The German government is promising to publish a strategy on carbon capture, opening a door that has previously been closed to developing this technology. In the first of a series of articles, Simon Göss and Hendrik Schuldt at carboneer look at why the nation is changing its mind, before laying out the reasons why carbon capture will be essential for Germany to meet its emissions goals. Unlike the power grid, there’s no easy way to decarbonise … [Read more...]
Iron and Steel: how can Hydrogen and Direct Electrification replace fossil-based production?
Karan Kochhar, Luis Janeiro and Francisco Boshell at IRENA look at the decarbonisation of iron and steel. They account for about 7% of global energy–related carbon emissions. The authors explain what’s needed for green hydrogen and direct green electrification to take over from traditional fossil-based production. Many projects are in the pipeline, and the authors reference case studies like H2 Green Steel, SIDERWIN and Boston Metal. Though that … [Read more...]
Does Nuclear slow down the scale-up of Wind and Solar? France and Germany can’t agree
France and Germany lead the camps in disagreeing on the future of nuclear in Europe. Camille Lafrance and Benjamin Wehrmann at CLEW take a deep dive into the reasons why, quoting experts and politicians. Germany’s vision of a fully renewables-based EU is at odds with France’s unwavering support for low-carbon nuclear energy. European-wide agreement on targets matter because they drive future investment in the targeted technologies and the design … [Read more...]
The world needs 200,000 Offshore Wind turbines by 2050: mapping the locations, constraints
Hugo Putuhena, Fraser Sturt and Susan Gourvenec at the University of Southampton summarise the results of their methodology that determines where to locate the hundreds of thousands more offshore wind turbines the world needs to meet net-zero targets. The world may need as many as 200,000 offshore turbines by 2050, generating 2,000GW. At the end of 2022, 63GW had been installed worldwide, so that means 32 times current capacity. If the “power … [Read more...]
First-of-a-kind U.S. utility pilots community Geothermal to cut emissions and bills
For the first time in the U.S. a utility is piloting a community geothermal project to heat and cool 40 buildings and cut customers’ bills. Success will lead to scale up and replication, explains Adele Peters writing for the World Economic Forum. The case for community geothermal is very strong. Though geothermal’s up-front costs of installing pipes deep underground are high, running costs are low. The pilot, in Framingham (Massachusetts), will … [Read more...]
Circular Battery Economy: what policies and processes can accelerate recycling and reuse?
As battery production scales up so do the risks of the long global supply chain failing, or causing more emissions, damaging the environment, and breaching human rights. A circular battery economy should greatly reduce those risks. Yet the U.S. has no federal recycling mandates or requirements for lithium-ion batteries, and state policies are inconsistent. Marie McNamara at RMI maps out the five critical issues that must be dealt with. Before … [Read more...]
Draft EU rules on Battery lifecycle decarbonisation: close the loopholes!
Draft rules mean battery manufacturers selling into Europe will have to report the product’s entire carbon footprint, from mining to production to recycling, as early as July 2024. That data will then be used to set a maximum CO2 limit for batteries to apply from the end of 2027. This is a big step forward, says T&E, addressing concerns over battery carbon footprint and recycling, and it also covers environment and human rights. But T&E … [Read more...]
Norway’s Sleipner and Snøhvit CCS: problems expose limitations of the science, regulations and multi-decade commitment
The offshore carbon capture and storage (CCS) projects of Norway’s Sleipner and Snøhvit are often cited as good case studies for the viability of the technology. Other CCS hubs are being proposed from Malaysia to the North Sea to the Gulf of Mexico, larger by factors of 10 or more. But how viable are they? Grant Hauber at IEEFA summarises his in-depth report on the risks. Both Sleipner and Snøhvit, operating since 1996 and 2008 respectively, have … [Read more...]
“Battery Passports”: ensuring environmental sustainability, decarbonisation and mining labour rights
With battery production taking off, concerns are focussed on environmental sustainability, carbon footprint and labour rights where the raw materials are mined. Benedikt Sobotka, Co-Chair at the Global Battery Alliance and Robin Zeng, CEO at Chinese manufacturer Contemporary Amperex Technology, writing for WEF, describe the concept of the digital “battery passport” where compliance with the rules is certified and monitored throughout the life … [Read more...]
“Book and Claim”: how end consumers can pay distant producers for low carbon products
In long logistical chains (found in steel, concrete, aviation, shipping and others) end consumers that want to pay a premium to cut their emissions (for example to comply with corporate decarbonisation promises) often have no way to pay the first link in that chain to go low-carbon. “Book and Claim” creates a market to do that. Consumers buy certificates, and producers get the money to fulfil the commitment. And a working system will bring to … [Read more...]
Germany to ramp up the decarbonisation of Buildings Heating from Jan 1st 2024. How?
Decarbonising heating is a major challenge for any country. Germany’s Building Energy Act (GEG) means that from 2024 every newly installed heating system, in new or existing buildings, must operate with a minimum of 65% renewable energy. Concerns over the costs to customers (installing new and expensive systems, or paying a penalty for fossil heating) has led to intense debates, hence the new law includes a range of subsidies, bonuses, discounted … [Read more...]
Only certain types of Hybridisation (Wind or Solar + Storage) beat building expensive transmission lines
In some regions, the roll out of new wind and solar has outpaced new transmission. That causes “congestion” at times when the variable renewables are producing too much power locally, and cannot sell the excess, which squeezes profitability. That’s certainly the case in the U.S. now. One answer is “hybridisation” where storage is built alongside the renewables, to save that excess power for when it can be sold later. Julie Mulvaney Kemp at … [Read more...]
France plans the social leasing of EVs at €100/month. Can it jump start affordable electric cars?
Social leasing of EVs could become the breakthrough example of climate action done right, explains William Todts at T&E. And France’s president Macron has promised to do it, aimed at low-income households to counter criticism that even with subsidies EVs are still out of reach for many. Todts quotes T&E analysis that shows that between 2024 and 2030 around 900,000 low-income households could benefit from monthly leasing costs of €70 to … [Read more...]
Nuclear power capacity is growing globally. Where, how and why
Ewan Thomson at the World Economic Forum summarises the state of nuclear power worldwide. In 2020 it made up 10% of global electricity generation, more than all the wind and solar PV combined. It’s the second-largest source of low-emissions electricity. But many advanced countries are no longer backing nuclear, citing safety and cost concerns, and instead are pushing the growing number of alternative clean energy technologies. Nevertheless, … [Read more...]
Building Materials “Embodied Carbon”: reaching net-zero with low-carbon cement, timber, modular design and more
In this explainer Madeline Weir, Audrey Rempher and Rebecca Esau at RMI first describe how embodied carbon is calculated. They then summarise the strategies being employed to reduce it, including using low-carbon, carbon-neutral, or even carbon-storing materials. New cement formulations are being developed with over 60% less CO2 emissions than the regular kind. Low-carbon mass timber is an alternative building material under development. On the … [Read more...]
