GE Vernova has announced its next generation of mobile aeroderivative gas turbines, for power delivery on or off the grid. The new TM2500 DLE (dry low emissions) unit is GE Vernova’s waterless, mobile 34 MW power plant that offers up to 39 % efficiency, with reduced NOx emissions and waste.
The mobile power solutions trend is being driven by a variety of factors. The global energy access gap is worsening as population growth outpaces new connections – 760 million people are living without electricity access. The vast majority of that growth will happen in areas where the power grid is either very weak or does not exist at all. Another major driver is the need for emergency power for utilities, municipalities, data–centres and other industries. Therefore in an increasing number of countries, utilities are investing in rapid, highly mobile technology that can quickly bridge the power gap during blackouts, energy shortages or even natural disasters.
The TM2500 DLE exhibits the same reliability as earlier models, but is the first to operate without water and without any after–treatment in emissions, as it produces lower nitric oxide (NOx), carbon monoxide (CO), and particulate matter (PM) emissions compared to previous mobile solutions, and almost no methane slip.
The modular TM2500 DLE is said to be more compact and easier to ship. It is on a two-trailer frame that offers on-site flexibility and a 30-day lead time from contract to commissioning. It has a five-minute fast start cycle, well suited to rapid response duties in reacting to changes in power demand or grid stability. The unit’s mobility and speedy start up cycle allow the unit to meet a variety of needs in multiple locations, and it is fuel flexible, running on gas, liquid fuel, or hydrogen blend, and so can sidestep possible fuel supply challenges or fluctuating costs.
