PSUT Names

psut_names.Rmd

Introduction

The prep_psut() function creates matsindf-style data frames of matrices. Each matrix has character strings for row and column names. The row and column names follow strict conventions. This vignette documents those conventions.

Rules

The rules for the row and column names are given below:

  1. All row and column names consists of a base part (the noun) and metadata (usually in the form of prepositional phrases)
  2. The base (noun) always matches the type of thing on that margin. E.g., if “Stock changes [of Crude oil]” is a row name in the make (V) matrix, the base part (“Stock changes”) is an industry, as all row names in V denote.
  3. The metadata are separated from the base by the strings “[” and ”]”.
  4. The metadata can include any number of prepositional phrases. In the example above, “of Crude oil” is metadata that modifies the base name (“Stock changes”)
  5. Each prepositional phrase consists of a single-word preposition and its (possibly multi-word) object.
  6. Prepositions can be one of “of”, “in”, “into”, “from”, “to”, and “->”. (Note that “->” indicates the outflowing product, a concept for which there is no good preposition in the English language.)

Matrices

R matrix

Rows

The R matrix has industries (resources) in rows. All row names in the R matrix have the same form:

  1. Resources: “Resources [of primary_product]”, where primary_product is a primary energy carrier. Example: “Resources [of Crude oil]”. With country: “Resources [of Crude oil in SAU]”.

Columns

The R matrix has products (energy carriers) in columns. All column names in the R matrix have the same form:

  1. Primary products: “primary_product [from Resources]”, where primary_product is a primary energy carrier. Example: “Crude oil [from Resources]”. With country: “Crude oil [from Resources in SAU]”.

V matrix

Rows

Like the R matrix, the V matrix has industries (processing stages) in rows. There are several options for names of rows in the V matrix.

  1. Imports: “Imports [of product]”, where product is a primary or final energy product. Example: “Imports [of Crude oil]”. With country: “Imports [of Crude oil into USA]”.
  2. Stock changes: “Stock changes [of product]”, where product is a primary or final energy carrier. Example: “Stock changes [of Crude oil]”. With country: “Stock changes [of Crude oil in SAU]”.
  3. Transformation processes: “pf_machine”, where pf_machine is a machine that converts primary energy to final energy. These data come from the IEA’s extended energy balances. Example: “Oil refineries”. With country: “Oil refineries [in SAU]”.
  4. Statistical differences: “Statistical differences” which originate from the IEA’s extended energy balances. Example: “Statistical differences”. With country: “Statistical differences [in SAU]”.
  5. Manufacture processes: “Manufacture [of product]”, where product is any energy carrier. These processes are inserted to convert Resources into primary products. Example: “Manufacture [of Hydro]”. With country: “Manufacture [of Hydro in ISL]”.
  6. Final-to-useful machines: “fu_machine -> useful_product”, where fu_machine is the name of a machine that converts final energy into useful energy and useful_product is the name of a useful energy product. Example: “LPG stoves -> MTH.200.C”. fu_machine [-> useful_product] With country: “LPG stoves [-> MTH.200.C in GHA]”.

Columns

Like the R matrix, the V matrix has products (energy carriers) in columns. There are two options for names of columns in the V matrix.

  1. Primary and final energy carriers: “product” where product is the unmodified name of the energy carrier in the IEA extended energy balances. Example: “Anthracite”. With country: “Anthracite [in AUS]”.
  2. Useful products: “useful_product [from fu_machine]”, where useful_product is a useful energy carrier and fu_machine is a final-to-useful machine. Example: “HPA [from Air compressors]” With country: “HPA [from Air compressors in USA]”.

U matrix

Rows

The U matrix has products (energy carriers) in rows.

  1. Resource flows: “primary_product [from Resources]”, where primary_product is a primary energy carrier. Example: “Biogasoline [from Resources]”. With country: “Biogasoline [from Resources in USA]”.
  2. Primary and final energy flows: “product”, where product is a primary or final energy carrier. Example: “Electricity”. With country: “Electricity [in GBR]”.
  3. Useful products: “useful_product [from fu_machine]”], where useful_product is a useful energy carrier and fu_machine is a final-to-useful machine. Example: “HPL [from Electric pumps]”. With country: “HPL [from Electric pumps in ESP]”.

Columns

The U matrix has industries (processing stages) in columns.

  1. Primary-to-final machines: “pf_machine” where pf_machine is the name of a primary-to-final machine. Example: “Blast furnaces” With country: “Blast furnaces [in USA]”.
  2. Final-to-useful machines: “fu_machine -> useful_product”, where fu_machine is a final-to-useful machine and useful_product is a useful energy carrier. fu_machine [-> useful_product] With country: “Ammonia synthesizers [-> HTH.400.C in POL]”.

Y matrix

Rows

Like the U matrix, the Y matrix has products (energy carriers) in rows.

  1. Primary and final products: “product”, where product is the unmodified name of the energy carrier in the IEA extended energy balances. Example: “Naptha”. With country: “Naptha [in ESP]”.
  2. Useful products: “product [from fu_machine]”, where product is a useful energy carrier and fu_machine is a final-to-useful machine. Example: “RoP [from Electric cars]”. With country: “RoP [from Electric cars in USA]”.

Columns

Like the U matrix, the Y matrix has industries (final demand sectors) in columns.

  1. Sectors: “sector”, where sector is the name of a final demand sector, unmodified from the IEA extended energy balances. Example: “Construction”. With country: “Construction [in USA]”.
  2. Exports: “Exports [of product]”, where product is a primary or final energy product. Example: “Exports [of Coking coal]”. With country: “Exports [of Coking coal from USA]”.
  3. Exports to World marine/aviation bunkers: “Exports to World bunker_type bunkers [of product]”, where bunker_type is either “marine” or “aviation” and product is a (typically) final energy product. Example: “Exports to World marine bunkers [of Biodiesels]”. With country: “Exports to World marine bunkers [of Biodiesels from USA]”.
