AI Summary
Summary
The author compares Bloom Energy (BE) and Capstone Green Energy (CGRN) for powering data centers, arguing Capstone’s turbine technology is superior for cooling and undervalued.
Thesis: Capstone (OTC, ~$310M market cap) solves the data center power/cooling bottleneck better than Bloom, trading at a fraction of Bloom’s valuation (2.8x vs 31x sales) with a catalyst from recent capital infusion and planned exchange listing.
Quality assessment: This is a well-researched, detailed deep dive with specific technical comparisons, financials, and a recent catalyst (Monarch capital); not speculation.

Bloom Energy trades at $63 billion on $2 billion in revenue. The market figured out that on-site power cells can get a data center online in 90 days while the grid takes 4-7 years. It was a Simple thesis that led to an enormous re-rating.
But a data center doesn't just need watts. It needs **cooling**. Cooling is 30-40% of total facility power consumption. Increasingly, date centers try and convert waste heat from power generation into cooling via absorption chillers, to reduce costs. This is where the comparison gets interesting.
Take a 10MW compute data center. Cooling needs roughly 6.67MW assuming compute is 60% of power and cooling is 40 of that 60.
**With Capstone:** 30.3MW of gas input(33% electrical efficiency). Their C1000S recovers 50% of fuel input as thermal energy, giving 15.2MW thermal. At a COP of 0.7, that's 10.64MW of displaced cooling, or 160% of the cooling load. Zero additional grid draw needed for cooling.
**With Bloom:** 15.4MW of gas input(65% electrical efficiency). At 36% thermal efficiency, that's 5.5MW thermal. At COP 0.7, that's 3.85MW of displaced cooling. 57.7% of the cooling load. **2.82MW still needs to come from the grid per 10MW of compute.**
*Grid interconnection queues in the US exceeded 1,500GW in 2025*. **Half** of all planned 2026 data centers are cancelled or delayed due to a pure lack of power. **Every MW pulled from the grid for cooling is a MW not used for compute.** Bloom perpetuates this problem. Capstone eliminates it.
A few other things worth knowing:
Bloom's fuel cells degrade 5% annually in output. Capstone's air bearing turbine has a single moving part and requires maintenance only every 8,000 operating hours. Capstone is significantly cheaper on upfront capex.
So why hasn't anyone noticed? Capstone went through Chapter 11 in late 2023, got delisted to OTC, and underwent an SEC investigation and financial restatement simultaneously. Most institutions structurally can't own OTC securities. Capital starvation froze their fleet expansion. Goldman's post restructuring preferred equity structure meant every share they issued to raise capital made Goldman's economic interest larger as a percentage of enterprise value. The constraints were real, but they were structural, not fundamental. **But things have changed.**
Two weeks ago Monarch Alternative Capital deployed $112.5M to fully redeem Goldman's preferred interest and fund fleet expansion. Management **personally co-invested** in both the November 2025 and March 2026 PIPEs. Monarch committed to filing for a national exchange listing within 12 months. At $6.27, fully diluted market cap is $310M on $110M projected revenue and $16-17M projected EBITDA. 2.8x P/S and 18x EV/EBITDA, priced as a hardware manufacturer while FPP(services) margins expanded from 41% to 88% in two years and rental utilization sits at 98%. Bloom trades at 31x sales. Capstone trades at 2.8x. All whole Capstone is in talks for numerous 100MW orders which would each triple revenues/EBITDA... and they have the capacity for **10 of them**.

Would love thoughts or feedback from anyone interested. I'm open for discussion.
Bloom Energy trades at 31x sales ($63B on $2B revenue) and its fuel cells degrade 5% annually, while its cooling solution still requires 2.82MW grid draw per 10MW compute, perpetuating the power shortage. The market has re-rated Bloom as a data-center power solution, but Capstone’s technology fully eliminates grid dependency for cooling, exposing Bloom’s relative weakness and extreme valuation premium. At 31x sales vs Capstone’s 2.8x, and with a fundamental cooling disadvantage, Bloom is overvalued and vulnerable to a correction as the market recognizes superior alternatives. Sentiment could remain frothy; Bloom may sign large deals or develop thermal recovery; short squeeze risk given high retail interest.
Capstone’s C1000S turbine recovers 50% of fuel input as thermal energy, covering 160% of a data center’s cooling load vs Bloom’s 57.7%, and uses zero grid draw for cooling. This technical advantage, combined with a clean balance sheet after Monarch Capital’s $112.5M redemption of Goldman’s preferred, enables fleet expansion and a return to a national exchange, unlocking institutional ownership. Capstone is mispriced as a hardware manufacturer (2.8x sales, 18x EV/EBITDA) while its services margins have surged to 88% and rental utilization is 98%, making it a compelling value play relative to bloated peers. OTC listing limits liquidity; execution on 100MW orders may disappoint; natural gas price volatility; competition from fuel cells or grid-scale solutions.
