why are we so hellbent on battery power for cars, seems so costly on an environmental scale (mining, disposal of batteries, charging) when hydrogen is hundreds fold times more energy dense and millions of times more abundant and cleaner.
danger of hydrogen? difficult to extract?
Energy Density of some Combustibles (in MJ/kg)
- the cynic in me will say it's available to all so no nations or handful of corporations can control the supply_niko
- it seems like everything I read about the cons of hydrogen sounds like paid research from the oil lobby._niko
- I know nothing about this subject at all. However after looking at this one graph i think i'm able to offer the valuable opinion that the science/engineering...Morning_star
- ...isn't advanced enough to provide an economical alternative that maximises both efficiency, cleanliness of the fuel and impactless disposability.Morning_star
- Thank Elonutopian
- could be morning star, but looks like Hyundai is making a big push for it https://tinyurl.com/…_niko
- India is big on developing that kind of clean energy: https://bit.ly/3Al9c…uan
- Godspeed to them! Hopefully they succeed before Saudis with truckloads of bribe money, Israeli assassins or American hostile takeovers shut it down_niko
- batteries just the next environmental disaster waiting to happen. hydrogen will replace mains gas supplies in most of europe by 2050kingsteven
- Yeah no:
https://www.quora.co…******** - Storage density and material embrittlement are the two main problems of pure hydrogen. Ammonia's an interesting medium route for hydrogen as storage.Nairn
- it will be impossible to refit most other options (heat pumps, district heating etc.) in to existing homes. i've been looking in to it myself (house is 1950)kingsteven
- Whilst Hydrogen has a very high energy density per mole, squishing it so that "a tank's worth equivalent to petrol" is .. tricky.Nairn
- a lot of the mains infrastructure has been replaced with poly pipes, hybrid boilers will be developed so it can be phased in.kingsteven
- will be interesting anyway, i don't think the levels required for residential heating are unsafe but i could be wrong + not sure about cars hakingsteven
- They're trialling a 20% hydrogen mix in the standard gas supply somewhere here in England - doesn't require a change in [mdoern] infrastructure apparentlyNairn
- Apparently ye olde coal gas was mostly, or at least signifcantly, hydrogen. All this has happened before, and will happen again...Nairn
- why aren't doritos on this list?Gnash
- a close friend of mine, a physicist, works in energy industry. Has ranted on several occasions about the pros and cons of Hydrogen. Mostly cons.inteliboy
- The oil industry love hydrogen as it keeps them in control. It requires huge amount of pressure to contain. You need a ton of energy to make hydrogen fuel. etcinteliboy
- Fusion + Hydrogen, problem solved.
And if it doesn't work... Kaabooommm!! (The earth)OBBTKN - Batteries is the only way to benefit from renewable energy (hydropower, wind power etc). In Norway hydropower is 98% of all electricitydrgs
- You woul need to fill a room with home batteries to heat or cool a mid-century house, hard to see that tech progressing to meet the need by 2050kingsteven
- As gas runs out, prices increase and folks move to electricity to heat their homes and run cars you need over 20x the renewable infrastructure to meet demandkingsteven
- batteries and that rely on mining massive quantities of lithium, solar - neodymium and cobalt reliance on china, wasteful disposal or just use hydrogen?kingsteven
