Jan Rosenow (janrosenow@mastodon.energy)'s status on Sunday, 08-Dec-2024 21:21:37 JST Jan Rosenow The battle for the biggest heat pump:
Finland currently builds the world’s largest air source heat pump with a capacity of 33 MW - about 4,000x bigger in capacity terms than an average domestic heat pump.

Jan Rosenow (janrosenow@mastodon.energy)'s status on Sunday, 08-Dec-2024 18:14:34 JST Jan Rosenow A remarkable transition:
Kenya is Africa's leading country when it comes to renewables.
In 2000 fossil fuels contributed 60% to electricity generation.
Today it is 6%. In 2023 electricity was from almost 50% geothermal, 20% wind+solar and 22% hydro.

Jan Rosenow (janrosenow@mastodon.energy)'s status on Monday, 18-Nov-2024 07:07:23 JST Jan Rosenow Heat pumps are the most efficient heating technology ever invented.
They provide 4x more heat for the same energy input.
That’s because they use the energy input to compress and transport pre-existing renewable heat rather than burn a fossil fuel.

Jan Rosenow (janrosenow@mastodon.energy)'s status on Saturday, 16-Nov-2024 23:13:49 JST Jan Rosenow Cold climate heat pumps have arrived.
Even down to -25C some models still deliver heat with an efficiency superior to fossil fuel heating systems.

Jan Rosenow (janrosenow@mastodon.energy)'s status on Tuesday, 12-Nov-2024 12:34:13 JST Jan Rosenow Crazy fact:
Even if you just installed a new gas boiler ripping it out and replacing it with a heat pump makes sense from a carbon perspective.
Carbon emissions associated with manufacturing the boiler and the heat pump are offset in less than 2 years.
After that the heat pump will save carbon year on year.

Jan Rosenow (janrosenow@mastodon.energy)'s status on Monday, 11-Nov-2024 01:25:54 JST Jan Rosenow Most people don’t know this.
Heat pumps REDUCE gas consumption even if running 100% on electricity from a gas fired power plant.

Jan Rosenow (janrosenow@mastodon.energy)'s status on Friday, 08-Nov-2024 18:14:45 JST Jan Rosenow Already today with the current electricity mix in the UK heat pumps reduce fossil fuel consumption 4x compared to gas boilers.

Jan Rosenow (janrosenow@mastodon.energy)'s status on Saturday, 02-Nov-2024 22:36:32 JST Jan Rosenow No we don’t have to replace all fossil primary energy.
We only have to replace the useful energy with clean energy using much more efficient technologies.
We don’t need to replace the wasted fossil energy. We can avoid the inefficiency in the first place.

Jan Rosenow (janrosenow@mastodon.energy)'s status on Saturday, 02-Nov-2024 22:36:26 JST Jan Rosenow BloombergNEF and Energy Transitions Commission anticipate that more sectors will decarbonise via electrification rather than hydrogen.
That’s because electrification costs are falling faster and hydrogen costs are not dropping as expected previously.

Jan Rosenow (janrosenow@mastodon.energy)'s status on Saturday, 02-Nov-2024 22:35:35 JST Jan Rosenow The world's grid-scale battery storage capacity grew by 120.8% from 2022 to 2023, which puts us on track to reach the International Energy Agency (IEA)’s target of 1300 GW of battery storage by 2030.
China now has nearly half the world's battery storage capacity, growing 249.1% from 2022-2023. The U.S. comes in second place with 28.3% of the world's capacity, which grew by 70% from the previous year.

Jan Rosenow (janrosenow@mastodon.energy)'s status on Friday, 25-Oct-2024 23:37:23 JST Jan Rosenow Cold-climate heat pumps are coming.
8 manufacturers that took part in DOE Residential Cold Climate Heat Pump Challenge now take new products to market.
These heat pumps reliably delivered heat even during coldest winter months, with some units operating down to -26C still meeting energy efficiency requirements.

Jan Rosenow (janrosenow@mastodon.energy)'s status on Friday, 18-Oct-2024 19:16:55 JST Jan Rosenow HOT OFF THE PRESS: Grids, grids, grids – how ready are European power networks for the energy transition?
GLOBSEC releases its first grids transition index.
Of course any index is subjective and incomplete but hopefully this analysis will stimulate productive discussions to resolve the challenges we face.
For full disclosure: I’m on GLOBSEC’s Energy Advisory Committee but have not been part of the team writing the report.
Full report here: https://www.globsec.org/what-we-do/publications/globsec-grid-transition-index-2024

Jan Rosenow (janrosenow@mastodon.energy)'s status on Thursday, 10-Oct-2024 01:22:52 JST Jan Rosenow The EU's grid just keeps getting greener and greener.
The grid is now significantly cleaner than a decade ago.

Jan Rosenow (janrosenow@mastodon.energy)'s status on Wednesday, 02-Oct-2024 00:44:54 JST Jan Rosenow It’s done.
This is the moment Britains last remaining coal power station came off the electricity system for the final time, marking the end of 142 years of coal generating electricity in Great Britain.

Jan Rosenow (janrosenow@mastodon.energy)'s status on Wednesday, 25-Sep-2024 20:30:06 JST Jan Rosenow Fun fact: There are >10,000x more public EV chargers in the UK than hydrogen refuelling stations.
Only 6 hydrogen refuelling stations remain with almost 70,000 public EV chargers covering the country.

Jan Rosenow (janrosenow@mastodon.energy)'s status on Tuesday, 24-Sep-2024 22:22:14 JST Jan Rosenow Most of the energy debate is focused on the tip of the iceberg - electricity.
But almost 80% of our energy use is for heat and transport relying heavily on fossil fuels.
Decarbonisation requires an all-sector approach.

Not that long ago coal provided 40% of UK electricity.
