Research project HINT

New Zealand-German Platform for Green Hydrogen Integration



Green hydrogen is a key element of energy transition. It is required for the decarbonisation of industrial processes as well as for numerous technical solutions for the efficient integration of the electricity, heating and transport sectors. As there is still a great need for research and Germany will be dependent on hydrogen imports, it is important to establish research and trade partnerships with reliable third countries. Against this background, the German Federal Ministry of Education and Research and the New Zealand Ministry for Business, Employment and Innovation have jointly initiated the Green Hydrogen Research Co-operation with New Zealand. One of three funded projects is the HINT project, which is primarily focussing on the development of methods for investigating the integration of large quantities of green hydrogen into the energy systems of Germany and New Zealand.   

Research project HINT



August 2022 to July 2025

Funded by

  • German Federal Ministry of Education and Research
  • New Zealand Ministry for Business, Employment and Innovation

Project participants

  • University of Canterbury (NZL)
  • Institute of Networked Energy Systems
  • University of Auckland (NZL)

In the project, research teams from both countries will expand and improve the data and methods of model-based energy system analysis on different spatial scales. The focus is on improving the consideration of hydrogen use in cities and neighbourhoods, including industry and the transport sector, as well as the supra-regional transport of hydrogen. To this end, the REMix and FlexiGIS energy system models developed at DLR and published under an open license are being further developed together with the New Zealand project participants. On this basis, the models will then be used to assess various supply concepts for green hydrogen and their interaction with system integration at local level. In this way, HINT provides important orientation knowledge for the implementation of the energy transition. In addition, the project will produce harmonised analyses for the respective target countries, from which principles for system architectures can be derived that can contribute to the timely and cost-effective production and use of large quantities of green hydrogen.

Based on the National Hydrogen Strategy, the Institute of Networked Energy Systems is using the REMix modelling framework in the HINT project to evaluate various supply strategies (e.g. for near-demand production, to offshore hubs or for import) for green hydrogen in terms of their impact on regional energy systems in Germany. In addition, a REMix model for New Zealand is being developed together with the other project participants in order to assess the export potential for hydrogen there. In another focus, the researchers are investigating how electrolysers can be implemented economically and technically at the urban level using geographic information systems (GIS). This is being done using the FlexiGIS modelling tool, which is applied to cities in New Zealand for the first time.

The research project offers an excellent basis for long-term collaboration as part of a broad research and innovation network. Through the joint development of methods and the exchange of researchers, as well as through workshops with stakeholders and the preparation of joint scientific publications, the basis for close and sustainable cooperation for the purpose of promoting innovation and achieving climate targets is realised.
