    Economic Stimulus and Global New Energy

    How much will renewable energy benefit from global stimulus packages?

    1 December 2021 (International Energy Agency)

    “…[As of October 2021, approved] government spending on clean energy reached USD 480 billion. The USD 45 billion allocated to renewables – including electricity, heat and fuels (biofuels, advanced biofuels and biogas) – accounted for about 9% of announced public spending on clean energy. The majority of global clean energy stimulus is expected to be spent over 2021-2023…[Energy efficiency] received USD 144 billion, the greatest clean energy spending globally…The second most supported sector is public transport (USD 94 billion), followed by low-emission vehicles and charging infrastructure (USD 79 billion)…

    Of the spending on low carbon power, we expect solar PV to receive the largest amount, accounting for almost half of low-carbon electricity spending (USD 24 billion) and split between utility-scale and distributed PV. This stimulus money will mostly support already developed markets in China, Korea and the European Union to further accelerate investments. Nuclear power has received around USD 9 billion in public spending, followed by offshore wind and onshore wind…

    …[Hydropower, geothermal, bioenergy, biogas, and biofuels only received around USD 6.5 billion but low-carbon hydrogen got USD 30 billion because it is thought by many] governments to be the main fuel for decarbonising the hard-to-abate sectors…[A]lmost three quarters of public spending on clean energy was allocated in Europe, followed by the Asia Pacific region and North America…[The spending on] renewable electricity could mobilise USD 380 billion of additional private investment…[depending on] policies and implementation measures…with solar PV providing over 90% of this upside potential…” click here for more

    …To hit the U.N.’s emission reduction target of capping global warming at 2 degrees Celsius, annual global emissions will need to be reduced by 50% within the next decade…[and] renewable energy projects need to reach $5 trillion a year by 2030 to meet these emission targets…[Some financial services providers with a focus on sustainability] won’t put customer funds with banks that invest in the fossil fuel industry, a practice that is common among even private and commercial investment banks pledging to achieve ‘net-zero’ financing…” click here for more

    ORIGINAL REPORTING: California Regulators See Increased Value In Customer-Owned Resources

    CPUC Updates Distributed Resources Plan to Capitalize on Broad Benefits

    Herman K. Trabish, August 3, 2021 (California Current)

    California’s groundbreaking 2016 Distributed Energy Resources Action Plan will be updated to better align rising levels of clean local renewables with ratepayer and society interests, particularly air quality, climate resiliency, and economic opportunities in disadvantaged communities, the California Public Utilities Commission announced July 23.

    It is “mission critical” to bring clean distributed energy resources to “all customers, including disadvantaged customers,” Mathew Tisdale, executive director of think tank Gridworks, said. The hope is that the new Action Plan drives “real investment of time and energy.”

    Significant growth is expected from California’s rooftop solar and other distributed generation, storage, electric vehicles (EVs), time-varying rates, load management, demand response, and energy efficiency. The state leads the nation in rooftop photovoltaics and other behind-the-meter clean energy.

    The key goal of the DER Action Plan 2.0 plan is to coordinate electric sector policy, grid planning, affordability, load flexibility, market integration, and customer initiatives, the CPUC said. That will include coordination with the California Air Resources Board, the California Energy Commission, and the California Independent System Operator. The plan update’s goal was well-received.

    Southern California Edison “could not be more aligned” with the commission’s vision and goals, SCE Managing Director for State Regulatory Operations Shinjini Menon said. Utility-scale renewable are more economic, but developing the needed transmission will take time, “which means DER have to be part of the equation” to achieve the state’s policies.

    Earlier, accelerating DER activity was not coordinated through an overarching framework. The Action Plan 1.0 “connected the commission’s interdependent proceedings and initiatives, but this is a timely update for the expanding capabilities of DER,” Tisdale added… click here for more

    The Big Benefits From Pricing Carbon

    EIA analysis projects carbon fees would decrease U.S. carbon dioxide emissions through 2050

    Chris Higginbotham, November 17, 2021 (U.S. Energy Information Administration)

    “Carbon fees as high as $35 per metric ton could decrease U.S. energy-related carbon dioxide (CO2) emissions by as much as 19% compared to 2020 levels…[A U.S. Energy Information Administration analysis] projects that U.S. energy-related CO2 emissions would decrease the most in the first 5–10 years but decrease at a significantly slower rate beyond that period…

    …A carbon fee is a tax implemented on the sale of fossil fuels based on the amount of CO2 emissions those fuels generate. EIA considered three levels of carbon fees for its analysis, starting in 2023 at about $15, $25, and $35 per metric ton of CO2. The fees would grow by 5% each year through 2050…EIA projects that with about a $15 carbon fee (which would increase to more than $56 in 2050), U.S. energy-related CO2 emissions would decrease 13% by 2050 over 2020 levels. About a $25 carbon fee (more than $94 in 2050) would create a 17% decrease, and an approximate $35 carbon fee (almost $132 in 2050) would create a 19% decrease over the same period…

