US energy giant says renewables and batteries beat coal, gas and nuclear power

The energy industry is in the grip of massive change, with the cost of renewables and battery storage – without subsidies – beating gas, as well as existing coal and nuclear on costs. This is the view of Jim Robo, the CEO, president and chairman of NextEra, the biggest and most successful utility in the […]

Nedbank / EE Publishers seminar: Flexible power generation: A new paradigm in SA

Nedbank and EE Publishers are hosting a morning seminar on: Flexible power generation: A new paradigm in SA and an alternative to “baseloadism” This is the 4th in a series of important infrastructure seminars from Nedbank & EE Publishers DATE: Tuesday 22 October 2019 TIME: 09h00 to 14h30 (see detailed programme below) VENUE: Nedbank Main […]

The gas turbines/battery hybrid: Ideal partner for wind and solar

The increasing amount of renewable energy in networks has led to challenging situations which require flexible balancing generation plant that can respond rapidly to changes in generation and demand. Open-cycle gas turbines (OCGTs) have been used successfully in this function, but the growth of renewable energy (RE) in some networks has outstripped the ability of […]

The future of hydrogen: Seizing today’s opportunities

The time is right to tap into hydrogen’s potential to play a key role in a clean, secure and affordable energy future. At the request of the government of Japan under its G20 presidency, the International Energy Agency (IEA) has produced this landmark report to analyse the current state of play for hydrogen and to […]

Africa’s energy landscape transitions to base load-capable renewables

The advent of renewables, new storage technologies present Africa’s utilities with an opportunity to increase capacity and efficiency while re-kindling their appeal to investors.  There has been a clear and rapid evolution in Africa’s energy and energy infrastructure landscape over the last decade. While much of this new technology has challenged the traditional dominance and […]

Solid-state and polymer batteries 2019 to 2029: Technology, patents, forecasts 

A typical commercial battery cell usually consists of cathode, anode, separator and electrolyte. One of the most successful commercial batteries is the lithium-ion technology, which has been commercialised since 1991. However, their worldwide success and diffusion in consumer electronics and, more recently, electric vehicles (EV) cannot hide their limitations in terms of safety, performance, form […]

Pairing solar and storage challenges gas peakers

Gas peakers have been around even before the recent rise of renewables made them even more indispensible. How else could grid operators fill in the void created by the vanishing solar generation when the sun sets at the end of the day or when wind stops spinning the wind turbines’ blades? And with natural gas […]

Decline in storage costs “staggering”

If the most recent numbers are to be believed, gas-fired peakers will increasingly be challenged by battery storage devices. Although it should come as no surprise to anyone following developments in the solar and energy storage technologies, it does.  The latest technology cost analysis released by Bloomberg New Energy Finance (BNEF) shows that battery storage […]
