Batteries and biofuels lead the way

AeroTime is excited to welcome Michael Barnard as our columnist. Michael spends his time projecting scenarios for decarbonization 40-80 years into the future, and assisting executives, Boards and investors to pick wisely today. Whether it’s refueling aviation, grid storage, vehicle-to-grid, or hydrogen demand, his work is based on fundamentals of physics, economics and human nature, and informed by the decarbonization requirements and innovations of multiple domains. The views and opinions expressed in this column are solely those of the author and do not necessarily reflect the official policy or position of AeroTime.

For twenty years or more, electrifying everything has been at the top of climate change action plans. Mark Z. Jacobson’s 100% Renewables by 2050 modeling has spelled out the climate, air quality and economic advantages globally. Thought leaders including Saul Griffith, Hans-Josef Fell, Fatih Birol, and Mark Diesendorf from have been focused on this key solution as well.

It’s at the top of my Short List of Climate Actions That Will Work As Well. And it’s true across the transportation segment as well. All ground transportation — except for tiny niches like vintage cars — will be grid tied or battery electric. Bulk shipping will plummet with peak fossil fuel demand and batteries will power all inland and most short sea shipping, and biodiesel will power the rest.
