Hydrogen and lithium batteries and their relationship in overland transport with the environment

Mié, 09/30/2020 - 13:10 -- anegrete

An increase in demand and use of land passenger transport has been observed. Its electrification is considered a plus for the environment and the economy. However, there is a debate about whether to take advantage of the lithium present on the ground or to invest in hydrogen production.

What is the best alternative in order to protect the environment and slow down climate change? Hydrogen is the most abundant and lightest element on Earth, but its molecule does not occur naturally in isolation. Lithium, different from H2, can be found in specific deposits. The most important is the "Lithium Triangle".

At present, there is no perfect energy source. Environmentally, the best alternative is H2 from water, which does not generate any pollutant after combustion. Its problem is that it is not yet economically or energetically viable.

The confined energy landscape

The energy outlook is complicated by the drop in demand during confinement, especially for fossil fuels; however, the importance of oil remains crucial. China is the central player for both the global oil industry and the major player in terms of clean energy sources.

Economies such as Colombia, Venezuela, Ecuador and Bolivia are heavily dependent on oil and gas exports; while Mexico and Brazil depend for their tax revenues on the oil companies Pemex and Petrobras.

The panorama shows a dispute between dirty and clean energies in a conjuncture of both energy change and crisis in energy demand. The crisis due to the pandemic may mean a boost to the transition towards cleaner energies under the leadership of China.
