Ülevaade
Energia tootmise üks põhieesmärk on protsesside efektiivistamine ja heitmete, sh. süsinikdioksiidi heitkoguste vähendamine. Ühe võimalusena uurib uurimisrühm põlevkivi ja biomassi koospõletamise võimalusi nt. tsirkuleeriva keevkihi (CFB) katlas. Kavandatud protsess võimaldab vähendada lisaks heitmetele ka ohtlike jäätmete tuhaprodukte, mida on senini igal aastal tekkinud ligikaudu kuus miljonit tonni. Ühe olulisema teemana tegeleb uurimisrühm süsiniku püüdmise ja ladustamise või kasutamise ehk nn. CCUS tehnoloogiate kasutusvõimaluste uurimisega. Põhiliseks eesmärgiks on uurida kas hapniku ja CO2 põlemise tingimuste rakendamisel on võimalik saavutada piisava puhtusega CO2 voog, mida saaks energiatootmise ringlusest välja juhtida, saavutamaks kliimaneutraalsust. Lisaks uuritakse võimalusi moodustunud tuha tõhusamaks kasutamiseks. Selleks uuritakse tuhkade sorptsioonilisi omadusi ja käitumist anorgaanilise aine tuhkade proovidest. Uuringuteks on kasutada tänapäevane infrastruktuur: 60kW CFB katseseade, TGA / DSC-MS, LA-ICP-MS, WD-röntgenanalüsaator, gaasi adsorptsioon analüsaator, osakeste eripinna ja poorsuse määramise seade (Quantachrome Autosorb iQ-C), elementanalüsaatorid (CHNS ja O), jne.Uurimisrühma käsutuses on akrediteeritud teaduslaboratoorium, mis võimaldab välja anda sertifitseeritud analüüsitulemusi erinevate kliente toodud erinevate iseloomudega proovidele. Samuti on labor akrediteeritud statsionaarsete saasteallikate õhuemissioonide määramise valdkonnas.