    …[C]arbon fees would have downstream effects on the energy sector beyond emissions…[E]xisting U.S. nuclear power capacity would be less likely to retire, while renewable energy capacity would increase more rapidly…” click here for more

    Monday Study – Energy Efficiency Vs. Long Duration Storage

    Optimal strategies for a cost-effective and reliable 100% renewable electric grid Sammy Houssainya) and William Livingood, 2 November 2021 (Journal of Renewable and Sustainable Energy)

    Abstract

    This paper explores cost-optimal pathways to 100% renewable power systems for the U.S. building stock. We show that long-duration misalignments of supply and demand, spanning from multi-day to seasonal timescales, present a dominant challenge that must be addressed to meet real-time 100% renewable targets. While long-duration misalignments can be addressed through energy storage, we show that alternative and readily available solutions that are more cost-effective should be considered first. Through a techno-economic analysis, we identify cost-optimal, region-dependent, supply-side, and demand-side strategies that reduce, and in some U.S. regions eliminate, the otherwise substantial capacities and associated costs of long-duration energy storage. Investigated supply-side strategies include optimal mixes of renewable portfolios and oversized generation capacities. Considered demand-side strategies include building load flexibility and building energy efficiency investments. Our results reveal that building energy efficiency measures can reduce long-duration storage requirements at minimum total investment costs. In addition, oversizing and diversifying renewable generation can play a critical role in reducing storage requirements, remaining cost effective even when accounting for curtailed generation. We identify regionally dependent storage cost targets and show that for emerging long-duration energy storage innovations to achieve broad adoption, their costs will need to compete with the decreasing cost of renewables. The findings of this research are particularly important given that most long-duration storage technologies are currently either uneconomical, geologically constrained, or still underdeveloped.

    Introduction

    Climate change concerns and falling costs of renewable energy technologies are driving increased interest in clean and sustainable sources of energy.1–5 Leveraging these trends, many U.S. states, cities, and municipalities are showing their commitment to reduce their environmental impact by developing plans to shift to 100% renewable energy sources.6–10 Long-term societal benefits of this shift toward sustainability include decreased electricity costs, local job creation, cleaner air, and reduced medical costs related to pollution and other effects of climate change.11 However, the most significant drawback of renewable sources is their inherent variability. Consequently, grid reliability is a major concern in an energy system where most of the electricity produced is from variable generation (VG) sources, such as wind and solar photovoltaics (PV).12

    Numerous studies have focused on understanding the role of energy storage in increasing grid reliability and balancing supply and demand in high VG penetration scenarios.13–18 To date, there is no consensus on the required energy storage capacity for operating and maintaining a 100% renewable energy portfolio.19–21 However, there is agreement among researchers that some energy storage is necessary to maintain a continuous power balance between a 100% VG supply and natural demand for electricity.22 Moreover, multiple energy storage solutions are likely to be required, with each system's unique characteristics being leveraged to address a specific grid challenge.22 For example, the fast response time of high-power flywheels and supercapacitors makes them inherently suited for regulating grid frequency. The higher energy densities of electrochemical storage well-position the technology for ramping and operating reserves. In contrast, larger-scale energy storage solutions, such as pumped hydro, compressed air, and hydrogen storage, will likely prove useful in addressing bulk energy management challenges given their economies of scale.23,24

    Current studies of VG penetration in power systems mainly focus on identifying strategies that minimize generation curtailment and maximize the economic value of renewable resources.25–30 Denholm et al. investigated storage duration requirements for 55% VG penetration scenarios on the Electric Reliability Council of Texas (ERCOT) grid system and concluded that 4 h of storage reduces curtailment to 8%–10% of variable generation.28 In a separate study, an 80% VG scenario on the ERCOT grid system was investigated, and results showed that storing or moving just 4-h of average system load could enable reliable operations while keeping renewable curtailment below 20%.29 Another study investigated the storage needs for substituting fossil fuel plants with renewables in ERCOT and concluded that above 25%–30% renewable energy penetration, significant energy storage capacity is needed.30 The primary objective function in this study was minimization of storage needs; hence, the minimization of the combined renewable and storage investment costs was not investigated. Moreover, these studies constrained the analysis to predefined curtailment limits; therefore, techno-economic tradeoffs between renewable curtailments and storage capacities were not considered. Finally, these studies do not consider the remaining 20% of renewable penetration needed to reach a 100% renewable target, which we show has the most significant impact on storage requirements and total investment costs to achieve the target.

