Solar Heat for Industrial Processes (SHIP) is currently at the early stages
of development. Less than 100 operating solar thermal systems for process heat
are reported worldwide, with a total capacity of about 24 MWth (34,000 m2). Most
of these systems are of an experimental nature, and are relatively small scale.
However, there is great potential for market and technological developments, as
28% of the overall energy demand in the EU27 countries originates in the
industrial sector, majority of this is heat of below 250oC.
According to a study (Ecoheatcool 2006), around 30% of the total industrial
heat demand is required at temperatures below 100oC and 57% of this demand is
required at temperatures below 400oC. The heat demand below 100oC could
theoretically be met with solar thermal systems using current technologies, if
suitable integration of the solar thermal system can be identified. With
technological development, more and more medium temperature applications, up to
400oC, will also become market feasible.
In several specific industry sectors, such as food, wine and beverages,
transport equipment, machinery, textiles, pulp and paper, the share of heat
demand at low and medium temperatures (below 250oC) is around 60% (POSHIP 2001).
Tapping into this potential would provide a significant solar contribution to
industrial energy requirements.
The methodology which has been developed in order to realize thermal energy
supply in industry with minimal greenhouse gas emissions is based on a three
- Technological Optimization of the processes (e.g. increased
heat and mass transfer, lower the process temperature) and solar
thermal system (e.g. operation of solar field, integration
schemes, control, safety issues etc.)
- System Optimization (enhancing energy efficiency using e.g.
Pinch Analysis for heat exchanger network for a total production
- Integration of renewable energy/solar thermal energy (based
on exergetic considerations)
