The global trends drive energy market trends



• More energy

• More affordable energy

• More affordable and safe energy

• More affordable, safe, and clean energy



• CO2 out of the energy system

• Energy efficiency gaining momentum

• Sector coupling + Energy Storage

• The energy system is getting more complex

• Digitalization is the key to handle the complexity and create new

customer value and profit pools / New business models emerging

• Technology / investment ↑ ➔ cost ↓ ➔ dynamics changes

• Need to manage the stranded fossil assets appropriately

• Geo-politics and governments play key roles

• More energy

• More affordable energy

• More affordable and safe energy

• More affordable, safe, and clean energy

Core Technologies for future are Low Carbon, Sector Coupling and Digitalization technology

Energiewende 2.0

1) Corrective action to avoid bottlenecks in power grid


The new energy world: fully electrified, more complex and with

renewable energy provision that is decoupled from consumption

(PV) + (Wind) – (Consumption) = (Residual Load) = f(t)(PV) + (Wind) – (Consumption) = (Residual Load) = f(t)

Definition

• Link between power sector and energy-consuming sectors

• Crucial to reach deep decarbonization of the energy sector

(-80 … 95%)

Value Proposition

• Higher overall energy efficiency

• Supports supply/load balancing in case of high share

of intermittent renewable generation

• More diverse and interdependent energy supply

Drivers

• Reduction of GHG emission

• Energy efficiency improvement

• Reduction of energy import dependency

• Integration of volatile Renewables

• Technology development

(e.g. e-mobility, battery, hydrolyzer)

Sector Coupling


In a Sector Coupling approach, the increased

electrification reduces primary energy consumption
