CCS as least-cost options for integrating intermittent renewables in low-carb...Global CCS Institute
Intermittent renewable energy sources (intermittent‐RES) such as wind and solar PV can be a key component of the resulting low‐ carbon power systems, but their intermittency requires more flexibility from the rest of the power system to maintain system stability. In this study, the efficacy of five complementary options to integrate intermittent RES at the lowest cost is evaluated with the PLEXOS hourly power system simulation tool for Western Europe in the year 2050. Outcomes of the study show that amongst the various options to reduce system’s costs one of the most effective is the implementation of CCS at natural gas‐fired power plants.

Webinar - Primary energy factors for electricity in buildingsLeonardo ENERGY
There is no unified approach in European regulation of how to calculate primary energy when assessing energy performance of buildings. Instead, member states can decide on their own method of calculation of primary energy. As the share of renewables will progress towards 2050, the primary energy factors for electricity in Europe will also be subject to changes over time.
Related to the energy performance of buildings, the question is in what way different (due to national electricity mix or methodology) and changing (due to increased share of renewable electricity) primary energy factors for electricity influence decisions on a political level and on a level of individual building designs, especially with regard to space heating options (gas vs. electricity). From a point of view of making the electricity supply more flexible, it could be desirable to increase the share of electricity for heating. The objective of this work was to assess to what extent this is stimulated (or hampered) by changing primary energy factors in building regulation of a number of countries.

Optimization of Economic Load Dispatch with Unit Commitment on Multi MachineIJAPEJOURNAL
Economic load dispatch (ELD) and Unit Commitment (UC) are significant research applications in power systems that optimize the total production cost of the predicted load demand. The UC problem determines a turn-on and turn-off schedule for a given combination of generating units, thus satisfying a set of dynamic operational constraints. ELD optimizes the operation cost for all scheduled generating units with respect to the load demands of customers. The first phase in this project is to economically schedule the distribution of generating units using Gauss seidal and the second phase is to determine optimal load distribution for the scheduled units using dynamic programming method is applied to select and choose the combination of generating units that commit and de-commit during each hour. These precommitted schedules are optimized by dynamic programming method thus producing a global optimum solution with feasible and effective solution quality, minimal cost and time and higher precision. The effectiveness of the proposed techniques is investigated on two test systems consisting of five generating units and the experiments are carried out using MATLAB R2010b software. Experimental results prove that the proposed method is capable of yielding higher quality solution including mathematical simplicity, fast convergence, diversity maintenance, robustness and scalability for the complex ELD-UC problem.
This document proposes a multi-objective framework for short-term scheduling of a microgrid considering cost minimization and emission minimization objectives. It formulates the problem as a mixed integer nonlinear program with constraints including power balance and unit generation limits. The Normal Boundary Intersection method is employed to solve the multi-objective problem and generate a Pareto front of optimal solutions. Simulation results are presented comparing the proposed approach to other methods.

A turbomachine is defined as a device that transfers energy to or from a continuously flowing fluid using one or more moving blade rows. Turbomachines are classified into two main categories - those that absorb power to increase fluid pressure like compressors and pumps, and those that produce power by expanding fluid to a lower pressure like turbines. They are further categorized based on the flow path, which can be axial, radial, or mixed, and by the compressibility and pressure changes in the fluid flow through the rotor.
Hydropower harnesses the energy of flowing water to generate electricity. Water is diverted from a river or reservoir through a penstock to spin turbines, which turn generators to produce electricity. Advanced turbine designs aim to minimize environmental impacts like fish injury and mortality. The DOE is funding projects to develop more fish-friendly turbine concepts and test designs that use gradual pressure reduction and minimize contact with blades to reduce stress on fish passing through turbines.

It aims to tap the state's significant potential for hydroelectric power (estimated at over 20,000 MW), as well as other renewable sources like biomass, waste-to-energy, solar, wind and geothermal power. Specific targets are set to develop over 1,000 MW of renewable capacity by 2020 through micro, mini and small hydro projects (600 MW), cogeneration (220 MW), biomass/waste (300 MW) and other sources. The policy provides measures like tax incentives to encourage private investment and help meet rural energy needs through decentralized renewable projects.
The document discusses accelerating hydropower development in India. It notes that while India has large hydropower potential, only a small portion has been developed so far. Recent renewable energy targets and expected electricity demand increases necessitate greater reliance on hydropower due to its ability to support the grid and balance the variability of renewables like solar and wind. However, hydropower development in India faces barriers like land acquisition challenges, environmental clearances, and lack of long-term power purchase agreements that increase costs. The document proposes an action plan to address these issues and create a level playing field for hydropower to attract more private sector investment and accelerate its development.
The hydropower sector in India has consistently failed to achieve its capacity addition targets each year since 2008-2009. As of November 2017, around 38 hydropower projects totaling 11,650.5 MW were facing significant delays and cost overruns. The average time overrun for hydropower projects is estimated at six years, with some projects delayed by over 10 years. Issues causing delays include land acquisition challenges, lengthy approval processes, rehabilitation concerns of local communities, and geological surprises. Cost overruns have also been substantial, with the average project seeing a breach of about 18.5 billion rupees. To address these issues, the government needs to streamline approvals, engage local communities, provide incentives for timely completion

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.
Recycling and Disposal on SWM Raymond Einyu pptxRayLetai1
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.

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.

Summary
1. JCOAL is conducting several projects under Indi Japan mutual cooperation
in both coal and power sector. Joint declarations at both past and the latest
India-Japan Energy Dialogues acknowledged such significance and
achievement of the Cooperation.
2. CEA-JCOAL Cooperation provided a good opportunity for materialization of
R&M as well as fruitful discussion and information exchange in CCT
transfer program.
3. In a targeted long plant life of nearly 50 years, high plant availability
possible through preventive maintenance. Higher economic efficiency
requires shift to condition based maintenance
4. Idemitsu has been providing technical services to coal users, creating the
further demand of coal, and making the most effective use of coal resources.
5. Applying our products and services, we propose optimum coal-blending and
boiler-operating conditions which lead to improved efficiency and trouble-
free operation in a boiler.
6. We, especially Japanese players in the coal power subsector in India are
anxious to work together with our Indian partners toward sustainable
development of Indian power sector.
