Why Plug Power and Westport Fuel Systems Gained but Bloom Energy Dropped Today

As of 11:45 a.m. EST, shares of Plug Power (NASDAQ: PLUG) and Westport Fuel Systems (NASDAQ: WPRT) had gained 3% and 12%, respectively. Plug Power and Bloom Energy shares have been on a tear lately, after company-specific news and the beginning of what many believe will be a more supportive federal government for clean energy growth. Westport Fuel Systems is generally known as a natural gas fuel technology company, but today it announced an agreement with Swedish truck and bus maker Scania for a hydrogen engine research project.
