The race to slash carbon emissions by 2050 is well underway 鈥� on a course laid out through ambitious commitments at many levels, from the global Paris Agreement, through Massachusetts鈥� Global Warming Solutions Act, to the university鈥檚 Climate Action Plan.

But there鈥檚 a hurdle to reducing greenhouse gas emissions by replacing fossil fuels with renewable energy sources: energy storage. Today鈥檚 electrical grids require on-demand energy from coal, oil, natural gas, hydro and nuclear to avoid power disruptions and blackouts; they aren鈥檛 designed to run solely on intermittent renewable energy sources such as wind and solar.

To help clear this hurdle, faculty and student researchers from UMass Lowell recently completed a report on 鈥�The State of Grid Energy Storage in Massachusetts (pdf)鈥� for the Associated Industries of Massachusetts (AIM). The report examines the current state of utility-scale energy storage in the commonwealth (such as existing technology, key barriers and state and federal incentives) and offers recommendations for future policies and incentives.

The report鈥檚 authors 鈥� faculty researchers Christopher Niezrecki, Ertan Agar, Hunter Mack and Aaron Smith-Walter, graduate student Zachary Traverso 鈥�19 and undergraduate student Maria Fonseca-Guzman 鈥� presented an executive summary of their findings to more than 100 leaders from business, education, government and research at a conference, 鈥淭he Role of Energy Storage in Our Carbon-Free Future,鈥� held recently at the UMass Lowell Inn & Conference Center.

鈥淓nergy storage is a game-changer with the potential to revolutionize how society operates,鈥� says Niezrecki, a professor of mechanical engineering and director of the university鈥檚 Center for Wind Energy. 鈥淭he question is, what are we going to be doing in the next decade? And that鈥檚 a tough question to answer, because nobody really knows what the energy landscape is going to be.鈥�

The report recommends that lawmakers encourage investment in building, owning and operating new systems through policy incentives and long-term contracts. It also calls for further study of future energy storage needs.

鈥淭he technology that will be successful will win primarily because of economics,鈥� Niezrecki said. 鈥淲hat can be most cost-effective, not only on initial capital expenditures, but also on supply chain?鈥�

Without utility-scale energy storage, the report predicts that the commonwealth鈥檚 commitment to reduce carbon emissions by 80 percent by 2050 鈥渨ill likely fall short.鈥�

鈥淚 believe the people in this room are up to that challenge,鈥� state Rep. Tom Golden 鈥�94 told conference attendees, adding that he鈥檚 鈥渆mboldened鈥� by the research work led by Niezrecki and Vice Chancellor for Research and Innovation Julie Chen to find energy storage solutions.

鈥淯Mass Lowell is doing a fabulous job from the engineering side. I truly believe they are solving tomorrow鈥檚 problems today,鈥� said Golden, a Manning School of Business alum. 鈥淭oday鈥檚 students, who are studying at a cutting-edge university, are going to find that next piece in energy that鈥檚 going to make us the greenest state in the nation.鈥�

The students took a leading role in the report, researching current literature, identifying gaps in understanding and outlining recommendations.

Traverso, a master鈥檚 student in energy engineering from Townsend, has researched flow batteries (electrochemical cells that provide chemical energy) for the past four years with Agar, an assistant professor of mechanical engineering.

鈥淓nergy storage is a passion of mine,鈥� says Traverso, who earned his bachelor鈥檚 degree in mechanical engineering last spring. Over the summer, he participated in a National Science Foundation program called I-Corps, interviewing more than 100 people from the energy industry around the world about their energy storage needs.

鈥淭o be able to do something like this, as a student, is really amazing,鈥� Traverso says. 鈥淚鈥檝e been able to get so much experience learning about different technologies, policies and outlooks. It鈥檚 really been eye-opening.鈥�

Fonseca-Guzman, a junior chemical engineering major from Georgia, had already been researching energy storage on her own when she was invited to be part of the AIM report by Mack, an assistant professor of mechanical engineering.

鈥淎s soon as I got to UMass Lowell, I realized there are so many opportunities in these areas,鈥� says Fonseca-Guzman, who as a sophomore did an Honors fellowship on the political and technical challenges related to developing solar and storage initiatives in Massachusetts. Last spring, she presented her work at the New England Energy Research Forum at Worcester Polytechnic Institute, winning a second-place poster prize.

鈥淭his (AIM) report has really enlightened me as a scientist and engineer to the decisions I鈥檓 going to make in proposing new technologies, because the policy and the market matter so much,鈥� she says. 鈥淲e always need to keep that in mind.鈥�

Agar, who led the study, said the students really did 鈥渕ost of the work.鈥�

鈥淲e were just facilitating the project,鈥� says Agar, who joined the students, along with Niezrecki and Mack, for an academic panel discussion on the findings. 鈥淭hey did a fantastic job.鈥�

The event also included a panel discussion with AIM Senior Vice President Robert Rio, Department of Energy Resources Commissioner Judith Judson, Greentown Labs CEO Emily Reichert and Golden.

Reichert noted that one of the report鈥檚 recommendations is to educate people about the benefits and impact of grid-scale energy storage.

鈥淭hese are important challenges for the state, for entrepreneurs and for students to be focusing on,鈥� Reichert said. 鈥淚 think events like this, and reports like this, are incredibly important.鈥�
