Puerto Rico Grid Resilience and Transitions to 100% Renewable Energy Study (PR100): Six-Month Progress Update

DOE and its national laboratories have provided Puerto Rico energy system stakeholders with tools, education, and modeling assistance to help plan and operate the electric power grid with greater flexibility against future disruptions since Hurricanes Irma and Maria in September 2017. The two-year Puerto Rico Grid Resilience and Transitions to 100% Renewable Energy Study, by DOE, FEMA, and six national laboratories, launched the two-year Puerto Rico Grid Resilience and Transitions to 100% Renewable Energy Study on February 2, 2022, to conduct a comprehensive analysis of stakeholder-driven paths to Puerto Rico's energy future.

Puerto Rico Grid Resilience and Transitions to 100% Renewable Energy Study (PR100): Six-Month Progress Update

DOE and its national laboratories have provided Puerto Rico's electricity grid planners with tools, education, and modeling assistance to help plan and operate the electric power grid with greater stability against further disruptions since hurricanes Irma and Maria in September 2017. The two-year Puerto Rico Grid Resilience and Transitions to 100% Renewable Energy Study, conducted by DOE, FEMA, and six national laboratories, on February 2, 2022, to conduct comprehensive research of stakeholder-driven pathways to Puerto Rico's energy future.

Intersections of Disadvantaged Communities and Renewable Energy Potential: Analyses to Inform Equitable Investment Prioritization

Renewable energy development and employment opportunities can often see lower rates of renewable energy deployment in communities in need of economic growth and jobs; however, local tax revenues, reduced energy prices, and reduced energy consumption can all help local economies. We searched for areas where indicators of minority groups intersect with high-generation potential from cost-effective renewable energy options.

Site demonstration and performance evaluation of MPC for a large chiller plant with TES for renewable energy integration and grid decarbonization

A cooling plant's thermal energy storage capacity is a key component of load flexibility. However, the increasing use of renewables alters the situation, leading to the consumption of more electricity in the daytime and a volatile renewable generation that neces dynamic planning. Diversetting greenhouse gas emissions reduces the possibility of cooling TES plant operations, as different control strategies can be used to optimize operations for energy cost or carbon reductions. This paper presents a model predictive control, site demonstration, and evaluation results of the most effective operation of a chiller plant, TES, and behind-meter photovoltaics for a campus-level district cooling scheme. The MPC results show reductions of excess PV power by around 25%, of the greenhouse gas emission reductions by 10%, and peak electricity demand by 10%, relative to baseline rule-based controls.

Integrating renewable energy into mining operations: Opportunities, challenges, and enabling approaches

Mining is one of the world's most energy-intensive industries. As the world population increases and many low-income countries become middle-income countries, demand for raw materials is expected to rise. Mineral demand, as well as decreasing mineral ore quality, could potentially raise the mining industry's energy demand, which is used for mining, extraction, refinery, and refining. Mining could use energy recovery, renewable energy, and carbon capture to augment, replace, or minimize the impacts of fossil fuel use in principle. By reviewing the literature, including academic research, scientific papers, and data collected by international agencies, we explore the risks, opportunities, and enabling approaches to incorporate renewable energy sources into mining operations. Further research should examine specific opportunities, technologies, and adoption plans throughout a variety of minerals with similar processing procedures.

Techno-economic analysis of long-duration energy storage and flexible power generation technologies to support high-variable renewable energy grids

Clean power systems will require long-duration energy storage or flexible, low-carbon generation as variable renewable energy penetration rises above 80%. Hydrogen systems with geologic storage and natural gas capture, as well as future capital expenditures for both current and future capital requirements, are shown in this report. These findings are robust to uncertainty regarding the future capital cost scenario, but adiabatic compressed air and pumped thermal storage may be the least-cost options in the current capital cost scenario under uncertainty.

Voluntary Renewable Energy Procurement Programs in Regulated Utility Markets

The potential of global corporate RE purchases has been forecast to be nearly 100 GW and increasing; however, several markets still lack supportive infrastructure for corporations to access RE via on-site project development or private sector transactions. Utility green tariff plans, as well as renewable energy certificates in this article, provide competitive market-based services to retailers, regulators, and policymakers in order to provide corporate and other customers with RE product choices while still raising funds to support RE development. GPPs use RECs, which are a sort of energy attribute certificate and closely resemble guarantees of origin, to monitor and ultimately monetize RE attributes that companies and other customers must obtain in order to demonstrate compliance against their RE obligations and make public statements of use of RE.
