EU-Japan biomass seminar - Sustainable value chains for distributed bioenergy projects

In recent years, the use of wood and wood residues for heat and power production from small-scale decentralized plants has increased in Japan, thanks the adoption of a supportive National policy framework and to the availability of feed in tariffs for electricity. One of the technologies adopted is biomass gasification. Around 20 small-scale gasification plants are currently installed in Japan and more than 90 projects are in the planning phase, most of these installations are based on European technologies. Solutions are needed for adaptating those technologies to the specific site conditions and for the efficient utilization of the forest biomass available locally, in order to ensure a long-term sustainable development of this market sector.

Building on the outcomes of the 1st EU-Japan Small-Scale Biomass Gasification Seminar held in Hiroshima in January 2019, this event will gather experts from research and industry from both Europe and Japan, to discuss the challenges and the solutions for the implementation of efficient biomass value chains for decentralized bioenergy projects in Japan.

The agenda will include presentations on the following topics:

  • Mobilization and storage of woody biomass resources: state of the art in Europe and Japan and applicability to the local conditions.
  • Feedstock quality: biomass pre-treatment, characteristics and compliance with process requirements to maximize the plant’s availability in local conditions.
  • Efficient use of residual heat: combined heat and power, biomass drying, district heating and locally applicable solutions.
  • Processes, challenges and strategies for the valorisation of the solid and liquid by-products of small-scale biomass gasifiers (char and wood vinegar).

A final roundtable with panellists from both Europe and Japan will discuss the opportunities for international research, knowledge transfer and industrial cooperation for sustainable decentralized bioenergy projects in Japan.

The detailed agenda will be available soon.
