Alleviating oxygen evolution from Li-excess oxide materials through theory-guided surface protection

open access: yesNature Communications, 2018
Rechargeable Li-ion batteries can show extensive oxygen loss from the cathode material under operating conditions. Here, the authors use high-throughput computational screening to guide the synthesis of a Tantalum-doped Li-excess cathode that ...

The full phase space dynamics of a magnetically levitated electromagnetic vibration harvester

open access: yesScientific Reports, 2021
We consider the motion of an electromagnetic vibrational energy harvester (EMVEH) as function of the initial position and velocity and show that this displays a classical chaotic dynamical behavior.

Maximising revenue for non-firm distributed wind generation with energy storage in an active management scheme [PDF]

open access: yes, 2013
The connection of high penetrations of renewable generation such as wind to distribution networks requires new active management techniques. Curtailing distributed generation during periods of network congestion allows for a higher penetration of ...

Underground Gravity Energy Storage: A Solution for Long-Term Energy Storage

open access: yesEnergies, 2023
Low-carbon energy transitions taking place worldwide are primarily driven by the integration of renewable energy sources such as wind and solar power. These variable renewable energy (VRE) sources require energy storage options to match energy demand reliably at different time scales.

Switching Logic for a Direct Hybrid Electric Powertrain

open access: yesAerospace
Hybrid electric aircraft with a powertrain based on fuel cells and batteries can reduce climate-active emissions in aviation. In a direct hybrid powertrain, the fuel cell and the battery are connected in parallel, without a DC/DC converter balancing ...

Note on the pumped storage potential of the Onslow-Manorburn depression, New Zealand [PDF]

open access: yes, 2005
The Onslow-Manorburn depression in the South Island of New Zealand has possibility for development as the upper reservoir of the world's largest pumped storage scheme, as measured by an energy storage capacity of 10,200 GWh of realisable potential energy.
