Coolbrook Oy (Helsinki, Finland; www.coolbrook.com) has successfully completed the first phase of large-scale pilot testing (photo) for its RotoDynamic Technology at the Brightlands Chemelot Campus in Geleen, the Netherlands. During 2023, Coolbrook has been running a test program to demonstrate…
Precise degradation control is key to advanced bioresorbable polymers
Bioresorbable polymers — those that degrade naturally over time and can be absorbed by the body — are essential for delivering a number of advanced biomedical technologies to patients, including long-acting injectable or implanted products, regenerative scaffolds, degradable medical devices,…
Closed-loop CO2-based energy-storage system slated for Wisconsin
Alliant Energy (Madison, Wis.; www.alliantenergy.com) was recently selected to receive a $30-million grant from the U.S. Dept. of Energy’s Office of Clean Energy Demonstrations (OCED; Washington, D.C.; www.energy.gov/oced) for a proposed 200-MWh energy storage system. Alliant Energy’s new battery system,…
Using waste plastic to simultaneously make graphene and hydrogen
Building off of a process to efficiently manufacture graphene (see Chem. Eng., April 2022, p. 9), a team of researchers from Rice University (Houston, www.rice.edu) have uncovered that the process can be easily altered to also produce a nearly pure…
Modular Construction Encourages New Applications
The efficiency and cost effectiveness of modularity provides advantages for small- and large-scale projects When the right conditions exist, the benefits of modular construction — from laboratory scale to large scale — are plentiful and allow single-source, cost-effective and efficient…
Hydrogen Production via Methane Pyrolysis: An Overview of ‘Turquoise’ Hydrogen
‘Turquoise’ hydrogen processes generate H2 without releasing CO2. Presented here are the opportunities and challenges for producing hydrogen by methane pyrolysis Hydrogen-producing processes are classified using a color scheme according to their carbon footprint (Table 1; [1–3]). So-called “turquoise hydrogen”…
Unipar modernizes chlor-alkali plant in Brazil with thyssenkrupp nucera technology
Unipar (São Paulo, Brazil) is modernizing its chlor-alkali plant at the Cubatão plant in Brazil by incorporating electrolyzers from thyssenkrupp nucera AG & Co. KGaA (Dortmund, Germany; ). To modernize the plant, the Brazilian chemical company, a leader in the…
Solar cells integrated into car hoods
In recent years, some car manufacturers have developed vehicles that integrate photovoltaic cells into the roof — the easiest surface to use for onboard solar-power generation. Now, researchers at the Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE; Freiburg, Germany;…
