    NatGas Driving The Climate Crisis

    Oil and gas production is contributing even more to global warming than was thought, study finds

    Drew Kann, February 19, 2020 (CNN)

    “…Scientists say that atmospheric methane is now responsible for about 25 percent of the human-caused warming…[and] a new study finds that methane emissions from fossil fuels are between 25% and 40% larger than past research had estimated, revealing that oil and gas production is contributing far more to warming the planet than previously thought…[Sources of methane in the earth's atmosphere] can be divided into two categories: biological and fossil…Biological methane is released by the decay of plants and animals in environments like wetlands, but also from human activity like cattle farming, landfills and rice fields…[Fossil methane] can seep naturally from underground, or it can be released into the air by human extraction of oil and gas…

    ...[M]ethane concentrations in our atmosphere have soared by about 150 percent in the roughly two centuries since the Industrial Revolution…[The new research shows] that oil and gas production account for nearly half of all the methane in our air that is attributable to human activity…There is not as much methane as carbon dioxide in our atmosphere, but a molecule of methane has a global warming potential that is 20 times greater than carbon dioxide…[which means] the methane emissions associated with natural gas production are a serious problem for the planet…[H]uge amounts of methane are being released from oil and gas facilities around the US…” click here for more

    ORIGINAL REPORTING: Achieving A Distributed Energy System Could Require A Self-Driving Grid

    As utilities scramble to manage explosive DER growth, is power grid autonomy a solution? The U.S. electric grid could face hundreds of millions of distributed resource deployments in the near future. But optimizing these data points may exceed human ability.

    Herman K. Trabish, Sept. 11, 2019 (Utility Dive)

    Editor’s note: Real artificial intelligence and autonomy are still a long way off but there are some autonomous functions that can help with today’s challenges to managing an increasingly complex distribution system.

    Within a decade, there may be more distributed energy resources (DER) coming onto distribution systems than any utility control room can manage. An autonomous energy grid (AEG) could optimize those high levels of DER for the benefit of power system and DER owners, research under development by the National Renewable Energy Laboratory (NREL) shows. But if this groundbreaking system autonomy proves elusive, utilities could face voltage and frequency fluctuations, potential supply-demand imbalances or even outages, according to distribution system experts.

    NREL’s concept “is about controlling hundreds of millions of different kinds of devices in real time on a second-by-second basis," DOE Power Systems Engineering Center Director Benjamin Kroposki told Utility Dive. A successful AEG concept would require greater technical precision than autonomous driving and the Internet, the two most comparable examples in terms of data management, data analyst specialists and utility system authorities told Utility Dive. But the expected massive growth of DER makes NREL's ambition necessary, according to Kroposki.

    Residential solar installations are expected to grow approximately 8% annually through 2050. Behind-the-meter storage deployments are anticipated to hit almost 1.9 GW by 2024. Current forecasts project around 18.7 million EVs on U.S. roads in 2030. It is not unreasonable to imagine electricity customers a decade from now having up to five devices at a time — a rooftop solar system, a home battery, a smart thermostat, a smart water heater and an EV charger, said Kroposki. By that math, the 4 million customers in the San Francisco Bay area could leave PG&E with 20 million devices to manage.

    Utilities will also see rising penetrations of bulk system wind and solar generation that will create supply-demand imbalances that traditional control centers will not be able to manage simply by ramping supply up or down, he said. Instead, it will require managing demand, which could be done through DER technologies. But the sheer volume of DER could exceed a utility's ability to optimize. A comparable challenge is managing the Internet's hundreds of millions of data points, but the power system is under higher pressure to maintain precise moment-by-moment supply-demand balance and avoid any delays, he added.

    The basic element of NREL's theoretical AEG architecture is the optimization and control of a "cell," which can be a home or building energy management system and their controllable devices. Kroposki describes the AEG as "distributed cells with a hierarchical, scalable, reconfigurable and self-organizing control structure on top of them."

