Globally, new installations of grid storage fell year-on-year in 2019 for the first time since 2013. This IEA summary of the landscape is taken from its latest series of Tracking Clean Energy Progress reports. The IEA’s recommendations reflect the fact that grid storage is new and complex, needing changes to existing regulations and market rules that are unviable in the age of transition. The policy goal is to monetise the value of storage in … [Read more...]
Tipping Points reached for Solar, Wind, Batteries, EVs. What of the other Clean Energy techs?
History shows a disruptive technology’s tipping point can be under 5% of market share, that’s all it takes. The number of horses in use peaked in the U.S. once car ownership reached 3%. Gas lighting in the UK peaked with electric lighting at just 2% of the market. Landline phones in the U.S. fell precipitously after mobiles captured 5% of the market. Ji Chen and Koben Calhoun at RMI argue the tipping point has already been passed for solar, wind, … [Read more...]
Grid-scale Solar PV storage can use re-purposed old EV batteries
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...]
Clean Energy threatened by lockdown of critical minerals supply
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
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...]
U.S.: Counting Renewables jobs and projects under threat, what can be done and why
All sectors across all economies are trying to add up their potential job losses and projects in jeopardy, then telling their governments to prioritise them for Covid lockdown support. Mike Jacobs at the Union of Concerned Scientists looks at renewables in the U.S. He quotes news reports that over 100,000 workers in this fast-growing industry filed for unemployment in March 2020. On top of that, the already planned expiry and phase-down of … [Read more...]
Designing the Covid-19 stimulus: what the 2008 crisis can teach us
Policy makers around the world are hearing a lot of advice on how to design their stimulus packages. This comes from the IEA where Fatih Birol lays out five fundamental lessons we can learn from the stimulus packages that came out of the 2008 global financial crisis. His main headings are: Build on what you already have – and think big (e.g. feed-in tariffs, production tax credits); Choose technologies that are ready for the big time (e.g. wind, … [Read more...]
Green Ammonia can replace fossil fuel storage at scale
What’s the best way to store energy, from industry scale to electric vehicles, replacing the widespread use of fossil fuels? Pure hydrogen is an energy dense alternative, but the gas takes up a lot of space. Liquid ammonia doesn’t, yet it contains the hydrogen and therefore the energy. Ian Wilkinson at Siemens explains the advantages of using ammonia, NH3. Already the world produces 180m tonnes a year, worth €80bn. It’s mainly for agricultural … [Read more...]
How much subsidy do EVs need to be competitive?
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...]
Europe needs its own EV battery recycling industry
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...]
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...]
New EU Industrial Strategy focuses on emissions, but is it enough?
This month the European Commission released its new EU Industrial Strategy to set the direction of travel for the EU economy in the context of the European Green Deal. Energy-intensive industries - like steel, cement, aluminium, paper and chemicals - account for roughly 17% of EU emissions and have struggled to reduce them in recent years. But Johanna Lehne at E3G doubts the strategy is enough to meet the ambition of becoming the first … [Read more...]
Multi-energy “island” Microgrids can increase grid resilience
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...]
Pumped Thermal Electricity Storage: grid-scale, cheap materials, known tech, compact, install anywhere
We need to store the huge quantities of excess electricity generated by variable renewables. But what’s the best way? Currently, over 99% of large-scale electricity storage uses pumped hydro dams. But geography severely limits where you can build one. And the growth of grid-scale batteries is limited by raw material costs and short lifecycles. Antoine Koen and Pau Farres Antunez at Cambridge University review an important alternative, Pumped … [Read more...]
“All new vehicles sold must be electric by 2030” but can your nation, state, city do it?
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...]
