Electric vehicle chargers installed in the UK after the end of 2027, along with heat pumps and grid-connected domestic storage batteries, will have to be remotely controllable by power companies. This is according to the UK government’s response to its 2024 public consultation on ‘energy smart appliances’ (ESAs), which has just been published. “The government will, subject to Parliamentary approval, ...

Forget exploiting carbon nanotubes electrochemically, and just wind them up like clockwork if you want to store energy. This is not quite the message that researchers at the University of Maryland Baltimore County are delivering, but it might as well be as a team from there is storing 2.1MJ/kg in twisted carbon nanotubes – more, weight-for-weight, than Li-ion chemistry can ...

E-peas has created a power IC that can mediate between two energy harvesters, a 5V charger, a power store and a load. AEM13920 can work from any combination of two sources including: photo-voltaic cells, thermo-electric generators, RF energy harvesters or kinetic pulsed sources. “For instance, a remote control could have separate PV cells on its front and rear, to maintain ...

CorPower Ocean has resumed the deployment of its commercial-scale C4 wave energy generator, following repairs at Portugal’s Aguçadoura offshore wave energy test site. Earlier this year, CorPower found cable damage at the site, recovered the cable using remotely-operated vehicles and construction vessels, and refurbished the link. “With the site infrastructure restored, CorPower Ocean has resumed the deployment programme by testing ...

Cambridgeshire distributor Anglia Components has achieved Carbon Neutral Scheme accreditation, in partnership with ClimatePartner, by offsetting carbon emissions due to its business operations and committing to further emission reductions. This is on top of maintaining an ISO 14001 compliant environmental management system. “When customers started to ask us about carbon offsetting, we took the decision that this was a concept ...

The first anchor has been installed for CorPower’s 9m diameter 300kW C4 wave power converter. The custom anchor, dubbed Umack, has been installed 4km off the coast of northern Portugal at Aguçadoura, where the giant buoy will be part of the HiWave-5 wave power demonstration project. C4 generates power by bobbing up and down along the axis of its single ...

CorPower Ocean has revealed the first 9m diameter hull for its 300kW C4 wave energy converter. The hull was built composite machinery specialist Autonational and composite tank specialist  CPT Tankwell, in Portugal using a custom-built machine in an environmentally controlled work cell. Yes, it is that big “The C4 hull has been designed with a low-cost sandwich structure comprising of ...

CERN and ABB are to study electric motor energy use at CERN, and will publish the results for public use. ABB described the project as “non-commercial” and said that it will demonstrate how data insight and service expertise can be applied to make better decisions about saving energy and increasing reliability at large-scale research facilities. “Currently, motors used to power ...

Lithium-carbon dioxide batteries have theoretical promise, including in aviation where the lightweight materials are desirable – it might might make good use of Mars’ 96% CO2 atmosphere, for example. Headline figures are a theoretical specific energy density of 1,876Wh/kg and a ~2.8V discharge potential, but in practical terms the technology has not even reached infancy. To build a solid foundation for its development, a ...

Georgia Tech’s SlothBot concept has been turned into a demonstrator, that will hang around in the canopy of Atlanta Botanical Garden monitoring temperature, weather, and carbon dioxide levels. The concept was modelled on real sloths – animals that hang from branches and move slowly to conserve energy. “SlothBot embraces slowness as a design principle,” said GaTech engineer Profesor Magnus Egerstedt. “That’s ...
