Macroalgae Workshop

ARPA-E held a workshop on "Innovative Approaches to Ocean Cultivation and Processing of Macroalgae for the Production of Fuels and Chemicals" on February 11-12, 2016 in the Washington, D.C. area.  

ARPA-E is interested in identifying critical R&D topics and targets, which need to be addressed to enable a successful transition from today’s macroalgae industry focused primarily on food and specialty chemicals to large-scale fuel and feed opportunities tomorrow.  This workshop brought together experts in macroalgae cultivation, physiology and ecology with those from complimentary fields of plant breeding, oceanography, marine engineering, robotics, and biomass processing, as well as agronomy and the financial community.

Areas of interest for discussion:

Breeding: existing breeding technologies for macroalgae, genomic tools, selection of species for algal cultivation based on suitability for breeding, transferring advanced terrestrial crop breeding tools to macroalgae.

Cultivation and Harvesting: site selection criteria (near-shore, off-shore, deep ocean), site and species specific cultivation system designs, hatchery and seeding technologies, nutrient supply and/or delivery, harvesting equipment, automation/robotics, integration/co-development of cultivation and harvesting systems, synergies with other aquaculture and off-shore energy installations.

Transport, Storage, and Processing:  technologies for dewatering, storage and ensiling, opportunities for off-shore storage & processing, processing/fractionation of macroalgae without freshwater.

Ecosystem Services and Effects: type and scale of potential ecosystem services (e.g. nutrient removal and CO2 sequestration) provided by macroalgae cultivation, impact of large-scale macroalgae cultivation on existing ecosystems and existing marine uses.

Product Opportunities and Commercial Stepping Stones: recognizing that fuels are the most challenging product target, we are interested in product opportunities which can serve as commercial stepping stones and sustain the growth and long-term financial viability of a US-based macroalgae industry on the path to fuel.

We hope that connections made during the workshop may also be helpful in forming creative teams able to propose innovative projects in response to a potential funding opportunity.
