    Introduction

    T here is a growing belief among poli cy-makers, environm

    energy analysts and industry leaders that hydrogen is the f

    will revolutioni se the way we produce and use energy. I n

    reliance on finite fossil energy is clearly unsustainable, both

    economi cally. Soaring prices of oi l in recent years have dr

    energy-security risks of relying on oil and gas, and hav

    perception that the world is starting to run out of cheap fue

    to move to more secure and cleaner energy technologies

    held to be the most promising of a number of such techno

    deployed on a large scale in the foreseeable future. Repla

    hydrogen in final energy uses could bring major environmen

    as technical, environmental and cost challenges in th

    produced, transported, stored and used are overcome.

    UNEP is following developments in hydrogen-energy te

    interest, as it holds out the prospect of providing the ba

    energy future one in which the environmental effects of en

    use are greatly reduced or eliminated. I ndeed, the hydroge

    What is Hydrogen?

    H ydrogen is the simplest, lightest and most abundant elem

    making up 90% of all matter. I t is made up of just one elec

    and is, therefore, the first element in the periodic table. I

    state, hydrogen is odourless, tasteless, colourless and non-to

    partial oxidation. A major shortcoming of the processing of hydrocarbons is th

    resulting emissions of carbon dioxide and airborne pollutants. M ost othe

    production processes in use or under development involve the electrolysis o

    water by electricity. T his method produces no emissions, but is typically mor

    costly compared to hydrocarbon reforming or oxidation because it require

    more energy and because electricity is, in most cases, more expensive than foss

    fuels. Today, the commercial production of hydrogen worldwide amounts to

    about 40 mi llion tonnes, corresponding to about 1% of the worlds primar

    energy needs. T his output is primari ly used as a chemi cal feedstock in th

    petrochemical, food, electronics and metallurgical processing industries.

    H ydrogen holds the potenti al to provide energy services to all sectors of th

    economy: transportation, buildings and industry. I t can complement or replac

    network -based electricity the other main energy carrier i n final energy uses

    H ydrogen can provide storage opti ons for intermittent renewables-base

    electricity technologies such as solar and wind. And, used as an input to a device

    known as a fuel cell, it can be converted back to electrical energy in an efficien

    way in stationary or mobile applications. For this reason, hydrogen-powered fue

    cells could eventually replace conventi onal oi l-based fuels in cars and trucks

    H ydrogen may also be an attractive technology for remote communities whic

    cannot economically be supplied with electricity via a grid. Because hydrogen

    can be produced from a variety of energy sources fossil, nuclear or renewable

    A Global Hydrogen Energy System

    T he transition to a hydrogen-energy system would represent the ultimate step o

    the path away from carbon-based fossil energy. T he worlds energy system ha

    been becoming gradually less carbon-intensive as it has moved from coal to o

    and then natural gas. T he technology exists today to produce, store, transport and

    convert hydrogen to useable energy in end-use applications, such as fuel cells

    Technologies to capture carbon dioxide and other gases released during th

    process of producing hydrogen from fossil fuels and store them have also been

    demonstrated. Almost every big car manufacturer plans to begin commercia

    Hydrogen Production, Distribution and Storage

    A critical hurdle on the road to the hydrogen economy is the efficient and clean

    production of hydrogen. As an energy carrier, hydrogen has to be manufacture

    from a primary energy source. T here are many industrial methods currentl

    available for the production of hydrogen, but all of them are expensive comparedwith the cost of supplying the same amount of energy with conventional form

    of energy ( several times more expensive compared with fossil fuels) . T h

    distribution and storage systems that would be needed to supply hydrogen on

    large scale are also much more expensive because of the low volumetric energ

    reductions in the cost of renewables-based electricity and nuclear power are

    needed to enable hydrogen produced by electrolysis to compete with

    conventional sources of energy on a large scale.

    T here is some scope for reducing the cost of producing hydrogen. In 2005, th

    US Department of Energy set a new production-cost target of $23 per gallon o

    gasoline equivalent ( in 2005 prices) by 2015, regardless of the way the hydroge

    is produced. Achieving the target would require a halving of the current cost

    Steam reformi ng of natural gas or some other fossil-fuel feedstock is likely to

    remain the cheapest way of producing hydrogen for the foreseeable future

    except where electricity is available at very low cost.

