Concentrated solar power systems use mirrors to focus sunlight and heat a fluid to produce steam that drives turbines to generate electricity. There are three main types: linear concentrators use curved mirrors to heat fluid in tubes; dish/engine systems use mirrored dishes to concentrate sunlight onto receivers connected to Stirling engines; and power tower systems use many heliostat mirrors to focus sunlight onto a receiver at the top of a tower to heat a fluid and produce steam. Concentrated solar power is advantageous because it is non-polluting, can displace fossil fuel plants, and is efficient and cost-effective to deploy relatively quickly to reduce carbon emissions compared to natural gas systems. Ideal places for concentrated solar power include desert regions of Australia and Africa

With the development of industry and
agriculture, a great amount of energy such as coal, oil
and gas has been consumed in the world. Extensive
use of these fossil energies deteriorates a series of
problems like energy crisis, environmental pollution
and so on. Everybody knows that the fossil energy
reserves are finite, some day it will be exhausted.
It is possible that the world will face a
global energy crisis due to a decline in the
availability of cheap oil and recommendations to a
decreasing dependency on fossil fuel. This has led to
increasing interest in alternate power/fuel research
such as fuel cell technology, hydrogen fuel, biodiesel,
Karrick process, solar energy, geothermal energy,
tidal energy and wind. Today, solar energy and wind
energy have significantly alternated fossil fuel with
big ecological problems.
With the development of the science and
technology, power generation using solar energy and
wind power is gradually known by more and more
people. And it is widespread used in many developed
countries. The merits of the solar and wind power
generation are very obvious-infinite and nonpolluting.
The raw materials of the solar and wind
power generation derived from nature, and wind
power generation can work twenty-four hours a day,
solar power generation only works by daylight. In
addition, this kind of power generation has no
exhaust emission and there is no influence to the
nature. But it also has some shortcomings. Because
of the imperfect of the technology, equipment of the
solar and wind power generation is very expensive.
By far, it cannot be widely used.
In addition, solar and wind power
generation system affected by the changing of the
weather very much, so it has obvious defects in
reliability compared with fossil fuel, and it is difficult
to make it fit for practical use the lack of economical
efficiency .Because of these problems it needs to
increase the reliability of energy supply by
developing a system which interacts Solar and wind

IRJET-Review on Solar Thermal and Photovoltaic Energy SystemIRJET Journal
This document summarizes and compares solar thermal and photovoltaic energy systems. Solar thermal systems indirectly generate electricity by using solar collectors to heat a liquid or gas, then converting the heat to electricity. Concentrated solar power is a type of solar thermal that uses tracking mechanisms to focus sunlight and achieve higher temperatures and efficiencies. Photovoltaic systems directly convert sunlight into electricity using solar panels without heat exchange. While photovoltaic systems have higher energy production, even at low light levels, their limitation is lack of cost-effective electricity storage. Solar thermal systems allow for thermal energy storage at low cost and therefore can provide dispatchable electricity production. Both systems show potential but differ in energy conversion methods and ability to store excess energy

This document discusses microgrids and renewable energy integration. It notes that microgrids are decentralized, self-sufficient power networks that are generally located in regions rich in renewable energy resources. Integrating high levels of renewable energy into microgrids presents challenges in maintaining grid stability due to the intermittent nature of renewable sources. The document proposes that intelligent control systems and grid stabilization technologies can enable high renewable energy penetration of up to 100% while keeping the voltage and frequency stable and maximizing fuel savings and return on investment. ABB provides solutions like the Remote Microgrid Controller and PowerStore flywheel system to stabilize grids and maximize the benefits of integrating renewable energy at high levels.

An agent based approach to virtual powerplants with wind power generation and...Arjun Anil
This document proposes an agent-based approach to creating virtual power plants (VPPs) made up of wind power generators and electric vehicles (EVs). A VPP aggregates these distributed energy resources to sell power. The VPP uses EVs to store excess wind power for later supply to the grid. An optimization scheme determines the day-ahead bid to maximize VPP profits by considering how much power to supply directly from wind and EVs. Experimental results show the VPP achieves higher profits than wind power alone, with profits decreasing as the payment rate to EVs increases. The VPP provides a more reliable power source than intermittent wind power generators.

Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.
Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.
Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
