What is power-to-x? “Power-to-x” refers to a series of techniques and pathways allowing to convert, store and utilize renewable electrical energy. Power-to-x is specifically applicable when there is an excess of renewable electricity produced from solar or wind resources. Rather than be wasted—the specific industry term for this is “curtailed”—the excess electricity is used productively. The “x” can refer to a variety of energy carriers or uses. Power-to-hydrogen is the generation of hydrogen using renewable electricity. Power-to-power refers to storing electricity in batteries.

At the turn of the twentieth century, Theodore Roosevelt became the 26th president of the U.S. and a few years later Henry Ford debuted the Model T in Detroit, Michigan. Only few visionaries at that time may have imagined a future with an intricate highway system, carrying people and goods from one coast to another in a matter of days. Or trolleys and streetcars becoming massive urban busses, running hundreds of people around a city center.

Data centers play a vital role in everyday life by ensuring we have uninterrupted access to information. They are on the rise globally, and with that comes increased focus on the environment and air quality.  As the industry strives for sustainable operations and cleaner air, both carbon and nitrogen oxide (NOx) emissions are being reduced. Regulations are playing a major role in this shift, especially when it comes to NOx emissions. 

A more sustainable world is one with lower emissions. By lowering greenhouse gases (GHGs) — like carbon dioxide (CO2) and methane (CH4), which contribute to climate change; and oxides of nitrogen (NOx ), which contribute to ozone depletion; and particulate matter (PM), which impacts air quality — we can improve the resiliency of our lives. 

As the automotive industry navigates the complexities of the energy transition, vehicle software is emerging as a key component in transforming how OEMs operate and innovate. The sophistication of vehicle software components can bring new capabilities and create a higher level of efficiency and safety.

The transportation industry is navigating the delicate balance between performance enhancement and sustainability. A pivotal aspect of this journey is the evolution of engine braking and Valvetrain technologies due to the direct link these components have with engine performance and fuel consumption. This article helps explain the latest developments around braking and Valvetrain technologies, and how they are contributing to improved performance while complying with emissions regulations.

A decade ago, turbochargers for natural gas and diesel engines were not very different. However, new emissions regulations have driven the development of turbochargers specifically designed for natural gas engines. These turbochargers are adapted to stoichiometric burn conditions, where the mix of oxygen and fuel is precisely balanced. This balance ensures efficient combustion, leaving no unburnt fuel or excess oxygen.

Sustainability in the transportation industry is a critical goal for Cummins Inc. We have been committed to leading the industry through the energy transition with Destination Zero – our strategy for reaching zero emissions. With a focus on reducing environmental impact through innovative technologies and practices, Cummins is leveraging its technological expertise, to lead the industry towards a greener, more sustainable path.
