Is water the solution for renewable energy storage?

Sustainability Matters

February 26, 2020

Seasonal pumped hydropower storage means pumping water into a deep storage reservoir, built parallel to a major river, during times of high water flow or low energy demand. When water is scarce or energy demand increases, stored water is then released from the reservoir to generate electricity. IIASA research published in the journal Nature Communications showed that compared with other mature storage

Five ways UK energy managers can help deliver a net-zero economy

Ethical Corporation

February 25, 2020

Despite being a major overhead, most businesses still don’t fully understand exactly how, when or where they use energy, or know how much it’s going to cost in five years’ time. The energy landscape is also changing rapidly: as energy managers know well, new regulations, supply security and sustainability demands present new challenges.Image: Channels: Business

UQ develops quantum dot solar cells

Sustainability Matters

February 18, 2020

A University of Queensland (UQ) team has developed quantum dot solar cells that can be made into thin, flexible films and used to generate electricity. The technology converts solar energy to electricity via the use of tiny nanoparticles called ‘quantum dots’, which pass electrons between one another and generate electrical current when exposed to solar energy in a solar cell device. The

Powering electronics with waste heat

Sustainability Matters

February 16, 2020

Thermocells are devices that convert environmental heat, such as that lost from the human body, into electricity via a thermal charging effect. Although inexpensive and efficient, thermocells have historically produced temperature-dependent low output voltages — just tens of millivolts (mV). Researchers from the University of Tsukuba in Japan have now improved the energy-harvesting
