A new study published in the journal ‘Nature Energy’ shows that in 2023, less than ten percent of the originally announced green hydrogen production was realised. The main reason: hydrogen remains an expensive good for which there is little willingness to pay.
Adrian Odenweller and Falko Ueckerdt from the Potsdam Institute for Climate Impact Research (PIK) determine this competitiveness gap for all 1232 globally announced hydrogen projects. They advocate for a robust political strategy that is based on realistic expectations for hydrogen and closes the implementation gap.
In this video Adrian Odenweller presents the study and its findings.

Industrial microbes could feed cattle, pigs and chicken with less damage to the environment: Deforestation, greenhouse gas emissions, biodiversity loss, nitrogen pollution – today’s agricultural feed cultivation for cattle, pigs and chicken comes with tremendous impacts for the environment and climate. Cultivating feed in industrial facilities instead of on croplands might help to alleviate the critical implications in the agricultural food supply chain. Protein-rich microbes, produced in large-scale industrial facilities, are likely to increasingly replace traditional crop-based feed. A new study now published in the journal Environmental Science & Technology for the first time estimates the economic and environmental potential of feeding microbial protein to pigs, cattle and chicken on a global scale. The researchers find that by replacing only 2 percent of livestock feed by protein-rich microbes, more than 5 percent of agricultural greenhouse gas emissions, global cropland area and global nitrogen losses could each be decreased.
