Which car firm will dominate the future? Tesla and its BEVs or Toyota with its hybrids? Schalk Cloete looks at the cost reductions coming down the line. He says that the hybrids have many more improvements on the way, whereas in terms of performance and efficiency the BEVs are already reaching their peak. Though further and considerable progress in battery technology is coming, it will benefit both. For city driving both will rely on battery … [Read more...]
Batteries’ next challenges: fast charging, vehicle-to-grid, long duration, second life
Li-ion battery storage costs continue to fall dramatically. But for batteries to fulfil their potential, particularly for grid storage, developers need to focus on fast charging, electric vehicle-to-grid capability, long duration storage and second-life batteries, explains Madeline Tyson at Rocky Mountain Institute. She runs through the different types of Li-ion batteries, their strengths and weaknesses, how they can be harnessed to address these … [Read more...]
Grid Battery tech on track. It now needs re-designed markets, monetisation
The rapid expansion of variable renewable electricity generation is making cost effective storage more urgent. Sure enough, in Europe several electricity storage projects are under construction and new ones are announced almost on a weekly basis. The battery technology seems to be on track, with estimates of $156/kWh in 2019 dropping to $61/kWh by 2030. But progress is hampered by the lack of a market that recognises and rewards the true value of … [Read more...]
Can Vanadium Flow Batteries beat Li-ion for utility-scale storage?
It’s taken 40 years for lithium-ion battery technology to evolve into its current state, powering everything from the smallest electronic devices to Tesla’s 100MW battery farm in southern Australia. But utility-scale Li-ion batteries are rare. 99% of grid storage today is pumped hydro, a solution that will always be limited by geographical and environmental constraints. For utility-scale chemical batteries to take off they need a new technology, … [Read more...]
From rooftop solar to carbon divestment, California leads the transition
California doesn’t wait for Washington. As America’s most populous state by far, it is behaving like a separate nation when it comes to climate policies. Tim Buckley, Director of Energy Finance Studies at IEEFA Australasia, says it has become a global leader in renewable energy. Renewables provided 34% of its total energy needs in 2018, and the business community sees economic success in further progress. The author runs through the highlights, … [Read more...]
VW joins Tesla and BMW – EV and energy company all-in-one pays for business and consumers
Last week’s announcement by VW that it is setting up a company called “Elli” (short for Electric Life) offering energy services shows VW’s vision of what lies ahead for the automotive industry. It brings them head to head with Tesla and BMW who are already playing a role outside the traditional bounds of the car business. They are the new breed, ready to profit from customers who want to go electric as long as it makes financial as well as … [Read more...]
