Ukraine is facing major energy challenges and biomass as a resource could substantially contribute to the supply of heat, power and fuels. Since 2014 the Netherlands has been supporting Ukraine in revealing the full potential of reliable and high-quality biobased energy production through "Dutch-Ukrainian Seminar on Bioenergy Cooperation". This year the seminar took place on the 21st of September in Kiev within the 12th “Biomass for Energy” Conference in Ukraine. It was organized jointly by the Dutch consortium "Partners in International Business - Biobased Energy Ukraine" and Scientific engineering center “Biomass” with the support of the Netherlands Embassy in Ukraine and the Bioenergy association of Ukraine. The focus of this year seminar was on use of biomass in district heating of municipalities of Ukraine. Besides the Dutch companies, the seminar attracted Ukrainian representatives of state and local authorities, DH companies, commercial companies, bioenergy and energy efficiency associations, consulting, research and legal institutions.
