Energy-Water-Land Nexus in Germany: A case studyIEA-ETSAP
This document presents a case study on the energy-water-land use nexus in Germany. It develops a methodology to integrate a water and land use model within an existing energy system model called TIMES PanEU. The models are used to generate scenarios that meet different climate targets while accounting for interactions between the energy, water and agricultural sectors. The results show that considering the nexus leads to greater use of wind and solar, less biomass cultivation, and slightly faster decarbonization. Stricter climate targets increase irrigation water demand and total water use. Measures like wastewater reuse and lowering agricultural product demand could help reduce pressures on land and water resources while meeting climate goals.

Addressing demand uncertainty in long-term planning modelsIEA-ETSAP
This document discusses addressing demand uncertainty in long-term energy planning models. It compares deterministic models using planning reserve margins to stochastic models that capture expected operational costs under different demand scenarios. Capturing multiple demand scenarios changes the optimal capacity mix by accounting for the expected costs of meeting variable demand. Stochastic models also endogenously assess renewable energy capacity credits over multiple time periods rather than fixing credits based on a single peak period. Accounting properly for demand uncertainty and renewable intermittency provides more robust optimal capacity planning outcomes.

Ongoing Macro-Stand Alone and CGE modelling approaches at UCL Energy InstituteIEA-ETSAP
This document summarizes ongoing macroeconomic modeling work at University College London's Energy Institute. It describes the UK Times Model energy systems model and efforts to link it with a macroeconomic stand-alone model and a computable general equilibrium model. The macro-stand alone model allows exploring the impact of different capital-energy substitution elasticities. Preliminary results show low GDP impacts of climate policies but higher total system costs. Future work includes further comparison of macro modeling approaches and linking the models to assess whole energy-economy impacts of policies.
Evaluation of the role of energy storages in Europe with TIMES PanEUIEA-ETSAP
This document summarizes the results of scenario analyses conducted using the TIMES PanEU energy system model and ESTMAP storage database to evaluate the role of energy storage in Europe. The analyses found that increased electricity demand and electrification of the energy system are needed to meet EU GHG reduction targets. Additional electricity storage capacity investments from 2030 onward are also needed to integrate more variable renewable energy from wind and solar. First investments are in diabatic CAES and battery storage, shifting later to pump storage and adiabatic CAES as costs decrease. Energy storage, along with other flexibility options, helps reduce GHG emissions compared to scenarios relying more on natural gas storage.

The document summarizes the ESTMAP project which mapped existing and potential energy storage sites across Europe and analyzed their role in future energy systems using modeling tools. Key points:
- ESTMAP compiled a database of over 4,200 potential and existing natural energy storage sites for electricity, gas and heat across Europe.
- The database was used as input for the TIMES and PowerFys energy systems models to optimize the configuration of storage sites and power plants and assess the role of energy storage in the energy transition.
- Scenario analyses were conducted for Europe, Germany, Belgium and the Netherlands looking out to 2030 and 2050 to understand the role of storage under different policy and cost assumptions like higher solar and lower
Energy storage can help integrate renewable energy sources by storing excess production for times when supply is low. However, current storage technologies are too expensive to deploy widely. Alternatives include improving demand management and allowing generators to better adjust output to changing demand. Further development is needed to reduce storage costs before it can be broadly implemented on power grids.

Emission impacts of marginal electricity demand in FranceIEA-ETSAP
This document summarizes research on estimating the carbon dioxide (CO2) emissions impacts of marginal electricity demand increases in France out to the year 2050. The research combined a bottom-up model of future electricity demand with a TIMES model of France's electricity supply system. Preliminary results for one scenario showed CO2 intensities of electricity could reach up to 300 gCO2/kWh by 2050, varying seasonally and hourly. Applying a carbon tax reduced CO2 intensities and even led to negative emissions some hours as biomass with carbon capture and storage displaced other generation. The analysis highlighted the need to better represent plant dynamics and interactions to accurately assess hourly CO2 impacts.

Our assumptions about the Levelised Cost of Electricity from renewables are wrong. This presentation looks at how we should correct our estimates by taking note of the fall in the real cost of capital for index-linked assets which, for example, includes PV in the UK.
The document provides an overview of a meeting of the Irish Wind Energy Research Network. It discusses trends in wind energy in Ireland including key statistics and targets for 2030. It outlines SEAI research updates including funding calls and collaboration in IEA wind energy research tasks. Projections from climate models show increases in wind speeds and wind power potential for Ireland by mid-century under climate change scenarios. High-resolution regional climate modeling can provide more detailed projections for Ireland to inform wind energy and policy planning.
Economy-wide Implications of Policy and Uncertainty in the Power Sector of So...IEA-ETSAP
This document summarizes the key findings of a study that used linked energy-economy models to analyze the economy-wide implications of different power sector policies and uncertainties in South Africa. The study found that building new nuclear power was generally more expensive than renewable energy or maintaining coal, and increased electricity prices and GDP losses. Scenarios with a renewable target or lower nuclear costs had lower costs and smaller economic impacts. Imposing an early nuclear program reduced economic growth more than allowing nuclear to develop freely based on its own economics.