    The next level up may be the distribution circuit, and the level above that might be a substation, Kroposki said. "Each level's cells have parameters and constraints, like voltage, currents or system pricing, that they use to self-optimize and maximize self-optimizing at each level." Pilots are testing optimization algorithms… click here for more

    MONDAY’S STUDY: All About Storage

    Introduction to Energy Storage

    Faith M. Smith, January 23, 2018 (ClearPath)

    Energy storage can help the grid in so many ways – it allows us to save electricity for a more appropriate time or can be used in multiple applications to assist in balancing and maintaining the grid. While energy storage can be complicated, this paper is meant to break it into digestible pieces. The electricity grid is the centerpiece of the puzzle. The grid can be broken into three parts: generation, transmission, and distribution. In order to meet demand, utilities must be prepared to distribute electricity instantaneously, through a constant balance of supply and demand. The grid receives its electric current from electricity generation and in some cases from stored electricity through energy storage. In the simplest terms, energy generation controls time, from when and how we use it.

    Energy storage applications can fall into all portions of the grid and can be helpful as a way to improve the overall energy grid.

    Generation is where electricity is produced and energy storage applications can assist in various ways to ensure adequate electricity supply is available. Energy storage can supply energy when demand is larger than current supply, if there are any disruptions in traditional forms of generation, and at times when renewable resources are not generating electricity. One prime example of assisting in meeting demand is the use of storage during “peak,” where the demand reaches its highest point during the day. Rather than turn on a natural gas power plant to meet peak demand, storage applications can be used instead. Using storage in some cases can potentially reduce the carbon consumed or save in cost in some locations. In most cases, energy generation occurs far from population centers, which requires the generation to be transmitted across long distances.

    Transmission lines then carry the generated electricity to be distributed. Energy storage applications can help in the meantime to help relieve congestion, potentially deferring transmission upgrades, and can provide grid stabilization and maintain continuous power supply. Distribution to customers occurs after being converted to a lower voltage from the transmission lines. Energy storage applications can also apply in distribution to provide backup power in case of outages, for microgrids, and in reducing demand charges for customers by providing additional electricity during peak demand.

    The Origins of Energy Storage

    Energy storage as a technology has been around for almost a hundred years in the United States and Europe through pumped hydroelectric storage.2 Modern energy storage as we know it began in 1978 at Sandia National Lab through a program called “Batteries for Specific Solar Applications,” which focused on developing batteries along with other renewables.3 This program began shortly after the formal creation of the Department of Energy and was expanded quickly with a focus on batteries for electric vehicles. Over time, this program, now known as the Energy Storage Systems Program (ESSP) grew to include additional energy storage technologies such as flywheels and compressed air energy storage. While the ESSP initially began at Sandia National Lab, cross-collaborative research from materials science to demonstrations of energy storage technologies continues at Argonne National Lab, Oak Ridge National Lab, and Pacific Northwest National Lab. Research from these labs have continued to develop in the private sector, alongside separate private research and will continue to evolve over time.

    Types of Technologies

    Energy storage as a whole includes multiple technologies within chemical, mechanical, thermal, and kinetic energies. Chemical energy includes current batteries through chemical reactions within various battery types. Mechanical energy includes pumped hydro and compressed air energy storage. Thermal energy includes solar thermal power plants as well as heating and cooling objects by creating large temperature differences to store excess energy for later use. Flywheels are an example of kinetic energy.

    Lithium-ion Batteries

    Lithium-ion batteries range in chemistry composition, but all lithium-ion batteries transfer lithium-ions between their cathode and anode, where the cathode is usually a metal oxide and the most common anode is made up of graphite. Lithium-ion batteries can have a liquid electrolyte or a solid state electrolyte. Lithium-ion batteries have a lithium polymer where the electrodes are bonded together by a porous polymer matrix. This means the battery itself has a specific chemistry that varies, changing the battery’s capabilities. Depending on chemistry differences, there are benefits and concerns with each type as well as some being more successful than others. The benefits of lithium ion include: high energy density, less expensive, have long lifetime cycles, are rechargeable, have low maintenance, and have high rate discharge capability. Lithium-ion batteries have been successfully deployed in electric vehicles, mobile phones, and laptops. There is growth in research, design, and manufacturing for large scale projects for use in grid scale storage applications.

