Initial situation<\/h2>\n\n\n\n

Most coun\u00adtries in the world want to decar\u00adbonize their indus\u00adtry in the next 20 years. In impor\u00adtant sec\u00adtors such as steel and met\u00adal pro\u00adduc\u00adtion and the chem\u00adi\u00adcal indus\u00adtry, as well as in large-scale trans\u00adport by ship, plane and truck, this will only be pos\u00adsi\u00adble with large quan\u00adti\u00adties of hydro\u00adgen (H2<\/sub>). How\u00adev\u00ader, hydro\u00adgen is only emis\u00adsion-free if the elec\u00adtric\u00adi\u00adty for elec\u00adtrol\u00ady\u00adsis and fur\u00adther pro\u00adcess\u00ading comes from renew\u00adable ener\u00adgy sources\u2014in which case we can speak of \u201cgreen hydro\u00adgen.\u201d <\/p>\n\n\n\n

But CO2<\/sub>-free hydro\u00adgen pro\u00adduc\u00adtion will only become more wide\u00adly usable if pro\u00adduc\u00adtion costs are low\u00adered. To this end, immense invest\u00adments are being made in the pro\u00adduc\u00adtion of green hydro\u00adgen by gov\u00adern\u00adments as well as pri\u00advate funds and investors. And here is where MR comes in. Hel\u00adton Hen\u00adrique Bez\u00ader\u00adra, MR\u2019s expert for elec\u00adtrol\u00ady\u00adsis, explains: \u201cWe advise oper\u00ada\u00adtors and investors from the plan\u00adning phase to the com\u00admis\u00adsion\u00ading of the plant. If we are involved in the process at an ear\u00adly stage, invest\u00adment costs can be sig\u00adnif\u00adi\u00adcant\u00adly reduced and the prof\u00aditabil\u00adi\u00adty as well as the ser\u00advice life of the plants can be increased.\u201d One way in which this is done is by solv\u00ading the input-volt\u00adage prob\u00adlem at the elec\u00adtrolyz\u00ader.<\/p>\n\n\n

The problem with electrolyzer operation<\/h2>\n\n\n\n

Elec\u00adtrolyz\u00aders that are fed with fluc\u00adtu\u00adat\u00ading ener\u00adgy from wind or pho\u00adto\u00advoltaics have to adjust their pro\u00adduc\u00adtion depend\u00ading on how much elec\u00adtric\u00adi\u00adty is avail\u00adable for them at any giv\u00aden time. Since almost all H2<\/sub> plants work with direct cur\u00adrent, the fluc\u00adtu\u00ada\u00adtions in hydro\u00adgen pro\u00adduc\u00adtion as well as age\u00ading of the elec\u00adtrolyt\u00adic cells caus\u00ades exces\u00adsive rec\u00adti\u00adfi\u00ader oper\u00ada\u00adtion. With spe\u00adcial\u00adized con\u00adcepts from MR, rec\u00adti\u00adfi\u00ader oper\u00ada\u00adtion can be opti\u00admized by con\u00adtrol\u00adling the input volt\u00adage. <\/p>\n\n\n\n

Satya\u00adjit Pandya, who works in pow\u00ader qual\u00adi\u00adty at MR, knows the prob\u00adlems this caus\u00ades: \u201cElec\u00adtrolyz\u00ader oper\u00ada\u00adtion with\u00adout appro\u00adpri\u00adate input volt\u00adage con\u00adtrol would lead to high\u00ader har\u00admon\u00adic and reac\u00adtive pow\u00ader require\u00adments,\u201d both of which must be com\u00adpen\u00adsat\u00aded by cost\u00adly fil\u00adters and expen\u00adsive com\u00adpen\u00adsa\u00adtion devices. In addi\u00adtion, poor\u00adly con\u00adtrolled input volt\u00adages dam\u00adage the sen\u00adsi\u00adtive cells in the elec\u00adtrolyz\u00ader and reduce its per\u00adfor\u00admance over its life cycle (so-called \u201cvolt\u00adage drop\u201d) lead\u00ading to a short\u00ader life of the plant over\u00adall.<\/p>\n\n\n\n

The vacuum on-load tap-changer as a solution<\/h2>\n\n\n\n

In this regard, MR offers a com\u00adbi\u00adna\u00adtion of vac\u00adu\u00adum on-load tap-chang\u00ader and thyris\u00adtor rec\u00adti\u00adfi\u00ader that has proven itself on the mar\u00adket for decades. \u201cOver the past 30 years, we have super\u00advised more than 40 hydro\u00adgen projects, so we know exact\u00adly what is impor\u00adtant in these plants,\u201d Pandya empha\u00adsizes. The vac\u00adu\u00adum on-load tap-chang\u00ader opti\u00admizes the steady-state volt\u00adage adjust\u00adment which, in turn, reduces the elec\u00adtri\u00adcal inter\u00adfer\u00adence loads and har\u00admon\u00adics in the sys\u00adtem by about 40 per\u00adcent.<\/p>\n\n\n\n

This accord\u00ading\u00adly low\u00aders the need for com\u00adpen\u00adsa\u00adtion by pow\u00ader qual\u00adi\u00adty man\u00adage\u00adment sys\u00adtems such as har\u00admon\u00adic fil\u00adters, there\u00adby reduc\u00ading invest\u00adment vol\u00adumes and oper\u00adat\u00ading costs. The same applies to reac\u00adtive-pow\u00ader com\u00adpen\u00adsa\u00adtion for which the vac\u00adu\u00adum on-load tap-chang\u00ader also achieves a reduc\u00adtion of 40 per\u00adcent. Fur\u00adther\u00admore, adds Bez\u00ader\u00adra, \u201cOur VACUTAP\u00ae on-load tap-chang\u00aders are main\u00adte\u00adnance-free up to 300,000 switch\u00ading oper\u00ada\u00adtions\u201d.<\/p>\n\n\n\n

And because this solu\u00adtion requires less hard\u00adware over\u00adall, the space required around the H2 plant is also reduced. Fur\u00adther\u00admore, the sen\u00adsi\u00adtive cells in the elec\u00adtrolyz\u00ader expe\u00adri\u00adence less stress due to the opti\u00admized volt\u00adage con\u00adtrol allow\u00ading the pow\u00ader fac\u00adtor of the plant to remain high over a long peri\u00adod of time with a soft\u00ader and slow\u00ader volt\u00adage drop. Bez\u00ader\u00adra points out anoth\u00ader advan\u00adtage: \u201cThe over\u00adall ser\u00advice life of the H2 plant is increased by years, which con\u00adsid\u00ader\u00adably increas\u00ades the prof\u00aditabil\u00adi\u00adty of the invest\u00adment!\u201d\u2002<\/p>\n\n\n\n
