Using hydrogen for low/medium temperature industrial process heat is by far the most expensive option available.
Our recent analysis shows that heat pumps coupled with electro-thermal storage is the most cost-effective technology.

During 2005 deployment to Samarra, Iraq, Hegseth was part of a company where Four soldiers from that company were later court-martialed, with three convicted of killing unarmed Iraqis.

Heat pumps are the most efficiency heating technology ever invented.
That's because they harvest, compress and transport pre-existing heat from the air, the ground or the water.
Compared to a gas boiler heat pumps deliver ~4x more heat for each unit of energy inout.

So Pakistan is *paying* Qatar to *not* deliver LNG because even including this penalty payment their solar PV and battery spending is much better value for money and saves them billions.

Bill Gates hasn’t made sense on Climate since he teamed up with Bjorn Lomberg in 2009. This is just a restating of Bjorn’s book from this year about how we have a finite amount of money and we shouldn’t use it for climate. What they get wrong is that climate solutions are now fully profitable.
Bill Gates has a new memo out calling for a “strategic pivot” on climate change, downplaying “doomsday” talk to focus on filling enormous post-USAID budget gaps in global health and vaccine funding. I got an early glimpse of his thinking last week:

Exactly
Renewables are a masterclass in learning-by-doing. Each doubling of deployment cuts costs via experience curves: better manufacturing, finance & supply chains.
Result:
Solar now cheapest new power in many regions
Falling battery costs enable flexibility
Electrification gets more attractive
