Helium shortage and alternatives.

Leave a reply

I’ve come to discover that we have a major helium shortage. Helium is used in semiconductor manufacture, in MRIs, chemical chromatography, and low temperature refrigeration. I need it for leak checking, something we just started doing, a quality assurance test for our products and now a service. I’m not hit hard by the shortage, but some other industries are.

For gas chromatography, helium can be replaced by hydrogen, as discussed here. I was recently invited to a seminar on it. Hydrogen gives sharper peaks than helium, and slightly quicker residence times, but it has to be very pure. As it happens, We make hydrogen purifiers at REB Research, it’s our main product. These purifiers allow you to do chromatography, or brazing with low-cost, bottled hydrogen, and even with electrolysis hydrogen. The purifier is a one-time purchase, and then you can use low cost hydrogen. You will want to vent the output of the chromatograph; you use very little for chromatography, or brazing, ~50 cc/min typically, but without some venting, it can build up eventually.

Some testers have begun using natural gas for leak checking, I notice. It’s not a sensitive, and you have to make sure you’re vented so there isn’t a flame. A safer alternative is forming gas: 5% hydrogen in nitrogen. The leak sensitivity is low, well below that with helium, but above smoke, or smelly compounds.

A major cause of the helium draught is Biden’s sale, with congressional approval, June 24, 2024 of the Federal Helium Reserve. This was a massive underground stockpile of helium, 32 billion cubic feet, that filled a set of caverns that span three states. We’d managed the stockpile for years, with a monument too, see right, but Biden sold the entire reserve including 425 miles of piping, purifiers, and caverns to Messer LLC, a German company owned in China. See an NBC article about the sale, here. The price was $460 million, less than 1¢ per cubic foot of He, with the pipes, storage area, and purification facility thrown in for free. Messer LLC quickly sold off the helium to recoup their purchase, and now it’s gone.

The sale of the reserve would not have been so bad, but in March, the Iranian Revolutionary guard bombed Qatar’s Ras Laffan natural gas and helium plant, the world’s largest helium plant, doubling the spot price of helium, see. AP article here. Why does Iran, a Shia-Islamic republic, bomb plants in Qatar, another Shia Islamic republic? it’s a form of economic war. Russia is another major gas and helium producer, and I expect Ukraine will bomb Russia’s plants too. If you use helium for chromatography, you might want to switch to hydrogen, and invest in a purifier from REB Research.

The economic case for Alberta separatism

Leave a reply

Canada is poor relative to the US as I discussed in a previous post. Though they have lots of available land, home prices are very high, much higher than in the US because of regulations and fees. Similarly, it is hard to start a business in Canada, and salaries are lower. Again the major problems appear to be regulations and taxes. The Western Provences, Alberta, British Columbia, and Saskatchewan complain regularly that their interests are being ignored. So, earlier this year, Alberta’s legislature approved a referendum for separation from Canada. Independence! In part the reason is that Albertans find they are financing the rest of Canada. Independence is something that Quebec attempted Canada some 30 years ago. There the “exit” vote lost by a mere 0.6%, and the argument to stay was mostly economic: Quebec needed Canada’s money. Alberta does not. It funds Quebec and every other Provence of Canada.

Trump praised Alberta’s decision to Canada’s dismay. Some Albertans want to want to join the US, a fulfillment of James Knox Polk’s vision. It may not be legal, though. Alberta judge, Shaina Leonard declared Alberta separation unconstitutional as “secession from Canada will have an impact” on native groups. Why this is different from Quebec, I don’t know. The Alberta legislature is now preparing for a referendum on whether Alberta should “commence the legal process … to hold a binding provincial referendum”. This is a referendum on whether to have a referendum.

Currently Alberta is the only Provence that puts in more to the federal government than it takes out, and the disparity is huge. The Provence of Alberta has more oil than most oil countries, more that Iraq, Kuwait, or Norway, for example. It currently produces ~4.1 million barrels of oil per day. Valued at the current world rate of $100/bbl, that’s about $150 billion per year. If you divide by 5 million Albertans, the oil revenue alone is ~$30,000 per man woman or child, or $100,000 per voter. To this you can add bountiful natural gas, other minerals, and a strong industry, and you see a lot of info e that federal Canada “redistributes” east. Because of Canada’s parliamentary system Alberta has virtually no rights. Each vote is counted equally, and almost every one in Canada believes Albertans should not keep their bonanza. The central Canadian government provides programs, it’s true, healthcare with long waits and medical-assisted suicide. They also policed face masks for truckers, taking away the truckers savings and trucks if Canada found the mandates were being ignored.

Canada’s liberal politicians blast Albertans for being racist and stingy. They spend widely and run a deficit, about 15% of tax income despite the money taken from stingy Alberta. And despite this spending, managed to put Canada into recession, the only G7 country in recession, currently. Canadians are poorer than US citizens, with lower wages, and higher home prices, and Canada looking to China as an ally. I would suggest, instead, fewer regulations and less spending as Albertans want. If Alberta leaves, the rest of Canada will be bankrupt.

Current odds are against Albertans’ separation from Canada, but Quebec almost left, and the economic argument for leaving was non existent. Quebec was taking money from the rest of Canada when the Quebec separation vote came 30 years ago, and even so non-secession won by a mere 0.6%. Economically Alberta is more than self sufficient, and culturally Alberta is so like the US that it could join us easily, or relatively so. A vote for separation, if it were allowed to take place, could easily result in separation.

