Jeg er professor i fornybar energi ved NMBU hvor jeg forsker jeg på økonomiske spørsmål knyttet til energimarkedet og særlig klimavennlige energiløsninger. Jeg jobber spesielt med hvordan vi kan gjøre energisektoren mer klimavennlig, men samtidig lønnsom ved bruk av fornybare energikilder, og hvordan vi utvikler et energisystem for framtiden som er fleksibelt nok til å tåle store mengder fornybar kraft. Jeg arbeider også mye med marked- og virkemiddelanalyser. Forskningen min omfatter:
- Framtidsscenarier for energiproduksjon og energipriser
- Lønnsomhetanalyser for fornybar energi
- Effekter på det nordiske energisystemet av den europeiske energiomleggingen
- Effekter av økonomiske virkemidler for utbygging av fornybar energi
- Løsninger for et fleksibelt samspill mellom kraft- og varmesektoren
- Bioenergiens rolle i framtidens energisystem

Forskning & prosjekt
Prosjekter
We will improve forest resilience to climate change, and contribute to reduced GHG emissions by substituting fossil based products with forest products, and at the same time, provide increased and sustainable economic returns to forest owners.
Vi skal utvikle verktøy som forbedrer skogens motstandsevne mot klimaendringer og som bidrar til reduserte klimagassutslipp ved å erstatte fossilbaserte produkter med skogprodukter, og som samtidig gir økt og bærekraftig avkastning for skogeieren.
NorENS vil utforske de sannsynlige retningene av den europeiske energiomstillingen. Prosjektet vil utvikle fremtidsorienterte analysemodeller som forbinder all fleksibilitetsteknologi i kraft-, varme-, gass- og transportsektoren.
NorENS will explore the likely directions of the European energy transition. It will develop future-oriented analysis models that connect all flexibility technologies in the power, heat, gas and transport sectors.
Forskningsprosjektet BioNEXT analyserer premissene hva som skal til for at Norges fremtidige bioenergiproduksjon skal bli lønnsom og effektiv.
