EMR Additional Notes:

• Grid, Microgrids, DERs and DERM’s:
  • Grid / Power Grid:
    • The power grid is a network for delivering electricity to consumers. The power grid includes power generation facilities, substations, transmission lines and towers, distribution networks, protection and control equipment, and associated communication and monitoring infrastructure.
      • The grid continuously balances electricity generation and consumption while maintaining system stability and power quality, supplying electricity for applications ranging from industry to household appliances.
      • Electric grids perform three major functions or stages of electricity supply: power generation, transmission, and distribution. Grid operation also includes functions such as system balancing, protection, control, monitoring, and, increasingly, energy storage and demand-side management.
  • Microgrid:
    • A microgrid is a group of interconnected loads and distributed energy resources (DERs) within clearly defined electrical boundaries that acts as a single controllable entity with respect to the main grid and can operate either connected to the main grid or, when appropriately designed, intentionally and controllably in an islanded mode.
      • Microgrids can integrate local generation, energy storage, controllable loads, and other DERs to improve resilience, flexibility, efficiency, or local energy management.
  • Smart Grid:
    • A smart grid is an electrical grid enhanced with digital communications, sensing, automation, control, and data/analytics technologies across generation, transmission, distribution, and/or customer-side systems to improve the monitoring, operation, efficiency, reliability, resilience, and flexibility of the power system.
  • Distributed Energy Resources (DERs): 
    • Distributed energy resources (DERs) are relatively small-scale electricity generation, storage, and flexible demand resources, located at or near the distribution system or customer premises, that can supply, store, or modify electricity consumption and are interconnected to the electric grid. They are often located close to load centers and can be used individually or in aggregate to provide value to the grid.
      • Common examples of DERs include rooftop solar PV units, small wind turbines, small gas-fired generators or engines/turbines, microturbines, biomass generators, fuel cells, combined heat and power (CHP) or tri-generation systems with electrical generation, battery storage, electric vehicles and controllable EV charging or discharging where they can provide grid flexibility, and demand response applications.
  • Distributed Energy Resources Management Systems (DERMS):
    • Distributed Energy Resources Management Systems (DERMS) are software platforms that help utilities, distribution system operators (DSOs), aggregators, and other energy-sector organizations monitor, provide visibility into, forecast, coordinate, optimize, and, where supported, control distributed energy resources (DERs).
      • DERMS can be used to aggregate and coordinate large numbers of DERs and flexible loads for grid services, including voltage and power-flow management, congestion and constraint management, balancing, flexibility services, resilience, and participation in demand-response or other electricity markets. DERMS can be defined in many ways, depending on the use case, the types of DERs being managed, the responsibilities of the organization using the system, and the architecture of the power system.

 

 

 

