The Triogen e-box converts waste heat from diesel engine exhausts into electricity and is a zero-carbon technology. Like solar photovoltaic (PV) power, it can reduce fuel consumption in off-grid diesel power plants. The e-box can save significant quantities of fuel, with a one third quicker payback times than solar, and with much simpler engineering integration requirements. This paper presents a case study of a mine with a constant 10MW electrical load supplied by 10 diesel genset units each providing 1MW of power, with a fuel consumption of 0.26 l/kWh and fuel costs of $1.0/l. Three hybrid power plant options and their economics are:
Triogen will be back at this year’s “Investing in African Mining Indaba 2018” from February 5th to 8th in Cape Town, South Africa. After a successful introduction of the e-box at last year’s Indaba, the company reached a new milestone within the industry by winning the Mining Cleantech Challenge 2017 in Denver, Colorado.
The Mining Cleantech Challenge is a competitive showcase hosted by Colorado Cleantech Industries Association (CCIA) in partnership with minors such as Fresnillo, Newmont and Jolimont Global. During this competition companies get the opportunity to present innovative technologies that connect mining industry operators, OEMs, and clean technology solution providers in finding ways that impact the bottom line as well as the ‘social license to operate’ to operate.
Reducing energy cost and emissions is a key topic for the mining industry. In general diesel generators convert only 40% of the fuel energy into electricity. All the remaining energy is wasted by being exhausted into the air. Triogen’s Organic Rankine Cycle (ORC) technology converts this unused heat into electricity by generating 170kW electric power when the hot exhaust gas passes through the ORC. By feeding this power into the grid on site, a single ORC saves the equivalent of 300,000 litres of fuel per year with a payback of approx. 2 years. This cost efficient solution also makes mine sites more environmentally friendly and energy efficient, and addresses the UN Sustainable Development goals.
Triogen’s CEO Henning von Barsewisch looks back on a very dynamic year:
“2017 has been a progressive year for us: winning the Colorado Mining Cleantech Challenge, securing a reference site as well as getting additional financial backing and trust from within the industry. This third party acknowledgement confirms our conviction in our technology as being an innovative solution for energy efficient mining.”
Triogen’s “e-box” is based on the experience of more than 1 million operating hours. Engineered to fit into two 20ft. shipping containers, the ‘plug in, save fuel’ solution is made to withstand the harshest conditions and is designed specifically for remote-site generators.
Triogen has emerged as the winner of the Mining Cleantech Challenge hosted by the Colorado Cleantech Industries Association (CCIA) in Denver Colorado. The company received a $5,000 cheque and recognition by mining executives and investors for its innovative product, the e-box ORC. Triogen, the only European company competing, was voted the best among a field of 8 strong competitors from the U.S. and Canada.
The inaugural Mining Cleantech Challenge aims to connect mining industry operators, OEMs, and clean technology solution providers in finding solutions that impact the bottom line as well as its license to operate.
Triogen now offers a new approach to cutting fossil fuel use in mining. With its heat recovery technology, the company will provide the extractive market with a newly packaged energy efficiency technology for high-speed diesel generators at the Investing in African Mining Indaba 2017 from February 6th to 9th.
According to a report by the University of Cambridge, the mining industry represents about 2.7% of worldwide industrial energy use. This energy demand is largely served by diesel-powered machinery.
Energy efficiency is the most important strategy in this industry. However, diesel generators convert only 40% of the fuel energy into electricity. The remaining energy is essentially wasted as heat into the atmosphere.
Triogen’s Organic Rankine Cycle (ORC) technology converts the unused exhaust heat into electricity. When the hot exhaust gas passes through the ORC, it generates 170kW electric power, which the engine does not need to provide. Over the course of a year, this leads to five fuel trucks that can be taken off the road per ORC. The savings correspond to a 5-8% fuel reduction per engine. This solution is cost effective, environmentally friendly and reduces risks for the mines by reducing fuel movements and increasing the reach of on-site fuel storage.
Triogen’s “e-box” is based on the experience of more than 700.000 operating hours. Engineered to fit into two 20ft shipping containers, it is made to withstand the harshest conditions and is designed specifically for remote-site generators.
The Energy Saving and Cost Reducing e-box is a high temperature, high efficiency medium scale ORC, which converts waste heat from generators into electricity. Easy to install, easy to operate, safe and remotely monitored while reducing operational risk and generally guarantees a short-term ROI. It is the ideal solution for the (remote) Mining Industry.
Remote off-grid mines run their generators mainly on diesel fuel and the e-box offers the first serious step in using more environmentally friendly and energy efficient options. The e-box not only cuts back on the overall use of diesel (5-8%) and therefore the often massive energy bill, but it also increases the strategic fuel reserves locally kept at the Mining sites. This consequently leads to fewer fuel trucks on the road. Moreover, this relatively modest investment brings about a significant decrease in existing operational risks while simultaneously contributing to reaching a number of the United Nation’s Sustainable Development Goals set to be achieved by 2030.
Triogen is a leading ORC (Organic Rankine Cycle) supplier that has successfully incorporated world-class technology into a reliable standardized innovative product. With its mission to passionately develop and deploy innovative waste-heat recovery technology addressing the energy and environmental challenges of our planet while serving its customers, the company is a valued contributor to help sustain energy efficiency in the mining industry.
All around us, there is unused energy available from production processes and Triogen’s e-box creates an energy source that does not replace renewable solutions, but focuses on using existing resources more efficiently without creating additional carbon gasses.
In a time when the extractive industry has reached another level of reviewing/using green/renewable energy using residual heat from generator exhaust emissions and converting it into electricity is the alternative that offers a less intermittent solution and a very attractive ROI.
