Pumped Hydro as a Battery
Hydro power is about 10% of the global energy production, but pumped hydro is being pursued as part of the solution for intermittent storage in renewable energy

High Voltage DC transmission systems are driving underwater power cable for renewable energy transmitted over thousands of km from Africa to UK or Australia to Singapore. Cheap solar is driving the change.
What is the real figure of amount of lithium in a battery. The quantity of 6kg is elemental lithium. The quanty of Lithium carbonate equivalalent or LCE is used in mining circles and the quantity is about 60 kg. A large opportunity for efficiency improvement is clear.
With established miners extracting lithium, who will be some of the up and coming miners. Here are 8 of them. There are another 150 miners globally.
Every new techology and disruption will have myths and falsehoods about how it will never happen. Here are 10 myths about electric cars – and many more to come.
Climate change myths are everywhere, given that $200 million a year is spent on climate denial by fossil fuel companies. Recognise the arguments and understand the tactics of fossil fuel companies to protect their stranded assets.
Airlines generally lose money. So electric, low carbon airplanes are being developed to reduce fuel costs – the largest cost after capital costs. What’s the latest development?
Home and community battery is a smart way to reduce transmission costs and to improve reliablity of renewable energy. Losses in transmission are about 10% and batteries cost much the same whether close to consumers or at a solar farm.
Recycling effectiveness is poor because companies have passed the responsibility and cost of recycle / reuse onto consumers. Less than 7% of all plastic is recycled. Almost as much is dumped at sea. Time to change.
When you dig into the supposed shortfall of lithium for EV and grid energy industry, it is clear that there is enough lithium to meet the demand although it will take time to come on stream.
There are 5 orders of innovation from individual components at order 1, to systems at 2, services at 3 to disruption of industry at order 5. Knowing this provides expectation of capital and time to market with new innovations.
What is FMG ulitimate goal? To change his low cost iron ore exports to China and turn it into green steel manufactured in Australia and exported globally? The company has been busy setting up deals and purchasing technology.
We pay over $11 billion a year for fossi fuel subsidies for direct support. That does not include the indirect subsidies. As well there are billions of dollars needed to remediate fossil fuel coal and gas mines. Who pays? Consumers
Electric trucks have been slowly entering the market from all the major manufacturers, and businesses are catching onto the savings and applications. Transition will be steady as the capital to change from conventional to electric will be intensive.
Some argue for nuclear as the basis of the Australian electricity energy but the data says nuclear would be more than 2.2 times the cost of renewable energy with sufficient battery storage of 20GW.
Direct Lithium extraction (DLE) provides faster extraction of lithium from brines, reduction of costs, increased recovery and opportunity for reduction in energy and carbon inputs.
Green hydrogen has 3 challenges to be part of the energy mix. a) cheap manufacture. b) cheap transport and c) applicable uses. That journey has started..
Freeing energy explores the energy in the world and shows how local free energy using PV panels and batteries will provide energy to 3 billion in energy poverty and disrupt 135 years of Big Grid.
Over 37 companies have announced or are building European battery gigafactories. The largest is Tesla at Berlin due for production in early 2021, but others are focused on supplying the European manufacturers.
Numerous battery gigafactories in the USA have been announced. With capacity over 1TWh they could build 15million electric vehicles per year.