    H owever hydrogen is produced, i ts widespread use will require large-scal

    infrastructure to transport, distribute, store and dispense it as a fuel for vehicles o

    for stationary uses. Because of its low volumetric energy density, hydrogen must bcompressed and stored as a gas in a pressurised container or chilled and stored i

    demonstrated and are in commercial use today, but they use significant amount

    of energy and the tanks are expensive to build and operate. T he potential fo

    storing hydrogen safely and efficiently in a solid state is being investigated.

    Transportation and distribution are faced with similar problems. Compressed

    in 1839. T he term fuel cell was coined later in 1889 by Ludw

    Langer, who attempted to build the first practical device us

    Because there is no combustion, fuel cells give off no emissions other than wate

    vapour for as long as the hydrogen is pure. Fuel cells are quiet and reliable as

    there are no moving parts, and can be small. T hese attributes make fuel cells

    highly promising technology, especially for automoti ve vehicles. T hey can also b

    used in stationary applications, to provide electricity or heat for bui ldings.

    demonstrated in various places around the world: the most recent models worwell and prove popular with end users. M ost use the proton exchange o

    polymer electrolyte membrane (PEM ) technology. PEM fuel cells operate a

    relatively low temperatures of around 80 C, which allows a rapid start-up tim

    and causes less wear on system components. T hey have a higher power-to

    weight ratio than other types of fuel cell. H owever, they require a noble meta

    catalyst, which adds to the cost. O ther technologies under development includ

    the solid oxide fuel cell ( SO FC) , which uses a solid, non-porous cerami

    compound as the electrolyte, and operates at high temperatures; and thealkaline fuel cell, which uses a potassium hydroxide solution as the electrolyt

    together wi th non-precious metals as the catalysts at the anode and cathode

    operating at low to medium temperatures.

    kW or less. T his would be close to the current cost of a combined-cycle gas

    turbine power plant.

    Carbon Capture and Storage

    T he prospects for the hydrogen economy becoming a reali ty in the foreseeabl

    future hi nge on advances in carbon capture and storage (CCS) technology, an

    its integration into hydrogen production based on fossil fuels. T his is a necessar

    but not a sufficient, condition. Success in deploying CC S would also pave the wa

    for environmentally acceptable production of electricity using fossil fuelshydrogen would still have to compete against electricity in final energy uses

    including transport.

    T here are three distinct steps involved in CCS associated with hydroge

    production:

    Capturing CO 2 from the flue-gas streams emitted during the productio

    process ( pre-combustion capture) .

    Transporting the captured CO 2 by pipeline or in tankers.

    Storing CO 2 underground in deep saline aquifers, depleted oil and ga

    reservoirs or unmineable coal seams.

    CO 2 capture and transportation has been carried out for decades, albeit generall

    on a small scale and not with the purpose of ultimately stori ng it. T here is a neeto improve these technologies for them to be widely deployed on a large scale in

    association with hydrogen production, and to lower the cost. At present, mos

    capture research and development is focused on post-combustion capture from

    burning fossil fuels in power plants. M uch more work also needs to be done o

    carbon storage to demonstrate its viabili ty and reduce the cost ( Box 6) .

    T he future cost of CCS will depend on which technologie

    are applied, how far costs fall as a result of research and deve

    At present, the total cost of CCS typically ranges from $50 to $100 per tonne o

    CO 2. T his is equivalent to about 1530 US cents per gallon of gasoli ne, $204

    per barrel of crude oil or 24 US cents per kWh roughly equal to the curren

    cost of gas-fired power generation. By comparison, the average price of a perm

    to emit one tonne of CO 2 under the European Emission Trading Scheme wa

    around $28 in September 2005. CCS costs could drop significantly in future

    perhaps by half within the next 25 years depending on funding for research an

    development and the success of demonstration projects. I n thi s case, C CS woulbecome competitive in Europe, even without any increase in carbon values.

