Well, when it comes to propane and propane axcessories . . .
I've been known to have an accessory or two.
Actually, one year in the lab I analyzed and certified all of the propane exported from the USA.
Single handedly.
No place else but Texas.
More recently I have seen some renewable propane produced in laboratory quantities but it's still going to take some time and good fortune for it to be available at the kind of scale where it can be economically purified like they do at regular oil companies, so people can fill up their barbecue tanks.
Now that was in Louisiana where they've got lots of gas too.
Propane market is a good analogy for solar and wind energy; lots of it, but hard to stockpile, and matching the producers to the consumers seems a very inefficient market with lots of economic and energy losses.
I respectfully disagree. Propane (and natgas for that matter) while harder to store than coal or crude, is a hell of a lot easier to store than electricity from wind/solar. Propane tanks can be picked up, carried and used regardless of whether the sun shines or the wind blows, hence why renewables are "intermittent" and gas-fired electricity is not.
Adding on, propane is pretty easy to stockpile as a consumer. Here's my anecdote:
I've got two 250 gallon propane tanks in my yard. One goes to my whole house generator which can go several days if needed; the other goes to the stove, water heater, and fireplace; this lasts several months, but not a whole year. After a few years experience, the best plan seems to be fill in september/october and again when prices come down in the spring. I'd probably try to get a bigger tank or a second tank for the house if we ever need to do meaningful work on the system, so we can fill once a year in the summer. Combining the two tanks I have now would probably be too expensive, and a dedicated supply for the generator seems good operationaly. The previous owner leased the tanks, and we kept going with that; it's probably better to own them as then you can get better fuel pricing.
Yes, I've got grid electricity, at least 360 days a year.
I do have and use heat pumps for heating the house; the fireplace is mostly decorative (it is properly setup to be effective at heating the room it's in, but it needs electricity to function and my generator can run the heat pumps, but maybe if the generator fuel got low). That's not going to replace my stove though. Maybe the water heater. (Oh and the clothes dryer, forgot about that one... but I've not seen good things about heat pump clothes dryers)
Another critical difference: we can store propane inside of steel and/or concrete containers. There are a few "steel and concrete" containers that can hold electricity (ex: Pumped Hydro), but the bulk of our technology is in Li-ion / rarer metals.
Steel and Concrete are two of the cheapest materials we have. Anything that uses it (rather than more expensive stuff) is strictly an advantage.
I could imagine a future where we use heat pumps with propane/rDME backup for power outages or extreme cold weather events, assuming that it won't be profitable to maintain residential natural gas for infrequent use.
Ehhh, I'm actually kind of bearish on grains as bio-fuel.
I'd like to see the switchgrass biofuel take off. A surprising amount of emissions in the USA (and Brazil) are due to deforestation associated with turning forests into farmland. That's largely mitigated by using "natural plants", like switchgrass instead of farm crops.
I mean, its all "solar power into fuel", which is great. But its also important to recognize that some (ie: switchgrass based biofuel) are better than others (ex: grain or corn based biofuel).
Give it time. ESS is making huge iron-based flow batteries that fit in a 40 foot shipping container[1], have a 25 year operating life, and can be stacked up at a solar/wind site like lego blocks to turn the intermittent generation into steady supply. There's other stuff like this in development.
That website doesn't mention cost, but just the shipping container that houses the battery is going to cost much more than an equivalent propane tank.
The battery is quoted at 400kwh, which is 1,440 MJ of energy. That is equivalent to 30KG of propane. Three little tanks like this[1] has the same energy as your massive battery.
I think these batteries would be used on the site of infra-scale renewables generation, a one-time installation, not something you'd store at your home. And there are already shipping container batteries that store 1MHW for $775k[1].
The point is that batteries are many orders of magnitude off in terms of cost, weight, size compared to fossil fuel storage.
> Electricity will be like propane, soon.
Is not true for any reasonable definition of "soon". Our efforts would be better spent optimizing the grid for variable load rather than trying to solve storage. Actual grid scale storage will be unsolvable for decades.
> It's pretty common in rural areas to have buried propane tanks that are refilled by trucks.
Prince Edward Island is rural and has no natural gas infrastructure. It’s either fuel oil (diesel without road taxes applied) or propane for fossil fuel-based heating.
Residential propane tanks are above-ground barrels that are ~5 feet tall on concrete pads with trucks coming so often.
Many of the remote rural folks end up getting propane stoves in order to be able to cook when power is out.
I live in a tiny house in NY and my water/heat/stove is propane. Get it filled by a service that I pay in advance to lock in a price for a year and save. Two big tanks sitting outside on a pad. The poor truck driver has to climb down a hill with the hose since my driveway can't handle his truck, but it's manageable.
Most water heaters and furnaces don't have replaceable jets. In theory you are correct, but in practice you buy for the fuel you have. Stoves and dryers generally have replaceable jets. I don't know why this is, just that it is.
There are lots of ultra-specific news publications that require subscriptions. It's usually not very cheap either, but if they can gather 100 annual subscriptions at $2000 a piece it's enough to pay for the salary of at least one full-time journalist and one full-time editor, as well as any design overhead. It also allows them to maintain full independence.
People who usually subscribe to these things are researchers, industry-related businesses, other journalists or traders looking for an edge. The journalists writing the content are also researchers that have a direct, exclusive interest in the content so it turns out fairly high quality. Here[0] is another in a related industry: the Iraqi oil markets. With an annual subscription cost of $2301.
In the grocery retail business, the trade press is free if you work for a retailer, and very expensive as a wholesaler. The subscription also comes with listing in a registry, moving the expense to the marketing budget.
