  • Please rename it to "water pipeline HDPE", i.e. that the name reflects broader category -> diameter -> material details. So some of the info that you put in the details should also go into the name

  • Can you add the figure where you extracted the data from in the report? (Probably figure 4-7?) and the date when you accessed the publication.

  • The currency year should be 2022 instead of 2023, can you confirm/check?

  • Are there any insights about the technology year of this data, whether this is from 1981 (like the pump station data)? Else we can keep it as 2023

Similar points as for the technology above:

  • rename to something like "water pipeline booster pump"
  • Exact location where the info is taken from the publication (I couldn't locate the origin of the data from the pub)
  • It seems like the publication uses a formula with a scaling exponent != 1, so if you make an assumption on the HP of the pump, add this assumptions and ideally also the calculation to the details.
  • Check technology (1981?) and currency year (2022)

Hi @doneachh and @euronion . I was the one working on this for the PR. So the source of the costs come from the formula (17) in : https://hypat.de/hypat-wAssets/docs/new/publikationen/HYPAT_WP_Water-Supply-for-Electrolysis-Plants.pdf

And the original sourcce of the formula comes from this report: https://www.countyofmonterey.gov/home/showdocument?id=18882

Where the 15570 USD are from 1981. So I used this formula to convert this number with a constant inflation of 2%:

Pump investment in millions Eur

invest_pumping_station = pump_station_cost_kw(
    power_kw=power_kW,
    usd_to_eur=snakemake.params.costs["default_exchange_rate"],
    a=35768, # 15570 # 35768 with inflation 2% 1981 till 2023
    b=0.558,
)

And the pump_station_cost_kw function is:

def pump_station_cost_kw(power_kw, usd_to_eur, a=35768, b=0.558):

Calculate pump station investment cost from installed power in kW.

Parameters:
-----------
power_kw : float or array
    Installed pump power in kW.
a : float
    Cost factor in Eur/HP (default 35768). Source: Inflation a2023=15570(1.02)**42≈35,768 USD/HP in https://hypat.de/hypat-wAssets/docs/new/publikationen/HYPAT_WP_Water-Supply-for-Electrolysis-Plants.pdf).
b : float
    Scaling exponent (default 0.558) Source: 1+b = 1-0.442 in https://hypat.de/hypat-wAssets/docs/new/publikationen/HYPAT_WP_Water-Supply-for-Electrolysis-Plants.pdf).
usd_to_eur : float
    Conversion rate from USD to EUR .

Returns:
--------
cost_eur : float or array
    Pump station cost in million EUR.

# Convert kW to HP
power_hp = power_kw / 0.7457

# Cost formula in USD
cost_usd = a * (power_hp ** b)

# Convert to EUR
cost_eur = cost_usd * usd_to_eur

# Return cost in million EUR
return cost_eur / 1e6

So technology (1981) and currency year (2023)

Efficiency is not clear for this technology.

Minimum: Add to the details what the efficiency unit is
Ideally: Change the unit to something more clear, maybe m3 water per kWh or something?

Hi @euronion . The efficiency here is taken from the same source by multiplying the motor efficiency wiith the pump efficiency: 0.85 x 0.9=0.765

Image

I guess we can consider the unit to be m3 water per kWh
