a k vasi diskusi o vodiku v australii:

---jeden z projektu(je jich nekolik v tyhle oblasti) - The Asian Renewable Energy Hub - 2028:
The proposed project includes:
26 GW of wind and solar generation
At least 3 GW of generation capacity for Pilbara energy users
Up to 23 GW of generation for production of green hydrogen and green ammonia
Up to 100 TWh of total annual generation
A design life of 50+ years

From a 14,000-square kilometre initial land package, 6,500 square kilometres of land in the East Pilbara region of Western Australia were selected to accommodate 26,000 MW of wind turbines and solar photovoltaic panels. Outstanding wind and solar resource and large project scale will result in competitively priced renewable energy with a high capacity factor.


---dalsi projekt (The Arrowsmith Hydrogen Project) ten by mel byt v provozu koncem 2022
The plant would be supplied by around 85 megawatts of solar power, supplemented by 75 megawatts of wind generation capacity, which will be generated on-site. The project would also integrate a large-scale battery on-site.

Green Hydrogen Sub-commercial Plant #1
Stage One of the IBE Liquid Hydrogen Project will be the Arrowsmith Project, located in Western Australia. This installation will commence production in 2022 resulting in 25 tons (25,000 kg) of green Hydrogen per day from the zero carbon energy sources of water, solar and wind.

Green Hydrogen Commercial Plant #2
(Capacity 75,000Kg/day)

SEJDA: "Kdyby se vam zle predstavovalo, co je to 50ha, tak je to asi tolik"

uhm, tohle ze je 700x700m?

v clanku:
"Floating solar installations at the dam, which will resemble those in this image"
"“The [floating PV] project will occupy a total area of about 50 hectares of water surface and will require over 127,000 PV panels "

DZODZO: no prece, ze elektrolyzovat muzou i arabove, takze proc by to melo byt vsechno v australii? :)

SEJDA: kurva elegantni reseni jak udrzet v rezervoaru pitnou vodu

Kdyby se vam zle predstavovalo, co je to 50ha, tak je to asi tolik:

Tender for 50 MW of floating solar launched in Portugal – pv magazine International
https://www.pv-magazine.com/2019/11/27/tender-for-50-mw-of-floating-solar-launched-in-portugal/

DZODZO: vzdyt uz jsem ti to spocital: SHEFIK odhaduje 200 GWh energie na vyrobu C-H2 (asi elektrolyza vody), to je pri 2MWh z kazdeho m2 za rok, jenom 10 ha solarnich panelu, tedy pokud ti bude stacit tu lod nabit jednou za rok. Pokud se otoci 3x, tak potrebujes 30 ha, no s nejakyma mezerama atp. 50 ha. 573 km2 je pri 50 % vyuziti plochy neco jako 573 TWh, tj. jako 3000 tech lodi?
Delam nekde radovou chybu, anebo jenom ty nevis, ze se do 1 km2 vejde 100 hektaru?

SEJDA: ok tu som ti to zakreslil hned pre vsetky obchodne lode sveta, inymi slovami stale nechapem tu narazku na to "tak si to vypocitaj", ze co tym sledujes, ze ci je to jako hodne alebo jako malo

New Zealand Designer Makes Ingenious Solar-Powered Skylight That Desalinates Water For Drinking
https://www.goodnewsnetwork.org/...esalination-still-by-henry-goglau-purifies-water-and-makes-light/

Goglau’s device can purify 440 milliliters of water a day, with leftover brine being sifted into batteries made of zinc and copper where they power an LED strip for use during the night.

finalist in the 2021 Lexus Design Award, Henry Glogau, has created something that takes advantage of both these abundant resources: a solar-powered lighting fixture that desalinates water.

Nekonečná téma "psychológie klimatickej krízy". Je notoricky známe, že široká verejnosť hrubo podceňuje (ignoruje/zlahčuje/zosmiešňuje/relativizuje) následky oteplovania. Čo si niektorí zase interprerujú tak, že "klimatológovia desaťročia neúspešne strašia", veď inak by sme už všetci chápali, že Houston má problém.

Príčin, prečo dlohodobo nie sme schopní racionálne reagovať (individuálne ani kolektívne) na túto existenčnú hrozbu, je viacero. V zásade ide o súbor nevedomých, evolučne podmienených inštinktov, ktoré našim predkom, a ich predkom (až smerom k prvému živému organizmu), zabezpečili prežitie v nekonečnom konkurenčnom darwinovom boji "prežitia silnejšieho", ak chcete inak, automatickej reakcie, ktorú nedokážeme svojou "slobodnou vôlou" (tj. vedomým rozhodnutím) ovplyvniť.

A tak, vo svetle najväčšej ekologickej hrozby histórie ludstva "slepo" kráčame k pomyslnému útesu. Hladáme si rôzne výhovorky, prečo útes neexistuje (popieranie klimatickej krízy), alebo "riešenia" ako pád z útesu prežijeme (technooptimizmus/odletíme na Mars). To všetko len odráža našu nemožnosť (nie neschopnosť) racionálne reagovať tak, ako je potrebné.

Psychológovia budú hladať cesty, ako von zo "začarovaného kruhu", ale je to podobné, ako sa snažiť pochopiť, prečo papagáj nerozumie teórii relativity (bez urážky) a potom sa snažiť mu ju vysvetliť.

Klimatická kríza je neriešitelný problém.

SHEFIK: Tak to spocitej, kolik ha solaru na to potrebujes ..

TADEAS: to znamena, ze renewables musi v australii vyrobit neco jako 200gwh na jednu lod. tech lodi ve vysledku asi moc potreba nebude :)

SHEFIK: 2000 tun by melo bejt neco jako 66.6 GWh ,)

tak snad do slibenejch 5ti let

Australian green hydrogen vessel deemed ‘highly competitive’ – pv magazine International
https://www.pv-magazine.com/2021/03/02/australian-green-hydrogen-vessel-deemed-highly-competitive/

The “world first” vessel design, which has already been patented, will be able to transport 2,000 tons of compressed hydrogen. GEV, a marine transport company based in Western Australia, says the study confirms that it can deliver the ship itself and a full zero-emissions compressed hydrogen (C-H2) supply chain with minimal barriers. It expects commercialization within the next five years.

...

The C-H2 Ship can carry up to 2,000 tons of hydrogen in its containment system. The company has said that its design “eliminates the requirement for onsite storage, as the C-H2 Ship is itself the storage.” It has described its push to develop a compressed hydrogen ship as a “natural progression to meet a market requirement for the storage and marine transportation of hydrogen.” 

GEV said the scoping study shows that its compressed hydrogen supply chain is economically “very competitive” compared to shipping liquefied hydrogen or ammonia at distances of 2,000 nautical miles (3,700 km). As the company noted, that is roughly the distance between  northern Australia and Singapore. Its C-H2 shipping remains competitive to 4,500 nautical miles, which is the distance from Australia to Japan, South Korea, and China.
