Ah is a measure of Coulombs or charge (A × h = C/s × hr × 3600s/hr = C). Wh is a measure of Joules or energy (W × h = J/s × hr × 3600s/hr = J).

As an electrical engineer, personally Joules would make sense in an idealistic way to describe how much energy batteries store because that’s what they do, but the whole Ah/Wh framework simplifies calculations and makes it so you only really need to multiply, never divide.

I never really understood the focus on Amps as your primary unit to describe load on a system. It seems like NASA used to describe things this way when designing rockets/spaceships/landers for outer space/Moon missions. I remember listening to a podcast where NASA would budget their systems in terms of Amps, where you only had so much overhead in Amps.

Growing up as an EE in school and industry, Watts (and Volt-Amperes) is obviously the primary choice of metric, whether working in DC or AC.

So yeah I agree with you lol

Dems are chasing Repubs, so either party winning won’t really change this fact.

With Dems we’re delaying this outcome. With Repubs we’re accelerating it.

Unfortunately I think casting away Kamala as the pick would do more harm than good. She is the likely candidate. Joe can even make the transition smooth by entrusting the rest of his legacy with her, which is the reason he chose her as a VP in the first place.

People also know the name Kamala Harris, and they’ve known it for years now. It’ll be a huge turn to bring in a new candidate on top and do all of the rallying needed to get votes.

I think Kamala’s success will spend on the VP choice, her administration, and her campaign team more than her herself.

Mark Kelly as Kamala’s VP? Having that balance of ethnicity would help her get the votes. It’s exactly why Obama picked Biden

I mean, if anything, the fact that the Oil & Gas industry uses hydrogen for refining means that there is a possible, robust market for green hydrogen to get into (don’t like this because it means oil is still the focus, when we need to consider green chemistry and stop with oil).

The O&G industry also helped usher in solar PV at an early stage because of the needs of remote power in hazardous environments such as offshore rigs and near potential sources of release like oil tanks (I used to work as an engineer in O&G myself).

There’s actually a lot of work by GE and Mitsubishi to start shipping new gas turbines to be capable of firing a non-zero amount of hydrogen in addition to natural gas. I think some plants are even capable of doing 50/50 hydrogen/natural gas, with that former number increasing year over year.

Hydrogen could outstrip conventional fuels someday. The bottleneck has always been supply though.

If renewables are so abundant and cheap, then we’ll finally have a reason to deploy hydrogen infrastructure on a massive scale (at least in the US). Hell, you look at the major inverter manufacturers for utility PV like Sungrow, and they have containerized electrolyzers ready for implementation. I haven’t done a market survey, but if they’re in the game, then so are other players.

If you want to be convinced of the progress of hydrogen, I would look into the project that Sargent & Lundy is working on in Utah. They’re planning on using a salt cavern for hydrogen storage, and I believe there is a CCGT onsite as well to make use of the generation.

Hydrogen is even on the minds of offshore wind developers like Siemens.

The substance isn’t doomed like others in this thread make it out. There is active interest in the market to develop a supply chain and economy.

Edit: The one thing I don’t see a lot of people talk about though is where the raw materials for this hydrogen will come from… Likely groundwater unfortunately. Since groundwater is already a highly sought after resource for consumption and agriculture, I’m not sure if hydrogen in this way will take off. This is why offshore hydrogen seems to be more promising, but as we see with wave and tidal power, the ocean environment just sucks for any commercialization.

It’s an uphill battle, but the same can be said for the climate crisis in general. Hope we make enough progress before it’s too late.

Locking hydrogen up in ammonia is what the industry looks to be moving to to avoid the problem you describe.

Also, look up the 7 Hydrogen Hubs in the US as an example of this market getting started. There are no downsides to developing a hydrogen market if we’re going to have oodles of excess renewable energy.

Oil & Gas companies didn’t want Solar, Wind, and Storage to proliferate, yet they did because of cost savings.

I think we could start to see that for these alternative-ion batteries if lithium supply ever becomes an issue. There will always be a niche that has the opportunity to grow in the economy. Just takes the right circumstances and preparation

Really hope green hydrogen kicks off. Could begin society’s efuel saga

Redox flow, sodium ion, iron air, etc.

There are some 600+ current chemical-based battery technologies out there.

Hell for me, once sodium is cracked, that shit is so abundant that production wouldn’t have many bottlenecks to get started.

I found out this trick when I eating dinner once at my local library. Oddly, it was a kid came up and saw I was watching YT videos. Showed me the tactic, and now I rely on it lol

The billionaire class really flourished after Reagan eased taxes on the rich in the 80s. We need to go back to a time before him, but idk if that’s possible. Genie might be out of the bottle

Fuck

The only games I tend to play these days are the ones that I don’t have to update before playing. Such a nuisance to be always online.

Content creator branding, and “community”

This hurts me so much: it’s why I revert to text messaging because everyone has a phone number. The only downside is that you can’t add/remove numbers to existing groups, so it can get out of hand quickly with the number of group chats.

Yeah if I ever come across this experience, I just click on the name of the file that I already downloaded. Comes up and no need for redownloading.

Insert any good where any country doesn’t source it themselves.
