The founder and chairman of Lawrence Energy Group LLC, David Lawrence spent the majority of his career as an executive with Shell Upstream Americas in Houston and Royal Dutch/Shell in London and The Hague. He retired from Shell in 2013. Starting his career at the United States Geological Survey and in Shell’s Bellaire Research Center, David Lawrence is a longtime advocate of energy research and development, particularly in areas such as carbon capture and storage (CCS).

CCS refers to the process of capturing carbon dioxide from fossil fuel combustion before it is released into the atmosphere. Once the carbon dioxide is captured, it must be stored in such a way that it does not leak into the surrounding environment and cause damage.

Carbon capture typically involves separating carbon dioxide from the other gases produced in industrial applications and electricity generation. Pre-combustion capture involves converting fuel into a mixture of gases before ever burning it for energy. In post-combustion capture, engineers extract carbon dioxide from combustion exhaust using membrane filtration, adsorption, or cryogenic separation.

After capturing carbon dioxide, engineers typically store the gas in geological rock formations several miles below the surface of the earth. Ideal candidates for carbon storage areas include some select former gas and oil fields, which have already been assessed thoroughly in geological and hydrodynamic terms.

A former executive with Shell Upstream Americas and Royal Dutch Shell, David Lawrence has been a fixture in the US energy industry for more than 30 years. Now the head of Lawrence Energy Group, LLC, a consultant and lecturer, he has worked with groups such as the Yale Climate and Energy Institute to brainstorm solutions for adapting to climate change. David Lawrence keeps up with current trends in the renewable energy sector, such as solar panels.

Tesla recently debuted new solar roof panel technology aimed at providing a practical method of capturing solar energy. The technology employs a mix of glass tiles, solar tiles, and regular nonsolar tiles to provide
energy for a home’s needs.

According to Tesla, a solar roof designed for a 3,000 square-foot house comes in at just over $65,000, a hefty price tag that homeowners will have to pay up-front to gain potential energy savings in the future. This figure includes incentives such as the Solar Investment Tax Credit and other state and local tax credits.

In areas that get plentiful sunshine, the investment makes sense over a 30-year period, with homes in California, for example, showing a net gain in saved energy cost compared to the installation cost. In other areas, however, the energy savings may not quite reach the threshold. Homeowners should assess their specific situations and use Tesla’s cost calculator to determine if the solar roof is a good fit for their energy needs.

The Need for More Energy and Less CO2

David Lawrence, a highly proficient geologist and business leader, earned degrees from Lawrence University and Yale University, and possesses decades of experience in the oil, gas and energy industry with Royal Dutch Shell. After retiring from Shell, David Lawrence founded Lawrence Energy Group and has established himself as an expert in the subject area of energy transitions and the need for energy expansion. Recently, Mr. Lawrence published an article in Western Confluence magazine titled Energy Transition, Our World Needs More Energy and Less CO2. Western Confluence is a magazine that partners with the Ruckelshaus Institute at the University of Wyoming to provide content on issues affecting natural resources in the western United States. The energy transition article discusses the challenge of meeting the increasing global demands for energy while also simultaneously decreasing CO2 emissions. The need for leadership, innovation, and research and development is also important, in order to move closer to the ideal energy system which features affordability and availability while also being safe, sustainable, and environmentally friendly.
