That focuses upon (but is not limited to) the rapidly growing needs of AI\/data centers.&nbsp; An approach, previously known as cogeneration and combined heat and power (CHP) gained popularity beginning in 1978 with the passage of PURPA. Great technology, bad policy.[1]<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">CHP technologies under the Biden Administration have lost favor given the myopic fixation upon establishing an energy monoculture via renewables, with all electricity and the electric grids necessary to deliver this fantasy. Customer-sited supply is taking a backseat.&nbsp; Recent estimates, just for the U.S., and just for storage batteries places the total costs of this transition in the range of multiples of the world GDP.&nbsp; These costs could double if the unlikely objective to \u201celectrify everything\u201d takes hold.

Certainly, there are many more energy end-use examples that could likewise benefit from diversity.&nbsp; Unfortunately, at present, diversity has become a priority of the Biden Administration for everything except energy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Doing the Math<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.eia.gov\/energyexplained\/electricity\/electricity-in-the-us.php#:~:text=In%202022%2C%20total%20U.S.%20utility,4.24%20trillion%20kilowatthours%20(kWh)\">According to the U.S. Energy Information Administration:&nbsp;<\/a>\u201cIn 2022, total U.S. utility-scale electricity generation was about 4.24 trillion kWh.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">4.24 trillion kWh = 4.24 \u00d7 10<sup>12 (<\/sup>1,000,000,000,000) = 4,240,000,000,000 kWh<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">4% of 4,240,000,000,000 kWh = 169,600,000,000 kWh\/year (2022 electric consumption of data centers)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">169,600,000,000 kWh\/year \u00f7 2,700 data centers = 62,814,815 kWh\/year per data center. Assuming 8,760 hours per year of base-loaded operation, this equates to 7,170.64 kW (or 7.17 MW ) of demand.<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">This demand puts average data centers in the technology range of aero-derivative gas combustion turbines (a.k.a. CT\u2019s; e.g.,&nbsp;<a href=\"https:\/\/www.solarturbines.com\/en_US.html\">Solar Turbines<\/a>) and\/or an array of VERY large reciprocating internal combustion engines (RICE; e.g.,&nbsp;<a href=\"https:\/\/www.jenbacher.us\/en\/our-gas-engines?utm_campaign=NAM-Branded-BMM__Jenbacher&amp;utm_source=google&amp;utm_medium=cpc&amp;utm_term=%2Bjenbacher%20%2Bj920&amp;utm_content=adgroup-114228234380__creative-481829248468__network-g__placement-__adposition-__matchtype-b__device-c&amp;gad_source=1&amp;gclid=Cj0KCQjwn7mwBhCiARIsAGoxjaILyKOinPDW16iacVDBDlBhZDHMLs1hGI9ORz5dGdf4bVrn3Aop4p0aApoYEALw_wcB\">Jenbacher<\/a>&nbsp;or&nbsp;<a href=\"https:\/\/www.cat.com\/en_US\/products\/new\/power-systems\/electric-power\/gas-generator-sets.html\">Caterpillar<\/a>). The latter (RICE) alternative may provide more economical redundancy by having at least one more \u201cgenset\u201d than needed to meet peak demand in times of scheduled (maintenance) or unscheduled outages.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At present, it is common practice to install diesel-fueled generators for emergency backup.&nbsp; Therefore, it is a manageable incremental cost to upgrade to continuous duty-rated natural gas engines and use them as such for CHP.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Since every kWh of data center CPU\/GPU electricity consumption use produces 3412 Btu\u2019s of heat energy, that heat must be removed to safeguard equipment and operations.&nbsp; Consequently, a significant portion of the electricity used in AI and data centers is for large tonnage electric motor driven centrifugal chillers to deal with internal heat gain from electric operated computing devices (etc.).&nbsp;In this analysis we are taking a&nbsp;<a href=\"https:\/\/docs.digital.ai\/bundle\/agility-onlinehelp\/page\/Content\/Digital.ai_Agility\/What_is_Swag.htm#:~:text=Swag%20stands%20for%20Scientific%20Wild,is%20estimated%20by%20an%20expert.\">SWAG<\/a>&nbsp;that 25% of the total 7.17 MW load is for cooling equipment to deal with such internal&nbsp; heat gains.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Such cooling loads can be at least partially offset through engine heat recovery absorption chillers (e.g.,&nbsp;<a href=\"https:\/\/broadusa.com\/broad\/\">Broad USA<\/a>,&nbsp;<a href=\"https:\/\/www.hitachiaircon.com\/range\/absorption-chiller\">Hitachi<\/a>,&nbsp;<a href=\"https:\/\/www.carrier.com\/commercial\/en\/eu\/products\/air-conditioning\/absorption-chillers\/\">Carrier<\/a>, etc.).&nbsp; Conversely, heat from engines in this size range can power steam boilers, that can be coupled to electric generators to make even more electricity.&nbsp; Even still, there is ample excess heat to power absorption chillers. In any case, installing heat recovery absorption chillers instead of electric motor-drive centrifugal chillers substantially lowers the added investment for absorption alternatives.