Low energy nuclear reactions (LENR, also referred to as “cold fusion”) is a controversial phenomenon that may be able to meet a substantial portion of the world’s energy requirements. LENRGY LLC was formed by Thomas W. Grimshaw, Ph.D., to provide consulting services and pursue policy changes to help realize the benefits of LENR. Achieving these benefits is promoted in several ways, such as policy analysis, supporting LENR researchers and undertaking outreach and communications.

This website is being developed to describe LENRGY, including its objectives, consulting services, and LENR experience. The website also provides information on the changing situation of LENR as a potential energy source. It is being developed as it is posted, so it is an ongoing work in progress.

What Is LENR?

LENR was announced in 1989 but was rejected by the mainstream scientific community within a year or so. However, research has continued in the field worldwide in the years since. A large and growing body of evidence indicates that LENR is a real phenomenon, and its benefits may yet be realized.

The potential benefits of LENR are immense. Not only would the energy source be cheap and virtually inexhaustible, it would also be environmentally secure, with little or no waste, no hazardous radiation, and no greenhouse gas emissions. LENR may also be flexible in deployment in either (or both) a centralized (e.g., power plants) or distributed (e.g., home heating) configuration. Click here for more information on LENR.


LENRGY’s mission is to help realize the benefits of LENR. This mission is accomplished by seeking changes in public policies toward LENR research, preparing to mitigate adverse secondary impacts, and assisting researchers in the field. LENRGY also seeks opportunities for outreach and communications, such as presentations on the status of LENR. Outreach and support for the field are provided as a public service and on a consulting basis where appropriate. LENR policy analysis work is mostly performed in connection with Dr. Grimshaw’s position as Research Affiliate at the Energy Institute of The University of Texas at Austin.

Policy Analysis

Public policies toward LENR generally followed the 1989 rejection and are mostly negative. However, continued research of LENR provides the basis for public policy updates. Policy changes are needed both for LENR support to realize its benefits and for preparing to address its potential adverse secondary impacts proactively. Dr. Grimshaw performs policy analyses for LENR support and realization utilizing evidence-based policymaking as a foundation. For secondary impact analysis and mitigation planning, technology assessment methodologies are utilized.

Research Support

LENRGY seeks to enhance the prospects of LENR by supporting researchers in the field. For example, proposals are prepared for research funding in collaboration with investigators. Researchers are also supported by documenting their previous and current research activities and organizing associated data files. In addition, consulting assistance is provided to entities that fund LENR research in evaluating proposed technologies and devices.

Communications and Outreach

Development of LENR and realization of its benefits can only happen if there is better understanding of the phenomenon and it’s changing status. Many developments in the years since the 1989 announcement and rejection have occurred that indicate these LENR benefits may yet be realized. LENRGY provides presentations, short courses, and similar outreach activities as a public service and on a consulting basis. These services seek to enhance understanding of LENR and it’s prospects in a variety of venues, such as corporations and academic settings.
