by Jim Lane (Biofuels Digest) ... For two decades, the bioeconomy has struggled to squeeze new industrial possibilities through old regulatory openings. Too often, we’ve designed projects as though the feedstock, factory, customer, and carbon solution all had to occupy the same patch of ground—as though geography were an essential ingredient in chemistry.

Electricity escaped that trap long ago. The grid liberated generation from consumption. Renewable Energy Certificates (RECs) made it possible to account for renewable generation separately from the physical journey of individual electrons, even as the industry continues to debate the quality and consequences of different accounting methods.

Imagine the electric vehicle revolution if every Tesla needed its own dedicated, extension-cord-connected wind turbine. You’d need a rather large garage. And a very small Tesla. Yet that is effectively the logistical burden we’ve repeatedly imposed on biological carbon: bring everything together, then wonder why the economics don’t work.

The next great advance in industrial decarbonization may not require a new molecule, a new catalyst, or an exotic reactor. It may simply require a better set of keys.

The Cellulosic Crucible: When Geography Fought Chemistry

The bioeconomy should know better, because it has already lived through the consequences of trying to concentrate an entire agricultural supply chain around a single industrial facility.

Following the Energy Independence and Security Act of 2007, with its ambitious 16-billion-gallon cellulosic biofuel target for 2022, capital flowed into technologies designed to turn agricultural residues, wood, and other lignocellulosic materials into transportation fuels. The vision was compelling. America’s farms and forests could supply the raw materials for a new generation of biorefineries. Agricultural waste would become valuable fuel. Rural economies would prosper. But the factories needed enormous quantities of material that was bulky, inconsistent, seasonally available, difficult to transport, and surprisingly reluctant to cooperate with industrial machinery.

Corn stover, wheat straw, and bagasse are wonderful things in a field. They are rather less wonderful when they bridge inside a hopper, jam a conveyor, wear out equipment, or resist the chemistry intended to break them apart.

Pioneer facilities developed by Abengoa, DuPont, POET-DSM, Beta Renewables, Clariant, and others demonstrated both impressive technical achievements and the unforgiving realities of commercial scale-up. Only Iogen and Versalis made it through, only Iogen had multiple licenses operating at scale.

...

A large facility required a sufficiently concentrated supply of agricultural material within an economically tolerable collection radius. Scale the factory too far, and the feedstock bill could overwhelm the efficiencies of scale.

...

But what if we could do some of the biological work close to the source, convert heterogeneous waste into a standardized energy carrier, and then move that energy through infrastructure already built?

The Great Escape: When Biology Found the Gas Grid

Renewable Natural Gas offered one answer. Anaerobic digestion and landfill gas recovery made it possible to capture methane from biological waste streams. After upgrading, the resulting biomethane could meet pipeline specifications and enter existing natural gas networks.

...

Better still, environmental attribute systems made it possible to contract for eligible renewable gas production and assign its verified environmental characteristics to another gas user, subject to the applicable market’s rules. The physical gas could follow the network. The contractual environmental claim could follow a documented chain of custody.

This was the bioeconomy’s equivalent of discovering the electrical grid.

...

What if we stopped moving hydrogen across the country, and started making it exactly where it’s needed?

The Hydrogen Catch-22: The Customer Is Here, the Clean Energy Is Somewhere Else

Industrial hydrogen has a geography problem.

Petroleum refineries need it for hydrotreating and other operations. Ammonia producers need it for fertilizer. Chemical manufacturers need it as an essential feedstock. These established applications account for the overwhelming majority of dedicated hydrogen demand. They aren’t speculative markets waiting for a hydrogen economy to materialize. The problem is supplying them with cleaner hydrogen at an acceptable delivered cost.

Electrolytic hydrogen can be attractive where abundant low-carbon electricity is available at competitive prices. But new production facilities can face expensive power supply requirements, transmission constraints, grid interconnection delays, and capital-intensive equipment.

Conventional natural gas reforming with carbon capture offers another route, but carbon capture carries costs, and upstream methane emissions can materially weaken the lifecycle result.

And hydrogen itself is a notoriously inconvenient traveler. Its low volumetric energy density means transporting substantial quantities of gaseous hydrogen requires compression, specialized equipment, and potentially dedicated pipelines. Liquefaction introduces additional equipment and substantial energy requirements.

The hydrogen may be clean when it leaves the factory. That doesn’t mean it will be cheap when it arrives at the customer’s gate. Meanwhile, CO₂ capture projects can face the opposite problem: a useful industrial facility may be far from suitable geological storage, requiring expensive new CO₂ transportation infrastructure.

...

CH₄ + 2H₂O → CO₂ + 4H₂

...

Capturing carbon dioxide from these streams can be less energy-intensive than extracting dilute CO₂ from a power-plant smokestack. That doesn’t mean the carbon capture is free. SMR also creates furnace emissions, and high overall capture rates require additional equipment, energy, and capital. ATR configurations can offer advantages when high capture rates are a priority.

But the process gives engineers an attractive starting point: industrial hydrogen production and concentrated carbon separation can be designed together rather than treated as unrelated operations.

Now substitute eligible waste-derived RNG attributes for the conventional fossil natural gas supply, using an approved accounting system. The physical gas is withdrawn from the network at the industrial facility. Hydrogen is manufactured adjacent to its customer. Captured CO₂ is compressed, transported a short distance, and injected into a properly characterized, permitted geological formation.

...

First, produce renewable methane where biological resources are abundant.

...

Second, make hydrogen where demand already exists.

...

Third, store carbon where geology makes storage practical.

...

Let the gas move through existing infrastructure. Let the environmental attributes move through verified accounting. Let hydrogen and captured CO₂ travel the shortest practical distances.

...

The Key We Need: From Accounting Permission to Bankable Reality

Why isn’t this scaling overnight? Because recognizing an elegant solution in principle is not the same as making it work in practice. The Treasury Department’s January 2025 final Section 45V rules already acknowledged that renewable natural gas can support clean hydrogen production and established a framework for qualifying gas book-and-claim systems.

,,,

Legislation enacted in 2025 shortened the Section 45V construction-start deadline. Under current law, qualifying clean hydrogen facilities must begin construction before January 1, 2028.

...

A lender cannot finance an attractive theoretical carbon intensity score. It needs confidence that environmental attributes can be acquired, verified, retired, and recognized under the rules applicable to the project.

Nor does access to an attribute automatically create entitlement to every available incentive. Federal credits, state low-carbon fuel programs, and carbon sequestration incentives have different eligibility requirements and restrictions. Industrial hydrogen is not automatically eligible for transportation-fuel credits, and environmental benefits cannot simply be sold or claimed repeatedly.

The key must fit the lock.

The other critical constraint is geology.

...

Sometimes the most important innovation is the connection we no longer need to build.

For bioenergy, that means abandoning the assumption that everything valuable must happen in one place.

For regulators, it means recognizing that a trustworthy environmental accounting system can connect activities across geographical distances without pretending that physical molecules carry individual passports. For industry, it means designing projects around the locations where economic and environmental value can actually be created.

There will be hard questions. There should be hard questions. Methane leakage matters. Counterfactual emissions matter. Attribute ownership matters. Carbon storage integrity matters. But hard questions are reasons to build rigorous measurement systems, not reasons to insist that every farm, factory, and customer share the same zip code.

The electrical industry has spent more than a century creating the network that allows power to be produced in one place and consumed somewhere else. The bioeconomy has a remarkable opportunity to use an existing gas network to accomplish something similar. READ MORE
