The Energy Sector Transition From Fossil to Renewable

Source: 2017 DNV GL energy transition outlook – renewables, power, and energy use

The fossil share of the world’s primary energy mix will decline from 81% currently to approx. 50% in 2050

Significant increase ofnenewable

energy sources

Need to deal with the volatile energy sources

Electricity generation will increase rapidly globally

By 2050, well over 80% of the electricity will be

generated by renewable sources.

Solutions needed like

• demand shifting• storage

• sector coupling


Intelligent Hybrid Energy Distribution Systems – and Sector Coupling

▪ Virtual storage (Demand response) is the most cost effective solution. Requires digitalization (Smart grids) and interconnection of the systems (smart energy).

▪ The lowest cost energy storage system is pumped hydro power. Needs a robust grid for long distance transport of electricity.

▪ An effective method to reduce fossil fuels is to use renewable electric power for electromobility and heating & cooling systems with thermal storage.

▪ Battery storage systems are great for peak shaving and short term balancing.

▪ Power-to-gas systems can convert electric power to gas – and back again when needed.
