Detroit-based Bollinger Motors’ versatile E-Chassis for electric vehicles could pave the way for a commercial vehicle fleet transition in the U.S. which accelerates the e-mobility revolution.

The material was used by scientists in the U.S. in electrochemical cells which use electricity to separate steam into hydrogen and oxygen. The researchers say the oxide of perovskite used in the electrode improves cell performance and reduces operating temperatures.

The effect the coronavirus pandemic is having on energy systems and environmental policy in Europe was discussed at a recent machine learning and climate change workshop, along with the help artificial intelligence can offer to those planning electricity access in Africa.

Scientists in South Korea have worked with graphene and carbon nanotubes to develop a working lithium-ion battery that can be stretched by up to 50% without damage to any of the components. According to the scientists, the battery represents a significant step in the development of wearable or body-implantable electronic devices.

The Australian Energy Market Operator (AEMO) claims that the country already has the technical ability to safely operate a system in which three-quarters of the electricity comes from wind and solar. However, it needs to get the regulations right in order to do so.

Analysts at Bloomberg New Energy Finance say the lowest-cost projects financed in Australia, China, Chile and the UAE in the last six months hit a levelized cost of energy of just $23-29/MWh and the best solar and wind projects will produce electricity for less than $20/MWh by 2030.

Scientists from Singapore have developed semi-transparent perovskite solar cells that can be easily integrated into a range of urban contexts, including building facades, gates and windows. The 21cm2 mini panels are made of perovskite solar cells based on methylammonium lead iodine (MAPbI3), with an efficiency of 20.28% for 0.16 cm2.

A study from Finland’s Lappeenranta University of Technology states decarbonization of desalination could help achieve a levelized cost of water of €0.32-1.66 per cubic meter. Solar and storage are expected to play a decisive role.

Matt Harper, chief commercial officer of newly-merged British-Canadian vanadium redox flow battery business Invinity Energy Systems has spoken to pv magazine about the VS3-022 Battery Unit it is marketing for grid scale solar-plus-storage projects and why it may be a better bet than lithium-ion.

Researchers at the Queensland University of Technology have proposed a new design for a diamond nanothread bundle that could pave the way for a new form of mechanical storage. Pound-for-pound, the tech could be three times more powerful than lithium-ion batteries.
