€30bn of Germany’s €130bn Corona economic stimulus package is dedicated to the energy sector and the climate. Simon Göss at Energy Brainpool runs through the four main areas of focus. There’s €11bn to fund a reduction in the EEG levy (renewables surcharge) to help electricity consumers. €9bn goes to creating a hydrogen industry for Germany. There’s €7bn to promote e-mobility (tax exemptions, subsidies, co-financing of charging stations and … [Read more...]
Energy conversion for Hydrogen cars is only half that for BEVs
Though Toyota may be a big fan, hydrogen cars have a problem. Energy must move from wire to gas to wire to power the car. There are always significant losses when the energy vector changes. For Battery Electric Vehicles (BEV) the energy stays on wires all the way to the car. Tom Baxter at the University of Aberdeen looks at the losses at each stage to show that for hydrogen only 38% of the original electricity gets used. For BEVs it’s 80%. … [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...]
Virtual blockchain for prosumers replicates a live utility-scale grid
Wayne Hicks at NREL describes research that’s created a virtual blockchain “prosumer” accounting system that replicates a live utility-scale grid. The goal of a real-world application is to allow countless individual households with their own electricity storage and generation to buy and sell power to each other; a truly revolutionary pathway. Clearly, it will require a system that securely accounts for vast amounts of transactions - a big enough … [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...]
Wireless recharging of EVs as they drive?
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
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...]
Investing for tomorrow, because Energy subsidies will decline 25% by 2050 – analysis
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
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
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
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?
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
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
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...]