• Industrial Automation:
  • Industrial Automation (umbrella term) is the use of technologies such as computer software and robotics to control machinery and processes which replace human beings in performing specific functions. The functions are primarily centered on manufacturing, quality control and material handling processes.
    • Process Automation / Manufacturing:
      • Process automation (based on the nature of the raw materials and final product) is defined as the use of software and technologies to automate business processes and functions in order to accomplish defined organizational goals, such as producing a product, hiring and onboarding an employee, or providing customer service.
      • Process manufacturing utilizes chemical, physical and compositional changes to convert raw material or feedstock into a product. Process manufacturing includes industries such as cement and glass, chemicals, electric power generation, food and beverage, life sciences, metals and mining, oil and gas, pulp and paper, refining, and water and wastewater. Process manufacturing includes both continuous and batch processes.
    • Discrete Automation / Manufacturing:
      • Discrete automation (focusing on individual, quantifiable parts and products) is the production of parts that are of a quantifiable nature. That may include cell phones, soda bottles, automobiles, airplanes, toys, etc. As you know, an automobile contains many, many parts. The parts required for an automobile are also quantifiable in nature.
      • Discrete manufacturing processes include the production of individual parts as well as their assembly into a final product. Discrete manufacturing examples include automobiles, appliances, and consumer electronics.
  • Types of Automation Systems (by flexibility):
    • Fixed Automation:
      • Most basic, least flexible type of automation, ideal for high-volume, unchanging production.
      • Fixed automation systems are utilized in high volume production settings that have dedicated equipment. The equipment has fixed operation sets and is designed to perform efficiently with the operation sets. This type of automation is mainly used in discrete mass production and continuous flow systems like paint shops, distillation processes, transfer lines and conveyors. All these processes rely on mechanized machinery to perform their fixed and repetitive operations to achieve high production volumes.
    • Programmable Automation:
      • Next level of flexibility, where the system can be reprogrammed, but with a significant effort.
      • Programmable automation systems facilitate changeable operation sequences and machine configuration using electronic controls. With programmable automation, non-trivial programming efforts are required to reprogram sequence and machine operations. Since production processes are not changed often, programmable automation systems tend to be less expensive in the long run. This type of system is mainly used in low job variety and medium-to-high product volume settings. It may also be used in mass production settings like paper mills and steel rolling mills.
    • Flexible Automation:
      • Most advanced type of automation based on flexibility, allowing for easy, high-level changes without major reprogramming.
      • Flexible automation systems are utilized in computer-controlled flexible manufacturing systems. Human operators enter high-level commands in the form of computer codes that identify products and their location in the system’s sequence to trigger automatic lower-level changes. Every production machine receives instructions from a human-operated computer. The instructions trigger the loading and unloading of necessary tools before carrying out their computer-instructed processes. Once processing is completed, the end products are transferred to the next machine automatically. Flexible industrial automation is used in batch processes and job shops with high product varieties and low-to-medium job volumes.
  • Advanced and Integrated Concepts (most complex):
    • Integrated Automation:
      • Takes flexible automation to the next level by explaining how an entire plant’s processes, from manufacturing to business operations, are linked under a single computer-controlled system.
      • Integrated industrial automation involves the total automation of manufacturing plants where all processes function under digital information processing coordination and computer control. It comprises technologies like:
        • Computer-aided process planning
        • Computer-supported design and manufacturing
        • Flexible machine systems
        • Computer numerical control machine tools
        • Automated material handling systems, like robots
        • Automatic storage and retrieval systems
        • Computerized production and scheduling control
        • Automated conveyors and cranes
      • Additionally, an integrated automation system can integrate a business system via a common database. That is, it supports the full integration of management operations and processes using communication and information technologies. Such technologies are utilized in computer integrated manufacturing and advanced process automation systems.
    • Smart Manufacturing (SM):
      • Modern evolution of automation, driven by data and connectivity.
      • Technology-driven approach that utilizes Internet-connected machinery to monitor the production process. The goal of SM is to identify opportunities for automating operations and use data analytics to improve manufacturing performance.
      • An example of what the cloud can do for smart manufacturing is the Volkswagen Industrial Cloud, which combines all data from 122 Volkswagen Group facilities and processes it in real time to make improvements.
    • Hybrid Automation / Manufacturing:
      • Combines different approaches, showing how both additive and subtractive manufacturing can be integrated into one process. It also introduces the “hybrid” method for implementing automation projects.
      • The Hybrid Automation Method follows two guiding principles: Implementing robust automation solutions that are easy and affordable for organisations to maintain. Realising process efficiency rapidly by reducing project overheads and time-to-value.
      • Hybrid manufacturing is a combination of additive manufacturing (AM) and subtractive manufacturing within the same machine.
    • Additive Manufacturing (AM):
      • Key technology of one of the core components of the “hybrid” approach.
      • Additive manufacturing is the process of creating an object by building it one layer at a time. It is the opposite of subtractive manufacturing, in which an object is created by cutting away at a solid block of material until the final product is complete.
      • Operators across a variety of different manufacturing industries utilize additive manufacturing in various ways. For instance: Medical device manufacturers use 3D printing to develop high variance products such as dental implants.
      • The term “additive manufacturing” refers to the creation of objects by “adding” material. Therefore, 3D printing is a form of additive manufacturing. When an object is created by adding material — as opposed to removing material — it’s considered additive manufacturing.

 

 

 

