Minigrids and PV are great, but local businesses like bakeries need intense heat for cooking.
Electric ovens can easily overload a grid, but Lytefire solves this by using mirrors to convert sunlight directly into heat.
This is far more efficient than 20% efficiency solar panels and keeps minigrids reliable by displacing high-energy thermal loads.

Raygen to build Concentrated Photovoltaic plant with Thermal and Energy storage.

The Yadnarie project, potentially sized at 150 MW of solar capacity, 90 MW of thermal energy capacity and 720 MWh (8-hours) of energy storage, has recently won state planning approval, and has long been expected to the first big project to be built following the success of the technology at a pilot plant at Carwarp in Victoria.

Want to work against the climate crisis and for renewable heating?!

Solar Heat Europe, which represents the solar heating industry at EU-level has two interesting vacancies.

Senior Policy Officer (full time)

Operations and Finance Manager (part time)

I worked for this association from 2002-2009 and can only recommend it. It's a small team, so you are immediately involved in various topics.

Giant French Nuclear Developer makes investment in Australian Energy.

No, Dutton, Not a nuclear plant, but the future. A 30 MW solar thermal project with eight hours of storage (240 MWh) in Port Augusta, and an accompanying solar methanol plant, in what would be the first large scale solar thermal project in the country.

Vast Renewables says it has now secured nearly half of a promised grant.

#Solar #waterheaters were cool in 1980s. They could be again.
"[T]oday, hardly anyone is using these #solarwaterheaters even as #photovoltaic panels have popped up on the roofs of nearly 4 million American homes."
Cheap photovoltaics still make economic sense for many homes (unless you're heating a pool). "But the cost of #solarthermal could look like a bargain if we consider increasingly unreliable #electricgrids and the cost to the #climate from burning #fossilfuels."

I'm not and yes I think #Lithium batteries are also no option.

Granted, there are sufficient #PowerToX technologies that work, regardless if #Hydrogen or even better handleable and much more energy-dense and storeable: #Methanol.

Also #Solarthermal power exists and it's trivial as it uses the economies of scale you get from any thermal powerplant - nuclear or fossil or geothermal.

Also all turbines and generators need those...

(Sorry I can't write in French...)
#SolarThermal has provided most of my hot water for 35 years. Lots of learning about #FreezeProtection at first - "drain back" required an unbearably noisy pump, "drain down" required tricky valves that failed often. And domestic water in the panels quickly clogged them with #HardWater minerals.

What works is a closed loop with antifreeze in the panels and a heat exchanger, heating a large storage tank. Domestic water passes through another exchanger in that big tank as it is used.

In my system a gas heater or a #WoodBoiler can also heat the big tank when there is no Sun. And the accumulated heat can be pumped through #Hydronic floors. All this was a huge expense at first, but divided by 35+ years (and current fuel prices) it is wonderful!

Anyone have any experience running solar thermal and/or heat pumps on private water supplies (i.e: low pressure)? Can it be done and is just less efficient? Did you *need* an accumulator to raise the pressure? #renewables #heatpump #solarthermal #solar #greenenergy #centralheating

Solar thermal technology can store solar energy as heat and use it to generate electricity or provide industrial heat when needed. Unlike batteries, solar thermal can store energy for longer periods and at lower costs. Solar thermal could help Australia transition to a renewable energy system and reduce its reliance on fossil fuels.

Using #hydrogen for heating may sound attractive at first glance. However, all of the independent research on this topic comes to the same conclusion: heating with hydrogen is a lot less efficient and more expensive than alternatives such as #heatPumps, #districtHeating and #solarThermal such as #PVT.

Everybody is talking about heat pumps.

May I point your attention to solar district heating.

Its not a pilot project. In Denmark they have them since at least 30 years.
