The LIINES is happy to announce that The IEEE Systems Journal has accepted our recent paper entitled: “A Reference Architecture for the Energy-Water Nexus” for publication. The paper is authored by William N. Lubega and Prof. Amro M. Farid. The topic of the energy-water nexus is a timely one. Global climate change, water scarcity, energy security and rapid population are at the forefront of sustainability concerns. Furthermore, the fact that energy and water value chains very much depend on each other complicates how either system should be planned an operated. And yet, the number, type and degree of interactions are hard to identify. While the graphical depiction below illustrates many of the couplings, we are still a long way off from planning and operating this “systems-of-systems” sustainably. And so we ask a first basic question: “How can we begin to quantitatively understand the energy and water interactions in this nexus?” As the paper explains, a good first step is develop what systems engineers call a reference architecture. Plainly speaking, this requires three steps:
- Figure out all the component parts of the energy-water nexus (e.g. power plants, water treatment plants, etc)
- Figure out how each one works
- Figure out the inputs and outputs for each one focusing especially on flows of energy and water.
This starts out qualitatively with flow diagrams like the one shown below: In a sense, this helps us to see the “wood from the trees”. The web of energy and water interactions now become clear for further quantified analysis. As the readers will see in the coming weeks, this is exactly what we have done at the LIINES.
