Eesti on võtnud endale eesmärgiks, et aastaks 2030 pärineks kogu riigis tarbitav elekter taasutavatest energiaallikatest. Milliseid muudatusi on vaja ellu viia, et taastuvenergiale üle minna ning kas sellega on liiga hiljaks jäädud., räägivad Kliimaministeeriumi energeetika osakonna juhataja Rein Vaks ning Energiasalve juhatuse esimees Peep Siitam.
Energiasalvestussüsteemid. Kodusele päikesejaamale aku lisamine võimaldab salvestatud päikeseenergiat kasutada siis, kui päike ei paista. Kodune energiasalvestussüsteem vähendab sinu sõltuvust suurest elektrivõrgust ja tagab energiaga varustatuse ka elektrikatkestuse korral.

Hoorattaga energia salvestamine. Hoorattaga energia salvestamise (FES) tööpõhimõte on rootori kiirendamine suurele kiirusele (keerlev ratas või hooratas) ja energia hoidmine pöörlemisenergiana. Tehnoloogia alustest on lihtne aru saada kui kujutlete ennast keerutamas, hoides käes rasket kotti – kotist lahti lastes lendab see eemale ...
UHPC is a relatively new generation of cementitious material with very high strength, ductility and durability [7] g. 1 shows that, UHPC strengthened with fiber can be treated as a combination of three concrete technologies of self-compacting concrete (SCC), fiber reinforced concrete (FRC) and high-performance concrete (HPC) [8].
Over the last twenty years, remarkable advances have taken place in the research and application of ultra-high performance concrete (UHPC), which exhibits outstanding mechanical properties and excellent durability. It has shown great potential for the next generation infrastructure construction from the sustainability point of view. This paper will …
Despite the superior properties of UHPC, its application is limited because of the relatively high cost due to the use of relatively large quantities of silica fume [20] and cement. This can be observed in Table 1 for the mix design reported for a commercial UHPC mix (BSI®) [21]..

By exposing UHPC to a temperature ranging from 1000–1200 C, physical and chemical changes occurred in the UHPC matrix, resulting in disintegration mainly due to these alterations. The main reason for disintegration in UHPC structures is exposure to final elevated temperature, blasting, and previous exposure to fire [ 105 ].
Eesti esimene suuremahuline elektrienergia salvestamise projekt ehk Energiasalv on saanud rohelise tule ehituseks, millega hakatakse pihta 2024. aasta suvel. Mida projekt endast ette kujutab ning mida see energiaturul endaga kaasa toob, räägib Energiasalve juhatuse esimees Peep Siitam.

The water absorption of UHPC-NSC made with nano-particles was 36% lower than that of the reference mixture. The gas permeability coefficient of UHPC was found to be less than 1.0 × 10-19, which is almost three orders of magnitude lower than that of the CC [46].The lower capillary porosity of UHPC can reduce the capillary suction and intrusion of …
The development of ultra-high performance concrete (UHPC) with lower carbon emission has conducted by many researchers. However, there is a lack of quantitative comparison of carbon reduction efficiency, such as carbon emission and energy consumption values, of UHPC materials with various components.

Pealegi võimaldaks energia vesinikku salvestamine muuta tuule- ja päikeseparkide toodangu juhitavaks. Hoolimata vesiniku heast mainest ei ole selle tootmiseni, rääkimata kasutamisest, Eestis jõutud. „Vesiniku tootmise võimsust luua on ebamõistlik, kui ei ole toetavat taristut ja tarbijaid, ning tarbimist on keeruline arendada, kui pole ...
