Energy-intensive industries that invest in their own large on-site batteries will provide multiple benefits to themselves as well as to grid stability, says a new study by the Joint Institute for Strategic Energy (JISEA) in partnership with NREL and others. It matters because future power systems will need to be highly flexible due to the variability of wind and solar. The study assessed two established energy-intensive industries (chlor-alkali … [Read more...]
Distributed Energy Resources and Smart Grids: an opportunity or a distraction?
Distributed Energy Resources (DERs) are poorly understood by the utilities, explain Doyob Kim and Alyssa Fischer at the IEA. Part of the problem is that new innovations and solutions are coming fast, and policy-makers aren’t creating the incentives and frameworks to make them an imperative. But, done right, the successful integration of DERs into the grid will accelerate electrification, address grid stability, and reduce spending on expensive … [Read more...]
Compact voltage converters for integrating new DERs into the grid
The switches and converters needed to plug new clean energy technologies into the grid are going to be needed soon. The cheaper and smaller they are, the easier it will be to cope with the wide range of solutions coming down the pipe. NREL and its partners are building a megawatt-scale prototype converter that could fit the bill. They will be 1/5th the size and 1/10th the weight of existing alternatives: small enough to place almost anywhere. … [Read more...]
Clean transport in Europe: key trends to watch out for
T&E’s quarterly trends series gives a snapshot of the key developments that will define the future of clean transport in Europe. And what Europe does – given it wants to lead this field – should influence what happens worldwide. T&E’s Thomas Earl brings attention to four issues. First, proven progress in this major sector makes it a contender for a significant role in Europe’s new industrial strategy. It ranges from battery and … [Read more...]
New cooling system for inverters brings electric Heavy-Duty Trucks closer
39% of greenhouse gas emissions in the transport sector comes from heavy-duty trucks. Commercial batteries struggle to deliver enough power to make electrification feasible for heavy-duty applications. Rebecca Martineau at NREL explains how a working prototype, developed with the heavy machinery manufacturer John Deere, is now getting a 378% increase in power density. The key to the innovations rests on a state-of-the-art thermal management … [Read more...]
Ice for storage for intermittent renewables, then for cooling
Cooling accounts for around a fifth of total energy consumption in buildings. All those air conditioners and electric fans make up a tenth of all global electricity consumption. Demand will keep rising as developing nations get wealthier. Andrea Willige, writing for the World Economic Forum, looks at ice as a seemingly simple solution. Ice can be used as an energy store like a battery, to balance the grid. Create it when energy is cheap (at … [Read more...]
Nanochemistry breakthrough could lift energy density of batteries by factor six
Finding new ways for batteries to increase the charge they can store will lift their energy density. Researchers at Stanford University have developed an alkali metal-chlorine battery that stores six times the charge of today’s commercially available lithium-ion batteries. Until this breakthrough, a high-performance rechargeable sodium-chlorine or lithium-chlorine battery has been impractical because chlorine is too reactive to convert back to an … [Read more...]
Can Aluminium-air batteries outperform Li-ion for EVs?
Aluminium-air (Al-air) batteries for cars are an innovative technology that automakers and policy-makers should take a close look at, say Helena Uhde and Veronika Spurná at ECECP. Although a battery, they behave more like an engine: the fuel is the aluminium which reacts with the air via an electrolyte to produce electric power. Al-air has big advantages over a lithium-ion battery, the favoured choice for EVs. It has a travel range similar to … [Read more...]
Electric Micromobility: how to cut emissions, create jobs and transform urban transport
What if e-bikes, electric scooters and electric skateboards were added to walking and cycling in our attempts to reduce emissions through behaviour change? It’s a promising solution for all those people who genuinely want to reduce their emissions but don’t want the extra exercise. Quoting from their report, Jennifer Dungs at EIT InnoEnergy looks at the gains to be made, along with a valuable reduction in city congestion. Micromobility is still … [Read more...]
EU: Slow-moving CO2 targets for cars put EV battery boom at risk
Europe’s battery manufacturers are positioning themselves to be global leaders. Their project pipeline will be enough to power a new European car fleet that is 75% battery-electric by 2030. That’s 38 European gigafactories by 2030 (fully funded, part-funded and proposed), €39.5 billion worth in investments, creating 44,000 direct factory jobs. But existing CO2 emissions cut targets imposed on car manufacturers – a leading driver of demand for … [Read more...]
Biden’s major report on critical minerals supply: domestic mining + processing, innovation, EVs, global allies + more
In June, The White House issued its 250-page report on the global critical minerals supply chain, and how the U.S. can ensure continued supply as well as build up its own mining and manufacturing base. It is the fullest picture so far of how the U.S. is evaluating mineral access and supply chain resilience, says Reed Blakemore at the Atlantic Council Global Energy Center. Here he reviews the report, in particular the section on energy which … [Read more...]
How to grow grid-scale U.S. Battery capacity to 125GW (or even 680GW) by 2050
Grid-Scale U.S. storage capacity could reach 125GW by 2050, or even as much as 680GW, according to research from NREL. Almost all today, under 25GW, comes from pumped hydro which has probably reached its limit so the future is batteries. Growth depends on commercial viability, so the research led by NREL has modelled what services storage can supply, the main three being firm capacity, energy time-shifting and operating reserves. The sets of … [Read more...]
What patents tell us: which countries, what sectors, are the clean energy innovators?
Today’s solutions cannot give us a successful transition on their own. That’s why the innovations coming down the pipeline are so important. One way to measure what, and who, is innovating is to look at the number of patents being filed for low carbon energy (LCE), explains Sean Fleming writing for the World Economic Forum. He summarises the latest report from the European Patent Office and the IEA, “Patents and the energy transition: Global … [Read more...]
Clean Hydrogen from water electrolysis: research into catalysts to meet global targets
The full potential of the new hydrogen economy will depend on producing enough clean hydrogen from water electrolysis which uses precious metals. But, as Glennda Chui at SLAC (Stanford University & DoE) explains, there aren’t enough precious metals in the world to get to the scale we need. And their cost is so high the clean hydrogen they generate could never compete with hydrogen derived from fossil fuels. Over 95% of hydrogen produced today … [Read more...]
Green EV Batteries: tighter rules can advantage and boost manufacturing in Europe
Policies like the “green” labelling of EV batteries would give a significant advantage to European manufacturers, as well as accelerate the cleaning up of the supply chain. EU firms are better than most foreign battery manufacturers at monitoring and reducing emissions, writes Carole Mathieu at the IFRI Centre for Energy & Climate, referencing her report “Green Batteries: A Competitive Advantage for Europe’s Electric Vehicle Value Chain?” The … [Read more...]
