Novel membrane-free Mg-CO2 battery sequesters CO2 and generates electricity

Green Car Congress

Researchers at the Ulsan National Institute of Science and Technology (UNIST) have designed a membrane-free (MF) Mg-CO 2 battery as an advanced approach to sequester CO 2 emissions by generating electricity and value-added chemicals without any harmful by-products. A paper on the work is published in the journal Nano Energy. —Kim et al.

GTI quantifies opportunity to produce low-carbon renewable natural gas (RNG) from wood wastes

Green Car Congress

GTI has released a site-specific engineering design titled “ Low-Carbon Renewable Natural Gas (RNG) from Wood Wastes ”. GTI led a team of engineers and scientists to produce a blueprint for converting an existing biomass facility into an RNG production site, using the wood waste feedstock and some of the existing infrastructure.

Nauticol Energy & Enhance Energy plan to capture up to 1M tonnes of CO2 annually from blue methanol production and distribution

Green Car Congress

The technology is designed to deliver ease of operation, reduced downtime and maximum energy efficiency. Our plant design was already targeted to be a global leader in low emissions. Enhance earlier announced 1 million tonnes sequestered via the Alberta Carbon Trunk Line (ACTL)—a 240 km network transporting CO 2 in Alberta.

Wärtsilä to supply a major LNG/bioLNG production plant for CO2-neutral transport fuels

Green Car Congress

Wärtsilä’s experience and state-of-the-art technologies developed for the process design, fabrication, and delivery of gas liquefaction plants and mature gas treatment solutions prior to liquefaction, were key factors to secure the contract. The feedstock for bioLNG is based on biological waste material—e.g. Copyright: Wärtsilä.

Cambridge researchers develop standalone device that makes formic acid from sunlight, CO2 and water

Green Car Congress

It’s been difficult to achieve artificial photosynthesis with a high degree of selectivity, so that you’re converting as much of the sunlight as possible into the fuel you want, rather than be left with a lot of waste. —first author Dr Qian Wang from Cambridge’s Department of Chemistry. —senior author Professor Erwin Reisner.

New Mærsk Triple-E ships worlds largest and most efficient; waste heat recovery and ultra long stroke engines contribute to up to 50% reduction in CO2/container moved

Green Car Congress

Besides its size, which provides superior economies of scale compared to other vessels (more cargo means less CO 2 per container moved), the efficiency of Triple-E comes from its innovative design. An advanced waste heat recovery system captures and reuses energy from the engines’ exhaust gas for extra propulsion with less fuel consumption.
