Biochar Production (Pyrolysis)
& Profit from Carbon Credits

Biochar Production via Pyrolysis or Gasification

Biochar can be created from a range of agricultural feedstocks such as wood, nuts, shells, litters, manures, straw and stalks all can contribute to this process. The result is a usable, marketable product that is growing in demand across the world.

Biochar production through either pyrolysis or gasification are two of the simplest, most measurable and cost-effective methods of carbon capture and storage (CCS) available today. Biochar production generates a massive amount of heat, between 350 to 900° C, which is often lost to the environment if not reused within the process. Capturing and using that heat adds value to your operation when reused or converted to usable electricity. Operating costs can be normalized and predictable. The cost of energy used in operations can be reduced,flattened and predictable over time since the energy is only related to the amount of heat and not dependent upon grid utility prices. Lastly, generating onsite carbon-free electricity may increase the quality and quantity of Carbon Removal Credits ( CDR ) / carbon credits.

Profit from Biochar

Generating Electricity from the Biochar Process

The heat which is lost to the air can be captured and harnessed to create electricity. That electricity can go right back into your operation to reduce operating costs, or put to use in other ways. By capturing this otherwise vented heat, biochar producers can get more value from their existing biochar process and feedstock. ElectraTherm’s units provide a very simple option to capture and harness biochar heat, and then convert that energy to 75-250 kW of power per unit. Once the electricity is generated, it can be used easily in any application across your enterprise.

Our Moduł zasilania75 produces fuel-free, emission-free power from various low-grade waste heat sources using the Organic Rankine Cycle (ORC) and the company’s patented BITZER semi-hermetic twin screw expander/generator combination. Our Power+ Generator, our heat to power solution, is designed to generate clean electricity from sources of low temperature heat. The Power+ Generator also doubles as a combined heat and power (CHP) unit, generating up to 85°C of usable thermal in addition to electricity.

This application of creating electricity from the biochar waste heat is efficient and capitalizes on the basic principle of reducing waste. It is best suited for stationary applications where the biochar processing takes place in a fixed-location facility.

Generating Carbon Credits from the Biochar Process

Organic feedstock sources such as wood, nuts, shells, litters, manures, straw and stalks are high in carbon — in the range of 60-80%. Because they are renewable resources and relatively fast growing, they are good solutions for carbon capture – an increasing business opportunity for both farmers and biochar producers.

Biochar as a product is an industrial-scale, commercial solution that allows carbon sequestration. Because the raw materials (e.g. straw, grasses, nut shells, manures, etc) are well understood and in high-volume production, the value of biochar carbon credits tends to be fairly attractive. This economic cycle is robust enough that it is not difficult to find brokers that specialize in selling carbon credits from biochar.

One benefit of carbon removal via biochar is that it is permanent. Once the carbon is captured by the plant and processed into biochar, it is extremely stable and durable. It has myriad uses in both developed and developing economies.

The criteria for receiving carbon credits from biochar generally include:

Using sustainable biomass
Biochar pyrolysis equipment
Market to sell the biochar
Registration with a carbon credit governing body, or a certified professional that can manage the process for you

The Market for Biochar Carbon Credits

According to a report from investment advisors MSCI, “Demand for biochar carbon credits has doubled each of the last two years, with prices trading consistently over USD 100/metric tonnes (mt) of carbon dioxide equivalent. The latest modeling by MSCI Carbon Markets suggests demand for this project type could grow 20-fold over the next 10 years.”

Biochar is treated in the marketplace as a carbon removal technology, often called carbon capture and storage, or CCS. As the markets for CCS continue to grow due to government mandates, the economics of the market for biochar carbon credits naturally will grow along with it. The use for biochar itself as a product has sufficient benefit to stand on its own. When you add in the fact that carbon credits are available for biochar producers, the business model becomes even more attractive.

Per MSCI, the price for biochar carbon credits has been in the range of $100-200 USD. As with other markets, the price will vary. One helpful aspect of biochar is that it can be produced from a wide range of feedstocks. As a producer, accessing lower cost feedstock is another variable at your disposal to meet your financial and production goals.