    Solid State Batteries

    Solid State Batteries have solid electrodes, cathodes, and anodes regardless of their chemistry. Basic chemistry varies in the types of solid state batteries, with three being very common: lithium-ion, nickel-cadmium, and sodium-sulfur. In addition to solid state lithium-ion batteries, other solid state batteries include those with the chemical compositions of nickel-cadmium and sodium-sulfur. Nickel-cadmium batteries are considered a traditional battery, meaning they remain a valid option to provide a long and reliable life cycle even when energy density and cost are not as great as lithium-ion. Nickel-cadmium batteries have been used successfully in grid scale storage as well for short duration use, and in island grid systems. Sodium-sulfur batteries are another stationary application with high efficiency. Japan has demonstrated this technology at multiple locations for six hour duration for peak shaving purposes.4 While both of these battery chemistries have been tested and deployed they are still not nearly as common as lithium-ion batteries, which currently dominate the market.

    Flow Batteries

    Flow batteries consist of a reversible chemical reaction, which occurs in multiple tanks. The electrodes are dissolved in electrolyte solutions stored in tanks – an anolyte tank containing an anode and a catholyte tank containing a cathode. These are pumped into cell stacks where the reversible reactions occur when the battery charges and discharges.5 There are two main flow battery systems: True flow or pure flow where all materials are stored separately from the cell and hybrid flow batteries where one or more of the active materials are stored within the cell.

    Flow batteries can also vary depending on the materials used for the chemical reaction in the electrolyte tanks. Flow batteries store energy in the liquid electrolyte tanks while traditional batteries store energy in their electrode materials. Flow batteries have high energy efficiency, long life cycles, can be long duration with fast response times as well as being capable of deep discharges. However, electrolyte stability is always a concern along with potential corrosion of materials.


    Flywheels are a very short duration form of energy storage that store energy by accelerating and braking a rotating mass – it’s connected to a reversible electrical machine that acts as a motor during charge that draws electricity from the grid to spin the flywheel up to a selected operating speed. The amount of energy that can be stored in a flywheel depends primarily on the momentum of inertia of the rotor (weight) and the speed at which it rotates. While flywheels have fast discharging capabilities, long life cycles, and no capacity degradation over time, they have low energy density, and can self-discharge. Overall flywheels would be best for frequency stabilization in the power grid rather than medium or long duration storage.

    Compressed Air Energy Storage

    Compressed Air Energy Storage or CAES stores energy in the form of compressed air in an underground reservoir for use at a later time. CAES is very similar to pumped hydro power in storage concepts, however, usage of the stored air is different than simply releasing water through a turbine. CAES systems release the pressurized air by heating it in order to expand it, which then turns a turbine, generating electricity.6 This is done through two systems – diabatic or adiabatic. Diabatic systems are really hybrid systems, where natural gas is used to heat the compressed air, resulting in expansion and a way for the turbine to generate electricity. Adiabatic systems do not use natural gas to reheat the air in the expansion process, rather the excess heat is stored above ground for future use when the air is meant to be expanded. Currently, only two CAES diabatic grid scale systems exist, one in Alabama and one in Germany. CAES have several benefits, but ideally they work best in balancing energy, for greater integration of renewable energy, ancillary services for the grid such as regulation, black-start, and grid stabilization.

    Thermal Energy Storage

    Thermal energy storage takes excess energy and stores it in various materials, including rocks, cement, storage tanks, hydrogen, and in liquid air. This is really a transfer of energy into a material that is capable of storing the energy for a longer time frame instead of wasting the excess or less expensive energy. A great example of this is solar thermal water heating.

