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 doesnât 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 EUâs â40% made at homeâ clean energy tech ambition
The EUâs Net Zero Industry Act wants to drive home-grown production of eight âstrategicâ 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 â and are already making moves to â 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. Itâs 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...]
âFlow Batteriesâ 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, âThe State of Clean Technology Manufacturing.â Itâs a global update on recent progress in key regions, focussing on five technologies â solar PV, wind, batteries, electrolysers and heat pumps â 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 theyâre the best option for overcoming grid constraints. And when theyâre 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. Itâs 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...]
Germanyâs 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 countryâs 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: âbook and claimâ 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 âchicken and eggâ 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 âbook and claimâ system can be the answer. Itâs 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. Itâs 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...]
U.S. EPA: new rules proposed for cutting Fossil Fuel-Fired Power Plant emissions
In May the U.S. Environmental Protection Agency proposed new rules regulating carbon emissions from fossil fuel-fired power plants. Here, four experts from the Center for Strategic and International Studies â Cy McGeady, John Larsen, Kyle Danish and Mathias Zacarias â make their assessment and point at the wide-ranging implications. The main issues covered include CCS, hydrogen-fuelled generation, state clean energy standards, carbon pricing, … [Read more...]
Financing Renewable Hydrogen globally: ramp up to 2030 only needs $150bn/year
Dolf Gielen, Priyank Lathwal and Silvia Carolina Lopez Rocha at the World Bank present a thorough review of the pathway to financing global clean renewable hydrogen over the coming decades. The wind and solar that powers production will continue to get cheaper, and so will electrolyser costs as they scale up. Nevertheless, the total financing will still be considerable. World Bank analysis shows around $30tn between now and 2050 will be needed … [Read more...]
Five charts on the Energy Transition: the 2020s is the decade of maximum disruption. By 2030 the endgame will be clear
Sam Butler-Sloss and Kingsmill Bond at RMI present a succinct summary of why the energy transition matters, how the 2020s is the era of maximum disruption, and how by 2030 the transitionâs endgame will be apparent (though far from complete). Four key technologies are already entering the exponential growth stage: solar, wind, EVs and heat pumps. As early as 2030 their cheapness will flush away the fossil equivalents in succeeding decades, say the … [Read more...]
Making Hydrogen direct from seawater using double-membrane electrolysis
Can hydrogen be produced from seawater? The standard method requires water to be purified, which is expensive to do and adds complexity to the device. David Krause at the SLAC National Accelerator Laboratory, Stanford University describes new research there that uses electrolysis and a double membrane directly on the seawater to separate out the chloride and isolate the hydrogen and hydroxides. The system operates without generating toxic … [Read more...]
The history of evidence of CO2-driven climate change starts in the mid-1800s
Marc Hudson at the University of Sussex gives us a fascinating review of the history of climate change science. While the Intergovernmental Panel on Climate Change (IPCC) was established in 1988, experimental evidence that CO2 traps heat dates back to the mid-1800s. The first predictions of global warming caused by humans came in 1895. The big change in perception took place in 1953. Canadian physicist Gilbert Plass (an academic whose career also … [Read more...]
Oil & Gas can meet 2030 net-zero target for only $600bn, quickly recouped. But itâs still not happening, warns IEA
The IEA summarises its 33-page report âEmissions from Oil and Gas Operations in Net Zero Transitionsâ. The IEA says the oil and gas sector needs ÂŁ600bn up front to meet its 2030 target of a 60% reduction in emissions. Thatâs only 15% of the sectorâs record 2022 energy-crisis windfall income. A small price increase and savings should recoup that money âquicklyâ, says the IEA. The IEA not only maps a way to limit the global average temperature rise … [Read more...]
