Nearly a century ago, German chemist Fritz Haber won the Nobel Prize in Chemistry for a process to generate ammonia from hydrogen and nitrogen gases. The process, still in use today, ushered in a revolution in agriculture, but now consumes around one percent of the world's energy to achieve the high pressures and temperatures that drive the chemical reactions to produce ammonia.
Today, University of Utah chemists publish a different method, using enzymes derived from nature, that generates ammonia at room temperature. As a bonus, the reaction generates a small electrical current. The method is published in Angewandte Chemie International Edition [DOI: 10.1002/anie.201612500] [DX].

The very defining property of enzymes is that they are not consumed by the process. They are not converted or used up. Think of them as machines
Thats extremely optimistic. Its like catalysts in a car catconv or at a refinery. To a first approximation if a reaction takes a tiny fraction of a second they never wear out, but in practice due to impurities and contamination blah blah you replace every decade or so.
