Digest of Grand Renewable Energy 2018 International Conference●Conference Name: Grand Renewable Energy 2018 International Conference(Grand RE2018 International Conference)
Associating The 13th Renewable Energy International Exhibition●Date and Venue: June 17 to 22, 2018 in Pacifico Yokohama, Yokohama City, Japan
Summary
The conference was successfully terminated, which was held for June 17 to 22, and the technical tour
on June 23, The Exhibition for June 20 to 22 held all in Pacifico Yokohama, Yokohama city. The
remained work hereafter is to prepare DVD fabrication in which full papers collected in the conference
onsite are compiled, and the uploading work to J-Stage to be commenced after the DVD completion.
The preparation of the conference was started after the kickoff meeting held on January 23, 2017,
where all key persons were gathered, METI Director, Mr. Takuya Yamazaki had a speech forencouragement. 250 members from domestic and 150members from oversea countries were gatheredfor preparatory work.
In the conference, 1,121persons from 47countries participated with 713 paper presentation, 5keynote
Speeches by the representative from Japan, IEA, China, USA, and Germany. The 15 renown speakers
were invited from all over the world. In addition, one work session titled RE100, six special sessionsorganized by Japanese socio-governments, IEA, Germany Agency, and The University of Tokyo. Morethan 1,000 persons attended to these sessions. In Exhibition, about 22,000 visitors except for theconference participants came to the various countries.
Conference Aim
The solid slogan is “Advanced Technology Paths to Global Sustainability”, which means thetechnology development and deployment are indispensable to achieve the global sustainability.
Therefore, we have the open venue to serve the presentation and discuss on the advanced researchand development. We pay attention also to the student to participate as many as possible. To show up,in every final day of the conference, we declare Conference Communique and confirme it among all
the participants.
Conference Structure and Areas
This conference was initiated from 2006, and we decided the international conference is held every

In Grand RE2018, the number of participants and oversea participants decreased compared withGRE2014 and GRE2010. Firstly, one of this reason is the drop from the participants from Republic ofChina, Taiwan, and Korea. Japan must do the endeavor to promote renewable energy technology tobe able to appeal. Second reason was the conference timing to move one month ahead so far, that is,mid.
June because of available venue of international conference due to the preparation of Tokyo Olympic
2020, resulting five sessions out of twelve to be overwrapped with big international conferences held inother countries just in the same week or before and after the week. Third reason was there wasnothing of joint international conference together with GRE2018, while the 2nd Asia AWTEC was heldin GRE2014, where more than 100 ocean energy specialists attended mainly coming from Europe.
However, we must do the next challenge, and want to treat above the reasons just only with excuse.

likeGRE2014 and the big ocean conference held in Spain for the same week.
・Photovoltaics and Biomass encountered worldwide big conference just before the week, but theirendeavors have contributed to minimize the drop of participants. Hydrogen and Fuel Cell was coupled justsame week as big international conference, however, due to the effort of leaders and other members
participants can be kept.
・Reflecting on the renewable energy epoch trend, policy and integrated concept, energy network wereincreased then the former. Leadership by program leaders is also greatly contributed too. Geothermal
Energy and Ground-source Heat Pump was also same.

・It was confirmed that this Grand Renewable Energy Conference is firmly supported by two big pillars ofWind Energy and Photovoltaics.

Final Communiqué fromGrand Renewable Energy 2018
“How to Accelerate Renewable Energy Integration”
PACIFICO YOKOHAMA, YOKOHAMA, JAPAN, 17 – 22 JUNE 2018
Under the theme How to Accelerate Renewable Energy Integration, the 4th edition of the Grand Renewable
Energy International Conference was held this week in Yokohama, Japan. The Conference was attended byover 1100 participants, representing 45 countries. Besides Keynote Addresses and Panel Discussions,experts from international organizations and institutions, industry and governments delivered presentations
and posters in a broad cross-section of renewable energy issues related to technical, scientific, economic,
social and environmental aspects of renewable energy integration in society.
Based on the various presentations and discussions at the Conference, the following fundamental
understandings and proposals have been reached to provide directions on how to accelerate renewable energy
integration around the world:●Since the beginning of this conference series in 2006, held every four years in Japan, contributions ofrenewable energy continue to increase, and the public further recognizes its importance.
●We have observed a continuous growth in renewable energy deployment worldwide, with renewableenergy-based power generation now being the dominant new power source installed in the world. In
2017, 70% of total new power generation installed was based on renewable energy sources.
●While continuing to be the object subject of innovative research and development, wind and solar
photovoltaic (PV) systems solar PV have achieved technological maturity and are now cost-competitive
with traditional power sources. Is, and, in some areas in the world, wind and solar PV have become thelowest power sources.
●While penetration of variable renewable energy integration has already exceeded 30% of electricity
generation in certain jurisdictions, power systems need to evolve towards more renewable energyfriendly systems to increase flexibility in grid management.
●Importance of energy storage has become more widely recognized. Not only pumped hydro storage but
also large-scale battery systems are being installed to control the output from variable power sources.
Hydrogen and hydrocarbons produced from renewable energy are expected to become significant energy
carriers in the future.
●The world continues to meet more of its energy demands through electrification. In this regard, on the
short term, the transportation and heating & cooling are sectors where renewable energy can be deployedmore widely.
●Continued cost reductions, system friendly policies and well-designed economic rules are crucially
important and effective for further deployment of renewable energy for future energy security andsustainability.
The scientific community, industry and governments recognize that we have achieved significant
accomplishments in the renewable energy sector. However, based on the above, a lot more needs to bedone.
We, the specialists involved in the field of renewable energy technologies and their policies, are committed
to continue to contribute in the development of a viable, efficient, safe and secure energy sector throughout
the world. The next Grand Renewable Energy 2022 International Conference, to be held in Japan, will
provide an opportunity to assess the work and to share the accomplishments that will be done in the next fouryears.