• Carbon Dioxide (CO2):
  • The primary greenhouse gas emitted through human activities. Carbon dioxide enters the atmosphere through the burning of fossil fuels (coal, natural gas, and oil), solid waste, biomass (e.g. wood), and also as a result of certain industrial chemical reactions (e.g. cement production).
  • Carbon dioxide is removed from the atmosphere (or “sequestered”) when it is absorbed by plants as part of the biological carbon cycle and through ocean absorption and geological processes. In climate accounting, however, “carbon sequestration” generally refers to the removal and storage of carbon in a reservoir; natural uptake through the carbon cycle is not necessarily classified as anthropogenic carbon dioxide removal (CDR).
  • CO₂ is naturally part of the carbon cycle, but human activities have significantly increased its concentration in the atmosphere.
• Biogenic Carbon Dioxide (CO2):
  • Biogenic CO₂ and fossil-derived CO₂ are chemically identical molecules.
  • The distinction is not chemical, but source-based:
    • Biogenic carbon: CO₂ released from organic materials such as plants, wood, soil, and biomass that were recently part of the natural carbon cycle. Its accounting treatment depends on the applicable carbon-accounting methodology and whether the carbon is considered part of the contemporary biogenic carbon cycle.
    • Fossil carbon: CO₂ released from fossil fuels (coal, oil, gas), which were stored underground for millions of years. This introduces additional carbon into the active atmospheric carbon cycle and is therefore generally treated as fossil CO₂ emissions.
• CO2e (Carbon Dioxide Equivalent):
  • CO₂e means “carbon dioxide equivalent”.
  • It is a standardized climate metric used to express the total climate impact of multiple greenhouse gases in a single standardized unit.
  • CO₂e converts all greenhouse gases (such as methane and nitrous oxide) into the amount of CO₂ that would have the same integrated radiative forcing / climate impact over a defined time period using a specified Global Warming Potential (GWP) value.
  • Formula: CO₂e = mass of gas × Global Warming Potential (GWP)
  • Carbon dioxide equivalents are commonly expressed as million metric tonnes of carbon dioxide equivalents, abbreviated as MtCO₂e or Mt CO₂-eq; “MMTCDE” is used in some datasets but is not the preferred general notation.
  • The carbon dioxide equivalent for a gas is derived by multiplying the tonnes of the gas by the associated GWP: CO₂e = mass of gas × GWP.
  • For example, the GWP for methane is approximately 27–30 under IPCC AR6 depending on the methane source and accounting convention, while the 100-year GWP for nitrous oxide is 273. This means that emissions of 1 million metric tonnes of methane and nitrous oxide respectively would correspond to approximately 27–30 and 273 million metric tonnes of CO₂e under those GWP assumptions.
• Carbon Footprint:
  • There is no universally agreed definition of what a carbon footprint is.
  • The most widely used definition (GHG Protocol) describes it as: “The total set of greenhouse gas (GHG) emissions caused directly and indirectly through an organization’s operations and value chain.” The GHG Protocol generally refers to corporate GHG inventories and Scope 1, 2 and 3 emissions rather than prescribing one universal definition of “carbon footprint.”
  • A carbon footprint is the total amount of greenhouse gas (GHG) emissions caused directly and indirectly by an individual, organization, product, or activity.
  • It is typically measured in CO₂e.
• Decarbonization:
  • Reduction of carbon dioxide emissions through the use of low-carbon energy sources and improved efficiency, with the goal of reducing overall greenhouse gas emissions. More broadly, decarbonization refers to reducing the carbon intensity and/or absolute greenhouse-gas emissions of an economy, sector, organization, product, or process, potentially including CO₂ removal for residual emissions.
  • Decarbonization typically refers to system-wide transition, not only emission reduction at a single source.
• Carbon Credits or Carbon Offsets:
  • Carbon credits are tradable certificates representing the verified reduction or removal of one metric tonne of CO₂e, generally generated by a specific project or activity; terminology and quality criteria vary between carbon markets.
  • They are part of cap-and-trade systems, where:
    • A cap limits total emissions
    • Companies receive or buy emission allowances
    • Excess allowances can be traded
  • Offsets are often linked to external projects that reduce or remove emissions (e.g. reforestation, renewable energy). A carbon offset is generally a credit representing a reduction or removal outside the entity’s own emissions boundary that may be used to compensate for emissions, subject to the applicable programme or claim rules.
  • Carbon credits and emission allowances should not be treated as synonymous: an allowance is a regulated authorization to emit under a cap-and-trade system, whereas a credit/offset generally represents a quantified emission reduction or removal.
• Carbon Capture and Storage (CCS) – Carbon Capture, Utilisation and Storage (CCUS):
