Wind and solar need cheap, long-duration storage to even out its inherent weather-determined intermittency. Deborah Halber, writing for MIT News, describes the development of iron-air batteries. Iron is cheap and available worldwide. Storage duration is multi-day. They are much heavier and take up more space than lithium-ion batteries, but that doesn’t matter for immobile grid storage. The target price tag of $20/kWh (one-tenth the cost of … [Read more...]
Green Steel: pathways for the new hydrogen-powered DRI-EAF projects
H2-DRI-EAF uses hydrogen (H2) to produce direct reduced iron (DRI), which is then processed in an electric arc furnace (EAF) to produce steel. The two main challenges are ensuring an adequate supply of DR-grade iron ore, and cutting the end-to-end cost of making hydrogen. But right now, clean green hydrogen production is in its infancy, and therefore so are green steel plans. Soroush Basirat at IEEFA surveys the landscape, looking at the U.S., … [Read more...]
Iron Ore miners try different multi-billion strategies to lower emissions for Steel producers
2024 should see a further acceleration in steel’s transition away from coal, with increasing pressure on companies in the value chain to act on their Scope 3 (indirect) emissions, explains Simon Nicholas at IEEFA. Old coal-fired blast furnaces that use low-grade iron ore are already being replaced with the direct reduced iron (DRI) process in Europe and China. That means the “big four” iron ore miners have to ramp up production of high-grade iron … [Read more...]
Buying carbon allowances while decarbonising: what’s the best strategy for an EU industrial firm?
EU industrial companies affected by the big changes to their carbon costs that come from the new EU ETS rules and the Carbon Border Adjustment Mechanism (CBAM) must create strategies to deal with them, if they haven’t started already. Otherwise they will fall behind those that have. Pablo Ruiz at Rabobank summarises their analyses and conclusions. Ruiz presents a map for each of the different starting positions. The study looks at the critical … [Read more...]
Middle East & Africa to export Hydrogen to Europe? Better to make green Iron & Steel and export that
The MENA region (Middle East and North Africa) is well suited to making green hydrogen. There’s huge potential for powering green hydrogen production with cheap solar. And Europe wants to import it. But Soroush Basirat and Simon Nicholas at IEEFA argue that MENA should use the green hydrogen to make green iron and steel and export that. It already has an established direct reduced iron (DRI) sector: now powered by gas which can be swapped out for … [Read more...]
How much protection from carbon-intensive imports will CBAM give to EU industries?
The EU’s Carbon Border Adjustment Mechanism (CBAM) is not a business-as-usual instrument that allows sectors to delay decarbonisation. It applies a levy on imported goods equal to the internal EU ETS-related carbon price, so that both EU-produced goods and those imported into the EU face similar carbon cost pressures. But sectors must use the CBAM phase-in period to decarbonise. Pablo Ruiz and Barbara Kölbl at Rabobank look at how different … [Read more...]
CBAM is now active. A guide to what companies must do to comply
On October 1st 2023 the Carbon Border Adjustment Mechanism (CBAM) became effective. Its purpose is to limit carbon leakage by establishing a carbon price on imported goods that is equivalent to the carbon price on domestically produced goods. That means introducing a set of reporting and compliance obligations for importers of goods into the EU. Simon Göss and Hendrik Schuldt at carboneer explain the new mechanism and scope (aluminium, cement, … [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...]
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...]