This document summarizes a presentation about optimizing hydrogen electrolyser capacity investment in Australia given the country's goals for increasing renewable energy and hydrogen production. It finds that the optimal approach balances upfront capital costs for electrolyser capacity against utilizing that capacity flexibly to take advantage of variable renewable electricity generation. Maintaining a minimum baseline utilization of electrolyser capacity is important despite flexibility in ramping. The tradeoff is between investments that can flexibly use available energy and co-optimizing within the broader energy system.

The document discusses a study conducted to determine the least cost generation capacity mix for the CSIR campus in Pretoria from 2016-2022 under different energy usage scenarios. The study used PLEXOS modeling software to optimize the capacity of new solar PV, wind, biogas, and battery installations to minimize total electricity costs while meeting campus demand and considering Tshwane's time-of-use electricity tariff structure. The results show that optimizing renewable capacity additions can significantly reduce total electricity costs compared to maintaining only existing renewable systems.
Best practices for Solar and Wind power system case studiesLeonardo ENERGY
Power system impact studies are often the first steps taken towards defining renewable targets. It is important that commonly accepted standard methodologies are applied related to these issues. IEAWIND and IEA PVPS have issued Recommended Practices for Wind/PV Integration Studies to provide researchers, consultants, and system operators with up-to-date guidelines on how to perform renewable power system studies.
The second edition of the report published in 2018, extends recommendations for wind integration studies to also include solar PV and distribution networks, on top of transmission network issues.
Recommendations are based on more than 10 years of work within the International Energy Agency Wind Technology Collaboration Programme (IEA Wind TCP) Task 25: Design and Operation of Power Systems with Large Amounts of Wind Power and the IEA Photovoltaic Power System Programme (PVPS TCP) Task 14: High Penetration of PV Systems in Electricity Grids.

Applying science fiction to approach the futureIEA-ETSAP
The document discusses using science fiction to think about future energy systems. It proposes applying system analysis models to explore different technology combinations that meet future energy needs. However, it notes that these models do not consider social factors like behavior and justice. It suggests using genres like climate fiction and solar punk to bring more collective narratives about energy futures. Specifically, it advocates using a hackathon approach to gather knowledge and create imaginary fiction stories around different future scenarios to help build worlds and consider the human aspects of energy system design.
Will it leak?: Discussions of leakage risk from subsurface storage of carbon ...IEA-ETSAP
The document discusses carbon capture and storage (CCS) and the potential risks of leakage from subsurface storage of carbon dioxide. It provides background on CCS, explaining that carbon dioxide is captured from industrial sources and injected underground for permanent storage. It then discusses four main types of potential subsurface leakage: 1) capillary leakage if seal rocks have larger particles, 2) exceeding the fracture gradient of the seal, 3) leakage along or across faults, and 4) leakage from new or legacy boreholes. The document analyzes case studies of both CCS and carbon capture, utilization, and storage (CCUS) projects to illustrate examples of each leakage type. It concludes that CCS/CCUS has a low overall risk but is not
Long-Term Decarbonization Pathways In Emerging Economies: Insights From 12 Mo...IEA-ETSAP
This document summarizes the preliminary results of a study comparing long-term decarbonization pathways in 12 developing countries and 2 regions modeled using the Electricity Planning Model. Key findings include:
1) Ambitious decarbonization would require annual investments of 1-3% of GDP, compared to around 1% for business-as-usual scenarios.
2) Renewables, led by solar, would dominate capacity additions. Conventional plants would operate more flexibly to integrate variable renewables.
3) Achieving deep decarbonization would significantly increase energy costs but carbon prices of $20-120/t could enable cost-effective emissions reductions.

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.
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.
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.
Climate Change All over the World .pptxsairaanwer024
Climate change refers to significant and lasting changes in the average weather patterns over periods ranging from decades to millions of years. It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity
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.
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.

This presentation is for us to know that how our Environment need Attention for protection of our natural resources which are depleted day by day that's why we need to take time and shift our attention to renewable energy sources instead of non-renewable sources which are better and Eco-friendly for our environment. these renewable energy sources are so helpful for our planet and for every living organism which depends on environment.
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.
