Hydrogen

By Tom Konrad, Ph.D., CFA You don’t have to own mining companies to benefit from rising metals prices. This is a roundup of first quarter earnings notes shared with my Patreon supporters over the last week. Waste to energy operator Covanta and specialty metals recycler Umicore are both benefiting from skyrocketing metals prices. Just as renewable energy and energy efficiency stocks have long shown that investors don’t have to own fossil fuel companies to benefit from rising prices of fossil fuels, recyclers like Covanta and Umicore are showing that you don’t have to own environmentally damaging mining companies to benefit from rising...

by Jim Lane Wandering the halls at the BIO World Congress and later to be seen again at ABLC NEXT this November, we ran across one of the most interesting technologies relating to ethanol production and markets we have seen in a month of Sundays, perhaps two months’ worth. The problem First, let’s revisit the problem. There’s simply too much ethanol being produced for the markets to absorb, given the Trump Administration’s massive cutbacks in US ethanol targets —In the resulting massively oversupplied market, the inevitable has happened, ethanol producers, growers and the Midwestern economies are being crushed. And they thought they...

I don’t suppose that anyone actually dreams of hydrogen, but in the bio-economy there just isn’t quite enough of it and we read about it and sometimes think about it so much that we might as well be dreaming about it. For those newer to the field, one of the problems of using biomass to make a fuel is that a carbohydrate contains around 53% oxygen by weight and needs about 16% more hydrogen that it contains to make a hydrocarbon fuel. That’s one of the reasons that biofuels are often esters (such as biodiesel) or alcohols (such as ethanol),...

The first article in this series introduced the two prominent types of hydrogen fuel cells - alkaline fuel cells (ALKFCs) and proton-exchange membrane fuel cells (PEMFCs). Fuel cells are devices that convert stored hydrogen into usable energy, and constitute an essential part of the hydrogen economy. Subsequent articles shall focus on various characteristics of these two cells.  The graph above shows the power costs ($/kW) of PEMFCs and ALKFCs as the technology has advanced over time. In other words, they show the initial capital cost for every 1 kW of fuel cell  capacity (note that this axis is in the...
