VOLTENERTEC
Which energy source suits which equipment
EVs, homes, industrial plants and mobility — energy sources compared against the equipment that has to run on them.
What this site covers
Nine subject areas, written from the point of view of an engineer who has to select, wire and commission the equipment. An energy source is never assessed on its own, but together with the equipment that actually turns it into power.
Secondary batteries
Cell structure and voltage behaviour
Fuel cells
Stack layout and flow-field design
Renewable energy
PV arrays and inverters
Nuclear power
Thermal cycle and grid configuration
Energy comparison
Which source wins, under which conditions
Equipment technology
PLC I/O maps and interlocks
Power systems
UPS and ESS single-line diagrams
Renewable energy systems
PCS and ESS grid interconnection
Nuclear power systems
System blocks and monitoring loops
How articles are written
Efficiency figures and market sizes matter less than what those figures change in the equipment and in the operating sequence.
Conclusion first
The judgement comes in the opening paragraph, the evidence after it.
Comparison table, then the implication
Every table is followed by one sentence saying what it means.
Boundary conditions stated
Each article ends with the conditions under which its conclusion flips.
Sources named
Reports, statutes and patents are cited with publisher, date and patent number in the body text.
The remaining principles — no guessing, standards and safety first — are on the About page. All principles →
