Program accomplishments

  • 1) CHeRN worked with Tami Bond, MinErgy and a Nepalese steering committee to improve gender and class inclusivity in Nepalese municipal energy planning. The work focused on developing personal agency to influence and contribute to an inclusive energy plan. Based on observation and outside evaluation, the efforts resulted in very promising results, most notable by a change in expression of agency among 5 out of 18 EDSC members. This was reflected in a) willingness to speak in an audience and b) an ability to describe the resources participants wished to have both for their communities and for themselves. This growth occurred in women and the in members of the Dalit community. 2)Support to Carbon Limits dealt with the reality that while satellite data is increasingly providing global methane leak and emissions data, regulators in many countries have not known what to do with this emerging data. Working with regulators in Bahrain and Kazakstan, the work focused on showing how satellite detections can lead to effective follow up, mitigation, and record keeping. The project made clear progress toward helping regulators better understand and manage satellite-detected emissions from the oil and gas sector. 3) Work progressed on the development and demonstration of the gaseous nuclear engine with Global Energy Research Associates. Evidence of progress has been the interest of Savannah River National Lab (SRNL) to use the engine for energy and to dispose of nuclear waste. Based on this interest the company's principal re-located to be close to SRNL.
