design rules for a local hybrid energy system based on renewable energy sources.
- Contribution of green hydrogen to flexibility in energy supply in a local hybrid energy system.
- Storage and use of hydrogen in built environment.
- Safety, regulatory and institutional issues related to production and use of hydrogen in local neighborhood.
Ambitions / contributions:
Utilization of renewable energy sources (RES) such as wind and solar energy in built environment can significantly contribute to the reduction of CO2 emission. Large-scale deployment of PV systems in neighborhoods creates opportunities to locally produce electricity and consequently green hydrogen. This enables building local hybrid energy systems that can supply sustainable energy to local consumers. Hydrogen, in addition to batteries, can play an important role in increasing the flexibility of energy supply in periods when the primary RES are not available, i.e., when the sun does not shine and there is no wind.
The ambition is to investigate the role of green hydrogen in a local hybrid energy system. Design rules for sizing individual components of an energy system based on RES, such as number of PV modules, power capacity of inverter, electrolyzer, battery and hydrogen storage, will be developed. Design rules will be validated using a real energy system built in The Green Village at the TU Delft campus. Since The Green Village is a living laboratory also the use of hydrogen as fuel for producing heat in buildings will be studied. For this purpose, a multi-commodity grids that have been built by the network operators Alliander, Enexis Groep and Stedin will be use. This research will contribute to realizing a sustainable TU Delft Campus.
