2·2 days agoif you’re interested in heating only, then geo-solar hybrid might be better for you. the point is that excess heat from solar collector gets stored in soil near borehole, which can be used for heating in winter. solar heat also gets you hot water year round, and it can be made to work with heat pump or without

Technology@lemmy.world•A new liquid battery stores solar heat for weeksEnglish
1·2 days agoIt is a liquid that after irradiating stores that energy while still cold and can be made to release it in form of heat on demand. but also it’s low grade heat mostly useful for heating and not for electricity generation. It would be simpler to just build long range transmission lines or put energy intensive manufacturing near PV farm in sunny region

to make ammonia you need to have pv to turn light to electricity then make hydrogen out of it then make ammonia in haber process, each step generates losses and none are practical on small scale

4·11 days agoarticle says that hungarian dependence on russian oil went from sixty-ish% to almost 100% after 2022, and many countries started sourcing oil elsewhere, meaning they used to have other sources, but dropped them for some reason. this can be restarted
on top of druzhba, there is an oil pipeline called adria from croatian coast in omisalj that goes among other places to hungary. turkstream is for gas, but it’s not the only source for the grid, and there are lng ports on the adriatic coast, and all these pipelines also go to groningen gas field and norwegian shore and other places https://www.entsog.eu/sites/default/files/2018-10/ENTSOG_CAP_MAY2015_A0FORMAT.pdf

some goods and intermediates have large energy content, like, if you wanted to use energy from large pv farm in, say, morocco, then it might make more sense to ship bauxite in and aluminum bars out (it takes some 50MJ/kg to make aluminum)
simplicity of the system would be a factor in small, unattended installations like for space heating for single home