    Heating and Cooling of Materials

    Some promising industry experiments are focused on storing excess energy in the form of thermal energy in materials such as rocks. The temperature in these substances can be cold or hot as there is energy in both forms. Siemens is currently conducting an experiment in heating rocks with excess energy until it is needed at a later point, when it will be used to drive a steam turbine to generate electricity.7

    Traditional Pumped Heat Electrical Storage compresses and expands gas through tanks filled with crushed rocks. This is usually a closed circuit where the gas is connected between a compressor and expander heating and cooling the crushed rocks as needed to store or use energy.

    Hydrogen Energy Storage

    Hydrogen Energy Storage stores electrical energy in hydrogen through electrolysis. This means electricity is used for hydrogen production through a process called electrolysis where water molecules are split into oxygen and hydrogen ions. The oxygen is released and the hydrogen is stored in pressurized containers and can be used as a fuel to be burned in combined cycle gas fired power plants or re-electrified later through fuel cells.8

    Liquid Air Energy Storage

    Liquid Air Energy Storage stores energy through compressed and liquefied air. This works in three steps – charging occurs when electrical energy pulls air from the environment, cooling the air until it liquefies and is then stored in an insulated tank at low pressure until it is needed later. When the energy is needed, the liquid air is pulled from the tank and pumped to a higher pressure, where it evaporates and is heated, producing a high pressured gas that is used to turn a turbine.9

    Pumped Hydropower

    Pumped Hydropower uses gravity to turn a turbine. While this technology has been successful since the 1920s, it has been modified for additional uses such as underground pumped hydro, reservoir pumped hydro, and variable speed pumped hydro.10 In many cases, pumped hydropower is used as a form of baseload electricity generation because it is reliable and inexpensive. However, over time it has become much more complex, and can be used in various ways to help improve grid stability and even act like a “peaker plant,” used at times when peak energy demand is at its highest to help reduce consumption of natural gas in natural gas peaker plants through variable speed pump-turbines.

    Traditional pumped hydropower stores energy in an upper reservoir or one higher in elevation than a lower reservoir. When wanting to store energy, water is pumped to the higher reservoir for later use. To “discharge,” or use the stored energy, it is released to the lower reservoir to generate electricity by turning a turbine.

    Underground pumped hydropower uses two reservoirs as well, they are both underground. These can be in man made storage reservoirs, mines, or caverns as well. In this system, energy is pumped from the lower reservoir to the higher reservoir as it “charges” the system, and to generate electricity, the water is released from the higher reservoir to the lower reservoir.

    What role does Energy Storage play in the future

    The future of energy storage is very promising and will continue to evolve as new technologies are developed. As costs decrease and renewables continue to grow, energy storage may have a larger market share. Currently there are no federal energy storage policies or mandates, however, there are a few states with energy storage mandates or policies. State policies, wholesale market rules, retail rates, and technological innovations are expected to impact the future of energy storage as a whole.

    The Federal Energy Regulatory Commission (FERC) released Order 841’s “Final Rule” for storage participation to remove barriers for energy storage in capacity, energy generation, and ancillary services markets in February 2018. The purpose of the order is to increase competition within the markets while supporting resiliency of the power system.11 Current markets are very difficult for energy storage to fully participate due to regulations in various markets, limiting how and if storage could participate. Generally, storage was not being utilized and could not compete with less expensive resources as a stand alone option. With this Order, each Regional Transmission Organization (RTO) is required to create a participation model that opens up market participation for energy storage resources.

    As the RTOs create rules based on the requirements given by FERC, it will directly impact the value of energy storage in each market. Due to FERC Order 841, state mandates or proceedings, energy storage as a whole is difficult to predict, however, significant growth is expected in the market due to benefits and the evolution of electricity generation. Recent RTO filings will also impact how the storage space as a whole continues to move forward. This is due to each RTO’s unique plan to incorporate energy storage into the future. As things progress, each region will continue to develop uniquely based on how storage is viewed and how it is integrated will have significant impacts on storage developments and electricity markets as a whole. While this will be a learning curve for storage resources in the grid as a whole, each plan will allow the markets to be more competitive and adaptive to storage needs over time.

