LUT University, Finland
Christian Breyer is Professor for Solar Economy at LUT University, Finland. His major expertise is the integrated research of technological and economic characteristics of renewable energy systems specialising in energy system modeling for 100% renewable energy, on a local but also global scale. His team published the most studies on 100% renewable energy systems for countries or major regions globally. Energy system transition studies are carried out in full hourly and high geo-spatial resolution. Publications cover integrated sector analyses with power, heat, transport, desalination, industry and negative CO2 emission options. Power-to-X investigations is a core research field for his team. He published more than 300 scientific papers, thereof more than 130 in scientific journals. He worked previously for Reiner Lemoine Institut, Berlin, and Q-Cells (now: Hanwha Q Cells). He is member of ETIP PV, IEA-PVPS, scientific committee of the EU PVSEC and IRES, scientific advisory board of CO2 Value Europe, academic council of Global Alliance Powerfuels, chairman for renewable energy at the Energy Watch Group, member of the National Finnish IPCC group, reviewer for the IPCC and a co-founder of the Desertec Foundation. His academic background is general business, physics and energy systems engineering and a PhD in electrical engineering. He communicates in Twitter @ChristianOnRE.
The energy transition is accelerating pace, driven by climate emergency, very high energy prices and overall interests in raising sustainability and resilience of energy supply. Consensus is growing that renewable electricity will play a major role in the ongoing transition, along higher levels of electrification. Various scenarios project zero greenhouse gas emissions around mid-century, as it is required for the 1.5⁰C target of the Paris Agreement. Most ambitious scenarios project a near 100% renewable energy system by mid-century. This implies massive electrification for various applications, while hard-to-abate segments of the energy system require solutions based on energy-dense molecular energy carriers, which practically all are related to hydrogen. This indirect electrification mainly applies to fuels for marine and aviation transportation, chemical industry, steelmaking, among others. Thus, renewable electricity and hydrogen emerge to the inner core of the new energy system. The various electricity-based solutions are summarised as Power-to-X and the hydrogen-based solutions are grouped to green hydrogen. An optimised energy system operation integrates the benefits of low-cost renewable electricity, and the flexibility of hydrogen production. The presentation will cover the background on the energy transition, the key elements of an energy system characterised by Power-to-X, and the central role of hydrogen in capacity, energy throughout and operation to achieve a fossil free society.
