Techno-Economic Analysis (TEA)

• It is a method to evaluate the overall value of the economic performance of a technology, to objectively weigh the benefits and costs, and then evaluate its potential market.

• Common comparison aspects of TEA include cost, benefit, risk uncertainty and time frame, etc.

Learning Curve

• The learning curve is the tendency for unit costs to decrease as production volume increases.

• In the field of new energy technology, learning curves can be used to analyze and predict the cost decline rate of new energy technologies, evaluate the cost trends of different new energy technologies, and help policymakers and investors formulate relevant policies and investment strategies.

• The traditional single-factor learning curve model also has certain limitations. For example, the model assumes that the unit cost is determined by only a single factor of cumulative device capacity, while ignoring the influence of other factors.
