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 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.

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.

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.

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 is an industry where capturing carbon emissions may be necessary. A combination with process heat electrification could be better than CCS alone.

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.

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?

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?

Jan 10 2023

There is surprisingly strong agreement in future energy scenarios about the dominance of solar and wind energy.

Dec 20 2022

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?
