Christian Breyer

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, reflecting sustainability and climate targets. 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 240 in scientific journals. As of March 2025 he has 263 Scopus listed publications, received more than 17,800 citations (Scopus) with an h-index of 73 (Scopus) and more than 28,300 citations (Google Scholar) and an h-index of 88 (Google Scholar). 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, reviewer for the IPCC, member of the national Finnish IPCC working group, 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 BSky @ChristianOnRE.
