Energy hub optimization framework based on open-source software & data - review of frameworks and a concept for districts & industrial parks

Multi-model energy systems are gaining importance in a world where different types of energy, such as electricity, natural gas, hydrogen, and hot water, are used to create more complex but also more economic energy systems to support deep decarbonization.  While the research community is using open source for a long-time collaborative work on open-source tools is not yet the norm within the research community.  To increase the open and sharing efforts between research organizations governments are driving publicly funded projects to share their outcomes.  The proposed open-source framework is based on the principle of maximizing the reuse of existing data, software snippets and packages, and add individual code only as necessary.  A screening of more than hundred software packages identified six suitable open-source frameworks to be partly incorporated into the new open-source framework.  The best parts of each of these frameworks are combined in a way that utilizes limited human resources in an optimal way.  To further improve the so created energy system framework additional features such as a scenery model to incorporate shadowing and elevation effects on conventional and renewable power generation technologies are included.  Going forward, this approach allows to expand research into urban air assessment in which traffic and energy emissions can be assessed jointly

Developing a Community of Practice Around an Open Source Energy Modelling Tool

Energy modelling is critical for addressing challenges such as integrating variable renewable energy and addressing climate impacts. This paper describes the updated code management structure and code updates, the revised community forum and the outreach activities that have built a vibrant community of practice around OSeMOSYS. The code management structure has allowed code improvements to be incorporated into the model, the community forum provides users with a place to ask and answer questions, and the outreach activities connect members of the community. Overall, these three pillars show how a community of practice can be built around an open source tool and provides an example for other developers and users of open source software wanting to build a community of practice

Why Should Saudi Arabia Diversify Its Economy?

International audienceClimate change is a global issue. According to an IPCC special report (IPCC, Global warming of 1.5 °C. An IPCC special report on the impacts of global warming of 1.5 °C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty. World Meteorological Organization, Geneva, Switzerland, 32 p, 2018), if global warming is 1.5 °C above pre-industrial levels, this will increase the threat of climate change, challenge sustainable development and increase poverty in the world. All countries must reduce their greenhouse gas (GHG) emissions. The attention paid to countries that produce fossil fuels and export them to the rest of the world is evident in this context. Like other oil-producing countries, KSA faces two challenges for the 2020s: the consequences of the world’s low carbon energy transition and the changes associated with economic diversification and the growth of the low carbon economy at home. The country should diversify its economy and develop sustainable projects, like smart cities and sustainable tourism, in order to achieve the Agenda 30 aims and the UN Sustainable Development Goals