    CCS will not ensure a sustainable energy future, as fossil fuel resources are finite

    But, if integrated into the production of hydrogen and/or electricity, it coul

    provide the basis for a more sustainable energy system over a transitional period

    lasting at least several decades. T he planets fossil-fuel resources are far from

    being depleted. Proven reserves of oil are equal to 40 years of curren

    production; natural gas reserves are equal to 67 years, and coal reserves, 16years ( BP, 2005) . Exploration and improved production technologies tha

    enhance recovery rates will undoubtedly increase these reserves. I n the very lon

    term, as fossil resources are eventually depleted, mank ind wi ll have no choic

    but to turn to renewable energy technologies if they have not becom

    competitive with fossil fuels associated with CCS before then.

    enough centralised hydrogen plants to supply the fuel needed to run all the cars

    trucks and buses in use in the world today would require a staggering $8 tri llion

    in investment not including the cost of carbon capture. T his sum is equal to

    almost half the total cumulative investment in the entire energy sector that th

    International Energy Agency estimates will be needed worldwide over the nex

    quarter of a century ( IEA, 2005a).

    Cost is the principal barrier to investment in hydrogen. No private firm will invesin a commercial hydrogen venture unless it believes that it will be able to

    compete against existing fuels and turn a profit. H ydrogen is sti ll far from bein

    competitive in most applications, but that could change with technologica

    breakthroughs and government incentives or mandates. I f that is the case, th

    opportunities for profitable development of hydrogen facilities would expan

    over time. Initially, i nvestment may be limited to a few remote locations, wher

    the costs of fuel distribution and electricity infrastructure are relatively high

    where public concern about environmental sustainability is especially strong andwhere governments provide large incentives. As the market develops mas

    production of supply equipment and fuel cells will bring economies of scale

    advance the learning process and further lower costs.

    But cost is not the only barrier to investment. As with any radically new

    technology, hydrogen could face the classic chicken-and-egg conundrum: th

    lack of a market in the first place deters investment, preventing the market from

    developing. Put another way, why develop hydrogen cars when there is ndistribution network, and why develop a distribution network if there are no

    hydrogen cars? H ydrogen use will not take off unti l critical market mass i

    achieved. T he market needs to be large enough to demonstrate to potentia

    users and fuel providers that hydrogen is a safe, reliable and cost-effectiv

    alternative to conventional fuels. T he more fuel-cell vehicles there are on th

    road, the more confidence other vehicle owners will have to switch fuels. And

    the hydrogen refuelling network would have to be developed quickly: a lack o

    refuelling stations would be a major impediment to persuading vehicle ownerto switch to hydrogen, even if there were a financial incentive to do so.

    The sheer scale of investment in a hydrogen project, together with inheren

    technical and financial risks, could also discourage private companies. G overnmen

    Government Support

    For the transition to the hydrogen economy to begin, there will most likely be a

    need for decisive government action in two areas:

    Research, development and demonstration of hydrogen technologies. T hi

    effort could be vital to achieving the necessary technological breakthroughs

    Incentives to encourage investment in hydrogen infrastructure and switchinto the fuel once technologies are deemed to be economic.

    Because hydrogen is a long way from becoming competitive, the focus o

    government action today in the field of hydrogen is in research and developmen

    ( R& D ) . Research i nto the use of hydrogen for energy purposes goes back man

    decades, but the scale of publi c ( and private) funding for hydrogen and fuel ce

    R& D and demonstration activi ties has increased enormously in the last few years

    T his reflects significant technological advances that make it more li kely that thfuel will become a viable energy solution in the not too distant future, as well a

    a growing urgency on the part of policy-makers to seek out sustainable energ

    solutions that address environmental and energy-securi ty concerns. M an

    governments now expect the transition to the hydrogen economy to begin

    within the next two decades and are look ing to speed up the process, ofte

    through collaborative international and joint private-public sector programmes

    T he International Energy Agency ( I EA) estimates that current public hydrogeR& D spending worldwide amounts to about $1 billion per year ( IEA, 2004a)

    T his spending might seem impressive, but is actually modest compared to th

    sums governments are spending on other forms of energy R& D . I n membe

    countries of the O rganization for Economic Cooperation and D evelopmen

    ( O ECD ) , hydrogen accounts for only about 15% of total energy R& D budgets

    R& D spending on hydrogen is thought to exceed that on fossil fuels an

    renewables, but is sti ll much lower than that on nuclear energy. I n 2001 th

    latest year for which comprehensive data is available O ECD countri es spen$3.8 billion on nuclear energy, $700 mi llion on fossil fuels and $760 mi llion o

    renewables ( I EA, 2004d) . Total O ECD R& D spending in that year was $8.

    standards and codes for designing, building, testing and ultimately marketing

    hydrogen-related equipment. T hey will be crucial to ensuring safety and

    lowering costs. I nternational harmonisation of standards would encouragtrade and avoid parallel development of incompatible equipment an

    technology lock-in with di fferent standards, further dri ving down costs

    G overnments will also be called upon to assist in promoti ng public awarenes

    about the benefits of hydrogen, as well as the training and education o

    industry personnel.

