Dear Mr. Pettman,
I am presuming that you are using bio-digesters for methane/CO2 production?
These are typically permanent installations due to the volumetric amounts
necessary for any serious production rate. The "sludge" does need dewatering to
be useful and over long periods of time, causes serious damage to the soil
which has created a set of US EPA regulations for it's use in the US.
Although wood is a biomass, it does not degrade in these units well and in
devastated Puerto Rico areas, I am sure that much of the waste is woody
buildings and so on which should be used in thermal conversion systems for
power generation, but the technology hasn't advanced far enough to address the
problem in real economic terms. Plastics are likewise better processed through
thermal systems.
I have seen useful 2 megawatt dairy biomass digesters in Wisconsin, the
company had 60 of them installed and used standard IC spark ignited engines for
operation, plus very low cost, simple design and operation.

Our Help
Greetings EVERYONE.
Biomass is a massively underused resource.
Our company has bio generators from which we are able to make electricity and
produce agricultural grade water - which can be turned in potable water - and
we use the gestate for fertilizer.

Tom and lists:
This is to offer a little support to HOMER and Peter Lilienthal, who I have
known for maybe 25-30 years. We both were at NREL (National Renewable Energy
Laboratory - and/or its predecessor SERI), where HOMER was developed as an
optimization system for micro-grids. Peter left long ago and is now up the
road in Boulder - see https://www.homerenergy.com/.
The surprise to me is the large amount on biomass at the above site - which I
had not seen before (and have been encouraging). On this page you only see the
word solar - but there is more.

Some have asked what is being done for energy and fuel in Puerto Rico. Here’s
an appeal from Homer Energy which specializes in small scale ppower generation
and distribution.
Tom
Many of you in the microgrid industry have asked me what we can do to help
Puerto Ricans get the lights back on quickly, and cleanly.
Seven weeks after Hurricane Maria wiped out 100% of the ailing power grid, 70%
of Puerto Ricans still do not have electricity, and many expect it will take a
full year to restore the whole island.
We all know that solar + storage microgrids can be installed much faster than
rebuilding the obsolete, centralized grid that had been powering the island,
and that these systems could be much more resilient to future hurricanes and
fuel disruptions while bringing economic benefits to Puerto Ricans.
Help Puerto Ricans Now…
We have found five non-profit organizations that are on the ground in Puerto
Rico today, bringing microgrids to the places that need it most. We have
vetted these organizations and, if you want to get the lights on for Puerto
Ricans before the end of the year, they will make good use of your money or
equipment.
Empowered by Light - FUND Solar+Storage+ Clean Water for Fire Stations
Empowered by Light is installing solar + storage on fire stations in
communities that will otherwise be without power of any kind for many months.
These systems power critical loads and enable the stations to better serve as
community centers in the aftermath of Hurricane Maria. They are also deploying
water desalination and purification systems that produce 250 gallons of water
daily--enough to provide essential drinking water to over 500 people.
Good360 - FUND Solar for Schools and Community Centers
Good360 specializes in efficiently distributing critically needed product
throughout the entire cycle of disaster impacted regions around the world.
Needed product in Puerto Rico includes solar products, water filters, and all
types of cleaning and rebuilding materials. Puerto Rico partners so far
include Salvation Army, Crisis Response International, Ninos De Nueva, and St.
Vincent De Paul.
Solar Puerto Rico - FUND Off-grid Solar Kits
PJ Wilson, the founder of Renew Missouri(LINKED), is in Puerto Rico
distributing small off-grid solar kits, consisting of solar panels, batteries,
and LED lights. His goal is to distribute 150 of these systems in the next two
weeks.
Resilient Power Puerto Rico - FUND Solar Generators
Resilient Power Puerto Rico was launched in the hours following Hurricane
Maria's devastating strike on the island of Puerto Rico. Resilient Power Puerto
Rico starts with nimble, targeted efforts to deliver solar generators to the
most under-served areas of Puerto Rico as a relief measure to get communities
powered up and back in contact, with a planned evolution into long-term
disaster-preparedness and clean-energy solutions to impact the entire island.
Solar Saves Lives - DONATE Product or Money for Solar+Storage
Solar Saves Lives is a new initiative to coordinate shipments of urgently
needed solar and battery storage equipment to Puerto Rico and the U.S. Virgin
Islands. We are seeking both product donations from the solar industry, and
monetary contributions that will go directly to the relief effort. Solar Saves
Lives is led by The Solar Foundation in partnership with the Clinton
Foundation, Operation Blessing, Direct Relief, and J/P HRO.
The Longer Term…
Here at HOMER Energy we are continuing to explore how best to catalyze the
construction of solar power systems on schools, clinics, community centers, and
ultimately homes and entire communities in Puerto Rico; however, the immediate
priority is to get small-scale equipment into powerless communities as quickly
as possible. Alison Mason is the solar/storage expert on our team who is
spearheading our effort. She will be in Puerto Rico next week providing first
hand oversight of these efforts.
We believe that small-scale solar + storage systems can reduce disease, save
lives, and help many parts of Puerto Rico. This effort does not replace the
need to restore conventional electric service, but will be able to reach many
desperate communities much faster. If you would like to help, please direct
your contributions to the five organizations listed above.
If you know of other organizations working with solar in Puerto Rico, send us
an email at [email protected].
Sincerely,
Peter Lilienthal
