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...

Producing Graphene Materials
Build up of the graphene materials industry has progressed a bit more slowly than originally expected a decade ago as scientists and engineers peered through their electron microscopes at single atoms of carbon and counted their many attributes. At the time the potential to improve performance in end products like metal alloys and electronics seemed limitless. Unfortunately, reality has not imitated early dreams. Those companies that have brought graphene to the commercial market will attest to the challenges of jumping off the laboratory bench and into a factory.
Even more frustrating is the sourcing of graphene to use in research, product development and...

Leading Indian Renewable Energy Stocks
By Ishaan Goel
India is amongst the largest renewable energy markets in the world, ranking third in solar, fourth in wind and fifth in hydro power capacity. Due to its rapidly growing economy, India’s energy needs are constantly on the rise. Moreover, countering air pollution has become one of the government’s top priorities. To achieve this, it has set out the world’s largest expansion plan for renewable energy - a 5x increase of installed capacity to 450 GW by 2030.
The Indian renewable energy market can broadly be divided into two categories - private firms and state-owned enterprises (known as public-sector...

List of Green Investment Advisors
If you want your money to help with the transition to the clean energy economy, most investment advisors will probably try to accommodate by finding a few green mutual funds for you.
There are now hundreds of mutual funds and ETFs that brand themselves as green, but many will not meet your definition of what is "green." This could mean not being completely divested from fossil fuels, investing in nuclear power, or owning too much of non-fossil fuel stocks like Apple (AAPL) and Facebook (FB) and not enough green-focused companies like Tesla (TSLA).
An investment advisor who does not consider values...
Integrated Graphene Producers
Graphene is a one-atom thick sheet of carbon atom arranged in a honeycomb lattice. It is an exceptional conductor of heat and electricity and its strength is unparalleled. Although synthetic graphite can be used to produce graphene and it offers the benefit of consistency, natural graphite is far less expensive as a source material. Synthetic graphite is made by combining petroleum coke with carbon black in a high heat process that burns up profits as it purifies the carbon.
There are several methods for producing graphene. Exfoliation of natural graphite is perhaps the most common alternative because it produces the least defects and leaves...
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...
