A new engine converts waste hot water from industrial equipment into electricity.
NATURE WORLD NEWS - Exergyn, a startup based in Dublin, Ireland, is planning to run the first industrial trials of the new energy-efficient engine by next year, New Scientist reports. The engine generates electricity from heated water that is left over from other equipment. According to co-founder and chief executive Alan Healy, waste hot water (low-grade waste heat or LGWH) from industrial processes amounts to about twice the energy in Saudi Arabia's oil and gas output per year.

Combined heat and power (CHP) systems have long been used to reduce the overall energy intensity of industrial systems. There are two types of combined heat and power, depending on whether the system produces power first, then heat, or heat first, then power. Read more
Like the rest of CUC’s generators, the two new units will produce heat exhaust gases, however unlike the existing generators whereby these exhaust gases would be wasted and funneled out industrial grade smoke stacks into the atmosphere, CUC will now capture these gases which in turn will be converted into additional energy.

US waste-heat-to-power products maker Alphabet Energy said on Wednesday it has raised USD 23.5 million (EUR 21m) from a Series C financing round led by a new investor, oil and gas sector player Schlumberger (NYSE:SLB). Read more
A young startup is making flexible sheets of metal covered in tiny antennas that can turn heat into electricity.
Sound like the stuff of science fiction? The company, RedWave Energy, is working on the unusual idea that could, if successfully manufactured, help turn waste heat from power plants and factories into energy. Read more
Utah Associated Municipal Power Systems has announced the unveiling of a new clean-energy system that will simultaneously eliminate environmental waste and bring electricity to a number of cities in Utah, including Logan. Read more
Republic Cement also operates a Waste Heat Recovery system in its Teresa Plant in Rizal, which further improves energy efficiency by channeling excess heat from the plant’s production processes to generate electricity. The WHR supplies nearly 30% of the plant’s energy requirements, and reduces carbon dioxide emissions by approximately 12 000 tpy. Read more
'The whole idea of renewables versus non renewables has become a focus - the thing for me that Europe has got to do is be very strongly focused in delivering an energy system for all of our energy users in a way that is affordable.
'Fifty per cent of the energy lost in our system is heat from thermo-generation - we are throwing away as much heat as we are using. It's bad for the economy and climate.' Read more
This month a transparent tube topped by a turbine will be installed along the side of a Minneapolis grain silo in an effort to create electricity from wasted heat.
The 7.5-foot diameter tube – called the Energy Column – captures ground level air that rises to power a 3 kilowatt (kW) turbine. Read more
Commissioned in March, the Power+ runs off low temperature geothermal steam from a small district heating system. The power is sold to the local utility at an attractive feed-in-tariff rate for renewables. Read more

Recovering energy from waste heat is nothing new, but being able to do it cost-effectively on a small scale is. Starting with trains and trucks, such technology could be coming down the line.
PT Semen Indonesia Tbk has taken advantage of hot flue gases in the cement manufacturing process and turned them into energy.
Indonesia Cement Group is a pioneer in the use of hot exhaust gases into electrical energy through the project Waste Heat Recovery Power Generation (WHRPG). Read more

Transparency Market Research’s (TMR) new market study on the global thermoelectric devices market presents the development of this market across North America, Europe, Latin America, the Middle East and Africa, and Asia Pacific for the 2015-2023 period. The report, titled “Thermoelectric Devices Market - Global Industry Analysis, Size, Share, Growth Trends, and Forecast 2015 – 2023,” finds out how the utilization of thermoelectricity will help conserve energy and also fill the demand-supply gap in energy distribution to some extent.