Cruise the Great Lakes or the St Lawrence

Leave a reply
Pearl of the Seas, one of several Great Lakes cruise companies.

The Great Lakes system presents a growing summer cruise opportunity, relatively untraveled, but so far relatively expensive. There’s great scenery, including Niagara Falls, Mackinac, Painted Rocks, Chicago, and the Soo Locks: interesting sites, and the options are growing. As a cheaper alternative, as interesting, IMHO, is the lower Saint Lawrence seaway, including Quebec City, Montreal, Portland and Prince Edward Island, leaving from Boston, NYC, or Philadelphia.

The 2026 Great Lakes season includes seven cruise lanes and 10 largish ships and 7 cruise lines, up from six lines and eight ships in 2025. Major lines include Viking, Pearl Seas, Ponant, and American Cruise Lines who provide over 800 port visits in 2026, up from 700 in 2025. The largest of the Great Lakes ships are smaller than those for Alaska and the Caribbean cruises, but more luxurious. On the St Lawrence, the ships are bigger, the prices lower, and you get more or less what you’d expect on an Alaska cruise, with an open bar, typically.

Viking Oceanis

The cost differences are more than I would expect, but coming down, I expect. Currently, a nine-day Great Lakes cruise from a Viking Oceanis cruise from Cleveland costs a minimum of $8,675 per person. The 14-day version in the map above costs $14,270+. Details: https://l.cleveland.com/g2f86w. By comparison, a Boston to Quebec City cruise costs about $1200 per person, similar to a one week European or Alaska tour, on average.

I put the blame for the high cost of Great Lakes cruising on the size limits of the locks on the St Lawrence canal and on the Niagara Falls, Welland Canal: 740 feet (225.5 m) in length, 78 feet (23.8 m) in width (beam), and 26.5 feet (8.08 m) of depth (draft). The largest cruise ship now operating on the Great Lakes, the Viking Oceanis, show above measures 665 feet (205 meters) length, by 77 feet (23.5 meters) width, by 19 feet, 8″ draft, barely smaller than the canal. It boasts a capacity for 378 guests and 256 crew members. By contrast, the Norwegian Jewel, a popular ship for the New York and Boston to Quebec City route holds 2,870 passenger and a crew of about 1,069. This explains some of the price difference but not all. The rest, perhaps is competition. A standard European cruise ship can be rerouted to the St. Lawrence, but not to the Great Lakes.

If one wanted to run a large cruise ship on the Great Lakes, it would have to be built there. It could be done, but isn’t currently. We make very large ore carriers that operate entirely on the Great Lakes, so the capacity exists. The other alternative would be to expand one of the canals. IF this were done, there would be a lot more competition and ships, and we could be served by much larger container ships as well. An unfortunate aspect of the small lock size of the Welland and upper St. Lawrence is that currently, only very small container ships can enter or leave the Great Lakes. The result is that cargo prices are much higher than for any of the US coastal ports or the Mississippi. Both the US and Canada would benefit from a larger connection to the sea.

Our new helium leak detector at REB Research

Our helium leak detector being calibrated with a standardized He leak

We just got a new helium leak detector, a Varian 938, about 15 years old, shown at right. Our old detector, a Veeco, had not worked well for years, and then we could no longer get it fixed. For a while we outsourced our leak checking, and on rush jobs it didn’t always get done. Now we can check everything in-house at much better sensitivity than before.

It used to be that helium leak checking services were common locally, in Detroit, but we lost a lot of manufacturing and our quality checkers left too, for Ohio, then abroad. Companies that used to do He leak checking switched to fluorescent die checking, which isn’t as good, and then stopped checking altogether. But small cracks at welds are not uncommon, particularly with laser welding of stainless steel. They form as the metal cools, and are too small to see. They show up in helium leakage through the micro-cracks, and if not detected and corrected, these cracks will grow and destroy a pipe or system over time. For my products, hydrogen purifiers, the micro cracks affect hydrogen purity. Any crack that helium can get through will allow impurities to diffuse into our output hydrogen. Because of the problems of micro-leaks and durability, it used to be obligatory in the nuclear navy to helium leak check every part.

The picture above was taken while calibrating our new helium leak detector. I’d bought some calibrated sources, in this case, one certified to bleed at 3.6×10-8 cc/sec, which is equivalent to 2.1 x 10-9 slpm. If a leak of that rate would appear in one of my 1 slpm purifiers, that would imply a delivered hydrogen purity of 99.999998%, and that’s generally the purity limit I certify. This is also a common leak standard in the industry, but my new detector is better than that standard. We can test down to 0.5×10-9cc/s . A 1 slpm purifier with that leak rate will deliver hydrogen at 99.9999999+ purity, more than nine-nines, as they say. On the calibration day, above, I tested three new purifiers, and found they were all perfect to the higher standard, ≤ 0.5×10-9cc/s. I’m so happy with this, I thinking of going into free-lance, helium leak checking. There’s no one local who does it.

In case you want to know, I bought this detector on eBay but found it didn’t work. I tried cleaning key parts, replaced the pump oil, nothing helped. Then bought another leak detector, with a spare filament, but without a pump or a mass-spec unit. It included the standard leaks that I now use to calibrate. That one didn’t work in the same way that the original one didn’t; we never reached pressure, and the filament never came on. Eventually, I came to believe that the vacuum pump was a fault. I sent it to a great pump repair shop in Greentown, PA, and discovered they also repair helium leak detectors. I hope to visit them. They replaced the pump and spiffed up my detector at a decent prices ($1500 as I recall). Now, it works like a charm.
