When you think of renewable energy sources, algae biodiesel systems may not be the first thing that come to mind. However, these systems are becoming increasingly popular due to their ability to produce fuel from fast-growing light and water loving species.
As algae has become a viable platform for creating biofuel, the debate has been raging between open and closed algae biodiesel systems; is one better than the other? In this blog post we will delve into the strengths and weaknesses of both system types so that professionals can decide which option is best suited for them.
Open vs Closed Algae Biodiesel System
1
What is an Open System Algae Biodiesel System and how it works
An open algae biodiesel system explores the algae's capability to potentially purify wastewater and concurrently produce biofuel. In such algae systems, wastewater is poured into large algae ponds, also known as bioreactors and algae ponds, which are exposed to light for algae to grow and increase their biomass.
The algae convert organic or inorganic nutrients from the wastewater into a carbon source, facilitating them to continuously reproduce and produce biofuel, like biodiesel. The produced fuel can then be stored for later use or be converted into electricity via combustion engines.
Further, by using this particular system along with other conventional waste management practices, contamination levels of water can be managed effectively while biofuel simultaneously can be generated in an economical way.

Advantages of the open Algae system
An open system of algae biodiesel production has some distinct advantages over a closed one. In an open system, nutrients such as water and light are readily available for the algae, allowing it to flourish and produce larger productivity yields than in a closed system.
Furthermore, since waste products created from the growing process are able to be dispersed in an open system, there is no need for additional specialized filtration systems as there is with a closed system - this saves money and resources in the long term.
Open systems reduce risk by having fewer potential points of failure and require less maintenance overall than a closed one. Finally, because sunlight can reach into an open algae system whether through the water surface or artificial lighting, the algae can thrive despite any drops in temperature or other changes in the environment due to natural weather phenomena.
The advantages associated with an open algae biodiesel system make it a great option for those looking to maximize their output results while minimizing risks.

Disadvantages of the open algae system
The open algae biodiesel system has several drawbacks. Chief among them is the risk of contamination from microorganisms, which can adversely affect the productivity of the operation and even cause major disruptions in their process.
Moreover, this system requires significant resources to stay clean and make sure that the algae culture is adequately maintained. Additionally, the constant exposure to air conditions can be detrimental to some species of algae, so it may not be suitable for certain applications where reliability is essential.
Furthermore, due to its open design, sunlight reaches the algae culture directly which can lead to overheating which further reduces its efficiency.

What is a Closed System Algae Biodiesel System and how it works
A closed algae biodiesel system is a type of algae bioreactor that confines the algae used to produce biodiesel within a confined and controlled environment.
It is different than an open algae system in that it employs physical barriers and water recirculation in order to harness the algae. Unlike an open algae system, this type of reactor ensures that chemistry, temperature, and other environmental factors can be better moderated and monitored leading to more efficient production.
Due to this control over algae production, yields are much higher than in an open system algae biodiesel system, making them the preferred choice for large-scale production of algae biodiesel.

Advantages of the closed system
The closed algae photobioreactor system offers many advantages in terms of algae biodiesel production. This system seals off the algae from its environment, thus protecting it from harmful external contaminants.
By creating a sterile and controlled environment, algae growth is optimised with control over factors such as temperature, light levels, pH balance, nutrients and more. This type of environment eliminates unpredictable growth patterns due to external sources which can lead to long recovery times and the loss of valuable algae biomass.
Furthermore, algae are prevented from entering water systems or becoming airborne within this type of system, so there is minimal risk of harming or contaminating nearby habitats.
The efficient closed algae biodiesel production process associated with closed systems provides a reliable platform for commercial-scale mass cultivation without sacrificing quality ensuring economical viability.

Disadvantages of the closed algae system
The closed algae system, which involves growing the algae in sealed tanks or bioreactors and then harvesting it, has certain drawbacks worth noting.
As a more advanced system, it is premium-priced compared to an open sheet system. Additionally, oxygen entering the tank is essential for successful growth but can also introduce bacteria and other organisms that contaminate the product if not properly regulated.
Being an advanced technology, access to technical expertise to maintain and troubleshoot a closed algae system may be difficult or expensive to find. Finally, higher production costs may result due to the energy needs of elevated temperatures and gas injections required for optimal growth in these systems.
In Conclusion,
Both the open and closed system algae biodiesel systems have their own distinct advantages and disadvantages. Ultimately, it is up to you to determine which system will best fit your needs.
Whether an open or closed system is chosen, both are great options for those looking to reduce their carbon footprint with sustainable sources of energy. What's important for those interested in taking advantage of these systems is to do their research and learn more about the differences between each so that they can make an informed decision about which one will work for them.
It's clear that both the open and closed system algae biodiesel systems have different applications, with each offering unique benefits depending on individual circumstances. With a better understanding of how each works, you can take the necessary steps towards utilizing this technology in the best way possible.
