Renewable electricity derived from PV power and wind power are clean and abundant, but is dependent on the weather and seasons, resulting in an imbalance between supply and demand. To solve this problem, studies are being conducted on safely storing and utilizing energy on a large scale by convert-ing renewable electricity into hydrogen energy carriers.This team will develop renewable energy network technolo-gies to healthy and robustly introduce renewable energies that improve the energy self-sufficiency ratio and pose a low envi-ronmental burden. To introduce electric power sources that natu-rally fluctuate with the weather conditions (e.g., solar and wind power generation) into the exist-ing energy network, this team is conducting studies on the smart control of power condition-ers (smart inverters) for stable electricity supply, the utilization of hydrogen energy storage sys-tems and batteries for smoothing fluctuations, and system integration technologies for interop-erability of multiple distributed energy resourc-es (DER).The team is developing technologies to make DER smarter and stabler. It also proposes a new energy supply model that considers electricity users’ convenience by optimizing energy stor-age systems using batteries and hydrogen as well as smart demand response system through the integration of information and communica-tion technologies (ICTs) and meteorological monitoring technologies.ResearchSubjectsHydrogen Energy Carrier TeamUnified demon-stration system of hydrogen energy carrier production / utilizationLaboratory for performance evaluation of PV modulesLaboratory for rperformance evaluation of PVmodules“Storing and Carrying” Renewable Energy as Hydrogen Energy CarrierEnergy Network Team●Smart system technologies for maximum introduction of renewable energy●Establishment of platform for developing smarter DER system　（distributed energy resources）●Comprehensive evaluation technology for solar photovoltaic power systems●System for producing, storing, and utilizing hydrogen with renewable energy●Development of utility-friendly DER and its advanced control technologiesSmarter “Production, Storage and Utilization” of Renewable Energy through IntegrationResearchSubjectsFREA’s concept of renewable energy networkImage of a community that uses renewable energy and hydrogenmon-tem ofnergyuctionMCHTolueneLarge TanksSystem Integration to Facilitate a High Penetration of Renewable Energy1ThemeResearch and verification of advanced integration of distrib-uted energy resources (DER) and related technologies(test bed)●Highly efficient hydrogen energy carrier production technology●Highly efficient hydrogen energy carrier utilization technology●Proposal of a unified system of hydrogen energy 　carrier production and utilizationHydrogen energy carriers are chemical com-pounds containing hydrogen (e.g., methylcyclo-hexane (MCH) and ammonia) and are suitable for long-term and stable storage and easy trans-portation because they are light and compact. This team has been developing highly efficient technologies for hydrogen energy carrier pro-duction using catalytic synthesis and hydrogen energy carrier utilization technologies including for use in co-generation engines and gas turbines as well as hydrogen power generation. In addition, the team is conducting large-scale demonstrations of a unified system for hydrogen production through water electrolysis, hydrogen energy carrier production through catalytic syn-thesis and the use of thermal engines.Open test-bedHydrogenenergycarrierGridGridGridGridGridGridPV powerWind powerPowerelectronicsCo-generationFuel cellsHydrogen generatorFlexible andopen controllerOpen test-bedHydrogenenergycarrierGridGridGridGridGridGridPV powerWind powerPowerelectronicsCo-generationFuel cellsHydrogen generatorFlexible andopen controller3
