Oooh is it a FT conspiracy going on here?

Why? Their energy reporting is excellent.

Electro-thermal storage systems (ETES) are one of many technologies to electrify industrial heat.

This week I moderated Thermal Energy Day in Budapest. The event brought together leading voices to discuss infrastructure, markets & thermal storage.

China ≠ just coal plants and solar exports. The deeper shift: electrifying everything it can. Strategic, because China relies on imported fossil fuels. Coal is still king in the power mix—for now. But the balance is changing year by year.

I clearly stated it in the paper: public research grants for the vast majority of them and foundation grants.

In Hungary today: Kyoto Group inaugurated one of world’s largest thermal energy storage units at KALL Ingredients. 56 MWh Heatcube → >30 GWh clean heat/yr, up to 8,000 tCO₂ cut/yr. Flexible, renewables-powered, 14 MW steam. Heat-as-a-Service model makes it scale.

What temperature range?

This is a project that will reduce gas consumption.

Two graphs in today’s FT.

Notice the UK’s position on both graphs.

Heat storage is finally getting the attention it deserves in the net-zero transition!l

Today I moderate Thermal Energy Day in Budapest. This event brings together leading voices to discuss infrastructure, markets, and thermal storage.

Despite the noise, renewables keep rising now generating more electricity than coal.

@iea.org halved its US outlook, but raised India’s by 10%, putting it on track as the No. 2 growth market after China. MENA up 23%, driven by Saudi wind and solar.

BASF builds one of world’s largest industrial heat pumps. I told Chemistry World:

“BASF is the largest chemical company in the world. Putting its weight behind heat pumps at this scale signals confidence in the technology in the chemicals sector and beyond.”

Yes heat pumps do work in old buildings. @trinityoxford.bsky.social founded in 1555 got a ground source heat pump fitted by Rendesco in 2024 when the photo with the drilling rig was taken.

Compare it to what it looks like today - the tourists taking photos have no idea what’s under the lawn.

As always. An anonymous keyboard warrior. Bye bye.

Who are you and which analysis have you carried out that proves your point?
janrosenow.bsky.social
Lol. That just offers opportunities for storage tech other than electric batteries such as thermal energy storage with better round trip efficiencies.

Exciting developments in solar.

Just read this fascinating FT article on perovskite solar panels – the next-gen innovation that's lighter, more flexible, and up to 20% more efficient than traditional silicon ones.

Imagine panels turning everyday surfaces into power generators
