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...]
Carbon Capture rates of 60% sound impressive. But rising carbon prices could still make you commercially unviable
Mainstream scenarios state the unavoidable need for continued use of fossils through to 2050. For the world to stay within its carbon budget, that means the unavoidable need for carbon capture and plugging “fugitive” leaks. Chris Bataille at the Center on Global Energy Policy flags up the danger that new CCS projects with seemingly impressive capture rates of up to 60% may nevertheless become commercially unviable as carbon prices rise: that … [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...]
Hydrogen’s innovation pipeline: signals strong ahead of World Hydrogen Summit in Rotterdam, May 9-11, 2023
The IEA and the European Patents Office have, for the first time, reported on patents filed worldwide to get a measure of the innovations we’re seeing in the hydrogen sector, summarised here by Ian Shine. Overall, Europe and Japan are leading. Although the U.S. is a close third, with 20% of the total, their filings have declined compared to the previous decade. The fastest growth is in China (15.2%) and South Korea (12.2%). There has been a … [Read more...]
Embodied Carbon Emissions: understanding the different methodologies being used around the world
The measurement of the embodied carbon emissions of goods tells us what greenhouse gas emissions are generated during the production and transportation of those goods. This achieves two main things. Firstly, it allows producers to understand where their emissions are coming from, and so reduce them. Secondly, it opens the door to putting a price on those emissions, thus incentivising producers to reduce them. But, as Max Gruenig at E3G explains, … [Read more...]
Steel decarbonisation: Australia must stop making excuses and follow Europe’s lead
Australian steel makers, major global exporters, must stop making excuses about decarbonisation and look to Europe for a role model, argues Simon Nicholas at IEEFA. A pattern of behaviour by Australia’s steel makers reveals that their excuse is that low-carbon solutions are not yet ready, leaving only promises of carbon capture (as yet unproven at scale) some time in the future. Nicholas notes that these promises will never have to be kept by the … [Read more...]
The U.S. should support the EU’s Carbon Border Adjustment Mechanism (CBAM)
The U.S. should get behind Europe’s Carbon Border Adjustment Mechanism (CBAM), says Joseph Majkut at the Center for Strategic and International Studies. Under the EU’s newest agreement, anyone importing CBAM-listed goods into Europe will have to report the emissions associated with their products starting in October, and ultimately face tariffs if those emissions exceed those of the equivalent products made in the EU. The current list is iron and … [Read more...]
Make Hydrogen in developing nations: share prosperity while meeting our climate goals
The new hydrogen economy will not just be global, it must be used as a major economic development opportunity for low income nations and promoting shared prosperity, explain Dolf Gielen, Silvia Carolina Lopez Rocha and Priyank Lathwal at the World Bank. They carefully lay out the obstacles and pathways for making hydrogen in developing countries. It’s very capital intensive, but such projects – think of existing fossil fuels, mining, etc. – have … [Read more...]
EU ETS and CBAM: what the big update to emissions trading rules means for Europe’s key sectors
The EU’s Emissions Trading Scheme is a vital part of the region’s decarbonisation plans. Simon Göss at carboneer digs into the new rules coming in for the existing EU ETS, and the implementation of the new carbon border adjustment mechanism (CBAM). Right now, the existing EU ETS covers around 40% of the EU’s emissions (energy sector, industrial installations and aviation). Its scope is being extended to include maritime transport. On top of that, … [Read more...]
CBAM needs universal adoption of methods for measuring carbon intensity
Europe needs to account for the emissions of imported goods. That cannot happen without the international agreement on standards and certification systems for the carbon intensity of all steps in the value chain for all relevant products. Dolf Gielen and Francisco Boshell at IRENA and Massamba Thioye at the UNFCCC explain that several such systems exist around the world, but they need to be harmonised and widely adopted to truly reflect what is … [Read more...]
EU’s Carbon Border Adjustment Mechanism lacks the detail to drive industry’s relocation near clean energy
High emissions industries should be relocated to where the cheap clean energy is. So long as the shipping costs (in terms of price and emissions) aren’t prohibitively high, those locations can be anywhere in the world. To get the calculations right, Carbon Border Adjustment Mechanisms (accounting for the emissions of imported goods) must be harmonised internationally. They must also – crucially – count all relevant emissions. But the EU’s draft … [Read more...]