  • CCS involves capturing CO₂ emissions from industrial processes or other concentrated sources and storing them permanently in geological formations (e.g. underground reservoirs).
  • CCUS adds a utilization step, where captured CO₂ is reused as a feedstock (e.g. fuels, chemicals, building materials). More precisely, CCUS refers to carbon capture followed by utilization and/or storage; utilization does not necessarily result in permanent carbon storage.
  • CCS = capture + geological storage; CCUS = capture + utilization and/or storage.
• Carbon Dioxide Removal (CDR) or Durable Carbon Removal: 
  • CDR refers to methods that actively remove CO₂ from the atmosphere and store it for long periods in geological, biological, or mineral form. CDR specifically requires an anthropogenic activity that removes atmospheric CO₂ and durably stores it in geological, terrestrial, ocean, or product reservoirs.
  • Examples include:
    • Direct Air Capture (DAC)
    • Bioenergy with Carbon Capture (BECCS)
    • Enhanced Rock Weathering (ERW)
  • CDR creates net negative emissions when removal exceeds emissions. A CDR activity itself can provide a net removal only when the total emissions associated with the removal process are lower than the amount of CO₂ durably removed and stored.
• Direct Air Capture (DAC): 
  • Technologies that extract CO2 directly from the atmosphere at any location, unlike carbon capture which is generally carried out at the point of emissions, such as a steel plant. DAC can capture CO₂ from ambient air regardless of where the original emissions occurred; it is distinct from point-source carbon capture.
  • Constraints like costs and energy requirements as well as the potential for pollution make DAC a less desirable option for CO2 reduction. Its larger land footprint when compared to other mitigation strategies like carbon capture and storage systems (CCS) also put it at a disadvantage. However, DAC is a potential carbon-removal technology rather than simply a CO₂-reduction technology, and its climate benefit depends strongly on the energy source, capture efficiency, permanence of storage, and lifecycle emissions.
• Direct Air Capture and Storage (DACCS):
  • Climate technology that removes carbon dioxide (CO2) directly from the ambient atmosphere using large fans and chemical processes to bind with the CO2. The captured CO₂ is then transported and durably stored, typically in geological formations.
  • DACCS is therefore a specific form of CDR: DAC + durable CO₂ storage.
• Bioenergy with Carbon Capture and Storage (BECCS):
  • Technology that generates energy from biomass while capturing and storing the resulting CO₂.
  • Because biomass absorbs CO₂ while growing, BECCS can result in net negative emissions. It can result in net negative emissions when the full lifecycle emissions—including biomass production, harvesting, transport, processing, energy use, and capture/storage—are sufficiently lower than the amount of biogenic CO₂ durably removed from the atmosphere.
• Enhanced Rock Weathering (ERW):
  • Carbon dioxide removal (CDR) technique that accelerates the natural process of rock weathering by grinding silicate rocks into dust and spreading it on land, typically agricultural fields. This process enhances reactions with water and atmospheric CO₂, converting dissolved carbon into bicarbonate and, ultimately, carbonate minerals or transporting dissolved inorganic carbon to aquatic systems, where it can be stored over long timescales.
  • Its effectiveness and permanence depend on rock type, particle size, weathering rates, transport pathways, soil and water chemistry, and the emissions associated with mining, grinding, and transporting the rock.
• Limits of Carbon Dioxide Storage: 
  • Carbon storage is not endless; the Earth’s capacity for permanently storing vast amounts of captured carbon, particularly in geological formations, is limited, potentially reaching a critical limit of 1,460 gigatonnes at around 2200, though storage durations vary significantly depending on the method, from decades for some biological methods to potentially millions of years for others like mineralization. Estimates of geological storage capacity vary widely and depend on geology, reservoir characteristics, storage efficiency, infrastructure, economics, regulation, monitoring, and permanence.
  • While some methods offer very long-term storage, the sheer volume needed to meet climate targets requires scaling up storage significantly beyond current capacity, raising concerns about the available volume over time. The practical constraint is therefore better described as the need to develop sufficient safe, permanent, economically and technically accessible storage capacity rather than a single known global physical limit.
• Carbon Impregnation: 
  • Carbon impregnation is the process of treating activated carbon with chemical agents (such as metals, acids, or bases) to enhance its ability to adsorb specific, hard-to-remove pollutants. By loading substances like silver, sulfur, or potassium hydroxide into its pores, this material combines physical adsorption with chemical reaction for improved, targeted filtration in water and air. This is a materials engineering process, not a climate accounting concept.

