"WebThe heat value of a fuel is the amount of heat released during its combustion. Also referred to as energy or calorific value, heat value is a measure of a fuel's energy density, and is expressed in energy (joules) per specified amount ( e.g. kilograms). Uranium figures are based on 45,000 MWd/t burn-up of 3.5% enriched U in LWR " - Higher heating value of hydrogen

Higher heating value of hydrogen

WebWhere local heat off-take is available, the economic case for biogas co‑generation is stronger than for an electricity-only plant. This is because co‑generation can provide a higher level of energy efficiency, with around 35% of the energy from biogas used to generate electricity and an additional 40-50% of the waste heat put to productive use.
