Early Stage Cleantech Venture and the Next Billion Dollar Businesses

Early Stage Cleantech Venture and the Next Billion Dollar Businesses

Looks at how cleantech has the potential to produce the next billion dollar companies and become the engine of growth for the US; and goes on to look at how the entrepreneurial ecosystem can be encouraged, especially in the critical early stage phase.

Brown to Green: A New Use For Blighted Industrial Sites

Brown to Green: A New Use For Blighted Industrial Sites

Few places in the U.S. are as well suited to developing renewable energy as the contaminated sites known as “brownfields.” But as communities from Philadelphia to California are discovering, government support is critical to enable solar and wind entrepreneurs to make use of these abandoned lands.

Not Enough Funding for Your Cleantech Startup? Making It Across The Valley of Death

Not Enough Funding for Your Cleantech Startup? Making It Across The Valley of Death

Many cleantech entrepreneurs are in the tough place we commonly call the Valley of Death. Stable, but underfunded, which they need for growth. If this describes your company, find out what you should do.

12 Synthetic Biology Biofuel & Biochemical Companies to Watch

12 Synthetic Biology Biofuel & Biochemical Companies to Watch

A detailed review of 12 U.S. based synthetic biology, biofuel & biochemical companies that are developing third and fourth generation biofuels, bioindustrial & household chemical, and food additive products; using synthetic biology to produce engineered microorganisms and specialty enzymatic products. Each company is examined in turn, looking at its financials and the uniqueness and strength of its processes and technology as well as at any important partnerships or alliances that have been formed.

12 Clean Energy Trends to Watch in 2011 and Beyond

12 Clean Energy Trends to Watch in 2011 and Beyond

The clean energy sector is entering a phase of dramatic change in which business models are being transformed against a backdrop of regulatory uncertainty, as the industry emerges from a challenging period caused by the global economic downtown. Technologies and business structures that were once abandoned, are now being revived in several key sectors.

Is the Concentrated Photovoltaic Sector Heating Up?

Is the Concentrated Photovoltaic Sector Heating Up?

Concentrated solar photovoltaic energy or CPV is a relative newcomer to the solar power arena and is showing signs of entering into a phase of very rapid growth. It works by concentrating the sun onto a small area of active PV, which operates at around twice the efficiency of normal PV, and promises savings because it requires only a fraction of the photovoltaic material that normal systems require. The DOE has announced a $90 million loan guarantee to support a planned 30-megawatt facility near Alamosa, Colorado.

Ultra High Voltage (UHV) Transmission is the Renewable Energy Interstate

Ultra High Voltage (UHV) Transmission is the Renewable Energy Interstate

While other parts of the world are busy actually building national Ultra High Voltage (UHV) transmission infrastructure the US continues to do noting more substantial than litigate. A UHV super grid would be able to move renewable energy from where it is abundant to where people live and work, and do so at an economic cost. This kind of national electric energy infrastructure would enable solar, wind, hydro and geothermal generated electric power to reach market. It is a critical piece of the kind of future energy infrastructure we will need in order to continue to prosper. John goes into a lot of detail and provides numerous links to examples and more in depth reading on this very important subject.

Does Concentrated Solar Power Have the Answer to Intermittency Concerns?

Does Concentrated Solar Power Have the Answer to Intermittency Concerns?

In this post John outlines two developments in the thermosolar concentrated solar power (CSP) arena that are enabling CSP to fulfill the role of baseload suppliers. Molten salt energy storage is naturally suited for CSP facilities and is quite efficient as an energy store — both in terms of low loss and in terms of capital expenditures (compared with batteries for example). By storing power in this way CSP plants can continue delivering power even after the sun has gone down. In addition by pairing CSP with stand-by combined-cycle natural gas generators greater overall reliability can be achieved.

Sustainable Nukes?

Sustainable Nukes?

The nuclear crisis in Japan is a wake up call demonstrating that nuclear power is not the silver bullet against climate change that governments and advocates have claimed. Much more effort, resources and political will has to be directed toward alternative sources of energy: energy saving, renewable, and changing of life styles.