 

• Global Warming: 
  • Global warming is the long-term heating of Earth’s climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere. Global warming refers specifically to the long-term increase in Earth’s average surface temperature; climate change is the broader term encompassing associated changes in climate systems, including precipitation, extremes, sea level, and ecosystems.
• Global Warming Potential (GWP): 
  • A measure of how much heat a greenhouse gas contributes to climate warming relative to CO₂ over a specific time period (commonly 100 years).
  • CO₂ has a GWP of 1.
  • GWP is the scientific basis for converting gases into CO₂e.
  • GWP was developed to allow comparisons of the global warming impacts of different gases. The numerical GWP depends on the selected IPCC assessment, time horizon, and, for some gases such as methane, the emission source and accounting convention.
• Greenhouse Gas (GHG):
  • Any gas that absorbs and emits infrared radiation in the atmosphere, contributing to the greenhouse effect.
  • Main GHGs include:
    • CO₂
    • Methane (CH₄)
    • Nitrous oxide (N₂O)
    • Fluorinated gases such as HFCs, PFCs, SF₆ and NF₃
  • Water vapor is a GHG but is not directly controlled by human emissions at scale. It is primarily a feedback in the climate system rather than a direct target of conventional anthropogenic GHG inventories.

• GHG Protocol Corporate Standard Scope 1, 2 and 3: https://ghgprotocol.org/ + The GHG Protocol Corporate Accounting and Reporting Standard provides requirements and guidance for companies and other organizations preparing a corporate-level GHG emissions inventory. The Corporate Standard itself is voluntary, although companies may be required by applicable legislation or regulation to report using the GHG Protocol or equivalent requirements.
  • Scope 1: Direct emissions:
    • Direct emissions from company-owned and controlled resources. In other words, emissions are released into the atmosphere as a direct result of a set of activities, at a firm level. More precisely, Scope 1 covers direct GHG emissions from sources that are owned or controlled by the reporting organization.
    • It is divided into four categories:
      • Stationary combustion (e.g from fuels, heating sources). All fuels that produce GHG emissions must be included in scope 1. This applies when the combustion source is owned or controlled by the reporting organization.
      • Mobile combustion is all vehicles owned or controlled by a firm, burning fuel (e.g. cars, vans, trucks). The increasing use of “electric” vehicles (EVs), means that some of the organisation’s fleets could fall into Scope 2 emissions. For example, fuel combustion in an owned/controlled vehicle is Scope 1, whereas electricity purchased to charge an EV is generally Scope 2; an EV itself does not create Scope 2 emissions—the purchased electricity does.
      • Fugitive emissions are leaks from greenhouse gases (e.g. refrigeration, air conditioning units). It is important to note that refrigerant gases are not uniformly “a thousand times more dangerous” than CO₂; some refrigerants have GWPs of hundreds or thousands of times that of CO₂, while others have much lower values. Companies are encouraged to report these emissions.
      • Process emissions are released during industrial processes, and on-site manufacturing (e.g. production of CO2 during cement manufacturing, factory fumes, chemicals). These are direct emissions resulting from physical or chemical processes other than fuel combustion, such as calcination in cement production..
  • Scope 2: Indirect emissions – owned:
    • Indirect emissions from the generation of purchased energy, from a utility provider. In other words, all GHG emissions released in the atmosphere, from the consumption of purchased electricity, steam, heat and cooling. Scope 2 covers indirect GHG emissions associated with the generation of purchased or acquired electricity, steam, heat, and cooling consumed by the reporting organization; “owned” is therefore misleading because the emissions source is owned or controlled by another entity.
    • For most organisations, electricity will be the unique source of scope 2 emissions. Simply stated, the energy consumed falls into two scopes: Scope 2 covers the electricity consumed by the end-user. Scope 3 covers the energy used by the utilities during transmission and distribution (T&D) losses. More precisely, Scope 2 covers the generation-related emissions associated with purchased electricity, not the physical electricity itself. T&D losses are generally accounted for in Scope 3 Category 3 for an energy consumer that does not own the T&D system, although the treatment can vary depending on ownership and accounting circumstances.
  • Scope 3: Indirect emissions – not owned:
    • Indirect emissions – not included in scope 2 – that occur in the value chain of the reporting company, including both upstream and downstream emissions. In other words, emissions are linked to the company’s operations. According to the GHG protocol, scope 3 emissions are separated into 15 categories. Scope 3 therefore captures other indirect value-chain emissions, upstream and downstream, across the 15 defined categories of the Scope 3 Standard.

 

 

 

• CapEx vs. OpEx:
  • Capital expenditures (CapEx) are a company’s major, long-term expenses while operating expenses (OpEx) are a company’s day-to-day expenses.
  • Examples of CapEx include physical assets, such as buildings, equipment, machinery, and vehicles. Examples of OpEx include employee salaries, rent, utilities, and property taxes.

 

 

 

• Grinding:
  • Grinding is a multi-meaning term primarily referring to an abrasive machining process used to cut, shape, or finish materials using a rotating abrasive wheel.
