Through partnership with IDAEA-CSIC two AQMesh pods were co-located with a reference station and scaled locally in Barcelona (ref. Advanced user mode), providing R2 of 0.97 for NO and 0.89 for NO2. One pod was then moved to a second reference point within the city to establish repeatability of results using the scaling factors derived from the first reference. This resulted in a correlation of 0.98 for NO, and 0.86 for NO2. This trial shows that a high degree of air quality monitoring accuracy can be achieved through local scaling and this accuracy is maintained when AQMesh is then used to monitor independently in new locations.
Successful Testing of Full-Scale Preburner Keeps AR1 Engine on Schedule for 2019
Aerojet Rocketdyne, a subsidiary of Aerojet Rocketdyne Holdings, Inc. (NYSE:AJRD), recently conducted hot-fire tests to validate the design of the preburner for the AR1 rocket engine, which represents the nation`s lowest-risk, lowest-cost-to-the-taxpayer and fastest path to replacing the Russian-built RD-180 engine currently used to launch most U.S. national security payloads into space. "This important milestone keeps AR1 squarely on track for flight readiness in 2019," said Aerojet Rocketdyne CEO and President...
AQMesh can also be scaled using diffusion tubes
The AQMesh team has carried out a test which shows that calibration (scaling) of AQMesh against one, or ideally several, diffusion tubes, is a viable option when no local reference station is available. When three AQMesh pods and four NO2 diffusion tubes were co-located against a reference station, the diffusion tube readings were so consistent with the reference average reading for the period that the diffusion tube average could be used to apply a slope correction to AQMesh data. By careful management of the...
ADM Begins Operations for Second Carbon Capture and Storage Project
Archer Daniels Midland Company (ADM) recently announced that the Illinois Industrial Carbon Capture and Storage (ICCS) project, a partnership to safely and permanently store more than 1 million tons of carbon dioxide a year, has begun operations. "2017 is a watershed year for carbon capture in the United States. On the heels of the successful opening of Petra Nova in Texas, the Illinois Industrial facility serves as another example that large-scale CCS deployment works, is safe, and serves as a key component of...

New York PSC mandates grid-scale storage projects for investor-owned utilities
With the mass proliferation of energy storage capacity, New York regulators have mandated investor-owned utilities deploy energy storage systems by the 2018. The state Public Service Commission (PSC) issued an order last week requiring each individual utility to have energy storage projects “deployed and operating at no fewer than two separate distribution substations or feeders.” In addition, the projects should address at least two grid functions, such as boosting capacity or reducing peak load. &ld...
