Recent developments

Current activities

HELE’s current activities focus on:

  • Organising technical tours and workshops. The latest HELE meeting took place in September 2018 in Tokyo, Japan, for which a report is currently under development;
  • Developing a common measurement basis for GHG emissions reductions in participating countries through improvements in operations and maintenance;
  • Encouraging further collaboration to address technical and financial barriers to the greater uptake of HELE plants and identify solutions; and
  • Expanding communication and outreach efforts.


Since its creation in 2009, HELE has:

  • Organised a technical tour of the Isogo Thermal Power Plant in Yokohama, Japan, with the IEA Working Party on Fossil Fuels in 2017;
  • Organised a workshop on facilitating HELE technologies in Tokyo, followed by a site visit to 2 thermal power plants in Isogo and Yokohama, Japan, in 2016; and
  • Organised two workshops in May and July 2015 in Turkey, which focused on clean coal technology and the barriers to deployment.