    Several studies have focused on the value of long-duration energy storage in scenarios with high adoption of renewable energy sources.31–35 Shaner et al. investigated U.S. storage needs and concluded that above 80% renewable penetrations, seasonal misalignments in supply and demand would have to be overcome.31 Guerra et al. explored the value of seasonal storage for 83.5% renewable energy penetration in the western U.S. with an emphasis on power system operational benefits.32 The study concludes that 1-week of hydrogen storage could be cost-effective at US$1.8/kWh by 2025 [32]. Similar studies identified cost targets for long-duration energy storage technologies to compete against low-carbon sources, such as nuclear, and natural gas.33,34 Sepulveda et al. conducted an analysis for Texas and New England and concluded that long-duration energy storage costs must be less than $1/kWh to fully displace firm low-carbon generation technologies.34 It is important to note that the solution space in the mentioned studies is limited by their lack of consideration for supply-side strategies, such as excess generation capacity, and demand-side strategies, such as building load flexibility and permanent building energy efficiency investments. In addition, long-duration energy storage cost targets that compete against surplus renewable capacity and curtailment, in 100% renewable constrained formulations, are not identified in these studies.

    Through recent efforts by Cebulla et al., an extensive synthesis of 17 country-wide storage expansion studies in the literature was conducted for Europe, Germany, and the U.S.35 The study concludes that with increasing variable generation shares, energy storage power capacity requirements increase linearly, and the energy capacity increases exponentially. The study provides a good reference on general trends observed by recent research on the subject; however, their synthesis did not filter for energy storage requirements by imposed curtailment constraints, renewable generation mixes, or demand-side strategies. Moreover, their investigation did not account for U.S. regional implication on cost-effective 100% renewable power systems.

    In a recent study, Perez et al. explored the impacts of overbuilding PV generation and concluded that proactive curtailment enables lowest cost solutions;36 however, their analysis was constrained to PV curtailments only. In addition, their investigations are limited to a case study in the state of Minnesota. Through their investigations, they also consider supply side flexibility through a 5% gas generation allowance and show that this leads to major reductions in overbuilding PV.36 However, their investigations do not include load flexibility strategies in strict 100% renewable scenarios.

    The objective of this paper is to identify cost-optimal pathways to 100% renewable power systems for the U.S. building stock. Throughout the analysis, we focus on energy storage duration and capacity requirements that are necessary to achieve the target. In contrast to the current body of research, we consider regionally dependent opportunities and solutions that minimize total investment costs. In addition, our analysis removes renewable curtailment constraints that intend to maximize the economic value of VG resources. In doing so, we explore the tradeoffs of excess renewable generation capacity and associated curtailments on storage requirements and total investment costs. Furthermore, we consider readily available supply side and demand-side strategies that minimize total costs. Techno-economic investigations of demand-side strategies include building load flexibility and permanent building energy efficiency impacts. Building energy efficiency investments decrease the necessary renewable capacity, transmission capacity, and storage requirements; therefore, its impacts are threefold. We also consider the techno-economics of supply-side strategies such as oversizing VG sources and the diversification of renewable portfolios.

    To summarize, the following list succinctly reiterates the novel elements of this research that have not been explored or identified in the literature:

    1- We investigate a U.S. regional analysis of pathways to 100% renewable power at minimum total investment costs. In doing so, we identify cost-optimal and region-dependent strategies to reduce the otherwise dominant long-duration energy storage capacity requirements and associated costs.

    2- We identify the optimum regional investment priorities and associated breakdowns by energy resource assets to achieve the target. Our analysis considers readily available supply-side and demand-side strategies, and energy assets.

    3- We identify regionally dependent long-duration energy storage cost targets for emerging storage technologies. In contrast to published works, we identify long-duration energy storage cost targets needed to compete with oversizing of increasingly lower-cost renewable generation.

    4- We reveal that a combination of (1) optimally mixed renewable resources, (2) oversized generation capacities, and (3) building energy efficiency investments can eliminate the need for long-duration energy storage in some U.S. regions. This is particularly important given that most long-duration storage technologies are either geologically constrained or still underdeveloped.

    Our research also intends to demonstrate an overarching calculation methodology that can be leveraged by future site-specific studies of cities, states, municipalities, districts, and communities aiming to achieve cost-optimal 100% renewable status. We begin our discussions in Sec. II by describing the methods used to develop the baseline model and for modeling generation, energy storage, building energy efficiency, and building load flexibility. Our results are presented in Sec. III, and in Sec. IV we highlight the limitations of our research and discuss opportunities for future work…

