“…To identify the structure of the reaction products, the main products were purified by TLC on silica gel plates (20Â 20 cm, GF254, Qingdao Marine Chemical Factory), then analysed using negative ion electrospray ionization mass spectrometry (ESI-MS), 1 H-NMR, 13 C-NMR and 2D 1 H-1 H COSY NMR spectroscopy, as described previously (23,24).…”

“…Alginate, an acidic heteropolysaccharide, consists of b-D-mannuronate (M) and a-L-guluronate (G), which arrange into polyM, polyG, and heteropolymeric random polyMG blocks (1). Alginate is the most abundant carbohydrate in brown algae and commercially useful due to its high viscosity and gelling property.…”

“…The floating array used buoys or fenders connected to the array for flotation. Aizawa et al (2007) envision, but have not developed or tested, a facility located in coastal waters shallower than 500 meters and offshore in water depths between 500-3,000 meters. Offshore "sea kites" would be used 1.5 km length by 1 km width.…”

“…Depending on the species cultivated and attachment method used, harvest may involve mowing (leaving the growth structure in place) or recovery of algae and the growth substrate for separation on land (Ugarte and Sharp, 2001). Harvesting would likely require developing a reaping vessel (Aizawa et al, 2007), although vessels equipped with A-frames such as trawling or long-line fishing vessels could possibly be adapted to recover algae and growth substrates.…”

The DOE-OBP Multi-year Program Plan (MYPP) biomass production targets are 44 million dry tons per year by 2012 and 155 million dry tons per year by 2017 (EERE Biomass Program, 2011). Macroalgae, more commonly known as seaweed, could be a significant biomass resource for the production of biofuels. The overall project objective is to conduct a strategic analysis to assess the state of macroalgae as a feedstock for biofuels production. To this end, this project provides an assessment of the potential for domestic macroalgae production and identifies the key technical issues associated with the feasibility of using macroalgae resources. Work began in FY10 as a screening analysis of the key questions related to the status of macroalgae as a feedstock resource. These efforts addressed the state of technology, types of fuels possible, a rough order-of-magnitude resource assessment, and preliminary high-level economic analysis, resulting in a Summary Report entitled Macroalgae as a Biomass Feedstock: A Preliminary Analysis (PNNL-19944).While considerable progress has been made in developing and applying GIS-based spatiotemporal models of high granularity to siting microalgal growth facilities in terrestrial landscapes in the continental U.S. (Wigmosta et al., 2011), parallel efforts to identify suitable sites for macroalgal cultivation in U.S. marine waters have yet to be reported. Such effort requires development of new analysis tools because those developed for land-based microalgal resources (Wigmosta et al., 2011) are not directly applicable to marine waters. Thus, the plan for subsequent years, starting in FY11, was to develop a multi-year systematic national assessment to evaluate the U.S. potential for macroalgae production using a GISbased assessment tool and biophysical growth model developed as part of these activities. The broad goal of this modeling effort is to develop a National Macroalgae Assessment Model for evaluating macroalgae production in marine waters within the U.S. Exclusive Economic Zone (EEZ). Focus was placed on an assessment of kelp, a group of brown macroalgae considered suitable for conversion to biofuels based on biochemical composition and growth characteristics. Progress in FY11, which focused on model development and initial application of the models to demonstration areas in offshore waters, is described in this report.During FY11, a concept map describing spatial models to identify suitable sites for producing macroalgae biomass was developed as a framework for conducting a GIS-based national resource assessment within the U.S. EEZ. The spatial models included modeling macroalgae production potential, constrained by competing uses and legal, environmental, and infrastructure considerations at specified locations in the U.S. EEZ. A literature review of these constraints was conducted, and remotely-sensed data sources were identified, downloaded, and processed using 8-day composites from 2000 to 2011 to support site screening and macroalgae growth model development.

“…The concept of combining bioenergy with carbon capture and storage (BECCS) has been identified as one mechanism to achieve energy production with a net negative atmospheric carbon emission (Hughes et al 2012). The Ocean Sunrise Project in Japan has been developed with aims to combat global warming through seaweed bioethanol production by contributing an alternative energy to fossil fuel (Aizawa et al 2007). Co-culturing macroalgae with industry flue-gas provides a holistic solution for carbon sequestration by recycling carbon and converting the biomass into a range of bioenergy products from biogas to liquid and solid biofuels (Cole et al 2014).…”

Carbon dioxide mitigation potential of seaweed aquaculture beds (SABs)

Seaweed aquaculture beds (SABs) that support the production of seaweed and their diverse products, cover extensive coastal areas, especially in the Asian-Pacific region, and provide many ecosystem services such as nutrient removal and CO 2 assimilation. The use of SABs in potential carbon dioxide (CO 2 ) mitigation efforts has been proposed with commercial seaweed production in China, India, Indonesia, Japan, Malaysia, Philippines, Republic of Korea, Thailand, and Vietnam, and is at a nascent stage in Australia and New Zealand. We attempted to consider the total annual potential of SABs to drawdown and fix anthropogenic CO 2 . In the last decade, seaweed production has increased tremendously in the Asian-Pacific region. In 2014, the total annual production of Asian-Pacific SABs surpassed 2.61 × 10 6 t dw. Total carbon accumulated annually was more than 0.78 × 10 6 t y −1 , equivalent to over 2.87 × 10 6 t CO 2 y −1 . By increasing the area available for SABs, biomass production, carbon accumulation, and CO 2 drawdown can be enhanced. The conversion of biomass to biofuel can reduce the use of fossil fuels and provide additional mitigation of CO 2 emissions. Contributions
