Filings - the current landscape
IP Australia has recently released its patent analysis of low
emission technologies (LET), based on patent
filings for the period 2015 - 2020 (see report here). The data serves to 'identify
holdings of specific expertise, helping to analyse the potential
for further specialisation and investment in the
future'.
Patent filings between 2015 and 2018 trended upwards for all
areas of LET that were under analysis (carbon capture and storage,
grid energy storage, solar photovoltaic technology, soil carbon
measurements and low emission steel, aluminium and iron ore).
Globally, over 50,000 applications were filed since 2015 for
carbon capture and storage, grid energy storage and solar
photovoltaic technology respectively. This aligns with what can be
seen commercially, with large-scale projects that will use these
types of technology emerging. For example, Exxonmobil is currently
evaluating the potential for a carbon capture and storage
