Four good news climate stories from 2023

Including a positive way to think about tipping points.

#DYK that an #ElectricArcFurnace can use up to 100% scrap steel as its raw material? ๐Ÿ—โ™ป Traditional #steelmaking using a blast furnace emits around 2.32 tonnes of CO2 per tonne of steel produced. Switching to an electric arc furnace could reduce that number to 0.67 tonnes of CO2 per tonne of steel.

A great article by Dr Rebecca Waldram summarises what you need to know about electric arc furnaces and why the UK needs to #decarbonise its steel industry.

Electric arc furnaces: the technology poised to make British steelmaking more sustainable

Electric arc furnaces can use up to 100% scrap steel as its raw material, resulting in a significant reduction in emissions.

At this early stage of development, it is vital that #Perovskite #SolarCells are designed for a #CircularEconomy to ensure #sustainability.

This was emphasised in a recent paper in the Royal Society of Chemistry Energy and Environmental Science journal.

Why Perovskite Solar Cells Must be Designed for a Circular Economy

Perovskite solar cells must be designed for a circular economy from the get-go. A new paper stresses the importance of ensuring sustainability and reducing waste.

@EarthOrgUK This is not widely adopted, but should be the default control method type (whether from Homely or a competitor) for all heat pumps in my opinion.
@EarthOrgUK I'd be interested to see a new metric like a "cost performance factor" based on the end user cost per kWh delivered.
This is where smart controls like https://www.homelyenergy.com/ come in.
This controller will blend weather comp with TOU pricing strategies, actual weather (driving wind, rain, solar gain in winter), and controls the heat pump via modulation, not a switch.

@EarthOrgUK Lower flow temp, higher COP.
Also, overall sCOP includes the hot water COP and is usually lower as the hot water heating performance is lower (because it's pushing to a higher temp), BUT what is not accounted for in sCOP measurement or tracking is the overall cost per unit of heat delivered, when factoring in access to TOU tariffs. If you can charge hot water overnight at 1/3 price electricity, then DHW COP is less important, as is the space heating delivered during this window

@EarthOrgUK

The aim in setting up the control strategy for the home, is to meet heat loss at a specific outside temperature. The performance curve ramp should therefore be set on the assumed ideal to modulate effectively for the local climate.

Reality is that secondary thermostats and smart TRVs are still fitted in many instances where this system is misunderstood, and can interfere with the efficiency of a well-designed system, by causing unnecessary cycling. Less cycling, more efficiency.

@EarthOrgUK

Sorry for the delayed response! Hopefully some useful info here (from one of our team members):

The Heat Pump Wave: Opportunities and Challenges https://publications.jrc.ec.europa.eu/repository/bitstream/JRC134045/JRC134045_01.pdf

Reference to page 73:Rated capacity vs performance curves.
Heat pumps should have option to set performance curves, which are essentially weather compensation of flow temperature (or at least power to meet set flow temp), which needs to be set to optimum at point of install (or shortly thereafter once optimised)

The Royal Society of Chemistry and Chemistry World are holding a webinar to explore how scientists can engage with the public via the media. Alice Motion and David Hu will discuss the diverse spectrum of media engagement, the power of media to bring about positive change in science and tips for successful interactions with the media.
