Hyliion is not that speculative given how low its market cap remains. x.com 

Hyliion's Q2 makes KARNO more likely to become a real commercial platform, even as full commercialization slips to 2027. Revenue was $4.9M versus about $2.4M expected, FY26 guidance rose to about $15M, and the 2026 cash burn outlook fell to $30-35M from about $50M, meaningfully reducing dilution risk. A $41.7M Navy contract, multi-MW validation and hyperscaler talks on tens to hundreds of MW add support. Execution risk remains until binding datacenter orders arrive. x.com  x.com 

Hyliion's data-center story is weakening because its key VFG Holdings partnership seems to have vanished. VFG, signatory of a nonbinding LOI for up to 50 MW of KARNO units, went unnamed on the Q2 call, and the June 30 10-Q never mentions VFG or the LOIs. The first multi-megawatt data-center delivery is now slated for 2028, and commercialization of the 200 kW KARNO Power Module slipped from end-2026 to 2027. The $41.7 million US Navy contract is the one bright spot. x.com 

QuantumScape has a second growth leg the market is not pricing: battery-in-rack backup for AI data centers. Its non-combustible ceramic separator lets cells sit inside server racks, buffering millisecond power spikes faster than external UPS systems as racks pass 100 kW. In EVs, Honda signed a development deal after validating hardware. A hyperscaler design win would re-rate it as AI infrastructure. It has $904M of liquidity, but is pre-revenue and depends on scaling its Cobra process reliably. … Show more

HVDC and 800V DC power delivery is the theme to focus on now, with STMicroelectronics, Navitas, Hyliion and Ideal Power as the preferred bets. Across the AI buildout, power and optics keep gaining narrative strength and attention, while packaging remains critical but is increasingly well understood by the market. x.com  x.com 

Hyliion has pivoted many times, and its latest move is just another attempt to save the business, so investors should be careful. x.com 

Demand for off-grid power and abundant natural gas make small power-generation plays like FuelCell Energy and Hyliion worth a small long-term position. Each could rise 3-5x quickly if it lands a couple of deals, though each also carries real risk of failure. Bloom Energy is great, but another 5x from here will be tough. x.com 

FuelCell Energy could ride AI data-center power demand with high-temperature fuel cells for clean baseload, scaling 12.5MW FuelCell Blocks for hyperscalers. At about a $650 million market cap, it has $170 million of TTM revenue, Q1 up 61%, a $1.17 billion backlog, $312 million of cash and output ramping to 350MW. Risks are negative gross margins, cash burn, dilution and unproven execution; @SueWallSt notes its 1.5GW of data center deals are proposals and backlog shrank. High risk, high reward. … Show more

Hyliion's KARNO generator has value, but not for data centers. Data centers do not want the maintenance or the logistics of relying on trucks to bring fuel, even if, as a reply argues, the unit can be moved on a flatbed and run on many fuel types. x.com 

FuelCell Energy looks asymmetric now that its funding and equity raise are behind it, leaving a huge cash balance alongside good data-center traction. x.com
