“…Anne, Bugajev, and Koreiviene [7] has conducted a survey in the Curonian Lagoon in Lithuanian as a step to implement microalgae cultivation. Reference [8] has described large-scale microalgae cultivation, while [9][10][11] suggested increasing efficiency with the integration of algae cultivation as a biogas purification Indonesia, as a tropical country and only has two seasons, make plants can photosynthesis, including microalgae, which can flourish because microalgae get enough sunlight, which is 12 h d -1 . In other facts, that 67 % of Indonesia territory is the sea, this opportunity makes microalgae can grow if cultivated in the area around the coast.…”

World consumption of energy is estimated to increase by 49 % from 2007 to 2035, which means averagely 1.4 % yr–1. Many countries in the world began to develop alternative energy that can overcome the resources. Microalgae is one of the renewable energy that has excellent potential for making biodiesel because it contains much oil. Microalgae is the fastest organism in the photosynthesis, so it makes microalgae have high productivity. In this article, researchers use Chlorella sp. because these microalgae contain oil up to 28 % to 32 % from its dry weight, and on the other hand, this type of microalgae is easy to grow and easy to harvest. From the experimental results, the density characteristics of biodiesel Chlorella sp. have values from 0.84 g mL–1 to 0.848 g mL–1, and it is lower than the density of petroleum (diesel), and viscosity value from 2.5 cSt to 3.91 cSt, cetane numbers 51.17 to 53.72 also heating value 44.04 mJ kg–1 and Flashpoint 131 °C. The characteristic result shows that the Chlorella sp. microalgae biodiesel is still in SNI standard (Indonesia National Standard) so that the Chlorella sp. can be used as a substitute diesel fuel.

“…According to this review, gas cleaning with algae is self-sustaining with the addition of minimal nutrients and light, furthermore, it has several advantages over the conventional chemical CO2 reducing methods [14]. Moreover, Salafudin et al [15] combined the water scrubbing and the CO2 binding ability of the plants. Using catfish pond water (which was overgrown with wild algae) as gas purifier, and the measured CO2 capture efficiency of the cleaning system was 50%.…”

Biogas was produced from sheep manure and two types of submerged aquatic plant (Vallisneria spiralis and Egeria densa). The gas cleaning was carried out by a water scrubber, where a significant part of CO2 and H2S can be separated from the gas. A part of water from the scrubber was circulated through an aquatic plant growth tank and the growth of used plants was examined. Addition of E. densa to sheep manure increased gas yield by 8% and the mixing of sheep manure and V. spiralis resulted in 21% increase in gas yield. With the used scrubber, 70-80 vol% methane content can be reached in the cleaned biogas, and the water from the scrubber (which contained dissolved CO2 and H2S) resulted in 56-87% increase in size as opposed to 12-44% increase in the control group.

Summary Depleting fossil fuels and the pollution resulting from their consumption indicate an urgent need for clean and dependable alternatives such as renewable energies. Biomass is a free and abundant source of renewable energy. Municipal solid waste (MSW) as one of the main categories of biomass has always been an issue for metropolitan cities. It has, however, a high potential for biogas production. In this study, the technical and economic aspects of generating electrical power through solid oxide fuel cells (SOFCs) powered by injecting biogas derived from Tehran's MSW, as a case study, are investigated. The main objectives of the current study are to identify the power generation capability of the process and find out if it can result in a competitive energy resource. The total amount of obtainable methane through anaerobic digestion of MSW and then the achievable power generation capacity by using the obtained biogas are computed using the electrochemical relations inside the SOFC. The economic calculations are carried out to estimate the final price of the generated electricity, taking into account the major capital and ongoing costs of the required equipment. The effect of variations of MSW composition on the power generation capability and final electricity price is also studied. Moreover, the application of a gas turbine (GT) with the SOFC as a hybrid SOFC–GT system to recover the produced heat by SOFC and its effect on the power generation capability and the final electricity price are investigated. Results indicate that around 997.3 tons day−1 biomethane can be generated using Tehran's MSW. By using the SOFC, the produced biogas can generate 300 MWAC electrical power with a final cost of $0.178 kWh−1. By using the hybrid SOFC–GT, the electrical power capacity is increased to 525 MWAC, and the final electricity cost drops to $0.11 kWh−1, which indicates its competitiveness with other common energy resources in the near future, especially by considering different governmental subsidy policies that support renewable energy resources. The considerable environmental benefits of the proposed procedure, from both MSW management and CO2 emission reduction points of view, make it a promising sustainable energy resource for the future.
