Batteries are making their way into more passenger cars and commercial vehicles than ever before, but the limits of electrification mean that we’ll likely need alternative fuels to decarbonize heavy transport like ships, planes, and trucks. 

So what are those fuels and what modes of transport do they suit best?

In this episode, Shayle talks to his colleague Andy Lubershane, partner and head of research at Energy Impact Partners. They talk through the limits of electrification and the alternatives for decarbonizing trucks, ships, and planes, drawing on Andy’s recent blog post, “How will we move the big, heavy things?”. They cover topics like:

• The main limitations of batteries: density and infrastructure
• Volumetric and gravimetric density, and why they matter for different types of vehicles
• How fossil fuels would beat out even a theoretical “uber-battery” multiple times denser than current batteries
• Why upgrading “always-on” grid infrastructure can be lengthy, expensive, and disruptive 
• The alternatives to electrification: biofuels, hydrogen, and e-fuels
• The advantages and limitations of each for different modes of transport
