The Digest’s 2025 Multi-Slide Guide to Hydrogen Combustion for Locomotive Engines via CFD

The Digest’s 2025 Multi-Slide Guide to Hydrogen Combustion for Locomotive Engines via CFD

September 4, 2025 |

This project develops and validates advanced CFD tools for hydrogen combustion in large-bore locomotive engines, aiming for up to 100% H2 operation. Simulations evaluated hydrogen substitution rates, diesel injection parameters, and compression ratios on combustion performance. Key findings showed a shift from mixing-controlled to flame propagation combustion with increasing H2, identifying conditions leading to high […]

The Case of the Vanishing Boiler: A Holmes & Watson Inquiry into Rock Energy Storage

The Case of the Vanishing Boiler: A Holmes & Watson Inquiry into Rock Energy Storage

September 4, 2025 |

I. A Season Turns It was the kind of morning when New York seemed suspended between seasons. The heavy languor of summer had broken overnight, swept out by a thunderstorm that left the air cool and restless. Fog hugged the East River, and the slick pavements gleamed with the last of the rain. For me, […]

The Digest’s 2025 Multi-Slide Guide to Off-Road Decarbonized Fuel Transient Performance

The Digest’s 2025 Multi-Slide Guide to Off-Road Decarbonized Fuel Transient Performance

September 3, 2025 |

This project evaluates the transient performance of Hydrogen Internal Combustion Engines (H2-ICEs) for off-road vehicle decarbonization. Utilizing an Engine-in-Loop (EIL) facility, the team demonstrated closed-loop tractor duty cycles with a Navistar diesel engine, developing and validating agricultural tractor models. Infrastructure for H2 fueling is complete. Key findings include presented fuel consumption and NOx emissions for […]

The Digest’s 2025 Multi-Slide Guide to Slashing PGM in Catalytic Converters

The Digest’s 2025 Multi-Slide Guide to Slashing PGM in Catalytic Converters

September 2, 2025 |

This “atoms-to-autos” project aims to reduce Platinum Group Metal (PGM) use in catalytic converters by 50%. It focuses on developing catalysts with single-atoms or small ensembles of palladium and rhodium, alongside engineered support materials for enhanced aging resistance. The project achieved 60% PGM thrifting at the core sample level with equivalent performance and identified optimal […]

Fuels, Strategic: Why Biomethanol Matters More Than Ever

Fuels, Strategic: Why Biomethanol Matters More Than Ever

September 2, 2025 |

Biomethanol is quietly emerging as one of the most compelling levers in the decarbonization of both renewable chemicals and marine propulsion—a bit like cryogenic CO₂ in food processing: pragmatic, powerful, and often underappreciated. Drawing on my experience in commodity-based technologies, I see biomethanol providing the same kind of transformational shift in shipping and chemical feedstocks. […]

The Digest’s 2025 Multi-Slide Guide to Low Lifecycle Carbon Fuel Combustion Models

The Digest’s 2025 Multi-Slide Guide to Low Lifecycle Carbon Fuel Combustion Models

September 1, 2025 |

This project develops predictive combustion and emission models for low lifecycle carbon fuels (LLCFs) across hard-to-decarbonize sectors. Key advancements include improved kinetic models for sustainable aviation fuel (SAF) components like cyclohexane and methylcyclohexane, and a novel Jet-A surrogate. The team also enhanced the Zero-RK software for faster chemical kinetics solutions and released GPS-Z for efficient […]

Following the science: Why bioenergy needs a seat at the SBTi table

Following the science: Why bioenergy needs a seat at the SBTi table

September 1, 2025 |

By Michael Goldsworthy, VP, Climate Impact at Elimini Special to The Digest For many years now, the Science Based Targets initiative (SBTi) has led the way in setting the standard for corporate climate commitments. At the heart of SBTi is a simple ethos: follow the science. This ethos has played a large part in the […]

The Digest’s 2025 Multi-Slide Guide to Green Gas Production Targets and Challenges

The Digest’s 2025 Multi-Slide Guide to Green Gas Production Targets and Challenges

August 28, 2025 |

EU directives target 35 bcm renewable gas by 2030, with the Netherlands aiming for 1.1 bcm Green Gas, 0.55 bcm via gasification. This necessitates building approximately 14 (30 MWth) plants in NL and 175 across Europe by 2030. Implementation faces challenges like higher costs, insufficient long-term subsidies, and diverging policies favoring manure digestion. Future integration […]

Hydrogen’s Horizon: Going for the Green in Ryder Cup style

Hydrogen’s Horizon: Going for the Green in Ryder Cup style

August 28, 2025 |

Ryder Cup. Bethpage Black. The 17th hole. Two hundred and thirty-two yards into a stiff crosswind. The pin is tucked back-left, the nastiest spot on one of golf’s nastiest holes. The green is wide up front, but narrows to a sliver toward that back corner. Miss it left or long and you vanish into a […]
