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, […]
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 […]
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 […]
By Steve Weiss, co-founder and CEO of Grey Heron, and long-time member of the Due Diligence Wolfpack Special to The Digest Getting your prospects to sign meaningful LOIs is your gateway to lots of benefits: getting other partners to move forward with you, getting investors to sign up – and simplifying final agreements with the […]
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. […]
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 […]
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 […]
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 […]
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 […]
Integrating bioenergy is essential for flexible renewable energy systems, addressing increasing demands for short- and long-term flexibility, electrification support, and carbon management. Flexible bioenergy helps resolve intraday and seasonal electricity mismatches by producing storable fuels like methane or LNG. It also valorizes hydrogen, supports defossilization by creating fuels and chemicals, and enables negative emissions via […]
