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.

Grid Features in the TIMES-based Japan ModelIEA-ETSAP
1) The document describes updates made to the Japan Multi-regional Transmission (JMRT) model to include grid features, allowing for analysis of high renewable energy penetration scenarios.
2) The model was modified to include 351 grid nodes to represent Japan's 47 prefectures, with renewable energy potential and demand allocated to nodes based on location.
3) Simulations examined scenarios with 25-55% variable renewable energy (VRE) shares by 2050, and the impact of grid infrastructure expansion. Without expansion, high VRE led to increased marginal electricity costs between regions.
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.

V2G: Measuring Electric Vehicle Drivers’ Willingness to Co-create Flexibility...IEA-ETSAP
Electric vehicle drivers' willingness to provide flexibility to the electric grid was studied through a choice-based conjoint analysis survey of 301 people in Switzerland. The study found that drivers required a flexibility premium of 3.85-45.16 CHF per month to allow different levels of access to their vehicle batteries for grid services. A comparison of electric vehicles, heat pumps, and PV+battery systems showed that flexibility provision came at a higher implicit discomfort cost for heat pumps than electric vehicles or PV systems. While some willingness to provide flexibility was found, further research is needed to understand differences in willingness across technologies and locations.
The document discusses different electrical machines used for wind power generation. It begins with an introduction to wind power production and then describes various electrical generation schemes currently in use worldwide. These include constant speed wind turbines connected directly to the grid, variable speed turbines with a doubly-fed induction generator, and direct drive turbines with a synchronous or permanent magnet synchronous generator. The permanent magnet synchronous generator system directly connected to the grid via a full-scale power converter is highlighted as one of the most promising designs currently used due to its high efficiency and robustness.
This study investigates integrating molten carbonate fuel cells (MCFC) into steam-assisted gravity drainage (SAGD) facilities in Alberta's oil sands to reduce greenhouse gas emissions. MCFC could capture 90% of CO2 emissions from SAGD steam generation and provide low-carbon electricity. Modelling shows retrofitting MCFC to 27 SAGD facilities by 2037 could reduce emissions by 25 megatons per year by 2037 by capturing SAGD emissions and displacing coal power. Overall, integrating MCFC across the SAGD industry could reduce cumulative emissions by 865 megatons to 2060 while enabling early coal plant retirement in Alberta's electricity grid.
This document discusses the potential of solar energy and the prospects and challenges of harnessing it. It notes that solar energy could generate over 150 times the world's current energy demand if 5% of land area was covered with solar panels. However, integrating large amounts of solar power faces technical challenges related to efficiency, grid integration due to variability, and energy storage. Economically, the levelized cost of energy from solar is currently higher than conventional sources. National and state policies aim to overcome these challenges through targets and incentives to promote the growth of solar power in countries like India.

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.

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.
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.

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.
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.

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.
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.

15. Conclusions
▪ Explicitly targeting renewable generation may not fully ensure power sector
decarbonization as fossil-fuel generation will continue to contribute to CO2 emissions
▪ An instrument like carbon tax can expedite decarbonization by promoting investments
in green technologies and improving efficiency of existing thermal power plants
▪ Methodology to classify RE sources in different classes, as opposed to increasing the
resolution of planning model, reduces computational complexity
▪ For a power system dominated by inflexible generation, incorporating all UC
constraints is vital to ensure adequate quantification of flexibility resources and analyze
emission related polices
▪ Computational efforts can be further reduced by removing ramping constraints (if
flexibility is not a concern)
