The idea is pretty simple: use focused solar energy to heat water (or other carrier: I've heard liquid sodium is ideal) to make super-heated steam to power turbines. At night just use a gas burner or excess heat from a cement kiln or whatever.  The big solar arrays I've heard about have a problem with too much heat. They have to de-focus the mirrors to keep from burning up the piping.

A big problem is birds, though. As you get closer to the 'furnace', the solar rays get more focused, i.e. hotter. Apparently it'll vaporize anything that gets too close. Your Thanksgiving turkey is ready in three seconds flat though.

i'm not sure how significant this is, and it's an incremental improvement, not a new technology as the article acknowledges. The cement industry thing is a bit misleading. Yes it uses a lot of heat to make, but a lot of the CO2 release is from turning the limestone CaCO3 into lime CaO and you can't get around that

Amazing development. If you applied this technology to heating living/working spaces as SFW suggests, I think you'd have to work with large apartment/office buildings.

This is also cool:

Heliogen said it is generating so much heat that its technology could eventually be used to create clean hydrogen at scale.
That carbon-free hydrogen could then be turned into a
fuel for trucks and airplanes."If you can make hydrogen that's green, that's a gamechanger," said Gross. "Long term, we want to be the green hydrogen company."
 
It will be interesting to see if the industries this technology is tailored to, cement, steel etc. will invest in the change over from fossil fuels. Or is it just easier for them to keep what they have in place, continue to use fossil fuels and still make boat loads of money. Its a positive step to develop the tech though. Not holding my breath it will be the new standard.

sulfur battery tech?

How Inexpensive Must Energy Storage Be for Utilities to Switch to 100 Percent Renewables?

MIT researchers list the energy storage technologies that could enable a 100 percent renewable grid


Another viable technology is flow batteries that would use abundant, low-cost chemicals to store energy in large tanks. But not all flow battery chemistries are inexpensive. One of the main types, vanadium redox flow batteries, have an estimated cost of $100/kWh, the researchers say, but more development could bring down costs.

Chiang is betting on sulfur batteries. He has recently developed an aqueous sulfur flow battery that could cost as little as $10/kWh. The technology has what it takes for long-duration, low-cost storage, and is now being developed by Form Energy, a company he co-founded in 2017 and that has recently gotten extensive financial backing.

There are other battery technologies to keep an eye on. High-temperature sodium-sulfur batteries cost $500/kWh, but with more development, their costs could fall by up to 75 percent by 2030, according to the International Renewable Energy Agency. Meanwhile, the cost of sodium nickel chloride batteries could fall from $315 to $490/kWh at present to $130 to $200/kWh by 2030.
