CMU analysis finds BEVs powered with natural gas-based electricity have about 40% of the lifecycle GHGs of a conventional gasoline vehicle
August 21, 2015
According to a new lifecycle analysis by a team at Carnegie Mellon University, a battery electric vehicle (BEV) powered with natural gas-based electricity achieves around an average 40% lifecycle greenhouse gas (GHG) emissions reduction when compared to a conventional gasoline vehicle. Plug-in hybrids (PHEVs), either with a 30- or 60-km range, when powered by natural gas electricity, have the second lowest average emissions. Both BEVs and PHEVs provide large (more than 20%) emissions reductions compared to conventional gasoline, but none of them is a dominant strategy when compared to gasoline hybrid electric vehicles (HEVs), the team found.
Gaseous hydrogen fuel cell electric vehicles (FCEVs) and compressed natural gas (CNG) vehicles have comparable life cycle emissions with conventional gasoline, offering limited reductions with 100-year global warming potential (GWP) yet leading to increases with 20-year GWP. Other liquid fuel pathways using natural gas—methanol, ethanol, and Fischer–Tropsch liquids—have larger GHG emissions than conventional gasoline even when carbon capture and storage technologies are available. The study is published in the ACS journal Energy & Fuels.
Fulcrum Bioenergy awards $200M EPC contract to Abengoa for MSW-to-jet plant
May 07, 2015
Fulcrum BioEnergy has awarded a $200-million fixed-price engineering, procurement and construction (EPC) contract to Abengoa for the construction of Fulcrum’s first municipal solid waste (MSW) to transportation fuels facility, the Sierra BioFuels Plant. The Sierra BioFuels Plant will utilize Fulcrum’s process for converting MSW into renewable syncrude that will then be upgraded to jet fuel. (Earlier post.)
The Fulcrum process begins with the gasification of the organic material in the MSW feedstock to a synthesis gas (syngas) which consists primarily of carbon monoxide, hydrogen and carbon dioxide. This syngas is purified and processed through the Fischer-Tropsch (FT) process to produce a syncrude product which is then upgraded to jet fuel or diesel.
EPA finalizes GHG permit for $1B gas-to-gasoline plant in Texas; 8M barrels per year
October 03, 2014
The US Environmental Protection Agency (EPA) has issued a final greenhouse gas (GHG) Prevention of Significant Deterioration (PSD) construction permit to Natgasoline LLC to construct a new motor-grade gasoline production facility in Texas that uses natural gas as feedstock (gas-to-gasoline, or GtG).
Natgasoline is a new wholly owned greenfield methanol production complex being developed by OCI N.V. The proposed new GtG facility will comprise two main process operations: a methanol plant with a capacity of almost 1.75 million metric tons of methanol per year, and the methanol-to-gasoline plant (MTG), which will produce more than 8 million barrels of gasoline per year. The methanol plant will use natural gas delivered by pipeline as feedstock; the MTG plant will primarily use methanol from the methanol unit, but can also process methanol from other manufacturers.
Groundbreaking in Turkmenistan for major synthetic gasoline plant; first full-scale Haldor Topsøe TIGAS facility
September 27, 2014
In August, a groundbreaking ceremony was held in Ovadan-Depe near the capital of Ashgabad in Turkmenistan to launch the construction of a major plant focused on the conversion of natural gas into synthetic gasoline. The plant will be based on Haldor Topsøe’s TIGAS (Topsøe Improved Gasoline Synthesis) technology (earlier post) and will become the first full-scale large commercial facility using this technology.
The plant has been awarded by the national gas company Turkmengas, and Topsøe will be working alongside the Japanese contractor Kawasaki Heavy Industry Ltd. and the Turkish contractor Rönesans Turkmen to engineer and construct the facility. The plant will be become operational in approximately four years from now with a daily production capacity of 15,500 bbl of synthetic gasoline.
Maverick Synfuels introduces affordable small-scale methane gas-to-liquid modular methanol plants
September 26, 2014
Maverick Synfuels (earlier post) introduced a small-scale, modular methane-to-methanol production plant that can be co-located at the methane source. The Maverick Oasis system allows producers to monetize biogas and natural gas (including associated or flare gas, and stranded gas reserves), as an alternative to producing electricity or venting greenhouse gases into the atmosphere.
The Maverick Oasis factory-built Gas-to-Liquids (GTL) methanol plants are modular, and can be rapidly deployed onsite to produce thousands of gallons per day of methanol from natural gas or methane-rich waste gas. The plants are designed to be low-cost, highly efficient facilities optimized to generate an attractive project rate of return. Each Oasis modular facility comes equipped with performance guarantees based on the designed methanol output rating.
USDA closes on $105M loan guarantee to Fulcrum for biorefinery converting municipal waste to renewable jet fuel; first USDA loan for biojet
September 04, 2014
The US Department of Agriculture (USDA) has closed on a $105-million Biorefinery Assistance Program loan guarantee through Bank of America, N.A. to Fulcrum Sierra Biofuels, LLC to build a biorefinery to produce jet fuel from municipal solid waste (MSW) via a proprietary two-stage thermochemical process. (Earlier post.)
USDA Rural Development’s loan guarantee represents less than half of the $266 million project cost. The plant is expected to produce 11 million gallons of fuel annually. This is the first loan guarantee USDA has made for the production of bio jet fuel.
