Candidates to disruptive energy technologies to form the basis for the future energy system

1) RenewablePowergenerationSolar, wind

2) Smart-grid &Electrical Energy Storages

3) Bridging technologiesP2H, P2X, heat pumps, fuel cells

4) CO2 extraction andefficient energy end useCO2 capture, desalination, e-mobility, LED:s, ICT in general providing flexibility and enabling energy efficiency

• Technology: hardware & software, price decreases and performance improves, the improvement is driven by the development of technology

A large portion of intermittent power generation requires all kind of flexibility into the energy system

• In future majority of electric power will go through the power electronics at least twice before consumed in the end applications

• Power electronics hosts algorithms and methods enabling energy efficiency, demand response, and smart grid

• ~5-10% share in the investment cost of disruptive energy technologies (part of those)

Learning rate: 18.9%Cost reductions driven by increasing power density

Energy efficiency solutions – a means to reduce the total cost energy transformation

• Not necessarily new technology, instead:• Systems approach to energy conversion chains• New design practices, correct dimensioning, real-time measurements, intelligent

control, etc• In general more electrification and variable speed drives

Conclusion

• We are in the middle of energy transition: “The electrification of the whole energy system”

• There are several visible signs of this transition; 1) wind and solar power are becoming the least cost electricity generation techniques, 2) the power generation is becoming more distributed (by location & ownership), 3) the cost of storing electric energy decreasing, 4) the proportion of electric vehicles is increasing, etc

• Hydrocarbons in the forms of fuels, chemical feeds, human foods and animal feeds are still needed. These have to be electrified also by power-to-x technologies

• Finland is both a target of disruption and can benefit from it, providing technology, services, and software:• Power electronics, energy efficiency solutions, P-to-X technologies• Forest industry is a large source of Bio-CO2 ,could be used as a raw

material for biofuels, bio-chemicals, bio-materials
