Conventional reciprocating engines and gas turbines have problems combusting landfill gas that is below 30-40 percent methane. So, when a landfill becomes inactive, the quality of the emitted landfill gas drops. And as the landfill gas’s methane content goes below 30 percent, the traditional decision is to decommission the power generation equipment, at which time the landfill will stop generating revenues from the sale of energy.
A changing power-generation landscape has led to new challenges for both wind-turbine manufacturers and makers of turbine components. Will a shift toward new technology ensue?
Intersolar 2015 attracted a wide array of innovators eager to show their new solar products to the industry. Cost reduction, increased performance, and faster installation times were three of their goals.
Low-enthalpy capture could ultimately be transformative for the geothermal-energy industry.
The historic carbon-cutting plan could be just enough to spur states to build more wind and solar capacity — but they have to act fast.
In today's fast-paced tech environment, no one can make a splash quite like Elon Musk. So when he decided to enter the energy storage game in 2014, he did it with gusto. Musk is now in the process of building what he coined a "gigafactory," which is a lithium-ion battery manufacturing plant in Nevada. Of course, the plant is being built at such an efficient pace that its ahead of schedule and is now set to start production in 2016. Since the gigafactory plans were revealed, Musk has continued to wow the industry with announcements like the unveiling of Powerwall, a residential storage system that pairs with rooftop solar, which can be financed and installed by his other company that you may have already heard of, SolarCity.
The announcements are fairly frequent: SunPower Partners with Admirals Bank for $200 Million Solar Loan Program, Deutsche Bank to Lend $1 Billion for Japanese Solar Projects, Financing Partnerships Drive North Carolina's Solar Boom. The reasons for the deals are clear. Solar developers need money to build projects and rather than going to the bank again and again with deal after deal, it makes sense to have a financing partner and a set of criteria you need to meet already in place so that you can be sure the money will materialize when you need it.
Renowned for its vast hydropower resources, the Himalayan nation of Nepal has nonetheless long struggled to meet its growing power demand. Now though, the devastating earthquake that struck the country in April 2015 is placing even more emphasis on the development of hydropower at a range of scales.
Marine mammal monitoring and underwater noise mitigation is an integral part of the development of offshore wind farms, which, along with many other developments, generate underwater noise that can negatively impact marine mammals. For instance, servicing vessels used during construction and operation can generate continuous noise at low frequencies, which overlap with the communication signals of many marine mammals, such as baleen whales. In fact, each operation in the development of offshore wind farms has its own acoustic signature that must be identified and quantified in order to assess its impacts on species present in the area.
