100% RE Cities

Proposed Chair of HWG : Gerhard Stryi-Hipp – Fraunhofer-ISE (DE)

Proposed Vice-chair: Prof. Dr. Birol Kilki, Fellow ASHRAE

Members of the HWG:

Name of the HWG: 100% RE Cities

Proposed duration: From 01/2019 to 12/2021, duration: 24 months

Objectives / goals

  • Development of a definition of 100% RE Cities (in line with other initiatives, e.g. for Positive Energy Districts (PED), 100% RE Cities includes energy for heating, cooling, electricity and mobility)
  • Description of technological solutions (energy systems and components)
    to achieve 100% RE Cities
  • Identification of technology gaps to design and implement 100% RE Cities and development of technology strategy and roadmap to fill these gaps with a specific focus on RE heat generation
  • Development of an overview on 100% RE Cities best practice examples
  • Evaluation of planning tools to design 100% RE Cities and development of a proposal, to develop missing tools
  • Evaluation of barriers and advantages to use RE sources for electricity and for non-electricity heat generation (solar thermal, geothermal, biomass)
  • Development of business cases and perspectives to use RE sources for heat generation
  • Development of a guideline to design optimized energy systems for 100% RE Cities under specific consideration of RE sources for non-electricity heat generation

Actions / description of methodology

  • Sub-groups will be established, e.g. on technologies evaluation, planning tools, guidelines (dependent on the number of participants)
  • Physical meetings are planned 2 times a year, discussing the progress
  • Webmeetings will take place in between the physical meetings (every 4-8 weeks)
  • Status of tools, technologies, etc. will be developed by literature recherché
  • Definitions, tools, guidelines will be developed by scientific partners and reviewed by the entire group

Work package structure

  • WP 1 Definitions and overview of initiatives in the field of 100% RE Cities (Smart Cities, PED,…)
  • WP 2 Technological solutions for energy systems for 100% RE Cities: Status and perspectives
  • WP 3 Non-electricity heat generation: Evaluation of technologies, business cases, perspectives
  • WP 4 Evaluation of planning tools and development of guidelines for 100% RE City development

Timeline / Milestones

  • Month 6: Report with definition of 100% RE Cities and overview on related initiatives
  • Month 12: Report on status of planning tools and proposal for tool development (if needed)
  • Month 12: Report on 100% RE Cities best practice examples overview
  • Month 24: Guideline for the development of 100% RE Cities

Deliverables

  • Report of best practice examples
  • Report on planning tools and proposal for tool development
  • Guideline for development of 100% RE Cities including definition of 100% RE Cities
  • Technology development strategy and roadmap for technologies and systems for 100% RE Cities, which are not sufficiently covered yet, with a focus on RE heating and cooling technologies
