Households need the right tools to be able to take control of their real-time energy consumption, says Maximilian Auffhammer at the Energy Institute at Haas. Smart meters are just too crude. They don’t tell you how much energy individual devices are using – fridges, ovens, heaters, EV chargers, TVs, lightbulbs, toasters, etc. You have to work it out yourself by switching devices on and off and seeing the difference. Auffhammer argues if you price … [Read more...]
Evidence of a direct link between Wildfires and Fossil Fuel firms. Can it be used to sue them?
Wildfires are back in the news. The link to rising global temperatures caused by climate change is clear. Mark Specht at the Union of Concerned Scientists summarises their study that, for the first time, puts a number on the level of responsibility attributable to fossil fuel companies. Rising temperatures create a “vapour pressure deficit,” a measure of the power of the air to dry out plants and trees. That leads to an increase in the area … [Read more...]
Lookahead to 2024 27-nation EU Parliamentary elections: will ambitious climate policies win or lose votes?
In June next year Europeans from 27 nations will elect a new EU Parliament that will shape the bloc’s energy and climate policy in the years leading to the 2030 climate target deadline. It’s not clear whether rising prices, energy security and heatwaves will steer votes towards parties pushing for more rapid decarbonisation, or whether the cost and disruption of transition will do the exact opposite. At the last election in 2019 climate concerns … [Read more...]
Power to the people: citizen-centred Just Transitions challenge energy system centralisation
EU Member States need to phase-out coal and transform their carbon-intensive industries to make Europe climate-neutral. However, these should not be the only goals: transparency and justice must also accompany this path, argue Diana SĂĽsser at IEECP, Serafeim Michas at TEESlab and Ricardo Antonio GarcĂa Mira at the University of A Coruna. As Member States implement their territorial just transition plans, they must ensure they benefit affected … [Read more...]
Ammonia from water microdroplets: lab demonstrates cheap, low-tech production
Very early stage research has discovered a new way of making ammonia cheaply, on a small scale (or large, if you want!), and with no harmful emissions, explains Adam Hadhazy writing for Stanford University. The process uses a cocktail of water, nitrogen gas, and a solid catalyst sprayed through a simple, low-tech instrument to make the ammonia. In contrast, the existing industry-standard Haber-Bosch process is energy intensive, large scale, and … [Read more...]
U.S. Heat Pump adoption is evenly spread across rich and poor. Surprised?
The problem with subsidising first-adopters of new technologies is that they can substantially benefit rich households. They’re the ones who buy the first EVs, rooftop solar, etc. Lucas Davis at the Haas School of Business presents data that shows that, in the U.S., heat pumps are being bought evenly across the income distribution. This is a surprise, not least to the author! Nationwide, 15% of households have a heat pump as their primary heating … [Read more...]
EU’s 40% domestic Cleantech ambition: same target for Wind (easy) and Solar (hard) doesn’t make sense
The proposed Net Zero Industry Act includes a target for the EU to manufacture domestically at least 40% of its cleantech deployment needs by 2030. That includes the key technologies of solar PV panels, wind turbines (onshore and offshore), EV batteries, heat pumps and hydrogen electrolysers. But it doesn’t make sense to have the same 40% target for all, explain Giovanni Sgaravatti, Simone Tagliapietra and Cecilia Trasi at Bruegel. The main … [Read more...]
How will China respond to the EU’s “40% made at home” clean energy tech ambition
The EU’s Net Zero Industry Act wants to drive home-grown production of eight “strategic” net-zero technologies, including solar, wind, batteries and CCS. The target is 40% made at home, though the policy is yet to be worked out. You Xiaoying writing for China Dialogue talks to experts in China and the EU for their predictions. Most say that Chinese firms are not very worried. Firstly, they can – and are already making moves to – set up production … [Read more...]
Steel, Aluminium: 20% of emissions reductions target must come from Recycling. How?
Recycling is needed to achieve 20% of the emissions reductions targets for the steel and aluminium sectors. It’s an integral part of the 1.5°C climate-aligned decarbonisation pathways in many metal sectors, explain Sravan Chalasani, Wenjuan Liu and Lachlan Wright at RMI. For aluminium products, the share that comes from post-consumer scrap needs to increase from 21% in 2020 to 46% by 2050. Recycling is already a reality, but reporting and … [Read more...]
“Flow Batteries” for grid-scale storage: modelling cheaper alternatives to Vanadium
Flow batteries are a promising new technology for grid storage. Rather than the standard batteries that store charge in a solid material, they use a solution to store that charge, making large-scale long-duration electricity storage much easier. Vanadium electrolytes have been the preferred choice so far, but affordable supplies are limited and a cheaper alternative will be needed for global scale-up, explains Nancy Stauffer at MIT who describes … [Read more...]
IEA report: global manufacturing capacity is expanding rapidly for solar, wind, batteries, electrolysers, heat pumps
The IEA summarises its special briefing, “The State of Clean Technology Manufacturing.” It’s a global update on recent progress in key regions, focussing on five technologies – solar PV, wind, batteries, electrolysers and heat pumps – critical to the energy transition. It should be read to keep decision makers informed of investment trends and the impact of industrial strategies. Overall, manufacturing capacity for these technologies is expanding … [Read more...]
Community Batteries: when they’re the best option for overcoming grid constraints. And when they’re not
Community batteries are a shared asset in neighbourhoods with rooftop solar, avoiding the need for every household to have its own battery. Even people unable to have rooftop solar can use it. It’s taking off in Australia, supported at both the state and federal level. But Bjorn Sturmberg, Alice Wendy Russell, Hedda Ransan-Cooper, Louise Bardwell and Marnie Shaw at the Australian National University summarise their research which warns that it … [Read more...]
Germany’s proposed de facto ban on new fossil boilers from 2024 meets fierce resistance
Like many nations, Germany is struggling to find a way to replace fossil fuel-powered boilers in millions of homes and buildings with heat pumps and other cleaner alternatives. Heating accounts for a whopping 15% of the country’s emissions. As Sören Amelang at CLEW explains, the up-front cost of a new clean heater can be double that of existing mass-produced fossil equivalent, so home owners are resistant. In 2022, two thirds of all new heating … [Read more...]
Decarbonising Shipping: “book and claim” pilot uses clean fuel tokens that move from cargo through to fuel producers
Switching to clean alternative fuels is the key component of the decarbonisation of shipping. But it faces the classic “chicken and egg” problem of who moves first: the fuel producers, the refuelling ports or their customers the ship and cargo owners. Aparajit Pandey and Oscar Hernandez at RMI explain how a “book and claim” system can be the answer. It’s already proven itself in electricity markets and the aviation sector. Digital tokens are … [Read more...]
Perovskite: abundant, cheap, printable solar cells demonstrated, ready to generate power
Laboratories around the world are racing to make printable perovskite solar cells, produced in abundance and so thin they can be wrapped around almost anything. It’s a huge advantage over the typical silicon cell that is relatively big and fragile. And perovskite is much less expensive to produce. David Beynon at Swansea University describes research there that has demonstrated how a roll of plastic film can be loaded into a printing press to … [Read more...]
