jmInfluential energy analyst Michael Liebreich and University of Cambridge mechanical engineering professor David Cebon drew attention to the now-37 independent studies showing that hydrogen boilers would require about five times more renewable energy than heat pumps — likely making them significantly more expensive to run.
“This trial is entirely pointless in terms of proving whether hydrogen is the most cost-effective way of decarbonising homes,” Liebreich told the audience. “Every single systems analysis from every single expert who is not paid for by the gas industry or the heating industry has concluded that hydrogen plays little or no role.
“The thing that it’s intended to do, though, is maintain the debate and discussion and the delay [of decarbonisation]. If you’re running a gas network organisation, as our next speaker [Cadent head of strategy, Angela Needle] does, what you really want is to continue to harvest profits off that. If you invest today in a gas distribution network, you get to charge 6% per year for 45 years on that investment and that’s until 2068.”

This custom component will add crucial features to your climate-controlling TRV (Thermostatic Radiator Valves) to save you the work of creating automations to make it smart. It combines a room-temperature sensor, window/door sensors, weather forecasts, or an ambient temperature probe to decide when it should call for heat and automatically calibrate your TRVs to fix the imprecise measurements taken in the radiator’s vicinity.
So basically if you have smart TRVs and a room temperature sensor, you can drive that as a pair.]]>thermostat smart-home home-assistant heating trvshttps://pinboard.in/https://pinboard.in/u:jm/b:e935d73844c5/Experiments with Far Infrared Heating2022-08-10T17:21:34+00:00
