摘要: Abstract: Life-cycle assessment is an established tool for industrial ecology. An analysis of the energy use in chemical and other energy-intensive industries still under discussion this field. We argue that concept exergy can play a role ecology, using recent Norwegian power production policy question as illustration. The whether to build standard natural gas- or hydrogen-fired gas-turbine combined-cycle plant meet increased needs electricity Norway. Several indicators are relevant discussion, we calculate three based on calculations, proposed literature. renewability, efficiency, environmental compatibility. show how these be used evaluate paths sustainable two gas-fired plants. found plants were equivalent, judged by their renewability compatibility, but not efficiency. This indicator favored plant, possibly combination with carbon dioxide (CO2) sequestration depleted gas reservoir. suggested present situation such one may have choose general between high low indicator, opposite, efficiency indicator. importance was demonstrated example. It enables communication different professional groups. technological details, understood engineers, transposed meaningful aggregated decision makers.
