Graphite Developers Eye Large Growing Market
The post “Integrated Graphene Producers” featured several graphene producers with novel business models that marry captive graphite sources to the technology and knowhow to produce graphene. These are not the only graphite producers. Although not as elegant as graphene with its svelte single-atom profile, the market for graphite has its appeal as well. Graphite has been a staple in steel industry crucibles, foundry molds and automobile brake linings. These days graphite has moved into another even more important place in cars - lithium ion batteries that make electric vehicles viable as replacements for gas guzzling cars and trucks.
Spherical graphite is especially desirable because the graphite anodes hold...

Vertical Integration In Graphite Industry
by Debra Fiakas, CFA
Grand View Research, another industry research group, estimates that the graphite market could reach $93 billion by 2025, boosted mostly by new demand for electric vehicle batteries as well as batteries for electronic devices and grid-storage systems. According to Technavio, an industry research firm, the graphite industry is estimated to grow more than 5% annually through 2025, largely on new demand for highly purified graphite material used in lithium ion battery anodes.
Among the immediate beneficiaries of this growth trend are the established graphite producers and those among the most recent entrants that have begun ringing up sales...

In Search Of Solid State Battery Stocks
by Debra Fiakas, CFA
Greater energy density or the amount of energy stored is the mission of every battery developer. The higher the energy density, the longer a battery can serve its owner. Scientists have been adjusting circulating chemistry, cloaking electrodes in exotic metals, and otherwise tinkering with conventional battery designs. Debate even spills over into the raw material supply chain as it has recently over the use of expensive and sometimes difficult to source cobalt as an additive to lithium ion battery designs. Others are trying to tame silicon for use in battery anodes.
Perhaps the most daring developers have abandoned conventional battery design...

Water Stocks in the Americas
by Debra Fiakas, CFA
The post “Water: Invisible Crisis” introduced a new series on water supply in Latin America, describing the lack of access to quality water despite a bountiful supply of rainfall and snow melt. As the series has unfolded we have learned that water supply in Latin America is largely a local government undertaking. Investment opportunities are limited to water management companies that sign on to operate government-owned infrastructure or water treatment solution providers.
Water supply to the north has inched further into the commercial realm. A discussion of water investment would not be completed without a look at private water suppliers in the...
List of Synthetic Fuel and Drop-in Biofuel Stocks
Synthetic fuel stocks are publicly traded companies creating transportation fuel from non-liquid feedstocks such as natural gas, coal, and municipal waste. Drop-in biofuel stocks are publicly traded companies creating transportation fuel from organic feedstock that can be used, transported, and stored by conventional petrofuel infrastructure. A synthetic fuel is a biofuel if it is made from organic feedstock. It is a drop-in fuel if it is compatible with the existing infrastructure for petroleum based fuels.
