Algae Systems Plant Produces Clean Water, Energy

Algae SystemsAlgae Systems says it has demonstrated of a biofuel production approach, which converts algae and wastewater to energy and clean water, with Japan’s IHI Corporation.

A demonstration plant, located in Daphne, Ala., combines wastewater with algae to produce the energy-generating wastewater treatment process, using carbon-negative technologies. This process will yield both bio-fuel and drinking water.

While algae is a component in a number of experimental production strategies, Algae Systems says this approach will differ by using a system that can apply a variety of algae types to production, adding value by treating wastewater, and producing a drop-in fuel using hydrothermal liquefaction to produce fuels that do not need to be blended.

The use of offshore photobioreactors means that a land footprint would not be required to deploy the system commercially, and the motion of waves and wind provides temperature and mixing controls as well as a reduction of operating costs, the company says. It can also eliminate ecological dead zones.

The company says this demonstration plant will be the first of its kind to create a carbon negative fuel by treating wastewater.

Earlier this month algae companies ready to bring their carbon capture and utilization efforts to the marketplace asked the EPA to support the technology as a viable alternative to carbon capture and sequestration in its carbon pollution regulations.