    Conclusion

    The primary focus of this study was to understand cost-optimal pathways to 100% renewable power systems for the U.S. building stock. The U.S. DOE prototype building models and U.S. EIA survey data were used to simulate the demand of a collection of buildings that are representative of the U.S. building stock. Several climate zones spanning the U.S. were investigated to demonstrate regional trends and opportunities. Our analysis shows that the last 75%–100% of renewable penetration results in significant increases in long-duration energy storage capacities and costs. Through the analysis, we identified region-dependent supply-side and demand -side strategies that reduce, and in some cases eliminate, the otherwise dominant long-duration energy storage capacity requirements and associated costs. We show that for each U.S. region, a clear and unique optimum renewable portfolio exists that minimizes storage needs and total costs. The optimum renewable mix generally favors higher wind power allocations in colder climates and higher solar PV allocations in hotter climates. Our results reveal that cost-optimal renewable production factor range from 1.4 to 3.2, and optimal energy efficiency penetrations range from 52% to 68% savings, depending on the climate region. Therefore, the benefits of excess generation capacities and building energy efficiency measures are outweighed by their incremental investments. The cost-optimal renewable production factors and energy efficiency penetrations typically increases from hotter to colder regions.

    A long-duration energy storage cost sensitivity analysis was presented which identifies regionally dependent storage cost targets for emerging technologies. In contrast to published works, we identify long-duration energy storage cost targets needed to compete with oversizing of increasingly lower-cost renewable generation. Our results indicate that U.S. regions defined by CZ 2A, CZ 3B, and CZ 5B have long-duration energy storage installed capital cost targets of $43, $30, and $73/kWh, respectively. For CZ 4A and CZ 7, higher costs would still deem multi-day storage economical, given the pronounced misalignment challenges in colder climates. We reveal that a combination of (1) optimally mixed renewable portfolios, (2) oversized generation capacities, and (3) building energy efficiency investments can eliminate the need for long-duration energy storage for U.S. regions defined by CZ 2A, CZ 3B, and CZ 5B. The findings of this research are particularly important given that most long-duration storage technologies are currently either uneconomical, geologically constrained, or still underdeveloped.

    Stand Up To Protect The Planet

    Want to fight for climate action but feel daunted or powerless? Try this; The scale of the crisis is intimidating. But most people are already members of organizations – like our employers, universities, unions or religious groups – that are great avenues to fight for concrete climate results

    Tayo Bero, 23 November 2021 (UK Guardian)

    “…[M]uch of climate action rhetoric these days remains split between personal calls to action – such as recycling or cutting down on individual consumption – and calls for governments, corporations and international organizations to wind down fossil fuel production, switch to renewable energy on a mass scale and protect key ecosystems…[The scale of the crisis can make individual action] seem like a drop in the bucket…But there are ways to use the affiliations we already have to boost our collective voice…

    If you’re employed by a big corporation…[P]lan walkouts or join strike actions to push…[for] serious commitments to climate action such as reducing their consumption and switching to clean energy alternatives…[or push] employers to divest their pension and retirement savings plans from fossil fuel companies…If you’re a member of a labor union…[Form] climate change campaigns or sub-groups within larger campaigns…[Collaborate] with academics and environmental groups on research to identify and develop effective strategies for climate action…[or] draft environmental policies that call on the government and international organizations to take serious climate action…[or] form workplace environment committees…

    If you’re a student or member of faculty at a university, push to divest from fossil fuels, generate power on-campus, and commit to being carbon-neutral…[and] join in collective action…If you belong to a religious organization… push for community initiatives that help the environment, like building green infrastructure…[and ask] religious leaders to support bills and other political actions that address climate change, or press Congress directly to take climate action…” click here for more

    More New Energy Needed Now

    What ‘transition’? Renewable energy is growing, but overall energy demand is growing faster

    Weizhen Tan, November 3, 2021 (CNBC)

    “The world wants to “transition” away from fossil fuels toward green energy, but the difficult reality is this: Dirty fuels are not going away — or even declining — anytime soon…[The] global supply of renewables will grow by 35 gigawatts from 2021 to 2022, but global power demand growth will go up by 100 gigawatts over the same period…Countries will have to tap traditional fuel sources to meet the rest of the demand…

    Global electricity demand is set to rebound strongly, jumping by close to 5% this year and by 4% in 2022…[The amount of electricity generated from renewables will increase] by 8% this year and more than 6% in 2022…[But] renewables are expected to be able to serve only around half of the projected growth in global demand in 2021 and 2022…[The] amount spent on oil and gas has declined as prices collapsed in 2020 and the industry faced growing pressure to move away from dirty fuels. Total spending [fell below the 2019 level in 2021 to] a little more than $350 billion…

    Transition-related spending is gradually picking up, but remains far short of what is required to meet rising demand…[and that] shortfall will only widen as economies reopen and travel resumes…[and lead to] sharp rises in prices for natural gas, coal and electricity…[Getting the world on track for net-zero emissions by 2050] would require clean energy transition-related investment to accelerate from current levels to around $4 trillion annually by 2030…That would mark an increase of more than three times the current investment… click here for more
