Advanced Biofuels Development

Renewable Natural Gas Modelling using Apen Plus West Biofuels has developed an integrated pilot-scale process that converts forest biomass into pipeline-grade renewable natural gas (RG) and high-value liquid chemicals. By combining a proven gasifier with a robust catalytic reactor and a simplified hydrate-based separation system, the project can adjust process conditions to yield both methane-rich gas and marketable alcohols like ethanol and propanol. 🟦 Process Design: Aspen Plus simulation was used to conduct the process modelling. 1️⃣ Gasification: The gasification process utilizes an indirect heating loop where forest residue is thermally converted into syngas, tars, and char within a low-pressure entrained flow gasifier. The system relies on circulating synthetic olivine sand, pre-heated to over 1,800°F (982°C) in a separate char combustor, to provide the necessary thermal energy, while injected steam stabilizes the flow. After gasification, cyclones separate the resulting syngas from the solids; the char is then burned in a fluidized bed to reheat the olivine, which is recycled back into the gasifier to sustain the continuous loop. This efficient cycle not only generates syngas but also captures hot flue gas to facilitate feedstock drying and general heat recovery. 2️⃣ Gas clean up and methanation To prepare the gas for final processing, the mixture undergoes a water-gas shift stage to reach a specific 3:1 hydrogen-to-carbon monoxide ratio, followed by acid gas removal using a Selexol system. The final purification relies on a three-stage adiabatic methanation process operating at approximately 30 bar, which ensures the fuel meets strict pipeline standards by converting remaining syngas into methane. By modelling these reactors at equilibrium, the system efficiently maximizes conversion while maintaining the necessary thermal control through intermediate cooling between stages. 3️⃣ Integrated steam system and power generation cycle The plant maximizes efficiency by integrating a conventional steam cycle with the biomass conversion process, utilizing a network of pre-heaters and steam generetors to produce steam for gasifier injection, distillation, and acid gas removal. Electricity is primarily generated through two steam turbines with intermediate reheat, supplemented by turbo-expanders that recover energy from pressurized unreacted gases. To ensure the design is economically and thermally optimized, a pinch analysis was conducted to design a heat exchanger network that captures energy from high-temperature streams and recycles process condensate.

Researchers in Japan have been developing innovative technologies that can convert water and carbon dioxide into liquid fuels, a breakthrough that could potentially transform how energy is produced in the future. This approach focuses on synthesizing hydrocarbons using renewable energy, essentially creating fuel from basic chemical ingredients already present in the environment. The process typically begins by splitting water into hydrogen and oxygen through electrolysis, a technique powered by electricity. When renewable electricity from solar or wind power is used, the hydrogen produced becomes a clean energy carrier. Scientists then combine this hydrogen with carbon dioxide captured from the atmosphere or industrial emissions. Through advanced catalytic reactions, the hydrogen and carbon dioxide can be converted into synthetic hydrocarbons, which behave similarly to conventional fuels such as gasoline, diesel, or jet fuel. These synthetic fuels are sometimes referred to as e-fuels or carbon-neutral fuels because the carbon released during combustion can theoretically be balanced by the carbon captured earlier. Japan has been investing heavily in this field as part of its long-term energy strategy. With limited natural fossil fuel resources, the country has focused on developing technologies that can produce energy domestically while reducing carbon emissions. Although the technology is still evolving and currently expensive to scale, synthetic fuel production could become an important component of future energy systems. By transforming carbon dioxide from a pollutant into a resource, these innovations may help reduce emissions while providing sustainable alternatives to traditional fossil fuels.

Can we replace coal with a carbon-negative biofuel? Building on conversations from #COP28, I explore an innovation that has the potential to revolutionize how we think about #sustainable #energy in my newest Forbes article: carbon-negative #biofuel. This technology not only offers a promising alternative to coal but also actively removes carbon dioxide from the atmosphere— a critical step in the fight against #climatechange. Transitioning to a cleaner energy future calls for bold ideas, scalable solutions, and cross-sector collaboration. One such bold idea has been developed by the start-up NextFuel AB, which generates briquettes of fuel using a variety of feedstocks, from sugarcane leaves to elephant grass. Ultimately, NextFuel envisions a world in which much of the agricultural waste in the local region is recycled and used for generating biofuel through torrefaction - quite exciting I find.

