Skref í átt að vetnishagkerfinu. Vistferilskostnaðargreining fyrir vetnisáfyllingarstöð: Tilviksrannsókn
Hlýnun jarðar hefur verið talið ótvírætt vandamál síðustu ár og hafa helstu merki þess verið bráðnun íss, hækkun meðalhitastigs jarðar og hækkandi sjávarborð. Aðalástæða þessa breytinga hefur verið talin losun gróðurhúsalofttegunda af mannavöldum. Ein leið til þess að minnka losun gróðurhúsategunda …
