Grzyb is president of North American PCM manufacturers association

Joe GrzybJoe Grzyb, CEO of Phase Change Energy Solutions of Asheboro, N.C., has been chosen to lead the new Phase Change Materials Industry Association of North America.

Members of the association, gathered for the association's inaugural meeting in Boston, Mass., on Thursday, approved bylaws, outlined goals and created committees to develop strategies to pursue those goals. The eight founding members attending the meeting were Phase Change Energy Solutions; Microtek Labs, Dayton, Ohio; Encapsys LLC, Appleton, Wis.; Outlast LLC, Golden, Colo.; Croda Inc., Edison, N.J.; Insolcorp Inc., Las Vegas, Nev.; Cold Chain Technologies, Franklin, Mass.; and Entropy Solutions, Plymouth, Minn. 

The meeting, hosted by the Fraunhofer Center for Sustainable Energy Systems, was led by the association's newly elected executive director, Jan Kosny, who heads Fraunhofer's Building Enclosures & Materials group. Also attending were representatives of the Massachusetts Clean Energy Center and the U.S. Department of Energy's Building Technologies Office; as well as David Yarbrough of R&D Services Inc., Cookeville, Tenn.

The association's mission is to promote the development and use of phase change material in North America. It has been established as a not-for-profit corporation in the state of Delaware. 

After much discussion, members approved the formation of committees to focus on four key areas and selected chairmen to lead them: PR/communications (Mark Hartmann, director of research and development at Outlast); government/policy (Tim Riazzi, CEO at Microtek); technical (Reyad Sawafta, chief scientific officer at Phase Change Energy Solutions); and codes/standards (Joe Grzyb).

Four membership types were approved:

General: Companies that manufacture PCMs; supply raw materials or processing equipment used in the PCM industry; or use PCMs in their products. General members have all the rights, privileges and responsibilities of membership, including the right to hold office and vote on matters put before the association. Annual dues: $2,000.

Associate: Businesses or individuals performing work related to phase change material. Associate members cannot vote or hold office. Annual dues: $1,000.

Academic/research: Organizations or individuals performing research related to phase change material. Such members cannot vote or hold office. Annual dues: $50.

Honorary: Persons who by virtue of their contributions to the industry and who are no longer employed by a general member are eligible for honorary membership. Such members will pay no dues.

The association tentatively plans to meet again in six months. Organizations or individuals interested in joining or working with the association should contact Jan Kosny at jkosny@cse.fraunhofer.org or Joe Grzyb at jgrzyb@phasechange.com

PATENTS

Controlled release microcapsules

U.S. patent application 20170281985 (applicant Encapsys LLC, Appleton, Wis.):

"A method of forming microcapsules having improved physical properties and release control as well as the microcapsules formed by the process wherein the capsule wall is formed by the concurrent polymerization of monomers, oligomer and/or prepolymers on the inside of the capsule wall and different monomers, oligomers and/or prepolymers on the exterior of the capsule wall as it forms. ... Microcapsules containing phase change materials according to the present invention are prepared using a process with a two-part water phase and a single core phase."

Immersion cooling systems and methods

U.S. patent application 20170290205 (applicant Hamilton Sundstrand Corp., Charlotte, N.C.)

"An electronics cooling arrangement includes a housing, an electronic device disposed within the housing, and a solid-liquid phase change material disposed within the housing and is in thermal communication with the electronic device to absorb heat generated by the electronic device. A method of cooling an electronic device and a vehicular electronics cooling system are also described."

IN BRIEF

• A bill that would create a tax credit for the purchase of energy storage systems, including thermal systems, is advancing in the U.S. Senate. The bill, known as the Energy Storage Tax Incentive and Deployment Act of 2017, is sponsored by Sen. Martin Heinrich (D-N.M.).  The bill was first floated last year and gained support from both Democrat and Republican senators, Energy Storage News reports.

Bloomberg BNA News reports that states could soon respond quicker to chemical accidents armed with information on file at the Environmental Protection Agency has. But first, they’ll have to prove they can protect chemical manufacturers' trade secrets.
