For ADGE, approximately 98.76% of the ADGE shares present at ADGE's Special Meeting of Stockholders voted in favor of the adoption of the Merger Agreement. The shares present represented approximately 70.92% of ADGE's total outstanding shares of common stock as of April 24, 2017, the record date. The Merger became effective today, May 18, 2017, approximately 4:00 P.M. EST. ADGE shareholders will receive notices from Continental Stock Transfer, Tecogen's exchange agent, regarding the process of exchanging their ADGE stock for shares of Tecogen common stock. Tecogen® Inc. designs, manufactures, markets, and maintains high efficiency, ultra-clean cogeneration products including natural gas engine-driven combined heat and power, air conditioning systems, and water heaters for residential, commercial, recreational and industrial use. Tecogen is known for cost efficient, environmentally friendly and reliable products for distributed power generation that, through patented technology, nearly eliminate criteria pollutants and significantly reduce a customer's carbon footprint. Tecogen's natural gas powered cogeneration systems (also known as combined heat and power or "CHP") are efficient because they drive electric generators or compressors, which reduce the amount of electricity purchased from the utility while recovering the engine's waste heat for water heating, space heating, and/or air conditioning at the customer's building. Tecogen manufactures three types of CHP products: Cogeneration units that supply electricity and hot water including the InVerde® 100, InVerde e+®, CM-75 and CM-60; Chillers that provide air-conditioning and hot water marketed under the TECOCHILL® brand name; and Ilios® branded high-efficiency water heaters. Tecogen's CHP products are sold directly to customers by our in-house marketing team, and by established sales agents and representatives, including ADGE. ADGE installs, owns, operates and maintains complete distributed generation, or DG systems or energy systems, and other complementary systems at customer sites and sell electricity, hot water, heat and cooling energy under long-term contracts at prices guaranteed to the customer to be below conventional utility rates. As of December 31, 2016, ADGE had 92 installed energy systems, representing an aggregate of approximately 5,445 kilowatts, or kW, 41.6 million British thermal units, or MMBtu's, of heat and hot water and 4,500 tons of cooling. kW is a measure of electricity generated, MMBtu is a measure of heat generated and a ton is a measure of cooling generated.

Patent
Tecogen | Date: 2015-10-13

A system and method for controlling an internal combustion engine and electrical inverter system for powering a load, including controlling the operation of a spark-ignited internal combustion engine prime mover used in generation of electrical power by way of a generator. A microprocessor (e.g., DSP) controlled circuit taking engine speed input from an engine speed signal is used to control the operation of the internal combustion engine prime mover so that it is preferably operated substantially at wide open throttle.

A system for reducing ammonia in exhaust gas generated from a lean burn internal combustion engine includes an oxidation catalyst, a selective reduction catalyst (SCR), a cooling unit, and a three-way catalyst. Exhaust gas generated by the engine passes through the oxidation catalyst to oxidize carbon monoxide from the exhaust gas to form carbon dioxide. Nitrous oxide (NOx) compounds in the exhaust gas are reduced in the SCR to form nitrogen and water. The exhaust gas is then cooled in a cooling unit and then passed over the three-way catalyst. The three-way catalyst causes ammonia in the cooled exhaust stream to react to form less harmful compounds, such as nitrogen and water.


Methods and apparatus for removing undesired pollutants from exhausts streams of spark-ignited internal-combustion engines in vehicles while producing electrical energy as a byproduct. The apparatus includes a reduction catalyst, a thermoelectric generator (TEG), and an oxidation catalyst. The TEG cools the exhaust stream and generates electricity. The exhaust stream is oxygenated after passing through the TEG and prior to passing through the oxidation catalyst.


Patent
Tecogen | Date: 2016-03-24

A poison-resistant catalytic converter includes a washcoat having a support material comprised of titania and/or silica and a plurality of platinum group metal particles disposed in the support material. The washcoat is disposed on a substrate having a plurality of cells that define respective apertures. The catalytic converter is resistant to poisoning from sulfur and phosphorous compounds while operating at low temperatures. Applications include spark ignited internal combustion engines in combined heat and power systems, vehicles, combustion turbines, boilers and other applications for utilities, industry and vehicle emissions control.


An assembly and method for reducing nitrogen oxides, carbon monoxide and hydrocarbons in exhausts of internal combustion engines, wherein the exhaust is acted upon in a first stage catalytic converter. A first portion of the first stage catalytic converter output is cooled and a second portion of the catalytic converter output is not cooled. The cooled and not cooled exhausts are united and directed to a second stage catalytic converter. Air is injected into a selected one of (1) the not cooled exhaust prior to the juncture thereof with the cooled exhaust, and (2) the combined cooled and not cooled exhausts after the juncture thereof.

A method of operating a catalytic system for reducing emissions from a rich burn spark-ignited engine, comprising controlling intake air and fuel (AFR) to produce first exhaust gases substantially free of oxygen; passing said first exhaust gases into a first-stage catalyst chamber containing a three-way catalyst (TWC) operating above 800 F, which minimizes NOx content by reducing NOx (to N_(2) and O_(2)). Further, passing exhaust gases exiting from the first-stage catalyst chamber to an inter-stage cooling chamber having cooling means, and cooling by-pass means, which are used to adjust gas temperature to a controlled Tmix = 390 - 520 F, as well as secondary air injection means, which enriches the oxygen content to about 0.25 - 1.0%; passing exhaust gases exiting from the inter-stage cooling chamber to a second-stage catalyst chamber containing a catalyst that minimizes CO content by oxidizing CO to CO_(2).
