Eurooppa on samaan aikaan ihanne ja samaan aikaan totta. Ei pidä laskea mitään ulkopuolisen tuen varaan. Lähimmät ystävämme ja Ukrainan ystävät löytyvät läheltä.

Read the article and come back to me afterwords.

Grow up and read it again. It’s not against wind and solar and none of it is climate change denying.

Long term storage need is least of our worries if we truely care about climate. We need fuels to store only for couple of weeks in the year (5-10% of demand). At first we can use fossil fuels, then biofuels and after 20-25 years we have more options than hydrogen.

Depends on the value of the biofuels. There’s huge amount of biofuels than can be first and foremost freed from road traffic. Then we have other options too.
In reality, if you read any of that article hydrogen will never be cheap enough to scale for the demand.

Welcome to the new world order. Hallelujah.

I'm on a same page when it comes to hydrogen demand.
After all the land transportation has electrified and ships and planes use biofuels around 80-120 Mt of h2-demand remains.
Perhaps, I would put more emphasis on fertilizer (ammonia) put that will not elevate the demand.

Sen lisäksi puhutaan muutamasta muustakin metallista, mineraalista, harvinaisista maametalleista ja fossiilisista polttoaineista, mutta on erittäin vaikea nähdä, että Ukrainalla olisi tämän perusteella "5 prosenttia maailman kriittisistä mineraaleista".

Indeed but the funny part is that Ukraine's minerals reserves are not that extraordinary.

Also on a small print it reads that many approvals for the project were issued in July 2022:
"We have therefore been ready to move forward for quite some time."

Portugali tosiaan mielenkiintoinen ja Ukrainassakin 16%. Huima lukema.

Indeed, well said. I’m going to use this saying later on

Better to go biofuel instead, like most of the saf will be procured.

Jos kaipaat vetykeskusteluun hypetyksen lisäksi myös ripauksen analyysitason realismia, niin käy lukemassa viime vuonna tekemäni Vetytalouden nykytila-analyysi tai vähintään sen yhteenveto ensimmäisellä sivulla. 5/5 sites.uwasa.fi/vepe/wp-cont...

4/ Sähkö on puhdasta myös Norjassa, tuulivoima tuottaa enemmän Pohjanmeren rannikolla ja sitä tasaavaa vesivoimaa on tarjolla mittavasti enemmän, mikä on vetytuotannon edullisuuden kannalta olennaista kuten tiedämme.

3/ Jos vety tosissaan korvaa öljyn, niin olettaisin, että rahaston likviditeettiä ohjattaisiin huomattavasti vetyyn, sillä houkuttelevaltahan tuo "10-kertaa Nokiaa isompi juttu" vaikuttaa. yle.fi/a/74-20117818

2/ Siksi on mielestäni olennaista kysyä, että aikovatko norjalaiset myös korvata öljyn vedyllä?
Aikovatko norjalaiset jatkaa rahastonsa kasvattamista vedyn avulla?

Näyttääkö tämä siltä, että Ukrainassa olisi 5% maailman kaikista kriittisistä mineraalivarannoista?

We will soon have 10 GW of wind and 3 GW of solar even though prices are already too low in the summer (bc of nuclear and solar). Everything after that is speculative and reliant on additional consumption but that is far from cursed location. Our national grid operator’s estimate:

It’s not a competition but everything happening on the ground counters your ”cursed” argument. Most of the wind power projects are currently 140 mean height. What is wind power ppa-price in Iceland?
comment in response to
post
We have the second lowest average electricity wholesale price in EU due to naturally developed wind power scheme (8 GW and counting-unsubsidized) last year. More than 60 GW of wind is planned. 3 GW of hydropower was build long time ago which is balancing the market. I wouldn't call that a curse.

That's it, but one more thing.
1⃣ We have enough economically recoverable minerals for the energy transition which means that
2⃣We don't need to mine the Greenland bottom up in -50°C temperatures.
It's up for inuit to decide what to do with their land and the country.

Nickel reserves remain the same. Indonesia mined 59% of the world's nickel last year which is in a league of its own. The next one on the list, Philippines, produced 9% (0,33 Mt).
comment in response to

Chile and copper is often mentioned but DRC was 2nd most largest producer of copper with 3,3 Mt last year (up 13%). Only 38% shy of Chilean production.
Copper reserves retracted 20 Mt, after 110 Mt hike in 2023. Mined output has increased from 20,6 to 23 Mt in five years.
comment in response to
post
Cobalt reserves have stayed the same which means that they has at least grown the mined output (0,29 Mt).
Global mined output is 2X what it was five years ago and the Democratic Republic of Congos's share of the production has increased from 68% to 76%.

Lithium reserves (economically recoverable minerals) are up 2,0 Mt likewise last year. Enough for around 250 million EVs.
Last year 17 million EVs were sold (PHEVs included).
Identified lithium resources has grown too like Dave mentions in his thread.

At the same time, global battery demand has increased from 0,3 to 1,25 TWh (320%) which might indicate the development of battery chemistries. Excluding copper and nickel, less virgin minerals are mined/kWh.
Lithium mine output has grown 3X but battery demand 4X from 2020.
comment in response to
post
Instead of mineral reserve growth, my attention is directed into significant and substantial growth of the mine production of these selected battery minerals.
From 2020 to 2024:
- Lithium mined output has grown 193%
- Cobalt 107%
- Nickel 48%
- Copper 15%

Todennäköisesti on silti edullisempaa ajaa moottorivoimaloita 4-6 viikkoa (8-12% käyttöaste) vuodessa osittain tuen avulla kuin maksaa kymmeniä vuosia tukea ydinvoimalle.
Vaihtoehtojen selvittämisen tarve on ilmeinen kuten mielipiteessä kirjoitetaan.
