F1.1 Closed Loop Organic Waste Management To Make Our Cities More Sustainable
8 am – 8:20 am PDT
11 am – 11:20 am EST
F1.1 Closed Loop Organic Waste Management To Make Our Cities More Sustainable
Globally, all nations are moving towards a more sustainable use of resources. The key challenge is to move beyond the perception of ‘waste as a problem’ to ‘waste as a resource’. Small scale AD technology can be applied in cities, next to, or even inside building eliminating the need to transport organics offsite. Food waste is eliminated in the process of anaerobic digestion, where a large amount of biogas is generated, used to produce green energy right at the place of installation. The by‐products are valuable fertilizer, water & heat which when integrated with urban farming, create a closed loop urban solution and have a major impact on GHG emissions. Micro gas grids can support this type of deployment. the final hurdle is regulatory as most building regulations do not cover the production of gas onsite.
QUESTIONS
1. What cities are implementing in building technologies?
2. Can this type of solution be retrofitted to older buildings or just incorporated in new build?
3. Can these systems be used for waste water as well as food waste?

F1.4 Overcoming the Pandemic and its Impact of Medical Waste on the Environment
Our goal is to spread awareness regarding the importance in reducing the amount of waste and work toward a greener environment. While preventing a shortage in PPE for our healthcare professionals and avoiding the possibility of reinfection, we must spread constant awareness about protecting our planet. Dental providers and dental schools contribute to a large amount of waste and after acknowledging the problems in early 2020, we decided to continue to share this knowledge. Prior to the COVID-19 pandemic, we presented at national conferences and school meetings with both students and faculty to demonstrate how crucial it is to limit waste of masks, gowns, booties, and gloves to help our environment. Now, in this new normal, we acknowledge how crucial it is to protect our healthcare professionals against COVID-19, while also finding the proper balance in distributing and tossing out our used waste properly. The question we are asking while reviewing published articles and using our own clinical photos is, how can we reduce the amount of waste? With this responsibility, comes our role to work together to dampen our profession’s negative impact surrounding waste.

F2.1 Economical Underground Pumped Storage Development using TBMs
10:30 am – 10:50 am PDT
1:30 pm – 1:50 pm EST
F2.1 Economical Underground Pumped Storage Development using TBMs
Over 95% of the currently available energy storage in the US is provided by conventional pumped storage utilizing existing topographic features to provide the head required for an economical project. Large parts of the United States do not have the topography to support the development of conventional pumped storage. Nelson Energy with Golder Associates has developed a conceptual design to utilize tunnel boring machines to excavate an underground reservoir to develop a closed loop project with an estimated cost less that half the cost of batteries for a storage duration of 12 hours. Nelson Energy received a DOE prize in 2018 for innovative pumped storage development. The presentation will describe this concept and its applicability throughout the US. Major Advantages of Underground Hydroelectric Pumped Storage:
-Energy Storage Cost-12 hours- $220/kWh versus $469 /kWh for batteries – Essentially Environmentally Benign – Can be sited near existing transmission at many locations -Uses well developed generation technology – Can be developed in many parts of the US–Competent Bedrock is present in 38 States – Preliminary design, equipment & estimated costs can be cloned to different sites – Pumped storage can provide a full range of ancillary benefits including system inertia.
F2.2 Long Duration Energy Storage – What’s Available?

F2.2 Long Duration Energy Storage - What's Available?
Long duration energy storage is a new tag line widely discussed in the industry. Lithium ion and even flow batteries are established in the market and commercially available. Lithium ion technology has historically made sense for 6 hour and shorter durations. In addition to flow battery technologies, this presentation will provide an overview of other long duration technologies being contemplated or commercialized within the industry.
F2.3 State Siting Regulation of Energy Storage Resources
11:10 am – 11:30 am PDT
2:10 pm – 2:30 pm EST
F2.3 State Siting Regulation of Energy Storage Resources
Many states are setting aggressive mandates to transition away from fossil fuel-based electric generation. Wind and solar are popular candidates to replace traditional coal- and gas-fired turbines, but on their own are generally intermittent and non-dispatchable resources. Deployment of utility-scale energy storage resources will be a critical component of any plan to facilitate this transition.
Energy storage developers should carefully assess whether their project requires approval from state siting regulators. States typically require utilities and other energy infrastructure developers to obtain siting approval before beginning construction. Many state siting laws were originally implemented decades ago to address siting of “traditional” utility infrastructure like power plants, electric transmission lines, and intrastate gas pipelines. Few have been sufficiently updated to reflect recent developments in energy infrastructure and public policy priorities. This begs an important question: are energy storage systems (like batteries) subject to state siting requirements as generation or transmission assets?
F2.4 Financing Renewable Energy and Storage Projects
11:30 am – 11:50 am PDT
2:30 pm – 2:50 pm EST
F2.4 Financing Renewable Energy and Storage Projects
The development and construction of renewable energy and storage projects requires significant financial investment. Successful developers use non-recourse project financing as a source of low-cost capital and tax equity financing that monetizes tax credits. Maximizing the value of these funding sources for distributed generation and utility-scale projects requires careful planning and deliberate implementation. Noah Pollak, a partner at Norton Rose Fulbright, will provide an overview of project finance and tax equity structures, and take a deeper dive into key considerations for project developers to focus on to make their projects the most attractive to financiers and investors.