📚 My Weekend Reading Clean Energy Technology Observatory: Renewable Fuels of Non-Biological Origin in the European Union - 2025 Status Report on Technology Development, Trends, Value Chains and Markets ➡️ Source: https://lnkd.in/dbSqThYb ✅ Some Key Takeaways: 📌 Technology status ▪️ RFNBO production technologies involve electrolysers and the downstream conversion of renewable hydrogen into synthetic fuels, mostly based on established industrial processes using fossil-based inputs, now adapted for renewable hydrogen and captured carbon CO2 or N2 as feedstocks. ▪️ Technology Readiness Levels (TRLs) vary from 5–7 for innovative variants, up to 8–9 for commercially ready pathways like e-methanol and e-CH₄. ▪️ Most RFNBO technologies are at pilot or early commercial scale, with no fundamental technical barriers, but with substantial economic and infrastructure challenges to overcome. ▪️ Installed capacity remains modest, with approximately 35 operational e-methane plants in 2024 and total EU e-fuel capacity below 0.5 Mt/year, although project pipelines (45 announced e-kerosene (SAF) projects and several Power-to-X (PtX) hubs) are expected to expand capacity to a few hundred thousand tons per year by 2030. ▪️ Cost trends indicate strong learning effects: CAPEX for synthesis plants is projected to decrease by 30–35% by 2050. By 2030, several studies estimated production costs at €1.6–2.3 per litre of diesel equivalent for e-methanol and over €3.5 per litre for Fischer–Tropsch fuels, but the current trend could push these costs higher. 📌 Investment and funding ▪️ Public funding for research and innovation under Horizon 2020 and Horizon Europe has reached €200 million for over 40 projects, focused on RFNBO production. ▪️ Other EU initiatives can also indirectly finance RFNBO projects by leveraging complementary funding streams, EU public support for innovation readiness, and private capital for commercialisation and scale-up. ▪️ Commercial-scale projects still rely heavily on public guarantees and offtake agreements. 📌 Value chain ▪️ The RFNBO value chain integrates renewable hydrogen production, CO2/N2 capture, chemical synthesis, and fuel distribution, spanning multiple industrial sectors. ▪️ Early deployment is concentrated in Germany, Denmark, the Netherlands, and Spain. ▪️ The economic potential is considerable: RFNBO could contribute over €40–60 billion annually to the EU economy by 2040, creating up to 200,000 direct and indirect jobs in the hydrogen, chemical, and transport sectors. 📌 EU positioning and global competitiveness ▪️ The EU maintains global leadership in RFNBO research, demonstration, and regulatory frameworks, but lags behind the US and China in commercial scale-up. ▪️ Under the Net-Zero Industry Act, the EU aims to secure 40% domestic production of strategic net-zero emission technologies by 2030.

Friends, 🇱🇻♻️ Latvia has approved a new support scheme for biomethane. Is Ukraine🇺🇦 ready to take the next step? The Latvian government has launched a comprehensive mechanism to stimulate biomethane production: • grants and loans for constructing biomethane plants and infrastructure • CAPEX compensation of up to 50-65 % • support for refueling stations and biomethane transport • project completion deadline - 2029 This is not just Latvia’s energy strategy. It is a signal to all EU countries seeking to reduce fossil fuel imports and boost domestic production of renewable gases. 🔍 Why does this matter for Ukraine? Ukraine holds one of the largest biomethane potentials in Europe. Agricultural residues, manure, silage, beet pulp, organic fractions of municipal waste - all of this can be converted into high-value energy, exported to the EU, replace natural gas and generate new revenue for communities and businesses. We can become not only a country with potential, but the biomethane hub of Eastern Europe. ⚡️ What steps can Ukraine’s Ministry of Energy take to introduce a similar support model? 1. Introduce a dedicated State Biomethane Support Program • CAPEX grants (20-40 %) • interest rate compensation • long-term preferential loans for equipment (8-12 years) 2. Create a national Biomethane Development Fund Possible structure: state capital + donors + EBRD/EIB. Priority - projects with IRR > 12-15 %, local feedstock, export capacity to the EU. 3. Implement a Green Gas mechanism • guarantees of origin • electronic registry • ability to sell to EU traders • integration with European gas exchanges 4. Provide tax incentives • accelerated depreciation • exemption from import duties and VAT on critical equipment • reduced corporate tax rate for the first 5 years 5. Support infrastructure development • grants for biomethane refueling stations • support for biomethane-powered transport (municipal fleets + agrologistics) 6. Simplify permits and procedures • a one-stop window for biomethane projects • clear deadlines for approvals • digitalization of grid connection procedures 7. Integrate the agricultural sector • incentives for cooperation between agroholdings and biogas plants • targeted programs for farmers with small feedstock volumes 🚀 Our opportunity 2025-2030 Biomethane is not only about ecology. It brings: • new local jobs • energy security • high-margin EU export potential • modernization of the agricultural sector • reduced dependence on imported gas It is time to act. Ukraine can adopt Latvia’s model - and make it even stronger. Whoever starts first will take the market.

✈️ Yesterday, the long-awaited Methanol-to-Jet SAF report—featuring policy, techno-economic, and commercial outlook—was released by the Methanol Institute. Key takeaways from the report for me: • Methanol-to-jet technology is approaching the commercialization stage, with several leading technology developers—including Honeywell UOP, Topsoe, and ExxonMobil—advancing their MTJ processes. • The MTJ pathway is in the final approval stages under the ASTM D7566 standard, which would enable its commercial use in aviation. This includes Synthetic Paraffinic Kerosene (MTJ-SPK) and Cycloparaffinic Kerosene with Aromatics (MTJ-CKA). • MTJ can deliver 70–90% lifecycle emissions reductions when using biomethanol or e-methanol. • MTJ is cost-competitive versus other advanced SAF pathways, such as ethanol-to-jet (alcohol-to-jet) and Fischer–Tropsch. • The MTJ SAF project pipeline is rapidly growing, with about 2 Mt of MTJ SAF capacity under development. I’m delighted that GENA Solutions Oy was among the contributors to this report. We continue to see strong growth in MTJ development: the project pipeline increased from 1.8 Mt as of August 2025 (the data used in the report) to 2.2 Mt as of today. Even more importantly, three MTJ projects commenced FEED over the past several months, supporting the report’s conclusions. All these projects will require nearly 6 Mt of renewable methanol, creating substantial potential for e-methanol and biomethanol development. 🔗 Full report: https://lnkd.in/dTjfbbqv #SAF #Aviation #Decarbonization #MTJ #Methanol #Biofuel #Efuel
