MN-00-16-2 -- Contribution of Stratified Thermal Storage to Cost-Effective Trigeneration Project PDF

The trigeneration plant for Expo '98 in Lisbon, Portugal, provides electricity, heat, and refrigeration, three energy products, from the same energy source, i.e., gas-thus the term "trigeneration"-and incorporates a number of innovations, including a stratified chilled water thermal energy storage system, the largest to date in Europe. The entire project was completed on a fast-track basis, commissioned, and brought into operation long before the opening of the World Fair. The innovations contributed very substantial savings in both investment and operating costs; the stratified storage system was particularly important in achieving such reductions.
