Elektrienergia tarbimise, taastuvenergiaallikate kasutamise ja elektriautode tootmise tõusev
trend on peamised põhjused, mis on teinud elektrienergia salvestustehnoloogiate
kasutamise ja arendustöö oluliseks teemaks ühiskonnas. Antud bakalaureusetöö eesmärk
on selgitada välja elektrienergia salvestustehnoloogiate hetkeseis.
Töötsükli kestvuse järgi on jaotatud elektrienergia salvestustehnoloogiad kolme gruppi:
lühiajalise, pikaajalise ja ülipikaajalise töötsükliga salvestustehnoloogiad. Lühiajalise
töötsükliga salvestitest on kirjeldatud hooratas-energiasalvestit ja ülikondensaatorit. Kui
enamus hooratas-energiasalvesteid leiab kasutust lühiajalise autonoomse toiteallikana, siis
ettevõte Amber Kinetics on arendanud mudeli M32, mida on võimalik neljatunnise
tühjenemisajaga rakendada ka pikaajalise töötsükli perioodiga kasutuseesmärkidel.
Ülikondensaatori kõige potentsiaalsem arendus lähiajal on kombinatsioon mõne
elektrokeemilise elektrienergia salvestustehnoloogiaga. Pikajaline töötsükkel on peamiselt
elektrokeemilistel elektrienergia salvestustehnoloogiatel, millest on populaarseimad
pliiakud ja liitiumioonakud. Ülipikaajalise töötsükliga elektrienergia
salvestustehnoloogiatest leiab enim kasutust pumphüdroakumulatsioonijaam.
The rising trend of electrical energy consuming, renewable energy usage and electric vehicle production are the main reasons why electrical energy storage technologies have become an important issue in our society. The aim of this thesis is to find out the current state of electrical energy storage technologies. According to the duration of the operating cycle, energy storage technologies are categorised into three: short term, daily term, and long term. Flywheel storage and ultracapacitor are the main short term operating cycle systems. As most flywheel energy storage systems are used as short term uninterruptible power source, the manufacturer Amber Kinetics has developed model M32 that has 4 hour discharge duration, which can also be applied as daily term storage system. The most promising development of ultracapacitor is its combination with electrochemical electrical energy storage. Electrochemical electrical energy storages are used mainly as daily term operating cycle systems, the main being lead-acid and lithium-ion battery storages. The most common long term operating cycle storage technology is pump hydroelectric energy storage.
