Energy supply and demand control is one of the most urgent and critical issues in the current global energy agenda today. Shifting to renewable energy sources is claimed to have high priority, yet numbers of technical, economical, and social issues remain. For industrial countries, the issue is how to transfer the current energy mix into more sustainable sources while maintaining the quality and cost of current service. With regard to developing countries, a “leap frog strategy” that promotes the use of renewable energy along with their economic development could reduce the dependence on fossil fuels.

However, there are many challenges including;

  • Overcoming the unstable and low density per area characteristics of renewable energy sources
  • Matching the energy storage and distribution systems to the renewable energy souce in an optimal manner
  • Integrating the energy demands control and supply scheduling
  • Identifying and solving the economical bottlenecks
  • What are possible identifying and establishing policies, funding models and business strategies that enable practical and sustainable introduction of such systems

The Open Energy Systems (OES) concept is formulated to signify a novel electricity supply and demand control system that assumes open-ended, heterogeneous, fluctuating, and unreliable energy sources. It is a distributed DC grid architecture that can scale from an isolated node to large-scale interconnected systems that may ultimately be connected with the main power grid. OES are expected to embrace the heterogeneous and dynamical nature of renewable energy to mitigate some of the issues. Currently, OIST and Sony CSL are engaged in a joint project on the OIST campus to develop distributed DC-based micro-grid system aimed at fully utilizing renewable energy sources such as solar phot-voltaics, wind turbine, etc. The produced energy is stored on a Li-Ion based energy server units installed in each node of the micro grid system. Sony CSL, with the support of Japan International Cooperation Agency (JICA), is deploying such systems in the northern part of Ghana to electrify some villages.

The symposium is framed around "Open Energy Systems" and its applications to various social and geographical situations such as industrialized cities, isolated islands and remote areas with unstable electricity.

The symposium wishes to bring together technical experts, government officials and business leaders that are potentially interested to co-develop and deploy such systems.   

While electrical energy is the core topic, we wish also to take a broader perspective and address various vital needs and integrative systems including water supply, medical care, education, etc. Consideration must also be given to how societies in various locations can introduce such ideas.

The symposium will also introduce research and development projects on renewable energy production and distribution currently on going in Okinawa, at OIST and at other institutions.

The symposium will take place at Okinawa Institute of Science and Technology Graduate University (OIST: ).
