New York expects to change its future weather by installing lots of expensive mega-batteries, according to the Governor. But is fear of a harmless trace gas essential to life more like superstition than science?

The state has set a target to install 1.5GW of batteries by 2025, reports Energy Live News.

New York Governor Andrew M. Cuomo has announced an ‘Energy Storage Roadmap’ to guide the state toward its energy storage target of 1.5GW by 2025.

World’s first grid-scale liquid air energy storage plant goes live

Is this just another way of making renewable energy even more expensive, or what? The claim is that this “is a great step forward in the creation of a truly decentralized energy system in the UK allowing end-users to balance the national electricity network at times of peak demand”. Cranking up the boilers at the power station is going out of fashion along with the power stations themselves, but the price is high due to subsidies, and security of electricity supply is uncertain.

The world’s first grid-scale liquid air energy storage plant officially launched today, reports PEI.

The 5MW/15MWh plant near Manchester in England will become the first operational demonstration of liquid air energy storage (LAES) technology at grid-scale.

UK grid power balance to get support from 10MW battery

As the advance of subsidised renewables makes new gas or coal fired power stations ever less economic to build and operate, one of the supposed answers to the artificially created reliability problem is to add batteries to help ‘balance’ the grid. Of course this will also be expensive, and only marginally useful as batteries don’t generate their own power, but that’s just an issue for bill-paying consumers in the privatised UK energy system.

A battery installation at a UK biomass power plant is making news this month says TechXplore . Supporters call it an important recognition of the “enormous potential for battery solutions” in the UK.

The company is E.ON. The challenge, as they attempt to meet it, is doing their bit to balance the grid.

Tony Abbott’s victory as Australia dumps green energy target

Still trying to square the circle of unreliable, expensive renewables and reliable, affordable electricity supplies. At least one backbencher is starting to get it: “The problem with solar and wind … you’ve got to have them backed up in some way, and that’s either got to be a coal-fired power station, a gas generator or some form of battery.” And making batteries to the scale of power stations is neither practical nor affordable.

The details have not officially been released, but the ABC understands Prime Minister Malcolm Turnbull will argue his policy will lower electricity bills more than a Clean Energy Target (CET), while meeting Australia’s Paris climate change commitments, as the GWPF reports.

It is understood Cabinet last night also agreed to force retailers to guarantee a certain amount of so-called dispatchable power that can be switched on and off on demand, to avoid outages.

Vehicle to grid scheme allows EV owners to drive for free

What effect the extra demands of being used for energy storage might have on the long-term efficiency and life of the electric vehicle’s battery is not mentioned. They hope that more EVs on such schemes could reduce the need for new power generation, by allowing smarter management of existing resources.

Ovo, the UK electricity supplier, is to offer a ‘vehicle-to-grid’ service to buyers of the Nissan Leaf from next year, allowing electric car owners’ to drive for free by letting energy firms use their vehicle’s batteries, reports Power Engineering International.

Savings from the scheme will cover the £350-£400 annual cost of charging a Nissan Leaf, the electricity supplier told the Guardian.

The move could mean greater take-up of electric vehicles and help power grids manage the growth in green energy, according to its backers.

RWE planning 2.5 GW gas power plant in the UK

Former Tilbury power station

If this goes ahead it’s likely to be finished years before the troubled Hinkley Point nuclear plant.

German utility RWE has commenced the planning process for the construction of a 2.5 GW gas-fired power plant in Essex, England, reports Power Engineering International.

If the development is to proceed it would be a big boost for the UK energy system, as old coal and nuclear plants are being taken out of the equation.

RWE is starting the planning process to build a 2.5 GW gas power plant in Tilbury, Essex on the site of a former biomass station in what could be a potential boost to the UK energy system.

Grid-Level Electricity Storage – NOAA’s Critique of the WWS Vision

.
.
There’s the wind, water, and solar (WWS) vision promoted by a few academics, and then there’s economic and technical reality – with a seriously large chasm in between.

A new paper prepared by the U.S. National Oceanic and Atmospheric Administration’s (NOAA) Earth System Laboratory and published in the Proceedings of the National Academy of Sciences (PNAS) is drawing attention in policy circles in the U.S. The paper critiques the claims of a study by Mark Jacobson et. al. that it is feasible, at low cost, to achieve 100% conversion of the U.S. electricity generation system to wind, hydroelectricity and solar energy by 2050 (the “WWS Vision”).

The authors of the critique include experts in the National Renewable Energy Laboratory, who could not be accused of being “climate sceptics”. Indeed, they have previously authored reports in which they concluded that an 80% decarbonisation of the U.S. electrical grid eventually could be achieved at “reasonable” cost, assuming that a broad suite of generation options and other technologies are employed. Their critique of the Jacobson…

Coal mine to be transformed into 200 MW pumped hydro plant

What could possibly go wrong? Like all pumped storage, every ‘refill’ uses more electricity for the pumping than is generated by its water release. The UK is also looking to develop similar schemes. The motivation is the intermittency of renewables.

The German state of North-Rhine Westphalia is set to turn its Prosper-Haniel hard coal mine in Bottrop into a 200 MW pumped-storage hydroelectric plant reports PEI.

The facility will act like a battery and will have enough capacity to power more than 400,000 homes, according to state governor Hannelore Kraft.

Other mines may also be converted after Prosper-Haniel because the state needs more industrial-scale storage as it seeks to double the share of renewables in its power mix to 30 per cent by 2025, she said. North-Rhine Westphalia generates a third of Germany’s power.

US energy chief makes bold claim for storage technology

Is the world ready for organic flow batteries using extracts from rhubarb? PEI reports on some new electricity storage ideas hoping to save renewable energy from ultimate failure. ‘Holy Grail’ or wild goose chase – time will tell.

The US energy secretary, Ernest Moniz, believes the advances being made in storage technology means that the country will be completely decarbonised by the 2050s.

A global race, seen initially in Europe and the US is leading to a rapid acceleration in innovation that may dispense with the need for nuclear and thermal power by that time according to the technology’s backers, as the Achilles heel of intermittency will no longer impact on the overall effectiveness of renewables.

Nothing about costs, but let’s see how this demonstration project goes. The technology has already been tried in cars.

Europe’s first flywheel hybrid energy storage plant has been officially launched in Ireland, reports PEI.

The plant in Rhode, County Offaly, is owned and operated by Irish energy company Schwungrad Energie and is expected to enter a test operational phase in February.

E.ON begins construction of giant 5MW battery

Some might query whether 5 megawatts is ‘giant’ in terms of national electricity demand, and the usual claims that battery costs are going to drop like a stone are made, but nevertheless this attempt at an energy storage system is happening, as edie.net reports.

German energy company E.ON has started constructing the world’s first modular large-scale battery in the German town of Aachen.

The modular aspect of the design means that various battery technologies can be ‘plugged in’ to the system – a world-first for a battery of this size.

The Dearman Engine: Making Intermittent Generation Viable?

Claims of up to 70% efficiency have been made for converting ‘wrong time’ electricity produced by intermittent generators such as wind turbines to ‘right time’ electricity supplied onto the grid. The proposed storage medium is liquid air (with co2 and water vapour first removed. This -190C medium is used to drive a piston engine without combustion, and waste heat is re-used.