    Long-Term Projections of Hydrogen UseI t is extremely hard to predict how soon the transition to hydrogen as an energ

    carrier might begin and how long it might take, as it depends critically on

    technology breakthroughs in a number of different areas. I t is impossible t

    know when these might occur and the extent to whi ch they will lower costs an

    enhance the competi tiveness of hydrogen vis--vis conventional forms of energy

    As a result, all long-term projections of hydrogen use are based on assumption

    about supply costs.

    H owever successful current hydrogen R& D efforts are in bringing down cost

    and improving performance, the transition process to a hydrogen econom

    would undoubtedly be gradual, probably lasting several decades. T he planning

    construction, operation and decommissioning of energy infrastructure stretch

    over very long timeframes. C ars and trucks typically last a decade or two, bu

    power stations, oil refineries and pipelines are built to last for decades. Retiring

    them early would be very expensive. And the widespread deployment of carbon

    capture and storage technology will be a mammoth undertaking. M obilising athe investment needed to completely overhaul the entire existing energy system

    within a decade or two would simply not be practical, even if we were prepared

    to pay the enormous cost of phasing out existing energy facili ties early. So, eve

    if competitive hydrogen technologies were to emerge within the next 20 years,

    would probably take most of the rest of this century to complete the transitio

    Relevance of Hydrogen to Developing Economies

    Although most current hydrogen R& D is taking place in the industrialise

    countries, developing economies have as much if not more to gain frommoving to the hydrogen economy. Their towns and cities generally suffer far mor

    from the pollution caused by road traffic, coal-fired power stations and industria

    boi lers. M any developing economies are more economi cally vulnerable t

    fluctuations in international energy prices, as their economies are more energy

    the quicker they could achieve energy sustainability.

    T he initial focus of efforts to establish hydrogen syseconomies will most likely be on transport and possibly o

    As hydrogen technologies approach the stage at which they are ready to b

    commercialised, policy-makers will need to pay more attention to the

    implications for the transition to hydrogen of immediate decisions abou

    investment in large-scale conventional energy infrastructure. As developin

    economies grow richer, they will build thousands of power plants, as well as new

    refineries and pipeline systems. T hese facili ties will be intended to last man

    decades. Replacing them before the end of their economic lifetimes would be

    very expensive. T here is a risk that a decision taken today to pursue conventional energy project will hinder the introduction of hydroge

    technologies at some point in the future, by anchoring the energy system to

    fossil fuels. T here is inevitably a trade-off between the benefits of providin

    modern energy services today and developing a sustainable energy system in the

    longer term. T here is an urgent need to make available those services to the tw

    billion people in the developing world that do not yet have them. Waiting fo

    affordable clean energy solutions to emerge is neither a practical nor a morally

    acceptable option.

    T he best way to ensure that energy investment is undertaken in the mos

    economically efficient manner i s to establish a market-based policy framework

    T he aim should be to establish competi tive markets and effective mechanisms fo

    regulating natural monopolies, and to make sure that energy is priced correctly

    In properly regulated, well-functioning markets, competition ensures that the fu

    costs of supplying energy are reflected in the price the consumer pays. I n practice

    this is often far from the case. I n many developing economies, energy is heavilsubsidised, leading to excessive consumption and waste, and exacerbating th

    harmful effects of energy use on the environment. Subsidies can also place

    heavy burden on government finances and undermine private and publi

    investment in the energy sector, impeding the expansion of distribution network

    and the development of more environmentally benign energy technologies.

    G etting energy prices right does not stop there. T he environmental and healt

    costs of harmful emissions from burning fossil fuels are rarely reflected in thprices of those fuels, especially coal, in most countries developing and

    industrialised alik e. T here is no perfect way to do this, but one sensible approac

    is for governments to tax the consumption of each form of energy according to

    how much carbon dioxide and/or noxious gases it emits. At a minimum, the

    dirti est fuels should be taxed more. I n that way, the external environmental cost

    Key Messages

    H ydrogen holds out the promise of a truly sustainable global energy future. As

    clean energy carrier that can be produced from any pri mary energy source

    hydrogen used in highly efficient fuel cells could prove to be the answer to ou

    growing concerns about energy securi ty, urban pollution and climate change

    T his prize surely warrants the attention and resources currently being di rected a

    hydrogen even if the prospects for widespread commercialisation of hydrogen

    in the foreseeable future are uncertain.

