A trail of new methods of harvesting seaweeds is expected to begin in Connemara in few weeks. Two boats are being brought for this purpose from Canada by the company Ascidian Sea Plants in order to show the harvesting methods used in Nova Scotia. The trial will be conducted in ArramaraTeoranta seaweed industry, which has […]

Researchers from China performed an experiment to analyse the mechanism of alkaline flocculation harvesting process and the difference between the two strains of algae Chaetoceros muelleri (marine diatom) and Scenedesmus quadricauda (freshwater algae). Alkaline flocculation of C. muelleri resulted in increase in particle size with increasing pH, increase in absolute value of zeta potential and […]

Maryland based start-up Manta Biofuel has received USD 150,000 of investment from Chesapeake Bay Seed Capital Fund to develop next-generation prototype of its portable, solar-powered floating algae harvester. The company’s harvester autonomously navigates through water and collects algae which is converted into crude oil through a process called hydrothermal liquefaction.  It is expected that Manta […]

Researchers from USA conducted an experiment to harvest microalgae using phase separation of thermoresponsive polymers and copolymers of N-isopropylacrylamide and allylamine.  Chlorella protothecoides was taken as an experimental model to perform the experiment. The results showed that Chlorella protothecoides cells were separated from the solution containing mixture of algae and polymers when it was heated […]

The Super Formula to Fight Aging – Its Name is Astaxanthin -Know more Oilgae comprehensive report has been designed for entrepreneurs and investors keen […]

One of the biggest problems in algae biofuels commercialization lies in the process of algae harvesting and extraction which requires large external energy inputs. Some of the attributes of algae which makes algae harvesting and extraction difficult include: 1. Algae cells are very small in size (about 2 to about 20 nm) 2. Algae oil […]

OriginOil and Algasol Renewables, two major companies in the algae energy industry have entered into an agreement for developing an integrated algae growth and harvesting system. Algasol, which is already working with NASA and Lawrence Berkeley National Laboratories plans to bundle its offerings with OriginOil’s Algae Appliance, developed by the company wit the aim of reducing the […]

Researchers at the University of Sheffield have developed a technology based on microbubbles, to improve the way of algae cultivation, which eventually will make the algae harvesting cheaper and easier. Professor Will Zimmerman and his team have devised an inexpensive way of producing microbubbles that can float algae particles to the surface of the water. […]

A new algae harvesting system called Algae Appliance by OriginOil Inc. This appliance would process at a low cost in addition to minimal use of chemicals. OriginOil has slated 2012 for the commercial release of Algae Appliance. The system is slated to remove up to 90% of the initial water volume. The system is designed […]

Harvesting microalgae is difficult as well as energy intensive. This is mainly because the most rapidly growing algal species are frequently very small and often motile unicells which are the most difficult to harvest. Moreover, the conventional harvesting methods used for harvesting microalgae – such as centrifuges, filtration and flotation equipments – are energy-intensive. A […]

Biodiesel using genetically engineered algae has been tested from some years but so far has not proven to be practical on an industrial scale. The Joule Unlimited process uses another cyanobacterium that it claims to be able to manufacture 15,000 gallons of diesel fuel per acre at about $30 a barrel, using very little biomass […]

Diversified Technologies, Inc. has introduced a low-cost process for the pre-treatment of algae using pulsed electric field, or PEF, technology to streamline the extraction of oils from algal cells early in the biorefining process. The Diversified Technologies’ PEF Pre-Treatment of Algae for Oil Extraction Process applies 10-30 kV/cm electric pulses for 2 to 20 microseconds […]

Algae fuels commercialization faces challenges in every part of the value chain. Starting from strain selection to product extraction there are biological  and engineering breakthroughs which are required to make algae fuels a reality. With respect to harvesting, the main issue is the energy required to remove the algae cells from the liquid media. A company by […]

Dr. John Benemann, one of the authors of a seminal U.S. National Renewable Energy Laboratory report from 1998 on biofuel from algae and an internationally-recognized bioenergy expert said he thinks LiveFuels is “in as good of shape as anybody” to make its R&D happen. Morgenthaler-Jones said LiveFuels has been taking […]

Recently two interesting pilot programs seems to improve the commercial viability of algae bio-fuel :The first was the grant from the California Energy Commission to use the nano-metals as catalysts for generating bio-fuel from algae. The company called QuantumSphere will be developing a nanocatalyst-based bio-gasification process for taking wet algae […]

One can grow algae but it doesn’t mean its free.Although algae is believed to be one of the chief feedstocks for biodiesel, growing large amounts of algae and then converting the single-celled creatures remains expensive. Algae biofuel startup Solix, for instance, can produce biofuel from algae right now, but it […]
