Wind and photovoltaic power will likely account for around 40 percent of China’s total installed power generation capacity by the end of this year, compared with coal’s 37 percent, according to the CEC.
Sinohytec's 240KW fuel cell engine can power 49t heavy duty trucks, which I find a little surprising. I'd think you need more than that. It's costs are out of date I think. Latest Sinohytec Q&A with investors say cost has been lowered to 2000-3000RMB/KW. Still expensive if you multply 2500 * 240 = 600k RMB过去几年，燃料电池诸多技术难题得以破解，功率不断提升。亿华通新一代大功率燃料电池发动机的额定功率达到240千瓦，已经能满足49吨载重的重卡持续运行。每千瓦燃料电池的成本也从两万元降到了三五千元，更有助于氢燃料车推广。
says here that you can get electricity generation efficiency to 56%, which is still not great vs combined cycle gas turbine, but it's not terrible. The problem is that we loose a lot from green electricity -> hydrogen -> electricity3）含氢废气耦合燃料电池发电的能量转化率高，发电效率约 56%。发电系统灵活，中压合成气可实现低成本储存，通过储存气体用于调峰，电堆可根据来气量增减负荷以实现调峰运行。 （4）氢燃料电池发电后可直接进入企业、饭店、宾馆或家庭，实现热电联产联用，过程中几乎没有输电输热损失，对能源的综合利用率可达 80%。
