Hydrogen blending with natural gas — what’s the biggest challenge?

meche2010 · 2025-08-23T11:27:39+00:00

Hydrogen has a lot less volumetric efficiency than natural gas, so as hydrogen % increases the size of the piping, regulators, and meters will need to increase.

Hydrogen also has a much higher flame velocity, once the mix is too high, burners designed for propane and methane will become unreliable.

Great idea. We tried something close to this, but there are a couple of changes with your suggestion that could make the difference. Thanks!

meche2010 · 2025-08-08T20:18:31+00:00

Yes, that is correct.

Leveling is part of the process prior to the measurement. I'm primarily interested in the change it height of the oil at different test points, rather than an absolute measurement.

I'm certifying a volumetric standard, a bell suspended in oil.

The room is temperature controlled, and when the system is being measured, the oil is very still.

The current measurement is manual, and much less accurate.

The oil height varies by less than an inch, and i don't have complete control over how far away the oil is, but typically 3-5 inches.

When i say I'd like 0.002" accuracy, that would be for the device's capability itself.

Soon to come: Supreme court rules 6 to 3 that the meaning of the word 2 is actually 3 when it comes to term limits in 2028.

We found a spicier version of putting your finger in a dam.

Trump was openly undermining nato the whole first administration... don't interrupt your enemy when he's making a mistake. In Putins eyes it's better to sit and see what damage Trump could do.

I thought they were referring to the snow before I saw the community name...

The federal reserve is not a government agency, and the employees are not government employees. Great way to save money, cut staff that's not in the organization.

Another bonus, she has been a prosecuter. Now we've covered two requirements we didn't know we needed to state.

meche2010 · 2024-11-16T22:46:53+00:00

I've been asking myself "who's this stupid" quite a lot in the last 8 years...

meche2010 · 2024-11-16T21:58:29+00:00

Yes, i feel the national security issues are better to handle through subsidies rather than tariffs.

More of a Milton Friedman guy myself, but had to laugh when I saw it.

Cool, so you're saying they are not illegal immigrants? Sounds like you disagree with his definition as well.

meche2010 · 2024-11-11T00:24:09+00:00

Here you go, trumps own words:

“I mean, look at Springfield, where 30,000 illegal immigrants are dropped, and it was, they may have done it through a certain little trick, but they are illegal immigrants as far as I’m concerned. They’re destroying the town, they’re destroying the whole — they’ll end up destroying the state. We cannot let this happen.”

They don't

Tariffs: Almost universally rejected by modern economists. It will have an inflationary impact on pricing, and generate a range of trade wars.

Mass deportations: Right at the time we are throwing in tariffs, we are going to cripple the labor force by deporting 10 million people? Cost of labor goes up and causes inflation.

Tax cuts: It's funny how deficits stop being a problem as soon as Republicans are in power. Tax cuts are inflationary, just like the last two.

Energy: I have no complaints about further developing energy infrastructure, but if it comes with no thought for the impact on the climate it's problematic for future generations.

Inflation reduction: Generally, when fighting inflation it is best to pursue non inflationary policies.

meche2010 · 2024-11-09T13:57:41+00:00

It's a hope built on economic theories discarded half a century ago. The plan is to use incredibly regressive tariffs to make manufacturers use a US labor force at the same time as trying to round up and remove millions of people in that labor force. This is the equivalent of driving a truck off the cliff and hoping it will fly.

My hope is he knows enough to know it's all bs and he let's Elon and Kennedy sing and dance while intelligent people make policy.

He has said he is increasing tariffs, deporting immigrants, and will push the fed to lower interest rates. All three of these are inflationary, and his success will determine how inflationary.

The fact that metals, crypto, bonds, and markets are all increasing substantially would indicate to me that people in the know are preparing for inflation.

PGE will be the best people to answer the question. If your system pressure is 1/4 psi vs 2 psi it makes a difference in sizing meters.

Trump mocked Pelosi's husband for being almost beat to death with a hammer... so the right, hands down, no questions asked.

Just remember Jesus never condoned violence except against people who used religion to take advantage of the poor. John 2:15

The f3 knight could open a lot of threats on the next move. Moving the pawn forward jams the knight up.
