@just-jeepin That's cool. The rust in the cab corners looks pretty bad and I was going to say that the tyres must be a million years old, but they look Russian, so maybe not. I like the big PTO winch hanging off the side of the chassis.
@hfv I think today it definitely looks of its era; a little "melty" like a lot of concept cars of that time, as carmakers were breaking out of the sharp-creased box paradigm of the 80's. But to see this from Volvo at a time when the 240 was still on showroom floors must have been a real shock.
@bison78 What if it is surplus and created off peak? Is it really diverting power that would go to the grid? It can also tap into the nearby larger Bonneville grid to produce from surplus as well. In this case the energy potential would go to waste anyway.
The dam’s 10 turbines have the ability to produce up to 840 megawatts of electricity, enough for more than 640,000 homes. But the dam can only store a small amount of water. So, for the most part, the river must be sent through the turbines, or spilled downstream in volumes limited to protect young migrating salmon from too high of concentrations of dissolved gas in the water by the dam. Wells Dam, owned by the Douglas County Public Utility District, will supply electricity to pull hydrogen gas out of well water. A fish hatchery has been built in the last two years alongside the dam.
The ability to direct electricity to hydrogen production will help to even out generation, reducing wear and tear and costly maintenance on the turbines, according to Ivory, the general manager.
Personally I don't think NG plants are going anywhere anytime soon. They are way too valuable to our grid in the near future. However we need better answers to our energy storage problem. If we are to wean off fossil fuels we need to rely on unreliable sources of power. In order to do that we need to store it when we can. Hydrogen is just one way of being able to store energy. I'm certainly not saying it's the best. I think it is viable for some areas but not all and the infrastructure should be built accordingly.
If it would go to waste anyway, then, yes, it's clean, but most hydro is an excellent energy storage and dispatchable electricity source.
Anyway, using hydrogen for transport is stupid at the moment. Any green hydrogen should be used to displace the natural gas-derived hydrogen that is used in large quantities in industry.
