Mitsubishi gas turbine being developed to burn ammonia commercially by 2025

Mitsubishi Power is developing a 40-MW gas turbine that would be fueled 100 percent by ammonia. The Japan-based power equipment giant, which already is hard at work adapting its natural gas-fired turbines to burn hydrogen, now is aiming at another potential carbon-free power resource. The company hopes to guide the ammonia-fired technology toward commercialization by 2025. […]

4.5 GW of pumped-storage hydro could save UK up to £690 million annually

A new study by independent researchers from Imperial College London has found that just 4.5 GW of new long duration pumped hydro storage, with 90 GWh of storage, could save up to £690 million per year in energy system costs by 2050, as the UK transitions to a net-zero carbon emission system. Commissioned by SSE […]

Pumped storage hydro, utility-scale batteries return about 80% of the electricity they store

Pumped-storage hydroelectric facilities in the U.S. operated with an average monthly round-trip efficiency of 79%, and the utility-scale battery fleet operated at 82%, according to 2019 data from the U.S. Energy Information Administration (EIA). Round-trip efficiency is the percentage of electricity put into storage that is later retrieved. The higher the round-trip efficiency, the less energy is […]

Siemens Energy to build novel waste heat-to-power facility in Canada

Siemens Energy has signed an agreement with Canada-based TC Energy Corporation (TC Energy) to commission what is said to be a first-of-its-kind waste heat-to-power pilot installation in Alberta. The facility will capture waste heat from a gas-fired turbine operating at a pipeline compression station and convert it into emissions-free power. The electricity produced will be […]

Renewables now account for 24% of US’ total energy generation capacity

Renewable energy sources (i.e., biomass, geothermal, hydropower, solar, wind) strongly dominated new US energy generation capacity additions in 2020, according to the SUN DAY Campaign of data released by the Federal Energy Regulatory Commission (FERC). Combined, renewables accounted for 22,451MW, or more than three-quarters (78.09%) of the 28,751MW of new utility-scale capacity reported to have […]

Ohio geologists study potential for geothermal in abandoned coal mines

The research at Ohio University could help transform old fossil fuel sites into clean energy assets, though much work remains to be done. Geologists at Ohio University are exploring the potential to turn abandoned coal mines into sources of carbon-free heating and cooling. Ohio is home to thousands of abandoned coal mines, which have become […]

University of Tennessee, Knoxville, professors contribute to DOE hydropower research

Two professors at the University of Tennessee, Knoxville, are contributing research to the Submarine Hydrokinetic and Riverine Kilo-megawatt Systems (SHARKS) program of the U.S. Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) project. This project aims to speed up the process of making hydrokinetic turbine designs for tidal and riverine currents economically viable. Hydroelectric power accounts for […]
