TASK 69: Solar Hot Water for 2030

The purpose of the Task is to investigate which technologies are the most appropriate now and into 2030 for solar-derived hot water, considering the full spectrum of global economic development. The Task will predominately focus on the development path and best practices for two technologies which, we believe, are likely to play the biggest role in the solar hot water market in 2030: solar thermal thermosyphon systems and solar photovoltaic (PV) self-consumption hot water heating systems. Both technologies avoid pumped circulation, require little maintenance, and have relatively low up-front capital costs, so they will clearly be strong contenders for deployment in 2030. Both technologies also offer the potential for further development, via innovative ‘smart’ control systems and real-time monitoring and integration with other residential and commercial energy systems.

IEA Solar Heating & Cooling Technology Collaboration Programme

The Solar Heating and Cooling Technology Collaboration Programme (SHC TCP) was established in 1977, one of the first programmes of the International Energy Agency, to promote the use of all aspects of solar thermal energy. The SHC TCP's work is unique in that it is accomplished through the international collaborative effort of experts from member countries and the European Union.

The benefits of this approach are:

  • accelerates the pace of technology development
  • promotes standardization
  • enhances national R&D programmes
  • permits national specialization
  • saves time and money

Solar Heat Integrations in Industrial Processes

Solar Heat for Industrial Processes (SHIP) is at the early stages of development but is considered to have enormous potential for solar thermal applications. The industrial sector accounts for approximately 30% of the total energy consumption  in OECD countries. And, the major share of the energy needed in this sector is used for heating and cooling buildings and production processes at temperatures from ambient up to approximately 350°C. This is a temperature range that can be addressed with solar thermal technologies. -- View PDF
