Developments of five selected microalgae companies developing 'closed' bioreactor biofuel production systems

摘要: This work reviews the current status of five selected companies at forefront production liquid fuels from microalgae produced in 'closed' photobioreactors and fermenters: Algae.Tec, Algenol Biofuel, Heliae, Solazyme Solix. All review have developed novel closed systems, each with unique technology partners, capabilities commercial strategies. Advantages reactors include higher volumetric productivity reduced contamination risks. Conversely, largest challenges for are minimising capital costs, addition to attracting initial investment non–conventional complex technical systems. provides a concise summary company's technology, background, where available, qualified assessment economics their demonstrates that commercially viable systems will need achieve sustained reduce per unit industry cross–collaboration be essential system developments successfully produce cost–competitive fuels.
