Is it less than using fossil fuels for power exclusively? If so then it’s a step in the right direction. Yes I know it sounds like I’m shilling for BP now but we get lost in the doom spiral so fast we forget we are indeed making progress. We just have to keep their feet to the fire or…erm… solar panel?
And this is still a large step in the right direction, because cheap hydrogen creates an incentive to develop hydrogen infrastructure, which increases the demand for hydrogen, and can help lay the groundwork for a future in which hydrogen is produced from renewable sources.
Also, steam reforming lends itself well to CCS, and as such it can be performed without carbon emissions.
There isn’t a real need for hydrogen. We have plenty of other solutions. People have the expectation that our society changes from unsustainable to sustainable by just swapping in clean technologies in place of the dirty one’s. That isn’t going to happen, and hydrogen won’t change that.
My roomie is a trucker, and the idea of an electric truck is laughable, at least in my country, because of how trucking works here. Unless the truck is out of order, being loaded, or being refuelled, it’s always on the road; they just swap drivers around like a relay race. Unless a truck came with a swappable battery it wouldn’t be feasible to operate like that, they’d have to at least double their arsenal, (at which point we can already start to question how environmentally friendly that is), and that’ll increase the overall operating costs, which will ultimately end up on the consumer; everything will get more expensive because that’s what they transport. Another problem with pure electric is also that the batteries weigh a shit ton, so the trucks end up being able to transport less because they have to lug the battery around everywhere.
Biogas is an alternative, and as far as I know it works alright; they already use it. They end up not as powerful as diesel trucks though.
Something I wonder if it might be applied is something like Toyota’s hybrid system, with regenerative braking etc. I wonder if it scales. My roomie recently had to leave his Golf at the shop for a week, and got it swapped with a Yaris. It cut his fuel consumption by three quarters.
The alternative to trucking is a better cargo rail system on electrified rail. Won’t get rid of all long haul trucking, but it’ll displace at least 70% of it.
Even if that doesn’t happen, battery capacity improves by 5-8% per year. At the low end, that’s a doubling every 15 years. We’re not close to theoretical limits yet, so we can expect this to continue as long as we keep funding the research.
Solid state batteries are still some time away, but once those are on the market, they’ll leapfrog everything. Good enough not just for trucking, but also airplanes, which was thought to be out of the question otherwise.
I find with a lot of workers in positions like that tend to focus on what exist right now. Then they sit around at a truck stop over coffee, reinforcing their opinions and laughing at battery trucks. They don’t think about what’s likely to happen over the next decade.
But still, trains are the way to go. The US needs to start that process by renationalizing the railroads.
I wouldn’t argue against expanded rail. Used to have a decent rail system in my country, hell even the town I currently live in, while small, actually has rail. A lot of it has been shut down however, and that’s a shame. Sweden is a pretty large country dotted with a lot of small towns. If we had rail connecting places we’d not need as many long-haul trucks, and the more local deliveries could definitely be handled by EV trucks and vans. It’s the long haul that’s an issue. As it stands though, proper investment in rail doesn’t seem to be a high priority more or less anywhere. Instead we get stupid ideas like putting up electric lines over motorways, costs just as much but is less versatile.
It’s quite sad. The rails are still here, I think they might be used by the local industry every so often, but I genuinely have no idea as I know my roomie has delivered stuff to them before and he obviously doesn’t drive a train. The old station house is also still here, just abandoned, not even repurposed for something else.
If solid state batteries actually came around then sure, EV trucks might become more viable, particularly if they can charge decently fast since fuelling a truck does take a while (like 15 minutes or so) so there is downtime. There could also be other incentives, like tax reductions (or tax increases on fossil fuel trucks) making EVs more appealing. I believe the reason you hear truckers ridicule the current tech is because there is a push for trucks to be replaced with EVs and it’s just not feasible today, unless you do short distance shuttle deliveries. You can replace your long haulers with electric trucs, Mercedes for example makes them, but as it stands the only effect would be that you’d go bankrupt.
Fallen branches, leaves, and trees not already needed for any animal habitats or nutrition. The string to hold it together is, of course, woven from your own hair.
Also, no fires, since burning wood releases carbon into the atmosphere, so warmth can only be generated by sewing together carcasses of animals who died natural deaths.
And finally, following a strict diet to minimize gastro-intestinal discomfort lest you release methane into the atmosphere.
Or just make a rope from your own hair and hang yourself with it, as that’s honestly the only way you can make no impact on the environment. I mean, don’t do this, obviously, but that’s it. As long as we exist, we affect the environment, so we should just do what we can to mitigate the negative effects. The perfect is the the enemy of the good.
“Oh, your solution doesn’t break the laws of physics? Trash it, we’re gonna keep burning shit to make more shit we can burn forever until you have a magic solution or until we kill the planet”
You
The hundred year solution is nuclear. The thousand year solution is colonizing other planets.
Ultra dense energy has its place, namely where weight and volume are critical like in aerospace. Everything else can deal with not putting more carbon and worse things in the air.
You’re taking an off-hand joke comment pretty seriously there, bud.
I’m a proponent of things like solar and nuclear, but having some kind of fantasy position of them being perfect technologies with no downsides whatsoever is a special kind of delusional.
You want to actually convince people of their benefits? Stop making up dream scenarios and provide realistic examples.
I can’t help you with any more of a real world scenario. If you want to offset some dollar amount of your energy use with home-grown juice, that’s the easiest way to get it done right now.
Solar panels lasting for decades here and now, that’s close enough for all practical purposes.
Solar has a proven track record, hydrogen technologies never made it past gospel.
Solar panels (PV) degrade over time and use and have to be replaced and disposed of. A better case would be for things like solar furnaces that are simpler, but most of the time solar implies PV panels.
Unfortunately, no. It’s not. However, there is some nuance here. Even though their approach is more polluting, it allows infrastructure down the line such as modern cars to be upgraded to use hydrogen.
The hydrogen factory can then later be replaced by a non-polluting one. Much like how a lot of places switched to electricity while the power was being generated by natural gas. Some places moved to using nuclear later, and poof, carbon neutral.
In the end a transition is easier to divvy up progress with small architecture changes, not small bits of absolute carbon emissions / pollution
bp themselves still talks about “if we can decarbonise it’s production” (it being hydrogen). They have published in more detail, but they’ve not made it as easy to find. If you do some searching you can find their approach in more detail tho.
For the rest: knowing an electric device does not care where the electricity came from. You can double check this by seeing if the same smartphone exists all over the planet.