    New Promising Technologies

    As technology continues to improve and costs decline, there are several promising energy storage technologies that may become viable options in the next few years. Most of these technologies are simply adaptations of traditional or well-known energy storage technologies, but have been changed to reduce cost, reduce use of resources, or to increase energy efficiency for example. Several organizations have spurred out of the Department of Energy, universities, and think tanks all with a variety of funding from government grants or loans to foundation investments. Some interesting and promising technologies include storing energy in cement blocks as a way to mimic pumped hydro, an adapted version of subsurface pumped hydro, and liquifying air in a similar manner to compressed air energy storage.

    Accelerated Ocean Currents Show Crisis Is Getting Faster

    ORIGINAL REPORTING: The Known Unknowns For 100% Renewables

    The unknown costs of a 100% carbon-free future; State approaches to a 100% carbon-free future vary and while several costs remain unknown, some solutions are emerging.

    Herman K. Trabish, Sept. 3, 2019 (Utility Dive)

    Editor’s note: The value of distributed resources and the future balance between central station and distributed renewables continue to make the cost of a 100% future uncertain.

    Opponents claimed zero emissions mandates in Hawaii, California, Washington, Colorado, New Mexico and New York would drive up electricity rates, but ample evidence in today's falling renewables prices led to lawmaker approval. Now, utilities and policymakers are trying to determine what the full costs of a high renewables power system will ultimately be.

    But cost impact forecasts cannot be certain until technologies protecting reliability are in place, Washington and New York utilities told Utility Dive. In contrast, Colorado and New Mexico were able to use utilities' expectations of lower costs to bolster political support. There are still many unknowns about the mandates' costs, advocates acknowledged. But that is not a reason to prevent enacting them, they added.

    The six mandates share a goal of very high levels of renewables and much lower greenhouse gas emissions than any state has achieved today. But their policies differ in detail. Utilities in these states don't have definitive formulas for achieving the long-term goals or a final calculation of costs. The transition to a fully decarbonized U.S. power system using currently available technologies would cost $4.5 trillion, according June's Wood Mackenzie analysis. That could mean nearly $2,000 per U.S. household per year for 20 years. But it is uncertain how much of the cost would fall on shareholders, companies or customers. Although wind, solar, and storage will make up the bulk of California's high renewables power supply, the need for "firm" generation creates another unknown, Energy + Environmental Economics found…But renewables advocates say if leaders establish a vision, engineers and advocates will find the way to achieve it…” click here for more

    “…[Solar and wind energy are forecast to dominate America’s new generation in 2020, making up 76% of new generation] while coal and natural gas will dominate 2020 retirements with 85% of plant closures…[For the utilities engaged in the power sector transformation, this could be a big] economic opportunity…U.S. renewable energy prices continued falling fast in 2019, with wind and solar hitting new lows…Over the last decade, wind energy prices have fallen 70% and solar photovoltaics have fallen 89% on average…

    MONDAY’S STUDY: Details On The Risks In The Climate Crisis

    Climate risk and response: Physical hazards and socioeconomic impacts

    January 2020 (McKinsey and Company)

    In Brief

    After more than 10,000 years of relative stability—the full span of human civilization—the Earth’s climate is changing. As average temperatures rise, acute hazards such as heat waves and floods grow in frequency and severity, and chronic hazards, such as drought and rising sea levels, intensify. Here we focus on understanding the nature and extent of physical risk from a changing climate over the next three decades, exploring physical risk as it is the basis of both transition and liability risks. We estimate inherent physical risk, absent adaptation and mitigation, to dimension the magnitude of the challenge and highlight the case for action. Climate science makes extensive use of scenarios ranging from lower (Representative Concentration Pathway 2.6) to higher (RCP 8.5) CO2 concentrations. We have chosen to focus on RCP 8.5, because the higher-emission scenario it portrays enables us to assess physical risk in the absence of further decarbonization. We link climate models with economic projections to examine nine cases that illustrate exposure to climate change extremes and proximity to physical thresholds. A separate geospatial assessment examines six indicators to assess potential socioeconomic impact in 105 countries. The research also provides decision makers with a new framework and methodology to estimate risks in their own specific context.

