What Is Wtw and Ttw?

The term Tank-to-Wheel (TTW) refers to a subrange in the energy chain of a vehicle that extends from the point at which energy is absorbed (charging point; fuel pump) to discharge (being on the move). … The generic term that subsumes Tank-to-Wheel and Well-to-Tank is Well-to-Wheel (WTW).

What is WTW analysis?

Well-to-wheel (WTW) analysis is an application of LCA which is used to compare drivetrains/vehicles from a global perspective. Offer et al., compared BEVs, hydrogen based FCEVs and fuel cell hybrid electric vehicles based on their lifecycle costs.

What are WTT emissions?

A Well-to-Tank emissions factor, also known as upstream or indirect emissions, is an average of all the GHG emissions released into the atmosphere from the production, processing and delivery of a fuel or energy vector.

Well-to-Wheel (in short WtW) is the first step in comparing the efficiency of different solutions towards Greenhouse Gas (GHG) emissions. Those GHG emissions are so crucial to mitigate because simply put, they cause climate change.
