Grid-scale Solar PV storage can use re-purposed old EV batteries

May 28, 2020 by David Chandler

Once an EV battery has declined to 80% of its original capacity it is considered too weak for continued vehicle use. Recycling the battery – at that point - to make another one is expensive. MIT’s David Chandler describes how researchers there have run experiments and models to show that old EV batteries can instead be packed together and used as backup storage for grid-scale solar PV installations. It’s cheaper than building new Li-ion battery … [Read more...]

Wireless recharging of EVs as they drive?

May 19, 2020 by Edmund Andrews

Engineers have demonstrated a practical way to use magnetism to transmit electricity wirelessly to recharge electric cars. Stationary wireless EV charging has already been piloted and promoted by companies like Connected Kerb in the UK and car manufacturers. Experiments with the mobile version have also been conducted. Clearly, the less often an EV has to stop to recharge the better. But this has run into the problems of energy conversion … [Read more...]

Clean Energy threatened by lockdown of critical minerals supply

May 14, 2020 by Tae-Yoon Kim and Milosz Karpinski

Clean energy technologies depend on the reliable and growing supply of critical minerals and metals, far more so than the old fossil fuel world. An EV uses five times the quantity needed by a conventional car, and an onshore wind plant requires eight times that of a gas-fired plant of the same capacity. Hence, electric transport and grid storage are now the largest consumers of lithium and cobalt. Examples of rising consumption abound for other … [Read more...]

Latest data shows lifetime emissions of EVs lower than petrol, diesel

May 12, 2020 by Eoin Bannon

Critics of the rapid roll out of electric vehicles correctly say that their factory door emissions (i.e. CO2 emitted during manufacture) are higher than those for standard petrol and diesel cars. Then you have to add the emissions of the local grid (how renewable is it?!) that’s charging your EV. But the numbers behind those calculations are always changing. Eoin Bannon at Transport and Environment describes the findings of their new tool that … [Read more...]

Investing for tomorrow, because Energy subsidies will decline 25% by 2050 – analysis

May 8, 2020 by Michael Taylor

IRENA has modelled energy subsidies to 2030 and 2050 for their pathway to meet the Paris targets. Here, Michael Taylor summarises their findings. Firstly, they estimate today’s global direct energy sector subsidies to be $634bn/year (2017 figures). The vast majority, $447bn, went to fossil fuels. (By the way, he points out that none of these figures include the externality costs - pollution, healthcare, environment - which equate to trillions and … [Read more...]

IRENA’s Global Renewables Outlook and how Europe can lead the way

May 1, 2020 by Gayathri Prakash, Nicholas Wagner and Ricardo Gorini

If the coronavirus slump has knocked everything off track IRENA’s first ever Global Renewables Outlook is a timely reminder of what that track should look like. It can help policymakers design stimuli packages that will get us back onto it, and even accelerate the transition. IRENA’s Gayathri Prakash, Nicholas Wagner and Ricardo Gorini run through the comprehensive report’s main recommendations. Annual investment, shares and GW targets to 2030 … [Read more...]

Accelerate EV infra, buildings refits to use electricity’s looming spare capacity

April 17, 2020 by Chris Nelder

How do we turn the pandemic downturn into an executable opportunity, above and beyond targets and promises? Chris Nelder at RMI presents data on how electricity load has dropped during the lockdown in the U.S. That load will return when the economy recovers. In the interim capacity will go unused. New capacity in the pipeline could be delayed. Nelder suggests policy makers grasp the opportunity to fill that gap and use that capacity by directing … [Read more...]

Behaviour Change: Covid-19 lockdown kicks open the door to a net-zero pathway

April 14, 2020 by Schalk Cloete

Working from home and minimal travel are “no brainer” ways to drastically reduce emissions. They’ve never been tried on a nationwide scale anywhere. Now they are, everywhere. Everyone is doing their best to make it work. Next, food waste should also be in decline, hopefully. Even if panic stockpiling happens, people’s mindsets are being changed as they try to use everything they’ve bought. The act of re-thinking what and how much we eat, in every … [Read more...]

How much subsidy do EVs need to be competitive?

April 7, 2020 by Schalk Cloete

Despite a wide range of subsidies and incentives, battery electric vehicles (BEV) make up only 1.4% of new car sales in the U.S. That the effective battery cost is zero to the consumer doesn’t seem to be lifting that number any higher. Meanwhile, in Norway the percentage is a much more impressive 42%, but those subsidies and incentives are far higher: the effective battery cost is negative 385 $/kWh for a typical 60kWh battery pack, i.e. a very … [Read more...]

Covid-19 and the EU car industry: any support should lock in EV targets

April 1, 2020 by Julia Poliscanova

The coronavirus slump has come suddenly and hit hard. The deep thinking has already begun on the economics needed to turn around that slump without damaging our rising emissions ambitions. Julia Poliscanova at Transport & Environment looks at the car industry. Some have called for the new CO2 standards coming in 2020 to be postponed (though, notably, VW and BMW still support them). She explains that total car sales were already declining in … [Read more...]

Europe needs its own EV battery recycling industry

March 25, 2020 by Raphaël Danino-Perraud

Europe needs its own battery recycling industry, and the EU’s European Battery Alliance should make it happen, says RaphaĂ«l Danino-Perraud writing for the IFRI Centre for Energy & Climate. For economic, strategic and environmental reasons, today’s overwhelming dependence on outsourcing – in this case to Asia - for battery manufacture and recycling needs to change. To start with, Asia provides over 90% of global car battery output, half coming … [Read more...]

China’s 2019 electricity generation reviewed as its next 5-year plan is drafted

March 24, 2020 by Simon Göss

Simon Göss breaks down the totals and additions for electricity generation in China. In 2019 the total reached 7,325 TWh (more than twice Europe’s) after adding 330 TWh (more than half Germany’s total). Of that 330 TWh, 120 TWh came from thermal (90%+ coal). But the numbers were dominated by renewables (hydro, wind, solar) which added almost 160 TWh. Though that’s the third year of declining renewables additions, wind and solar curtailment is … [Read more...]

Are national fossil fuel car bans compatible with EU laws, intra-trade, movement?

March 12, 2020 by Eoin Bannon

A growing number of EU nations are announcing laws to phase out the sale of new fossil fuel cars within the next 20 years. But are the proposed bans compatible with EU laws, or even workable given cross border trade and movement rights? If you are Dutch, why not buy your new petrol car in Belgium, then drive it back to the Netherlands? How do you enforce CO2 targets with foreign haulage fleets transiting through your nation? Eoin Bannon at … [Read more...]

Multi-energy “island” Microgrids can increase grid resilience

March 11, 2020 by Xi Zhang

As the number of different technologies producing power and providing storage increases, the grid is getting complicated. The best way to make it resilient against outages is therefore changing. The traditional way is to shut down the failing plant, leaving the rest of the grid to cope as best as it can with the change in voltage and frequency. Xi Zhang at the Energy Futures Lab, Imperial College, describes the research looking at multi-energy … [Read more...]

“All new vehicles sold must be electric by 2030” but can your nation, state, city do it?

March 3, 2020 by James Conca

More and more nations, states and cities are announcing plans for the ramping up of EV adoption. Jim Conca takes a look at his home, Washington State in the U.S., where all new vehicles sold must be electric by 2030. He says the new rules imply his state will have 4 million EVs on the road by 2045, up from 52,000 today. He carefully crunches the numbers to see if this target is realistic. The good news is that grid capacity will only need to rise … [Read more...]
