Haven’t checked in for at least six months. Obviously I haven’t missed anything. And yes, still a “Rossi skeptic”, a unicorn skeptic, a Santa Claus skeptic….

Energy Vault’s First Grid-Scale Gravity Energy Storage System Is Near Complet
Energy Vault's First Grid-Scale Gravity Energy Storage System Is Near CompleteBecause concrete is denser than water, it takes more energy to elevate it, but that means it’s storing more energy too.singularityhub.comSwiss startup Energy Vault came out of stealth mode in 2018, and has been on an upward trajectory since then. The company created a system to store electricity by elevating concrete blocks, and investors quickly jumped on board: Energy Vault raised $110 million from the SoftBank Vision Fund in 2019, and another $100 million led by Prime Movers Lab in 2021. It seems they’ve put that funding to good use, because last week the company announced commissioning of their first grid-scale energy storage system outside Shanghai, China.
The system is like a solid version of pumped hydro, which uses surplus generating capacity to pump water uphill into a reservoir. When the water’s released it flows down through turbines, making them spin and generate energy

Haven't seen anything from BLP in quite a while. Not even a video. That is unusual for them. Could be a good sign, or bad. Anyone know what is going on?
material science hasn't caught up yet. Pretty hard to contain a star in a can.

The first is that it is mostly generated from fossil fuels, which does not make it helpful against climate change. When it is genuinely green, it is obtained through electrolysis, a process that is only 70% to 80% efficient. That's not bad compared to internal combustion engines (ICEs), but fuel cell detractors use that to bash them anyway. Scientists at Tel Aviv University plan to kill that argument with a method that is over 90% efficient in generating green hydrogen

The U.S. Could Leapfrog The World In Producing Clean Hydrogen—But Only If Treasury Encourages Diverse Investments
The U.S. Could Leapfrog The World In Producing Clean Hydrogen—But Only If Treasury Encourages Diverse InvestmentsTreasury must offer a policy framework that allows clean hydrogen to provide complementary benefits to other clean energy solutions for the US to compete…www.forbes.comIncreasing electrolyzed clean hydrogen production is key to the clean energy transition, long recognized for its potential to replace fossil fuels to decarbonize heavy industries, power vehicles and airplanes, generate electricity, and more. Producing it entails running an electric current through water to separate its constituent elements, hydrogen and oxygen, via a process called electrolysis, which takes place in an electrolyzer. If the electricity for the electrolyzer comes from zero-carbon resources like nuclear, hydropower, wind, solar, or fossil fuels with carbon emissions captured, the result is clean hydrogen, regardless of the technology deployed.
The challenge is, with the technologies available today, electrolyzed clean hydrogen is extremely expensive, costing about $4-8/kg to produce compared to about $1/kg for hydrogen produced from natural gas via steam methane reforming, which currently accounts for 95% of U.S. hydrogen production.

This is a 16 MW offshore turbine. The capacity factor of offshore turbines is around 40%, compared to 35% onshore. So this produces ~6.4 MW. The average nuclear plant is ~1 GW with a 93% capacity factor, so that's 930 MW. So it would take 145 of these turbines to produce about as much as one nuke.
I believe these turbines cost about $26 million to manufacture and install. 145 * $26 million = $3.8 billion. Or $4 million per megawatt of actual power (not nameplate). Compare this to the two new nukes being built in Georgia. They have cost $30 billion so far, with another year and several more billion to go. Nameplate capacity 2,200 MW, actual 2,046. That's ~$15 million per megawatt actual power. 3.8 times more. Plus you have to pay for uranium fuel (28% of operating cost) and decommissioning (which they charge the customers for each kilowatt hour, but I do not know how much).
You can see that only an insane power company executive would build a nuclear plant in a place where abundant wind or solar resources are available. Even with the extra cost of battery storage, no one pays 3.8 times more for electricity than they need to. You do not need 100% storage to cover wind intermittency or as backup during turbine maintenance. In a wide enough area, the wind always blows somewhere. For maintenance, wind turbines can be taken offline one at a time, so you do not need 100% wind farm capacity for backup. Whereas you do need 100% backup capacity for a nuclear plant. The entire plant shuts down for maintenance ~7% of the time, for several days, including peak hours. You need 100% of the nuke plant capacity standing by ready to replace it, with things like peak natural gas generators.
Wind turbines seldom go offline in accidents or at unexpected times. You can usually predict days ahead of time when wind will be low (or when there will not be much sunlight for a solar array). Output is more predictable and controlled than with a nuke plant. Nukes often shut down abruptly in SCRAM events.
https://www.nrc.gov/reactors/o…ps-experience/scrams.html
Most of these are caused by plumbing problems. Plumbing problems destroyed Three Mile Island.
An entire coal plant or natural gas plant can also also go offline abruptly. ~1 GW of power is lost suddenly. Nothing like that happens to a wind or solar installation. They are far more reliable than conventional fossil fuel or nuclear plants. It does not seem that way, because of intermittency. Right wing commentators who know nothing about energy often claim they are less reliable, but those people do not know what they are talking about. They blamed the 2021 Texas winter power outages on wind. In fact, the outages were caused by nukes and natural gas plants going offline because they were not winterized. Wind held up better in the end. There is not much wind in Texas in winter.

