In our surreal world, we continue to subsidize fossil fuels. We rarely subsidize the huge missing link on the way to 100% renewables, which is providing massive amounts of delayed electricity. People misunderstand. They think we do. Uniquely, the IDTechEx report "Future Stationary Energy Storage: Hydrogen, Batteries, Gravity, Gas, Other 2022-2042" looks at all the proliferating needs and technologies on the essential 20-year timescale ahead. It finds that the problems are largely solved of very brief fluctuations previously avoided by the momentum of rotating machines used in fossil fuel plants.

On the face of it, 2021 was a good year for fuel cell electric vehicles (FCEV) in passenger car markets. Toyota, with their second generation Mirai FCEV, and Hyundai, with their NEXO FCEV, both had record sales, which largely made up for Honda announcing in June 2021 that it had decided to pull the plug on production of their Honda Clarity FCV (citing the lack of hydrogen infrastructure and weak demand).

Li-ion batteries are beginning to hit their performance ceiling, especially with regards to energy density. However, a shift in the anode materials used, namely to silicon or lithium-metal anodes, could provide a stepwise improvement to energy density. Their promise can be highlighted by looking at the high number of early-stage companies primarily developing anode materials, most being focussed on silicon, compared to other areas of Li-ion development.
