Abstract
Climate change imposes significant costs on society, making new ways to produce and store energy increasingly important. This thesis explores a conceptual, renewable-powered hybrid energy storage system. The concept links four processes: electrolysis (splitting water into hydrogen), biomass gasification (converting biomass into gas), the Allam cycle (a specific power-generation process), and methanol synthesis. The system was modeled in Aspen Plus as two separate simulations. The simulations produced a stream of pure hydrogen and a high-purity methanol stream. A techno-economic analysis found promising potential product sales but an overall negative net value, indicating that cost reductions and further optimization are needed before the system can be economically viable.
Klimaforandringer medfører betydelige omkostninger for samfundet, og nye måder at producere og lagre energi på bliver derfor stadig vigtigere. Denne afhandling undersøger et konceptuelt, vedvarende drevet, hybridt energilagringssystem. Konceptet kobler fire processer: elektrolyse (opdeling af vand til brint), forgasning af biomasse (omdannelse af biomasse til gas), Allam-cyklussen (en specifik kraftproduktionsproces) og methanolsynthese. Systemet blev modelleret i Aspen Plus som to separate simuleringer. Simuleringerne gav en strøm af ren brint og en højren strøm af methanol. En teknisk-økonomisk analyse viste lovende salgsmuligheder, men en samlet negativ nettoværdi, hvilket peger på behov for omkostningsreduktion og yderligere optimering, før systemet kan blive økonomisk levedygtigt.