2:50 pm – 3:10 pm EST
F2.5 Lithium Battery Safety
It’s tempting to think that energy storage can start to truly transform the grid as soon as the financial benefits clearly outweigh the costs, but there’s more work to do. Lithium batteries still carry more risk than many people wish to accept. This presentation explains why people underestimate battery risks and how to evaluate lithium batteries for safety. It also offers a use case in project design for resilience.
QUESTIONS
1. How do we calculate the value of resilience and flexibility from storage?
2. How can we compare resilient batteries with subsidized insurance?
3. Please identify up to five tests of a battery cell’s thermal runaway characteristics
F2.6 Locational Drivers for Utility-Scale Polar PV Farms
12:10 pm – 12:30 pm PDT
3:10 pm – 3:30 pm EST
F4.4 Locational Drivers for Utility-Scale Solar PV Farms
This research investigates the site suitability/selection process for large solar photovoltaic (PV) farms. We use a comprehensive suite of variables that are positive locational drivers, including: 1) economic factors (factors that positively impact development and operations costs); 2) critical infrastructure and high energy users (facilities that rely on cheap and reliable power); and 3) workforce (factors related to having a locally ready workforce for such projects). We employ advanced measurement procedures and methods to assess these decisive factors, comprehensively, offering a more sophisticated path forward for utilities and developers in terms of where to site solar PV farms.

F3.1 Zero to One and the Electric Grid
1 pm – 1:20 pm PDT
4 pm – 4:20 pm EST
F4.2 Zero to One and the Electric Grid
In Peter Thiel’s book, “Zero to One”, a question is posed: “What important truth do very few people agree with you on?” The book goes on to describe how these lost truths become secrets and explains why no one is looking to explain or investigate. Given the fact that one third of all carbon emissions in the US are the result of burning fossil fuels to generate electricity and most utilities today are rewarded on incremental improvements to a broken infrastructure, perhaps there are many secrets to explore. What truths would emerge if new data and an awareness of the impacts were applied to improve the energy delivery market? Using the framework outlined in Peter’s book, this presentation will discuss some of the secrets within the utility grid and the challenges faced to incorporate new clean generation technologies.

F3.3 The Effect of Renewables on Fossil Fuel-Fired Generation
The power sector is subject to continuously changing energy market forces, such as customer preferences, new technologies, public policy, regulation, and the cost of renewables. Critical to the business strategy are flexibility, the ability to pivot and adjust as markets and circumstances change, while continuing to fulfill the utility’s obligation to serve. Many companies will continue to fulfill their obligation to serve by providing a reliable and resilient grid for all customers. This presentation will focus on the effect of increased renewable energy generation at the expense of firm fossil fuel-fired generation and its impact on the need for a reliable and resilient grid. Specifically, the design of the transmission system has traditionally been based on the inherent characteristics of synchronous generators (i.e., firm fossil fuel-fired generation) to effectively deliver power from central station generators to distribution load centers while optimizing efficiency and maintaining a high level of reliability. The proliferation of solar- and wind-generated renewable energy has resulted in a displacement of synchronous generation, reducing the inertia of the overall system and lessening grid stability. This presentation will discuss how the power sector is addressing these concerns and how the operation of fossil fuel-fired generation will need to evolve to ensure stability of the system.
F3.4 Thermal Energy Storage Technology for the Application in Power Systems
2 pm – 2:20 pm PDT
5 pm – 5:20 pm EST
F3.4 Thermal Energy Storage Technology for the Application in Power Systems
The STEM-RES technology consists of thermally insulated modules containing fluidized bed sand, capable of storing thermal energy at high temperature (over 600 °C). The sand can be heated both through exchange coils crossed by superheated steam, and through electrical resistances. STEM-RES modules can therefore act as accumulators for both thermal energy and electricity, obviously transformed into heat. The return of the stored energy takes place through the production of superheated steam, which can be used as it is in industrial processes, or operate a turbo alternator unit for the production of electricity.

F3.6 Sensible Sustainability TM
At Calpine Energy Solutions, we view renewable energy purchases as an important slice of the energy management portfolio. We employ a sustainable business process with our clients to enable datadriven decisions evaluated through a spectrum of five criteria: governance, cost, risk, carbon and reporting. We refer to the result of utilizing this prism as Sensible SustainabilityTM because the decisions informed by it should be logical in relation to all five criteria.
Calpine Energy Solutions has developed powerful analytical tools and data visualization platforms to support Sensible SustainabilityTM , but the process starts with asking good questions because the answers help define the yang, or governance, that should be applied. We colorfully call our questions the “How Do You Knows”: how do you know when to buy, how do you know how much to buy, how do you know how long to buy, and how do you know how well you performed? The introduction of renewable energy to consumer portfolios in simple terms, adds two additional questions to that list. How do you know where to buy and how do you know what to buy?
