Conference full paper

"Then I say the Earth belongs to each generation during its course, fully and in its right no generation can contract debts greater than may be paid during the course of its existence"

Thomas Jefferson, September 6, 1789

"You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete."

Buckminster Fuller, philosopher, futurist and global thinker (1895 - 1983)

"If there are to be problems, may they come during my life-time so that I can resolve them and give my children the chance of a good life."

Kenyan proverb

H2RES user meeting 

The H2RES user meeting is proposed as a recurring meeting of the growing community  of users and developers of the  Open source H2RES energy system model. Originally developed within the INTERENERGY project, H2RES is a long-term energy planning model designed to represent power-to-X and demand response technologies and to explore energy transition pathways toward fully renewable, 100% renewable-based energy systems, with particular focus to the flexibility options required to balance high shares of variable renewable generation. As the community of users grows, there is an increasing need for a dedicated space where users and developers can meet directly. The event seeks to connect them to share practical experiences across different applications, discuss the model’s planned development, and consider how community contributions can be reviewed and incorporated into the officially released versions of the model. In doing so, the meeting aims to strengthen the community around H2RES and to improve coordination between the independent development efforts emerging across institutions.

H2RES now has a new online home, a single entry point to the model, its team and its documentation at https://h2res.org, with every new release published openly on GitHub. This first “H2RES user meeting,” hosted at the 21st SDEWES Conference in Las Palmas de Gran Canaria, opens a new chapter for the model’s community. The hybrid format allows both on-site and remote participants to present their work and take part in the discussion. Looking ahead, the aim is to establish this meeting as a recurring, semiannual H2RES user conference, held online or alongside future SDEWES conferences. Researchers and practitioners working with H2RES, or interested in adopting it, are welcome to join.

Objectives

  • Present the latest developments of H2RES (new model version, graphical user interface, data and input handling, and renewed website) to the user community.
  • Showcase ongoing and completed research projects that apply H2RES, fostering collaboration and the exchange of methods and results among research groups.
  • Hear users' experiences with the model across different case studies and applications.
  • Discuss how user-contributed code can be reviewed and integrated into released versions.
