PV-assisted heat pump prototype with dual condenser reaches 7.59 coefficient of performance Researchers in Spain have developed a dual-condenser air-to-water heat pump that shifts domestic hot water production to daylight hours, maximizing PV self-consumption. The prototype boosted solar energy use from 9.9% to 55.5% and achieved a peak coefficient of performance of 7.59 under PV-assisted operation.

Women Leaders of the Net Zero Transition - YouTube To mark International Women's Day 2023, we've created a playlist featuring all of the extraordinary women leaders who've joined Michael on Cleaning Up so far.

Happy #IWD! This week @cleaninguppod.bsky.social released two episodes featuring women leaders: I spoke with Hilde Tonne, chair of Arup, and Bryony Worthington and I discussed Iran. Here is a playlist with over 50 incredible women climate and energy leaders:

I can't see the post. It's from someone I blocked, which I only do when people are persistent, aggressive, wrong and above all dull.

NEW ANALYSIS: UK emissions fell 2.4% in 2025 as coal fell to a 400-year low. Incredibly, we used less coal last year than than in 1600, when Queen Elizabeth I was on the throne and Shakespeare was writing Hamlet.

Goodbye Danny.

Goodbye Danny.

Badly wrong. Learn, then post - not the other way round.

You can't use a coffee machine to send emails. Get over it. If you want different environmental outcomes, fix real world regulations. Don't let businesses run riot and then point at the poor bastard managing your pension and say it's their fault.

A thing that won't work will make capitalism work. Got it.

Capitals Approach – Capitals Coalition A capitals approach enables organizations to understand how their success is underpinned by natural, social and human capital.

Bollox, I'm afraid. If you can't spend it, it's not wealth, it's "wealth". We can use different metrics to judge our economies and politicians, and I'm a big fan of the multiple capitals approach - but you can't pretend you can spend natural capital like cash. capitalscoalition.org/capitals-app...

Irrelevant. No project can teach FID without a bankable offtake. If they secure enough subsidies layered on top of each other, they will go ahead, otherwise they won't. This might marginally speed up the projects that get subsidies, but if it doesn't make more € tens of billions available, so what.

Thanks Bryan!

Thoughts from a three-day immersion trip to Ottawa I've just got back to London from a whirlwind few days in Ottawa, as guest of the Canadian Climate Institute. A few thoughts.

Yup. I hear you.

I hate the idea. You end up with committees and commissars deciding whether an avocado is a luxury or food, how many square feet you are allowed per child and whether you are ever allowed to fly on holiday. Environmental communism, no thanks.

Thanks. But sadly I have no special insight into the cost of tidal and floating offshore wind, and the extent they are driven by risk premiums.

As Michael points out this outcome was 100% predictable. Six months before this trial launched I interviewed a dozen EU cities who had trialled hydrogen transport. None would recommend it. All Aberdeen had to do was ask. Deeply frustrating waste of time and money.
