Storage

Is there anything to learn from storage approaches in other domains?

Abstraction Analogy

Principle 1: Segmentation

• The Segmentation principle for encourages considering dividing an object into smaller independent parts,

• making an object sectional,

• making an object easy to assemble or disassemble,

• increasing the degree of an object’s divisibility or fragmentation.

Segmentation

Segmentation

Parameters and principles

• What do we want to improve?

• Duration of action by a stationary object (16)

• Temperature

• Use of energy by stationary object (20)

• What gets worse?

• Volume of stationary object (8)

• Loss of Energy

• Device complexity

Parameters 8 and 16 → Principles 35, 34, 38

35 Transforming the physical or chemical

state of an object

34 Discard and renewal

38 Strong oxidants

Decision Making

• Functional Modelling

• Design Rationale

• Problem Structuring Methods (PSM)

Clever gadgetry?

• Passive active

• Active TES

• Segmentation and modularisation

• Incorporation of TES in building elements

• Retrofitting

• High temperature TES; Conventional TES; Cold TES

• Use of high tech to address the stability and life of PCMs

• Play the Grid
