If you've looked into on-site renewable energy, solar was probably first on the list. It's familiar, affordable, and productive on a bright Louisiana afternoon. It's also booming: according to the U.S. Energy Information Administration, developers planned roughly 33 GW of new utility-scale solar in 2025, about half of all new U.S. generating capacity.
But the sun clocks out. Panels produce nothing at night and little on cloudy days, and batteries only store what the panels have already made. For a sawmill, food processor, or farm running around the clock, that gap matters. The fix? Pair solar with gasification.
Why gasification is the ideal partner
A downdraft gasifier like our bioHearth® system turns organic waste—such as wood chips, sawdust, crop residue, and cardboard—into clean-burning producer gas (syngas). Through high-temperature thermal conversion with minimal emissions, this syngas fuels internal combustion engines to deliver steady, dispatchable combined heat and power (CHP). While solar generation is inherently intermittent and limited by daylight and weather, the bioHearth® system provides continuous, carbon-neutral baseload power around the clock. This completes a microgrid setup, seamlessly filling energy gaps without relying on fossil fuels or grid power. That makes it solar's ideal teammate:
It runs on your schedule. With feedstock in the hopper, it delivers steady baseload power day or night, rain or shine.
The fuel is already on site. Waste you currently pay to haul away becomes fuel instead.
It's renewable too. You back up solar with biomass, not diesel or the grid.
How a solar + gasification hybrid works, around the clock
Daytime: Solar leads and the gasifier fills the gap. Spare solar power can run feedstock prep like chipping and drying.
Night and cloudy days: The gasifier carries the load, drawing on a feedstock stockpile instead of the forecast.
All day: Captured heat from the gasifier serves process needs or dries tomorrow's fuel.
A smart controller uses every free kilowatt-hour of sunshine first and leans on the gasifier only as needed.
What you gain by pairing them
Reliable power that doesn't depend on the weather: While solar generation fluctuates with sunlight availability, gasification provides continuous, controllable energy by converting organic feedstock into syngas on demand, eliminating unexpected power drops during storms, heavy cloud cover, or winter seasons.
Smaller battery systems required: Because a gasifier can directly generate electricity to handle overnight operations and extended overcast periods, facilities significantly lower capital expenditure by avoiding oversized, high-cost battery energy storage systems (BESS) and their associated degradation and replacement costs.
Lower waste disposal and tipping fees: A standard 200 kW bioHearth® system consumes around 400 lbs of biomass per hour. On-site waste streams like sawdust, crop leftovers, and packaging residue are converted directly into power, turning recurring tipping and hauling expenses into energy savings.
Maximum value per pound of feedstock: Utilizing combined heat and power (CHP) technology allows the system to achieve over 80% total efficiency by capturing thermal energy for space heating, crop drying, or process steam, while generating marketable biochar for soil enhancement or carbon sequestration.
Reduced utility grid vulnerability: Generating your own clean power shelters your operation from volatile energy prices, peak-demand surcharges, and grid instability as utility rates keep climbing.
Stackable financial incentives: Combining solar and gasification unlocks dual funding avenues, including federal Investment Tax Credits (ITC), Section 48 energy credits, USDA REAP grants, and accelerated depreciation (MACRS) (details).
Expanding Your Microgrid
The same logic works with wind, which has its own lulls, and with three-part microgrids: solar handles the day, a battery smooths quick swings, and the gasifier covers everything else.
The best fit is a site with steady energy demand, a reliable organic waste stream, and room for panels: sawmills and lumber yards, farms, food processors, rural communities, and municipal facilities like wastewater plants. Already have solar? A gasifier can turn daytime savings into 24/7 energy security.
Solar brings low-cost power when the sun is up. Gasification brings steady power from the waste you already have. Together, they deliver clean energy that's there when you need it.
The sun will always set. With the right partner, your power doesn't have to.