Does this affect storms cracks
A Cracked Piece of Metal Healed Itself in an Experiment That Stunned Scientists
A Cracked Piece of Metal Healed Itself in an Experiment That Stunned ScientistsFile this under 'That's not supposed to happen!': Scientists observed a metal healing itself, something never seen before.www.sciencealert.comWhat we have confirmed is that metals have their own intrinsic, natural ability to heal themselves, at least in the case of fatigue damage at the nanoscale."
These are exact conditions, and we don't know yet exactly how this is happening or how we can use it. However, if you think about the costs and effort required for repairing everything from bridges to engines to phones, there's no telling how much difference self-healing metals could make.
And while the observation is unprecedented, it's not wholly unexpected. In 2013, Texas A&M University materials scientist Michael Demkowicz worked on a study predicting that this kind of nanocrack healing could happen, driven by the tiny crystalline grains inside metals essentially shifting their boundaries in response to stress.

You said currently commercially viable. Hydrogen will never be competitive to alternative energy sources. LENR will. Hydrogen is an energy storage material not an energy source akin to fossil fuels. You must use highly material intensive technology powered by coal to produce the solar panels and wind turbines, you must then electrolyze water to produce it and then store it then use fuel cells containing expensive precious metals to convert it back to electricity but that’s only for grid apps. If you want to use it for transport you have to compress it, pipe it at extremely high pressures through metals which will become brittle or other materials which are not currently in significant use. The experts reporting to the board of the oil companies I know were completely negative about any potential commercial viability. Yes Toyota has a car which they sold how many? A few fuel busses exist for showboating. Perhaps you know more than the highly paid consultants reporting to the oil companies and if so, more power to you. We see a viable path forward only for nuclear of some form.
unfortunately your highly paid consultants ignore a world wide push to eliminate nuclear power. You have heard of the green movement? Consumers don't want to foot the bill to build the reactors and safety concerns haven't changed. Please explain how 2 watts of excess heat changes present day reality. I hope lenr pans out but I have yet to see the extra energy as scalable. If lenr does take a place in energy production it will be long after Im gone.

Here a Swiss map for severity of hail for once in 50 years :: https://www.bauernzeitung.ch/a…hr-schweizweit-ist-352410
dark red big balls...
Hail always is very local and 4x/100 is a high frequency for a specific location. But as the US map shows:: Climate change = 4x more often hail so far....
So all you need for PV is an insurance with a good premium.
In Florida, over the last month hail is almost a daily occurrence. My roof is lined in solar panels and so far no damage. Most of the hail is pea to golfball size but on occasion baseball size and bigger. I'm lucky, my panals are included in my homeowners insurance. I pay a little extra but in the long run could be worth it.

The goal is not to be a hero. It’s to provide another option for humanity. Hydrogen is not an energy source and never will be in the chemical sense. LENR is the only way hydrogen will be commercially viable. Show me a hydrogen energy solution that is currently commercially viable to use your own argument.
you are kidding right?

I hope in the future lenr becomes viable but till that happens wind and solar along with fuel cell, and battery tech are taking us to the future

That’s a very snooty response for the LENR forum. It’s the reason I work 28h a day. And in any case if you do the analysis the countries with higher solar and wind power actually have a higher carbon intensity so regardless of what we are developing or not, the point remains. Some form of nuclear will be the only way forward for humanity.
it's not snooty at all, it's present day reality, oh, and thanks for taking on my 28 hours a day to make things better. I just don't think it's heroic but I do agree some form of nuclear will be in the mix. Hydrogen is the future.

Solar farms are everywhere. Not just restricted to desert locations. Even if we assume there’s no risk for hail damage, we still have EOL disposal issues. This issue cannot be just swept under the rug. Solar and wind will be the energy source for a thriving civilization. The numbers don’t work. Why we have to debate this on LENR forum? This is not Solar pv forum. We are all here to provide a better solution for the world. Portable scalable dispatchable power will always win in a free market.
these are marketable technologies, what do you have?
