“…In addition, today, mathematical models describing photobioreactors' operation already exist and provide the opportunity to predict their productivity in relation to external factors (CO 2 concentration, illumination, etc.) [65][66][67]. In prospect, this technology can be used, for example, in a large slow-moving robotic ship or barge that serves as a fuel source for a number of small autonomous mobile robots as shown in Figure 2.…”

This paper presents the problem of application of modern developments in the field of bio-energy for the development of autonomous mobile robots' power sources. We carried out analysis of biofuel cells, gasification and pyrolysis of biomass. Nowadays, very few technologies in the bioenergy field are conducted with regards to the demands brought by robotics. At the same time, a number of technologies, such as biofuel cells, have now already come into use as a power supply for experimental autonomous mobile robots. The general directions for research that may help to increase the efficiency of power energy sources described in the article, in case of their use in robotics, are also presented.

“…At present, around 90% of the global algae production is conducted in the open systems [14][15]. Estimates indicate that the global annual production of microalgal biomass is equal to 15,000 tonnes of dry mass with the market value in the range from 30 to 300 euro per kilo [16].…”

“…Bubble column and airlift photobioreactor designs, as well as others, such as fermenter, flat panel and spiral tube designs are more complex than the open equivalents, and the cultivations realized in them are considered as much more cost-intensive [9,16]. Such a cost is associated with the necessity of gaining sufficient space inside the room for installations, higher energy consumption, need of medium sterilization and the necessary service cost conducted by staff with adequate skills and qualifications.…”

“…The intensive development of algae biotechnology is aimed at the improvement of largescale algae production in cost-intensive closed cultivation systems. In connection with this, the studies conducted nowadays focus primarily on the search for more and more effective microorganism strains, their genetic modifications, optimization of the design and the operation of various reactor types in order to ensure the high productivity of algal biomass [16,23]. Apart from this, activities are undertaken with the aim of reducing the high cost associated with the investment and fluid pumping, light demand, cooling, draining and drying of biomass in such a manner that the resulting system could be competitive in relation to the open systems, which have a predominant share in the market.…”

Abstract. This paper undertakes the description and assessment of various solutions applied for the design of photobioreactors as the type of apparatus, which can provide high output of green algae biomass. The design of such apparatus plays an important role in the context of the concurrent fulfillment of ecological and economic requirements, which are necessary to conduct an efficient and effective technology using cheap and easily accessible resources to produce different goods. Nowadays, algae is seen as one of the most promising sustainable way to produce energy in the future (biofuels, electricity, thermal energy) but technologies of biomass production and processing are still under development particularly to increase biomass and energy output. The cultivation costs in closed systems are still high, limiting their commercial applications to high-valued compounds but they can be reduced by efficient bioreactor designs, which are able to achieve high areal biomass productivities. This paper focuses on the advantages and drawbacks associated with the application of the particular types of bioreactors in algae production, description of their operation parameters and area for practical application, pointing of the constructions (tubular, flat panel, bubble column) that can contribute to improvement the profitability of large-scale production.

“…Therefore, the oxygen needs to be removed and for this purpose a degasser is part of any tubular photobioreactor. Such a degasser can be a vertical bubble column where air, or an air/carbon dioxide mixture is injected [12]. The bubble column results in a dark volume where no nett growth takes place.…”
