Question 5: Why do you Sample Clauses

Question 5: Why do you believe H2 does not have a future or will have difficulty being realised in transport? Responses to this question came from 43 of the 50 people interviewed (86%). While only 2 people interviewed did not believe that H2 could or should be an energy source for transport into the future, everyone believed there were significant obstacles to be overcome. Their comments have been grouped into 7 categories as follows6: Cost of a H2 based transport system 26% 53% Major technological and other challenges7 21% 44% Competition from alternative energy sources 16% 33% Efficiency of H2 as an energy source 12% 26% H2 has not fulfilled potential nor is it a short term ‘fix’ 12% 26% Lack of understanding of and communication about H2 potential 7% 14% Safety concerns about H2 6% 12% Table 4: Why does H2 NOT have a future in Transport Energy? 3.5.1 Cost of a H2 based transport system Cost is high; cost risk if battery technology takes off and (given) the increased efficiency of ICE; investment needed very high; business case needs to be done on this; currently very reliant on public funding for resolving technical issues; H2 is very costly and most (companies) want return as soon as possible; no guarantee that large investment will be rewarded with success; cost of infrastructure; business case for H2 in stationary energy needs to be made before a similar one is made for transport; doubtful will get the injection of investment needed and we are unlikely to see subsidies supporting particular technologies – no repeat of the natural gas subsidy; (Distribution of H2) to even 10% of the 14,000 filling stations in Germany would be very costly; cost is high – who will pay?; from infrastructure perspective costs must come down; cost is a major issue for transport companies; there is nothing to suggest costs of the Fuel Cell will come down; cost is a huge problem - 1.5 million for FC bus compared with 250,000 for a natural gas bus). 3.5.2 Major technological and other challenges to be overcome
