Is Sweden's Green Steel Transformation still on Track?
The Swedish state mining company LKAB is delaying some of its more ambitious plans for a green steel transformation. However, other green steel projects in the Nordic country are proceeding.
From Coal enabler to the Minimal Green Methanol Economy
While it does not get as much attention as hydrogen, green methanol could play a crucial role in a climate-neutral industry. Ideas for a Methanol Economy have been around for decades, but the implementation challenges should not be underestimated.
Why no one wanted to buy the Green Shipping Fuel
Many shipping companies see e-methanol - made from hydrogen and carbon dioxide - as the most promising future clean fuel. But it appears they do not want to buy it: energy company Ørsted canceled plans for an e-methanol production facility due to a lack of offtake agreements. A weakened EU regulation has likely contributed to the difficulty of selling green shipping fuels.
Misleading Logarithmic Scales and the Disregard for Energy Efficiency
A chart linking low energy consumption with poverty is widely shared on social media. The graphic uses a misleading visualization, and if we look at the data more objectively, it tells a very different story - one that highlights the potential of energy efficiency.
Is there a place for E-Methane in a Climate-Neutral Future?
Methane made from green hydrogen and carbon dioxide can directly replace fossil gas. The company TES wants to produce such e-methane, but critics say: that only works due to stacked subsidies and could delay important transformation steps.
Is Carbon Capture and Storage more expensive than we thought?
A controversy about the Hammerfest LNG plant on the Norwegian island Melkøya raises questions about the affordability of post-combustion carbon capture and storage. Equinor wants to electrify its operations - and said CCS would be too expensive.
Carbon Removal with Demolished Concrete
At a recycling facility on the outskirts of Berlin, carbon emissions from biomethane production are stored in construction waste. The Swiss company Neustark hopes that its technology will play a part in a future carbon removal industry.
BASF starts the World's First Electric Cracker Furnace
Electrifying steam cracking can reduce emissions in the chemical industry, but it does not change the use of fossil input materials. It is only a first step towards climate-neutral chemicals.
What we do not know about Planet-Warming Hydrogen Emissions
In the atmosphere, hydrogen acts as an indirect greenhouse gas. Recent studies show that its warming potential is higher than previously thought, causing concerns about a much wider use of hydrogen in the future. Yet, very little is known about hydrogen leakage rates.
E-Fuels and E-Chemicals may need multiple times the World's current Electricity Production
Technologies turning water and carbon dioxide into energy-rich chemicals could replace fossil fuels where electrification is not feasible. However, Carbon Capture and Utilization (CCU) would require enormous amounts of clean electricity.
Unburning CO₂: The Problem with Fossil Carbon Capture and Utilization
Technologies that turn carbon dioxide into fuels or chemical resources can play a role in a climate-neutral future. But they come with challenges and usually only delay emissions. This can lead to overestimating their potential.
The Trouble with European Green Electricity Certificates
Electricity companies from Iceland and Norway sell green electricity certificates (Guarantees of Origin) while their customers advertise using the same renewable energy. After a temporary ban on certificate exports from Iceland, the responsible Association of Issuing Bodies (AIB) has permanently lifted that ban and does not plan any further action.
Insecure Password allowed Administrative Access to Electric Vehicle Chargers
Electric vehicle chargers of the brand Hypercharger were shipped with an insecure default password and allowed access to a configuration interface to anyone over the Internet. The vendor reacted quickly, but incidents like this show potential IT security risks of electrification infrastructure.
Should we burn Methanol when the Wind does not blow?
Electricity grids with high shares of wind and solar energy will require energy storage over long periods of time. A new study suggests that green methanol might be more attractive than hydrogen in some cases.
Making Glass without Fossil Gas
Today, glass production uses primarily fossil fuels and comes with substantial carbon emissions. Electrification could change that, but it probably cannot be scaled enough to power large production facilities completely. And even a glass industry powered by renewable energy would have remaining CO₂ emissions.
The avoidable Super-Greenhouse-Gas from Fertilizer, Nylon, and Vitamin B3 production
The production of some nitrogen-based chemicals can cause substantial nitrous oxide emissions (N₂O), a potent greenhouse gas. Technology to stop these emissions is cheap and readily available, but it is not always applied.
How to make Plastics without Fossil Fuels
Decarbonizing plastics and other petrochemical processes requires more than clean energy; it requires different input materials. A technology used in China's coal-based chemical industry could be an interesting building block for the future of plastics.
EU Innovation Fund: Oxyfuel CCS, E-Methanol, and more
The EU Innovation Fund is one of the most important funding instruments for large-scale and industrial decarbonization projects. We look at the latest funding round: Multiple oxyfuel CCS projects for cement production, lots of e-methanol – and not much electrification.
Can CCS Escape from its Fossil Fuel Industry Roots?
Carbon capture and storage could help stop carbon dioxide emissions that are otherwise hard to avoid. But the technology is surrounded by controversies and is closely tied to the fossil fuel industry.
Cement's future could be a combination of Carbon Capture and Electrification
Cement is an industry where capturing carbon emissions may be necessary. A combination with process heat electrification could be better than CCS alone.
Double Counting and other problems with Green Electricity Certificates
Double counting of green energy had recently led to a suspension of renewable electricity certificates from Iceland. Now they can be exported again – even though the problems are not solved. But that is not the only problem with renewable electricity certificates.
Hotter Heat Pumps could help Electrify Industrial Heat
Most energy in industry is used to provide heat. The most efficient way to decarbonize heat is to use heat pumps powered by green electricity. Which leads to the question: What temperatures can they achieve?
How Iceland sold the same Green Electricity twice
European renewable energy certificate led to double counting of the same electricity from Iceland. Certificate exports have now been suspended. But the problem is not restricted to Iceland.
Hype and E-Fuels: The Haru Oni pilot plant
Making fuel just from wind, water, and air – that's the promise of the Haru Oni project in Chile. But claims by the companies operating the plant contain a lot of hype.
Making Steel with Electricity
The Siderwin research project tested a new method of steelmaking that uses direct electrolysis of iron oxide in a pilot plant in France. The steelmaker ArcelorMittal now announced that it wants to commercialize the technology.
Do Ammonia Crackers make sense?
Several companies have announced plans to build ammonia crackers to use ammonia as a hydrogen carrier. However, do they make sense as long as existing ammonia facilities run on fossil-based hydrogen?
Gas Stoves and Gas Grids
Cooking with gas represents only a tiny fraction of overall gas use. Some say it does not matter much for the climate, but is that true?
The Future Dominance of Solar and Wind Energy
There is surprisingly strong agreement in future energy scenarios about the dominance of solar and wind energy.
Hydrogen Heating and the Future of the Gas Grid
Most experts don't see a future for hydrogen boilers in buildings, but industry groups lobby for them. This raises an important question: What future is there for gas grids?
The path to Green Steel could be Hydrogen
Several steelmakers are investing in technologies that could clean up one of the biggest contributors to climate change.
