Rolls-Royce successfully tests 12-cylinder mtu engine with pure hydrogen

Green Car Congress

Rolls-Royce has conducted successful tests of a 12-cylinder gas variant of the mtu Series 4000 L64 engine running on 100% hydrogen fuel. For several months, the mtu gas engine has been undergoing bench testing and continuous improvement in terms of efficiency, performance, emissions and combustion using 100% hydrogen as fuel.

CPKC orders 3.6MW of Ballard fuel cells for expansion of hydrogen locomotive program

Green Car Congress

Over the past two years, Ballard has supplied CPKC with 20 fuel cell engines for use in three different types of locomotives, with combined fuel cell power of 4MW. As an initial step in the collaboration, CSX plans to convert one of its diesel locomotives using a hydrogen conversion kit developed by CPKC.

Carbon Recycling International and Johnson Matthey collaborate on sustainable methanol

Green Car Congress

Carbon Recycling International (CRI) and Johnson Matthey (JM) have agreed on a long-term exclusive catalyst supply agreement for the use of JM’s KATALCO methanol catalysts in CRI’s Emissions-To-Liquids (ETL) CO 2 -to-methanol plants. Conventional methanol production involves fossil feedstocks such as natural gas or coal.

DOE releases draft guidance for Clean Hydrogen Production Standard (CHPS)

Green Car Congress

However, hydrogen hubs funded in support of the BIL ( earlier post ) will be required to “demonstrably aid achievement” of the CHPS by mitigating emissions across the supply chain to the greatest extent possible (e.g., by employing high rates of carbon capture, using low-carbon electricity, or mitigating upstream methane emissions).

Northwestern/Princeton study explores air quality impacts of aggressive conversion to EVs

Green Car Congress

Researchers from Northwestern University and Princeton University have explored the impact on US air quality from an aggressive conversion of internal combustion vehicles to battery-powered electric vehicles (EVs). coal, oil, natural gas, and biomass). at high EV adoption fractions. for April-September, (e, f) PM 2.5

Optimized heavy-duty CI engine fueled with DME delivers diesel performance, significantly reduces engine-out emissions

Green Car Congress

With the most recent design, an increase of the efficiency level of around 1–2 percent-points can be expected. The engine was also equipped with an electrically driven volumetric pump in the exhaust gas recirculation (EGR) path which gives the freedom to set any desired EGR rate, independently from the pressure ratios across the turbocharger.

Air France KLM signs 210M gallon SAF offtake agreement with DG Fuels

Green Car Congress

The feed-stock reduction is achieved primarily by supplementing the process with oxygen and hydrogen produced by water electrolysis units that are powered by clean wind and solar generated electricity. DGF replaces the coal gasification used by others with biomass gasification and natural gas reforming.