The Market for Biochar as a Product

According to Fortune Business Insights, the global biochar market was $763 million in 2024, and is projected to grow to $2.1 billion by 2032. Renewable energy mandates target biochar as a scalable market for carbon capture and downstream revenue. Biochar can be used on its own or as ingredients in landscaping products.

Biochar as a product has a wide range of applications already built into the developed and developing economy.

Soil health: agriculture, garden, landscaping, turf, trees, horticulture, composting
Environmental: environmental remediation, erosion control, wetlands, odor reduction
Water: storm water filtration, water treatment, functionalized chars, 3D aerogels
Forestry: wildfire fuel reduction, reforestation, growing media, revegetation
Carbon: carbon sequestration, carbon credits, renewable energy offsets

Nieodłącznym elementem każdego systemu pirolizy biowęgla jest praca w wysokiej temperaturze (często przekraczającej 700 stopni Celsjusza), co czyni go idealnym do wytwarzania energii z odzysku ciepła odpadowego. Dotyczy to zarówno biomasy rolniczej, takiej jak łuski ryżowe, włókna trzciny cukrowej (zwane również wytłokami z trzciny cukrowej) lub łuski orzechów drzewnych, jak i innej biomasy, takiej jak drewno, wycinka drzew, tarcica lub odpady drzewne, a także biosolidów związanych z dużymi partiami zwierząt, takimi jak ściółka drobiowa lub laguny z odpadami trzody chlewnej i wołowiny.

Adding waste heat recovery power generation
to a pyrolysis application provides multiple benefits

WARTOŚĆ KREDYTU WĘGLOWEGO

Prawie wszyscy operatorzy biowęgla starają się dziś wykorzystać możliwości finansowe związane z usuwaniem dwutlenku węgla, znane również jako kredyty CDR dostępne na dobrowolnym rynku emisji dwutlenku węgla (VCM). Połączenie produkcji energii z odzyskiwaniem ciepła odpadowego stanowi okazję do zwiększenia wartości powstałego biowęgla poprzez zmniejszenie intensywności emisji dwutlenku węgla.

ZGODNOŚĆ Z PRZEPISAMI

Wytwarzanie energii z ciepła odpadowego pomaga zmniejszyć podatki od emisji dwutlenku węgla i jest dobrze przygotowane do pomocy w nadchodzących wymogach zgodności, takich jak unijne ramy usuwania dwutlenku węgla (ECRF).

ZAAWANSOWANE TECHNOLOGICZNIE WYKORZYSTANIE CIEPŁA

Wiele z najbardziej szanowanych organizacji zajmujących się certyfikacją kredytów węglowych zaleca lub wymaga wykorzystania ciepła odpadowego w celu zakwalifikowania się jako "zaawansowana technologicznie" operacja cieplna. Ciepło odpadowe do wytwarzania energii elektrycznej przy użyciu ORC spełnia tę potrzebę, jednocześnie zaspokajając zapotrzebowanie operacji na energię elektryczną przy jednoczesnym zmniejszeniu śladu emisyjnego.

ZMNIEJSZA KOSZTY OPERACYJNE

Zmniejszając (lub prawie eliminując) zapotrzebowanie na źródła energii oparte na węglu (takie jak energia elektryczna z sieci miejskiej) podczas pirolizy i zastępując je bezemisyjnym wytwarzaniem energii, zmniejszają się ogólne koszty operacyjne systemu.

ZWIĘKSZONA WARTOŚĆ BIOWĘGLA

Biowęgiel, który jest wytwarzany w sposób najbardziej przyjazny dla środowiska, będzie bardziej atrakcyjny na otwartym rynku, ponieważ "odbiorcy" o wysokiej wartości będą dążyć do pozyskiwania biowęgla od certyfikowanych dostawców najbardziej przyjaznych dla środowiska. W związku z tym biowęgiel z systemów pirolizy obejmujących wytwarzanie energii z ciepła odpadowego będzie cieszył się większym popytem.
