l cells are being developed for use in residential off grid deployment 94 cogeneration edit see also combined cycle hydrogen power plant combined heat and power chp fuel cell systems including micro combined heat and power microchp systems are used to generate both electricity and heat for homes see home fuel cell office building and factories the system generates constant electric power selling excess power back to the grid when it is not consumed and at the same time produces hot air and water from the waste heat as the result chp systems have the potential to save primary energy as they can make use of waste heat which is generally rejected by thermal energy conversion systems 95 a typical capacity range of home fuel cell is 1 3 kw el 4 8 kw th 96 97 chp systems linked to absorption chillers use their waste heat for refrigeration 98 the waste heat from fuel cells can be diverted during the summer directly into the ground providing further cooling while the waste heat during winter can be pumped directly into the building the university of minnesota owns the patent rights to this type of system 99 100 co generation systems can reach 85 efficiency 40 60 electric and the remainder as thermal 6 phosphoric acid fuel cells pafc comprise the largest segment of existing chp products worldwide and can provide combined efficiencies close to 90 101 102 molten carbonate mcfc and solid oxide fuel cells sofc are also used for combined heat and power generation and have electrical energy efficiencies around 60 103 disadvantages of co generation systems include slow ramping up and down rates high cost and short lifetime 104 105 also their need to have a hot water storage tank to smooth out the thermal heat production was a serious disadvantage in the domestic market place where space in domestic properties is at a great premium 106 delta ee consultants stated in 2013 that with 64 of global sales the fuel cell micro combined heat and power passed the conventional systems in sales in 2012 81 the japanese ene farm project stated that 34 213 pemfc and 2 224 sofc were installed in the period 2012 2014 30 000 units on lng and 6 000 on lpg 107 fuel cell electric

california s false advertising law and breaches of implied warranty 119 the same year hyundai recalled all 1 600 nexo vehicles sold in the us to that time due to a risk of fuel leaks and fire from a faulty pressure relief device 120 criticism edit some commentators believe that hydrogen fuel cell cars will never become economically competitive with other technologies 121 122 123 or that it will take decades for them to become profitable 80 124 elon musk ceo of battery electric vehicle maker tesla motors stated in 2015 that fuel cells for use in cars will never be commercially viable because of the inefficiency of producing transporting and storing hydrogen and the flammability of the gas among other reasons 125 in 2012 lux research inc issued a report that stated the dream of a hydrogen economy is no nearer it concluded that capital cost will limit adoption to a mere 5 9 gw by 2030 providing a nearly insurmountable barrier to adoption except in niche applications the analysis concluded that by 2030 pem stationary market will reach 1 billion while the vehicle market including forklifts will reach a total of 2 billion 124 other analyses cite the lack of an extensive hydrogen infrastructure in the u s as an ongoing challenge to fuel cell electric vehicle commercialization 82 in 2014 joseph romm the author of the hype about hydrogen 2005 2025 said that fcvs still had not overcome the high fueling cost lack of fuel delivery infrastructure and pollution caused by producing hydrogen it would take several miracles to overcome all of those problems simultaneously in the coming decades 126 he concluded that renewable energy cannot economically be used to make hydrogen for an fcv fleet either now or in the future 121 greentech media s analyst reached similar conclusions in 2014 127 in 2015 cleantechnica listed some of the disadvantages of hydrogen fuel cell vehicles 128 so did car throttle 129 a 2019 video by real engineering noted that notwithstanding the introduction of vehicles that run on hydrogen using hydrogen as a fuel for cars does not help to reduce carbon emissions from transportation the 95 of hydrogen still produced from fossil fuels releases carbon dioxide and producing hydrogen from water is an energy consuming process storing hydrogen requires more energy either to cool it down to the liquid state or to put it into tanks under high pressure and delivering the hydrogen to fueling stations requires more energy and may release more carbon the hydrogen needed to move a fcv a kilometer costs approximately 8 times as much as the electricity needed to move a bev the same distance 130 a 2020 assessment concluded that hydrogen vehicles are still only 38 efficient while battery evs are 80 efficient 131 in 2021 cleantechnica concluded that a hydrogen cars remain far less efficient than electric cars b grey hydrogen hydrogen produced with polluting processes makes up the vast majority of available hydrogen c delivering hydrogen would require building a vast and expensive new delivery and refueling infrastructure and d the remaining two advantages of fuel cell vehicles longer range and fast fueling times are rapidly being eroded by improving battery and charging technology 132 a 2022 study in nature electronics agreed 133 a 2023 study by the centre for international climate and environmental research cicero estimated that leaked hydrogen has a global warming effect 11 6 times stronger than co 2 134 buses edit toyota fchv bus at the expo 2005 as of august 2011 update there were about 100 fuel cell buses
