SUSTAINABLE HYDROGEN ENERGY PROJECT -- SHEP

 

SUSTAINABLE HYDROGEN ENERGY PROJECT -- SHEP


The Sparhawk Mill is a four story brick building in Yarmouth, Maine
which sits on the eastern bank of the Royal River (historically known
as the Royall River). A dam spans the river just above the mill and
provides low-head water to three 1984 Hydrolec turbines in the
sub-basement, one of which is variable up to 90kW; the other two are
fixed at 90kW. Presently the site generates around 900,000 kWh per year
but slows to a nearly complete halt in July and August. It runs at
irregular rates at other times throughout the year.



Based at the Sparhawk Mill and still in the conceptual stages, SHEP is
a plan to make hydrogen (H2) from the dam's hydro-electric power and
from off-peak renewable and standard power supplied through the power
grid. The making of H2 is accomplished by device called an electrolyzer
which yields H2 and oxygen (O2) from water and electricity. The H2 and
O2 will be stored on-site. We then plan to make electricity for the
newly renovated office complex in the mill and also for on-peak sales
of electricity to the grid. Producing electricity from H2 is
accomplished by a device called a fuel cell with water and heat as
by-products. Both processes, making H2 and O2 from electricity & water
and making electricity from H2 will each give off extra heat. We plan
to use this waste heat to supply heat and cooling for the office
complex. Finally, we plan to sell gaseous O2 for medical use and
gaseous H2 for transportation and other industrial uses. We will also
use a small amount of the H2 made at SHEP for public demonstrations of
hydrogen as an energy carrier. We view this project as a technology
incubator which may attract funding and participation from a variety of
sources, including regional educational institutions, government,
foundations, corporations, and individuals.



The Hydrogen Energy Center expects that, through SHEP, we can show how
hydrogen, made from a mix of renewable (some delivered through the
grid, some made from hydro on-site) and standard off-peak power,
provides an environmentally positive step toward clean energy for an
evolving power infrastructure. Using power from the dam and from other
"green" sources delivered through the grid, we plan to provide a
constant power source by using an electroyzer, hydrogen storage, and
fuel cells to re-generate electricity from the stored hydrogen, all on
site.



In the Sparhawk Mill, we are fortunate to have an interested and
knowledgeable future landlord who wants very much to see this project
work. It remains to be seen if the project can turn a profit by selling
on-peak electric power, hydronic heat, hydrogen and oxygen while
meeting operating expenses such as: buying off-peak electric power,
rental of space, costs of operating and maintaining the facility. It is
expected that in this initial demonstration project, we will operate at
a loss. We hope that information gleaned from this project and an
evolving market for hydrogen will show potential for and point the way
to sustainable profit.

lkgeo1 why don't you digest all these postings and limit
yourself to one post a week with just the topic and a
link pointing to the press release. This will reduce the
amount of ridicule you receive and will make your postings
look less like spam.
