Island biogas energy and fertilizer – Dr. Antoine N’Yeurt of the University of the South Pacific USP, PODenergy, CHP Energy, and other researchers and equipment companies have planned projects in USP member countries. Islands can replace diesel, propane, wood from mangroves, and artificial fertilizers by harnessing and increasing biogas production by: 1) Producing electricity instead of flaring at existing wastewater operations; 2) Using distributed anaerobic digesters to produce cooking gas; 3) Harvesting nuisance seaweed for biogas; 4) Growing algae for nutrient remediation, biogas, and fertilizer.

This proposal presents a combination of technologies that can lead some islands toward energy self-sufficiency, while also boosting local food production.  If the island has sufficient area of sheltered bays relative to its population, as does Fiji and some other Pacific Islands, it can produce enough biogas to eliminate the need to import diesel or bunker fuel for electricity, or propane/butane for cooking gas or heating hot water.  We are also investigating the potential for new hydrothermal technology to produce biocrude oil that could be refined to produce transportation fuels.

In addition our technologies produce fertilizers to increase food production, and clean up bays polluted by sewage discharges or agricultural runoff, restoring them to productive fisheries.

Innovations in Phase 1 include:

1)    Arranging Power Purchase Agreements (PPAs) for biogas-fueled electricity from local wastewater treatment plants already using anaerobic digesters.  This is all existing technology, routinely profitable in developed countries.

2)   Expanding existing island expertise with manure digesters to a cooking and lighting gas business which leases small digesters with training and support to residential teams and resorts.  People will harvest nuisance seaweed to increase their biogas supply, which improves indoor air quality while reducing ecosystem impacts, such as mangrove cutting. 

3)   Installing seaweed nutrient remediation/algae growth systems near local wastewater treatment plants to produce a reliable supply of biomass and biogas for larger PPAs.

In addition to the Phase 1 project above, USP and PODenergy have plans using the knowledge and profits from Phase 1 to develop sustainable seaweed grow-harvest-digest methods for larger scale.  For example, 20,000 ha of Fiji’s 40,000 ha of sheltered bays would be sufficient to produce 60 MW of electrical power from seaweed biogas, which would eliminate the need for diesel powered electricity in all of Fiji.

Other benefits from this technology approach involve clearing invasive seaweed from coral reefs two ways.  One approach is to harvest invasive seaweed, produce biogas and fertilizer from the seaweed, and apply income from product sales to offset harvesting costs.  The second approach is to grow algae in floating ponds to remove excess nutrients before those nutrients reach the reef.