They’re not using electrolysis and water to make hydrogen, they’re using power and steam to crack petroleum products into hydrogen.

I mean it’s not bad to have alternatives though.

For energy it is terribly inefficient.
It would be nice to have green ammonia and methanol though.
Definitely. We already saw this with fucking natural gas
Might’ve been a step forward 40 years ago. Today its finding a spot to dig in, so they can keep the fires of hell burning.
But they aren’t capturing the carbon. They aren’t storing it. It’s supposed to be the easiest case of CCS and they dump the CO2 in the atmosphere
I strongly suspect that CCS is a lie aimed to make people happier to continue burning fossil fuels
using electrolysis for fuel cells would violate the laws of physics and thermodynamics
In the spirit of the comic - how is the solar panel made?
short answer: once
Wow, solar panels that last forever? That’s quite the technological achievement…
This is the dumbest fucking argument. I’m sorry but what point do you think you’re making?
Is it imperfect? Yes. Just like ALL OTHER THINGS. Is it a major improvement compared to burning coal? OBVIOUSLY YES.
The obvious answer is to live in a yurt, drink rain water, and never use electricity again that you don’t make from a bicycle-powered generator.
What’s the yurt made of?
Fallen branches, leaves, and trees not already needed for any animal habitats or nutrition. The string to hold it together is, of course, woven from your own hair.
Also, no fires, since burning wood releases carbon into the atmosphere, so warmth can only be generated by sewing together carcasses of animals who died natural deaths.

^ this guy carbon neutrals
Its not an argument, its a joke.
You must see enemies around every corner… I’d recommend talking to a therapist about that.
I would, but they’re all out to get me.

You can buy solar panels at Costco.
I can’t help you with any more of a real world scenario. If you want to offset some dollar amount of your energy use with home-grown juice, that’s the easiest way to get it done right now.
You can build a small amount of wind power from old car parts. If you don’t have a Costco membership.

With lots of slave labour, and unimaginable damage to the environment from mining.

Not enough progress fast enough. We’re kind of on a clock here, we can’t see exactly where we are, and we might already be too late to do anything.