    Key findings:

    Climate change is already having substantial physical impacts at a local level in regions across the world; the affected regions will continue to grow in number and size. Since the 1880s, the average global temperature has risen by about 1.1 degrees Celsius with significant regional variations. This brings higher probabilities of extreme temperatures and an intensification of hazards. A changing climate in the next decade, and probably beyond, means the number and size of regions affected by substantial physical impacts will continue to grow. This will have direct effects on five socioeconomic systems: livability and workability, food systems, physical assets, infrastructure services, and natural capital.

    The socioeconomic impacts of climate change will likely be nonlinear as system thresholds are breached and have knock-on effects. Most of the past increase in direct impact from hazards has come from greater exposure to hazards versus increases in their mean and tail intensity. In the future, hazard intensification will likely assume a greater role. Societies and systems most at risk are close to physical and biological thresholds. For example, as heat and humidity increase in India, by 2030 under an RCP 8.5 scenario, between 160 million and 200 million people could live in regions with an average 5 percent annual probability of experiencing a heat wave that exceeds the survivability threshold for a healthy human being, absent an adaptation response. Ocean warming could reduce fish catches, affecting the livelihoods of 650 million to 800 million people who rely on fishing revenue. In Ho Chi Minh City, direct infrastructure damage from a 100-year flood could rise from about $200 million to $300 million today to $500 million to $1 billion by 2050, while knock-on costs could rise from $100 million to $400 million to between $1.5 billion and $8.5 billion.

    The global socioeconomic impacts of climate change could be substantial as a changing climate affects human beings, as well as physical and natural capital. By 2030, all 105 countries examined could experience an increase in at least one of the six indicators of socioeconomic impact we identify. By 2050, under an RCP 8.5 scenario, the number of people living in areas with a non-zero chance of lethal heat waves would rise from zero today to between 700 million and 1.2 billion (not factoring in air conditioner penetration). The average share of annual outdoor working hours lost due to extreme heat and humidity in exposed regions globally would increase from 10 percent today to 15 to 20 percent by 2050. The land area experiencing a shift in climate classification compared with 1901–25 would increase from about 25 percent today to roughly 45 percent.

    Financial markets could bring forward risk recognition in affected regions, with consequences for capital allocation and insurance. Greater understanding of climate risk could make long-duration borrowing unavailable, impact insurance cost and availability, and reduce terminal values. This could trigger capital reallocation and asset repricing. In Florida, for example, estimates based on past trends suggest that losses from flooding could devalue exposed homes by $30 billion to $80 billion, or about 15 to 35 percent, by 2050, all else being equal.

    Countries and regions with lower per capita GDP levels are generally more at risk. Poorer regions often have climates that are closer to physical thresholds. They rely more on outdoor work and natural capital and have less financial means to adapt quickly. Climate change could also benefit some countries; for example, crop yields could improve in Canada.

    Addressing physical climate risk will require more systematic risk management, accelerating adaptation, and decarbonization. Decision makers will need to translate climate science insights into potential physical and financial damages, through systematic risk management and robust modeling recognizing the limitations of past data. Adaptation can help manage risks, even though this could prove costly for affected regions and entail hard choices. Preparations for adaptation—whether seawalls, cooling shelters, or droughtresistant crops—will need collective attention, particularly about where to invest versus retreat. While adaptation is now urgent and there are many adaptation opportunities, climate science tells us that further warming and risk increase can only be stopped by achieving zero net greenhouse gas emissions…
