This data-file tabulates the CO2 emissions from US bioethanol plants, which produce around 1Mbpd of liquid fuels, with an average CO2 intensity of 85kg/boe. In addition, we estimate 160kg/boe of CO2 are emitted in producing US corn, so bio-ethanol has a total CO2 intensity of 245kg/boe (c40% less than conventional oil products).
Our data are based on granular disclosures from 170 separate facilities, which have reported to the EPA and EIA disclosures. Hence we can screen more and less CO2-intensive States and Companies.
Covered companies, ranked by ethanol capacity, include Poet, Valero, Great Plains, Koch, Marathon and White Energy.
This data-file tracks 5,000 patents filed into biofuels: by geography, by company and particularly in 2017-20. The pace of research activity into “biofuels” and “biodiesel” seems to have halved since 2014, suggesting industry interest is waning.
As usual, China has come to dominate the recent patent literature, accounting for 60% of recent filings. Out of the ‘Top 25’ patent filings from 2017-20, 15 are Chinese companies.
Ranked by recent patent filings, technology leaders include Sinopec, BASF, Arkema, Neste, TOTAL, ExxonMobil and DuPont. It is interesting that some well known companies (e.g., Ryze) did not appear to have filed many patents recently. Full details on the patent trends and filings are in the data-file.
