A system includes an algae bioreactor that contains an algae slurry, a heat exchanger in fluid communication with the algae bioreactor to receive the algae slurry from the algae bioreactor and heat and increase a pressure of the algae slurry, and one or more valves and a flash vessel in fluid communication with a discharge of the heat exchanger to flash the algae slurry and create steam and algae biomass. A separator receives the algae biomass from the flash vessel and separates oils from the algae biomass to generate a biofuel.

An autonomous control system can be used with one or more systems or components to improve the operation of the systems or components. For example, an autonomous control system can be used in combination with a biorefinery system to improve the operation of the biorefinery system.

A process for treating waste water, including the steps of extracting by forward osmosis treated water from a wastewater feed stream and transferring it to a saline draw stream, and extracting from the saline draw stream treated water by a reverse osmosis process.

A device for producing energy from waste including a power generator, a digester, and .a generator utilizing biodiesel, active coal, tar, and ashes. The latter includes a purification chamber, a gas generator, a radiator, a compressor, and a reactor. The device includes an HMF producer comprising a primary treatment tank, a pump, a reactor, an extractor and a purification tank. The power generator may be at least one of a diesel motor, a gas turbine and steam cycle. The digester is structured to produce biogas.

Atmospheric carbon has risen above 400 parts per million (ppm) crossing a threshold that endangers climate stability. Greenstone Device biotechnology enables consumers, businesses, municipalities and nations to mitigate their carbon output by providing a platform for capturing emitted carbon directly from the atmosphere, and converting that carbon into organic biomass fertilizer.

A power-generation system having a combined heat and power plant and a fermentation plant has an electrolysis plant, which is connected by lines to both the combined heat and power plant and to the fermentation plant. This arrangement enables a method in which heat from a combined heat and power plant can be used for a fermentation plant and additionally heat from an electrolysis plant can be used for the fermentation plant, whilst the oxygen from the electrolysis plant is used for the combined heat and power plant.

In one embodiment, a sustainable hydroponic growing system comprises at least one hydroponic growing unit, an algae growing unit configured to produce an algae biomass, a biofuel system configured to process the algae biomass to produce a bioethanol fuel and a solid oxide fuel cell configured to use the bioethanol fuel as at least one source of fuel to produce electrical power for use by the at least one hydroponic growing unit. In one embodiment, the solid oxide fuel cell is further configured to produce steam that serves as a water source for the at least one hydroponic growing unit and/or the algae growing unit.

A bioenergy management system and method for generating and supplying on-demand auxiliary electrical power is disclosed. The system/method includes a biogas generation unit (BGU) that produces biogas from dairy farm manure and stores the biogas in a biogas storage unit (BSU). An stored energy electric generation unit (SEGU) converts the stored biogas to electricity. A biogas control unit (BCU) measures the quality and quantity of biogas stored in the BSU and calculates available electric power (AEP) from this information. Depending on auxiliary electrical power requirements, a utility control unit (UCU) initiates an on-demand request for electric power (REP) to the BCU using a producer communication device (PCD)/utility communication device (UCD) data link. The BCU processes the REP from the UCU and negotiates electrical power (NEP) quantity. The BCU may electrically connect the SEGU to an electric transmission grid (ETG) to allow instantaneous/scheduled NEP delivery to the ETG.

An improved system of generating renewable energy is comprised of a specific configuration of mechanisms, materials, and processes that all function together as a single symbiotic system. In accordance with a preferred embodiment, the system cultivates aquatic biomass, then extracts triglycerides from said biomass. The extracted triglycerides are converted into biodiesel through transesterification. During the operation of the system, a continuous output of biofuel, thermal energy, steam, and electricity, is efficiently produced. These yields are precisely measured and repurposed as energy input at various points throughout system processes, thus resulting in a surplus output. Any embodiment of the disclosed system will generate a continuously renewable final product of biofuel and power.
