Why Range Extenders Could Hit 50% Thermal Efficiency: The Waste Heat Recovery Comeback Internal combustion engines waste roughly 60% of the energy they consume — most of it as heat dumped into the exhaust and the coolant. For a century, that loss was accepted as a law of physics. It was not. New series-hybrid architectures,…
EREVs, e-Fuels and Natural Hydrogen: The Real European Energy Strategy Nobody Is Explaining In just six months, between December 2025 and March 2026, four major announcements have quietly reshaped the European energy and mobility landscape. Each one made headlines individually. None has been connected to the others. Together, they tell a story that contradicts almost…
The Inconvenient Math: What Happens to a kWh Between the Power Plant and Your EV Battery Public discourse treats an electric vehicle charged on the European grid as if the kilowatt-hour at the socket came directly from sunlight or wind. In reality, the chain from primary energy to wheels is full of losses — and…
Roundtable on Sustainable Biomaterials publishes operational framework for renewable fuel operators navigating the EU’s revised Renewable Energy Directive requirements.
As the Renewable Energy Directive III compliance framework enters force in late April 2026, biofuel and sustainable aviation fuel operators face new certification requirements under EU mandates.