    Considerably more research and development will be needed to overcome th

    formidable technical and cost hurdles that currently stand in the way o

    hydrogen. Large reductions in unit costs, notably in bulk transportation an

    storage, and in fuel cells, are needed for hydrogen to become competitive with

    existing energy systems. Finding a practical solution to the problem of storing

    hydrogen on board vehicles is a critical challenge. G overnments, energ

    companies, car makers and equipment manufacturers, who between them arinvesting bill ions of dollars in hydrogen-supply and fuel cell R& D an

    demonstration, are confident that these challenges can be overcome

    Unexpected technological breakthroughs stemmi ng from advances in basi

    sciences, which could have a revolutionary impact on hydrogen supply and fue

    cells, cannot be ruled out.

    I f technological and cost breakthroughs were to be achieved in the near future, th

    transition to a hydrogen energy system would sti ll take several decades. The slowturnover of the existing stock of capital that either makes or uses energy and th

    sheer amount of capacity that would need to be built to replace existing system

    and to meet rising demand will mean that fossil fuels will most likely remain th

    backbone of the global energy system unti l at least the middle of the century.

    National and Regional Programmes

    M ost O ECD countries and a growing number of developing economies have activ

    hydrogen and fuel-cell R& D programmes, wi th aggregate public fundin

    worldwide now running at about $1 billion per year. Fuel cells account for abou

    half of this spending. M ost of the rest is devoted to production, transportation an

    storage, with small amounts going to end-use technologies not based on fuel cells

    such as gas turbines and internal combustion engines. Total spending haincreased sharply in the last few years. The biggest increases in funding in dolla

    terms have occurred in the United States and the European Union. Almost all othe

    countries that undertake hydrogen R& D have also stepped up their activities.

    Some countries have integrated R& D programmes that cover all elements o

    hydrogen supply and end uses. O thers focus on specific aspects. In each case

    the balance of funding between different research areas reflects a mixture o

    national policy priorities, indigenous resource endowment, and researchtraditi ons and strengths. For example, the CO AL21 programme in Australia,

    country with very large coal reserves, covers hydrogen production from coa

    United States

    T he US government carries out most of its hydrogen and fuel-cell R& D under thH ydrogen, Fuel Cells and Infrastructure Technologies Program, run by th

    D epartment of Energy. T he governments strategy is to concentrate funding on

    high-risk applied research on technologies in the early stages of development

    and leverage private-sector funding through partnerships. T he administration

    sharply increased funding in 2003, with the launch of a five-year $1.2 billion

    European Union

    M ost EU funding for hydrogen-related activiti es is provided under the Renewabl

    Energy Sixth Framework Programme, which runs from 2002 to 2006. Som

    100 mi llion ( $120 milli on) of EU funds, matched by an equivalent amount o

    private investment, has been awarded to R& D and demonstration proj ects fohydrogen and fuel cells after the first call for proposals in 2003. Further calls fo

    R& D proposals, worth a public and private investment of 300 million ( of whic

    EU funding will amount to 150 mi llion) , are planned. Total public and privat

    funding is expected to reach 2.8 billion over the ten years to 2011. O f thi

    amount, production-related projects will account for 1.3 billion and end-us

    projects in communities, 1.5 billion. Some other EU programmes also includ

    some activities related to hydrogen.

    All the hydrogen projects that are being funded by the European U nion ar

    intended to support the large-scale Qui ck Star tinitiative, which aims to attrac

    private investment in infrastructure projects in partnership with national publi

    institutions and the European Investment Bank. T he ultimate goal is t

    accelerate the commercialisation of hydrogen-related technologies during th

    coming decades. Production-related projects aim to advance cutting-edg

    research to build a large-scale demonstration plant that is able to produce

    hydrogen and electricity on an industrial scale and to separate and store safel

    the CO 2 generated in the process. End-use projects are intended to explore th

    economic and technical feasibility of managing hydrogen-energy communities

    known as the hydrogen village. T his will involve establishing centralised an

    decentralised hydrogen production and distribution infrastructure
