Ethanol for Sustainable Aviation Fuels

Decarbonization pressures in the global aviation industry are driving demand for drop-in fuels with a lower carbon intensity than conventional jet fuel. Making a SAF product that is commercially viable at scale necessitates lower cost, highly efficient decarbonization solutions across the production pathways.

RHBs are the lowest cost route to SAF; enables SAF & upstream feedstock producers to reduce or fully eliminate scope 1 & 2 at new or existing facilities


RHBs are modular with versatile process integration capabilities to satisfy entire thermal and electric loads with a zero carbon electrification solution at scale, at the lowest cost.

Key Benefits

Baseload Thermal Power Icon

Baseload Thermal Power

Direct decarbonization of SAF production process; RHB captures renewable electricity and turns it into reliable baseload thermal (and electric energy with CHP) to satisfy 24/7 energy requirements. 

Decarbonization Icon

Decarbonizing Scope 1 & 2

GHG emissions dominated by feedstock production (ex: ~¾ total emissions in ethanol to jet pathway); RHB allows deep decarbonization of entire energy scope 1 & 2 energy inputs for feedstock production 

Seamless Integration Icon

Seamless Integration

Modular RHB technology ensures seamless integration across facilities of all sizes, from small-scale ethanol plants to large-scale SAF production, ensuring scalable SAF production at commercially viable volumes and costs.

Lowest CI SAF Icon

Lowest CI SAF

RHBs complement existing/ additional decarbonization efforts such as process efficiency upgrades, sustainable farming, and biogenic CO2 capture to attain the lowest CI SAF products.

Designed for your facility

Industry Challenges

Hydrocarbon fuels powering long-haul aircraft is a market that exceeds 100 billion gallons worldwide — about a third of it in the U.S. There is significant demand to replace petroleum-derived fuels with sustainable fuels

The U.S. has the capacity to produce 18 billion gallons of corn ethanol fuel. Corn ethanol delivers twice as many gallons per acre as soybean-derived fuels.

The Rondo Advantage

The Rondo Heat Battery can lower the carbon intensity of traditional biofuels like ethanol, biodiesel and renewable diesel by up to 50 percent.

Rondo Energy’s simple technology cuts ethanol CI scores by 50 percent or more now; unlocks large increases in value per gallon; and alongside carbon capture, offers a clear pathway for the ethanol industry to reach zero CI SAF – unlocking billions of dollars in profitability annually.