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&nbsp;Simply assuming a cooling load of 7,171kW times 3,412 Btu\u2019s per kilowatt hour then divided by 12,000 Btu per ton-hour equates to 2,039 tons of refrigeration for a typical or average data center. But that\u2019s&nbsp;<strong>not&nbsp;<\/strong>just for the CPU\/GPU load.&nbsp; There is also some internal heat&nbsp;gain from lighting fans, people, etc., but that\u2019s probably not much relative&nbsp;to CPU\/GPU load from pushing electrons through silicone.&nbsp; Let building designers thoroughly&nbsp;calculate cooling requirements. According to Broad USA, their heat recovery absorption chillers operate at an average of 140 % efficiency (i.e., a&nbsp;<a href=\"https:\/\/en.wikipedia.org\/wiki\/Coefficient_of_performance\">C.O.P<\/a>. of 1.4) as long as the heat recovered meets their products\u2019 requirements as far as flow rate, temperature, etc., etc.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At this point, analyses become site\/application specific. To begin to conduct a proper feasibility study, a full 12 months of electric utility bills for an actual facility are needed and cooling load percentages factored in.&nbsp; With utility billing records in hand, a \u201c\u2019before &amp; after\u201d spreadsheet can be created that looks at utility billing impacts for a given facility operations with and without on-site generation and heat recovery absorption cooling systems.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To be meaningful, the spreadsheet should be based upon actual electric rate tariff sheets that the facility is billed on. If the analyst can replicate monthly utility bills based upon monthly demand and consumption, they are off to a good start to estimate savings potential. In addition to pecuniary savings, improvements in power quality and reliability from having generation on site should be evaluated.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One significant benefit of such an approach is the savings that accrue to other customers. As perfect power quality customers like data centers increase in number and demand, should the grid be designed and operated to meet their requirements and allocate those cost to all? Or should the power quality and reliability of the masses be met, and those with more stringent demands self-serve their nine-nines requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Of course, permitting such systems has become increasingly complicated.&nbsp; Therefore, it\u2019s important to use the services of knowledgeable experienced consulting engineers to develop plans and get them through permitting processes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Summary &amp; Conclusions<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Combined heat and power using waste heat recovery is a natural for AI\/data centers deserves more consideration. &nbsp;We hope that we have lit that spark. Whether that spark grows or not depends upon how permanently the Biden Administration has stifled market-based alternatives to renewables plus batteries via the \u201cInflation Reduction Act\u201d&nbsp; that strongly moves the market to higher and unsustainable levels of \u201cclean energy\u201d electrification.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The last of the additional references below indicates that there may be certain incentives for CHP through this Act, but we maintain that all such incentives are hidden taxes that are fueled by massive and ruinous deficit spending. Worse, there is no nexus between the subsidy levels and the value of CHP in specific cases. It is highly likely that some projects would see an excess level or insufficient level. We would be far better off as a society if everyone \u201cjust said no\u201d and the Federal government got out of the way of innovation instead of trying to manage it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Additional References<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AI\/data centers<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>January 2024:\u00a0<a href=\"https:\/\/www.nmrk.com\/storage-nmrk\/uploads\/documents\/2023-U.S.-Data-Center-Markets.pdf\">Numark 2023 U.S. Data Center Market Overview &amp; Market Clusters Report<\/a><\/li>\n\n\n\n<li>International Energy Agency<a href=\"https:\/\/www.iea.org\/reports\/electricity-2024\">: Electricity 2024 Analysis and forecast to 2026<\/a><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">On-site power generation<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.powermag.com\/the-line-blurs-between-small-cogen-plants-and-large-combined-cycles\/\">The Line Blurs Between Small Cogen Plants and Large Combined Cycles<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.ccj-online.com\/hrsgs-for-small-combined-cycle-and-cogen-plants\/\">HRSGs for small combined-cycle and cogen plants<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/consortia.myescenter.com\/CHP\/CHPA-IRA-FAQ-Updated-2024.pdf\">CHP AND WHP IN THE INFLATION REDUCTION ACT FREQUENTLY ASKED QUESTIONS<\/a><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2013<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Mark Krebs, a mechanical engineer and energy policy consultant, has been involved with energy efficiency design and program evaluation for over thirty years.
