IBM, AT&T and Sprint have stopped exporting used lead batteries to Mexican recyclers.
The US technology and communication firms have concerns that battery recyclers in Mexico fail to meet adequate health and environmental standards.
Mexico’s plans on secondary lead smelting regulations are too weak to cope with the high amount of used car batteries in Mexican factories, according to US lead-acid battery recycler RSR.
The proposal wants to set limits for lead emissions from the exhaust stacks of secondary smelters. According to RSR, almost one billion pounds of spent lead acid batteries are exported to Mexican recyclers each year.
Mexico’s Comisión Federal de Electricidad (CFE) has commissioned MAN B&W to install a 12K80MC-S9 two-stroke low-speed diesel engine for stationary applications at a power plant in La Paz, Baja California Sur, Mexico.
It is the fifth two-stroke engine that MAN B&W is to deliver to the Baja California Sur plant. The four already installed engines have a current output of 172.5MW. According to the supplier, the new engine is set to have an output of 47.88MW, 5MW higher than the 12K80MC-S predecessor, while possessing a lower rate.
The 12K80MC-S9 will run on local, cost-effective fuel with a viscosity of around 1,200cSt at 50°C and 4.3% sulphur content like the four predecessors in order to meet the local environment regulations, claimed MAN B&W.
The commission is part of a contract for the extension of CFE’s diesel power plant, that Spanish contractor Acciona is awarded for. Doosan Engine, MAN Diesel & Turbo’s Korean license holder, will construct the new engine.
An installation of a bottoming cycle steam turbine and a high-pressure selective catalytic reduction (SCR) for emission control is also planned under the contract.
Mexico’s energy reform allows private investments in power generation and commercialisation, while private investors in power transmission and distribution have to associate with state-owned CFE. The government aims to prevent monopolistic practices with this regulation and remain strategic status for transmission and distribution.
A Memorandum of Understanding has been signed for a power generation and energy storage project in Mexico City. The deal between AHIS, a developer and gaming company, and engine makers Scuderi Group sees Scuderi providing five gas-powered Split Cycle Engines for power generation and energy storage at five of its sites in southern Mexico.
The Scuderi Split-Cycle design allows the kinetic energy stored in the form of compressed air to be mixed directly with the energy stored in the fuel creating a more powerful and efficient way of producing electricity. The storage systems uses a unique combustion process that means the compressed air storage tanks require far less space than conventional compressed air energy storage systems. It combines high-pressure compressed air with the kinetic energy of the fuel to create a significant efficiency gain.
According to the agreement, Scuderi Group will build power generation and energy storage units to be installed at five AHIS casinos and, in line with local law, sell electricity back to the grid. Mexican law mandates that any private sources of power generation must sell equal amount to the regional grid. This is the first time Scuderi Group will be generating electricity for the Mexican grid.
